ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES	Mar. 31, 2021
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 residential mortgage-backed securities (“RMBS”). From incorporation to February 20, 2013, Orchid was a wholly owned subsidiary 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 January 23, 2020, Orchid entered into an equity distribution agreement (the “January 2020 Equity Distribution Agreement”) with three sales agents pursuant to which the Company could offer and sell, from time to time, up to an aggregate amount of $ 200,000,000 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 issued a total of 3,170,727 shares under the January 2020 Equity Distribution Agreement for aggregate gross proceeds of approximately $ 19.8 million, and net proceeds of approximately $ 19.4 million, net of commissions and fees, prior to its termination in August 2020. On August 4, 2020, Orchid entered into an equity distribution agreement (the “August 2020 Equity Distribution Agreement”) with four sales agents pursuant to which the Company may offer and sell, from time to time, up to an aggregate amount of $ 150,000,000 of shares of the Company’s common stock in transactions that are deemed to be “at the market” offerings and privately negotiated transactions. Through March 31, 2021, the Company issued a total of 10,156,561 shares under the August 2020 Equity Distribution Agreement for aggregate gross proceeds of approximately $ 54.1 million, and net proceeds of approximately $ 53.2 million, net of commissions and fees. On January 20, 2021, Orchid entered into an underwriting agreement (the “January 2021 Underwriting Agreement”) with J.P. Morgan Securities LLC (“J.P. Morgan”), relating to the offer and sale of 7,600,000 shares of the Company’s common stock. J.P. Morgan purchased the shares of the Company’s common stock from the Company pursuant to the January 2021 Underwriting Agreement at $ 5.20 per share. In addition, the Company granted J.P. Morgan a 30-day option to purchase up to an additional 1,140,000 shares of the Company’s common stock on the same terms and conditions, which J.P. Morgan exercised in full on January 21, 2021. The closing of the offering of 8,740,000 shares of the Company’s common stock occurred on January 25, 2021, with net proceeds to the Company of approximately $ 45.2 million, net of offering expenses. On March 2, 2021, Orchid entered into an underwriting agreement (the “March 2021 Underwriting Agreement”) with J.P. Morgan, relating to the offer and sale of 8,000,000 shares of the Company’s common stock. J.P. Morgan purchased the shares of the Company’s common stock from the Company pursuant to the March 2021 Underwriting Agreement at $ 5.45 per share. In addition, the Company granted J.P. Morgan a 30-day option to purchase up to an additional 1,200,000 shares of the Company’s common stock on the same terms and conditions, which J.P. Morgan exercised in full on March 3, 2021. The closing of the offering of 9,200,000 shares of the Company’s common stock occurred on March 5, 2021, with net proceeds to the Company of approximately $ 50.1 million, net of offering expenses. COVID-19 Impact Beginning in mid-March 2020, the global pandemic associated with the novel coronavirus (“COVID-19”) and related economic conditions began to impact our financial position and results of operations. As a result of the economic, health and market turmoil brought about by COVID-19, the Agency RMBS market experienced severe dislocations. This resulted in falling prices of our assets and increased margin calls from our repurchase agreement lenders, resulting in material adverse effects on our results of operations and to our financial condition. The Agency RMBS market largely stabilized after the Federal Reserve announced on March 23, 2020 that it would purchase Agency RMBS and U.S. Treasuries in the amounts needed to support smooth market functioning. As of March 31, 2021, we have timely satisfied all margin calls. The RMBS market continues to react to the pandemic and the various measures put in place to stabilize the market. To the extent the financial or mortgage markets do not respond favorably to any of these actions, or such actions do not function as intended, our business, results of operations and financial condition may continue to be materially adversely affected. Although the Company cannot estimate the length or gravity of the impact of the COVID-19 pandemic at this time, if the pandemic continues, it may continue to have materially adverse effects on the Company’s results of future operations, financial position, and liquidity during 2021. Basis of Presentation and Use of Estimates The accompanying unaudited 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 include 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. Operating results for the three month period ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. The balance sheet at December 31, 2020 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. 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 differ from those estimates. The significant estimates affecting the accompanying financial statements are the fair values of RMBS and derivatives. Management believes the estimates and assumptions underlying the financial statements are reasonable based on the information available as of March 31, 2021. Variable Interest Entities (“VIEs”) We obtain interests in VIEs through our investments in mortgage-backed securities. Our interests in these VIEs are passive in nature and are not expected to result in us obtaining a controlling financial interest in these VIEs in the future. As a result, we do not consolidate these VIEs and we account for our interest in these VIEs as mortgage-backed securities. See Note 2 for additional information regarding our investments in mortgage-backed securities. Our maximum exposure to loss for these VIEs is the carrying value of the mortgage-backed securities. 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 other borrowings, and interest rate swaps and other derivative instruments. The following table provides a reconciliation of cash, cash equivalents, 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) March 31, 2021 December 31, 2020 Cash and cash equivalents $ 211,436 $ 220,143 Restricted cash 117,155 79,363 Total cash, cash equivalents and restricted cash $ 328,591 $ 299,506 The Company maintains cash balances at three banks and excess margin on account with two exchange clearing members. 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. Restricted 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 banks and exchange clearing members and believes that 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”) residential mortgage backed certificates issued by Freddie Mac, Fannie Mae or Ginnie Mae (“RMBS”), collateralized mortgage obligations (“CMOs”), interest-only (“IO”) securities and inverse interest-only (“IIO”) securities representing interest in or obligations backed by pools of RMBS. We refer to RMBS and CMOs as PT RMBS. We refer to IO and IIO securities as structured RMBS. The Company has elected to account for its investment in RMBS under the fair value option. Electing the fair value option requires the Company to record changes in fair value in the 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 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. Fair value is defined as 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 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 repayments are reflected in unrealized gains (losses) on RMBS in the 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 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 for future reporting periods 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 RMBS during each reporting period are recorded in earnings and reported as unrealized gains or losses on mortgage-backed securities in the accompanying statements of operations. Derivative and Other Hedging Instruments The Company uses derivative and other hedging 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”), Fed Funds and Eurodollar futures contracts, short positions in U.S. Treasury securities, interest rate swaps, options to enter in interest rate swaps (“interest rate swaptions”) and “to-be-announced” (“TBA”) securities transactions, but the Company may enter into other derivative and other hedging instruments in the future. The Company accounts for TBA securities as derivative instruments. Gains and losses associated with TBA securities transactions are reported in gain (loss) on derivative instruments in the accompanying statements of operations. Derivative and other hedging instruments are carried at fair value, and changes in fair value are recorded in earnings for each period. The Company’s derivative financial instruments are not designated as hedge accounting relationships, but rather are used as economic hedges of its portfolio assets and liabilities. Holding derivatives creates exposure to credit risk related to the potential for failure on the part of counterparties and exchanges to honor their commitments. 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. The Company’s derivative agreements require it to post or receive collateral to mitigate such risk. In addition, the Company uses only registered central clearing exchanges and well-established commercial banks as counterparties, monitors positions with individual counterparties and adjusts posted collateral as required. Financial Instruments The fair value of financial instruments for which it is practicable to estimate that value is disclosed either in the body of the financial statements or in the accompanying notes. RMBS, Eurodollar, Fed Funds and T-Note futures contracts, interest rate swaps, interest rate swaptions and TBA securities are accounted for at fair value in the balance sheets. The methods and assumptions used to estimate fair value for these instruments are presented in Note 12 of the financial statements. The estimated fair value of cash and cash equivalents, restricted cash, accrued interest receivable, 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 March 31, 2021 and December 31, 2020 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. Repurchase agreements are accounted for as collateralized financing transactions, which are carried at their contractual amounts, including accrued interest, as specified in the respective agreements. Reverse Repurchase Agreements and Obligations to Return Securities Borrowed under Reverse Repurchase Agreements The Company borrows securities to cover short sales of U.S. Treasury securities through reverse repurchase transactions under our master repurchase agreements. We account for these as securities borrowing transactions and recognize an obligation to return the borrowed securities at fair value on the balance sheet based on the value of the underlying borrowed securities as of the reporting date. The securities received as collateral in connection with our reverse repurchase agreements mitigate our credit risk exposure to counterparties. Our reverse repurchase agreements typically have maturities of 30 days or less. Manager Compensation The Company is externally managed by Bimini Advisors, LLC (the “Manager” or “Bimini Advisors”), a Maryland limited liability company and wholly-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 or incurred. Refer to Note 13 for the terms of the management agreement. 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”) under 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 assesses the likelihood, based on their technical merit, that uncertain 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 On January 1, 2020, we adopted Accounting Standards Update (“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 using an expected credit loss model (referred to as the current expected credit loss model). The Company’s adoption of this ASU did not have a material effect on its financial statements as its financial assets were already measured at fair value through earnings. In March 2020, the FASB issued ASU 2020-04 “ Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ” ASU 2020-04 provides optional expedients and exceptions to GAAP requirements for modifications on debt instruments, leases, derivatives, and other contracts, related to the expected market transition from the London Interbank Offered Rate (“LIBOR”), and certain other floating rate benchmark indices, or collectively, IBORs, to alternative reference rates. ASU 2020-04 generally considers contract modifications related to reference rate reform to be an event that does not require contract remeasurement at the modification date nor a reassessment of a previous accounting determination. The guidance in ASU 2020-04 is optional and may be elected over time, through December 31, 2022, as reference rate reform activities occur. The Company does not believe the adoption of this ASU will have a material impact on its consolidated financial statements. In January 2021, the FASB issued ASU 2021-01 “Reference Rate Reform (Topic 848). ASU 2021-01 expands the scope of ASC 848 to include all affected derivatives and give market participants the ability to apply certain aspects of the contract modification and hedge accounting expedients to derivative contracts affected by the discounting transition. In addition, ASU 2021-01 adds implementation guidance to permit a company to apply certain optional expedients to modifications of interest rate indexes used for margining, discounting or contract price alignment of certain derivatives as a result of reference rate reform initiatives and extends optional expedients to account for a derivative contract modified as a continuation of the existing contract and to continue hedge accounting when certain critical terms of a hedging relationship change to modifications made as part of the discounting transition. The guidance in ASU 2021-01 is effective immediately and available generally through December 31, 2022, as reference rate reform activities occur. The Company does not believe the adoption of this ASU will have a material impact on its financial statements.

Disclosure of Repurchase Agreements [Abstract]
Repurchase Agreements and Other Borrowings	NOTE 3. REPURCHASE AGREEMENTS 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 March 31, 2021, the Company had met all margin call requirements. As of March 31, 2021 and December 31, 2020, 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 March 31, 2021 Fair market value of securities pledged, including accrued interest receivable $ 58,219 $ 2,288,135 $ 1,316,896 $ 622,666 $ 4,285,916 Repurchase agreement liabilities associated with these securities $ 53,526 $ 2,233,561 $ 1,289,617 $ 604,976 $ 4,181,680 Net weighted average borrowing rate 0.24% 0.18% 0.18% 0.18% 0.18% December 31, 2020 Fair market value of securities pledged, including accrued interest receivable $ - $ 2,112,969 $ 1,560,798 $ 55,776 $ 3,729,543 Repurchase agreement liabilities associated with these securities $ - $ 2,047,897 $ 1,494,500 $ 53,189 $ 3,595,586 Net weighted average borrowing rate - 0.23% 0.22% 0.30% 0.23% In addition, cash pledged to counterparties for repurchase agreements was approximately $ 102.6 million and $ 58.8 million as of March 31, 2021 and December 31, 2020, respectively. 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 receivable and cash posted by the Company as collateral. At March 31, 2021, 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 $ 205.9 million. The Company did not have an amount at risk with any individual counterparty greater than 10% of the Company’s equity at March 31, 2021 and December 31, 2020.

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 included in restricted cash on our balance sheets. It is the Company's policy not to offset assets and liabilities associated with open derivative contracts. However, the Chicago Mercantile Exchange (“CME”) rules characterize variation margin transfers as settlement payments, as opposed to adjustments to collateral. As a result, derivative assets and liabilities associated with centrally cleared derivatives for which the CME serves as the central clearing party are presented as if these derivatives had been settled as of the reporting date.

Offsetting Assets and Liabilities [Text Block]	NOTE 6. OFFSETTING ASSETS AND LIABILITIES The Company’s derivative agreements and repurchase agreements and reverse repurchase agreements are subject to underlying agreements with master netting or similar arrangements, which provide for the right of offset in the event of default or in the event of bankruptcy of either party to the transactions. The Company reports its assets and liabilities subject to these arrangements on a gross basis.

Stock Repurchase Program 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. On February 8, 2018, the Board of Directors approved an increase in the stock repurchase program for up to an additional 4,522,822 shares of the Company's common stock. Coupled with the 783,757 shares remaining from the original 2,000,000 share authorization, the increased authorization brought the total authorization to 5,306,579 shares, representing 10% of the Company’s then outstanding share count. As part of the stock repurchase program, shares may be purchased in open market transactions, block purchases, through privately negotiated transactions, or pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Open market repurchases will be made in accordance with Exchange Act Rule 10b-18, which sets certain restrictions on the method, timing, price and volume of open market stock repurchases. 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 stock repurchase program through March 31, 2021, the Company repurchased a total of 5,685,511 shares at an aggregate cost of approximately $ 40.4 million, including commissions and fees, for a weighted average price of $ 7.10 per share.

STOCK INCENTIVE PLAN	Mar. 31, 2021
Employee Benefits And Share Based Compensation [Abstract]
Stock incentive Plan	NOTE 8. STOCK INCENTIVE PLAN In October 2012, the Company’s Board of Directors adopted and Bimini, then the Company’s sole stockholder, approved, the Orchid Island Capital, Inc. 2012 Equity Incentive Plan (the “Incentive Plan”) to recruit and retain employees, directors and other service providers, including employees of the Manager and other affiliates. The Incentive Plan provides for the award of stock options, stock appreciation rights, stock award, performance units, other equity-based awards (and dividend equivalents with respect to awards of performance units and other equity-based awards) and incentive awards. The Incentive Plan is administered by the Compensation Committee of the Company’s Board of Directors except that the Company’s full Board of Directors will administer awards made to directors who are not employees of the Company or its affiliates. The Incentive Plan provides for awards of up to an aggregate of 10% of the issued and outstanding shares of our common stock (on a fully diluted basis) at the time of the awards, subject to a maximum aggregate 4,000,000 shares of the Company’s common stock that may be issued under the Incentive Plan. Performance Units The Company has issued, and may in the future issue additional, performance units under the Incentive Plan to certain executive officers and employees of its Manager. “Performance Units” vest after the end of a defined performance period, based on satisfaction of the performance conditions set forth in the performance unit agreement. When earned, each Performance Unit will be settled by the issuance of one share of the Company’s common stock, at which time the Performance Unit will be cancelled. The Performance Units contain dividend equivalent rights, which entitle the Participants to receive distributions declared by the Company on common stock, but do not include the right to vote the underlying shares of common stock. Performance Units are subject to forfeiture should the participant no longer serve as an executive officer or employee of the Company or the Manager. Compensation expense for the Performance Units is recognized over the remaining vesting period once it becomes probable that the performance conditions will be achieved. The following table presents information related to Performance Units outstanding during the three months ended March 31, 2021 and 2020.

The book value impairment event occurred when the Company's book value per share declined by more than 15% during the quarter ended March 31, 2020 and the Company's book value per share decline from January 1, 2020 to June 30, 2020 was more than 10%. The Plans provide that if such a book value impairment event occurs, then the number of outstanding Performance Units that are outstanding as of the last day of such two-quarter period shall be reduced by 15%. Stock Awards The Company has issued, and may in the future issue additional, immediately vested common stock under the Incentive Plan to certain executive officers and employees of its Manager. The following table presents information related to fully vested common stock issued during the three months ended March 31, 2021 and 2020. All of the fully vested shares of common stock issued during the three months ended March 31, 2021, and the related compensation expense, were granted with respect to service performed during the previous fiscal year. ($ in thousands, except per share data) Three Months Ended March 31, 2021 2020 Fully vested shares granted 137,897 - Weighted average grant date price per share $ 5.88 - Compensation expense related to fully vested shares of common stock awards (1) $ 811 $ - The awards issued during the three months ended March 31, 2021 were granted with respect to service performed in 2020. Approximately $600,000 of compensation expense related to the 2021 awards was accrued and recognized in 2020. Deferred Stock Units Non-employee directors began to receive a portion of their compensation in the form of deferred stock unit awards (“DSUs”) pursuant to the Incentive Plan beginning with the awards for the second quarter of 2018. Each DSU represents a right to receive one share of the Company’s common stock. The DSUs are immediately vested and are settled at a future date based on the election of the individual participant. The DSUs contain dividend equivalent rights, which entitle the participant to receive distributions declared by the Company on common stock. These dividend equivalent rights are settled in cash or additional DSUs at the participant’s election. The DSUs do not include the right to vote the underlying shares of common stock. The following table presents information related to the DSUs outstanding during the three months ended March 31, 2021 and 2020.

Earnings Per Share (EPS)	NOTE 11. EARNINGS PER SHARE (EPS) The Company had dividend eligible Performance Units and Deferred Stock Units that were outstanding during the three months ended March 31, 2021 and 2020. The basic and diluted per share computations include these unvested Performance Units and Deferred Stock Units if there is income available to common stock, as they have dividend participation rights. The unvested Performance Units and Deferred Stock Units have no contractual obligation to share in losses. Because there is no such obligation, the unvested Performance Units and Deferred Stock Units are not included in the basic and diluted EPS computations when no income is available to common stock even though they are considered participating securities.

FAIR VALUE	3 Months Ended
FAIR VALUE	Mar. 31, 2021
Fair Value Disclosures [Abstract]
Fair Value	NOTE 12. FAIR VALUE The framework for using fair value to measure assets and liabilities defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price). A fair value measure should reflect the assumptions that market participants would use in pricing the asset or liability, including 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 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 RMBS and TBA securities are 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. The Company and the independent pricing sources use various valuation techniques to determine the price of the Company’s securities. These techniques include observing the most recent market for like or identical assets (including security coupon, maturity, yield, and prepayment speeds), spread pricing techniques to determine market credit spreads (option adjusted spread, zero volatility spread, spread to the U.S. Treasury curve or spread to a benchmark such as a TBA), and model driven approaches (the discounted cash flow method, Black Scholes and SABR models which rely upon observable market rates such as the term structure of interest rates and volatility). The appropriate spread pricing method used is based on market convention. The pricing source determines the spread of recently observed trade activity or observable markets for assets similar to those being priced. The spread is then adjusted based on variances in certain characteristics between the market observation and the asset being priced. Those characteristics include: type of asset, the expected life of the asset, the stability and predictability of the expected future cash flows of the asset, whether the coupon of the asset is fixed or adjustable, the guarantor of the security if applicable, the coupon, the maturity, the issuer, size of the underlying loans, year in which the underlying loans were originated, loan to value ratio, state in which the underlying loans reside, credit score of the underlying borrowers and other variables if appropriate. The fair value of the security is determined by using the adjusted spread. The Company’s futures contracts are Level 1 valuations, as they are exchange-traded instruments and quoted market prices are readily available. Futures contracts are settled daily. The Company’s interest rate swaps and interest rate swaptions are Level 2 valuations. The fair value of interest rate swaps is determined using a discounted cash flow approach using forward market interest rates and discount rates, which are observable inputs. The fair value of interest rate swaptions is determined using an option pricing model. RMBS (based on the fair value option), derivatives and TBA securities were recorded at fair value on a recurring basis during the three months ended March 31, 2021 and 2020. 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 possible, 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 observable data for similar assets. The following table presents financial assets (liabilities) measured at fair value on a recurring basis as of March 31, 2021 and December 31, 2020. (in thousands) Quoted Prices in Active Significant Markets for Other Significant Identical Observable Unobservable Assets Inputs Inputs (Level 1) (Level 2) (Level 3) March 31, 2021 Mortgage-backed securities $ - $ 4,338,536 $ - Interest rate swaps - 25,254 - Interest rate swaptions - 23,586 - Interest rate floors - 2,399 - TBA securities - 9,456 - December 31, 2020 Mortgage-backed securities $ - $ 3,726,895 $ - Interest rate swaps - (24,704) - Interest rate swaptions - 9,703 - TBA securities - 2,773 - During the three months ended March 31, 2021 and 2020, there were no transfers of financial assets or liabilities between levels 1, 2 or 3.

RELATED PARTY TRANSACTIONS	Mar. 31, 2021
Related Party Transactions [Abstract]
Related Party Transactions	NOTE 13. RELATED PARTY TRANSACTIONS Management Agreement The Company is externally managed and advised by Bimini Advisors, LLC (the “Manager”) pursuant to the terms of a management agreement. The management agreement has been renewed through February 20, 2022 and provides for automatic one-year extension options thereafter and is subject to certain termination rights. Under the terms of the management agreement, the Manager is responsible for administering the business activities and day-to-day operations of the Company.

BASIS OF PRESENTATION (Policies)	3 Months Ended
BASIS OF PRESENTATION (Policies)	Mar. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation and Use of Estimates The accompanying unaudited 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 include 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. Operating results for the three month period ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. The balance sheet at December 31, 2020 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.
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 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 differ from those estimates. The significant estimates affecting the accompanying financial statements are the fair values of RMBS and derivatives. Management believes the estimates and assumptions underlying the financial statements are reasonable based on the information available as of March 31, 2021.
Variable Interest Entity [Policy Text Block]	Variable Interest Entities (“VIEs”) We obtain interests in VIEs through our investments in mortgage-backed securities. Our interests in these VIEs are passive in nature and are not expected to result in us obtaining a controlling financial interest in these VIEs in the future. As a result, we do not consolidate these VIEs and we account for our interest in these VIEs as mortgage-backed securities. See Note 2 for additional information regarding our investments in mortgage-backed securities. Our maximum exposure to loss for these VIEs is the carrying value of the mortgage-backed securities.
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 other borrowings, and interest rate swaps and other derivative instruments. The following table provides a reconciliation of cash, cash equivalents, 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) March 31, 2021 December 31, 2020 Cash and cash equivalents $ 211,436 $ 220,143 Restricted cash 117,155 79,363 Total cash, cash equivalents and restricted cash $ 328,591 $ 299,506 The Company maintains cash balances at three banks and excess margin on account with two exchange clearing members. 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. Restricted 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 banks and exchange clearing members and believes that 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”) residential mortgage backed certificates issued by Freddie Mac, Fannie Mae or Ginnie Mae (“RMBS”), collateralized mortgage obligations (“CMOs”), interest-only (“IO”) securities and inverse interest-only (“IIO”) securities representing interest in or obligations backed by pools of RMBS. We refer to RMBS and CMOs as PT RMBS. We refer to IO and IIO securities as structured RMBS. The Company has elected to account for its investment in RMBS under the fair value option. Electing the fair value option requires the Company to record changes in fair value in the 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 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. Fair value is defined as 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 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 repayments are reflected in unrealized gains (losses) on RMBS in the 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 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 for future reporting periods 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 RMBS during each reporting period are recorded in earnings and reported as unrealized gains or losses on mortgage-backed securities in the accompanying statements of operations.
Derivative Financial Instruments	Derivative and Other Hedging Instruments The Company uses derivative and other hedging 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”), Fed Funds and Eurodollar futures contracts, short positions in U.S. Treasury securities, interest rate swaps, options to enter in interest rate swaps (“interest rate swaptions”) and “to-be-announced” (“TBA”) securities transactions, but the Company may enter into other derivative and other hedging instruments in the future. The Company accounts for TBA securities as derivative instruments. Gains and losses associated with TBA securities transactions are reported in gain (loss) on derivative instruments in the accompanying statements of operations. Derivative and other hedging instruments are carried at fair value, and changes in fair value are recorded in earnings for each period. The Company’s derivative financial instruments are not designated as hedge accounting relationships, but rather are used as economic hedges of its portfolio assets and liabilities. Holding derivatives creates exposure to credit risk related to the potential for failure on the part of counterparties and exchanges to honor their commitments. 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. The Company’s derivative agreements require it to post or receive collateral to mitigate such risk. In addition, the Company uses only registered central clearing exchanges and well-established commercial banks as counterparties, monitors positions with individual counterparties and adjusts posted collateral as required.
Financial Instruments	Financial Instruments The fair value of financial instruments for which it is practicable to estimate that value is disclosed either in the body of the financial statements or in the accompanying notes. RMBS, Eurodollar, Fed Funds and T-Note futures contracts, interest rate swaps, interest rate swaptions and TBA securities are accounted for at fair value in the balance sheets. The methods and assumptions used to estimate fair value for these instruments are presented in Note 12 of the financial statements. The estimated fair value of cash and cash equivalents, restricted cash, accrued interest receivable, 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 March 31, 2021 and December 31, 2020 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. Repurchase agreements are accounted for as collateralized financing transactions, which are carried at their contractual amounts, including accrued interest, as specified in the respective agreements.
Reverse Repurchase Agreements	Reverse Repurchase Agreements and Obligations to Return Securities Borrowed under Reverse Repurchase Agreements The Company borrows securities to cover short sales of U.S. Treasury securities through reverse repurchase transactions under our master repurchase agreements. We account for these as securities borrowing transactions and recognize an obligation to return the borrowed securities at fair value on the balance sheet based on the value of the underlying borrowed securities as of the reporting date. The securities received as collateral in connection with our reverse repurchase agreements mitigate our credit risk exposure to counterparties. Our reverse repurchase agreements typically have maturities of 30 days or less.
Management Fees	Manager Compensation The Company is externally managed by Bimini Advisors, LLC (the “Manager” or “Bimini Advisors”), a Maryland limited liability company and wholly-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 or incurred. Refer to Note 13 for the terms of the management agreement.
Earnings Per Share	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”) under 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 assesses the likelihood, based on their technical merit, that uncertain 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 Pronouncements On January 1, 2020, we adopted Accounting Standards Update (“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 using an expected credit loss model (referred to as the current expected credit loss model). The Company’s adoption of this ASU did not have a material effect on its financial statements as its financial assets were already measured at fair value through earnings. In March 2020, the FASB issued ASU 2020-04 “ Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ” ASU 2020-04 provides optional expedients and exceptions to GAAP requirements for modifications on debt instruments, leases, derivatives, and other contracts, related to the expected market transition from the London Interbank Offered Rate (“LIBOR”), and certain other floating rate benchmark indices, or collectively, IBORs, to alternative reference rates. ASU 2020-04 generally considers contract modifications related to reference rate reform to be an event that does not require contract remeasurement at the modification date nor a reassessment of a previous accounting determination. The guidance in ASU 2020-04 is optional and may be elected over time, through December 31, 2022, as reference rate reform activities occur. The Company does not believe the adoption of this ASU will have a material impact on its consolidated financial statements. In January 2021, the FASB issued ASU 2021-01 “Reference Rate Reform (Topic 848). ASU 2021-01 expands the scope of ASC 848 to include all affected derivatives and give market participants the ability to apply certain aspects of the contract modification and hedge accounting expedients to derivative contracts affected by the discounting transition. In addition, ASU 2021-01 adds implementation guidance to permit a company to apply certain optional expedients to modifications of interest rate indexes used for margining, discounting or contract price alignment of certain derivatives as a result of reference rate reform initiatives and extends optional expedients to account for a derivative contract modified as a continuation of the existing contract and to continue hedge accounting when certain critical terms of a hedging relationship change to modifications made as part of the discounting transition. The guidance in ASU 2021-01 is effective immediately and available generally through December 31, 2022, as reference rate reform activities occur. The Company does not believe the adoption of this ASU will have a material impact on its financial statements.
