Accounting Policies [Abstract]
Organization and Significant Accounting Policies	NOTE 1 . ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES Organization and Business Description Bimini Capital Management, Inc., a Maryland corporation (“Bimini Capital” or the “Company” ), was formed in September 2003 for the purpose of creating and managing a leveraged investment portfolio consisting of residential mortgage-backed securities (“MBS”). In addition, the Company manages an MBS p ortfolio for Orchid Island Capital, Inc. (“Orchid”) and receives fees for providing these services. Consolidation The accompanying consolidated financial statements include the accounts of Bimini Capital, its wholly-owned subsidiaries, Bimini Advisors Holdings, LLC (formerly known as Bimini Advisors, Inc.) and Royal Palm Capital, LLC (formerly known as MortCo TRS, LLC). Bimini Advisors Holdings, LLC and its wholly-owned subsidiary, Bimini Advisors, LLC are collectively referred to as "Bimini Advisors. " Royal Palm Capital, LLC and its wholly-owned subsidiaries are collectively referred to as "Royal Palm." All inter-company accounts and transactions have been eliminated from the consolidated financial statements. Financial Accounting Standards Board ( the "FASB") Accounting Standards Codification ("ASC") Topic 810, Consolidation, requires the consolidation of a variable interest entity ("VIE") by an enterprise if it is deemed the primary beneficiary of the VIE. Bimini Capital has a common share investme nt in a trust used in connection with the issuance of Bimini Capital's junior subordinated notes. See Note 8 for a description of the accounting used for this VIE. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not incl ude all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operatin g results fo r the six and three month periods ended June 30, 2017 are not necessarily indicative of the results that may be expected for the year end ing December 31, 2017 . The consolidated balance sheet at December 31, 2016 has been derived from the aud ited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete consolidated financial statements. For further information, refer to the financial statements and footnotes thereto included in the Company’s A nnual R eport on Form 10-K for the year ended December 31, 2016 . Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of a ssets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates affecting the accompanying consolidated financial statements include the fair values of MBS, investment in Orchid common shares, derivatives, retained interests, asset valuation allowances and deferred tax asset allowances recorded for each accou nting period. Statement of Comprehensive Income In accordance with ASC Topic 220, Comprehensive Income , a statement of comprehensive income has not been included as the Company has no items of other comprehensive income (loss) . Comprehensive income is the same as net income for all periods presented. Cash and Cash Equivalents and Restricted Cash Cash and cash equivalents include cash on deposit with financial institutions and highly liquid investments with original maturities of three months or less at the time of purchase. Restricted cash includes cash pledged as collateral for repurchase agreements and derivative instruments. (in thousands) June 30, 2017 December 31, 2016 Cash and cash equivalents $ 6,398,651 $ 4,429,459 Restricted cash 588,620 1,221,978 Total cash, cash equivalents and restricted cash $ 6,987,271 $ 5,651,437 The Company maintains cash balances at several banks, and at times, these balances may exceed federally insured limits. The Company has not experienced any losses related to these balances. The Federal Deposit Insurance Corporation insures eligible accounts up to $250,000 per depositor at each financial institution. At June 30, 2017 , the Company’s cash deposits exceeded federally insured limits by approximately $4.6 million. Restricted cash balances are uninsured, but are held in sep arate customer accounts that are segregated from the general funds of the counterparty. The Company limits uninsured balances to only large, well-known bank s and derivative counterparties and believes that it is not exposed to significant credit risk on c ash and cash equivalents or restricted cash balances. Mortgage-Backed Securities The Company invests primarily in mortgage pass-through (“PT”) certificates, collateralized mor tgage obligations, and interest- only (“IO”) securities and inverse interest- onl y (“IIO”) securities representing interest in or obligations backed by pools of mortgage-backed loans. The Company has elected to account for its investment in MBS under the fair value option. Electing the fair value option requires the Company to record changes in fair value in the consolidated statement of operations, which, in management’s view, more appropriately reflects the results of our operations for a particular reporting period and is consistent with the underlying economi cs and how the portfolio is managed. The Company records MBS transactions on the trade date. Security purchases that have not settled as of the balance sheet date are included in the MBS balance with an offsetting liability recorded, whereas securit ies s old that have not settled as of the balance sheet date are removed from the MBS balance with an offsetting receivable recorded. The fair value of the Company’s investment in MBS is governed by ASC Topic 820, Fair Value Measurement . The definition of fair value in ASC Topic 820 focuses on the price that would be received to sell the asset or paid to transfer the liability in an orderly transaction between market participants at the measurement date. The fair value measurement assumes that the transaction to sell the asset or transfer the liability either occurs in the principal market for the asset or liability, or in the absence of a principal market, occurs in the most advantageous market for the asset or liability. Estimated fair values for MBS are base d on independent pricing sources and/or third-party broker quotes, when available. Income on PT MBS is based on the stated interest rate of the security. Premiums or discounts present at the date of purchase are not amortized. Premium lost and discount accretion resulting from monthly principal repayments are reflected in unrealize d gains on MBS in the c ons olidated statements of operations. For IO securities, the income is accrued based on the carrying value and the effective yield. The difference betwe en income accrued and the interest received on the security is characterized as a return of investment and serves to reduce the asset’s carrying value. At each reporting date, the effective yield is adjusted prospectively from the reporting period based on the new estimate of prepayments and the contractual terms of the security. For IIO securities, effective yield and income recognition calculations also take into account the index value applicable to the security. Changes in fair value of MBS during eac h reporting period are recorded in earnings and reported as unrealized gains or losses on mortgage-backed securities in the accompanying consolidated statements of operations. The amount reported as unrealized gains or losses on mortgage backed securities thus captures the net effect of changes in the fair market value of securities caused by market developments and any premium or discount lost as a result of principal repayments during the period. Orchid Island Capital, Inc. Common Stock The Company has elected the fair value option for its investment in Orchid common shares. The change in the fair value of this investment and dividends received on this investment are reflected in other income in the consolidated statements of operations. We estimate th e fair value of our investment in Orchid on a market approach using “Level 1” inputs based on the quoted market price of Orchid’s common stock on a national stock exchange. Electing the fair value option requires the Company to record changes in fair value in the consolidated statement s of operations, which, in management’s view, mo re appropriately reflects the results of our operations for a particular reporting period and is consistent with how the investment is managed. Advisory Services Orchid is externally managed and advised by Bimini Advisors pursuant to the terms of a management agreement. Under the terms of the management agreement , Orchid is obligated to pay Bimini Advisors a monthly management fee and a pro rata portion of certain overhead costs and to reimburse the Company for any direct expenses incurred on its behalf. Retained Interests in Securitizations Retained interests in the subordinated tranches of securities created in securitization transactions were initially recorded at their fair value when issued by Royal Palm. Subsequent adjustments to fair value are reflected in earnings. Quoted market prices for these assets are generally not available, so the Company estimates fair value based on the present value of expected future cash flows using management’s best estimates of key assumptions, which include expected credit losses, prepayment speeds, weighted-average life, and discount rates commensurate with the inherent risks of the asset. Derivative Financial Instruments The Company uses derivative instruments to manage interest rate risk, facilitate asset/liability strategies and manage other exposures, and it may continue to do so in the future. The principal instruments that the Company has used to date are Treasury Note (“ T-Note”) and Eurodollar futures contracts, but the Company may enter into other transactions in the future. The Company has elected not to treat any of its derivative financial instruments as hedges in order to align the accounting treatment of its deri vative instruments with the treatment of its portfolio assets under the fair value option. FASB ASC Topic 815, Derivatives and Hedging , requires that all derivative instruments be carried at fair value. Changes in fair value are recorded in earnings for each period. Holding derivatives creates exposure to credit risk related to the potential for failure on the part of counterparties to honor their commitments. In addition, the Company may be required to post collateral based on any declines in the marke t value of the derivatives. In the event of default by a counterparty, the Company may have difficulty recovering its collateral and may not receive payments provided for under the terms of the agreement. To mitigate this risk, the Company uses only well -established commercial banks as counterparties. Financial Instruments ASC Topic 825 , Financial Instruments , requires disclosure of the fair value of financial instruments for which it is practicable to estimate that value, either in the body of the financial statements or in the accompanying notes. MBS, Orchid common stock, Eurodollar futures contracts, interest rate swaptions and retained interests in securitization transactions are accounted for at fair value in the consolidated balance sheets. The methods and assumptions used to estimate fair value for these instruments are presented in Note 14 of the consolidated financial statements. The estimated fair value of cash and cash equivalents, restricted cash, accrued interest receivable, other asse ts, repurchase agreements, accrued interest payable and other liabilities generally approximates their carrying value as of June 30, 2017 and December 31, 2016 , due to the short-term nature of these financial in struments. It is impractical to estimate the fair value of the Company’s junior subordinated notes. Currently, there is a limited market for these types of instruments and the Company is unable to ascertain what interest rates would be available to the Company for similar financial instruments. Information regarding carrying amount and effective interest rate for these instruments is presented in Note 8 to the consolidated financial statements. Property and Equipment, net Property and equipment, net, consists of computer equipment with a depreciable life of 3 years, office furniture and equipment with depreciable lives of 8 to 20 years, land which has no depreciable life, and buildings and improvements with depreciable lives of 30 years. Property and equipment is recorded at acquisition cost and depreciated using the straight-line method over the estimated useful lives of the assets. Repurchase Agreements The Company finances the acquisition of the majority of its PT MBS through the use of repur chase agreements under master repurchase agreements. Pursuant to ASC Topic 860, Transfers and Servicing , the Company account s for repurchase transactions as collateralized financing transactions, which are carried at their contractual amounts, including accrued interest, as specified in the respective agreements . Share-Based Compensation The Com pany follows the provisions of ASC Topic 718, Compensation – Stock Compensation , to account for stock and stock-based awards. For stock and stock-based awards issued to employees, a compensation charge is recorded against earnings over the vesting period based on the fair value of the award. The Company applies a zero forfeiture rate for its equity based awards, as such awards have been granted to a limited number of employees and historical forfeitures have been minimal. A significant forfeiture, or an indication that significant forfeitures may occur, would result in a revised forfeiture rate which would be accounted for prospectively as a change in an estimate. For transactions with non-employees in which services are performed in exchange for the Comp any’s common stock or other equity instruments, the transactions are recorded on the basis of the fair value of the service received or the fair value of the equity instruments issued, whichever is more readily measurable at the date of issuance. Earnings Per Share The Company follows the provisions of ASC Topic 260, Earnings Per Share , which requires companies with complex capital structures, common stock equivalents or two (or more) classes of securities that participate in dividend distributions to present both basic and diluted earnings per share (“EPS”) on the face of the consolidated statement of operations. Basic EPS is calculated as income available to common stockholders divided by the weighted average number of common shares outstanding du ring the period. Diluted EPS is calculated using the treasury stock or two-class method, as applicable for common stock equivalents. However, the common stock equivalents are not included in computing diluted EPS if the result is anti-dilutive. Outstandin g shares of Class B Common Stock, participating and convertible into Class A Common Stock, are entitled to receive dividends in an amount equal to the dividends declared on each share of Class A Common Stock if, as and when authorized and declared by the B oard of Directors. Accordingly, shares of the Class B Common Stock are included in the computation of basic EPS using the two-class method and, consequently, are presented separately from Class A Common Stock. The shares of Class C Common Stock are not in cluded in the basic EPS computation as these shares do not have participation rights. The outstanding shares of Class B and Class C Common Stock are not included in the computation of diluted EPS for the Class A Common Stock as the conditions for conversio n into shares of Class A Common Stock were not met. Income Taxes For the calendar year ended December 31, 2015, Bimini Capital, Bimini Advisors, Inc. and Royal Palm were separate taxpaying entities for income tax purposes and filed separate Federal income tax returns. Bimini Advisors, Inc. remained a separate tax paying entity through January 31, 2016; on that date, Bimini Advisors, Inc. was reorganized (as Bimini Advisors Holdings, LLC) to be an LLC wholly-owned by Bimini Capital. Beginning with the tax period starting on February 1, 2016, Bimini Capital and Bimini Advisors are combined as a single tax paying entity. Royal Palm continues to be treated as a separate tax paying entity. Income taxes are provided for using the asset and liability method. Deferred tax assets and liabilities represent the differences between the financial statement and income tax bases of assets and liabilities using enacted tax rates. The measurement of net deferred tax assets is adjusted by a valuation allowance if, based on the Company’s evaluation, it is more likely than not that they will not be realized. The Company’s U.S. federal income tax returns for years ended on or after December 31, 2013 rema in open for examination. Although management believes its calculations for tax returns are correct and the positions taken thereon are reasonable, the final outcome of tax audits could be materially different from the tax returns filed by the Company, and those differences could result in significant costs or benefits to the Company. The Company measures, recognizes and presents its uncertain tax positions in accordance with ASC Topic 740, Income Taxes . Under that guidance, the Company assesses the likeli hood, based on their technical merit, that tax positions will be sustained upon examination based on the facts, circumstances and information available at the end of each period. The measurement of uncertain tax positions is adjusted when new information is available, or when an event occurs that requires a change. The Company recognizes tax positions in the financial statements only when it is more likely than not that the position will be sustained upon examination by the relevant taxing authority based on the technical merits of the position. A position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized upon settlement. The difference between the benefit recognized and the tax benefit claimed on a tax return is referred to as an unrecognized tax benefit and is recorded as a liability in the consolidated balance sheets. The Company records income tax-related interest and penalties, if applicable, within the income tax provision.

Derivative Financial Instruments [Abstract]
Derivative Financial Instruments	NOTE 5 . DERIVATIVE FINANCIAL INSTRUMENTS In connection with its interest rate risk management strategy, the Company economically hedges a portion of the cost of its repurchase agreement funding and junior subordinated notes by entering into derivative s and other hedging contracts. To date the Company has entered into Eurodollar and T-Note futures contracts, but may enter into other contracts in the future . The Company has not elected hedging treatment under GAAP, and as s uch all gains or losses (realized and unrealized) on these instruments are reflected in earnings for all periods presented. As of June 30, 2017 and December 31, 2016 , such instruments were comprised entirely of Eurodollar futures contracts . Eurodollar f utures are cash settled futures contracts on an interest rate, with gains or losses credited or charged to the Company’s account on a daily basis and reflected in earnings as they occur. A minimum balance, or “margin”, is required to be maintained in the a ccount on a daily basis. The Company is exposed to the changes in value of the futures by the amount of margin held by the broker. This margin represents the collateral the Company has posted for its open positions and is recorded on the consolidated bala nce sheets as part of restricted cash.

The Company attempts to minimize this risk in several ways. For instruments which are not centrally cleared on a registered exchange , the Company limits its counterparties to major financial institutions with acceptable credit ratings , and by m onitoring positions with individual counterparties. In addition, the Company may be required to pledge assets as collateral for its derivatives, whose amounts vary over time based on the market value, notional amount and remaining term of the derivative co ntract. In the event of a default by a counterparty, the Company may not receive payments provided for under the terms of its derivative agreements, and may have difficulty obtaining its assets pledged as collateral for its derivatives. The cash and cash e quivalents pledged as collateral for the Company’s derivative instruments are included in restricted cash on the consolidated balance sheets.

Trust Preferred Securities [Abstract]
Trust Preferred Securities	NOTE 8 . TRUST PREFERRED SECURITIES During 2005, Bimini Capital sponsored the formation of a statutory trust, known as Bimini Capital Trust II (“BCTII”) of which 100% of the common eq uity is owned by Bimini Capital. It was formed for the purpose of issuing trust preferred capital securities to third-party investors and investing the proceeds from the sale of such capital securities solely in junior subordinated debt securities of Bimini Capital. The debt securities held by BCTII are the sole assets of BCTII . As of June 30, 2017 and December 31, 2016 , the outstanding principal balance on the junior subordinated debt securities owed to BCTII was $26.8 million. The BCTII trust preferred securities and Bimini Capital's BCTII Junior Subordinated Notes have a rate of interest that floats at a spread of 3.50% over the prevailing three-month LIBOR rate. As of June 30, 2017 , the interest rate was 4.75% . The BCTII trust preferred securities and Bimini Capital's BCTII Junior Subordinated Notes require quarterly interest distributions and are redeemable at Bimini Capital's option, in whole or in part and without penalty. Bimini Capital's BCTII Junior Subordinated Notes are subordinate and junior in right of payment of all prese nt and future senior indebtedness. BCTII is a VIE because the holders of the equity investment at risk do not have adequate decision making ability over BCTII’s activities. Since Bimini Capital's investment in BCTII’s common equity securities was finance d directly by BCTII as a result of its loan of the proceeds to Bimini Capital, that investment is not considered to be an equity investment at risk. Since Bimini Capital's common share investment in BCTII is not a variable interest, Bimini Capital is not t he primary beneficiary of BCTII. Therefore, Bimini Capital has not consolidated the financial statements of BCTII into its consolidated financial statements, and this investment is accounted for on the equity method . The accompanying consolidated financial statements present Bimini Capital's BCTII Junior Subordin ated Notes issued to BCTII as a liability and Bimini Capital's investment in the common equity securities of BCTII as an asset (included in other assets). For financial statement purposes, Bimini Capital records payments of interest on the Junior Subordin ated Notes issued to BCTII as interest expense.

Stock incentive Plans	NOTE 10 . STOCK INCENTIVE PLANS On August 12, 2011, Bimini Capital’s shareholders approved the 2011 Long Term Compensation Plan (the “2011 Plan”) to assist the Company in recruiting and retaining employees, directors and other service providers by enabling them to participate in the success of Bimini Capital and to associate their interest s with those of the Company and its stockholders. The 2011 Plan is intended to permit the grant of stock options, stock appreciation rights (“SARs”), stock awards , performance units and other equity-based and incentive awards. The maximum aggregate number of shares of common stock that may be issued under the 2011 Plan pursuant to the exercise of options and SARs, the grant of stock awards or other equity-based aw ards and the settlement of incentive awards and performance units is equal to 4,000,000 shares. Share Awards During the three months ended March 31, 2016 , the Compensation Committee of the Board of Directors of Bimini Capital (the “Committee”) approved certain performance bonuses for members of management. These bonuses were awarded primarily in recognition of service in 2015. The bonuses consisted of cash of approximately $0.5 million and 258,333 fully vested shares of the Company’s Class A Common Sto ck with an approximate value of $0.2 million, or $0.75 per share. The shares were issued under the 2011 Plan. For purposes of these bonuses, shares of the Company’s common stock were valued based on the closing price of the Company’s Class A Common Stock on January 15, 2016, the bonus date. The expense related to this bonus was accrued at December 31, 2015 and does not affect the results of operations for the six and three months ended June 30, 2016 . Performance Units The Committee may issue Performance Units under the 2011 Plan to certain officers and employees. “Performance Units” represent the participant’s right to receive an amount, based on the value of a specified number of shares of common stock, if the terms and conditions prescribed by the Committee are satisfied. The Committee will determine the requirements that must be satisfied before Performance Units are earned, including but not limited to any applicable performance period and performance goals. Performance goals may relate to the Company’s financial performance or the participant’s performance or such other criteria determined by the Committee, including goals stated with reference to the performance measures discussed below. If Performance Units are earned, they will be settled in cash, shares of common stock or a combination thereof.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 12 . INCOME TAXES The total income tax provision recorded for the six months ended June 30, 2017 and 2016 was $ 0.3 million and $0.7 million, respectively, on consolidated pre-tax book income of $ 0.7 million and $ 1.7 million in the six months ended June 30, 2017 and 2016 , respectively. The total income tax provision recorded for the three months ended June 30, 2017 and 2016 was $ 0.4 million and $0.4 million, respectively, on consolidated pre-tax book income of $ 1.1 million and $ 1.0 million in the three months ended June 30, 2017 and 2016 , respectively. The Company ’s tax provision is based on a projected effective rate based annualized amounts and includes the expected realiz ation of a portion of the tax benefits of feder al and state net operating losses carryforwards (“NOLs”) . In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of capital loss and NOL carryforwards is dependent upon the generation of future capital gains and taxable income in periods prior to their expiration. The Company currently provides a valuation allowance against a portion of the NOLs since the Company believes that it is more likely than not that some of the benefits will not be realized in the future. The Company will continue to assess the need for a valuation allowance at each reporting date.

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 13 . EARNINGS PER SHARE Shares of Class B common stock , participating and convertible into Class A common stock , are entitled to receive dividends in an amount equal to the dividends declared on each share of Class A common stock if, and when, authorized and declared by the Board of Directors. Following the provisions of FASB ASC 260, the Class B common stock is included in the computation of basic EPS using the two-class method, and consequently is presented separately from Class A common stock . Shares of Class B common stock are not included in the computation of diluted Class A EPS as the conditions for conversion to Class A common stock were not met at June 30, 2017 and 2016 . Shares of Class C common stock are not included in the basic EPS computation as these shares do not have participation rights. Shares of Class C common stock are not included in the computation of diluted Class A EPS as the conditions for conversion to Class A common stock were not met at June 30, 2017 and 2016 . The Company has dividend eligible stock incentive plan shares that were outstanding during the six and three months ended June 30, 2017 . The basic and diluted per share computations include these unvested incentive plan shares if there is income available to Class A common stock , as they have dividend participation rights. The stock incentive plan shares have no contractual obligation to share in losses. Because there is no such obligation, the incentive plan shares are not includ ed in the basic and diluted EPS computations when no income is available to Class A common stock even though they are considered participating securities.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	NOTE 14 . FAIR VALUE Authoritative accounting literature establishes a framework for using fair value to measure assets and liabilities and defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) as opposed to the price that would be paid to acquire the asset or received to assume the liability (an entry price). A fair value measure should reflect the assumptions that market participants would use in pricing the asset or liability, incl uding the assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset and the risk of non-performance. Required disclosures include stratification of balance sheet amounts measured at fair value based on inputs the Company uses to derive fair value measurements. These stratifications are: Level 1 valuations, where the valuation is based on quoted market prices for identical assets or liabilities traded in active markets (which include exchanges and over-the-counter markets with sufficient volume), Level 2 valuations, where the valuation is based on quoted market prices for similar instruments traded in active markets, quoted prices for identical or similar instruments in markets that ar e not active and model-based valuation techniques for which all significant assumptions are observable in the market, and Level 3 valuations, where the valuation is generated from model-based techniques that use significant assumptions not observable in th e market, but observable based on Company-specific data. These unobservable assumptions reflect the Company’s own estimates for assumptions that market participants would use in pricing the asset or liability. Valuation techniques typically include option pricing models, discounted cash flow models and similar techniques, but may also include the use of market prices of assets or liabilities that are not directly comparable to the subject asset or liability. The Company’s MBS are valued using Level 2 valua tions, and such valuations currently are determined by the Company based on independent pricing sources and/or third-party broker quotes, when available. Because the price estimates may vary, the Company must make certain judgments and assumptions about th e appropriate price to use to calculate the fair values. Alternatively, the Company could opt to have the value of all of its MBS positions determined by either an independent third-party or could do so internally. MBS, Orchid common stock, retained interests and futures contracts were all recorded at fair value on a recurring basis during the six and three months ended June 30, 2017 and 2016 . When determining fair value measurements, the Company considers the principal or most advantageous market in which it w ould transact and considers assumptions that market participants would use when pricing the asset. When possible, the Company looks to active and observable markets to price identical assets. When identical assets are not traded in active markets, the Com pany looks to market observable data for similar assets. Fair value measurements for the retained interests are generated by a model that requires management to make a significant number of assumptions. The following table presents financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2017 and December 31, 2016 : (in thousands) Quoted Prices in Active Significant Markets for Other Significant Identical Observable Unobservable Fair Value Assets Inputs Inputs Measurements (Level 1) (Level 2) (Level 3) June 30, 2017 Mortgage-backed securities $ 142,483 $ - $ 142,483 $ - Margin posted on derivative agreements 574 574 - - Orchid Island Capital, Inc. common stock 14,988 14,988 - - Retained interests 644 - - 644 December 31, 2016 Mortgage-backed securities $ 130,302 $ - $ 130,302 $ - Margin posted on derivative agreements 766 766 - - Orchid Island Capital, Inc. common stock 15,108 15,108 - - Retained interests 1,114 - - 1,114 The following table illustrates a roll forward for all assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the six months ended June 30, 2017 and 2016 : (in thousands) Retained Interests Six Months Ended June 30, 2017 2016 Balances, January 1 $ 1,114 $ 1,124 Gain included in earnings 304 1,080 Collections (774) (845) Balances, June 30 $ 644 $ 1,359 During the six months ended June 30, 2017 and 2016 , there were no transfers of financial assets or liabilities between levels 1, 2 or 3. Our retained interests are valued based on a discounted cash flow approach. These values are sensitive to changes in unobservable inputs, including: estimated prepayment speeds, default rates and loss severity, weighted-average life, and discount rates. Significant increases or decreases in any of these inputs may result in significantly different fair value measurements.

Accounting Policies [Abstract]
Consolidation	Consolidation The accompanying consolidated financial statements include the accounts of Bimini Capital, its wholly-owned subsidiaries, Bimini Advisors Holdings, LLC (formerly known as Bimini Advisors, Inc.) and Royal Palm Capital, LLC (formerly known as MortCo TRS, LLC). Bimini Advisors Holdings, LLC and its wholly-owned subsidiary, Bimini Advisors, LLC are collectively referred to as "Bimini Advisors. " Royal Palm Capital, LLC and its wholly-owned subsidiaries are collectively referred to as "Royal Palm." All inter-company accounts and transactions have been eliminated from the consolidated financial statements. Financial Accounting Standards Board ( the "FASB") Accounting Standards Codification ("ASC") Topic 810, Consolidation, requires the consolidation of a variable interest entity ("VIE") by an enterprise if it is deemed the primary beneficiary of the VIE. Bimini Capital has a common share investme nt in a trust used in connection with the issuance of Bimini Capital's junior subordinated notes. See Note 8 for a description of the accounting used for this VIE.
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not incl ude all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operatin g results fo r the six and three month periods ended June 30, 2017 are not necessarily indicative of the results that may be expected for the year end ing December 31, 2017 . The consolidated balance sheet at December 31, 2016 has been derived from the aud ited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete consolidated financial statements. For further information, refer to the financial statements and footnotes thereto included in the Company’s A nnual R eport on Form 10-K for the year ended December 31, 2016 .
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of a ssets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates affecting the accompanying consolidated financial statements include the fair values of MBS, investment in Orchid common shares, derivatives, retained interests, asset valuation allowances and deferred tax asset allowances recorded for each accou nting period.
Statement of Comprehensive Income	Statement of Comprehensive Income In accordance with ASC Topic 220, Comprehensive Income , a statement of comprehensive income has not been included as the Company has no items of other comprehensive income (loss) . Comprehensive income is the same as net income for all periods presented.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash Cash and cash equivalents include cash on deposit with financial institutions and highly liquid investments with original maturities of three months or less at the time of purchase. Restricted cash includes cash pledged as collateral for repurchase agreements and derivative instruments. (in thousands) June 30, 2017 December 31, 2016 Cash and cash equivalents $ 6,398,651 $ 4,429,459 Restricted cash 588,620 1,221,978 Total cash, cash equivalents and restricted cash $ 6,987,271 $ 5,651,437 The Company maintains cash balances at several banks, and at times, these balances may exceed federally insured limits. The Company has not experienced any losses related to these balances. The Federal Deposit Insurance Corporation insures eligible accounts up to $250,000 per depositor at each financial institution. At June 30, 2017 , the Company’s cash deposits exceeded federally insured limits by approximately $4.6 million. Restricted cash balances are uninsured, but are held in sep arate customer accounts that are segregated from the general funds of the counterparty. The Company limits uninsured balances to only large, well-known bank s and derivative counterparties and believes that it is not exposed to significant credit risk on c ash and cash equivalents or restricted cash balances.
Mortgage-Backed Securities	Mortgage-Backed Securities The Company invests primarily in mortgage pass-through (“PT”) certificates, collateralized mor tgage obligations, and interest- only (“IO”) securities and inverse interest- onl y (“IIO”) securities representing interest in or obligations backed by pools of mortgage-backed loans. The Company has elected to account for its investment in MBS under the fair value option. Electing the fair value option requires the Company to record changes in fair value in the consolidated statement of operations, which, in management’s view, more appropriately reflects the results of our operations for a particular reporting period and is consistent with the underlying economi cs and how the portfolio is managed. The Company records MBS transactions on the trade date. Security purchases that have not settled as of the balance sheet date are included in the MBS balance with an offsetting liability recorded, whereas securit ies s old that have not settled as of the balance sheet date are removed from the MBS balance with an offsetting receivable recorded. The fair value of the Company’s investment in MBS is governed by ASC Topic 820, Fair Value Measurement . The definition of fair value in ASC Topic 820 focuses on the price that would be received to sell the asset or paid to transfer the liability in an orderly transaction between market participants at the measurement date. The fair value measurement assumes that the transaction to sell the asset or transfer the liability either occurs in the principal market for the asset or liability, or in the absence of a principal market, occurs in the most advantageous market for the asset or liability. Estimated fair values for MBS are base d on independent pricing sources and/or third-party broker quotes, when available. Income on PT MBS is based on the stated interest rate of the security. Premiums or discounts present at the date of purchase are not amortized. Premium lost and discount accretion resulting from monthly principal repayments are reflected in unrealize d gains on MBS in the c ons olidated statements of operations. For IO securities, the income is accrued based on the carrying value and the effective yield. The difference betwe en income accrued and the interest received on the security is characterized as a return of investment and serves to reduce the asset’s carrying value. At each reporting date, the effective yield is adjusted prospectively from the reporting period based on the new estimate of prepayments and the contractual terms of the security. For IIO securities, effective yield and income recognition calculations also take into account the index value applicable to the security. Changes in fair value of MBS during eac h reporting period are recorded in earnings and reported as unrealized gains or losses on mortgage-backed securities in the accompanying consolidated statements of operations. The amount reported as unrealized gains or losses on mortgage backed securities thus captures the net effect of changes in the fair market value of securities caused by market developments and any premium or discount lost as a result of principal repayments during the period.
Investment In Orchid [Policy Text Block]	Orchid Island Capital, Inc. Common Stock The Company has elected the fair value option for its investment in Orchid common shares. The change in the fair value of this investment and dividends received on this investment are reflected in other income in the consolidated statements of operations. We estimate th e fair value of our investment in Orchid on a market approach using “Level 1” inputs based on the quoted market price of Orchid’s common stock on a national stock exchange. Electing the fair value option requires the Company to record changes in fair value in the consolidated statement s of operations, which, in management’s view, mo re appropriately reflects the results of our operations for a particular reporting period and is consistent with how the investment is managed.
Advisory Services [Policy Tex Block]	Advisory Services Orchid is externally managed and advised by Bimini Advisors pursuant to the terms of a management agreement. Under the terms of the management agreement , Orchid is obligated to pay Bimini Advisors a monthly management fee and a pro rata portion of certain overhead costs and to reimburse the Company for any direct expenses incurred on its behalf.
Retained Interests	Retained Interests in Securitizations Retained interests in the subordinated tranches of securities created in securitization transactions were initially recorded at their fair value when issued by Royal Palm. Subsequent adjustments to fair value are reflected in earnings. Quoted market prices for these assets are generally not available, so the Company estimates fair value based on the present value of expected future cash flows using management’s best estimates of key assumptions, which include expected credit losses, prepayment speeds, weighted-average life, and discount rates commensurate with the inherent risks of the asset.
Derivative Financial Instruments	Derivative Financial Instruments The Company uses derivative instruments to manage interest rate risk, facilitate asset/liability strategies and manage other exposures, and it may continue to do so in the future. The principal instruments that the Company has used to date are Treasury Note (“ T-Note”) and Eurodollar futures contracts, but the Company may enter into other transactions in the future. The Company has elected not to treat any of its derivative financial instruments as hedges in order to align the accounting treatment of its deri vative instruments with the treatment of its portfolio assets under the fair value option. FASB ASC Topic 815, Derivatives and Hedging , requires that all derivative instruments be carried at fair value. Changes in fair value are recorded in earnings for each period. Holding derivatives creates exposure to credit risk related to the potential for failure on the part of counterparties to honor their commitments. In addition, the Company may be required to post collateral based on any declines in the marke t value of the derivatives. In the event of default by a counterparty, the Company may have difficulty recovering its collateral and may not receive payments provided for under the terms of the agreement. To mitigate this risk, the Company uses only well -established commercial banks as counterparties.
Financial Instruments	Financial Instruments ASC Topic 825 , Financial Instruments , requires disclosure of the fair value of financial instruments for which it is practicable to estimate that value, either in the body of the financial statements or in the accompanying notes. MBS, Orchid common stock, Eurodollar futures contracts, interest rate swaptions and retained interests in securitization transactions are accounted for at fair value in the consolidated balance sheets. The methods and assumptions used to estimate fair value for these instruments are presented in Note 14 of the consolidated financial statements. The estimated fair value of cash and cash equivalents, restricted cash, accrued interest receivable, other asse ts, repurchase agreements, accrued interest payable and other liabilities generally approximates their carrying value as of June 30, 2017 and December 31, 2016 , due to the short-term nature of these financial in struments. It is impractical to estimate the fair value of the Company’s junior subordinated notes. Currently, there is a limited market for these types of instruments and the Company is unable to ascertain what interest rates would be available to the Company for similar financial instruments. Information regarding carrying amount and effective interest rate for these instruments is presented in Note 8 to the consolidated financial statements.
Property and Equipment, net	Property and Equipment, net Property and equipment, net, consists of computer equipment with a depreciable life of 3 years, office furniture and equipment with depreciable lives of 8 to 20 years, land which has no depreciable life, and buildings and improvements with depreciable lives of 30 years. Property and equipment is recorded at acquisition cost and depreciated using the straight-line method over the estimated useful lives of the assets.
Repurchase Agreements	Repurchase Agreements The Company finances the acquisition of the majority of its PT MBS through the use of repur chase agreements under master repurchase agreements. Pursuant to ASC Topic 860, Transfers and Servicing , the Company account s for repurchase transactions as collateralized financing transactions, which are carried at their contractual amounts, including accrued interest, as specified in the respective agreements .
Share-Based Compensation	Share-Based Compensation The Com pany follows the provisions of ASC Topic 718, Compensation – Stock Compensation , to account for stock and stock-based awards. For stock and stock-based awards issued to employees, a compensation charge is recorded against earnings over the vesting period based on the fair value of the award. The Company applies a zero forfeiture rate for its equity based awards, as such awards have been granted to a limited number of employees and historical forfeitures have been minimal. A significant forfeiture, or an indication that significant forfeitures may occur, would result in a revised forfeiture rate which would be accounted for prospectively as a change in an estimate. For transactions with non-employees in which services are performed in exchange for the Comp any’s common stock or other equity instruments, the transactions are recorded on the basis of the fair value of the service received or the fair value of the equity instruments issued, whichever is more readily measurable at the date of issuance.
Earnings Per Share	Earnings Per Share The Company follows the provisions of ASC Topic 260, Earnings Per Share , which requires companies with complex capital structures, common stock equivalents or two (or more) classes of securities that participate in dividend distributions to present both basic and diluted earnings per share (“EPS”) on the face of the consolidated statement of operations. Basic EPS is calculated as income available to common stockholders divided by the weighted average number of common shares outstanding du ring the period. Diluted EPS is calculated using the treasury stock or two-class method, as applicable for common stock equivalents. However, the common stock equivalents are not included in computing diluted EPS if the result is anti-dilutive. Outstandin g shares of Class B Common Stock, participating and convertible into Class A Common Stock, are entitled to receive dividends in an amount equal to the dividends declared on each share of Class A Common Stock if, as and when authorized and declared by the B oard of Directors. Accordingly, shares of the Class B Common Stock are included in the computation of basic EPS using the two-class method and, consequently, are presented separately from Class A Common Stock. The shares of Class C Common Stock are not in cluded in the basic EPS computation as these shares do not have participation rights. The outstanding shares of Class B and Class C Common Stock are not included in the computation of diluted EPS for the Class A Common Stock as the conditions for conversio n into shares of Class A Common Stock were not met.
Income Taxes	Income Taxes For the calendar year ended December 31, 2015, Bimini Capital, Bimini Advisors, Inc. and Royal Palm were separate taxpaying entities for income tax purposes and filed separate Federal income tax returns. Bimini Advisors, Inc. remained a separate tax paying entity through January 31, 2016; on that date, Bimini Advisors, Inc. was reorganized (as Bimini Advisors Holdings, LLC) to be an LLC wholly-owned by Bimini Capital. Beginning with the tax period starting on February 1, 2016, Bimini Capital and Bimini Advisors are combined as a single tax paying entity. Royal Palm continues to be treated as a separate tax paying entity. Income taxes are provided for using the asset and liability method. Deferred tax assets and liabilities represent the differences between the financial statement and income tax bases of assets and liabilities using enacted tax rates. The measurement of net deferred tax assets is adjusted by a valuation allowance if, based on the Company’s evaluation, it is more likely than not that they will not be realized. The Company’s U.S. federal income tax returns for years ended on or after December 31, 2013 rema in open for examination. Although management believes its calculations for tax returns are correct and the positions taken thereon are reasonable, the final outcome of tax audits could be materially different from the tax returns filed by the Company, and those differences could result in significant costs or benefits to the Company. The Company measures, recognizes and presents its uncertain tax positions in accordance with ASC Topic 740, Income Taxes . Under that guidance, the Company assesses the likeli hood, based on their technical merit, that tax positions will be sustained upon examination based on the facts, circumstances and information available at the end of each period. The measurement of uncertain tax positions is adjusted when new information is available, or when an event occurs that requires a change. The Company recognizes tax positions in the financial statements only when it is more likely than not that the position will be sustained upon examination by the relevant taxing authority based on the technical merits of the position. A position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized upon settlement. The difference between the benefit recognized and the tax benefit claimed on a tax return is referred to as an unrecognized tax benefit and is recorded as a liability in the consolidated balance sheets. The Company records income tax-related interest and penalties, if applicable, within the income tax provision.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-18, Statement of Cash Flows – (Topic 230): Restricted Cash. ASU 2016-18 requires that restricted cash and restricted cash equivalents be included as compo nents of total cash and cash equivalents as presented on the statement of cash flows. ASU 2016-18 is effective for fiscal years, and for interim periods within those years, beginning after December 15, 2017. Early application is permitted. The Company ad opted the ASU beginning with the first quarter of 2017. The prior period consolidated statement of cash flows has been retrospectively adjusted to conform to this presentation.

ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss mod el (referred to as the current expected credit loss (CECL) model). ASU 2016-13 is effective for fiscal years, and for interim periods within those years, beginning after December 15, 2019. Early application is permitted for fiscal periods beginning after December 15, 2018. The Company is currently evaluating the potential effect of this ASU on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement o f Financial Assets and Financial Liabilities. ASU 2016-01 provides guidance for the recognition, measurement, presentation and disclosure of financial assets and financial liabilities. ASU 2016-01 is effective for fiscal years, and for interim periods wi thin those years, beginning after December 15, 2017 and, for most provisions, is effective using the cumulative-effect transition approach. Early application is permitted for certain provisions. The Company is currently evaluating the potential effect of this ASU on its consolidated financial statements.
