Coinbase and Morpho Make Bitcoin-Backed Loans More Predictable

Coinbase Puts a Clock on Bitcoin Loans

Coinbase already offered loans backed by bitcoin, but there was a catch. The interest rate floated with the market and there was no fixed due date. Borrowers could repay whenever they wanted as long as their positions remained healthy. The new Morpho Midnight product changes that arrangement by setting both the borrowing rate and maturity before the loan begins.

Morpho co-founder Merlin Egalite called it Coinbase’s first fixed-rate loan product, allowing customers to borrow USDC against BTC with a defined maturity. “Big news today: Coinbase launched its first fixed-rate loan product, and it’s powered by Morpho Midnight,” Egalite wrote on X. The pitch is pretty simple. Keep your bitcoin, borrow dollars in digital form against it, and know the borrowing cost beforehand.

Bitcoin Goes In and USDC Comes Out

Behind the scenes, Coinbase does considerably more than simply place bitcoin in a digital vault, according to company disclosures. Bitcoin held on Coinbase is wrapped into cbBTC, the company’s tokenized representation of the asset, before moving onchain to a Morpho smart contract on Base. That cbBTC becomes collateral, and the borrower receives USDC in a Coinbase account.

Coinbase is essentially the storefront, while Morpho supplies the credit machinery. Coinbase doesn’t carry the loan book itself. That setup resembles Coinbase’s existing loans powered by Morpho Blue, but Midnight changes one critical piece. Blue uses floating rates and open-ended repayment. Midnight uses fixed rates and fixed maturities. Morpho built Midnight alongside Blue rather than as its replacement.

The Interest Rate Comes From a Market

This is where things get more interesting. Morpho Midnight doesn’t work like a traditional bank deciding what rate to quote a customer. Borrowers and lenders trade standardized debt and credit units inside isolated markets, with the price of those units determining the borrowing rate.

One debt unit means a borrower owes 1 USDC at maturity. One credit unit means a lender is owed 1 USDC at the same point. Morpho’s documentation gives an example where purchasing a unit for 0.95 USDC that pays 1 USDC at maturity implies a return of about 5.26% before fees and losses.

Same-maturity units are interchangeable after borrowers and lenders match. Morpho designed the system that way partly to avoid thin markets where participants could get stuck with a single counterparty. Essentially, Coinbase aims to to wrap a familiar borrowing experience around an onchain fixed-income market.

Billions Are Already Sitting Behind the Experiment

The numbers get pretty wild. Morpho’s public dashboard, via Dune Analytics, recently showed roughly $3.60 billion in Coinbase-linked collateral, $1.56 billion in outstanding borrowing and $3.07 billion in total loan originations. About 53,000 borrowers were active.

This didn’t appear out of the blue. Coinbase launched Bitcoin-backed USDC loans through Morpho Blue on Jan. 16, 2025. Morpho launched Midnight on Base with cbBTC and USDC on July 21, 2026, specifically adding fixed-rate and fixed-term borrowing to its lending infrastructure. Now Coinbase is putting that machinery directly in front of its customers.

Fixed Rates Don’t Fix Bitcoin’s Price

There is still plenty of risk. Fixing the interest rate doesn’t fix the value of the bitcoin backing the loan. If bitcoin falls far enough and the loan-to-value ratio crosses the market’s limit, the borrower’s collateral can still be liquidated. Midnight also introduces something Coinbase’s open-ended Blue loans don’t have. The debt has a maturity date, and once that date arrives, repayment is due.

Crypto Credit Starts Looking More Like Regular Credit

That’s what makes the launch interesting beyond another Coinbase product announcement. Onchain borrowing has traditionally asked users to accept things that ordinary borrowers rarely encounter, including floating rates that can move constantly and loans governed directly by smart contracts.

Midnight keeps the smart contracts but makes the borrowing terms easier to recognize. A customer knows the rate, knows when the debt comes due and can access liquidity without first selling bitcoin. The machinery underneath is still pure crypto. Bitcoin becomes cbBTC, Base carries the transaction, Morpho runs the credit market and USDC lands back at Coinbase.

For the person taking the loan, though, the newest piece of crypto infrastructure may feel surprisingly old-fashioned.
