Fannie Mae has agreed to back mortgages with Bitcoin and USDC, allowing borrowers to avoid selling their tokens and potentially triggering capital gains taxes while still securing the down payment. The move aligns with Fannie Mae's commitment to treating provable digital assets as acceptable support for conforming loans. The crypto-backed second lien is sized at roughly a 40% loan‑to‑value ratio, meaning a borrower could obtain about $100,000 loan against $250,000 worth of Bitcoin or USDC on deposit. The initiative targets would-be buyers who are asset rich, cash poor, particularly younger households with significant crypto holdings. Interest rates on the token-backed mortgages are expected to run modestly above standard 30-year fixed mortgages.
