Tokenized Collateral in Fannie Mae Mortgages: Tracing FHFA Directives to Legislative Proposals

The Coinbase-Better Home & Finance arrangement permits qualified borrowers to pledge Bitcoin or USDC as collateral for down-payment loans on Fannie Mae-backed properties, with rollout targeted for summer 2026. This structure follows the June 2025 FHFA directive instructing Fannie Mae and Freddie Mac to incorporate unconverted cryptocurrency holdings into mortgage risk assessments. Primary documentation from the FHFA order emphasizes expanded asset recognition without mandatory liquidation, aligning with earlier guidance issued under the prior administration. Parallel developments include Newrez’s February 2025 policy allowing crypto qualification and the July 2025 introduction of the 21st Century Mortgage Act by Senator Cynthia Lummis, which seeks statutory codification of such criteria. A July 2025 letter from five senators to FHFA Director Bill Pulte raises concerns over housing-market stability, citing volatility risks and potential systemic exposure. The Coinbase initiative therefore sits at the intersection of administrative reinterpretation of existing GSE charters and proposed statutory updates, illustrating how regulatory language on asset eligibility can migrate from agency circulars into private-sector product design without requiring immediate legislative change. Multiple congressional records show both support for modernizing underwriting and caution regarding unhedged digital-asset price movements, underscoring divergent institutional assessments of credit-risk parameters.
