21st Century Mortgage Act of 2025

This bill allows borrowers to count digital assets (like cryptocurrency) held in secure custody as part of their mortgage reserves, without converting them to U.S. dollars. It directly affects borrowers with digital assets and requires Fannie Mae (Federal National Mortgage Association) and Freddie Mac (Federal Home Loan Mortgage Corporation) to adjust their risk assessments for these assets. Key provisions include applying adjustments for market volatility and asset concentration, requiring periodic reviews of risk models, and mandating board and agency approval before implementing assessment methods. The bill defines "digital assets" to exclude non-fungible items like collectibles and specifies secure custody requirements for inclusion.
