The U.S. government-sponsored mortgage system now accepts cryptocurrency as collateral. Fannie Mae began purchasing crypto-backed conforming loans in March 2026 through a partnership between Better Home & Finance and Coinbase, the first product of its kind in the $2.27 trillion annual U.S. mortgage origination market. The Federal Housing Finance Agency (FHFA), under Director William Pulte, formalized the framework in mid-2025, requiring 50–60% volatility haircuts on pledged digital assets held on regulated U.S. exchanges.
Separately, Figure crossed $1 billion in monthly blockchain-native mortgage originations in March 2026, placing it on a $12 billion annualized run rate. Better secured a $500 million credit facility from the Sky (formerly MakerDAO) stablecoin ecosystem to fund originations at rates over 100 basis points below traditional warehouse lines. Newrez, a top-25 U.S. lender, began accepting Bitcoin, Ethereum, and USD-pegged stablecoins for non-agency loan qualification in February 2026. Miami-based Milo crossed $100 million in cumulative crypto mortgage originations the same month.
Collectively, these developments mark the first systemic integration of digital assets into U.S. housing finance infrastructure—a $7.7 trillion residential mortgage market that underpins more than 80 million American homeowners.
On June 25, 2025, FHFA Director William Pulte directed Fannie Mae and Freddie Mac to draft proposals allowing mortgage lenders to count borrowers' cryptocurrency holdings as qualifying assets in underwriting. The directive specified that eligible assets must be stored on U.S.-regulated centralized exchanges and comply with applicable anti-money laundering (AML) laws.
The FHFA formalized requirements on July 3, 2025. Key parameters:
The practical effect: a borrower holding $200,000 in Bitcoin on Coinbase can claim approximately $80,000–$100,000 toward reserve requirements. This is a steep overcollateralization by conventional lending standards, where cash and equities receive 0–20% haircuts.
Fannie Mae began purchasing conforming loans with crypto-backed down payments on March 26, 2026. Freddie Mac has not yet launched an equivalent product, though it operates under the same FHFA directive.
The Better-Coinbase product, the first Fannie Mae-eligible crypto-backed mortgage, operates as a dual-loan structure:
Key structural features:
The structure insulates Fannie Mae from direct crypto volatility exposure. The GSE purchases only the first lien, which is collateralized by the property itself. The crypto exposure sits in the second lien, which is privately held.
Four distinct models have emerged in the crypto-mortgage space:
For context, the Mortgage Bankers Association projects total U.S. single-family mortgage originations at $2.27 trillion in 2026, up 8% year-over-year. Crypto-backed originations remain a fraction of this total, but the trajectory is steep.
On February 23, 2026, Better announced a strategic partnership with Framework Ventures to access up to $500 million in credit through the Sky (formerly MakerDAO) stablecoin ecosystem. Framework Ventures took a $45 million equity stake in Better simultaneously.
Structure details:
This represents the first deployment of tokenized DeFi capital by a conforming mortgage originator at institutional scale. The economic logic is straightforward: DeFi yield-seeking capital (Sky's USDS stablecoin holders earn approximately 6–8% APY) can be deployed as mortgage warehouse credit, potentially at lower cost than traditional bank warehouse lines that price off SOFR + spread.
Better also announced plans to launch a "Home Token"—a tokenized representation of its mortgage assets—though details remain sparse.
The crypto-mortgage convergence has generated bipartisan scrutiny:
Senate Banking Committee (Minority) Senators Jeff Merkley (D-OR), Elizabeth Warren (D-MA), Dick Durbin (D-IL), and Bernie Sanders (I-VT) sent two letters to FHFA Director Pulte:
Senator Merkley stated: "The 2008 crisis proved that lax financial practices around risky investments can blow up the housing market—and hardworking families in Oregon and across the country paid the price."
Industry Concerns:
Consumer Advocates:
Economist Peter Schiff argued that pledging bitcoin as a down payment means "if bitcoin crashes, the collateral vanishes, and default risk would rise with lenders stuck taking the loss."
| Asset Class | Typical Haircut | Reserve Credit per $100K | |---|---|---| | Cash / U.S. Treasuries | 0% | $100,000 | | Equities (diversified) | 10–25% | $75,000–$90,000 | | Bitcoin (BTC) | 50–60% | $40,000–$50,000 | | Ethereum (ETH) | Under review | TBD |
Current exposure is limited. Milo's $100 million cumulative volume, Better's early-stage program, and Newrez's non-agency product represent negligible systemic risk against a $7.7 trillion residential mortgage market. Even Figure's $12 billion annualized volume represents primarily blockchain-native origination infrastructure rather than crypto-collateralized lending.
However, the trajectory matters. Better estimates $40 billion in latent demand from crypto holders. If 45% of Gen Z and Millennial investors (52 million Americans) hold crypto—as Coinbase survey data suggests—and median home prices sit at $436,523, the addressable market is substantial.
The structural insulation matters: Fannie Mae's exposure is to the property (first lien), not the crypto (second lien). A Bitcoin crash would trigger losses in the privately held second lien, not in the GSE-backed first lien. This is meaningfully different from the 2008 scenario where toxic collateral existed within the GSE-purchased instruments themselves.
The integration of cryptocurrency into U.S. mortgage infrastructure has moved from theoretical to operational in under 12 months. The FHFA directive (June 2025), Fannie Mae product launch (March 2026), and DeFi credit facilities (February 2026) collectively represent the first institutional bridge between digital asset markets and the housing finance system.
The economic logic favoring adoption is clear: 52 million American crypto holders represent a borrower pool that traditional mortgage underwriting has historically excluded or underserved. Better's estimate of $40 billion in unrealized demand is unverified but directionally plausible given median home prices and crypto ownership demographics.
The counterargument—that volatile, uninsured digital assets have no place in federally backstopped housing finance—carries weight but applies primarily to direct GSE exposure. The current product architecture deliberately isolates crypto risk in privately held second liens.
What remains unclear is whether this structural separation will hold under stress. A severe crypto downturn coinciding with a housing correction—a scenario without historical precedent—would test both the dual-lien structure and servicer capacity to manage digital collateral. Until that scenario materializes, the market will continue expanding into a regulatory and actuarial vacuum.
