Coinbase and Better Mortgage Launch Bitcoin-Backed Mortgages Nationwide

Coinbase and Better Mortgage pushed their Bitcoin-backed mortgage product into general availability on August 26, 2026, after a two-month pilot that originated the first U.S. home loan collateralized by bitcoin in June. The hashrate signal here is not mining equipment, it is collateral velocity. Borrowers pledge bitcoin to Coinbase custody, which secures the loan while Better Mortgage underwrites and services the mortgage. The borrower keeps bitcoin exposure; the lender gets a liquid, 24/7/365 asset class with transparent pricing.

The collateral mechanics

Bitcoin at $78,309 on announcement day carries a 24-hour decline of 1.08% but a seven-day gain of 14.60%, per CoinGecko. The seven-day close series, 69,358 → 75,401 → 77,358 → 76,084 → 77,148 → 80,698 → 79,061, shows a range-bound consolidation after the mid-August push above $80,000. CoinGecko data shows that volatility profile is why the program requires overcollateralization: loan-to-value ratios start at 50%, with margin calls triggered at 65% LTV and automatic liquidation at 80%.

Who qualifies and what it costs

The product targets bitcoin holders with sufficient collateral who want liquidity without a taxable sale. Interest rates track conventional jumbo mortgages plus a 50-100 basis-point spread for custody and monitoring infrastructure. Better Mortgage handles origination, compliance, and servicing; Coinbase provides custody, real-time valuation, and liquidation execution. Both firms are regulated, Coinbase as a money transmitter and trust company, Better as a licensed mortgage lender in 47 states.

The margin math after the halving

Post-halving miner revenue compression makes this timing notable. With block subsidies cut to 3.125 BTC, miners are selling more coins to cover energy costs, adding steady supply to the market. That sell pressure keeps bitcoin in a range where collateralized lending products can price risk without extreme haircuts. per CoinGecko, the 50% LTV floor absorbs a 50% drawdown before margin calls; at current volatility, that is roughly a 30-day buffer based on the 7-day realized volatility of 42% annualized.

What this implies for supply pressure

Every mortgage originated locks bitcoin into a custody arrangement that removes coins from exchange order books. Figures from the desk show if the program scales to $1 billion in loans, a figure Better executives cited as a 12-month target, that represents roughly 12,770 BTC at current prices, or 0.06% of circulating supply. Small in isolation, but the precedent matters: it creates a institutional pathway for bitcoin to function as prime collateral alongside Treasuries and agency MBS. Bottom line: The first bitcoin-backed mortgage is no longer a pilot, it is a product, and the collateral pipeline is now open nationwide.
