Fannie Mae is opening a new route into housing finance for digital-asset holders, allowing borrowers to use Bitcoin and USDC held on Coinbase as collateral for single-family mortgages without selling those assets upfront. The program, developed with Coinbase and Better Home & Finance, creates a structure in which crypto can support a home loan while remaining in the borrower’s account.
The significance of the move goes beyond product design. For households whose wealth is concentrated in digital assets, the arrangement creates a way to access mortgage financing while preserving the tax treatment that could be affected by an immediate liquidation. At the same time, it introduces new questions for regulators, lenders and servicers around valuation, custody and consumer protection.
A new mortgage structure built around crypto custody
At the operational level, Coinbase provides the infrastructure and custodial channel through which the pledged digital assets are held, while Better Home & Finance, as an approved Fannie Mae mortgage seller, structures the loan itself. That setup shifts crypto from being a source of funds that must be sold into cash to being a pledged asset inside a more traditional mortgage workflow.
The model also differs in important ways from standard crypto-backed lending. Unlike many digital-asset credit products, this structure does not require margin calls or additional collateral simply because the market price of Bitcoin or USDC changes. Instead, liquidation is tied to borrower default rather than routine volatility, which changes how risk is managed for both the borrower and the lender.
The terms described in the reporting make that distinction clear. Borrowers can pledge Bitcoin and USDC held on Coinbase, but crypto cannot be used for earnest money in purchase transactions, and liquidation is reserved for delinquency scenarios comparable to a 60-day payment default. Mortgage pricing is also reported to sit about 0.5% to 1.5% above conventional 30-year mortgage rates, reflecting the extra complexity and risk embedded in the structure.
The real test will be supervision and consumer safeguards
This approach pushes digital assets deeper into a part of finance where operational discipline matters as much as innovation. Once crypto becomes part of mortgage underwriting, lenders and servicers need clear procedures for custody verification, asset monitoring, collateral reporting and borrower disclosures. What looks like a flexible financing channel on the surface quickly becomes a more demanding compliance exercise behind the scenes.
That is why the policy debate is likely to intensify as the program develops. Even if the structure protects borrowers from forced liquidations caused only by market swings, it does not remove the prudential need for transparent valuation, strong governance and careful consumer safeguards. The volatility of the underlying collateral still matters, even if the trigger for enforcement has been narrowed.
Lenders, servicers and institutional custodians will need to show that they can integrate crypto collateral into mortgage finance without weakening underwriting standards, disclosure quality or incident-response controls. How well they do that will determine whether this becomes a narrow niche product or a more durable bridge between digital assets and housing finance.
