Accounting Policies [Abstract]
Organization and Significant Accounting Policies	Organization and Business Description Orchid Island Capital, Inc. (“Orchid” or the “Company”), was incorporated in Maryland on August 17, 2010 for the purpose of creating and managing a leveraged investment portfolio consisting of residentia l mortgage-backed securities (“RMBS ”). From incorporation t o February 20, 2013 Orchid was a wholly owned subsidia ry of Bimini Capital Management, Inc. (“Bimini”). Orchid began operations on November 24, 2010 (the date of commencement of operations). From incorporation through November 24, 2010, Orchid’s only activity was the issuance of common stock to Bimini. On February 20, 2013, Orchid completed the initial public offering (“IPO”) of its common stock in which it sold approximately 2.4 million shares of its common stock and raised gross proceeds of $35.4 million, which were invested in RMBS that were issued and t he principal and interest of which were guaranteed by a federally chartered corporation or agency (“Agency RMBS”) on a leveraged basis. Orchid is an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). On March 2, 2015, Orchid entered into an equity distribution agreement (the “March 2015 Equity Distribution Agreement”) with two sales agents pursuant to which the Company could offer and sell, from time to time, up to an aggregate amount of $100,000,000 of shares of the Company’s common stock i n transactions that were deemed to be “at the market” offerings and privately negotiated transactions. The March 2015 Equity Distribution Agreement replaced the September 2014 Equity Distribution Agreement. The Company issued a total of 7,218,766 shares under the March 2015 Equity Distribution Agreement for aggregate gross proceeds of approximately $95.4 million, and net proceeds of approximately $93.2 million, net of commissions and fees, prior to its termination in July 2016. On July 29, 2015 the Company’s Board of Directors authorized the repurchase of up to 2,000,000 shares of the Company’s common stock. The timing, manner, price and amount of any repurchases will be determined by the Company in its discretion and will be subject to economic and market conditions, stock price, applicable legal requirements and other factors. The authorization does not obligate the Company to acquire any particular amount of common stock and the program may be suspended or discontinued at the Company’s discretion without prior notice. From the inception of the share repurchase program through December 31, 2015, the Company repurchased a total of 1,216,243 shares at an aggregate cost of approximately $10.8 million, including commissions and fees. The Company did not repurchase any shares of its common stock during the years ended December 31, 2017 and 2016. On July 29, 2016 , Orchid entered into another equity distribution agreement (the “ July 2016 Equity Distribution Agreement”) with two sales agents pursuant to whi ch the Company could offer and sell, from time to time, u p to an aggregate amount of $125 ,000,000 of shares of the Company’s common stock in transactions that were deemed to be “at the market” offerings and privately negotiated transactions. The Company i ssued a total of 10,174,992 shares under the July 2016 Equity Distribution Agreement for aggregate gross proceeds of $110.0 million, and net proceeds of approximately $ 108.2 million, net of commissions and fees, prior to its termination in February 2017 . On February 23, 2017 , Orchid entered into a nother equity distribution agreement , as amended and restated on May 10, 2017 (the “ May 2017 Equity Distribution Agreement”) , with two sales agents pursuant to which the Company could offer and sell, from time to time, u p to an aggregate amount of $125 ,000,000 of shares of the Company’s common stock in transactions that are deemed to be “at the market” offerings and privately negotiated transactions. T he Company issued a total of 12,299,032 shares under the May 20 17 Equity Distribution Agreement for aggregate gross proceeds of $125.0 million, and net proceeds of approximately $ 122.9 million, net of commissions and fees , prior to its termination in August 2017. On August 2, 2017, Orchid entered into another equity distribution agreement (the “August 2017 Equity Distribution Agreement”) with two sales agents pursuant to which the Company may offer and sell, from time to time, up to an aggregate amount of $125,000,000 of shares of the Company’s common stock in transac tions that are deemed to be “at the market” offerings and privately negotiated transactions. The August 2017 Equity Distribution Agreement replaced the May 2017 Equity Distribution Agreement. Through December 31, 2017 , the Company issued a total of 7,498,954 shares under the August 2017 Equity Distribution Agreement for aggregate gross proceeds of approximately $76.0 million, and net proceeds of approximately $ 74.7 million, net of commissions and fees. Basis of Presentation, Consolidation and Use of Estimate s The accompanying consolidated financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“GAAP”). The consolidated financial statements include the account s of our wholly-owned subsidiary, Orchid Island Casualty, LLC. Significant intercompany accounts and transactions have been eliminated. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets 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 diffe r from those estimates. The significant estimates affecting the accompanying financial statements are the fair values of RMBS and derivatives. Statement of Comprehensive Income (Loss) In accordance with the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC”) Topic 220, Comprehensive Income , a statement of comprehensive income (loss) has not been included as the Company has no items of other comprehensive income (loss) . Comprehensive income (loss) is the same as net income (loss) for the 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 les s at the time of purchase . Restricted cash includes cash pledged as collateral for repurchase agreements and other borrowings, and interest rate swaps and other derivative instruments. The following table provides a reconciliation of cash, cash equivalen ts and restricted cash reported within the statement of financial position that sum to the total of the same such amounts shown in the statement of cash flows. (in thousands) 2017 2016 Cash and cash equivalents $ 214,363 $ 73,475 Restricted cash 32,349 20,950 Total cash, cash equivalents and restricted cash $ 246,712 $ 94,425 The Company maintains cash balances at four banks and excess margin at derivative exchanges , and, at times, 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 December 31, 2017 , the Company’s cash deposits exceeded federally insured limits by approximately $213.3 million. Restric ted cash balances are uninsured, but are held in separate customer accounts that are segregated from the general funds of the counterparty. The Company limits uninsured balances to only large, well-known bank and derivative exchanges and believes th at it is not exposed to any significant credit risk on cash and cash equivalents or restricted cash balances. Mortgage-Backed Securities The Company invests primarily in mortgage pass-through (“PT”) certificates, collateralized mortgage obligations, and interest- only (“IO”) securities and inverse interest- only (“IIO”) securities representing interest in or obligations backed by pools of RMBS . T he Company has elected to account for its investment in RMBS under the fair value option. Electing the fair value option require s 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 par ticular reporting period and is consistent with the underlying economics and how the portfolio is managed. The Company records RMBS transactions on the trade date. Security purchases that have not settled as of the balance sheet date are included in the RMBS balance with an offsetting liability recorded, whereas securities sold that have not settled as of the balance sheet date are removed from the RMBS balance with an offsetting receivable recorded. The fair value of the Company’s investments in RMBS is governed by FASB ASC 820, Fair Value Measurement . The definition of fair value in FASB ASC 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 i n 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 RMBS are based on independent pricing sources and/or third party broker quotes, when available . Income on PT RMBS securities 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 repa yments are reflected in unrealized gains (losses) on RMBS in the consolidated statements of operations. For IO securities, the income is accrued based on the carrying value and the effective yield. The difference between income accrued and the interest rec eived 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 t he 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 RMBS during each reporting period are recorded in earn ings and reported as unrealized gains or losses on mortgage-backed securities in the accompanying consolidated statements of operations. 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 cont racts, interest rate swaps, options to enter in interest rate swaps (“interest rate swaptions”) and “to-be-announced” (“TBA”) securities transactions , but may enter into other derivatives in the future. The Company purchases a portion of its Agency RMBS through forward settling transactions, including TBA securities transactions. At times when market conditions are conducive, the Company may choose to move the settlement of these TBA securities transactions o ut to a later date by entering into an offsetting short position, which i s then net settled for cash, and simultaneously entering into a substantially similar TBA securities trade for a later settlement date. Such a set of transactions is referred to as a TBA “dollar roll” transaction. The TBA securities purchased at the late r settlement date are typically priced at a discount to securities for settlement in the current month. This difference is referred to as the “price drop.” The price drop represents compensation to the Company for foregoing net interest margin and is ref erred to as TBA “dollar roll income.” The Company accounts for TBA securities as derivative instruments if either the TBA securities do not settle in the shortest period of time possible or if the Company cannot assert that it is probable at inception of the TBA transaction, or throughout its term, that it will take physical delivery of the Agency RMBS for a long position, or make delivery of the Agency RMBS for a short position, upon settlement of the trade. The Company accounts for TBA dollar roll transa ctions as a series of derivative transactions. Gains, losses and dollar roll income associated with TBA securities transactions and dollar roll transactions are reported in gain (loss) on derivative instruments in the accompanying consolidated statements o f operations. The fair value of TBA securities is estimated based on similar methods used to value RMBS securities. The Company has elected not to treat any of its derivative financial instruments as hedges in order to align the accounting treatment of i ts derivative instruments with the treatment of its portfolio assets under the fair value option election . 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 d erivatives creates exposure to credit risk related to the potential for failure on the part of counterparties and exchanges to honor their commitments. In addition, the Company may be required to post collateral base d on any decli nes in the market value of the d erivatives. 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 ri sk, the Company uses only well-established comme rcial banks and exchanges as counterparties. Financial Instruments FASB ASC 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. RMBS, Eurodollar and T-Note futures contracts, interest rate swaps, interest rate swaptions and TBA securities are accounted for at fair value in the consolidated bal ance sheets. The methods and assumptions used to estimate fair value for these instruments are presented in Note 12 of the consolidated financial statements. The estimated fair value of cash and cash equivalents, restricted cash, accrued interest receiv able, receivable for securities sold, other assets, due to affiliates, repurchase agreements , payable for unsettled securities purchased, accrued interest payable and other liabilities generally approximates their carrying values as of December 31, 2017 and Dece mber 31, 2016 due to the short-term nature of these financial instruments. Repurchase Agreements The Company finances the acquisition of the majority of its RMBS through the use of repurchase agreements under master repurchase agreements. Pursuant to ASC Topic 860, Transfers and Servicing , the Company accounts for repurchase transactions as collateralized financing transactions, which are carried at their contract ual amounts, including accrued interest, as specified in the respective agreements. Manager Compensation The Company is externally managed by Bimini Advisors, LLC ( th e “Manager” or “Bimini Advisors”) , a Maryland limited liability company and wh olly-owned subsidiary of Bimini . The Company’s management agreement with the Manager provides for payment to the Manager of a management fee and reimbursement of certain operating expenses, which are accrued and expensed during the period for which they are earned o r incurred. Refer to Note 13 for the terms of the management agreement. Earnings Per Share The Company follows the provisions of FASB ASC 260, Earnings Per Share . Basic earnings per share (“EPS”) is calculated as net income or loss attributable to common stockholders divided by the weighted average number of shares of common stock outstanding or subscribed during the period. Diluted EPS is calculated using the treasury stock or two-class method, as applicable, for common stock equivalents, if any. However, the common stock equivalents are not included in computing diluted EPS if the result is anti-dilutive. Income Taxes Orchid has qualified and elected to be taxed as a real estate investment trust (“REIT”) u nder the Internal Revenue Code of 1986, as amended (the “Code ”). REITs are generally not subject to federal income tax on their REIT taxable income provided that they distribute to their stockholders at least 90% of their REIT taxable income on an annual basis. In addition, a REIT must meet other provisions of the Code to retain its tax status. Orchid measures, recognizes and presents its uncertain tax positions in accordance with FASB ASC 740, Income Taxes . Under that guidance, Orchid assesses the like lihood, 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. All of Orchid’s tax positions are categorized as highly certain. There is no accrual for any tax, interest or penalties related to Orchid’s tax position assessment. The measurement of uncertain tax positions is adjusted when new information is available, or when an event occurs that requires a change. Recent Accounting Pronou ncements 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 components 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 adopted 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. In August 2016, the FASB issued ASU 2016-15, Statement of Cas h Flows – (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. ASU 2016-15 is effective for fiscal years, and for in terim periods within those years, beginning after December 15, 2017. Early application is permitted. The Company does not believe the adoption of this ASU will have a material impact on its consolidated financial statements. In June 2016, the FASB issue d ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured usi ng an expected credit loss model (referred to as the current expected credit loss 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 p eriods 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): Recogn ition and Measurement of 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 within 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.

Disclosure of Repurchase Agreements [Abstract]
Repurchase Agreements and Other Borrowings	NOTE 3 . REPURCHASE AGREEMENTS AND OTHER BORROWINGS The Company pledges certain of its RMBS as collateral under repurchase agreements with financial institutions. Interest rates are generally fixed based on prevailing rates corresponding to the terms of the borrowings , and interest is generally paid at the termination of a borrowing . If the fair value of the pledged securities declines, lenders will typically require the Company to post additional collateral or pay down borrowings to re-establish agreed upon collateral requirements, referred to as "margin calls." Similarly, if the fair value of the pledged securities increases, lenders may release collateral back to the Company. As of December 31, 2017 , the Company had met all margin call requirements. As of December 31, 2017 , the Company had outstanding repurchase obligations of approximately $3,533.8 million with a net weighted average borrowing rate of 1.54% . These agreements were collateralized by RMBS with a fair value, including accrue d interest, of approximately $3,726.5 million, and cash pledged to the counterparties of approximately $25.3 million. As of December 31, 2016 , the Company had out standing repurchase obligations of approximately $2,793.7 million with a net weighted average borrowing rate of 1.00% . These agreements were collateralized by RMBS with a fair value, including accrued interest, of approximately $2,970.9 million , and cash pledged to the counterparties of approximately $10.8 million. As of December 31, 2017 and 2016 , the Company’s repurchase agreements had remaining maturities as summarized below: ($ in thousands) OVERNIGHT BETWEEN 2 BETWEEN 31 GREATER (1 DAY OR AND AND THAN LESS) 30 DAYS 90 DAYS 90 DAYS TOTAL December 31, 2017 Fair market value of securities pledged, including accrued interest receivable $ - $ 1,983,958 $ 1,266,590 $ 475,975 $ 3,726,523 Repurchase agreement liabilities associated with these securities $ - $ 1,871,833 $ 1,208,518 $ 453,435 $ 3,533,786 Net weighted average borrowing rate - 1.53% 1.53% 1.57% 1.54% December 31, 2016 Fair market value of securities pledged, including accrued interest receivable $ - $ 2,284,815 $ 686,065 $ - $ 2,970,880 Repurchase agreement liabilities associated with these securities $ - $ 2,154,766 $ 638,939 $ - $ 2,793,705 Net weighted average borrowing rate - 1.01% 0.96% - 1.00% If, during the term of a repurchase agreement, a lender files for bankruptcy, the Company might experience difficulty recovering its pledged assets , which could result in an unsecured claim against the lender for the difference between the amount loaned to the Company plus interest due to the counterparty and the fair value of the collateral pledged to such lender , including the accrued interest recei vable and cash posted by the Company as collateral. At December 31, 2017 , the Company had an aggregate amount at risk (the difference between the amount loaned to the Company, including interest payable and securities posted by the counterparty (if any) , and the fair value of securities and cash pledged (if any) , including accrued interest on such securities) with all counterparties of approximately $213.4 million .

We minimize this risk by limiting our counterparties for instruments which are not centrally cleared on a registered exchange to major financial institutions with acceptable credit ratings and monitoring positions with individual counterparties. In addition, we may be required to pledge assets as collateral for our derivatives, whose amounts vary over time based on the market value, notional amount and remaining term of the derivative contract. In the event of a default by a counterparty , we may not receive payments provided for under the terms of our derivative agreements, and may have difficulty obtaining our assets pledged as collateral for our derivatives. The cash and cash equivalents pledged as collateral for our derivative instruments are i ncluded in restricted cash on our consolidated balance sheets." id="sjs-B4">NOTE 4 . 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 by entering into derivatives and other hedging contracts. To date, the Company has entered into Eurodollar and T-Note futures contracts, interest rate swaps, and interest rate swaptions, but may enter into other contracts in the future. The Company has not elected hedging treatment under GAAP, and as such all gains or losses (realized and unrealized) on these instruments are reflected in earnings for all periods presented. In addition, the Company utilizes TBA securities as a means of investing in and financing Agency RMBS or as a means of reducing i ts exposure to Agency RMBS . The Company accounts for TBA securities as derivative instruments if either the TBA securities do not settle in the shortest period of time possible or if the Company cannot assert that it is p robable at inception and throughout the term of the TBA securities that it will take physical delivery of the Agency RMBS for a long position, or make delivery of the Agency RMBS for a short position, upon settlement of the trade.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 10 . INCOME TAXES The Company will generally not be subject to federal income tax on its REIT taxable income to the extent that it distributes its REIT taxable income to its stockholders and satisfies the ongoing REIT requirements, including meeting certain asset, income and stock ownership tests. A REIT must generally distribute at least 90% of its REIT taxable income to its stockholders, of which 85% generally must be distributed within the taxable year, in order to avoid the imposition of a n excise tax. The remaining balance may be distributed up to the end of the following taxable year, provided the REIT elects to treat such amount as a prior year distribution and meets certain other requirements. REIT taxable income (loss) is computed in accordance with the Code, which is different than the Company’s financial statement net income (loss) computed in accordance with GAAP. Book to tax differences primarily relate to the recognition of interest income on RMBS, unrealized gains and losses on R MBS, and the amortization of losses on derivative instruments that are treated as hedges for tax purposes. Generally, the Company’s dividend distributions are characterized as ordinary income or nontaxable return of capital based on the relative amounts o f its earnings and profits (taxable income, with certain prescribed adjustments) to total distributions applicable for a given tax year. In determining total distributions, consideration is given to the spillover distribution provisions of section 857(b )(9) of the Code. Under section 857(b)(9), of the Code, REIT common dividends declared in the fourth quarter of a calendar year with a record date prior to year-end and a payable date in January of the following year will be included in total distribution s in the year declared only to the extent of available earnings and profits. As a result, such fourth quarter common dividends may be pro-rated between tax years or may not be taxable until the following year. In accordance with section 857(b)(9) of the Code, the Company’s December 2017 dividend of $0.14 paid in January 2018 is subject to tax in 2018. The remaining dividend distributions declared in 2017 of $1.54, plus the dividend declared in December 2016 and paid in January 2017 of $0.14, are taxable in 2017. The 2017 dividend distribution described above exceeded 2017 earnings and profits by $0.71, representing 42% of the total 2017 distributions of $1.68. This nondividend distribution is characterized as return of capital and has been allocated on a pro rata basis to each 2017 dividend distribution. Nondividend distributions characterized as return of capital reduce the tax basis of related shares and are nontaxable to the recipient unless return of capital distributions in aggregate exceed tax bas is, in which case the excess is reportable as capital gain. The remaining 2017 common dividend distributions have been characterized as ordinary income of $0.97, or 58% of the total distributions. As of December 31, 2017, we had distributed all of our es timated REIT taxable income through fiscal year 2017. Accordingly, no income tax provision was recorded for 2017, 2016 and 2015.

The basic and diluted per share computations include these unvested shares of restricted common stock and P erformance U nits if there is income available to common stock, as they have dividend participation rights. The shares of restricted common stock and Performance Units have no contractual obligation to s hare in losses. Because there is no such obligation, the shares of restricted common stock and Performance Units are not included in the basic and diluted EPS computations when no income is available to common stock even though they are considered particip ating securities.

FAIR VALUE

FAIR VALUE	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value	NOTE 12 . 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 are 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 the 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 optio n 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 RMBS, interest rate swaptions an d TBA securities are valued using Level 2 valuations, 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 the appropriate price to use to calculate the fair values. Alternatively, the Company could opt to have the value of all of its positions in RMBS, interest rate swaptions and TBA securities determined by either an independent third-party or could do so internally. RMBS (based on the fair value option), interest rate swaps, interest rate swaptions, TBA securities and futures contracts were recorded at fair value on a recurring basis during the years ended December 31, 2017 and 2016 . When determining fair value measurements, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset. When p ossible, the Company looks to active and observable markets to price identical assets. When identical assets are not traded in active markets, the Company looks to market obse rvable data for similar assets. The following table presents financial assets ( liabilities) measured at fair value on a recurring basis as of December 31, 2017 and 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) December 31, 2017 Mortgage-backed securities $ 3,744,811 $ - $ 3,744,811 $ - Interest rate swaps 13,530 - 13,530 - Interest rate swaptions 3,405 - 3,405 - TBA securities (1,813) - (1,813) - December 31, 2016 Mortgage-backed securities $ 3,022,174 $ - $ 3,022,174 $ - Interest rate swaps 9,500 - 9,500 - TBA securities (1,117) - (1,117) - During the years ended December 31, 2017 , 2016 and 2015 , there were no transfers of financial assets or liabilities between levels 1, 2 or 3.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation, Consolidation and Use of Estimate s The accompanying consolidated financial statements have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“GAAP”). The consolidated financial statements include the account s of our wholly-owned subsidiary, Orchid Island Casualty, LLC. Significant intercompany accounts and transactions have been eliminated. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets 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 diffe r from those estimates. The significant estimates affecting the accompanying financial statements are the fair values of RMBS and derivatives.
Statement of Comprehensive Income	Statement of Comprehensive Income (Loss) In accordance with the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC”) Topic 220, Comprehensive Income , a statement of comprehensive income (loss) has not been included as the Company has no items of other comprehensive income (loss) . Comprehensive income (loss) is the same as net income (loss) for the 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 les s at the time of purchase . Restricted cash includes cash pledged as collateral for repurchase agreements and other borrowings, and interest rate swaps and other derivative instruments. The following table provides a reconciliation of cash, cash equivalen ts and restricted cash reported within the statement of financial position that sum to the total of the same such amounts shown in the statement of cash flows. (in thousands) 2017 2016 Cash and cash equivalents $ 214,363 $ 73,475 Restricted cash 32,349 20,950 Total cash, cash equivalents and restricted cash $ 246,712 $ 94,425 The Company maintains cash balances at four banks and excess margin at derivative exchanges , and, at times, 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 December 31, 2017 , the Company’s cash deposits exceeded federally insured limits by approximately $213.3 million. Restric ted cash balances are uninsured, but are held in separate customer accounts that are segregated from the general funds of the counterparty. The Company limits uninsured balances to only large, well-known bank and derivative exchanges and believes th at it is not exposed to any significant credit risk on cash and cash equivalents or restricted cash balances.
Mortgage-Backed Securities	Mortgage-Backed Securities The Company invests primarily in mortgage pass-through (“PT”) certificates, collateralized mortgage obligations, and interest- only (“IO”) securities and inverse interest- only (“IIO”) securities representing interest in or obligations backed by pools of RMBS . T he Company has elected to account for its investment in RMBS under the fair value option. Electing the fair value option require s 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 par ticular reporting period and is consistent with the underlying economics and how the portfolio is managed. The Company records RMBS transactions on the trade date. Security purchases that have not settled as of the balance sheet date are included in the RMBS balance with an offsetting liability recorded, whereas securities sold that have not settled as of the balance sheet date are removed from the RMBS balance with an offsetting receivable recorded. The fair value of the Company’s investments in RMBS is governed by FASB ASC 820, Fair Value Measurement . The definition of fair value in FASB ASC 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 i n 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 RMBS are based on independent pricing sources and/or third party broker quotes, when available . Income on PT RMBS securities 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 repa yments are reflected in unrealized gains (losses) on RMBS in the consolidated statements of operations. For IO securities, the income is accrued based on the carrying value and the effective yield. The difference between income accrued and the interest rec eived 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 t he 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 RMBS during each reporting period are recorded in earn ings and reported as unrealized gains or losses on mortgage-backed securities in the accompanying consolidated statements of operations.
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 cont racts, interest rate swaps, options to enter in interest rate swaps (“interest rate swaptions”) and “to-be-announced” (“TBA”) securities transactions , but may enter into other derivatives in the future. The Company purchases a portion of its Agency RMBS through forward settling transactions, including TBA securities transactions. At times when market conditions are conducive, the Company may choose to move the settlement of these TBA securities transactions o ut to a later date by entering into an offsetting short position, which i s then net settled for cash, and simultaneously entering into a substantially similar TBA securities trade for a later settlement date. Such a set of transactions is referred to as a TBA “dollar roll” transaction. The TBA securities purchased at the late r settlement date are typically priced at a discount to securities for settlement in the current month. This difference is referred to as the “price drop.” The price drop represents compensation to the Company for foregoing net interest margin and is ref erred to as TBA “dollar roll income.” The Company accounts for TBA securities as derivative instruments if either the TBA securities do not settle in the shortest period of time possible or if the Company cannot assert that it is probable at inception of the TBA transaction, or throughout its term, that it will take physical delivery of the Agency RMBS for a long position, or make delivery of the Agency RMBS for a short position, upon settlement of the trade. The Company accounts for TBA dollar roll transa ctions as a series of derivative transactions. Gains, losses and dollar roll income associated with TBA securities transactions and dollar roll transactions are reported in gain (loss) on derivative instruments in the accompanying consolidated statements o f operations. The fair value of TBA securities is estimated based on similar methods used to value RMBS securities. The Company has elected not to treat any of its derivative financial instruments as hedges in order to align the accounting treatment of i ts derivative instruments with the treatment of its portfolio assets under the fair value option election . 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 d erivatives creates exposure to credit risk related to the potential for failure on the part of counterparties and exchanges to honor their commitments. In addition, the Company may be required to post collateral base d on any decli nes in the market value of the d erivatives. 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 ri sk, the Company uses only well-established comme rcial banks and exchanges as counterparties.
Financial Instruments	Financial Instruments FASB ASC 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. RMBS, Eurodollar and T-Note futures contracts, interest rate swaps, interest rate swaptions and TBA securities are accounted for at fair value in the consolidated bal ance sheets. The methods and assumptions used to estimate fair value for these instruments are presented in Note 12 of the consolidated financial statements. The estimated fair value of cash and cash equivalents, restricted cash, accrued interest receiv able, receivable for securities sold, other assets, due to affiliates, repurchase agreements , payable for unsettled securities purchased, accrued interest payable and other liabilities generally approximates their carrying values as of December 31, 2017 and Dece mber 31, 2016 due to the short-term nature of these financial instruments.
Repurchase Agreements	Repurchase Agreements The Company finances the acquisition of the majority of its RMBS through the use of repurchase agreements under master repurchase agreements. Pursuant to ASC Topic 860, Transfers and Servicing , the Company accounts for repurchase transactions as collateralized financing transactions, which are carried at their contract ual amounts, including accrued interest, as specified in the respective agreements.
Management Fees	Manager Compensation The Company is externally managed by Bimini Advisors, LLC ( th e “Manager” or “Bimini Advisors”) , a Maryland limited liability company and wh olly-owned subsidiary of Bimini . The Company’s management agreement with the Manager provides for payment to the Manager of a management fee and reimbursement of certain operating expenses, which are accrued and expensed during the period for which they are earned o r incurred. Refer to Note 13 for the terms of the management agreement.
Earnings Per Share	Earnings Per Share The Company follows the provisions of FASB ASC 260, Earnings Per Share . Basic earnings per share (“EPS”) is calculated as net income or loss attributable to common stockholders divided by the weighted average number of shares of common stock outstanding or subscribed during the period. Diluted EPS is calculated using the treasury stock or two-class method, as applicable, for common stock equivalents, if any. However, the common stock equivalents are not included in computing diluted EPS if the result is anti-dilutive.
Income Taxes	Income Taxes Orchid has qualified and elected to be taxed as a real estate investment trust (“REIT”) u nder the Internal Revenue Code of 1986, as amended (the “Code ”). REITs are generally not subject to federal income tax on their REIT taxable income provided that they distribute to their stockholders at least 90% of their REIT taxable income on an annual basis. In addition, a REIT must meet other provisions of the Code to retain its tax status. Orchid measures, recognizes and presents its uncertain tax positions in accordance with FASB ASC 740, Income Taxes . Under that guidance, Orchid assesses the like lihood, 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. All of Orchid’s tax positions are categorized as highly certain. There is no accrual for any tax, interest or penalties related to Orchid’s tax position assessment. The measurement of uncertain tax positions is adjusted when new information is available, or when an event occurs that requires a change.
Recent Accounting Pronouncements	Recent Accounting Pronou ncements 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 components 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 adopted 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. In August 2016, the FASB issued ASU 2016-15, Statement of Cas h Flows – (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. ASU 2016-15 is effective for fiscal years, and for in terim periods within those years, beginning after December 15, 2017. Early application is permitted. The Company does not believe the adoption of this ASU will have a material impact on its consolidated financial statements. In June 2016, the FASB issue d ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured usi ng an expected credit loss model (referred to as the current expected credit loss 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 p eriods 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): Recogn ition and Measurement of 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 within 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.
