Nature Of Operations And Basis Of Presentation	'
	NOTE 1 – Nature of Operations and Basis of Presentation
	Nature of Operations
	Stifel Financial Corp.  (the “Parent”), through its wholly owned subsidiaries, principally Stifel, Nicolaus & Company, Incorporated (“Stifel”), Stifel Bank & Trust (“Stifel Bank”), Stifel Nicolaus Europe Limited (“SNEL”), Century Securities Associates, Inc. (“CSA”), Keefe, Bruyette & Woods, Inc. (“KBW”), Keefe, Bruyette & Woods Limited (“KBW Limited”), and Miller Buckfire & Co. LLC (“Miller Buckfire”), is principally engaged in retail brokerage; securities trading; investment banking; investment advisory; retail, consumer, and commercial banking; and related financial services. We have offices throughout the United States and three European cities. Our major geographic area of concentration is the Midwest and Mid-Atlantic regions, with a growing presence in the Northeast, Southeast and Western United States. Our company’s principal customers are individual investors, corporations, municipalities, and institutions.
	Our Canadian subsidiary, Stifel Nicolaus Canada, Inc. (“SN Canada”) ceased business operations as of September 30, 2013. The results of SN Canada, previously reported in the Institutional Group segment, are classified as discontinued operations for all periods presented. See Note 4 to our consolidated financial statements for further discussion of our discontinued operations.
	Basis of Presentation
	The consolidated financial statements include Stifel Financial Corp. and its wholly owned subsidiaries, principally Stifel Nicolaus and Stifel Bank. All material intercompany balances and transactions have been eliminated. Unless otherwise indicated, the terms “we,” “us,” “our,” or “our company” in this report refer to Stifel Financial Corp. and its wholly owned subsidiaries.
	The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles, which require management to make certain estimates and assumptions that affect the reported amounts. We consider significant estimates, which are most susceptible to change and impacted significantly by judgments, assumptions, and estimates, to be: valuation of financial instruments and investments in partnerships; accrual for contingencies; allowance for loan losses; derivative instruments and hedging activities; fair value of goodwill and intangible assets; provision for income taxes and related tax reserves; and forfeitures associated with stock-based compensation. Actual results could differ from those estimates.
	On March 7, 2011, our Board approved a 50% stock dividend, in the form of a three-for-two stock split, of our common stock payable on April 5, 2011, to shareholders of record as of March 22, 2011. All share and per share information has been retroactively adjusted to reflect the stock split.
	Certain amounts from prior periods have been reclassified to conform to the current period’s presentation. The effect of these reclassifications on our company’s previously reported consolidated financial statements was not material.
	Consolidation Policies
	The consolidated financial statements include the accounts of Stifel Financial Corp. and its subsidiaries. We also have investments or interests in other entities for which we must evaluate whether to consolidate by determining whether we have a controlling financial interest or are considered to be the primary beneficiary. In determining whether to consolidate these entities, we evaluate whether the entity is a voting interest entity or a variable interest entity (“VIE”).
	Voting Interest Entity. Voting interest entities are entities that have (i) total equity investment at risk sufficient to fund expected future operations independently, and (ii) equity holders who have the obligation to absorb losses or receive residual returns and the right to make decisions about the entity’s activities. We consolidate voting interest entities when we determine that there is a controlling financial interest, usually ownership of all, or a majority of, the voting interest.
	Variable Interest Entity. VIEs are entities that lack one or more of the characteristics of a voting interest entity. We are required to consolidate certain VIEs in which we have the power to direct the activities of the entity and the obligation to absorb significant losses or receive significant benefits. In other cases, we consolidate VIEs when we are deemed to be the primary beneficiary. The primary beneficiary is defined as the entity that has a variable interest, or a combination of variable interests, that maintains control and receives benefits or will absorb losses that are not pro rata with its ownership interests. See Note 28 for additional information on VIEs.

Recently Adopted Accounting Guidance [Abstract]	'
Recently Adopted Accounting Guidance	'
	NOTE 2 – Summary of Significant Accounting Policies
	Cash and Cash Equivalents
	We consider money market mutual funds and highly liquid investments with original maturities of three months or less that are not restricted or segregated to be cash equivalents. Cash and cash equivalents include money market mutual funds, deposits with banks, certificates of deposit, and federal funds sold. Cash and cash equivalents also include balances that Stifel Bank maintains at the Federal Reserve Bank.
	Restricted Cash
	Restricted cash consists of cash used as collateral for letters of credit related to certain lease commitments.
	Cash Segregated for Regulatory Purposes
	Our broker-dealer subsidiaries are subject to Rule 15c3-3 under the Securities Exchange Act of 1934, which requires our company to maintain cash or qualified securities in a segregated reserve account for the exclusive benefit of its clients. In accordance with Rule 15c3-3, our company has portions of its cash segregated for the exclusive benefit of clients at December 31, 2013.
	Brokerage Client Receivables, Net
	Brokerage client receivables include receivables of our company’s broker-dealer subsidiaries, which represent amounts due on cash and margin transactions and are generally collateralized by securities owned by clients. Brokerage client receivables, primarily consisting of floating-rate loans collateralized by customer-owned securities, are charged interest at rates similar to other such loans made throughout the industry.  The receivables are reported at their outstanding principal balance net of allowance for doubtful accounts. When a brokerage client receivable is considered to be impaired, the amount of the impairment is generally measured based on the fair value of the securities acting as collateral, which is measured based on current prices from independent sources, such as listed market prices or broker-dealer price quotations. Securities owned by customers, including those that collateralize margin or other similar transactions, are not reflected in the consolidated statements of financial condition.
	Securities Borrowed and Securities Loaned
	Securities borrowed require our company to deliver cash to the lender in exchange for securities and are included in receivables from brokers, dealers, and clearing organizations in the consolidated statements of financial condition. For securities loaned, we receive collateral in the form of cash in an amount equal to the market value of securities loaned. Securities loaned are included in payables to brokers, dealers, and clearing organizations in the consolidated statements of financial condition. We monitor the market value of securities borrowed and loaned on a daily basis, with additional collateral obtained or refunded as necessary. Fees received or paid are recorded in interest revenue or interest expense.
	Substantially all of these transactions are executed under master netting agreements, which gives us right of offset in the event of counterparty default; however, such receivables and payables with the same counterparty are not set-off in the consolidated statements of financial condition.
	Securities Purchased Under Agreements to Resell
	Securities purchased under agreements to resell (“resale agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We obtain control of collateral with a market value equal to or in excess of the principal amount loaned and accrued interest under resale agreements. As of December 31, 2013, we have entered into these agreements with one major financial institution. These agreements are short-term in nature and are collateralized by U.S. government agency securities. We value collateral on a daily basis, with additional collateral obtained when necessary to minimize the risk associated with this activity.
	Financial Instruments
	We measure certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents, financial instruments owned, available-for-sale securities, investments, financial instruments sold, but not yet purchased, and derivatives. Other than those separately discussed in the notes to the consolidated financial statements, the remaining financial instruments are generally short-term in nature, and their carrying values approximate fair value.
	The fair value of a financial instrument is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., “the exit price”) in an orderly transaction between market participants at the measurement date. We have categorized our financial instruments measured at fair value into a three-level classification in accordance with Topic 820, “Fair Value Measurement,” which established a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs reflect our assumptions that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the transparency of inputs as follows:
	Level 1 – Quoted prices (unadjusted) are available in active markets for identical assets or liabilities as of the measurement date. A quoted price for an identical asset or liability in an active market provides the most reliable fair value measurement, because it is directly observable to the market.
	Level 2 – Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the measurement date. The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, derivative instruments whose fair value have been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed.
	Level 3 – Instruments that have little to no pricing observability as of the measurement date. These financial instruments do not have two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation.
	Valuation of Financial Instruments
	When available, we use observable market prices, observable market parameters, or broker or dealer prices (bid and ask prices) to derive the fair value of financial instruments. In the case of financial instruments transacted on recognized exchanges, the observable market prices represent quotations for completed transactions from the exchange on which the financial instrument is principally traded.
	A substantial percentage of the fair value of our financial instruments owned, available-for-sale securities, investments, and financial instruments sold, but not yet purchased, are based on observable market prices, observable market parameters, or derived from broker or dealer prices. The availability of observable market prices and pricing parameters can vary from product to product. Where available, observable market prices and pricing or market parameters in a product may be used to derive a price without requiring significant judgment. In certain markets, observable market prices or market parameters are not available for all products, and fair value is determined using techniques appropriate for each particular product. These techniques involve some degree of judgment.
	For investments in illiquid or privately held securities that do not have readily determinable fair values, the determination of fair value requires us to estimate the value of the securities using the best information available. Among the factors we consider in determining the fair value of investments are the cost of the investment, terms and liquidity, developments since the acquisition of the investment, the sales price of recently issued securities, the financial condition and operating results of the issuer, earnings trends and consistency of operating cash flows, the long-term business potential of the issuer, the quoted market price of securities with similar quality and yield that are publicly traded, and other factors generally pertinent to the valuation of investments. In instances where a security is subject to transfer restrictions, the value of the security is based primarily on the quoted price of a similar security without restriction but may be reduced by an amount estimated to reflect such restrictions. The fair value of these investments is subject to a high degree of volatility and may be susceptible to significant fluctuation in the near term, and the differences could be material.
	The degree of judgment used in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Pricing observability is impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, and the characteristics specific to the transaction. Financial instruments with readily available active quoted prices for which fair value can be measured from actively quoted prices generally will have a higher degree of pricing observability and a lesser degree of judgment used in measuring fair value. Conversely, financial instruments rarely traded or not quoted will generally have less, or no, pricing observability and a higher degree of judgment used in measuring fair value. See Note 6 for additional information on how we value our financial instruments.
	Available-for-Sale and Held-to-Maturity Securities
	Securities available for sale include U.S. government agency securities; state and municipal securities; agency, non-agency, and commercial mortgage-backed securities; corporate fixed income securities; and asset-backed securities.
	Securities held to maturity are recorded at amortized cost based on our company’s positive intent and ability to hold these securities to maturity. Securities held to maturity include agency and commercial mortgage-backed securities, asset-backed securities, consisting of collateralized loan obligation securities and ARS, and corporate fixed income securities.
	We evaluate all securities in an unrealized loss position quarterly to assess whether the impairment is other-than-temporary on a quarterly basis. Our other-than-temporary impairment (“OTTI”) assessment is a subjective process requiring the use of judgments and assumptions. Accordingly, we consider a number of qualitative and quantitative criteria in our assessment, including the extent and duration of the impairment; recent events specific to the issuer and/or industry to which the issuer belongs; the payment structure of the security; external credit ratings and the failure of the issuer to make scheduled interest or principal payments; the value of underlying collateral; current market conditions; and our company’s ability and intent to hold the investment until its value recovers or the securities mature. We may determine that the decline in fair value of an investment is other-than-temporary if our analysis of these factors indicates that we will not recover our investment in the securities.
	If we determine that impairment on our debt securities is other-than-temporary and we have made the decision to sell the security or it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis, we recognize the entire portion of the impairment in earnings. If we have not made a decision to sell the security and we do not expect that we will be required to sell the security prior to recovery of the amortized cost basis, we recognize only the credit component of OTTI in other income in the consolidated statements of operations. The remaining unrealized loss due to factors other than credit, or the non-credit component, is recorded in accumulated other comprehensive loss. We determine the credit component based on the difference between the security’s amortized cost basis and the present value of its expected future cash flows, discounted based on the purchase yield. The non-credit component represents the difference between the security’s fair value and the present value of expected future cash flows.
	We estimate the portion of loss attributable to credit using a discounted cash flow model. Key assumptions used in estimating the expected cash flows include default rates, loss severity, and prepayment rates. Assumptions used can vary widely based on the collateral underlying the securities and are influenced by factors such as collateral type, loan interest rate, geographical location of the borrower, and borrower characteristics.
	Unrealized gains and losses on our available-for-sale securities are reported, net of taxes, in accumulated other comprehensive income included in shareholders’ equity. Amortization of premiums and accretion of discounts are recorded as interest income using the interest method. Realized gains and losses from sales of securities available for sale are determined on a specific identification basis and are included in other revenue in the consolidated statements of operations in the period they are sold.
	Loan Classification
	We classify loans based on our investment strategy and management’s assessment of our intent and ability to hold loans for the foreseeable future or until maturity. Management’s intent and ability with respect to certain loans may change from time to time depending on a number of factors, including economic, liquidity, and capital conditions. The accounting and measurement framework for loans differs depending on the loan classification. The classification criteria and accounting and measurement framework for bank loans and loans held for sale are described below.
	Bank Loans and Allowance for Loan Losses
	Bank loans consist of commercial and residential mortgage loans, home equity loans, stock-secured loans, construction loans, and commercial and industrial and consumer loans originated by Stifel Bank. Bank loans include those loans that management has the intent and ability to hold and are recorded at outstanding principal adjusted for any charge-offs, allowance for loan losses, and deferred origination fees and costs. Loan origination costs, net of fees, are deferred and recognized over the contractual life of the loan as an adjustment of yield using the interest method. Bank loans are generally collateralized by real estate, real property, marketable securities, or other assets of the borrower. Interest income is recognized using the effective interest rate method, which is based upon the respective interest rates and the average daily asset balance.
	We regularly review the loan portfolio and have established an allowance for loan losses for inherent losses estimated to have occurred in the loan portfolio through a provision for loan losses charged to other operating expenses in the consolidated statements of operations. In providing for the allowance for loan losses, we consider historical loss experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available.
	Loans Held for Sale
	Loans that we intend to sell or for which we do not have the ability and intent to hold for the foreseeable future are classified as held for sale. Loans held for sale consist of fixed-rate and adjustable-rate residential real estate mortgage loans intended for sale. Loans held for sale are stated at lower of cost or market value. Declines in market value below cost and any gains or losses on the sale of these assets are recognized in other revenues in the consolidated statements of operations. Market value is determined based on prevailing market prices for loans with similar characteristics or on sale contract prices. Deferred fees and costs related to these loans are not amortized but are recognized as part of the cost basis of the loan at the time it is sold. Because loans held for sale are reported at lower of cost or market value, an allowance for loan losses is not established for loans held for sale.
	Impaired Loans
	A loan is considered impaired when, based on current information and events, it is probable that the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement will not be collectible. Factors considered in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. We determine the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed.
	Once a loan is determined to be impaired, when principal or interest becomes 90 days past due or when collection becomes uncertain, the accrual of interest and amortization of deferred loan origination fees is discontinued (“non-accrual status”) and any accrued and unpaid interest income is reversed. Loans placed on non-accrual status are returned to accrual status when all delinquent principal and interest payments are collected and the collectibility of future principal and interest payments is reasonably assured. Loan losses are charged against the allowance when we believe the uncollectibility of a loan balance is certain. Subsequent recoveries, if any, are credited to the allowance for loan losses.
	Large groups of smaller balance homogenous loans are collectively evaluated for impairment. Accordingly, we do not separately identify individual consumer and residential loans for impairment measurements. Impairment is measured on a loan-by-loan basis for non-homogeneous loans, and a specific allowance is established for individual loans determined to be impaired. Impairment is measured by comparing the carrying value of the impaired loan to the present value of its expected cash flow discounted at the loan's effective interest rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent.
	Other Real Estate Owned
	Assets acquired through, or in lieu of, loan foreclosure by Stifel Bank are held for sale and initially recorded at fair value, less estimated cost to sell, at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed and the assets are carried at the lower of carrying amount or fair value less cost to sell. These valuations are performed by a third-party appraisal firm. Other real estated owned is included in other assets in the consolidated statements of financial condition. Revenue and expense from operations and changes in the valuation allowance are included in other income or other operating expense in the consolidated statements of operations.
	Investments
	Our broker-dealer subsidiaries report changes in fair value of marketable and non-marketable securities in other income in the consolidated statements of operations. The fair value of marketable investments is generally based on either quoted market or dealer prices. The fair value of non-marketable securities is based on management’s estimate using the best information available, which generally consists of quoted market prices for similar securities and internally developed discounted cash flow models.
	Investments in the consolidated statements of financial condition contain investments in securities that are marketable and securities that are not readily marketable. These investments are not included in our broker-dealer trading inventory or available-for-sale or held-to-maturity portfolios and represent the acquiring and disposing of debt or equity instruments for our benefit.
	Fixed Assets
	Office equipment is depreciated on an accelerated basis over the estimated useful life of the asset of two to seven years. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the term of the lease. Buildings and building improvements are amortized on a straight-line basis over the estimated useful life of the asset of three to thirty-nine years. Depreciation expense is recorded in occupancy and equipment rental expense in the consolidated statements of operations. Office equipment, leasehold improvements, and property are stated at cost net of accumulated depreciation and amortization in the consolidated statements of financial condition. Office equipment is reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.
	Goodwill and Intangible Assets
	Goodwill represents the cost of acquired businesses in excess of the fair value of the related net assets acquired. We test goodwill for impairment on an annual basis and on an interim basis when certain events or circumstances exist. We test for impairment at the reporting unit level, which is generally at the level of or one level below our company’s business segments. For both the annual and interim tests, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If after assessing the totality of events or circumstances, we determine it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then performing the two-step impairment test is not required. However, if we conclude otherwise, we are then required to perform the first step of the two-step impairment test. Goodwill impairment is determined by comparing the estimated fair value of a reporting unit with its respective carrying value. If the estimated fair value exceeds the carrying value, goodwill at the reporting unit level is not deemed to be impaired. If the estimated fair value is below carrying value, however, further analysis is required to determine the amount of the impairment. Additionally, if the carrying value of a reporting unit is zero or a negative value and it is determined that it is more likely than not the goodwill is impaired, further analysis is required. The estimated fair values of the reporting units are derived based on valuation techniques we believe market participants would use for each of the reporting units. We have elected July 31 as our annual impairment testing date.
	Identifiable intangible assets, which are amortized over their estimated useful lives, are tested for potential impairment whenever events or changes in circumstances suggest that the carrying value of an asset or asset group may not be fully recoverable.
	Loans and Advances
	We offer transition pay, principally in the form of upfront loans, to financial advisors and certain key revenue producers as part of our company’s overall growth strategy. These loans are generally forgiven by a charge to compensation and benefits over a five- to ten-year period if the individual satisfies certain conditions, usually based on continued employment and certain performance standards. We monitor and compare individual financial advisor production to each loan issued to ensure future recoverability. If the individual leaves before the term of the loan expires or fails to meet certain performance standards, the individual is required to repay the balance. In determining the allowance for doubtful receivables from former employees, management considers the facts and circumstances surrounding each receivable, including the amount of the unforgiven balance, the reasons for the terminated employment relationship, and the former employees’ overall financial situation.
	Securities Sold Under Agreements to Repurchase
	Securities sold under agreements to repurchase (“repurchase agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We make delivery of securities sold under agreements to repurchase and monitor the value of collateral on a daily basis. When necessary, we will deliver additional collateral.
	Derivative Instruments and Hedging Activities
	We recognize all of our derivative instruments at fair value as either assets or liabilities in the consolidated statements of financial condition. These instruments are recorded in other assets or accounts payable and accrued expenses in the consolidated statements of financial condition and in the operating section of the consolidated statements of cash flows as increases or decreases of other assets and accounts payable and accrued expenses. Our company’s policy is not to offset fair value amounts recognized for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral arising from derivative instruments recognized at fair value executed with the same counterparty under master netting arrangements. The accounting for changes in the fair value (i.e., gains and losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments under Topic 815, “Derivatives and Hedging,” we must also designate the hedging instrument or transaction, based upon the exposure being hedged.
	For derivative instruments that are designated and qualify as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income, net of tax, and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any, is recognized in current earnings during the period of change. We do not use derivatives for trading or speculative purposes and, at December 31, 2013, do not have any derivatives that are not designated in qualifying cash flow hedging relationships. See Note 15 for additional details.
	Revenue Recognition
	Customer securities transactions are recorded on a settlement date basis, with related commission revenues and expenses recorded on a trade date basis. Commission revenues are recorded as the amount charged to the customer, which, in certain cases, may include varying discounts. Principal securities transactions are recorded on a trade date basis. We distribute our proprietary equity research products to our client base of institutional investors at no charge. These proprietary equity research products are accounted for as a cost of doing business.
	Investment banking revenues, which include underwriting fees, management fees, advisory fees, and sales credits earned in connection with the distribution of the underwritten securities, are recorded when services for the transactions are completed under the terms of each engagement. Expenses associated with such transactions are deferred until the related revenue is recognized or the engagement is otherwise concluded. Investment banking revenues are presented net of related unreimbursed expenses. Expenses related to investment banking deals not completed are recognized as non-interest expenses in the consolidated statements of operations. For the periods presented, there were no significant expenses recognized for incomplete transactions. We have not recognized any incentive income that is subject to contingent repayments.
Asset management and service fees are recorded when earned, based on the period-end assets in the accounts, and consist of customer account service fees, per account fees (such as IRA fees), and wrap fees on managed accounts.
We earn fees from the investment partnerships that we manage or of which we are a general partner. Such management fees are generally based on the net assets or committed capital of the underlying partnerships. We have agreed, in certain cases, to waive management fees, in lieu of making a cash contribution, in satisfaction of our general partner investment commitments to the investment partnerships. In these cases, we generally recognize our management fee revenues at the time when we are allocated a special profit interest in realized gains from these partnerships.
Direct Financing and Operating Leases
The net investment in direct financing leases resulting from our acquisition of East Shore Aircraft LLC (“East Shore”) is included in other assets in the consolidated balance sheets and consists of the present values of the sum of the future minimum lease payments and estimated residual value of the leased assets. Revenue consists of interest earned on the net investment and is recognized over the lease term as a constant percentage return thereon. The net investment in property on operating leases is included in fixed assets in the consolidated balance sheets. Depreciation is recognized, on the straight-line basis, over the lease term to the estimated residual value. Operating lease revenue is recorded on a straight-line basis and is recognized over the lease term in other income. Estimated residual values are established at lease inception utilizing contract terms, past customer experience, and general market data and are reviewed and adjusted, if necessary, on an annual basis. See Note 3 – Acquisitions further details.
We had a net investment in direct financing leases of $53.7 million at December 31, 2012, which is included in other assets in the consolidated statements of financial condition. This net investment included unearned income of $43.7 million at December 31, 2012.  We did not have an investment in direct financing leases at December 31, 2013.
We lease office space and equipment under operating leases. We recognize rent expense related to these operating leases on a straight-line basis over the lease term. The lease term commences on the earlier of the date when we become legally obligated for the rent payments or the date on which we take possession of the property. For tenant improvement allowances and rent holidays, we record a deferred rent liability in accounts payable and accrued expenses in the consolidated statements of financial condition and amortize the deferred rent over the lease term as a reduction to occupancy and equipment rental expense in the consolidated statements of operations.
Income Taxes
We compute income taxes using the asset and liability method, under which deferred income taxes are provided for the temporary differences between the financial statement carrying amounts and the tax basis of our company’s assets and liabilities. We establish a valuation allowance for deferred tax assets if it is more likely than not that these items will either expire before we are able to realize their benefits, or that future deductibility is uncertain.
We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. We recognize interest and penalties related to uncertain tax positions in provision for income taxes/(benefit) in the consolidated statements of operations. See Note 25 for further information regarding income taxes.
Foreign Currency Translation
We consolidate our foreign subsidiaries, which have designated their local currency as their functional currency. Assets and liabilities of these foreign subsidiaries are translated at year-end rates of exchange, and revenues and expenses are translated at an average rate for the period. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 830, “Foreign Currency Matters,” gains or losses resulting from translating foreign currency financial statements are reflected in accumulated other comprehensive income, a separate component of shareholders’ equity. Gains or losses resulting from foreign currency transactions are included in net income.
Recently Adopted Accounting Guidance
Indefinite-Lived Assets Impairment Testing
In July 2012, the FASB issued Update No. 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment,” which permits entities to make a qualitative assessment of whether it is more likely than not that an indefinite-lived asset is impaired. If an entity concludes that it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount, it would not be required to perform a quantitative assessment. The update also allows an entity the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment test. This guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012 (January 1, 2013 for our company) with early adoption permitted. The adoption of this new guidance did not have a material impact on our consolidated financial statements.
Disclosures about Offsetting Assets and Liabilities
In December 2011, the FASB issued Update No. 2011-11, “Disclosures about Offsetting Assets and Liabilities” (“Update No. 2011-11”), which enhance disclosures by requiring improved information about financial and derivative instruments that are either 1) offset (netting assets and liabilities) in accordance with Topic 210 “Balance Sheet,” and Topic 815, “Derivatives and Hedging or 2) subject to an enforceable master netting arrangement or similar agreement. This guidance is effective for interim and annual reporting periods beginning on or after January 1, 2013, and requires retrospective disclosures for comparative periods presented.
In January 2013, the FASB issued Update No. 2013-01, “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities,” which clarifies the scope of Update No. 2011-11 to include derivatives accounted for in accordance with Topic 815, “Derivatives and Hedging”, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset or subject to an enforceable master netting arrangement or similar agreement. This guidance is effective for interim and annual reporting periods beginning on or after January 1, 2013, and requires retrospective disclosures for comparative periods presented. Other than requiring additional disclosures regarding offsetting assets and liabilities, the adoption of this new guidance did not have an impact on our consolidated financial statements. See Note 17 – Disclosures About Offsetting Assets and Liabilities.
Comprehensive Income
In February 2013, the FASB issued Update No. 2013-02, “Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income,” which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. This guidance is effective for interim and annual reporting periods beginning after December 15, 2012 (January 1, 2013 for our company). Other than requiring additional disclosures regarding other comprehensive income, the adoption of this new guidance did not have an impact on our consolidated financial statements.

Acquisition of KBW, Inc.	'
Acquisitions	'
	NOTE 3 Acquisitions
	Acacia Federal Savings Bank (“Acacia Federal”)
	On October 31, 2013, Stifel Bank completed its acquisition of Acacia Federal Savings Bank, a one-branch community bank with approximately $514.4 million in total assets. Established in 1985, Acacia Federal is a federally chartered savings institution with one retail branch located in Falls Church, Virginia. Over 80% of Acacia Federal’s loan portfolio is originated single-family residential mortgages.
	Under the agreement, we acquired approximately $337.1 million of loans, and $180.4 million of other assets (primarily cash and due from banks and investment securities). In addition, we assumed approximately $435.4 million of deposits and $10.0 million of other liabilities. Assets acquired and liabilities assumed were recorded at fair value in accordance with ASC 805, “Business Combinations”. The fair values for loans were estimated using discounted cash flow analyses using interest rates currently being offered for loans with similar terms. This value was reduced by an estimate of probable losses and the credit risk associated with the loans. The fair values of deposits were estimated by discounting cash flows using interest rates currently being offered on deposits with similar maturities.
	We recognized a $7.6 million bargain purchase gain during the year ended December 31, 2013, which is included in other income in the consolidated statements of operations.
	Pro forma information is not presented, because the acquisition is not considered to be material, as defined by the Securities and Exchange Commission (the “SEC”). The results of operations of Acacia Federal have been included in our results prospectively from the date of acquisition.
	Ziegler Lotsoff Capital Management, LLC (“ZLCM”)
	On November 30, 2013, we acquired ZLCM, an asset management firm that provides investment solutions for institutions, mutual fund sub-advisory clients, municipalities, pension plans, Taft-Hartley plans, and individual investors.
	The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 ("Topic 805"), "Business Combinations." Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $6.8 million of goodwill as an asset in the consolidated statement of financial condition, which has been allocated to our company's Global Wealth Management segment. The allocation of the purchase price is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of ZLCM on November 30, 2013 and the identified intangible assets. The final goodwill and intangible assets recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments. In management's opinion, the goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of ZLCM's business and the reputation and expertise of ZLCM in the asset management sector.
	Pro forma information is not presented, because the acquisition is not considered to be material, as defined by the SEC. The results of operations of ZLCM have been included in our results prospectively from the date of acquisition.
	KBW, Inc.
	On February 15, 2013, we completed the purchase of all of the outstanding shares of common stock of KBW, Inc. ("KBW, Inc."), a full-service investment bank specializing in the financial services industry based in New York, New York. The purchase was completed pursuant to the merger agreement dated November 5, 2012. Under the terms of the merger agreement, each share of common stock, including certain restricted stock, of KBW, Inc. issued and outstanding immediately prior to the effective time of the merger was cancelled and converted into the right to receive a combination of (i) cash consideration of $8.00 ($10.00 less the extraordinary dividend amount of $2.00) and (ii) stock consideration of 0.2143 a share of our common stock.
	In conjunction with the close of the merger, we issued 6.7 million shares of common stock to holders of KBW, Inc. common stock, issued 2.2 million restricted stock awards to KBW, Inc. employees, and paid $253.0 million in cash.
	The following summarizes the aggregate merger consideration payable for all outstanding shares and restricted stock awards of KBW, Inc. (in thousands):
	Cash paid to KBW, Inc. shareholders	$	253,039
	Common stock issued to KBW, Inc. shareholders		262,653
	Fair value of outstanding KBW, Inc. restricted stock awards exchanged for Stifel restricted stock awards		86,221
	Purchase price to be allocated	$	601,913
	The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 ("Topic 805"), "Business Combinations." Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $288.3 million of goodwill as an asset in the consolidated statement of financial condition, which has been allocated to our company's Institutional Group segment. In management's opinion, the goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of KBW, Inc.'s business and the reputation and expertise of KBW, Inc. in the financial services sector. Identifiable intangible assets purchased by our company consisted of customer relationships, trade name and investment banking backlog with acquisition-date fair values of $11.0 million, $9.0 million, and $4.0 million, respectively.
	Under Topic 805, merger-related transaction costs (such as advisory, legal, valuation and other professional fees) are not included as components of consideration transferred but are accounted for as expenses in the periods in which the costs are incurred. Transaction costs of $9.8 million were incurred during the year ended December 31, 2013 and are included in other operating expenses in the consolidated statement of operations.
	In addition, on February 15, 2013, certain employees were granted restricted stock or restricted stock units of our company as retention. The fair value of the awards issued as retention was $30.6 million. There are no continuing service requirements associated with these restricted stock units, and accordingly were expensed at date of grant. This charge is included in compensation and benefits in the consolidated statement of operations for the year ended December 31, 2013.
	The following table summarizes the preliminary fair value of assets acquired and liabilities assumed at the date of the acquisition (in thousands):
	Assets:
	Cash and cash equivalents	$	98,756

	Miller Buckfire & Co. LLC
	On December 20, 2012, we acquired 100% of the ordinary members’ partnership interests in Miller Buckfire & Co. LLC (“Miller Buckfire”), an investment banking firm. Miller Buckfire provides a full range of investment banking advisory services, including financial restructuring, mergers and acquisitions, and debt and equity placements.
	The aggregate consideration paid by us in the Miller Buckfire acquisition included $7.3 million in cash, our initial investment of $28.0 million and common stock with a fair value of $21.7 million. The fair value of the common stock was determined using the market price of our common stock on the acquisition date. The acquisition of Miller Buckfire enables us to efficiently provide capital markets and investment banking services to clients with special financing needs, such as those historically provided by Miller Buckfire. Identifiable intangible assets purchased by our company consisted of trade name with acquisition-date fair value of $2.1 million.
	The acquisition was accounted for under the acquisition method of accounting in accordance with Topic 805 “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the fair value of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $60.3 million of goodwill as an asset in the consolidated statement of financial condition, which has been allocated to our company’s Institutional Group reporting segment. In management’s opinion, the goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of Miller Buckfire’s business and the reputation and expertise of Miller Buckfire in the investment banking business. Goodwill will be deductible for federal income tax purposes.
	East Shore Aircraft LLC
	On December 21, 2012, we completed the acquisition of East Shore. East Shore was initially formed to acquire fifteen Boeing 757-200 aircraft from UAL in sale-leaseback transactions with UAL. The purchase price of $112.9 million was financed through a combination of existing cash and the issuance of non-recourse debt. During the year ended December 31, 2013, we sold all of the aircraft purchased in 2012 and used the proceeds to pay-off the remaining principal balance of the non-recourse debt.
	Stone & Youngberg LLC
	On October 1, 2011, we acquired Stone & Youngberg, a leading financial services firm specializing in municipal finance and fixed income securities. The purchase consideration consisted of cash, a portion paid at closing and $24.0 million to be paid in installments over the next three years, and common stock. In addition, we may be required to pay a contingent earn-out over a five-year period after the closing, which is capped at $25.0 million, based upon revenue goals, as established in the purchase agreement.
	We recognized a liability for estimated earn-out payments over the five-year period. Additionally, we recognized a liability for the installment payments to be made over the next two years. As of December 31, 2013, we have a liability for the estimated earn-out payments and installment payments of $35.6 million, which is included in accounts payable and accrued expenses in the consolidated statements of financial condition. We have the right of offset for legal matters as defined in the purchase agreement.

Fair Value Measurements	12 Months Ended

Fair Value Measurements [Abstract]	'
Fair Value Measurements	'
	NOTE 6 – Fair Value Measurements
	We measure certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents, trading securities owned, available-for-sale securities, investments, trading securities sold, but not yet purchased, securities sold, but not yet purchased, and derivatives.
	We generally utilize third-party pricing services to value Level 1 and Level 2 available-for-sale investment securities, as well as certain derivatives designated as cash flow hedges. We review the methodologies and assumptions used by the third-party pricing services and evaluate the values provided, principally by comparison with other available market quotes for similar instruments and/or analysis based on internal models using available third-party market data. We may occasionally adjust certain values provided by the third-party pricing service when we believe, as the result of our review, that the adjusted price most appropriately reflects the fair value of the particular security.
	The following is a description of the valuation techniques and key inputs used to measure fair value on a recurring basis:
	Cash Equivalents
	Cash equivalents include highly liquid investments with original maturities of three months or less. Due to their short-term nature, the carrying amount of these instruments approximates the estimated fair value. Actively traded money market funds are measured at their net asset value, which approximates fair value. As such, we classify the estimated fair value of these instruments as Level 1.
	Financial Instruments Owned and Available-For-Sale Securities
	When available, the fair value of financial instruments are based on quoted prices in active markets and reported in Level 1. Level 1 financial instruments include highly liquid instruments with quoted prices, such as equity securities listed in active markets, corporate fixed income securities, and U.S. government securities.
	If quoted prices are not available, fair values are obtained from pricing services, broker quotes, or other model-based valuation techniques with observable inputs, such as the present value of estimated cash flows, and reported as Level 2. The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value have been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed. Level 2 financial instruments include U.S. government agency securities, mortgage-backed securities, corporate fixed income securities infrequently traded, state and municipal securities, asset-backed securities, and equity securities not actively traded.
	We have identified Level 3 financial instruments to include certain corporate fixed income securities with unobservable pricing inputs, and certain state and municipal securities, which include auction rate securities (“ARS”). Level 3 financial instruments have little to no pricing observability as of the report date. These financial instruments do not have active two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation. ARS are valued based upon our expectations of issuer redemptions and using internal discounted cash flow models that utilize unobservable inputs.
	Investments
	Investments in certain equity securities and mutual funds are valued based on quoted prices (unadjusted) in active markets and reported in Level 1. Investments in certain private equity securities and partnerships with unobservable inputs and ARS for which the market has been dislocated and largely ceased to function are reported as Level 3 assets. Investments in certain equity securities with unobservable inputs are valued using management’s best estimate of fair value, where the inputs require significant management judgment. ARS are valued based upon our expectations of issuer redemptions and are evaluated using internal models.
	Investments in partnerships and other investments include our general and limited partnership interests in investment partnerships and direct investments in non-public companies. The net assets of investment partnerships consist primarily of investments in non-marketable securities. The value of these investments is at risk to changes in equity markets, general economic conditions, and a variety of other factors. We estimate fair value for private equity investments based on our percentage ownership in the net asset value of the entire fund, as reported by the fund or on behalf of the fund, after indication that the fund adheres to applicable fair value measurement guidance.
	The valuation of these investments requires significant management judgment due to the absence of quoted market prices, inherent lack of liquidity, and long-term nature of these assets. As a result, these values cannot be determined with precision and the calculated fair value estimates may not be realizable in a current sale or immediate settlement of the instrument.
	For those funds where the net asset value is not reported by the fund, we derive the fair value of the fund by estimating the fair value of each underlying investment in the fund. In addition to using qualitative information about each underlying investment, as provided by the fund, we give consideration to information pertinent to the specific nature of the debt or equity investment, such as relevant market conditions, offering prices, operating results, financial conditions, exit strategy, and other qualitative information, as available. The lack of an independent source to validate fair value estimates, including the impact of future capital calls and transfer restrictions, is an inherent limitation in the valuation process.  Commitments to fund additional investments in nonmarketable equity securities recorded at fair value were $12.4 million and $3.0 million at December 31, 2013 and 2012, respectively.
	Financial Instruments Sold, But Not Yet Purchased
	Financial instruments sold, but not purchased, recorded at fair value based on quoted prices in active markets and other observable market data include highly liquid instruments with quoted prices, such as U.S. government securities, corporate fixed income securities, and equity securities listed in active markets, which are reported as Level 1.
	If quoted prices are not available, fair values are obtained from pricing services, broker quotes, or other model-based valuation techniques with observable inputs, such as the present value of estimated cash flows, and reported as Level 2. The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value have been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed. Level 2 financial instruments include U.S. government agency securities, certain equity securities not actively traded, certain corporate fixed income securities, and statement and municipal securities.
	Derivatives
	Derivatives are valued using quoted market prices when available or pricing models based on the net present value of estimated future cash flows. The valuation models used require market observable inputs, including contractual terms, market prices, yield curves, credit curves, and measures of volatility. We manage credit risk for our derivative positions on a counterparty-by-counterparty basis and calculate credit valuation adjustments, included in the fair value of these instruments, on the basis of our relationships at the counterparty portfolio/master netting agreement level. These credit valuation adjustments are determined by applying a credit spread for the counterparty to the total expected exposure of the derivative after considering collateral and other master netting arrangements. We have classified our interest rate swaps as Level 2.

The results included in the table above are only a component of the overall investment strategies of our company. The table above does not present Level 1 or Level 2 valued assets or liabilities. The changes to our company’s Level 3 classified instruments were principally a result of: unrealized gains and losses, and redemptions of ARS at par during the year ended December 31, 2013.
During the year ended December 31, 2013, financial instruments owned and investments acquired as part of the KBW merger that are classified as Level 3 totaled $54.1 million. The changes in unrealized gains/(losses) recorded in earnings for the year ended December 31, 2013, relating to Level 3 assets still held at December 31, 2013, were immaterial.
The following table summarizes quantitative information related to the significant unobservable inputs utilized in our company’s Level 3 recurring fair value measurements as of December 31, 2013.
		Valuation technique	Unobservable input		Range		Weighted average
Available-for-sale securities:
Asset-backed securities		Discounted cash flow	Discount rate		5.7% - 11.1%		7.7%
			Workout period		1 - 4 years		3.4 years
Investments:
Auction rate securities
Equity securities		Discounted cash flow	Discount rate		2.9%  - 12.7%		7.2%
			Workout period		1 - 3 years		2.4 years
Municipal securities		Discounted cash flow	Discount rate		0.1% - 10.8%		6.5%
			Workout period		1 -4  years		2.6 years
Other
Investments in partnerships		Market approach	Revenue multiple		1.7-4.0		2.6
			EBITDA multiple		4.5-9.9		7.7
Private equity investments		Market approach	Revenue multiple		0.5-3.0		1.8
			EBITDA multiple		4.3-11.3		7.8
The fair value of certain Level 3 assets was determined using various methodologies as appropriate, including NAVs of underlying investments, third-party pricing vendors, broker quotes and market and income approaches. These inputs are evaluated for reasonableness through various procedures, including due diligence reviews of third-party pricing vendors, variance analyses, consideration of current market environment, and other analytical procedures.
The fair value for our auction-rate securities was determined using an income approach based on an internally developed discounted cash flow model. The discounted cash flow model utilizes two significant unobservable inputs: discount rate and workout period. The discount rate was calculated using credit spreads of the underlying collateral or similar securities. The workout period was based on an assessment of publicly available information on efforts to re-establish functioning markets for these securities and our company’s own redemption experience. Significant increases in any of these inputs in isolation would result in a significantly lower fair value. On an ongoing basis, management verifies the fair value by reviewing the appropriateness of the discounted cash flow model and its significant inputs.
General and limited partnership interests in investment partnerships totaled $56.0 million and $21.5 million at December 31, 2013 and 2012, respectively. The general and limited partnership interests in investment partnerships were primarily valued based upon NAVs received from third-party fund managers. The various partnerships are investment companies, which record their underlying investments at fair value based on fair value policies established by management of the underlying fund. Fair value policies at the underlying fund generally require the funds to utilize pricing/valuation information, including independent appraisals, from third-party sources. However, in some instances, current valuation information for illiquid securities or securities in markets that are not active may not be available from any third-party source or fund management may conclude that the valuations that are available from third-party sources are not reliable. In these instances, fund management may perform model-based analytical valuations that may be used as an input to value these investments.
Direct investments in private equity companies totaled $8.2 million and $13.5 million at December 31, 2013 and 2012, respectively. Direct investments in private equity companies may be valued using the market approach or the income approach, or a combination thereof, and were valued based on an assessment of each underlying investment, incorporating evaluation of additional significant third-party financing, changes in valuations of comparable peer companies, the business environment of the companies, market indices, assumptions relating to appropriate risk adjustments for nonperformance and legal restrictions on disposition, among other factors. The fair value derived from the methods used are evaluated and weighted, as appropriate, considering the reasonableness of the range of values indicated. Under the market approach, fair value may be determined by reference to multiples of market-comparable companies or transactions, including earnings before interest, taxes, depreciation and amortization (“EBITDA”) multiples. Under the income approach, fair value may be determined by discounting the cash flows to a single present amount using current market expectations about those future amounts. Unobservable inputs used in a discounted cash flow model may include projections of operating performance generally covering a five-year period and a terminal value of the private equity direct investment. For securities utilizing the discounted cash flow valuation technique, a significant increase (decrease) in the discount rate, risk premium or discount for lack of marketability in isolation could result in a significantly lower (higher) fair value measurement. For securities utilizing the market comparable companies valuation technique, a significant increase (decrease) in the EBITDA multiple in isolation could result in a significantly higher (lower) fair value measurement.
Transfers Within the Fair Value Hierarchy
We assess our financial instruments on a quarterly basis to determine the appropriate classification within the fair value hierarchy. Transfers between fair value classifications occur when there are changes in pricing observability levels. Transfers of financial instruments among the levels are deemed to occur at the beginning of the reporting period. There were $81.2 million of transfers of financial assets from Level 2 to Level 1 during the year ended December 31, 2013, primarily related to tax-exempt securities for which market trades were observed that provided transparency into the valuation of these assets. There were $35.8 million of transfers of financial assets from Level 1 to Level 2 during the year ended December 31, 2013, primarily related to tax-exempt securities for which there were low volumes of recent trade activity observed.

The following, as supplemented by the discussion above, describes the valuation techniques used in estimating the fair value of our financial instruments as of December 31, 2013 and 2012.
Financial Assets
Securities Purchased Under Agreements to Resell
Securities purchased under agreements to resell are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. The carrying values at December 31, 2013 and 2012 approximate fair value due to the short-term nature.
Held-to-Maturity Securities
The estimated fair value, included in the above table, is determined using several factors; however, primary weight is given to discounted cash flow modeling techniques that incorporated an estimated discount rate based upon recent observable debt security issuances with similar characteristics.
Bank Loans
The fair values of mortgage loans and commercial loans were estimated using a discounted cash flow method, a form of the income approach. Discount rates were determined considering rates at which similar portfolios of loans would be made under current conditions and considering liquidity spreads applicable to each loan portfolio based on the secondary market.
Financial Liabilities
Securities Sold Under Agreements to Repurchase
Securities sold under agreements to repurchase are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. The carrying values at December 31, 2013 and 2012 approximate fair value due to the short-term nature.
Bank Deposits
The fair value for demand deposits is equal to the amount payable on demand at the reporting date (that is, their carrying amounts). The carrying amounts of variable-rate money market and savings accounts approximate their fair values at the reporting date as these are short-term in nature. The fair value of other interest-bearing deposits, including certificates of deposit, was calculated by discounting the future cash flows using discount rates based on the expected current market rates for similar products with similar remaining terms.
Senior Notes
The fair value of our senior notes is estimated based upon quoted market prices.
Non-Recourse Debt
The fair value of our non-recourse debt is based on the discounted value of contractual cash flows. We have assumed a discount rate based on the coupon achieved in our 6.7% senior notes due 2022.
Debentures to Stifel Financial Capital Trusts
The fair value of our trust preferred securities is based on the discounted value of contractual cash flows. We have assumed a discount rate based on the coupon achieved in our 6.7% senior notes due 2022.
Liabilities Subordinated to Claims of General Creditors
The fair value of subordinated debt was measured using the interest rates commensurate with borrowings of similar terms.
These fair value disclosures represent our best estimates based on relevant market information and information about the financial instruments. Fair value estimates are based on judgments regarding future expected losses, current economic conditions, risk characteristics of the various instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in the above methodologies and assumptions could significantly affect the estimates.

	During the year ended December 31, 2013, we transferred $1.1 billion of mortgage-backed securities from our available-for-sale portfolio to the held-to-maturity category reflecting our company’s intent to hold those securities to maturity. During the year ended December 31, 2013, we transferred $387.5 million from our held-to-maturity portfolio to the available-for-sale category as these CLO investments may become non-compliant under the provisions of the new Volcker Rule, which could require us to sell them before maturity.
	For the years ended December 31, 2013, 2012, and 2011, we received proceeds of $197.5 million,  $250.2 million, and $362.1 million, respectively, from the sale of available-for-sale securities, which resulted in realized gains of $2.0 million,  $3.8 million, and $7.9 million, respectively.
	During the year ended December 31, 2013, unrealized losses, net of deferred taxes, of $48.5 million was recorded in accumulated other comprehensive income/(loss) in the consolidated statements of financial condition. During the years ended December 31, 2012 and 2011, unrealized gains, net of deferred taxes, of $8.7 million and $2.1 million, respectively, were recorded in accumulated other comprehensive income/(loss) in the consolidated statements of financial condition.

The gross unrealized losses on our available-for-sale securities of $20.3 million as of December 31, 2013 relate to 100 individual securities.
Certain investments in the available-for-sale portfolio at December  31, 2013, are reported in the consolidated statements of financial condition at an amount less than their amortized cost. The total fair value of these investments at December  31, 2013, was $800.7 million, which was 45.6% of our available-for-sale investment portfolio. The amortized cost basis of these investments was $821.0 million at December 31, 2013. As discussed in more detail below, we conduct periodic reviews of all securities with unrealized losses to assess whether the impairment is other-than-temporary.
Other-Than-Temporary Impairment
We evaluate all securities in an unrealized loss position quarterly to assess whether the impairment is other-than-temporary. Our other-than-temporary impairment (“OTTI”) assessment is a subjective process requiring the use of judgments and assumptions. There was no credit-related OTTI recognized during the year ended December 31, 2013. Based on the evaluation, we recognized a credit-related OTTI of $0.6 million and $1.9 million in earnings for the years ended December 31, 2012 and 2011, respectively.
We believe the gross unrealized losses related to all other securities of $20.3 million as of December 31, 2013, are attributable to issuer-specific credit spreads and changes in market interest rates and asset spreads. We, therefore, do not expect to incur any credit losses related to these securities. In addition, we have no intent to sell these securities with unrealized losses, and it is not more likely than not that we will be required to sell these securities prior to recovery of the amortized cost. At December 31, 2013, the CLOs in our available-for-sale portfolio had $2.9 million in unrealized losses. No OTTI charge was recorded in 2013 related to these securities. Accordingly, we have concluded that the impairment on these securities is not other-than-temporary.

	A loan is determined to be impaired, when principal or interest becomes 90 days past due or when collection becomes uncertain. At the time a loan is determined to be impaired, the accrual of interest and amortization of deferred loan origination fees is discontinued (“non-accrual status”), and any accrued and unpaid interest income is reversed. At December 31, 2013, we had $1.5 million of non-accrual loans, which included $0.4 million in troubled debt restructurings, for which there was a specific allowance of $0.2 million. At December 31, 2012, we had $1.8 million of non-accrual loans, which included $1.6 million in troubled debt restructurings, for which there was a specific allowance of $0.6 million. The gross interest income related to impaired loans, which would have been recorded had these loans been current in accordance with their original terms, and the interest income recognized on these loans during the years ended December 31, 2013, 2012, and 2011 were insignificant to the consolidated financial statements.
	Credit Quality
	We closely monitor economic conditions and loan performance trends to manage and evaluate our exposure to credit risk. Trends in delinquency ratios are an indicator, among other considerations, of credit risk within our loan portfolios. The level of nonperforming assets represents another indicator of the potential for future credit losses. Accordingly, key metrics we track and use in evaluating the credit quality of our loan portfolio include delinquency and nonperforming asset rates, as well as charge-off rates and our internal risk ratings of the loan portfolio. In general, we are a secured lender. At December 31, 2013 and 2012, 96.8% and 96.1% of our loan portfolio was collateralized, respectively. Collateral is required in accordance with the normal credit evaluation process based upon the creditworthiness of the customer and the credit risk associated with the particular transaction.
	The following is a breakdown of the allowance for loan losses by type for as of December 31, 2013 and 2012 (in thousands, except rates):

	NOTE 12 –  Short-Term Borrowings
	Our short-term financing is generally obtained through short-term bank line financing on an uncommitted, secured basis, committed short-term bank line financing on an unsecured basis and securities lending arrangements. We borrow from various banks on a demand basis with company-owned and customer securities pledged as collateral. The value of customer-owned securities used as collateral is not reflected in the consolidated statements of financial condition. Our uncommitted secured lines of credit at December 31, 2013 totaled $680.0 million with four banks and are dependent on having appropriate collateral, as determined by the bank agreements, to secure an advance under the line. The availability of our uncommitted lines is subject to approval by the individual banks each time an advance is requested and may be denied. Our peak daily borrowing was $561.2 million during the year ended December 31, 2013. There are no compensating balance requirements under these arrangements.
	Our committed short-term bank line financing at December 31, 2013 consisted of a $100.0 million revolving credit facility. The credit facility expires in December 2014. The applicable interest rate under the revolving credit facility is calculated as a per annum rate equal to the one-month Eurocurrency rate plus 1.00%, as defined in the revolving credit facility. At December 31, 2013, we had no advances on our revolving credit facility and were in compliance with all covenants.
	At December 31, 2013, short-term borrowings from banks were $55.7 million at an average rate of 1.22%, which were collateralized by company-owned securities valued at $440.8 million. At December 31, 2012, short-term borrowings from banks were $304.7 million at an average rate of 1.14%, which were collateralized by company-owned securities valued at $530.7 million. The average bank borrowing was $252.9 million,  $184.4 million, and $199.6 million for the years ended December 31, 2013, 2012, and 2011, respectively, at average daily interest rates of 1.26%,  1.10%, and 1.15%, respectively.
	At December 31, 2013 and 2012, Stifel had a stock loan balance of $40.1 million and $19.2 million, respectively, at average daily interest rates of 0.16% and 0.24%, respectively.

Derivative Instruments And Hedging Activities	'
	NOTE 15 –  Derivative Instruments and Hedging Activities
	We use interest rate swaps as part of our interest rate risk management strategy. Interest rate swaps generally involve the exchange of fixed and variable rate interest payments between two parties, based on a common notional principal amount and maturity date with no exchange of underlying principal amounts. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for our company making fixed payments. Our policy is not to offset fair value amounts recognized for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral arising from derivative instruments recognized at fair value executed with the same counterparty under master netting arrangements.
	The following table provides the notional values and fair values of our derivative instruments as of December 31, 2013 and 2012 (in thousands):
		31-Dec-13
				Asset derivatives				Liability derivatives
		Notional value		Balance sheet location		Positive fair value		Balance sheet location		Negative fair value

	Cash flow interest rate contracts	$	550,127		Other assets	$	-		Accounts payable and accrued expenses	$	-19,934
	Cash Flow Hedges
	We have entered into interest rate swap agreements that effectively modify our exposure to interest rate risk by converting floating rate debt to a fixed rate debt over the next ten years.
	Any unrealized gains or losses related to cash flow hedging instruments are reclassified from accumulated other comprehensive loss into earnings in the same period the hedged forecasted transaction affects earnings and are recorded in interest expense on the accompanying consolidated statements of operations. The ineffective portion of the cash flow hedging instruments is recorded in other income or other operating expense. The loss recognized during the year ended December 31, 2013 related to ineffectiveness was insignificant.
	Amounts reported in accumulated other comprehensive loss related to derivatives will be reclassified to interest expense as interest payments are made on our variable rate deposits. During the next twelve months, we estimate that $6.0 million will be reclassified as an increase to interest expense.
	The following table shows the effect of our company’s derivative instruments in the consolidated statements of operations for the years ended December 31, 2013, 2012, and 2011 (in thousands):
		Year ended December 31, 2013

	We maintain a risk management strategy that incorporates the use of derivative instruments to minimize significant unplanned fluctuations in earnings caused by interest rate volatility. Our goal is to manage sensitivity to changes in rates by hedging the maturity characteristics of variable rate affiliated deposits, thereby limiting the impact on earnings. By using derivative instruments, we are exposed to credit and market risk on those derivative positions. We manage the market risk associated with interest rate contracts by establishing and monitoring limits as to the types and degree of risk that may be undertaken. Credit risk is equal to the extent of the fair value gain in a derivative if the counterparty fails to perform. When the fair value of a derivative contract is positive, this generally indicates that the counterparty owes our company and, therefore, creates a repayment risk for our company. When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, have no repayment risk. See Note 6 in the notes to our consolidated financial statements for further discussion on how we determine the fair value of our financial instruments. We minimize the credit (or repayment) risk in derivative instruments by entering into transactions with high-quality counterparties that are reviewed periodically by senior management.
	Credit Risk-Related Contingency Features
	We have agreements with our derivative counterparties containing provisions where if we default on any of our indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then we could also be declared in default on our derivative obligations.
	We have agreements with certain of our derivative counterparties that contain provisions where if our shareholders’ equity declines below a specified threshold or if we fail to maintain a specified minimum shareholders’ equity, then we could be declared in default on our derivative obligations.
	Certain of our agreements with our derivative counterparties contain provisions where if a specified event or condition occurs that materially changes our creditworthiness in an adverse manner, we may be required to fully collateralize our obligations under the derivative instrument.
	Regulatory Capital-Related Contingency Features
	Certain of our derivative instruments contain provisions that require us to maintain our capital adequacy requirements. If we were to lose our status as “adequately capitalized,” we would be in violation of those provisions, and the counterparties of the derivative instruments could request immediate payment or demand immediate and ongoing full overnight collateralization on derivative instruments in net liability positions.
	As of December 31, 2013, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $9.3 million (termination value). We have minimum collateral posting thresholds with certain of our derivative counterparties and have posted cash collateral of $24.0 million against our obligations under these agreements. If we had breached any of these provisions at December 31, 2013, we would have been required to settle our obligations under the agreements at the termination value.
	Counterparty Risk
	In the event of counterparty default, our economic loss may be higher than the uncollateralized exposure of our derivatives if we were not able to replace the defaulted derivatives in a timely fashion. We monitor the risk that our uncollateralized exposure to each of our counterparties for interest rate swaps will increase under certain adverse market conditions by performing periodic market stress tests. These tests evaluate the potential additional uncollateralized exposure we would have to each of these derivative counterparties assuming changes in the level of market rates over a brief time period.

	We also provide guarantees to securities clearinghouses and exchanges under their standard membership agreement, which requires members to guarantee the performance of other members. Under the agreement, if another member becomes unable to satisfy its obligations to the clearinghouse, other members would be required to meet shortfalls. Our liability under these agreements is not quantifiable and may exceed the cash and securities we have posted as collateral. However, the potential requirement for us to make payments under these arrangements is considered remote. Accordingly, no liability has been recognized for these arrangements.
	Thomas Weisel Partners LLC (“TWP”) has entered into settlement and release agreements (“Settlement Agreements”) with certain customers, whereby it will purchase their ARS, at par, in exchange for a release from any future claims. At December 31, 2013, we estimate that TWP customers held $18.3 million par value of ARS, which may be repurchased over the next 2 years. The amount estimated for repurchase assumes no issuer redemptions.
	Other Commitments
	In the ordinary course of business, Stifel Bank has commitments to extend credit in the form of commitments to originate loans, standby letters of credit, and lines of credit. See Note 23 in the notes to our consolidated financial statements for further details.
	We have committed capital to certain entities and these commitments generally have no specified call dates. We had $76.0 million of commitments outstanding at December 31, 2013, of which $63.3 million relate to commitments to certain strategic relationships with Business Development Corporations.
	Concentration of Credit Risk
	We provide investment, capital-raising, and related services to a diverse group of domestic customers, including governments, corporations, and institutional and individual investors. Our exposure to credit risk associated with the non-performance of customers in fulfilling their contractual obligations pursuant to securities transactions can be directly impacted by volatile securities markets, credit markets, and regulatory changes. This exposure is measured on an individual customer basis and on a group basis for customers that share similar attributes. To reduce the potential for risk concentrations, counterparty credit limits have been implemented for certain products and are continually monitored in light of changing customer and market conditions. As of December 31, 2013 and December 31, 2012, we did not have significant concentrations of credit risk with any one customer or counterparty, or any group of customers or counterparties.
	Operating Leases and Purchase Obligations
	Future minimum commitments under non-cancelable operating leases at December 31, 2013, are as follows (in thousands):
	2014	$	65,936
	2015		67,126
	2016		59,908
	2017		51,006
	2018		40,823
	Thereafter		164,259
		$	449,058
	Certain leases contain provisions for renewal options and escalation clauses based on increases in certain costs incurred by the lessor. We amortize office lease incentives and rent escalation on a straight-line basis over the life of the lease. Rent expense for the years ended December 31, 2013, 2012, and 2011 was $79.8 million, $60.0 million, and $58.6 million, net of sublease income.

Legal Proceedings [Abstract]	'
Legal Proceedings	'
	NOTE 20 – Legal Proceedings
	Our company and its subsidiaries are named in and subject to various proceedings and claims arising primarily from our securities business activities, including lawsuits, arbitration claims, class actions, and regulatory matters. Some of these claims seek substantial compensatory, punitive, or indeterminate damages. Our company and its subsidiaries are also involved in other reviews, investigations, and proceedings by governmental and self-regulatory organizations regarding our business, which may result in adverse judgments, settlements, fines, penalties, injunctions, and other relief. We are contesting the allegations in these claims, and we believe that there are meritorious defenses in each of these lawsuits, arbitrations, and regulatory investigations. In view of the number and diversity of claims against the company, the number of jurisdictions in which litigation is pending, and the inherent difficulty of predicting the outcome of litigation and other claims, we cannot state with certainty what the eventual outcome of pending litigation or other claims will be.
	We have established reserves for potential losses that are probable and reasonably estimable that may result from pending and potential legal actions, investigations and regulatory proceedings. In many cases, however, it is inherently difficult to determine whether any loss is probable or even possible or to estimate the amount or range of any potential loss, particularly where proceedings may be in relatively early stages or where plaintiffs are seeking substantial or indeterminate damages. Matters frequently need to be more developed before a loss or range of loss can reasonably be estimated.
	In our opinion, based on currently available information, review with outside legal counsel, and consideration of amounts provided for in our consolidated financial statements with respect to these matters, including the matters described below, the ultimate resolution of these matters will not have a material adverse impact on our financial position and results of operations. However, resolution of one or more of these matters may have a material effect on the results of operations in any future period, depending upon the ultimate resolution of those matters and depending upon the level of income for such period. For matters where a reserve has not been established and for which we believe a loss is reasonably possible, as well as for matters where a reserve has been recorded but for which an exposure to loss in excess of the amount accrued is reasonably possible, based on currently available information, we believe that such losses will not have a material effect on our consolidated financial statements.
	SEC/Wisconsin Lawsuit
	The SEC filed a civil lawsuit against our company in U.S. District Court for the Eastern District of Wisconsin on August 10, 2011. The action arises out of our role in investments made by five Southeastern Wisconsin school districts (the “school districts”) in transactions involving collateralized debt obligations (“CDOs”). These transactions are described in more detail below in connection with the civil lawsuit filed by the school districts. The SEC has asserted claims under Section 15c(1)(A), Section 10b and Rule 10b-5 of the Exchange Act and Sections 17a(1), 17a(2) and 17a(3) of the Securities Act. The claims are based upon both alleged misrepresentations and omissions in connection with the sale of the CDOs to the school districts, as well as the allegedly unsuitable nature of the CDOs. On October 31, 2011, we filed a motion to dismiss the action for failure to state a claim. The District Court granted in part and denied in part our motion to dismiss, and as a result the SEC has amended its complaint. We answered, denied the substantive allegations of the amended complaint and asserted various affirmative defenses.  We believe, based upon currently available information and review with outside counsel, that we have meritorious defenses to the SEC’s lawsuit and intend to vigorously defend the SEC’s claims.
	We were named in a civil lawsuit filed in the Circuit Court of Milwaukee, Wisconsin (the “Wisconsin State Court”) on September 29, 2008. The lawsuit was filed against our company, Stifel, as well as Royal Bank of Canada Europe Ltd. (“RBC”), and certain other RBC entities (collectively the “RBC entities”) by the school districts and the individual trustees for other post-employment benefit (“OPEB”) trusts established by those school districts (collectively the “Plaintiffs”). This lawsuit relates to the same transactions that are the subject of the SEC action noted above.  As we previously disclosed, we entered into a settlement of the Plaintiffs’ lawsuit against our company and Stifel in March, 2012. The settlement provides the potential for the Plaintiffs to obtain significant additional damages from the RBC entities. The school districts are continuing their lawsuit against RBC, and we are pursuing claims against the RBC entities to recover payments we have made to the school districts and for amounts owed to the OPEB trusts. Subsequent to the settlement, RBC asserted claims against the school districts, our company and Stifel for fraud, negligent misrepresentation, strict liability misrepresentation and information negligently provided for the guidance of others based upon our role in connection with the school districts’ purchase of the CDOs.  RBC has also asserted claims against our company and Stifel for civil conspiracy and conspiracy to injure its business based upon the settlement by our company and Stifel with the school districts and pursuit of claims against the RBC entities.  We moved to dismiss RBC’s claims against us that are based on the settlement agreement with the school districts.  The Motion to Dismiss was denied by the court, and we have filed our Answer to RBC’s claims and discovery continues in the case.  We believe we have meritorious legal and factual defenses to the claims asserted by RBC and we intend to vigorously defend those claims.
	EDC Bond Issuance Matter
	In January 2008, our company was the initial purchaser of a $50.0 million bond offering under Rule 144A. The bonds were issued by the Lake of the Torches Economic Development Corporation (“EDC”) in connection with certain new financing for the construction of a proposed new casino, as well as refinancing of indebtedness involving Lac Du Flambeau Band of Lake Superior Chippewa Indians (the “Tribe”). In 2009, Saybrook Tax Exempt Investors LLC, a qualified institutional buyer and the sole bondholder through its special purpose vehicle LDF Acquisition LLC (collectively, “Saybrook”), and Wells Fargo Bank, NA (“Wells Fargo”), indenture trustee for the bonds, brought an action in a Wisconsin federal court against EDC and the Tribe to enforce the bonds after a default by EDC. Our company was not named as a party in that action. In the 2009 action, EDC was successful in its assertion that the bond indenture was void as an unapproved “management contract” under National Indian Gaming Commission regulations, and that accordingly the Tribe’s waiver of sovereign immunity contained in the indenture was void. Although the Wisconsin federal court dismissed the entire 2009 action, the Seventh Circuit Court of Appeals modified the judgment and remanded the case for further proceedings as to enforceability of the bond documents other than the bond indenture against EDC.
	On January 16, 2012, after the remand from the Seventh Circuit Court of Appeals, Saybrook filed a new action in Wisconsin state court naming our company and Stifel as defendants with respect to Stifels’ role as initial purchaser. Saybrook also named as defendants: the Tribe, EDC, and the law firm of Godfrey & Kahn, S.C. (“G&K”) which served as both issuer’s counsel and bond counsel in the transaction. The Wisconsin state-court action seeks to enforce the bonds against EDC and the Tribe and also asserts claims against the defendants based on alleged misrepresentations about the enforceability of the indenture and the bonds and the waiver of sovereign immunity by EDC and the Tribe. In April 2012 Saybrook dismissed the 2009 federal action and filed a new action in Wisconsin federal court alleging nearly identical claims against the same defendants named in the Wisconsin state court action.  The parties agreed to stay the state court action until the federal court ruled on whether it had jurisdiction over the 2012 federal action, and in April 2013 the federal court determined it did not have jurisdiction over the action. That decision by the federal court reactivated the Wisconsin state court action filed in 2012.
	As plaintiff in the state court action, Saybrook alleges that G&K represented in various legal opinions issued in the transaction, as well as in other documents associated with the transaction, that (i) the bonds and indenture were legally enforceable obligations of EDC and (ii) EDC’s waivers of sovereign immunity were valid. The claims asserted against us are for breaches of implied warranties of validity and title, securities fraud and statutory misrepresentation under Wisconsin state law, and intentional and negligent misrepresentations relating to the validity of the bond documents and the Tribe’s waiver of its sovereign immunity. To the extent EDC does not fully perform its obligations to Saybrook pursuant to the bonds, Saybrook seeks a judgment for rescission, restitutionary damages, including the amounts paid by Saybrook for the bonds, and costs; alternatively, Saybrook seeks to recover damages, costs and attorneys’ fees from us.
	After the federal court declined to exercise jurisdiction over the 2012 federal court action and with the state court action reactivated, on April 25, 2013 the Tribe and EDC filed a new lawsuit against Saybrook, our company, Stifel, G&K, and Wells Fargo in the Lac du Flambeau Tribal Court. The Tribal Court action seeks a declaratory judgment that all of the bond documents are void.  This new lawsuit created a jurisdictional conflict between the Tribal Court and the Wisconsin state court that may be resolved by those courts or by the Federal Court in the Federal Action described below.  We filed a Motion to Dismiss the Tribal Court action, which was denied on August 27, 2013, and we have filed our Answer to the lawsuit in the Tribal Court.  On April 29, 2013, we filed a motion to dismiss all of the claims alleged against our company and Stifel brought by Saybrook in the state court action.  That Motion was denied by the State Court, and we have answered the Complaint and filed cross claims against the Tribe and G&K in the State Court.
	On May 24, 2013 we, together with Saybrook, Wells Fargo and G&K, filed an action in a Wisconsin federal court (the “Federal Action” seeking to enjoin the Tribal Court action.  The Tribe and EDC (the “Tribal Parties”) have filed a motion to dismiss or stay the Federal Action. The Tribal Parties’ motion to dismiss or stay was denied on October 29, 2013.  The Tribe appealed the U.S. District Court’s denial of the Motion to Dismiss to the Seventh Circuit Court of Appeals, but the Seventh Circuit dismissed the appeal for lack of appellate jurisdiction on January 13, 2014.  The District Court in the Federal Action has scheduled a hearing for March 14, 2014 on our motion for preliminary injunction to enjoin the Tribal Court action.  Meanwhile, the Tribal Court action and the State Court action were stayed during the pendency of the Tribe’s appeal to the Seventh Circuit, but the stays of those actions expire on February 12, 2014.  While there can be no assurance that we will be successful, based upon currently available information and review with outside counsel, we believe that we have meritorious legal and factual defenses to the matter, and we intend to vigorously defend the substantive claims and the procedural attempt to move the litigation to the Lac du Flambeau Tribal Court.
	Lac Courte Oreilles Tribal Lawsuit
	On December 13, 2012, the Lac Courte Oreilles Band of Lake Superior Chippewa Indians of Wisconsin (the “Tribe”) filed a civil lawsuit against Stifel in the Tribe’s Tribal Court (the “Tribal Lawsuit”). In December 2006, the Tribe issued two series of taxable municipal bonds as a means of raising revenue to fund various projects (the “2006 Bond Transaction”), including the refinancing of two series of bonds the Tribe issued in 2003. The Complaint alleges that we undertook to advise the Tribe regarding its financing options in 2006 but failed to disclose certain information before the 2006 Bond Transaction. On February 19, 2013 we filed a declaratory judgment action in a Wisconsin federal court seeking to establish that the Tribal Court lacks jurisdiction over the Tribal Lawsuit (the “Federal Action”). On February 20, 2013, we filed a motion to dismiss the Tribal Lawsuit, challenging the jurisdiction of the Tribal Court, which motion was denied by the Tribal Court.  The Tribe filed a motion to dismiss the Federal Action.  Shortly thereafter, the Tribe agreed to withdraw its motion to dismiss the Federal Action and agreed to stay the Tribal Lawsuit pending a determination by the Wisconsin federal court as to whether the Tribal Court has jurisdiction over the claims. Basic discovery was taken in the Federal Action, and we filed a summary judgment motion with the U.S. District Court, asking the court for a determination that the Tribal Court does not have jurisdiction over the claims brought by the Tribe.  The summary judgment motion has been fully briefed, and we are awaiting a ruling by the U.S. District Court.  In the event the court does not grant summary judgment a court trial is scheduled for June 23, 2014 to determine whether the Tribal Court has jurisdiction over the claims brought by the Tribe.  While there can be no assurance that we will be successful, based upon currently available information and review with outside counsel, we believe that we have meritorious defenses to the Tribe’s claims and we intend to vigorously defend the allegations.
	Stetson Oil & Gas Ltd. Matter
	In October 2008, Stetson Oil & Gas Ltd. named Thomas Weisel Partners Canada, Inc. (n/k/a Stifel Nicolaus Canada, Inc.) as a defendant in a statement of claim filed in the Ontario Superior Court of Justice.  On March 1, 2013, Stifel Nicolaus Canada received an adverse decision from the Ontario Superior Court of Justice that it had breached an engagement letter with Stetson, dated July 13, 2008.  The decision awarded Stetson approximately $16.0 million plus interest and costs incurred by Stetson in connection with the litigation.  Stifel Nicolaus Canada disagrees with the Court’s decision and is appealing that decision.  Stifel Nicolaus Canada believes it has adequate reserves for what it believes will be the ultimate resolution of this matter.

Regulatory Capital Requirements	'
	NOTE 20 – Regulatory Capital Requirements
	We operate in a highly regulated environment and are subject to capital requirements, which may limit distributions to our company from its subsidiaries. Distributions from our broker-dealer subsidiaries are subject to net capital rules. A broker-dealer that fails to comply with the SEC’s Uniform Net Capital Rule (Rule 15c3-1) may be subject to disciplinary actions by the SEC and self-regulatory organizations, such as FINRA, including censures, fines, suspension, or expulsion. Stifel has chosen to calculate its net capital under the alternative method, which prescribes that their net capital shall not be less than the greater of $1.0 million or two percent of aggregate debit balances (primarily receivables from customers) computed in accordance with the SEC’s Customer Protection Rule (Rule 15c3-3). KBW, CSA, and Miller Buckfire calculate their net capital under the aggregate indebtedness method, whereby their aggregate indebtedness may not be greater than fifteen times their net capital (as defined).
	At December 31, 2013, Stifel had net capital of $368.2 million, which was 58.8% of aggregate debit items and $355.7 million in excess of its minimum required net capital. At December 31, 2013, KBW’s, CSA’s, and Miller Buckfire’s net capital exceeded the minimum net capital required under the SEC rule.
	Our international subsidiaries, SNEL and KBW Limited, are subject to the regulatory supervision and requirements of the Financial Conduct Authority (“FCA”) in the United Kingdom. At December  31, 2013, SNEL’s and KBW Limited’s capital and reserves were in excess of the financial resources requirement under the rules of the FCA.
	Our company, as a bank holding company, and Stifel Bank are subject to various regulatory capital requirements administered by the Federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our company’s and Stifel Bank’s financial results. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, our company and Stifel Bank must meet specific capital guidelines that involve quantitative measures of our assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. Our company’s and Stifel Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.
	Quantitative measures established by regulation to ensure capital adequacy require our company, as a bank holding company, and Stifel Bank to maintain minimum amounts and ratios of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and Tier 1 capital to average assets (as defined). To be categorized as “well capitalized,” our company and Stifel Bank must maintain total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the tables below (in thousands, except ratios).

Employee Incentive, Deferred Compensation, And Retirement Plans [Abstract]	'
Employee Incentive, Deferred Compensation, And Retirement Plans	'
	NOTE 23 – Employee Incentive, Deferred Compensation, and Retirement Plans
	We maintain several incentive stock award plans that provide for the granting of stock options, stock appreciation rights, restricted stock, performance awards, and stock units to our employees. We are permitted to issue new shares under all stock award plans approved by shareholders or to reissue our treasury shares. Awards under our company’s incentive stock award plans are granted at market value at the date of grant. The awards generally vest ratably over a three- to eight-year vesting period..
	All stock-based compensation plans are administered by the Compensation Committee of the Board of Directors (“Compensation Committee”), which has the authority to interpret the plans, determine to whom awards may be granted under the plans, and determine the terms of each award. According to these plans, we are authorized to grant an additional 5.1 million shares at December 31, 2013.
	Stock-based compensation expense included in compensation and benefits expense in the consolidated statements of operations for our company’s incentive stock award plans was $131.8 million,  $51.4 million, and $29.5 million for the years ended December 31, 2013, 2012, and 2011, respectively. The tax benefit related to stock-based compensation recognized in shareholders’ equity was $12.0 million,  $16.7 million, and $24.9 million for the years ended December 31, 2013 and 2012, respectively.
	On closing date of our acquisition of KBW, Inc., certain employees of KBW, Inc. and our company were granted restricted stock or restricted stock units of Stifel as retention. The fair value of the awards issued as retention was $30.6 million. There are no continuing service requirements associated with these restricted stock units, and accordingly were expensed at date of grant. This charge is included in compensation and benefits in the consolidated statement of operations for the year ended December 31, 2013.
	On the closing date of the acquisition of the Knight Capital Fixed Income business, we granted restricted stock units to certain employees as retention. The fair value of the awards issued as retention was $18.7 million. There are no continuing service requirements associated with these restricted stock units, and accordingly were expensed at date of grant. This charge is included in compensation and benefits in the consolidated statement of operations for the year ended December 31, 2013.
	Stock Options
	We have substantially eliminated the use of stock options as a form of compensation. During the year ended December 31, 2013, no options were granted.
	A summary of option activity under the plans as of December 31, 2013, and changes during the year then ended is presented below (in thousands, except exercise price and contractual terms):
		Options		Weighted-average exercise price		Weighted-average remaining contractual term		Aggregate intrinsic value
	Outstanding, December 31, 2012		249	$	19.95
	Granted		-		-
	Exercised		89		7.30
	Forfeited		-		-
	Expired		-		-
	Outstanding, December 31, 2013		338	$	26.99		2.65	$	4,200
	At December 31, 2013, all outstanding options were exercisable. The total intrinsic value of options exercised during the years ended December 31, 2013, 2012, and 2011 was $2.8 million, $19.2 million, and $3.7 million, respectively. The fair value of options vested during the year ended December 31, 2011 was $0.7 million. Cash proceeds from the exercise of stock options were $3.6 million, $4.2 million, and $1.4 million for the years ended December 31, 2013, 2012, and 2011, respectively. Tax benefits realized from the exercise of stock options for the years ended December 31, 2013, 2012, and 2011 were $1.1 million, $7.5 million, and $1.4 million, respectively.
	Stock Units
	A stock unit represents the right to receive a share of common stock from our company at a designated time in the future without cash payment by the employee and is issued in lieu of cash incentive, principally for deferred compensation and employee retention plans. The restricted stock units vest on an annual basis over the next three to eight years and are distributable, if vested, at future specified dates. At December 31, 2013, the total number of stock units outstanding was 17.7 million, of which 8.8 million were unvested.
	A summary of unvested stock unit activity under the plans as of December 31, 2013, and changes during the year then ended is presented below (in thousands, except weighted-average fair value):
		Stock units		Weighted-average grant date fair value
	Unvested, December 31, 2012		6,551	$	36.62
	Granted		6,303		36.71
	Vested		-3,677		37.00
	Cancelled		-333		33.96
	Unvested, December 31, 2013		8,844	$	36.63
	At December 31, 2013, there was unrecognized compensation cost for stock units of $253.4 million, which is expected to be recognized over a weighted-average period of 2.9 years.
	Deferred Compensation Plans
	The Stifel Wealth Accumulation Plan (the “SWAP Plan”) is provided to certain revenue producers, officers, and key administrative employees, whereby a certain percentage of their incentive compensation is deferred as defined by the Plan into company stock units with a 25% matching contribution by our company. Participants may elect to defer up to an additional 15% of their incentive compensation with a 25% matching contribution. Units generally vest over a three- to seven-year period and are distributable upon vesting or at future specified dates. Deferred compensation costs are amortized on a straight-line basis over the vesting period. Elective deferrals are 100% vested. As of December 31, 2013, there were 16.7 million units outstanding under the SWAP Plan.
	Additionally, the SWAP Plan allows Stifel’s financial advisors who achieve certain levels of production, the option to defer a certain percentage of their gross commissions. As stipulated by the SWAP Plan, the financial advisors have the option to: 1) defer 4% of their gross commissions into company stock units with a 25% matching contribution and may elect to defer an additional 1% of gross commissions into company stock units with a 25% matching contribution, or 2) defer up to 2% in mutual funds, which earn a return based on the performance of index mutual funds as designated by our company or a fixed income option. The mutual fund deferral option does not include a company match. Financial advisors have no ownership in the mutual funds. Included in the investments in the consolidated statements of financial condition are investments in mutual funds of $17.0 million and $18.0 million at December 31, 2013 and 2012, respectively, that were purchased by our company to economically hedge, on an after-tax basis, its liability to the financial advisors who choose to base the performance of their return on the index mutual fund option. At December 31, 2013 and 2012, the deferred compensation liability related to the mutual fund option of $14.3 million and $16.6 million, respectively, is included in accrued compensation in the consolidated statements of financial condition.
	In addition, certain financial advisors, upon joining our company, may receive company stock units in lieu of transition cash payments. Deferred compensation related to these awards generally vests over a five- to eight-year period. Deferred compensation costs are amortized on a straight-line basis over the deferral period.
	Profit Sharing and Employee Stock Ownership Plans
	Eligible employees of our company who have met certain service requirements may participate in the Stifel Profit Sharing 401(k) Plan (the “Profit Sharing Plan”). We may match certain employee contributions or make additional contributions to the Profit Sharing Plan at our discretion. Our contributions to the Profit Sharing Plan were $6.4 million, $3.7 million, and $3.6 million for the years ended December 31, 2013, 2012, and 2011, respectively.
	We had an internally leveraged employee stock ownership plan (“ESOP”) in which qualified employees of our company, as defined in the ESOP, participated. We made annual contributions to the ESOP in an amount determined by the Compensation Committee on behalf of all eligible employees based upon the relationship of individual compensation to total compensation. The Employee Stock Ownership Plan was terminated by our company during the year ended December 31, 2013. Compensation expense of $0.4 million, $1.7 million, and $1.7 million relating to the ESOP was recorded for the years ended December 31, 2013, 2012, and 2011, respectively.

Off-Balance Sheet Credit Risk [Abstract]	'
Off-Balance Sheet Credit Risk	'
	NOTE 24 – Off-Balance Sheet Credit Risk
	In the normal course of business, we execute, settle, and finance customer and proprietary securities transactions. These activities expose our company to off-balance sheet risk in the event that customers or other parties fail to satisfy their obligations.
	In accordance with industry practice, securities transactions generally settle within three business days after trade date. Should a customer or broker fail to deliver cash or securities as agreed, we may be required to purchase or sell securities at unfavorable market prices.
	We borrow and lend securities to facilitate the settlement process and finance transactions, utilizing customer margin securities held as collateral. We monitor the adequacy of collateral levels on a daily basis. We periodically borrow from banks on a collateralized basis, utilizing firm and customer margin securities in compliance with SEC rules. Should the counterparty fail to return customer securities pledged, we are subject to the risk of acquiring the securities at prevailing market prices in order to satisfy our customer obligations. We control our exposure to credit risk by continually monitoring our counterparties’ positions, and where deemed necessary, we may require a deposit of additional collateral and/or a reduction or diversification of positions. Our company sells securities it does not currently own (short sales) and is obligated to subsequently purchase such securities at prevailing market prices. We are exposed to risk of loss if securities prices increase prior to closing the transactions. We control our exposure to price risk from short sales through daily review and setting position and trading limits.
	We manage our risks associated with the aforementioned transactions through position and credit limits and the continuous monitoring of collateral. Additional collateral is required from customers and other counterparties when appropriate.
	We have accepted collateral in connection with resale agreements, securities borrowed transactions, and customer margin loans. Under many agreements, we are permitted to sell or repledge these securities held as collateral and use these securities to enter into securities lending arrangements or to deliver to counterparties to cover short positions. At December 31, 2013 and 2012, the fair value of securities accepted as collateral where we are permitted to sell or repledge the securities was $1.2 billion and $965.8 million, respectively, and the fair value of the collateral that had been sold or repledged was $263.8 million and $140.3 million, respectively.
	We enter into interest rate derivative contracts to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Our derivative financial instruments are principally used to manage differences in the amount, timing, and duration of our known or expected cash payments related to certain variable-rate affiliated deposits.  Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for us making fixed-rate payments. Our interest rate hedging strategies may not work in all market environments and, as a result, may not be effective in mitigating interest rate risk.
	Derivatives’ notional contract amounts are not reflected as assets or liabilities in the consolidated statements of financial condition. Rather, the market, or fair value, of the derivative transactions are reported in the consolidated statements of financial condition as other assets or accounts payable and accrued expenses, as applicable.
	For a complete discussion of our activities related to derivative instruments, see Note 15 in the notes to our consolidated financial statements.
	In the ordinary course of business, Stifel Bank has commitments to originate loans, standby letters of credit, and lines of credit. Commitments to originate loans are agreements to lend to a customer as long as there is no violation of any condition established by the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a portion of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash commitments. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if necessary, is based on the credit evaluation of the counterparty. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, commercial real estate, and residential real estate.
	At December 31, 2013 and 2012, Stifel Bank had outstanding commitments to originate loans aggregating $66.8 million and $241.5 million, respectively. The commitments extended over varying periods of time, with all commitments at December  31, 2013 scheduled to be disbursed in the following three months.
	Through Stifel Bank, in the normal course of business, we originate residential mortgage loans and sell them to investors. We may be required to repurchase mortgage loans that have been sold to investors in the event there are breaches of certain representations and warranties contained within the sales agreements. We may be required to repurchase mortgage loans that were sold to investors in the event that there was inadequate underwriting or fraud, or in the event that the loans become delinquent shortly after they are originated. We also may be required to indemnify certain purchasers and others against losses they incur in the event of breaches of representations and warranties and in various other circumstances, and the amount of such losses could exceed the repurchase amount of the related loans. Consequently, we may be exposed to credit risk associated with sold loans.
	Standby letters of credit are irrevocable conditional commitments issued by Stifel Bank to guarantee the performance of a customer to a third party. Financial standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing, and similar transactions. Performance standby letters of credit are issued to guarantee performance of certain customers under non-financial contractual obligations. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. Should Stifel Bank be obligated to perform under the standby letters of credit, it may seek recourse from the customer for reimbursement of amounts paid. At December 31, 2013 and 2012, Stifel Bank had outstanding letters of credit totaling $5.1 million and $10.5 million, respectively. All of the standby letters of credit commitments at December  31,  2013 have expiration terms that are less than one year.
	Lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Lines of credit generally have fixed expiration dates. Stifel Bank uses the same credit policies in granting lines of credit as it does for on-balance sheet instruments. At December 31, 2013 and 2012, Stifel Bank had granted unused lines of credit to commercial and consumer borrowers aggregating $282.0 million and $220.1 million, respectively.

	Our net deferred tax asset at December 31, 2013, includes net operating loss carryforwards of $242.6 million that expire between 2014 and 2024. A valuation allowance is recorded to the extent that it is more likely than not that any portion of the deferred tax asset will not be realized. The valuation allowance was increased by $4.3 million to adjust the tax benefit of certain state and foreign net operating loss carryforwards and state tax credits to the amount that we have determined is more likely than not to be realized. We believe the realization of the remaining net deferred tax asset of $243.6 million is more likely than not based on the ability to carry back losses against prior year taxable income and expectations of future taxable income.
	The current tax payable, included in accounts payable and accrued expenses, is $30.1 million and $19.1 million as of December 31, 2013 and 2012, respectively.
	We have recorded income tax expense at U.S. tax rates on all profits, except for undistributed profits of our foreign subsidiaries that are considered indefinitely reinvested. Determination of the amount of unrecognized deferred tax liability related to indefinitely reinvested profits is not feasible. If management’s intentions or U.S. tax laws change in the future, there may be a significant impact on the provision for income taxes to record a change in the tax liability in the period the change occurs.
	Uncertain Tax Positions
	As of December 31, 2013 and 2012, we had $5.2 million and $1.8 million, respectively, of gross unrecognized tax benefits, all of which, if recognized, would impact the effective tax rate. We recognize interest and penalties related to uncertain tax positions in provision for income taxes/(benefits) in the consolidated statements of operations. As of December 31, 2013 and 2012, we had accrued interest and penalties of $1.0 million and $1.0 million, respectively, before benefit of federal tax deduction, included in accounts payable and accrued expenses on our consolidated statements of financial condition. The amount of interest and penalties recognized on our consolidated statements of operations for the years ended December 31, 2013, 2012, and 2011 was not significant.
	The following table summarizes the activity related to our company’s unrecognized tax benefits from January 1, 2011 to December 31, 2013 (in thousands):

We file income tax returns with the U.S. federal jurisdiction, various states, and certain foreign jurisdictions. We are not subject to U.S. federal, certain state and local, or non-U.S. income tax examination by tax authorities for taxable years before 2010.
There is a reasonable possibility that the unrecognized tax benefits will change within the next 12 months as a result of the expiration of various statutes of limitations or for the resolution of U.S. federal and state examinations, but we do not expect this change to be material to the consolidated financial statements.

Earnings Per Share [Abstract]	'
Earnings Per Share	'
	NOTE 27 –  Earnings Per Share (“EPS”)
	Basic EPS is computed by dividing earnings available to common shareholders by the weighted-average number of common shares outstanding. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. Diluted earnings per share include dilutive stock options and stock units under the treasury stock method.
	The following table sets forth the computation of basic and diluted earnings per share for the years ended December 31, 2013, 2012, and 2011 (in thousands, except per share data):
		Year Ended December 31,
		2013		2012		2011
	Income from continuing operations		172,907		145,296		84,269

	Dilutive effect of stock options and units		9,936		9,374		10,640
	Average shares used in diluted computation:		73,504		62,937		63,058

	Earnings per diluted common share
	Income from continuing operations	$	2.35	$	2.31	$	1.34
	Loss from discontinued operations		-0.15		-0.11		-
	Earnings per diluted common share	$	2.20	$	2.20	$	1.34
	(1)Diluted earnings per share is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Diluted earnings per share include stock options and units.
	For the years ended December 31, 2013, 2012, and 2011, the anti-dilutive effect from restricted stock units was immaterial.

Shareholders' Equity	'
	NOTE 28 –  Shareholders’ Equity
	Share Repurchase Program
	We have an ongoing authorization from the Board of Directors to repurchase our common stock in the open market or in negotiated transactions. At December 31, 2013, the maximum number of shares that may yet be purchased under this plan was 3.5 million. The repurchase program has no expiration date.  These purchases may be made on the open market or in privately negotiated transactions, depending upon market conditions and other factors. Repurchased shares may be used to meet obligations under our employee benefit plans and for general corporate purposes. During the years ended December 31, 2013, 2012, and 2011, we repurchased $13.7 million, $11.4 million, and $48.5 million, or 0.4 million, 0.4 million, and 1.7 million shares, respectively, using existing Board authorizations at an average price of $31.75, $30.35, and $28.12 per share, respectively, to meet obligations under our company’s employee benefit plans and for general corporate purposes.
	Issuance of Shares
	During the years ended December 31, 2013, 2012, and 2011, we issued 6.7 million,  2.3 million, and 1.7 million shares , respectively, which included the reissuance of 0.5 million, 2.1 million, and 1.7 million shares from treasury, respectively.
	Share issuances during the year ended December 31, 2013, were primarily a result of the vesting and exercise transactions under our incentive stock award plans, and shares issued as part of the purchase consideration in our acquisition of KBW, Inc. Share issuances during the year ended December 31, 2012, were primarily a result of the vesting and exercise transactions under our incentive stock award plans, the exercise of warrants that were issued as part of the Ryan Beck acquisition, and shares issued as part of the purchase consideration in our acquisition of Miller Buckfire. Share issuances during the year ended December 31, 2011, were primarily a result of the vesting and exercise transactions under our incentive stock award plans and the acquisition of Stone & Youngberg. See Note 3 in the notes to our consolidated financial statements for additional information regarding our acquisitions.
	As partial consideration of the purchase price of Ryan Beck, we issued shares of common stock and five-year immediately exercisable warrants to purchase up to 1.13 million shares of our common stock at an exercise price of $16.00 per share. There were no warrants outstanding at December 31, 2012. At December 31, 2011, there were 34,328 warrants outstanding to purchase shares of our common stock at an exercise price of $16.00.
	On October 1, 2011, we acquired Stone & Youngberg. As part of the purchase consideration, at the close of the acquisition, we issued 0.2 million shares of our common stock. The shares were issued from treasury.
	On December 20, 2012, we acquired Miller Buckfire. As part of the purchase consideration, at the close of the acquisition, we issued 0.1 million shares of our common stock.
	On February 15, 2013, we issued 6.7 million shares related to the purchase of KBW, Inc. See Note 3 in the notes to our consolidated financial statements for additional information regarding the acquisition of KBW, Inc.

Variable Interest Entities [Abstract]	'
Variable Interest Entities	'
	NOTE 29 – Variable Interest Entities
	The determination as to whether an entity is a VIE is based on the structure and nature of the entity. We also consider other characteristics, such as the ability to influence the decision-making relative to the entity’s activities and how the entity is financed. The determination as to whether we must consolidate a VIE is based on whether we are the primary beneficiary for certain entities. The primary beneficiary determination is based on a qualitative analysis of the VIE’s expected losses and expected residual returns. This analysis includes a review of, among other factors, the VIE’s capital structure, contractual terms, which interests create or absorb variability, related party relationships, and the design of the VIE. For other entities, the determination as to whether we must consolidate the VIE is based on an analysis of the power to direct the activities of the VIE as well as the obligation to absorb losses or benefits that could potentially be significant to the entity. Where qualitative analyses are not conclusive, we perform a quantitative analysis. Our company’s involvement with VIEs is limited to entities used as investment vehicles and private equity funds, the establishment of Stifel Financial Capital Trusts, and our issuance of a convertible promissory note.
	We have formed several non-consolidated investment funds with third-party investors that are typically organized as limited liability companies (“LLCs”) or limited partnerships. These partnerships and LLCs have assets of approximately $246.7 million at December 31, 2013. For those funds where we act as the general partner, our company’s economic interest is generally limited to management fee arrangements as stipulated by the fund operating agreements. We have generally provided the third-party investors with rights to terminate the funds or to remove us as the general partner. Management fee revenue earned by our company was insignificant during the years ended December 31, 2013, 2012, and 2011. In addition, our direct investment interest in these entities is insignificant at December 31, 2013 and 2012.
	Thomas Weisel Capital Management LLC, a subsidiary of our company, acts as the general partner of a series of investment funds in venture capital and fund of funds and manages investment funds that are active buyers of secondary interests in private equity funds, as well as portfolios of direct interests in venture-backed companies. These partnerships have combined assets of approximately $245.1 million at December 31, 2013. We hold variable interests in these funds as a result of our company’s rights to receive management fees. Our company’s investment in and additional capital commitments to the private equity funds are also considered variable interests. The additional capital commitments are subject to call at a later date and are limited in amount. Our exposure to loss is limited to our investments in, advances and commitments to, and receivables due from these funds, and that exposure is $2.0 million at December 31, 2013. Management fee revenue earned by our company was insignificant during the years ended December 31, 2013, 2012, and 2011.
	For the entities noted above that were determined to be VIEs, we have concluded that we are not the primary beneficiary and therefore we are not required to consolidate these entities. Additionally, for certain other entities we reviewed other relevant accounting guidance, which states the general partner in a limited partnership is presumed to control that limited partnership. The presumption may be overcome if the limited partners have either: (1) the substantive ability to dissolve the limited partnership or otherwise remove the general partner without cause, or (2) substantive participating rights, which provide the limited partners with the ability to effectively participate in significant decisions that would be expected to be made in the ordinary course of the limited partnership’s business and thereby preclude the general partner from exercising unilateral control over the partnership. If the criteria are not met, the consolidation of the partnership or limited liability company is required. Based on our evaluation of these entities, we determined that these entities do not require consolidation.
	Debenture to Stifel Financial Capital Trusts
	We have completed private placements of cumulative trust preferred securities through Stifel Financial Capital Trust II, Stifel Financial Capital Trust III, and Stifel Financial Capital Trust IV (collectively, the “Trusts”). The Trusts are non-consolidated wholly owned business trust subsidiaries of our company and were established for the limited purpose of issuing trust securities to third parties and lending the proceeds to our company.
	The trust preferred securities represent an indirect interest in junior subordinated debentures purchased from our company by the Trusts, and we effectively provide for the full and unconditional guarantee of the securities issued by the Trusts. We make timely payments of interest to the Trusts as required by contractual obligations, which are sufficient to cover payments due on the securities issued by the Trusts, and believe that it is unlikely that any circumstances would occur that would make it necessary for our company to make payments related to these Trusts other than those required under the terms of the debenture agreements and the trust preferred securities agreements. The Trusts were determined to be VIEs because the holders of the equity investment at risk do not have adequate decision-making ability over the Trust’s activities. Our investment in the Trusts is not a variable interest, because equity interests are variable interests only to the extent that the investment is considered to be at risk. Because our investment was funded by the Trusts, it is not considered to be at risk.
	Interest in FSI Group, LLC (“FSI”)
	We have provided financing of $18.0 million in the form of a convertible promissory note to FSI, a limited liability company specializing in investing in banks, thrifts, insurance companies, and other financial services firms. In February 2013, the convertible promissory note was amended and restated. The convertible promissory note matures in April 2018; however, FSI has three 5 year extension options. The note is convertible at our election into a 49.9% interest in FSI only after the last extension option. The convertible promissory note has a minimum coupon rate equal to 8% per annum plus additional interest related to certain defined cash flows of the business, not to exceed 18% per annum. As we do not hold the power to direct the activities of FSI nor to absorb a majority of the expected losses, or receive a majority of the expected benefits, it was determined that we are not required to consolidate this entity.
	Our company’s exposure to loss is limited to the carrying value of the note with FSI at December 31, 2013, of $18.0 million, which is included in other assets in the consolidated statements of financial condition. Our company had no liabilities related to this entity at December 31, 2013. We have the discretion to make additional capital contributions. We have not provided financial or other support to FSI that we were not previously contractually required to provide as of December 31,  2013. Our company’s involvement with FSI has not had a material effect on our consolidated financial position, operations, or cash flows.

	We evaluate subsequent events that have occurred after the balance sheet date but before the financial statements are issued. There are two types of subsequent events: (1) recognized, or those that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements, and (2) non-recognized, or those that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. Based on the evaluation, we did not identify any recognized subsequent events that would have required adjustment to the consolidated financial statements.

	Stifel Financial Corp.  (the “Parent”), through its wholly owned subsidiaries, principally Stifel, Nicolaus & Company, Incorporated (“Stifel”), Stifel Bank & Trust (“Stifel Bank”), Stifel Nicolaus Europe Limited (“SNEL”), Century Securities Associates, Inc. (“CSA”), Keefe, Bruyette & Woods, Inc. (“KBW”), Keefe, Bruyette & Woods Limited (“KBW Limited”), and Miller Buckfire & Co. LLC (“Miller Buckfire”), is principally engaged in retail brokerage; securities trading; investment banking; investment advisory; retail, consumer, and commercial banking; and related financial services. We have offices throughout the United States and three European cities. Our major geographic area of concentration is the Midwest and Mid-Atlantic regions, with a growing presence in the Northeast, Southeast and Western United States. Our company’s principal customers are individual investors, corporations, municipalities, and institutions.
Basis Of Presentation	'
	Our Canadian subsidiary, Stifel Nicolaus Canada, Inc. (“SN Canada”) ceased business operations as of September 30, 2013. The results of SN Canada, previously reported in the Institutional Group segment, are classified as discontinued operations for all periods presented. See Note 4 to our consolidated financial statements for further discussion of our discontinued operations.
	Basis of Presentation
	The consolidated financial statements include Stifel Financial Corp. and its wholly owned subsidiaries, principally Stifel Nicolaus and Stifel Bank. All material intercompany balances and transactions have been eliminated. Unless otherwise indicated, the terms “we,” “us,” “our,” or “our company” in this report refer to Stifel Financial Corp. and its wholly owned subsidiaries.
	The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles, which require management to make certain estimates and assumptions that affect the reported amounts. We consider significant estimates, which are most susceptible to change and impacted significantly by judgments, assumptions, and estimates, to be: valuation of financial instruments and investments in partnerships; accrual for contingencies; allowance for loan losses; derivative instruments and hedging activities; fair value of goodwill and intangible assets; provision for income taxes and related tax reserves; and forfeitures associated with stock-based compensation. Actual results could differ from those estimates.
	On March 7, 2011, our Board approved a 50% stock dividend, in the form of a three-for-two stock split, of our common stock payable on April 5, 2011, to shareholders of record as of March 22, 2011. All share and per share information has been retroactively adjusted to reflect the stock split.
	Certain amounts from prior periods have been reclassified to conform to the current period’s presentation. The effect of these reclassifications on our company’s previously reported consolidated financial statements was not material.
Consolidation Policies	'
	Consolidation Policies
	The consolidated financial statements include the accounts of Stifel Financial Corp. and its subsidiaries. We also have investments or interests in other entities for which we must evaluate whether to consolidate by determining whether we have a controlling financial interest or are considered to be the primary beneficiary. In determining whether to consolidate these entities, we evaluate whether the entity is a voting interest entity or a variable interest entity (“VIE”).
Voting Interest Entity	'
	Voting Interest Entity. Voting interest entities are entities that have (i) total equity investment at risk sufficient to fund expected future operations independently, and (ii) equity holders who have the obligation to absorb losses or receive residual returns and the right to make decisions about the entity’s activities. We consolidate voting interest entities when we determine that there is a controlling financial interest, usually ownership of all, or a majority of, the voting interest.
Variable Interest Entity	'
	Variable Interest Entity. VIEs are entities that lack one or more of the characteristics of a voting interest entity. We are required to consolidate certain VIEs in which we have the power to direct the activities of the entity and the obligation to absorb significant losses or receive significant benefits. In other cases, we consolidate VIEs when we are deemed to be the primary beneficiary. The primary beneficiary is defined as the entity that has a variable interest, or a combination of variable interests, that maintains control and receives benefits or will absorb losses that are not pro rata with its ownership interests. See Note 28 for additional information on VIEs.

Significant Accounting Policies [Abstract]	'
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	We consider money market mutual funds and highly liquid investments with original maturities of three months or less that are not restricted or segregated to be cash equivalents. Cash and cash equivalents include money market mutual funds, deposits with banks, certificates of deposit, and federal funds sold. Cash and cash equivalents also include balances that Stifel Bank maintains at the Federal Reserve Bank.
Restricted Cash	'
	Restricted Cash
	Restricted cash consists of cash used as collateral for letters of credit related to certain lease commitments.
Cash Segregated For Regulatory Purposes	'
	Cash Segregated for Regulatory Purposes
	Our broker-dealer subsidiaries are subject to Rule 15c3-3 under the Securities Exchange Act of 1934, which requires our company to maintain cash or qualified securities in a segregated reserve account for the exclusive benefit of its clients. In accordance with Rule 15c3-3, our company has portions of its cash segregated for the exclusive benefit of clients at December 31, 2013.
Brokerage Client Receivables, Net	'
	Brokerage Client Receivables, Net
	Brokerage client receivables include receivables of our company’s broker-dealer subsidiaries, which represent amounts due on cash and margin transactions and are generally collateralized by securities owned by clients. Brokerage client receivables, primarily consisting of floating-rate loans collateralized by customer-owned securities, are charged interest at rates similar to other such loans made throughout the industry.  The receivables are reported at their outstanding principal balance net of allowance for doubtful accounts. When a brokerage client receivable is considered to be impaired, the amount of the impairment is generally measured based on the fair value of the securities acting as collateral, which is measured based on current prices from independent sources, such as listed market prices or broker-dealer price quotations. Securities owned by customers, including those that collateralize margin or other similar transactions, are not reflected in the consolidated statements of financial condition.
Securities Borrowed and Loaned	'
	Securities Borrowed and Securities Loaned
	Securities borrowed require our company to deliver cash to the lender in exchange for securities and are included in receivables from brokers, dealers, and clearing organizations in the consolidated statements of financial condition. For securities loaned, we receive collateral in the form of cash in an amount equal to the market value of securities loaned. Securities loaned are included in payables to brokers, dealers, and clearing organizations in the consolidated statements of financial condition. We monitor the market value of securities borrowed and loaned on a daily basis, with additional collateral obtained or refunded as necessary. Fees received or paid are recorded in interest revenue or interest expense.
	Substantially all of these transactions are executed under master netting agreements, which gives us right of offset in the event of counterparty default; however, such receivables and payables with the same counterparty are not set-off in the consolidated statements of financial condition.
Securities Purchased Under Agreement to Resell	'
	Securities Purchased Under Agreements to Resell
	Securities purchased under agreements to resell (“resale agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We obtain control of collateral with a market value equal to or in excess of the principal amount loaned and accrued interest under resale agreements. As of December 31, 2013, we have entered into these agreements with one major financial institution. These agreements are short-term in nature and are collateralized by U.S. government agency securities. We value collateral on a daily basis, with additional collateral obtained when necessary to minimize the risk associated with this activity.
Financial Instruments	'
	Financial Instruments
	We measure certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents, financial instruments owned, available-for-sale securities, investments, financial instruments sold, but not yet purchased, and derivatives. Other than those separately discussed in the notes to the consolidated financial statements, the remaining financial instruments are generally short-term in nature, and their carrying values approximate fair value.
	The fair value of a financial instrument is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., “the exit price”) in an orderly transaction between market participants at the measurement date. We have categorized our financial instruments measured at fair value into a three-level classification in accordance with Topic 820, “Fair Value Measurement,” which established a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs reflect our assumptions that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the transparency of inputs as follows:
	Level 1 – Quoted prices (unadjusted) are available in active markets for identical assets or liabilities as of the measurement date. A quoted price for an identical asset or liability in an active market provides the most reliable fair value measurement, because it is directly observable to the market.
	Level 2 – Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the measurement date. The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, derivative instruments whose fair value have been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed.
	Level 3 – Instruments that have little to no pricing observability as of the measurement date. These financial instruments do not have two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation.
	Valuation of Financial Instruments
	When available, we use observable market prices, observable market parameters, or broker or dealer prices (bid and ask prices) to derive the fair value of financial instruments. In the case of financial instruments transacted on recognized exchanges, the observable market prices represent quotations for completed transactions from the exchange on which the financial instrument is principally traded.
	A substantial percentage of the fair value of our financial instruments owned, available-for-sale securities, investments, and financial instruments sold, but not yet purchased, are based on observable market prices, observable market parameters, or derived from broker or dealer prices. The availability of observable market prices and pricing parameters can vary from product to product. Where available, observable market prices and pricing or market parameters in a product may be used to derive a price without requiring significant judgment. In certain markets, observable market prices or market parameters are not available for all products, and fair value is determined using techniques appropriate for each particular product. These techniques involve some degree of judgment.
	For investments in illiquid or privately held securities that do not have readily determinable fair values, the determination of fair value requires us to estimate the value of the securities using the best information available. Among the factors we consider in determining the fair value of investments are the cost of the investment, terms and liquidity, developments since the acquisition of the investment, the sales price of recently issued securities, the financial condition and operating results of the issuer, earnings trends and consistency of operating cash flows, the long-term business potential of the issuer, the quoted market price of securities with similar quality and yield that are publicly traded, and other factors generally pertinent to the valuation of investments. In instances where a security is subject to transfer restrictions, the value of the security is based primarily on the quoted price of a similar security without restriction but may be reduced by an amount estimated to reflect such restrictions. The fair value of these investments is subject to a high degree of volatility and may be susceptible to significant fluctuation in the near term, and the differences could be material.
	The degree of judgment used in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Pricing observability is impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, and the characteristics specific to the transaction. Financial instruments with readily available active quoted prices for which fair value can be measured from actively quoted prices generally will have a higher degree of pricing observability and a lesser degree of judgment used in measuring fair value. Conversely, financial instruments rarely traded or not quoted will generally have less, or no, pricing observability and a higher degree of judgment used in measuring fair value. See Note 6 for additional information on how we value our financial instruments.
Loan Classification	'
	Loan Classification
	We classify loans based on our investment strategy and management’s assessment of our intent and ability to hold loans for the foreseeable future or until maturity. Management’s intent and ability with respect to certain loans may change from time to time depending on a number of factors, including economic, liquidity, and capital conditions. The accounting and measurement framework for loans differs depending on the loan classification. The classification criteria and accounting and measurement framework for bank loans and loans held for sale are described below.
	Bank Loans and Allowance for Loan Losses
	Bank loans consist of commercial and residential mortgage loans, home equity loans, stock-secured loans, construction loans, and commercial and industrial and consumer loans originated by Stifel Bank. Bank loans include those loans that management has the intent and ability to hold and are recorded at outstanding principal adjusted for any charge-offs, allowance for loan losses, and deferred origination fees and costs. Loan origination costs, net of fees, are deferred and recognized over the contractual life of the loan as an adjustment of yield using the interest method. Bank loans are generally collateralized by real estate, real property, marketable securities, or other assets of the borrower. Interest income is recognized using the effective interest rate method, which is based upon the respective interest rates and the average daily asset balance.
	We regularly review the loan portfolio and have established an allowance for loan losses for inherent losses estimated to have occurred in the loan portfolio through a provision for loan losses charged to other operating expenses in the consolidated statements of operations. In providing for the allowance for loan losses, we consider historical loss experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available.
	Loans Held for Sale
	Loans that we intend to sell or for which we do not have the ability and intent to hold for the foreseeable future are classified as held for sale. Loans held for sale consist of fixed-rate and adjustable-rate residential real estate mortgage loans intended for sale. Loans held for sale are stated at lower of cost or market value. Declines in market value below cost and any gains or losses on the sale of these assets are recognized in other revenues in the consolidated statements of operations. Market value is determined based on prevailing market prices for loans with similar characteristics or on sale contract prices. Deferred fees and costs related to these loans are not amortized but are recognized as part of the cost basis of the loan at the time it is sold. Because loans held for sale are reported at lower of cost or market value, an allowance for loan losses is not established for loans held for sale.
Impaired Loans	'
	Impaired Loans
	A loan is considered impaired when, based on current information and events, it is probable that the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement will not be collectible. Factors considered in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. We determine the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed.
	Once a loan is determined to be impaired, when principal or interest becomes 90 days past due or when collection becomes uncertain, the accrual of interest and amortization of deferred loan origination fees is discontinued (“non-accrual status”) and any accrued and unpaid interest income is reversed. Loans placed on non-accrual status are returned to accrual status when all delinquent principal and interest payments are collected and the collectibility of future principal and interest payments is reasonably assured. Loan losses are charged against the allowance when we believe the uncollectibility of a loan balance is certain. Subsequent recoveries, if any, are credited to the allowance for loan losses.
	Large groups of smaller balance homogenous loans are collectively evaluated for impairment. Accordingly, we do not separately identify individual consumer and residential loans for impairment measurements. Impairment is measured on a loan-by-loan basis for non-homogeneous loans, and a specific allowance is established for individual loans determined to be impaired. Impairment is measured by comparing the carrying value of the impaired loan to the present value of its expected cash flow discounted at the loan's effective interest rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent.
Other Real Estate Owned	'
	Other Real Estate Owned
	Assets acquired through, or in lieu of, loan foreclosure by Stifel Bank are held for sale and initially recorded at fair value, less estimated cost to sell, at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed and the assets are carried at the lower of carrying amount or fair value less cost to sell. These valuations are performed by a third-party appraisal firm. Other real estated owned is included in other assets in the consolidated statements of financial condition. Revenue and expense from operations and changes in the valuation allowance are included in other income or other operating expense in the consolidated statements of operations.
Investments	'
	Investments
	Our broker-dealer subsidiaries report changes in fair value of marketable and non-marketable securities in other income in the consolidated statements of operations. The fair value of marketable investments is generally based on either quoted market or dealer prices. The fair value of non-marketable securities is based on management’s estimate using the best information available, which generally consists of quoted market prices for similar securities and internally developed discounted cash flow models.
	Investments in the consolidated statements of financial condition contain investments in securities that are marketable and securities that are not readily marketable. These investments are not included in our broker-dealer trading inventory or available-for-sale or held-to-maturity portfolios and represent the acquiring and disposing of debt or equity instruments for our benefit.
Fixed Assets	'
	Fixed Assets
	Office equipment is depreciated on an accelerated basis over the estimated useful life of the asset of two to seven years. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the term of the lease. Buildings and building improvements are amortized on a straight-line basis over the estimated useful life of the asset of three to thirty-nine years. Depreciation expense is recorded in occupancy and equipment rental expense in the consolidated statements of operations. Office equipment, leasehold improvements, and property are stated at cost net of accumulated depreciation and amortization in the consolidated statements of financial condition. Office equipment is reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.
Goodwill and Intangible Assets	'
	Goodwill and Intangible Assets
	Goodwill represents the cost of acquired businesses in excess of the fair value of the related net assets acquired. We test goodwill for impairment on an annual basis and on an interim basis when certain events or circumstances exist. We test for impairment at the reporting unit level, which is generally at the level of or one level below our company’s business segments. For both the annual and interim tests, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If after assessing the totality of events or circumstances, we determine it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then performing the two-step impairment test is not required. However, if we conclude otherwise, we are then required to perform the first step of the two-step impairment test. Goodwill impairment is determined by comparing the estimated fair value of a reporting unit with its respective carrying value. If the estimated fair value exceeds the carrying value, goodwill at the reporting unit level is not deemed to be impaired. If the estimated fair value is below carrying value, however, further analysis is required to determine the amount of the impairment. Additionally, if the carrying value of a reporting unit is zero or a negative value and it is determined that it is more likely than not the goodwill is impaired, further analysis is required. The estimated fair values of the reporting units are derived based on valuation techniques we believe market participants would use for each of the reporting units. We have elected July 31 as our annual impairment testing date.
	Identifiable intangible assets, which are amortized over their estimated useful lives, are tested for potential impairment whenever events or changes in circumstances suggest that the carrying value of an asset or asset group may not be fully recoverable.
Loan And Advances	'
	Loans and Advances
	We offer transition pay, principally in the form of upfront loans, to financial advisors and certain key revenue producers as part of our company’s overall growth strategy. These loans are generally forgiven by a charge to compensation and benefits over a five- to ten-year period if the individual satisfies certain conditions, usually based on continued employment and certain performance standards. We monitor and compare individual financial advisor production to each loan issued to ensure future recoverability. If the individual leaves before the term of the loan expires or fails to meet certain performance standards, the individual is required to repay the balance. In determining the allowance for doubtful receivables from former employees, management considers the facts and circumstances surrounding each receivable, including the amount of the unforgiven balance, the reasons for the terminated employment relationship, and the former employees’ overall financial situation.
Securities Sold Under Agreements To Repurchase	'
	Securities Sold Under Agreements to Repurchase
	Securities sold under agreements to repurchase (“repurchase agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We make delivery of securities sold under agreements to repurchase and monitor the value of collateral on a daily basis. When necessary, we will deliver additional collateral.
Derivative Instruments And Hedging Activitied	'
	Derivative Instruments and Hedging Activities
	We recognize all of our derivative instruments at fair value as either assets or liabilities in the consolidated statements of financial condition. These instruments are recorded in other assets or accounts payable and accrued expenses in the consolidated statements of financial condition and in the operating section of the consolidated statements of cash flows as increases or decreases of other assets and accounts payable and accrued expenses. Our company’s policy is not to offset fair value amounts recognized for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral arising from derivative instruments recognized at fair value executed with the same counterparty under master netting arrangements. The accounting for changes in the fair value (i.e., gains and losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments under Topic 815, “Derivatives and Hedging,” we must also designate the hedging instrument or transaction, based upon the exposure being hedged.
	For derivative instruments that are designated and qualify as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income, net of tax, and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any, is recognized in current earnings during the period of change. We do not use derivatives for trading or speculative purposes and, at December 31, 2013, do not have any derivatives that are not designated in qualifying cash flow hedging relationships. See Note 15 for additional details.
Revenue Recognition	'
	Revenue Recognition
	Customer securities transactions are recorded on a settlement date basis, with related commission revenues and expenses recorded on a trade date basis. Commission revenues are recorded as the amount charged to the customer, which, in certain cases, may include varying discounts. Principal securities transactions are recorded on a trade date basis. We distribute our proprietary equity research products to our client base of institutional investors at no charge. These proprietary equity research products are accounted for as a cost of doing business.
	Investment banking revenues, which include underwriting fees, management fees, advisory fees, and sales credits earned in connection with the distribution of the underwritten securities, are recorded when services for the transactions are completed under the terms of each engagement. Expenses associated with such transactions are deferred until the related revenue is recognized or the engagement is otherwise concluded. Investment banking revenues are presented net of related unreimbursed expenses. Expenses related to investment banking deals not completed are recognized as non-interest expenses in the consolidated statements of operations. For the periods presented, there were no significant expenses recognized for incomplete transactions. We have not recognized any incentive income that is subject to contingent repayments.
	Asset management and service fees are recorded when earned, based on the period-end assets in the accounts, and consist of customer account service fees, per account fees (such as IRA fees), and wrap fees on managed accounts.
	We earn fees from the investment partnerships that we manage or of which we are a general partner. Such management fees are generally based on the net assets or committed capital of the underlying partnerships. We have agreed, in certain cases, to waive management fees, in lieu of making a cash contribution, in satisfaction of our general partner investment commitments to the investment partnerships. In these cases, we generally recognize our management fee revenues at the time when we are allocated a special profit interest in realized gains from these partnerships.
Direct Financing And Operating Leases	'
	Direct Financing and Operating Leases
	The net investment in direct financing leases resulting from our acquisition of East Shore Aircraft LLC (“East Shore”) is included in other assets in the consolidated balance sheets and consists of the present values of the sum of the future minimum lease payments and estimated residual value of the leased assets. Revenue consists of interest earned on the net investment and is recognized over the lease term as a constant percentage return thereon. The net investment in property on operating leases is included in fixed assets in the consolidated balance sheets. Depreciation is recognized, on the straight-line basis, over the lease term to the estimated residual value. Operating lease revenue is recorded on a straight-line basis and is recognized over the lease term in other income. Estimated residual values are established at lease inception utilizing contract terms, past customer experience, and general market data and are reviewed and adjusted, if necessary, on an annual basis. See Note 3 – Acquisitions further details.
	We had a net investment in direct financing leases of $53.7 million at December 31, 2012, which is included in other assets in the consolidated statements of financial condition. This net investment included unearned income of $43.7 million at December 31, 2012.  We did not have an investment in direct financing leases at December 31, 2013.
	We lease office space and equipment under operating leases. We recognize rent expense related to these operating leases on a straight-line basis over the lease term. The lease term commences on the earlier of the date when we become legally obligated for the rent payments or the date on which we take possession of the property. For tenant improvement allowances and rent holidays, we record a deferred rent liability in accounts payable and accrued expenses in the consolidated statements of financial condition and amortize the deferred rent over the lease term as a reduction to occupancy and equipment rental expense in the consolidated statements of operations.
Income Taxes	'
	Income Taxes
	We compute income taxes using the asset and liability method, under which deferred income taxes are provided for the temporary differences between the financial statement carrying amounts and the tax basis of our company’s assets and liabilities. We establish a valuation allowance for deferred tax assets if it is more likely than not that these items will either expire before we are able to realize their benefits, or that future deductibility is uncertain.
	We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. We recognize interest and penalties related to uncertain tax positions in provision for income taxes/(benefit) in the consolidated statements of operations. See Note 25 for further information regarding income taxes.
Foreign Currency Translation	'
	Foreign Currency Translation
	We consolidate our foreign subsidiaries, which have designated their local currency as their functional currency. Assets and liabilities of these foreign subsidiaries are translated at year-end rates of exchange, and revenues and expenses are translated at an average rate for the period. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 830, “Foreign Currency Matters,” gains or losses resulting from translating foreign currency financial statements are reflected in accumulated other comprehensive income, a separate component of shareholders’ equity. Gains or losses resulting from foreign currency transactions are included in net income.
Recently Issued Accounting Guidance	'
	Recently Adopted Accounting Guidance
	Indefinite-Lived Assets Impairment Testing
	In July 2012, the FASB issued Update No. 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment,” which permits entities to make a qualitative assessment of whether it is more likely than not that an indefinite-lived asset is impaired. If an entity concludes that it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount, it would not be required to perform a quantitative assessment. The update also allows an entity the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment test. This guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012 (January 1, 2013 for our company) with early adoption permitted. The adoption of this new guidance did not have a material impact on our consolidated financial statements.
	Disclosures about Offsetting Assets and Liabilities
	In December 2011, the FASB issued Update No. 2011-11, “Disclosures about Offsetting Assets and Liabilities” (“Update No. 2011-11”), which enhance disclosures by requiring improved information about financial and derivative instruments that are either 1) offset (netting assets and liabilities) in accordance with Topic 210 “Balance Sheet,” and Topic 815, “Derivatives and Hedging or 2) subject to an enforceable master netting arrangement or similar agreement. This guidance is effective for interim and annual reporting periods beginning on or after January 1, 2013, and requires retrospective disclosures for comparative periods presented.
	In January 2013, the FASB issued Update No. 2013-01, “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities,” which clarifies the scope of Update No. 2011-11 to include derivatives accounted for in accordance with Topic 815, “Derivatives and Hedging”, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset or subject to an enforceable master netting arrangement or similar agreement. This guidance is effective for interim and annual reporting periods beginning on or after January 1, 2013, and requires retrospective disclosures for comparative periods presented. Other than requiring additional disclosures regarding offsetting assets and liabilities, the adoption of this new guidance did not have an impact on our consolidated financial statements. See Note 17 – Disclosures About Offsetting Assets and Liabilities.
	Comprehensive Income
	In February 2013, the FASB issued Update No. 2013-02, “Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income,” which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. This guidance is effective for interim and annual reporting periods beginning after December 15, 2012 (January 1, 2013 for our company). Other than requiring additional disclosures regarding other comprehensive income, the adoption of this new guidance did not have an impact on our consolidated financial statements.
