Coinbase Adds Fixed-Rate USDC Loans Against Bitcoin Through Morpho Midnight

Key Facts

Coinbase launched fixed-rate USDC loans backed by Bitcoin through Morpho Midnight, according to an announcement Morpho published on September 22, 2026. The rate and repayment date are set when each loan is made, giving borrowers a defined financing cost and term before they accept it. Customers reach the service in the Coinbase app; Morpho supplies the credit infrastructure and transactions settle on Base. The loan lets a Bitcoin holder obtain liquidity while retaining exposure to the asset pledged as collateral. Locking the borrowing rate, however, neither stabilizes the collateral’s market value nor removes the obligation to repay on time.

The new product sits alongside Coinbase’s existing variable-rate loans, making the reported lending figures important to distinguish. Morpho said active loans in the established offering exceeded $1.4 billion, backed by about $3 billion of collateral when it announced the launch. Those amounts describe the existing variable-rate book, not the volume of fixed-rate loans originated after the new option became available. The announcement gave no origination figure, borrower count or revenue figure for the fixed-rate product. Later reported growth in that product, rather than the size of the earlier book alone, will be the clearer test of commercial demand.

A fixed rate changes how uncertainty about borrowing costs is handled over the life of a loan. Variable-rate costs can respond to supply and demand in the lending market, whereas the fixed-rate loan locks its rate for a defined term. Coinbase says the rate displayed before borrowing is indicative and becomes final when the customer confirms the loan. Morpho says Midnight loans use market-based pricing between lenders and borrowers, so a fixed rate is not necessarily the cheaper rate. The useful comparison is the total cost of obtaining USDC for the period needed, taking the repayment date into account as well as interest.

The effective cost can differ from the displayed interest rate because fees affect the borrower’s repayment amount. Coinbase says a processing fee is added to principal at origination, so interest accrues on a balance larger than the cash the customer receives. A platform fee may also apply; Coinbase says it is paid up front on a fixed-rate loan when charged. Its guidance states that early repayment does not reduce the interest owed on this type of loan, a significant condition for a short-term borrower. Choosing between fixed and variable financing therefore requires reading the loan review screen and comparing total repayment amounts, not rates alone.

Bitcoin’s volatility remains a loan risk even when interest stays fixed for the entire term. Coinbase says the crypto collateral is locked on Morpho until the loan, accrued interest and fees are repaid. If the collateral falls in value, the debt rises relative to it and can reach the liquidation threshold applicable to that lending market. An unpaid fixed-rate loan can also become eligible for liquidation at maturity even if its collateral ratio is otherwise healthy. Borrowers consequently need to track collateral value, the amount due and the repayment deadline as risks distinct from a changing interest rate.

Morpho launched Midnight on July 21, 2026, as a fixed-rate, fixed-term lending market, initially on Base with a cbBTC/USDC market. Coinbase explains that cbBTC represents Bitcoin when it is used as collateral in onchain lending. Its established Morpho-backed loans carried variable rates, so the integration adds another financing structure within the same customer interface. Morpho describes the Coinbase integration as Midnight’s first enterprise-scale deployment, but that describes distribution rather than measured borrower demand. Turning technical availability into a sustained business will depend on lenders offering rates and maturities that customers accept.

Borrowing terms are not available equally to every customer, a constraint when assessing the product’s potential market. Coinbase says eligible customers include those in the United States outside New York, with limited access in the United Kingdom. It also says eligible collateral may differ between fixed-rate and variable-rate loans, so eligibility under one option does not establish eligibility under the other. Customers cannot hold both loan types against the same collateral simultaneously, and loans cannot be converted directly between them. Those restrictions mean a customer’s current borrowing arrangement and collateral holdings affect practical access to the new option.

For COIN shareholders, the launch adds a credit product to Coinbase’s existing relationship with crypto customers. Additional loans could increase app activity or related fees if enough borrowers use them, but that possibility requires supporting data. The launch announcement disclosed neither fixed-rate origination volume nor revenue, so the variable-rate book does not establish a specific earnings effect. It also does not show whether customers will add borrowing or choose fixed rates instead of variable loans they would have taken anyway. Later disclosures of balances and fees would provide a stronger basis for judging financial impact than the launch by itself.

A Bitcoin holder considering a USDC loan must weigh continued exposure to Bitcoin’s price against obtaining liquidity by pledging the asset. A fixed rate may suit someone who knows when the debt can be repaid and wants its financing cost set at the outset. The collateral nevertheless stays locked until obligations are met, and a borrower may need to add collateral or reduce debt if coverage deteriorates. Coinbase also says a fixed-rate loan must be repaid in full at maturity and cannot be converted directly into a variable-rate loan against the same collateral. Its terms prohibit using loan proceeds to trade on Coinbase, another constraint on the purpose of borrowing.

Morpho’s announcement gave no date for a separate report on uptake of Coinbase’s fixed-rate loans, leaving subsequent balance and revenue disclosures to test demand. For each borrower, the next firm date is the maturity specified in the loan agreement, when the full fixed-rate balance must be paid. Coinbase says it sends reminders 7 days, 3 days and 24 hours beforehand through its designated channels. Growing use on terms acceptable to borrowers would support a broader credit business, but assessing its scale requires published figures. Falling collateral values or missed repayments would expose the limits of the certainty a fixed borrowing rate provides.
