Coinbase Powers First Crypto-Backed Conforming Mortgages

Coinbase and Better Home & Finance have just made history by launching the first-ever conforming crypto-backed mortgage in the United States—a groundbreaking financial product that allows borrowers to use Bitcoin or USDC as collateral to secure a Fannie Mae-backed home loan without selling their crypto holdings.

This isn’t just a niche experiment—it’s a full-scale integration into the $12 trillion U.S. residential mortgage market, backed by the same federal infrastructure that underpins more than half of all American home purchases. The headline is historic. The mechanics underneath? That’s where the real story—and the real trade-offs—live.

Here’s how it works: Bitcoin is discounted to 40% of its market value for collateral purposes, while USDC is discounted to 80%. That means if you pledge $100,000 in Bitcoin, you’ll only get $40,000 in usable down payment credit. It’s a significant haircut—but it’s the price of admission to make this work for government-sponsored enterprises (GSEs) like Fannie Mae and Freddie Mac.

So what does it actually take to use crypto to buy a house under this framework? And what does this product’s very existence signal about where institutional mortgage infrastructure is heading?

Key Takeaways:

• Policy Trigger: FHFA Director Bill Pulte directed Fannie Mae and Freddie Mac on June 25, 2025, to develop crypto-as-asset underwriting guidelines, providing the regulatory foundation for this product.
• Haircut Mechanism: BTC is valued at 40% of market price; USDC at 80%. A $100,000 BTC position yields $40,000 in qualifying collateral.
• First Mover: Coinbase and Better Home & Finance are executing the first conforming loan under this structure; lender Newrez has since launched its own parallel crypto-backed program.
• Scope Limitation: Only assets held on U.S.-regulated exchanges with AML compliance and a 60-day holding history qualify—cold wallets, DeFi positions, and staked assets are excluded.

How the Loan Structure Actually Works

The product is structured as two instruments layered together: a primary conforming Fannie Mae-backed mortgage and a second mortgage covering the down payment, secured by pledged crypto collateral. Coinbase holds the pledged assets in custody; borrowers do not transfer ownership, but the collateral is encumbered for the loan’s duration.

The haircut is the defining constraint. To generate $80,000 in qualifying down payment credit using Bitcoin at the 40% valuation rate, a borrower must pledge $200,000 in BTC. USDC’s 80% rate is more capital-efficient; $100,000 in USDC yields $80,000 in usable collateral, but still demands a meaningful overcollateralization buffer.

Fannie Mae’s volatility haircut framework is designed precisely to absorb the asset class’s price swings without triggering forced liquidations on the borrower side. There are no margin calls. Collateral is not at risk from short-term price drops. The crypto position becomes actionable for the lender only after 60 or more days of delinquency, aligning with standard foreclosure timelines and deliberately decoupling the mortgage’s credit risk from crypto’s daily volatility.

Eligible assets must be held on a U.S.-regulated exchange with full AML compliance and a minimum 60-day documented holding history. Cold wallets are excluded. DeFi positions do not qualify. Staked assets are out. The framework is narrow by design; it trades flexibility for GSE compatibility, which is the only pathway to conforming status.

The policy architecture behind this traces directly to FHFA Director Pulte’s June 25, 2025, directive ordering Fannie Mae and Freddie Mac to develop formal underwriting guidelines for digital assets. Phase 1 framework proposals covering volatility treatment and documentation standards are currently under FHFA review, with a 6-to-12-month timeline before the rollout of Phase 2 criteria.

This is more than a product launch—it’s a signal. The mortgage market, one of the most conservative corners of American finance, is now officially open to crypto. And if history is any guide, where Fannie Mae and Freddie Mac go, the rest of the market soon follows.
