Coinbase's new Bitcoin-backed USDC loans come with a catch: even if your collateral is strong, missing the set repayment date can get your assets liquidated. The risk isn't just about Bitcoin's price anymore.
Coinbase's fixed-rate Bitcoin-backed USDC loans bring a new risk for borrowers. If you miss the repayment deadline, your collateral can be liquidated-even if Bitcoin's price hasn't dropped and your loan-to-value ratio is healthy. The risk now comes from the calendar, not just the market.
Repayment deadline is now a liquidation trigger
With variable-rate crypto loans, borrowers can pay back whenever they want. Coinbase's fixed-rate loans work differently. You have to repay the full amount by a set maturity date. If you don't, your loan can be liquidated, even if your Bitcoin collateral is still well above the required level. Morpho Midnight, the protocol behind Coinbase's fixed-rate loans, enforces this rule. So, paying on time is just as important as keeping your loan-to-value ratio in check.
If a fixed-rate loan is not repaid by its maturity date, Morpho protocol allows liquidation of the collateral even if the loan-to-value ratio remains healthy.
When the loan matures, your collateral isn't seized right away. But if you still owe money after the deadline, a liquidator can step in, pay off your debt, and take your collateral. This is a big change from most crypto loans, where liquidation usually happens only if your collateral value drops or your debt spikes. Here, the date on the calendar can put your assets at risk.
How liquidation works
Coinbase shows you an estimated interest rate before you confirm the loan. The final rate is locked in when you agree. You can't lower your interest by paying early, and you can't switch between fixed and variable rates after the loan starts. The maturity date is fixed. Coinbase says it sends reminders seven days, three days, and 24 hours before the loan is due. But it's still up to you to pay back the full amount on time.
Coinbase and industry reports say that at launch, you can only pick a repayment term ending either at the end of the current month or the end of the next month. "End of Month" means the last Friday of the month. This tight schedule means you have to watch the calendar closely. If you miss the deadline, your loan can be liquidated right away under Morpho's rules, no matter how healthy your collateral is. Before the maturity date, liquidation can still happen if your collateral drops in value or your debt gets too high. But the fixed-term model adds a new risk: time itself.
Unlike variable-rate crypto loans, fixed-rate loans on Coinbase powered by Morpho Midnight shift part of the risk from market volatility to strict calendar deadlines. This means that even well-collateralized positions can be liquidated solely due to missed repayment dates, emphasizing the importance of operational discipline for borrowers.
Who can use these loans and what are the terms?
Coinbase's fixed-rate Bitcoin-backed USDC loans are open to verified U.S. customers outside New York, and to a limited extent in the UK. Morpho requires Bitcoin as collateral for this launch. Coinbase says collateral options may differ between fixed and variable-rate loans. You can't switch an existing loan between rate types. The terms you get at the start-including the maturity date and total repayment-are final. The interest rate and borrowing limit are shown in the product interface and depend on the loan.
Coinbase's fixed-rate loans are different from other crypto lending products that only care about collateral health. The hard maturity date as a liquidation trigger means users have to manage a new kind of risk. This is a shift from perpetual futures contracts reported earlier, where there's no set expiration and liquidation only happens if the market moves against you.
What this means for borrowers
Fixed interest rates might look attractive, but the strict repayment schedule means you can lose your collateral just by missing a deadline. Coinbase's reminders may help, but it's still your job to pay on time. This setup could change how people plan for risk and liquidity when using crypto-backed loans.
Coinbase hasn't published exact numbers for interest rates, borrowing limits, or collateral requirements for these loans. The fixed-rate product sits next to variable-rate loans, which don't have the same deadline-driven liquidation risk. As of September 22, 2026, the fixed-rate loans are only available to some U.S. and UK users, and the terms could change.
By tying liquidation to the maturity date, Coinbase is changing how crypto lending platforms handle risk and enforce discipline. Borrowers get more predictable costs, but also face a new risk that isn't tied to the market. It's a reminder that users need to understand not just how collateral works, but also the rules that control loan agreements in crypto lending.
In most crypto lending, liquidation happens if your collateral drops too far compared to your debt. Fixed-rate loans with a hard maturity date add a second risk: time. Even if your collateral is strong, missing the deadline can mean losing your assets right away. This puts more pressure on borrowers to stay organized and plan ahead when using fixed-term crypto loans.
