Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business Operations	Organization and Business Operations Invesco Mortgage Capital Inc. (the “Company” or “we”) is a Maryland corporation primarily focused on investing in, financing and managing mortgage-backed securities ("MBS”) and other mortgage-related assets. As of March 31, 2023, we were invested in: • residential mortgage-backed securities (“RMBS”) that are guaranteed by a U.S. government agency such as the Government National Mortgage Association (“Ginnie Mae”), or a federally chartered corporation such as the Federal National Mortgage Association (“Fannie Mae”) or the Federal Home Loan Mortgage Corporation (“Freddie Mac”) (collectively “Agency RMBS”); • commercial mortgage-backed securities (“CMBS”) that are not guaranteed by a U.S. government agency or a federally chartered corporation (“non-Agency CMBS”); • RMBS that are not guaranteed by a U.S. government agency or a federally chartered corporation (“non-Agency RMBS”); and • other real estate-related financing arrangements. During the periods presented in these condensed consolidated financial statements, we also invested in: • a commercial mortgage loan; and • U.S. Treasury securities. We conduct our business through IAS Operating Partnership L.P. (the “Operating Partnership”) and have one operating segment. We are externally managed and advised by Invesco Advisers, Inc. (our “Manager”), a registered investment adviser and an indirect, wholly-owned subsidiary of Invesco Ltd. (“Invesco”), a leading independent global investment management firm. We elected to be taxed as a real estate investment trust (“REIT”) for U.S. federal income tax purposes under the provisions of the Internal Revenue Code of 1986. To maintain our REIT qualification, we are generally required to distribute at least 90% of our REIT taxable income to our stockholders annually. We operate our business in a manner that permits our exclusion from the “Investment Company” definition under the Investment Company Act of 1940, as amended (the “1940 Act”).

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Consolidation For all periods presented, common shares and per common share amounts have been adjusted on a retroactive basis to reflect our one-for-ten reverse stock split, which was effected following the close of business on June 3, 2022. Certain disclosures included in our Annual Report on Form 10-K are not required to be included on an interim basis in our quarterly reports on Form 10-Q. We have condensed or omitted these disclosures. Therefore, this Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022. Our condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and consolidate the financial statements of the Company and its controlled subsidiaries. All significant intercompany transactions, balances, revenues and expenses are eliminated upon consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for a fair statement of our financial condition and results of operations for the periods presented. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Examples of estimates include, but are not limited to, estimates of the fair values of financial instruments, interest income on mortgage-backed securities and allowances for credit losses. Actual results may differ from those estimates. Significant Accounting Policies There have been no changes to our accounting policies included in Note 2 to the consolidated financial statements of our Annual Report on Form 10-K for the year ended December 31, 2022.

Our repurchase agreements bear interest at a contractually agreed upon rate and generally have maturities ranging from one six onths. We account for our repurchase agreements as secured borrowings since we maintain effective control of the financed assets. Our repurchase agreements are subject to certain financial covenants. We were in compliance with all of these covenants as of March 31, 2023. The following tables summarize certain characteristics of our borrowings at March 31, 2023 and December 31, 2022.

Refer to Note 2 - "Summary of Significant Accounting Policies - Fair Value Measurements" of our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022 for a description of how we determine fair value. Agency RMBS collateral pledged is included in mortgage-backed securities on our condensed consolidated balance sheets. Cash collateral pledged on centrally cleared interest rate swaps is classified as restricted cash on our condensed consolidated balance sheets. Cash collateral pledged on repurchase agreements and TBAs accounted for as derivatives is classified as due from counterparties on our condensed consolidated balance sheets. Cash collateral held that is not restricted for use is included in cash and cash equivalents on our condensed consolidated balance sheets and the liability to return the collateral is included in collateral held payable. Non-cash collateral held is only recognized if the counterparty defaults or if we sell the pledged collateral. As of March 31, 2023 and December 31, 2022, we did not recognize any non-cash collateral held on our condensed consolidated balance sheets. $ in thousands As of Collateral Pledged March 31, 2023 December 31, 2022 Repurchase Agreements: Agency RMBS 5,085,592 4,439,583 Total repurchase agreements collateral pledged 5,085,592 4,439,583 Derivative Instruments: Cash 2,983 1,584 Restricted cash 127,038 103,246 Total derivative instruments collateral pledged 130,021 104,830 Total collateral pledged: Agency RMBS 5,085,592 4,439,583 Cash 2,983 1,584 Restricted cash 127,038 103,246 Total collateral pledged 5,215,613 4,544,413 As of Collateral Held March 31, 2023 December 31, 2022 Repurchase Agreements: Cash 221 4,892 Non-cash collateral 17,692 7,216 Total repurchase agreements collateral held 17,913 12,108 Derivative instruments: Cash 1,350 — Total derivative instruments collateral held 1,350 — Total collateral held: Cash 1,571 4,892 Non-cash collateral 17,692 7,216 Total collateral held 19,263 12,108 Repurchase Agreements Collateral pledged with our repurchase agreement counterparties is segregated in our books and records. The repurchase agreement counterparties have the right to resell and repledge the collateral posted but have the obligation to return the pledged collateral, or substantially the same collateral if agreed to by us, upon maturity of the repurchase agreement. Under the repurchase agreements, the respective lender retains the contractual right to mark the underlying collateral to fair value. We would be required to provide additional collateral to fund margin calls if the value of pledged assets declined. We intend to maintain a level of liquidity that will enable us to meet margin calls. The ratio of our total repurchase agreements collateral pledged to our total repurchase agreements outstanding was 106% as of March 31, 2023 (December 31, 2022: 105%) based on the fair value of the securities as reported in our condensed consolidated balance sheets. Interest Rate Swaps As of March 31, 2023 and December 31, 2022, all of our interest rate swaps were centrally cleared by a registered clearing organization such as the Chicago Mercantile Exchange (“CME”) and LCH Limited (“LCH”) through a Futures Commission Merchant (“FCM”). We are required to pledge initial margin and daily variation margin for our centrally cleared interest rate swaps that is based on the fair value of our contracts as determined by our FCM. Collateral pledged with our FCM is segregated in our books and records and can be in the form of cash or securities. Daily variation margin for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral and is recorded as gain (loss) on derivative instruments, net in our condensed consolidated statements of operations. Certain of our FCM agreements include cross default provisions. TBAs

See below for additional detail on our interest rate swaps with forward start dates. (2) Notional amount as of March 31, 2023 includes $6.3 billion of interest rate swaps whereby we pay interest at a fixed rate and receive interest at a floating rate and $1.8 billion of interest rate swaps whereby we pay interest at a floating rate and receive interest at a fixed rate. Notional amount as of December 31, 2022 includes $5.8 billion of interest rate swaps whereby we pay interest at a fixed rate and receive interest at a floating rate and $2.4 billion of interest rate swaps whereby we pay interest at a floating rate and receive interest at a fixed rate. Refer to Note 7 - "Collateral Positions" for further information regarding our collateral pledged to and received from our derivative counterparties. Interest Rate Swaps Our repurchase agreements are usually settled on a short-term basis ranging from one month to six months. At each settlement date, we typically refinance each repurchase agreement at the market interest rate at that time. Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposures to interest rate movements. To accomplish these objectives, we primarily use interest rate swaps as part of our interest rate risk management strategy. Under the terms of the majority of our interest rate swap contracts, we make fixed-rate payments to a counterparty in exchange for the receipt of floating-rate amounts over the life of the agreements without exchange of the underlying notional amount. To a lesser extent, we also enter into interest rate swap contracts whereby we make floating-rate payments to a counterparty in exchange for the receipt of fixed-rate amounts as part of our overall risk management strategy. Amounts recorded in accumulated other comprehensive income before we discontinued cash flow hedge accounting for our interest rate swaps are reclassified to interest expense on repurchase agreements on the condensed consolidated statements of operations as interest is accrued and paid on the related repurchase agreements over the remaining life of the interest rate swap agreements. We reclassified $4.5 million as a decrease to interest expense for the three months ended March 31, 2023 (March 31, 2022: $5.2 million as a decrease). As of March 31, 2023, $5.9 million (December 31, 2022: $10.4 million) of unrealized gains on discontinued cash flow hedges, net are still included in accumulated other comprehensive income and are expected to be reclassified as a decrease to interest expense, repurchase agreements over a period of time through December 15, 2023.

Offsetting [Abstract]
Offsetting Assets and Liabilities	Offsetting Assets and Liabilities Certain of our repurchase agreements and derivative transactions are governed by underlying agreements that generally provide for a right of offset under master netting arrangements (or similar agreements) in the event of default or in the event of bankruptcy of either party to the transactions. Assets and liabilities subject to such arrangements are presented on a gross basis in the condensed consolidated balance sheets. The following tables present information about the assets and liabilities that are subject to master netting arrangements (or similar agreements) and can potentially be offset on our condensed consolidated balance sheets at March 31, 2023 and December 31, 2022. The daily variation margin payment for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral. Our derivative liability of $7.9 million at March 31, 2023 (December 31, 2022: asset of $20,000) related to centrally cleared interest rate swaps is not included in the table below as a result of this characterization of daily variation margin.

Fair Value of Financial Instruments	Fair Value of Financial Instruments A three-level valuation hierarchy exists for disclosure of fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect our market assumptions. The three levels are defined as follows: • Level 1 Inputs – Quoted prices for identical instruments in active markets. • Level 2 Inputs – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. • Level 3 Inputs – Instruments with primarily unobservable value drivers. The following tables present our assets and liabilities measured at fair value on a recurring basis.

(2) Investments in unconsolidated ventures are valued using the net asset value (“NAV”) as a practical expedient and are not subject to redemption, although investors may sell or transfer their interest at the approval of the general partner of the underlying funds. As of December 31, 2022, we were invested in two unconsolidated ventures that were managed by an affiliate of our Manager. One of the unconsolidated ventures was dissolved during the first quarter of 2023. As of March 31, 2023, the remaining unconsolidated venture was in liquidation and plans to sell or settle its remaining investments as expeditiously as possible. The following table presents the carrying value and estimated fair value of our financial instruments that are not carried at fair value on the condensed consolidated balance sheets at March 31, 2023 and December 31, 2022.

This method discounts future estimated cash flows using rates we determined best reflect current market interest rates that would be offered for repurchase agreements with similar characteristics and credit quality.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Our Manager is at all times subject to the supervision and oversight of our board of directors and has only such functions and authority as we delegate to it. Under the terms of our management agreement, our Manager and its affiliates provide us with our management team, including our officers and appropriate support personnel. Each of our officers is an employee of our Manager or one of its affiliates. We do not have any employees. Our Manager is not obligated to dedicate any of its employees exclusively to us, nor is our Manager obligated to dedicate any specific portion of time to our business. During the three months ended March 31, 2023, we reimbursed our Manager $409,000 (March 31, 2022: $413,000) for costs of support personnel. Management Fee We pay our Manager a fee equal to 1.50% of our stockholders' equity per annum. For purposes of calculating the management fee, stockholders' equity is calculated as average month-end stockholders' equity for the prior calendar quarter as determined in accordance with U.S. GAAP. Stockholders' equity may exclude one-time events due to changes in U.S. GAAP and certain non-cash items upon approval by a majority of our independent directors. We do not pay any management fees on our investments in unconsolidated ventures that are managed by an affiliate of our Manager. Expense Reimbursement We are required to reimburse our Manager for operating expenses incurred on our behalf, including directors and officers insurance, accounting services, auditing and tax services, legal services, filing fees, and miscellaneous general and administrative costs. Our reimbursement obligation is not subject to any dollar limitation.

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity Preferred Stock In May 2022, our board of directors approved a share repurchase program for our Series B and Series C Preferred Stock. During the three months ended March 31, 2023, we did not repurchase any shares of preferred stock. As of March 31, 2023, we had authority to purchase 1,337,634 additional shares of our Series B Preferred Stock and 1,316,470 additional shares of our Series C Preferred Stock under the current share repurchase program. Holders of our Series B Preferred Stock are entitled to receive dividends at an annual rate of 7.75% of the liquidation preference of $25.00 per share or $1.9375 per share per annum until December 27, 2024. After December 27, 2024, holders are entitled to receive dividends at a floating rate equal to three-month London Interbank Offered Rate (“LIBOR”) plus a spread of 5.18% of the $25.00 liquidation preference per annum. Dividends are cumulative and payable quarterly in arrears. Holders of our Series C Preferred Stock are entitled to receive dividends at an annual rate of 7.50% of the liquidation preference of $25.00 per share or $1.875 per share per annum until September 27, 2027. After September 27, 2027, holders are entitled to receive dividends at a floating rate equal to three-month LIBOR plus a spread of 5.289% of the $25.00 liquidation preference per annum. Dividends are cumulative and payable quarterly in arrears. The United Kingdom Financial Conduct Authority, which regulates LIBOR, announced that it will cease to publish three-month USD LIBOR settings on July 1, 2023. We do not currently intend to amend our Series B or Series C Preferred Stock to change the existing USD LIBOR cessation fallback language. We expect our Series B and Series C Preferred Stock to pay floating rate dividends using a SOFR-based rate in place of three-month LIBOR. We have the option to redeem shares of our Series B Preferred Stock after December 27, 2024 and shares of our Series C Preferred Stock after September 27, 2027 for $25.00 per share, plus any accumulated and unpaid dividends through the date of the redemption. Shares of Series B and Series C Preferred Stock are not redeemable, convertible into or exchangeable for any other property or any other securities of the Company before those times, except under circumstances intended to preserve our qualification as a REIT or upon the occurrence of a change in control. Common Stock In May 2022, our board of directors approved a one-for-ten reverse split of outstanding shares of our common stock. The reverse stock split was effected following the close of business on June 3, 2022 (the “Effective Time”). At the Effective Time, every ten issued and outstanding shares of our common stock were converted into one share of our common stock. No fractional shares were issued in connection with the reverse stock split. Instead, each stockholder holding fractional shares received cash, in lieu of such fractional shares, in an amount determined based on the closing price of our common stock at the Effective Time. The reverse stock split applied to all of our outstanding shares of common stock and did not affect any stockholder’s ownership percentage of our common stock, except for changes resulting from the payment of cash for fractional shares. As of March 31, 2023, we may sell up to 13,069,931 shares of our common stock from time to time in at-the-market or privately negotiated transactions under our equity distribution agreement with placement agents. These shares are registered with the SEC under our shelf registration statement (as amended and/or supplemented). During the three months ended March 31, 2023, we sold 2,930,069 shares of common stock under our equity distribution agreement for proceeds of $35.8 million, net of approximately $482,000 in commissions and fees. We did not sell any shares of common stock under equity distribution agreements during the three months ended March 31, 2022. During the three months ended March 31, 2023 and 2022, we did not repurchase any shares of our common stock. As of March 31, 2023, we had authority to purchase 1,816,398 shares of our common stock through our common stock share repurchase program.

Accounting Policies [Abstract]
Basis of Presentation	For all periods presented, common shares and per common share amounts have been adjusted on a retroactive basis to reflect our one-for-ten reverse stock split, which was effected following the close of business on June 3, 2022. Certain disclosures included in our Annual Report on Form 10-K are not required to be included on an interim basis in our quarterly reports on Form 10-Q. We have condensed or omitted these disclosures. Therefore, this Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022.
Consolidation	Our condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and consolidate the financial statements of the Company and its controlled subsidiaries. All significant intercompany transactions, balances, revenues and expenses are eliminated upon consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for a fair statement of our financial condition and results of operations for the periods presented.
Use of Estimates	The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Examples of estimates include, but are not limited to, estimates of the fair values of financial instruments, interest income on mortgage-backed securities and allowances for credit losses. Actual results may differ from those estimates.
