Basis of Presentation and Consolidation and Recently Issued Accounting Standards	9 Months Ended
	Jun. 30, 2011
Basis of Presentation and Consolidation and Recently Issued Accounting Standards [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Basis of Presentation and Consolidation and Recently Issued Accounting Standards INTL FCStone Inc., a Delaware corporation, together with its consolidated subsidiaries (collectively “INTL” or “the Company”) form a financial services group focused on domestic and select international markets. The Company’s services include comprehensive risk management advisory services for commercial customers; execution of listed futures and options on futures contracts on all major commodity exchanges; structured over-the-counter ("OTC") products in a wide range of commodities; physical trading and hedging of precious and base metals and select other commodities; trading of more than 130 foreign currencies; market-making in international equities; debt origination and asset management. During the quarter ended March 31, 2011, the Company changed its name from International Assets Holding Corporation to INTL FCStone Inc., following approval of the name change by the Company's stockholders. The Company provides these services to a diverse group of approximately 10,000 customers located throughout the world, including producers, processors and end-users of nearly all widely-traded physical commodities to manage their risks and enhance margins; to commercial counterparties who are end-users of the firm’s products and services; to governmental and non-governmental organizations; and to commercial banks, brokers, institutional investors and major investment banks. Basis of Presentation and Consolidation The accompanying condensed consolidated balance sheet as of September 30, 2010, which has been derived from audited financial statements, and the unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and note disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to those rules and regulations. The Company believes that the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the condensed consolidated financial statements for the interim periods presented have been reflected as required by Rule 10-01 of Regulation S-X. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year. It is suggested that these interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes contained in the Company’s Form 10-K for the fiscal year ended September 30, 2010 filed with the SEC. These condensed consolidated financial statements include the accounts of INTL FCStone Inc. and its subsidiaries. Intercompany transactions and balances have been eliminated in consolidation. In accordance with the Consolidation Topic of the Accounting Standards Codification ("ASC"), the Company consolidates any variable interest entities for which it is the primary beneficiary, as defined. The Company has a majority interest in the Blackthorn Multi-Advisor Fund, LP (the “Blackthorn Fund”). The Blackthorn Fund is a commodity investment pool, which allocates most of its assets to third-party commodity trading advisors and other investment managers. The Blackthorn Fund engages in speculative trading of a wide variety of commodity futures and options on futures contracts, securities and other financial instruments. In addition to the majority interest that was acquired, a subsidiary of the Company is also the general partner of the Blackthorn Fund. Under the provisions of the Consolidations Topic of the ASC, the Company is required to consolidate the Blackthorn Fund as a variable interest entity since it is the general partner and owns a majority interest. The creditors of the Blackthorn Fund have no recourse to the general assets of the Company. The Blackthorn Fund had net assets of $3.6 million as of June 30, 2011. The net assets of the Blackthorn fund consisted of cash and cash equivalents of $0.9 million, deposits and receivables from broker-dealers, clearing organizations and counterparties of $2.8 million, investments in managed funds of $1.2 million and $1.3 million in accounts payable and other accrued liabilities at June 30, 2011. Accordingly, the noncontrolling interest shown in the condensed consolidated balance sheets includes the noncontrolling interest of the Blackthorn Fund of $1.3 million as of June 30, 2011. See Note 6 for discussion of fair value of the financial assets and liabilities. Our fiscal year end is September 30, and our fiscal quarters end on December 31, March 31, June 30 and September 30. Unless otherwise stated, all dates refer to our fiscal years and fiscal interim periods. The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses. The most significant of these estimates and assumptions relate to fair value measurements for financial instruments and investments and the provision for potential losses from bad debts. Provisions for estimated bad debts are recorded on a specific identification basis. Although these and other estimates and assumptions are based on the best available information, actual results could be materially different from these estimates. Reclassifications During the quarter ended March 31, 2011, the Company reclassified give-up fee revenue within the condensed consolidated income statement to the financial statement line caption 'commission and clearing fees', from 'consulting and management fees'. Reclassifications in the amount of $0.6 million and $1.2 million have been made to the three and nine month periods ended June 30, 2010, respectively, to conform to the current year presentation. These reclassifications had no effect on previously reported total or net revenues. Recently Issued Accounting Standards In June 2009, new guidance was issued on transfers and servicing of financial assets to eliminate the concept of a qualifying special-purpose entity, change the requirements for off balance sheet accounting for financial assets including limiting the circumstances where off balance sheet treatment for a portion of a financial asset is allowable, and require additional disclosures. The guidance was effective at the beginning of the Company’s 2011 fiscal year. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. In June 2009, new guidance was issued to revise the approach to determine when a variable interest entity ("VIE") should be consolidated. The new consolidation model for VIEs considers whether the Company has the power to direct the activities that most significantly impact the VIEs economic performance and shares in the significant risks and rewards of the entity. The guidance on VIEs requires companies to continually reassess VIEs to determine if consolidation is appropriate and provide additional disclosures. The guidance was effective for the beginning of the Company’s 2011 fiscal year. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. In January 2010, new guidance was issued to require new disclosures and clarify existing disclosure requirements about fair value measurements as set forth in the Fair Value Measurements and Disclosures Topic in the ASC. The guidance requires that a reporting entity should disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and describe the reasons for the transfers; and in the reconciliation for fair value measurements using significant unobservable inputs, a reporting entity should present separately information about purchases, sales, issuances, and settlements. In addition, the guidance clarifies that for purposes of reporting fair value measurement for each class of assets and liabilities, a reporting entity needs to use judgment in determining the appropriate classes of assets and liabilities; and a reporting entity should provide disclosures about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements. This guidance was effective for the Company as of the quarter ended March 31, 2010 except for the detailed level 3 roll forward disclosure, which is effective for fiscal years beginning after December 15, 2010. The adoption of this guidance will not have a material impact on the Company’s disclosures in its consolidated financial statements.

Income Taxes	9 Months Ended
Income Taxes	Jun. 30, 2011
Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes In determining the quarterly provision for income taxes, management uses an estimated annual effective tax rate which is based on the expected annual income and statutory tax rates in the various jurisdictions in which it operates. The Company’s effective tax rate differs from the U.S. statutory rate primarily due to state and local taxes, and differing statutory tax rates applied to the income of non-U.S. subsidiaries. The Company records the tax effect of certain discrete items, including the effects of changes in tax laws, tax rates and adjustments with respect to valuation allowances or other unusual or nonrecurring tax adjustments, in the interim period in which they occur, as an addition to, or reduction from, the income tax provision, rather than being included in the estimated effective annual income tax rate. In addition, jurisdictions with a projected loss for the year or a year-to-date loss where no tax benefit can be recognized are excluded from the estimated annual effective income tax rate. The Company is required to assess its deferred tax assets and the need for a valuation allowance at each reporting period. This assessment requires judgment on the part of management with respect to benefits that may be realized. The Company will record a valuation allowance against deferred tax assets when it is considered more likely than not that all or a portion of our deferred tax assets will not be realized. The income tax expense from continuing operations of $7.0 million and $4.8 million for the three months ended June 30, 2011 and 2010, respectively, and income tax expense from continuing operations of $17.1 million and $8.1 million for the nine months ended June 30, 2011 and 2010, respectively, reflect estimated federal, foreign and state taxes. For the three months ended June 30, 2011, the Company’s effective tax rate was 40%, compared to 36% for the three months ended June 30, 2010. For the nine months ended June 30, 2011, the Company's effective tax rate was 37%, compared to 36% for the nine months ended June 30, 2010. The Company and its subsidiaries file income tax returns with the U.S. federal jurisdiction and various state and foreign jurisdictions. The Internal Revenue Service has commenced an examination of the U.S. income tax return of FCStone Group, Inc. ("FCStone") for its fiscal year ended August 31, 2009. FCStone is a wholly-owned subsidiary acquired on September 30, 2009. Additionally, both INTL and FCStone are under separate state examinations for various periods, ranging from August 31, 2006 through September 30, 2009.

- Definition

The entire disclosure for income taxes.

Note 3 – Earnings per Share [Abstract]

Earnings Per Share [Text Block]

Earnings per Share

Basic earnings per share ("EPS") has been computed by dividing net income by the weighted-average number of common shares outstanding. The following is a reconciliation of the numerator and denominator of the diluted net income per share computations for the periods presented below.



	Three Months Ended June 30,					Nine Months Ended June 30,
(in millions, except share amounts)	2011		2010			2011		2010
Numerator:
Income from continuing operations attributable to INTL FCStone Inc. stockholders	$	10.4	$	8.6		$	29.6	$	14.8
Add: Interest on convertible debt, net of tax	0.2		0.2			0.5		—

Denominator:
Weighted average number of:
Common shares outstanding	17,901,613		17,335,362			17,714,916		17,293,058
Dilutive potential common shares outstanding:
Share-based awards	932,765		535,078			952,813		548,941

Diluted weighted-average shares	19,280,696		18,527,376			19,308,661		17,841,999

The dilutive effect of share-based awards is reflected in diluted net income per share by application of the treasury stock method, which includes consideration of unamortized share-based compensation expense required under the Compensation – Stock Compensation Topic of the ASC. The dilutive effect of convertible debt is reflected in diluted net income per share by application of the if-converted method.

Options to purchase 384,183 and 836,822 shares of common stock for the three months ended June 30, 2011 and 2010, respectively, and 391,031 and 836,822 shares of common stock for the nine months ended June 30, 2011 and 2010, respectively, were excluded from the calculation of diluted earnings per share because they would have been anti-dilutive.

The Company has unvested share-based payment awards that are considered participating securities and should be included in the computation of basic EPS using the two-class method. The Company has omitted disclosures related to the two-class method as the impact of the computation does not have a material effect on the condensed consolidated financial statements. Had the required disclosures been made for the three months ended June 30, 2011 and 2010, the Company’s basic EPS would have been reduced by less than $0.01 per share in each period, respectively. Had the required disclosures been made for the nine months ended June 30, 2011 and 2010, the Company’s basic EPS would have been reduced by less than $0.03 per share and $0.01 per share, respectively.

Receivables from customers and notes receivable, net

Receivables from customers and notes receivable, net [Abstract]

Financing Receivables [Text Block]

Receivables from customers and notes receivable, net

On June 30, 2011, the commodities market experienced downward limit price movements on certain commodities, and as a result, certain exchange-traded derivative contracts, which would normally be valued using quoted market prices were priced using a valuation model - see Note 6. These market events caused an increase in receivables from customers related to margin balances as of the balance sheet date. The Company has subsequently collected all margin balances from its customers related to these market events.

Receivables from customers, net and notes receivable, net include a provision for bad debts, which reflects our best estimate of probable losses inherent in the receivables from customers and notes receivable. The Company provides for an allowance for doubtful accounts based on a specific-identification basis. The Company continually reviews its provision for bad debts. The allowance for doubtful accounts related to receivables from customers is $12.1 million and $4.9 million at June 30, 2011 and September 30, 2010, respectively. The allowance for doubtful accounts related to total notes receivable was $0.1 million at June 30, 2011, and $114.3 million at September 30, 2010.

During the three and nine months ended June 30, 2011, the Company recorded bad debt expense, net of recoveries, of $1.2 million and $4.0 million, respectively. During the three and nine months ended June 30, 2011, increases to the allowance for doubtful accounts were $3.0 million and $7.5 million, respectively. The current provision increase was primarily related to an additional loss recognized on a customer to whom the Company had consigned gold, in the C&RM segment, for which a partial provision was recorded during the fourth quarter of fiscal 2010. During the three months ended June 30, 2011, negotiation efforts with the customer to partially settle the loss were unsuccessful, resulting in legal proceedings against the customer, and a charge to bad debt expense for the remainder of the loss in the amount of $2.7 million. During the nine months ended June 30, 2011, the provision increase also included amounts for another customer to whom the Company had consigned gold, in the C&RM segment, and a clearing customer deficit account in the CES segment. During the three and nine months ended June 30, 2011, the Company recorded recoveries of $1.8 million and $3.7 million, respectively, of bad debt expense. The current period recovery of $1.8 million related to a bad debt provision decrease on a previous customer account deficit, in the C&RM segment, based on a revision to the amount considered collectible. During the nine months ended June 30, 2011, recoveries also include $1.3 million following a settlement relating to a disputed trade that was “given-up” to FCStone during the quarter ended June 30, 2010 by another futures commission merchant ("FCM") for a customer that held an account with us.

As a result of the acquisition of FCStone, the Company acquired certain notes receivable of $133.7 million at September 30, 2009, consisting of promissory notes from certain customers and an introducing broker which arose from previous customer account deficits, of which the Company estimated collectability to be $16.7 million. During the three months ended March 31, 2011, the Company recovered $11.4 million as partial payment against the promissory notes receivable from these certain customers, and charged off $111.5 million against the allowance for notes receivable related to these certain customer account deficits. Total recoveries from these certain customers and introducing broker through June 30, 2011 is $12.8 million, and remaining notes receivable related to these certain customer account deficits is $3.9 million. Subsequent to June 30, 2011, the Company collected $2.6 million against the promissory notes. The Company expects to collect the remaining amounts from the introducing broker, by withholding commissions due on future revenues collected by the Company, although no assurance can be given as to the timing of collection.

Activity in the allowance for doubtful accounts and notes was as follows:



(in millions)
Balance, September 30, 2010	$	119.2
Provision for bad debts	7.5
Transfer in (1)	2.5
Deductions:

During the three months ended December 31, 2010, certain open position derivative contracts, which had a $2.5 million credit reserve at September 30, 2010 were closed, and the deficit account balance was reclassified from financial instruments owned to a receivable from customer. Accordingly, the previously established credit reserve amount was transferred into the allowance for doubtful accounts during the three months ended December 31, 2010.

Additionally, in the normal course of operations the Company accepts notes receivable under sale/repurchase agreements with customers whereby the customers sell certain commodity inventory and agree to repurchase the commodity inventory at a future date at either a fixed or floating rate. These transactions are short-term in nature, and are treated as secured borrowings rather than commodity inventory, purchases and sales in the Company’s condensed consolidated financial statements. At June 30, 2011 and September 30, 2010, the Company had outstanding notes receivable of $18.8 million and $13.6 million, respectively, related to this program

Exchange Memberships and Stock	9 Months Ended
Exchange Memberships and Stock	Jun. 30, 2011
Exchange Memberships and Stock [Abstract]
Exchange Memberships and Stock, [Text Block]	Exchange Memberships and Stock The Company holds certain commodity exchange membership seats and commodity exchange firm common stock, which are pledged for clearing purposes, providing the Company the right to process trades directly with the various exchanges. Exchange memberships and common stocks pledged for clearing purposes are recorded at cost. The Company acquired additional exchange firm common stock during the nine months ended June 30, 2011 at a cost of $3.4 million. In January 2011, excess shares of exchange firm common stock, with a cost basis of $1.2 million, were sold, resulting in a nominal gain. The cost basis for exchange memberships and common stock pledged for clearing purposes was $14.0 million and $11.9 million at June 30, 2011 and September 30, 2010, respectively, and is included within ‘other assets’ on the condensed consolidated balance sheets. The fair value of the exchange memberships and common stock pledged for clearing purposes was $13.3 million and $9.8 million at June 30, 2011 and September 30, 2010, respectively. The fair value of exchange stock is determined by quoted market prices, and the fair value of exchange memberships is determined by recent sale transactions. The Company monitors the fair value of exchange membership seats and common stock on a quarterly basis, and considers the current unrealized loss to be a temporary impairment.

Assets and Liabilities, at Fair Value [Abstract]

Fair Value Disclosures [Text Block]

Assets and Liabilities, at Fair Value

The Company’s financial and nonfinancial assets and liabilities reported at fair value are included within the following captions on the condensed consolidated balance sheets:


•	Cash and cash equivalents


•	Cash, securities and other assets segregated under federal and other regulations


•	Securities purchased under agreements to resell


•	Deposits and receivables from exchange-clearing organizations


•	Deposits and receivables from broker-dealers, clearing organizations and counterparties


•	Financial instruments owned


•	Accounts payable and other accrued liabilities


•	Payables to customers


•	Financial instruments sold, not yet purchased

The table below sets forth an analysis of the carrying value of financial instruments owned and financial instruments sold, not yet purchased. This is followed by tables that provide the information required by the Fair Value Measurements and Disclosures Topic of the ASC for all financial assets and liabilities that are carried at fair value.

Fair Value Hierarchy

The majority of financial assets and liabilities on the condensed consolidated balance sheets are reported at fair value. Cash and cash equivalents are reported at the balance held at financial institutions. Deposits with and receivables from exchange-clearing organizations and broker-dealers and FCMs and payables to customers and exchange-clearing organizations include the value of cash collateral as well as the value of money market funds and other pledged investments, primarily U.S. Treasury bills and obligations issued by government sponsored entities. These balances also include the fair value of futures and options on futures determined by prices on the applicable exchange. Financial instruments owned and sold, not yet purchased include the value of U.S. and foreign government obligations, corporate debt securities, derivative financial instruments, commodities, mutual funds and investments in managed funds. The fair value of exchange common stock is determined by quoted market prices, and the fair value of exchange memberships is determined by recent sale transactions. Notes payable and subordinated debt carry variable rates of interest and thus approximate fair value.

The following tables set forth the Company’s financial and nonfinancial assets and liabilities accounted for at fair value, on a recurring basis, as of June 30, 2011 and September 30, 2010 by level within the fair value hierarchy. There were no assets or liabilities that were measured at fair value on a nonrecurring basis as of June 30, 2011. As required by the Fair Value Measurements and Disclosures Topic of the ASC, financial and nonfinancial assets and liabilities measured on recurring and nonrecurring basis are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The three levels of the fair value hierarchy under the Fair Value Measurements and Disclosures Topic of the ASC are:

Level 1: unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2: quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and

Level 3: prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

In August 2008, INTL Asia Pte, Ltd., a subsidiary of the Company, arranged a 550 million Thai Baht ("THB"), an $18 million U.S. dollar ("USD") equivalent, issue of debentures for the single asset owning company of Suriwongse Hotel located in Chiang Mai, Thailand. The debentures have a 9.5% coupon and are scheduled to mature in August 2011. The Company arranged for the sale of 375.5 million THB ($12.6 USD) of the debentures to two investors and the Company retained debentures in the amount of 174.5 million THB ($5.4 USD). The debentures are secured by a mortgage on the land and hotel buildings, the personal guarantee of the owner, and conditional assignments of accounts and agreements.

The proceeds of this issue were to be used to refinance the previous loan to the hotel owner, finance the hotel's renovation and fund interest up to 50.0 million THB. Renovations were initially planned to be completed by April 2011 and the outstanding debentures were to be refinanced following the completion of renovations. The renovations have been delayed and are currently expected to be completed by February 2012.

In addition, the political and economic conditions in Thailand over the past two years have impacted the performance of the hotel. Following the interest capitalization period, the hotel owner was able to meet four quarterly interest payments on the debentures, however the hotel owner defaulted on the interest payment that was due in March 2011. The Company and other debenture holders are currently in restructuring discussions with the hotel owner as a result of the renovation delays.

In accordance with the Fair Value Measurements and Disclosures Topic of the ASC, the Company has estimated the fair value of the debentures on a recurring basis each period. At June 30, 2011, the Company's investment in the hotel is $3.6 million, and included within the corporate and municipal bonds classification in the level 3 financial assets and financial liabilities tables. The Company has classified its investment in the hotel within level 3 of the fair value hierarchy because the fair value is determined using significant unobservable inputs, which include projected cash flows. These cash flows are discounted employing present value techniques. During the nine months ended June 30, 2011, the Company recorded a loss of $1.7 million, representing an other than temporary impairment.

The Company is required to make additional future cash payments based on certain financial performance measures of its acquired businesses. The Company is required to remeasure the fair value of the cash earnout arrangements on a recurring basis in accordance with the guidance in the Business Combinations Topic of the ASC. The Company has classified its net liabilities for the contingent earnout arrangements within level 3 of the fair value hierarchy because the fair value is determined using significant unobservable inputs, which include projected cash flows. The estimated fair value of the contingent purchase consideration is based upon management-developed forecasts, a level 3 input in the fair value hierarchy. These cash flows are discounted employing present value techniques in arriving at the acquisition-date fair value. The discount rate was developed using market participant company data, a level 2 input in the fair value hierarchy, and there have been no significant changes in the discount rate environment. From the dates of acquisition to June 30, 2011, certain acquisitions have had changes in the estimates of undiscounted cash flows, based on actual performances fluctuating from estimates. During the three and nine months ended June 30, 2011, the fair value of the contingent consideration increased $0.3 million and $2.2 million, respectively, with the corresponding expense classified as 'other' within the condensed consolidated income statements.

The Company reports transfers in and out of levels 1, 2 and 3, as applicable, using the fair value of the securities as of the beginning of the reporting period in which the transfer occurred.

The value of an exchange-traded derivative contract is equal to the unrealized gain or loss on the contract determined by marking the contract to the current settlement price for a like contract on the valuation date of the contract. A settlement price may not be used if the market makes a limit move with respect to a particular derivative contract or if the securities underlying the contract experience significant price fluctuations after the determination of the settlement price. When a settlement price cannot be used, derivative contracts will be valued at their fair market value as determined in good faith pursuant to procedures adopted by management of the Company.

On June 30, 2011, the commodities market experienced downward limit price movements on certain commodities, and at March 31, 2011, the commodities market experienced upward limit price movements on certain commodities. As a result, certain exchange-traded derivative contracts, which would normally be valued using quoted market prices and classified as level 1 within the fair value hierarchy, were priced using a valuation model using observable inputs. Due to the change in valuation techniques because of the limit moves, derivative assets of $407.9 million and derivative liabilities of $256.3 million were classified as level 2 at June 30, 2011. Such derivative assets and liabilities were valued using quoted market prices, and as such, were classified as level 1 prior to March 31, 2011.

The Company did not have any additional significant transfers between level 1 and level 2 fair value measurements for the three months and nine months ended June 30, 2011.

The Company transferred $0.7 million of U.S. and foreign obligations from level 3 to level 2 during the nine months ended June 30, 2010. The Company re-evaluated the observability of the inputs for the fair value of the securities that were transferred into level 2 from level 3 and determined that there was improvement in the market for these securities and that resulted in the Company being able to utilize inputs that were observable.

There were no sales of AFS Securities during three and nine months ended June 30, 2011 and 2010, and as a result, no realized gains or losses were recorded for the three and nine months ended June 30, 2011 and 2010.

For the purposes of the maturity schedule, mortgage-backed securities, which are not due at a single maturity date, have been allocated over maturity groupings based on the expected maturity of the underlying collateral. Mortgage-backed securities may mature earlier than their stated contractual maturities because of accelerated principal repayments of the underlying loans.

Financial Instruments with Off-Balance Sheet Risk and Concentrations of Credit Risk [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

Financial Instruments with Off-Balance Sheet Risk and Concentrations of Credit Risk

The Company is party to certain financial instruments with off-balance sheet risk in the normal course of its business. The Company has sold financial instruments that it does not currently own and will therefore be obliged to purchase such financial instruments at a future date. The Company has recorded these obligations in the condensed consolidated financial statements at June 30, 2011 at the fair values of the related financial instruments. The Company will incur losses if the fair value of the underlying financial instruments increases subsequent to June 30, 2011. The total of $314.6 million at June 30, 2011 includes $116.0 million for derivative contracts, which represent a liability to the Company based on their fair values as of June 30, 2011.

Derivatives

The Company utilizes derivative products in its trading capacity as a dealer in order to satisfy client needs and mitigate risk. The Company manages risks from both derivatives and non-derivative cash instruments on a consolidated basis. The risks of derivatives should not be viewed in isolation, but in aggregate with the Company’s other trading activities. The majority of the Company’s derivative positions are included within the balance sheets under the caption ‘financial instruments owned, at fair value’, ‘deposits and receivables from exchange-clearing organizations’ and ‘financial instruments sold, not yet purchased, at fair value’.

The Company continues to employ an interest rate risk management strategy, implemented in April 2010, that uses derivative financial instruments in the form of interest rate swaps to manage a portion of the aggregate interest rate position. The Company’s objective is to invest the majority of customer segregated deposits in high quality, short-term investments and swap the resulting variable interest earnings into the medium-term interest stream, by using a strip of interest rate swaps that mature every quarter, in order to achieve the two year moving average of the two year swap rate. The risk mitigation of these interest rate swaps is not within the documented hedging designation requirements of the Derivatives and Hedging Topic of the ASC, and as a result they are recorded at fair value, with changes in the marked-to-market valuation of the financial instruments recorded within 'trading gains' in the condensed consolidated income statements on a quarterly basis.

Listed below are the fair values of the Company's derivative assets and liabilities as of June 30, 2011 and September 30, 2010. Assets represent net unrealized gains and liabilities represent net unrealized losses.

(1)	As of June 30, 2011 and September 30, 2010, the Company’s derivative contract volume for open positions was approximately 3.9 million and 3.5 million contracts, respectively.


(2)	In accordance with agreements with counterparties, the Company is allowed to periodically take advances against its open trade fair value. These amounts exclude advances against open trade fair value of $0.0 million and $27.0 million outstanding at June 30, 2011 and September 30, 2010, respectively.

The Company’s derivative contracts are principally held in its Commodities and Risk Management Services ("C&RM") segment. The Company assists its C&RM segment customers in protecting the value of their future production by entering into option or forward agreements with them on an OTC basis. The Company also provides its C&RM segment customers with sophisticated option products, including combinations of buying and selling puts and calls. The Company mitigates its risk by generally offsetting the customer's transaction simultaneously with one of the Company's trading counterparties or will offset that transaction with a similar but not identical position on the exchange. The risk mitigation of these offsetting trades is not within the documented hedging designation requirements of the Derivatives and Hedging Topic of the ASC. These derivative contracts are traded along with cash transactions because of the integrated nature of the markets for these products. The Company manages the risks associated with derivatives on an aggregate basis along with the risks associated with its proprietary trading and market-making activities in cash instruments as part of its firm-wide risk management policies. In particular, the risks related to derivative positions may be partially offset by inventory, unrealized gains in inventory or cash collateral paid or received.

The following table sets forth the Company's gains (losses) related to derivative financial instruments for the three and nine months ended June 30, 2011 and 2010, in accordance with the Derivatives and Hedging Topic of the ASC. The gains (losses) set forth below are included within ‘trading gains’ in the condensed consolidated income statements.



	Three Months Ended June 30,				Nine Months Ended June 30,
(in millions)	2011		2010		2011		2010
Gains (losses) from derivative contracts	$	33.2	$	10.8	$	6.8	$	(2.4	)

Periodically, the Company uses interest rate swap contracts to hedge certain forecasted transactions. The Company’s primary objective in holding these types of derivatives is to reduce the volatility of earnings and cash flows associated with changes in interest rates. The Company had one interest rate swap contract, with a notional amount of $50 million, mature during the three months ended June 30, 2011, and has one interest rate swap contract at June 30, 2011, with a notional amount of $50 million, which matures during July 2011. The interest rate swap contracts were entered into in order to hedge potential changes in cash flows resulting from the Company’s variable rate LIBOR based borrowings.

The interest rate swaps were initially classified under the Derivatives and Hedging Topic of the ASC as cash flow hedges. As a result of decreased borrowings by the Company in fiscal year 2010, it was determined that one of the interest rate swaps no longer met the criteria, specified under the Derivatives and Hedging Topic, to allow for the deferral of the effective portion of unrecognized hedging gains or losses in other comprehensive income or loss since all of the forecasted variable interest payments are not expected to occur. However, the Company expected that a portion of those forecasted transactions were still going to occur. As a result, the Company had a loss of $0.2 million, net of tax, as of December 31, 2010 remaining in accumulated other comprehensive income or loss relating to transactions that were still expected to occur for the discontinued hedge.

At December 31, 2010, the remaining unrecognized loss relating to both interest rate swaps in accumulated other comprehensive income (loss) was $0.6 million, net of tax. That amount was expected to be recognized in earnings as the forecasted payments affected interest expense. However, at the end of the three months ended March 31, 2011, the Company's borrowing levels decreased significantly and it was determined that the remaining swap no longer met the criteria for the deferral of the effective portion of unrecognized hedging gains or losses and the Company discontinued hedge accounting for the remaining swap. In addition, as the Company did not expect the borrowing levels to increase significantly before the swaps were due to mature, the remaining balances were recognized in earnings. The Company recognized a loss of $0.3 million, net of tax, for the nine months ended June 30, 2011, as a result of the discontinuation of hedge accounting which is included within ‘trading gains’ on the condensed consolidated income statements.

Credit Risk

In the normal course of business, the Company purchases and sells financial instruments, commodities and foreign currencies as either principal or agent on behalf of its customers. If either the customer or counterparty fails to perform, the Company may be required to discharge the obligations of the nonperforming party. In such circumstances, the Company may sustain a loss if the fair value of the financial instrument or foreign currency is different from the contract value of the transaction.

The majority of the Company’s transactions and, consequently, the concentration of its credit exposure are with commodity exchanges, customers, broker-dealers and other financial institutions. These activities primarily involve collateralized and uncollateralized arrangements and may result in credit exposure in the event that a counterparty fails to meet its contractual obligations. The Company’s exposure to credit risk can be directly impacted by volatile financial markets, which may impair the ability of counterparties to satisfy their contractual obligations. The Company seeks to control its credit risk through a variety of reporting and control procedures, including establishing credit limits based upon a review of the counterparties’ financial condition and credit ratings. The Company monitors collateral levels on a daily basis for compliance with regulatory and internal guidelines and requests changes in collateral levels as appropriate.

The Company is a party to financial instruments in the normal course of its business through customer and proprietary trading accounts in exchange-traded and OTC derivative instruments. These instruments are primarily the execution of orders for commodity futures, options on futures and forward foreign currency contracts on behalf of its customers, substantially all of which are transacted on a margin basis. Such transactions may expose the Company to significant credit risk in the event margin requirements are not sufficient to fully cover losses which customers may incur. The Company controls the risks associated with these transactions by requiring customers to maintain margin deposits in compliance with individual exchange regulations and internal guidelines. The Company monitors required margin levels daily and, therefore, may require customers to deposit additional collateral or reduce positions when necessary. The Company also establishes credit limits for customers, which are monitored daily. The Company evaluates each customer’s creditworthiness on a case by case basis. Clearing, financing, and settlement activities may require the Company to maintain funds with or pledge securities as collateral with other financial institutions. Generally, these exposures to both customers and exchanges are subject to master netting, or customer agreements, which reduce the exposure to the Company by permitting receivables and payables with such customers to be offset in the event of a customer default. Management believes that the margin deposits held at June 30, 2011 and September 30, 2010 were adequate to minimize the risk of material loss that could be created by positions held at that time. Additionally, the Company monitors collateral fair value on a daily basis and adjusts collateral levels in the event of excess market exposure. Generally, these exposures to both customers and counterparties are subject to master netting, or customer agreements which reduce the exposure to the Company.

The Company is also a party to a guarantee of payment and performance by a third party of an ethanol marketing agreement with a risk management customer which would require the Company to purchase the output of the customer if the third party could not perform under the marketing agreement. The guarantee does not have a set term, and the underlying agreement cannot be terminated by the third party unless the customer breaches the agreement. The maximum potential amount of future payments required under the guarantee cannot be estimated because the underlying marketing agreement does not specify the amount or the price of the ethanol to be purchased during the term of the agreement. The price of the ethanol to be purchased is at the discretion of the Company.

Derivative financial instruments involve varying degrees of off-balance sheet market risk whereby changes in the fair values of underlying financial instruments may result in changes in the fair value of the financial instruments in excess of the amounts reflected in the condensed consolidated balance sheets. Exposure to market risk is influenced by a number of factors, including the relationships between the financial instruments and the Company’s positions, as well as the volatility and liquidity in the markets in which the financial instruments are traded. The principal risk components of financial instruments include, among other things, interest rate volatility, the duration of the underlying instruments and changes in foreign exchange rates. The Company attempts to manage its exposure to market risk through various techniques. Aggregate market limits have been established and market risk measures are routinely monitored against these limits.

Credit Facilities [Abstract]

Debt Disclosure [Text Block]

Credit Facilities

As of June 30, 2011, the Company had four credit facilities under which the Company may borrow up to $365.0 million, subject to certain conditions. The amounts outstanding under these credit facilities are short term borrowings and carry variable rates of interest, thus approximating fair value.

A summary of the Company’s credit facilities in place at June 30, 2011 is as follows:

•

A one-year, renewable, revolving syndicated committed loan facility expiring on September 21, 2011 under which the Company’s subsidiary, INTL Commodities, Inc. ("INTL Commodities") is entitled to borrow up to $140 million, subject to certain conditions. The loan proceeds are used to finance the activities of INTL Commodities and are secured by its assets. The facility is guaranteed by the Company, and the Company is currently in discussions with the lender and expects to renew the facility during the fourth quarter of fiscal 2011.


•	A three-year syndicated committed loan facility established on October 29, 2010 under which the Company is entitled to borrow up to $75 million, subject to certain conditions. The loan proceeds are used to finance working capital needs of the Company and certain subsidiaries.


•	An unsecured committed line of credit, expiring June 18, 2012, with a syndicate of lenders under which the Company’s subsidiary, FCStone, LLC may borrow up to $75 million. This line is intended to provide short term funding of margin to commodity exchanges as necessary. The line is subject to annual review.


•	A one-year committed borrowing facility with a syndicate of lenders expiring on December 1, 2011 under which the Company’s subsidiary, FCStone Financial, Inc. is entitled to borrow up to $75 million, subject to certain conditions. The loan proceeds are used to finance traditional commodity financing arrangements.

The Company’s credit facilities and outstanding borrowings, including subordinated debt, as of June 30, 2011 and September 30, 2010 were as follows:



(in millions)				Amounts Outstanding
Security	Renewal / Expiration Date	Total Commitment		June 30, 2011		September 30, 2010

None	Terminated December 2010	—		—		0.5
		$	365.0	$	120.5	$	115.4

During the fourth quarter of fiscal 2011, $140 million of the Company’s committed credit facilities are scheduled to expire. While there is no guarantee that the Company will be able to replace current agreements when they expire, based on a strong liquidity position and capital structure the Company believes it will be able to do so.

The Company’s facility agreements contain covenants relating to financial measures such as minimum net worth, minimum working capital, minimum regulatory capital, minimum cumulative EBITDA and minimum interest coverage ratios. Failure to comply with any such covenants could result in the debt becoming payable on demand. As of June 30, 2011 the Company was in compliance with all of its covenants under its credit facilities.

Convertible Subordinated Notes	9 Months Ended
Convertible Subordinated Notes	Jun. 30, 2011
Convertible Subordinated Notes [Abstract]
Subordinated Borrowings Disclosure [Text Block]	Convertible Subordinated Notes The Company had $9.0 million and $16.7 million in aggregate principal amount of the Company’s senior subordinated convertible notes due September 2011 (the "Notes") outstanding as of June 30, 2011 and September 30, 2010, respectively. The Notes are general unsecured obligations of the Company and bear interest at the rate of 7.625% per annum, payable quarterly in arrears. During the nine months ended June 30, 2011, holders of $7.7 million in principal amount of the Notes converted the principal and accrued interest of $0.1 million into 359,235 shares of common stock of the Company. As of June 30, 2011, the remaining Notes are convertible by the holders into 413,034 shares of common stock of the Company at a conversion price of $21.79 per share. If the dollar-volume weighted-average price of the common stock exceeds $38.25 per share, subject to certain adjustments, for any twenty out of thirty consecutive trading days, the Company will have the right to require the holders of the Notes to convert all or any portion of the Notes into shares of common stock at the then-applicable conversion price. In the event that the consolidated net interest coverage ratio, as set forth in the Notes, for the 12 months preceding the end of any fiscal quarter is less than 2.0, the interest rate on the Notes will be increased by 2.0% to 9.625% per annum, effective as of the first day of the following fiscal quarter. Through the quarter ended June 30, 2011, the consolidated net interest coverage ratio has exceeded 2.0 and no such increase has been necessary. The Company entered into a separate Registration Rights Agreement with the holders of the Notes, under which the Company was required to file with the SEC a Registration Statement on Form S-3 within a specified period of time. The Registration Statement was declared effective by the SEC on October 24, 2006. The Company is required, under the Registration Rights Agreement, to maintain the effectiveness of the Registration Statement, failing which it could become liable to pay holders of the Notes liquidated damages of 1% of the value of the Notes, plus a further 1% for every 30 days that it remains ineffective thereafter, up to an aggregate maximum of 10% of the value of the Notes. At June 30, 2011 the Company was in compliance with its requirements under the Registration Rights Agreement.

Commitments and Contingencies	9 Months Ended
Commitments and Contingencies	Jun. 30, 2011
Commitments and Contingencies [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Commitments and Contingencies Legal Proceedings Securities Litigation FCStone and certain officers of FCStone were named as defendants in an action filed in the United States District Court for the Western District of Missouri on July 15, 2008. A consolidated amended complaint ("CAC") was subsequently filed on September 25, 2009. As alleged in the CAC, the action purports to be brought as a class action on behalf of purchasers of FCStone common stock between November 15, 2007 and February 24, 2009. The CAC seeks to hold defendants liable under Section 10(b) and Section 20(a) of the Securities Exchange Act of 1934 and concerns disclosures included in FCStone's fiscal year 2008 public filings. Specifically, the CAC relates to FCStone's public disclosures regarding an interest rate hedge, a bad debt expense arising from unprecedented events in the cotton trading market, and certain disclosures beginning on November 3, 2008 related to losses it expected to incur arising primarily from a customer energy trading account. FCStone and the named officers moved to dismiss the action. Although the Court denied that motion on November 16, 2010, it limited the action to the public disclosures made on November 3 and 4, 2008 related to the energy trading account. As a result of the Court's order and lead plaintiffs' decision not to amend their complaint, the lead plaintiffs lost standing to prosecute the action because they were not shareholders at the relevant time. Counsel for lead plaintiffs have since added named plaintiffs who purport to possess standing. Currently pending before the Court is Defendants' motion as to whether the Private Securities Litigation Reform Act of 1995 requires supplemental notice in order for the action to proceed. The Company and the FCStone defendants continue to believe the action is meritless, and intend to defend the action vigorously. In August 2008, a shareholder derivative action was filed against FCStone and certain directors of FCStone in the Circuit Court of Platte County, Missouri, alleging breaches of fiduciary duties, waste of corporate assets and unjust enrichment. An amended complaint was subsequently filed in May 2009 to add claims based upon the losses sustained by FCStone arising out of a customer's energy trading account. On July 7, 2009, the same plaintiff filed a motion for leave to amend the existing case to add a purported class action claim on behalf of the holders of FCStone common stock. On July 8, 2009, a purported shareholder class action complaint was filed against FCStone and its directors, as well as the Company in the Circuit Court of Clay County, Missouri. The complaint alleged that FCStone and its directors breached their fiduciary duties by failing to maximize stockholder value in connection with the contemplated acquisition of FCStone by the Company. This complaint was subsequently consolidated with the complaint filed in the Circuit Court of Platte County, Missouri. The plaintiffs subsequently filed an amended consolidated complaint which does not assert any claims against the Company. This complaint purports to be filed derivatively on FCStone and the Company's behalf and against certain of FCStone current and former directors and officers and directly against the same individuals. The Company, FCStone, and the defendants filed motions to dismiss on multiple grounds. That motion is fully briefed and pending decision. As previously discussed, the staff of the Fort Worth Regional Office of the SEC is conducting a formal investigation of FCStone's disclosures and accounting for losses associated with the energy trading account, which occurred prior to the Company's acquisition of FCStone on September 30, 2009. During the quarters ended March 31, 2011 and June 30, 2011, certain employees of the Company testified before the SEC in connection with this investigation. The Company is cooperating fully with the SEC staff in its investigation, but cannot predict the scope, duration or outcome of the matter. On February 24, 2011, the Company's Board of Directors formed a special committee to conduct an independent investigation of FCStone's disclosures and accounting for losses associated with the energy trading account. The Company's Board of Directors determined that it would be appropriate and consistent with its governance and oversight responsibilities to form the special committee to investigate these matters as they pertain to the private litigation and the SEC investigation described above. The special committee, which is comprised solely of independent directors of the Company who were not formerly directors of FCStone, has retained an independent law firm to represent and assist it in its review. Convertible Note Holder Litigation On October 20, 2010, three investors in the Company's senior subordinated convertible notes due September 2011 (the “Notes”), consisting of Highbridge International LLC, LBI Group Inc. and Iroquois Master Fund Ltd., filed suit against the Company, claiming that the acquisition by the Company of FCStone in September 2009 resulted in a change of control as defined in the Notes and that, as a result, the Company should have afforded them the opportunity to have the Notes redeemed at a 15% premium. The investors also claimed the right to penalty interest at the rate of 15% per annum established in the Notes. The investors held Notes with a principal amount of $13.0 million at the time of the commencement of the litigation. On April 21, 2011 the Company's motion to dismiss the investors' lawsuit was denied. Accordingly, the lawsuit is expected to proceed to trial, with discovery expected during summer and fall of 2011. Prior to April 21, 2011, one of the investors, Iroquois Master Fund Ltd., converted $3.0 million of its $4.0 million investment in principal amount of the Notes, and accrued interest, into 139,136 shares of common stock of the Company. On April 25, 2011, Iroquois Master Fund Ltd. converted the remaining $1.0 million of its original $4 million investment in the Notes, leaving $9.0 million in principal amount of the Notes outstanding as of June 30, 2011. During July 2011, LBI Group Inc. sold its entire $5 million investment in principal amount of the Notes to Leucadia National Corporation (the holder of approximately 8% of the outstanding common stock of the Company), filed a stipulation of discontinuance in the aforementioned lawsuit and released the Company from any further claims in connection with its prior investment in the Notes. Sentinel Litigation On January 21, 2011 the bankruptcy trustee of Sentinel Management Group, Inc. filed a motion for summary judgment against one of the Company's subsidiaries, FCStone, LLC, on various counts in the adversary proceedings filed in August 2008 against FCStone, LLC and a number of other FCMs. The nature of these adversary proceedings has been disclosed in previous filings of the Company. FCStone, LLC filed its response on May 10, 2011. Apart from the above, there have been no material developments in previously reported litigation, and no other reportable events have occurred during the quarter ended June 30, 2011 or through the date of this filing. Contractual Commitments Contingent Liabilities - Acquisitions The Company has a contingent liability relating to the acquisition of Hencorp Becstone Futures, L.C., which was renamed INTL Hencorp Futures, LLC ("Hencorp Futures"), which occurred during the first quarter of 2011, which may result in the payment of additional consideration – see Note 16. The acquisition date fair value of additional consideration is remeasured to its fair value each quarter, with changes in fair value recorded in current earnings. The change in fair value for the three and nine months ended June 30, 2011 was an increase of $0.1 million and $0.3 million, respectively, and is included within ‘other expense’ in the condensed consolidated income statements. The present value of the estimated total purchase price, including contingent consideration, is $6.2 million at June 30, 2011, of which $2.5 million has not been paid and is included within ‘accounts payable and other liabilities’ in the condensed consolidated balance sheets. The Company has a contingent liability relating to the acquisition of the Hanley Companies, which occurred during the fourth quarter of 2010, which may result in the payment of additional consideration. The acquisition date fair value of additional consideration is remeasured to its fair value each quarter, with changes in fair value recorded in current earnings. The change in fair value for the three and nine months ended June 30, 2011 was an increase of $1.8 million and $3.6 million, respectively, and is included within ‘other expense’ in the condensed consolidated income statements. The present value of the estimated total purchase price, including contingent consideration, is $50.9 million at June 30, 2011, of which $19.2 million has not been paid and is included within ‘accounts payable and other liabilities’ in the condensed consolidated balance sheets. The Company has a contingent liability relating to the acquisition of the RMI Companies, which occurred during the third quarter of 2010, which may result in the payment of additional consideration. The acquisition date fair value of additional consideration is remeasured to its fair value each quarter, with changes in fair value recorded in current earnings. The change in fair value for the three and nine months ended June 30, 2011 was a decrease of $1.6 million, respectively, and is included within ‘other expense’ in the condensed consolidated income statements. The present value of the estimated total purchase price, including contingent consideration, is $15.1 million at June 30, 2011, of which $6.0 million has not been paid and is included within ‘accounts payable and other liabilities’ in the condensed consolidated balance sheets. The Company had a contingent liability relating to the acquisition of Compania Inversora Bursatil S.A. Sociedad de Bolsa. The Company paid approximately $1.7 million on the date of purchase and was obligated to make additional payments, depending on the level of revenues achieved. Under the purchase agreement, the Company was obligated to pay an amount equal to 25% of the net revenues if such net revenues are in excess of $2.5 million and up to $3.0 million, 35% of the net revenues in excess of $3.0 million and up to $4.0 million, and 40% of the net revenues in excess of $4.0 million for each of the two twelve-month periods ending March 31, 2010 and 2011 to the sellers as additional consideration. The net revenues for the twelve-month period ended March 31, 2011 were below the minimum target, so no further amounts will be paid. Convertible Subordinated Notes As discussed in Note 12 – Convertible Subordinated Notes, the Notes may be converted into shares of common stock of the Company at any time by the holders. The Notes also contain a provision to increase the interest rate by 2%, subject to certain conditions measured on a quarterly basis. Exchange Member Guarantees The Company is a member of various exchanges that trade and clear futures and option contracts. Associated with its memberships, the Company may be required to pay a proportionate share of the financial obligations of another member who may default on its obligations to the exchanges. While the rules governing different exchange memberships vary, in general the Company’s guarantee obligations would arise only if the exchange had previously exhausted its resources. In addition, any such guarantee obligation would be apportioned among the other non-defaulting members of the exchange. Any potential contingent liability under these membership agreements cannot be estimated. The Company has not recorded any contingent liability in the condensed consolidated financial statements for these agreements and believes that any potential requirement to make payments under these agreements is remote. Impairment The Company recorded an impairment charge of $0.7 million in the first quarter of 2010 in connection with INTL Sieramet LLC, a corporation in which it holds a 55% equity interest. This amount is recorded within ‘bad debts and impairments’ in the condensed consolidated income statements for the nine months ended June 30, 2010. The impairment charge recognizes the pending liquidation of INTL Sieramet and the probability that there may be incomplete recovery of the full value of its assets. Change in Control Contingency In connection with the acquisition of FCStone, certain of FCStone’s management and executive officers are participants in FCStone’s Change in Control Severance Plan (the “Severance Plan"). The Severance Plan provides that if during the two-year period following the completion of the merger agreement, a participant terminates their employment for “good reason” or the Company terminates the participant’s employment other than for “cause” or on account of death or disability, the Company will be committed to pay certain compensation amounts to the participant in a lump sum amount. The maximum potential commitment for all participants is $4.5 million. At June 30, 2011, no actions have occurred or are anticipated which would trigger payments under the Severance Plan.

Stock-Based Compensation

9 Months Ended

Jun. 30, 2011

Stock-Based Compensation [Abstract]

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]

Stock-Based Compensation

Stock-based compensation expense is included within compensation and benefits in the condensed consolidated income statements and totaled $0.5 million and $0.6 million for the three months ended June 30, 2011 and 2010, respectively and $1.6 million and $1.4 million for the nine months ended June 30, 2011 and 2010, respectively.

Stock Option Plans

The Company sponsors a stock option plan for its directors, officers, employees and consultants. At June 30, 2011, 744,481 shares were authorized for future grant under this plan. Awards that expire or are canceled generally become available for issuance again under the plan. We settle stock option exercises with newly issued shares of common stock.

Fair value is estimated at the grant date based on a Black-Scholes-Merton option-pricing model using the following weighted-average assumptions:



	Nine Months Ended June 30,
	2011		2010
Expected stock price volatility	77	%	85	%
Expected dividend yield	—	%	—	%
Risk free interest rate	0.72	%	1.46	%
Average expected life (in years)	2.94		2.80

Expected stock price volatility rates are based on the historical volatility of the Company’s common stock. The Company has not paid dividends in the past and does not currently expect to do so in the future. Risk free interest rates are based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option or award. The average expected life represents the estimated period of time that options or awards granted are expected to be outstanding, based on the Company’s historical share option exercise experience for similar option grants.

The following is a summary of stock option activity through June 30, 2011:



	Shares Available for Grant		Number of Options Outstanding		Weighted Average Price		Weighted Average Grant Date Fair Value		Weighted Average Remaining Term (in years)	Aggregate Intrinsic Value ($ millions)
Balances at September 30, 2010	744,871		1,476,500		$	20.42	$	8.93	3.68	$	8.4
Granted	(51,323	)	51,323		$	23.46	$	11.66
Exercised			(122,474	)	$	11.17	$	7.71
Forfeited	4,333		(4,333	)	$	24.48	$	10.81
Expired	46,600		(46,600	)	$	28.81	$	14.43
Balances at June 30, 2011	744,481		1,354,416		$	21.07	$	8.94	3.29	$	13.1
Exercisable at June 30, 2011			852,482		$	27.95	$	11.66	3.27	$	5.7

The total compensation cost not yet recognized for non-vested awards of $1.3 million at June 30, 2011 has a weighted-average period of 2.32 years over which the compensation expense is expected to be recognized. The total intrinsic value of options exercised during the nine months ended June 30, 2011 and 2010 was $1.6 million and $1.4 million, respectively.

Restricted Stock Plan

The Company sponsors a restricted stock plan for its directors, officers and employees. At June 30, 2011, 326,535 shares were authorized for future grant under our restricted stock plan. Awards that expire or are canceled generally become available for issuance again under the plan. The Company settles restricted stock with newly issued shares of common stock.

The following is a summary of restricted stock activity through June 30, 2011:



	Shares Available for Grant		Number of Shares Outstanding		Weighted Average Grant Date Fair Value		Weighted Average Remaining Term (in years)	Aggregate Intrinsic Value ($ millions)
Balances at September 30, 2010	430,882		240,368		$	13.66	2.13	$	4.4
Granted	(104,347	)	104,347		$	24.05
Vested			(77,469	)	$	16.78
Balances at June 30, 2011	326,535		267,246		$	16.81	2.04	$	6.5

The total compensation cost not yet recognized of $3.5 million at June 30, 2011 has a weighted-average period of 2.04 years over which the compensation expense is expected to be recognized. Compensation expense is amortized on a straight-line basis over the vesting period. Restricted stock grants are included in the Company’s total issued and outstanding common shares.

Acquisitions	9 Months Ended
Acquisitions	Jun. 30, 2011
Acquisitions [Abstract]
Business Combination Disclosure [Text Block]	Acquisitions On October 1, 2010, the Company acquired all of the ownership interests in Hencorp Futures, the commodity futures operation of Miami-based Hencorp Becstone. Hencorp Futures specializes in the development and execution of risk-management programs designed to hedge price volatility in a number of widely traded commodities, including coffee, sugar, cocoa, grains and energy products. The transaction will enable the Company to round out its portfolio of commodity risk management services to include a more robust capability in soft commodities, especially coffee, where Hencorp Futures has established a substantial presence and reputation globally, and especially in Central and South America. The acquisition of Hencorp Futures is not significant on an individual basis, and the purchase price consisted of an initial payment of $2.3 million, two payments totaling $1.4 million, representing the adjusted tangible equity of Hencorp Futures as of September 30, 2010, four contingent payments which will be based on Hencorp Futures’ net income for each of the four years after the closing and a final contingent payment based on the average net income of the second, third and fourth years. The present value of the estimated total purchase price, including contingent consideration, at the acquisition date was $6.0 million. The Company has made a preliminary allocation of the purchase costs among tangible assets, identified intangible assets with determinable useful lives, intangible assets with indefinite lives and goodwill. The preliminary intangible assets and goodwill recognized in this transaction were assigned to the C&RM segment. The Company is in the process of finalizing third-party valuations of the intangible assets and contingent liabilities. Purchase costs allocated to intangible assets with determinable useful lives are $1.7 million, which will be amortized over the remaining useful lives of the assets, and include customer relationships of $1.3 million (twenty-year weighted-average useful life) and non-compete agreements of $0.4 million (two-year weighted-average useful life). Purchase costs allocated to intangible assets with indefinite lives are $0.8 million, and relate to a trade name. Goodwill of $2.1 million has been calculated as the excess of the fair value of the consideration transferred over the fair value of the identified net assets acquired and liabilities assumed, and is expected to be deductible for tax purposes. Under the terms of the purchase agreements, the Company has obligations to pay additional consideration if specific conditions and earnings targets are met, as described above. In accordance with the Business Combinations Topic of the ASC, the fair value of the additional consideration is recognized as a contingent liability as of the acquisition date. The acquisition date fair value of additional consideration was estimated to be $2.3 million. The contingent liability for the estimated additional consideration is included in the ‘accounts payable and other accrued liabilities’ caption of the condensed consolidated balance sheet at June 30, 2011. The contingent liability recorded represents the fair value of the expected consideration to be paid based on the forecasted sales during the four year period and a discount rate being applied to those future payments. At the end of each reporting period after the acquisition date, the contingent payment will be remeasured to its fair value, with changes in fair value recorded in current earnings - see Note 13. The Company’s consolidated financial statements include the operating results of Hencorp Futures from the date of acquisition. Effective April 15, 2011, the Company entered into an agreement with Hudson Capital Energy LLC ("HCEnergy"), a New York-based energy risk-management firm, to acquire certain assets from HCEnergy. The transaction enables INTL's energy risk management services to include a more robust capability in crude oil and refined products. HCEnergy is a specialist in exchange cleared options, swaps and futures, and has grown its business to include hedging and trading professionals across the spectrum of global petroleum products. The acquisition of certain assets from HCEnergy is not significant on an individual basis, and the purchase price consideration included the aggregate net asset value of certain commodity futures brokerage accounts and certain proprietary software, totaling $1.0 million. At June 30, 2011, the consideration has not been paid, and is included within 'accounts payable and other liabilities' in the condensed consolidated balance sheets. There was no contingent consideration associated with this transaction, and it is not considered to be material to the consolidated financial statements.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Segment Analysis

9 Months Ended

Jun. 30, 2011

Segment Analysis [Abstract]

Segment Reporting Disclosure [Text Block]

Segment Analysis

The Company reports its operating segments based on services provided to customers. The Company’s activities are divided into the following five functional areas:


•	Commodity and Risk Management Services


•	Foreign Exchange


•	Securities


•	Clearing and Execution Services


•	Other

To conform to the current quarterly presentation, the Company has reclassified certain prior period segment total asset amounts. On a periodic basis, the Company sweeps excess cash from operating segments to a centralized corporate treasury function in exchange for an intercompany receivable asset. The intercompany receivable asset is eliminated during consolidation, and therefore this practice may impact reported total assets between segments.

Commodity and Risk Management Services (C&RM)

The Company serves its commercial customers through its force of approximately 155 risk management consultants with a high value added service that differentiates us from other competitors and maximizes the opportunity to retain customers. The Integrated Risk Management Program ("IRMP®") involves providing customers with commodity risk management consulting services that are designed to develop a customized long term hedging program to help them mitigate their exposure to commodity price risk and maximize the amount and certainty of their operating profits. Customers are assisted in the execution of their hedging strategies through the Company’s exchange-traded futures and options clearing and execution operations and through access to more customized alternatives provided by the OTC trading desk. Generally, customers direct their own trading activity and risk management consultants do not have discretionary authority to transact trades on behalf of customers. When transacting OTC contracts with customers, the Company may offset the customer’s transaction simultaneously with one of its trading counterparties. Alternatively, the OTC trade desk will accept a customer transaction and offset that transaction with a similar but not identical position on the exchange.

In addition, the Company provides a full range of trading and hedging capabilities to select producers, consumers, recyclers and investors in precious metals and certain base metals. Acting as a principal, the Company commits its own capital to buy and sell the metals on a spot and forward basis.

The Company records its physical commodities revenues on a gross basis. Operating revenues and losses from the Company’s commodities derivatives activities are included within ‘trading gains’ in the condensed consolidated income statements. Inventory for the commodities business is valued at the lower of cost or fair value under the provisions of the Inventory Topic of the ASC. The Company generally mitigates the price risk associated with commodities held in inventory through the use of derivatives. The Company does not elect hedge accounting under U.S. GAAP in accounting for this price risk mitigation. In such situations, unrealized gains in inventory are not recognized under U.S. GAAP, but unrealized gains and losses in related derivative positions are recognized under U.S. GAAP. As a result, the Company’s reported earnings from commodities trading may be subject to significant volatility when calculated under U.S. GAAP.

Foreign Exchange

The Company provides treasury, global payment and foreign exchange services to financial institutions, multi-national corporations, government organizations and charitable organizations as well as assisting commercial customers with the execution of foreign exchange hedging strategies. The Company transacts in over 130 currencies and specializes in smaller, more difficult emerging markets where there is limited liquidity. In addition, the Company executes trades based on the foreign currency flows inherent in the Company’s existing business activities. The Company primarily acts as a principal in buying and selling foreign currencies on a spot basis. The Company derives revenue from the difference between the purchase and sale prices.

The Company also provides spot foreign currency trading for a customer base of eligible contract participants and high net worth retail customers as well as operating a proprietary foreign exchange desk which arbitrages the futures and cash markets.

Securities

Through INTL Trading, the Company acts as a wholesale market maker in select foreign securities including unlisted ADRs and foreign ordinary shares. INTL Trading provides execution and liquidity to national broker-dealers, regional broker-dealers and institutional investors.

The Company also originates, structures and places a wide array of emerging market debt instruments in the international and domestic capital markets. These instruments include complex asset backed securities, unsecured bond and loan issues, negotiable notes and other trade-related debt instruments used in cross-border trade finance. On occasions the Company may invest its own capital in debt instruments before selling them. It also actively trades in a variety of international debt instruments.

Clearing and Execution Services (CES)

The Company seeks to provide competitive and efficient clearing and execution of exchange-traded futures and options for the institutional and professional trader market segments. Through its platform, customer orders are accepted and directed to the appropriate exchange for execution. The Company then facilitates the clearing of customers’ transactions. Clearing involves the matching of customers’ trades with the exchange, the collection and management of margin deposits to support the transactions, and the accounting and reporting of the transactions to customers. The Company seeks to leverage its capabilities and capacity by offering facilities management or outsourcing solutions to other FCMs.

Other

This segment consists of the Company’s asset management and commodity financing and facilitation business. The asset management revenues include fees, commissions and other revenues received by the Company for management of third party assets and investment gains or losses on the Company’s investments in funds and proprietary accounts managed either by the Company’s investment managers or by independent investment managers.

The Company operates a commodity financing and facilitation business which provides financing to commercial commodity-related companies against physical inventories, including grain, lumber, meats, energy products and renewable fuels. Sale and repurchase agreements are used to purchase commodities evidenced by warehouse receipts, subject to a simultaneous agreement to sell such commodities back to the original seller at a later date. These transactions are accounted for as product financing arrangements, and accordingly no commodity inventory, purchases or sales are recorded.

The total revenues reported combine gross revenues for the physical commodities business and net revenues for all other businesses. In order to reflect the way that the Company’s management views the results, the tables below also reflect the segmental contribution to ‘operating revenues’, which is shown on the face of the condensed consolidated income statements and which is calculated by deducting physical commodities cost of sales from total revenues.

Segment data includes the profitability measure of net contribution by segment. Net contribution is one of the key measures used by management to assess the performance of each segment and for decisions regarding the allocation of the Company’s resources. Net contribution is calculated as revenue less direct cost of sales, clearing and related expenses, variable compensation, introducing broker commissions and interest expense. Variable compensation paid to traders generally represents a fixed percentage of an amount equal to revenues generated, and in some cases, revenues produced less clearing and related charges, base salaries and an overhead allocation.

The segment data also includes segment income which is calculated as net contribution less certain non-variable direct expenses of the segment. These non-variable direct expenses include trader base compensation and benefits, operational employee compensation and benefits, communication and data services, travel, professional fees, bad debt expense and other direct expenses.

Inter-segment revenues, charges, receivables and payables are eliminated upon consolidation, except revenues and costs related to foreign currency transactions undertaken on an arm’s length basis by the foreign exchange trading business for the securities business. The foreign exchange trading business competes for this business as it does for any other business. If its rates are not competitive, the securities businesses buy or sell their foreign currency through other market counter-parties.

Information concerning operations in these segments of business is shown in accordance with the Segment Reporting Topic of the ASC as follows:

Extraordinary Item	9 Months Ended
Extraordinary Item	Jun. 30, 2011
Extraordinary item [Abstract]
Extraordinary Items Disclosure [Text Block]	On September 30, 2009, the Company acquired FCStone through the issuance of 8,239,319 shares of the Company’s common stock. The allocation of purchase price to assets acquired and liabilities assumed as of the date of acquisition resulted in negative goodwill of $18.5 million which was recognized as an extraordinary item in the Company’s consolidated income statement for the fiscal year ended September 30, 2009. During the three months ended December 31, 2009, management revised the estimate of state tax allocations resulting in a reduction in the consolidated effective state tax rate. As a result, the net deferred tax assets decreased by $3.4 million, including a change in estimate related to the valuation of state net operating loss carryforwards. The Company’s change in estimate was the result of revised revenue apportionment factors in certain jurisdictions due to analysis and activities completed subsequent to the filing of the fiscal year ended September 30, 2009 financial statements. Typically, changes within the measurement period that result from new information about facts and circumstances that existed at the acquisition date are recognized through a corresponding adjustment to goodwill. However, in the absence of goodwill recorded in connection with this transaction, the $3.4 million decrease in net deferred tax assets has been reported as an extraordinary loss in the condensed consolidated income statement for the nine months ended June 30, 2010. During January 2010, the Company paid $1.2 million in additional consideration related to a pre-acquisition contingency that was reported as a $0.8 million extraordinary loss, net of taxes, in the condensed consolidated income statement for the nine months ended June 30, 2010. During the three months ended June 30, 2010, the Company identified an accounting error related to the recording of goodwill in the amount of $0.8 million, net of tax that occurred solely within the first quarter of 2010. The error arose due to the incorrect interpretation and application of authoritative accounting literature related to accounting for pre-acquisition contingencies. The Company evaluated materiality under the guidance of SEC Staff Accounting Bulletin No. 99, Materiality, and considered relevant qualitative and quantitative factors. Based on this analysis, the Company corrected the error through the recognition of a purchase price adjustment in the amount of $0.8 million, net of tax, reported as an extraordinary loss in the condensed consolidated income statement for the three months ended June 30, 2010, and a corresponding $0.8 million, net of tax decrease in goodwill and intangible assets reported on the condensed consolidated balance sheet at June 30, 2010. The Company’s analysis supports the conclusion that this error was not material to that quarter or any prior periods impacted by the error.

Subsequent Events	9 Months Ended
Subsequent Events	Jun. 30, 2011
Subsequent Events [Abstract]
Subsequent Events [Text Block]	Subsequent Events On April 7, 2011, the Company's wholly-owned subsidiary in the United Kingdom, INTL Global Currencies Limited, agreed to acquire the issued share capital of Ambrian Commodities Limited (“Ambrian”), the London Metals Exchange brokerage subsidiary of Ambrian Capital Plc. On August 5, 2011, the Financial Services Authority granted its approval of the change of control of Ambrian. Completion of the transaction is expected to take effect on August 31, 2011. The purchase consideration will be equal to net asset value ("NAV") of Ambrian, which is estimated to be $17.0 million. The Company will pay 75 percent of the estimated NAV upon completion of the transaction, with the balance being paid ten days after completion of a closing balance sheet audit. The acquisition is not expected to have any immediate impact on the Company's earnings. This transaction is not considered to be material. Ambrian, currently a non-clearing LME member, specializes in the development and execution of risk-management programs designed to hedge price fluctuations in base metals for a wide variety of producers, manufacturers and fabricators. Ambrian has a niche focus on smaller industrial clients, including lead recyclers, brass producers, zinc galvanizers, metal refineries and copper foil producers that use LME futures and options for hedging raw material costs or output prices.
