The Federal National Mortgage Association, better known as Fannie Mae, is reportedly moving to accept bitcoin-backed mortgages, a policy shift that would mark the first time a U.S. government-sponsored enterprise has recognized Bitcoin as eligible collateral in residential mortgage underwriting.
The announcement, initially circulated via Bitcoin Magazine's Telegram channel, signals that the $4 trillion institution could open the door for millions of American homebuyers to leverage their Bitcoin holdings without triggering a taxable liquidation event.

Fannie Mae's U.S. mortgage portfolio — now opening to bitcoin-backed loans
Fannie Mae is a government-sponsored enterprise (GSE) that underwrites or guarantees a significant share of all U.S. home loans. Its underwriting guidelines effectively set the floor for what thousands of banks and mortgage lenders across the country will accept from borrowers.
Full details of the policy mechanics, including what types of Bitcoin holdings qualify, loan-to-value thresholds, and any volatility haircuts applied to BTC collateral, have not yet been independently confirmed. Fannie Mae's existing selling guide on virtual currency has historically placed restrictions on how cryptocurrency assets can be treated in the underwriting process.
Why Fannie Mae's Move Carries More Weight Than Any Private Lender
Several private lenders, including United Wholesale Mortgage and fintech startup Milo, have offered bitcoin-collateralized mortgage products in recent years. Those loans, however, remained portfolio loans, held on the lender's own balance sheet and limited in scale.
A Fannie Mae endorsement changes the equation entirely. Conforming loans backed by Fannie Mae can be sold into the secondary mortgage market, dramatically expanding the pool of capital available and making bitcoin-backed lending scalable across the entire U.S. housing system.
Because Fannie Mae backs roughly half of all U.S. mortgages, its guidelines become the de facto national standard. When Fannie Mae updates its eligible-asset criteria, lenders nationwide adjust their products accordingly. Industry reporting from Scotsman Guide has noted that private crypto mortgage lenders have long sought deeper institutional backing to scale beyond niche offerings.
The practical implication for Bitcoin holders is significant: the ability to use BTC as proof-of-assets or collateral for a conforming mortgage would allow homebuyers to access housing finance without converting their Bitcoin to dollars, avoiding what would otherwise be a capital gains tax event.
Key caveats remain unclear. Conforming loan programs typically require conservative asset valuations, and Bitcoin's volatility could necessitate substantial valuation haircuts or custody requirements. Whether Fannie Mae will accept self-custodied Bitcoin or require institutional custody solutions has not been specified.
The Federal Policy Backdrop Behind the Shift
This reported move does not exist in a vacuum. It fits within a broader 2025-2026 U.S. policy trajectory toward treating Bitcoin as a legitimate financial asset at the federal level.
The Federal Housing Finance Agency (FHFA), which oversees both Fannie Mae and Freddie Mac, directed both GSEs in mid-2025 to develop plans for recognizing cryptocurrency as assets without requiring conversion to dollars. That directive laid the groundwork for any formal policy change.
The Trump administration has pushed aggressively on crypto integration into traditional finance, from the establishment of a Strategic Bitcoin Reserve via executive order to OCC and FDIC guidance allowing banks to custody digital assets. CNBC reported in November 2025 on the administration's rationale for allowing crypto-backed mortgages, framing it as part of a broader push to modernize housing finance.
Fannie Mae cannot move on a policy of this magnitude without at least tacit approval from the FHFA. The fact that the regulator itself initiated the directive to explore crypto-as-assets suggests this shift has institutional support rather than being an isolated corporate decision.
The immediate question is whether Freddie Mac, Fannie Mae's counterpart GSE, will follow with a parallel policy. Given that the FHFA's 2025 directive applied to both entities, a Freddie Mac announcement could follow on a similar timeline.

Fannie Mae would be the first government-sponsored enterprise to accept Bitcoin as mortgage collateral
If confirmed and implemented, this policy would represent the deepest integration of Bitcoin into the U.S. housing finance system to date. The implementation timeline, eligible asset thresholds, and custody requirements will determine how quickly the policy translates into real mortgage products available to borrowers.
