The U.S. mortgage market is about to test Bitcoin's stability with a federal backstop. Coinbase and mortgage lender Better are launching loans that use Bitcoin as collateral but avoid the typical crypto-lending pitfall of forced liquidations. Borrowers keep their Bitcoin even during a price crash, provided they make their monthly payments.
The structure relies on extreme conservatism. A borrower must pledge $500,000 in Bitcoin for a $200,000 loan - a 40% loan-to-value ratio that acts as a massive volatility cushion.
Steve, Presidio Bitcoin Jam:
- The eye-popping thing about this is it's a Bitcoin-backed loan.
- But if the price of Bitcoin goes down, you don't have to pony up more Bitcoin.
The transformative risk-shift lies downstream. Underwriters are designing these mortgages to be eligible for purchase by Fannie Mae, the government-sponsored enterprise. This moves the ultimate default risk from the crypto exchange into the heart of the federally backed housing system.
This banking integration arrives as other voices warn of fiat systems under wartime stress. On Rabbit Hole Recap, Marty Bent argues central banks are debasing currency to fund expanding global conflicts, making Bitcoin a critical hedge. Coinbase’s mortgage play suggests an opposite institutional bet: that Bitcoin is stable enough to be securitized by the very state its proponents often distrust.
The product targets a specific dilemma - the Bitcoin holder with substantial paper wealth but little cash flow, who wants to avoid a massive capital gains tax hit from selling. It’s a calculated wager that Bitcoin’s long-term floor is high enough for the government to underwrite.
