Invesco Mortgage Capital Inc. operates with $5.4 billion in repurchase agreement borrowings, creating continuous rollover exposure as the mortgage REIT refinances short-term debt against its mortgage-backed securities portfolio.
Repo agreements require daily or weekly renewal. Lenders can demand higher haircuts—the difference between collateral value and loan amount—or exit positions entirely during market stress. The 2020 pandemic spike saw repo haircuts on agency MBS jump from 2-3% to 5-8% within days, forcing multiple REITs into distressed asset sales.
Invesco's portfolio spans residential and commercial mortgage-backed securities, including agency-backed debt. Agency securities carry implicit government backing through Fannie Mae and Freddie Mac, typically securing lower haircuts than private-label MBS. Yet even agency repo markets can seize during volatility spikes.
The mortgage REIT sector maintains leverage ratios between 5:1 and 10:1, amplifying returns during stable periods but magnifying losses when asset values drop or financing costs rise. A 1% decline in MBS values triggers margin calls requiring immediate cash or collateral posting.
Recent Federal Reserve policy shifts add pressure. The central bank reduced its MBS holdings by $35 billion monthly through 2024, withdrawing a major bid from the market. Higher-for-longer interest rates through 2025 compressed REIT net interest margins as short-term repo rates rose faster than yields on existing MBS holdings.
Invesco must maintain relationships with multiple repo counterparties to ensure financing availability. Concentration risk emerges if one or two lenders provide the bulk of funding. Counterparty diversification costs more but reduces rollover vulnerability.
Book value volatility presents another concern. Mortgage REITs mark portfolios to market quarterly. Unrealized losses don't trigger immediate cash needs but erode equity cushions that absorb potential haircut increases. A 10% book value decline on $5.4 billion in repo debt could require $540 million in additional equity or force asset liquidation.
Credit-sensitive MBS and non-agency securities carry higher yields but face steeper haircut increases during risk-off periods. Agency MBS offer more stable financing but lower return spreads in the current rate environment.
