Citi × Coinbase: 3.75% USDC Yield Accounts + Stablecoin Checkout

Coinbase and Citi have moved their stablecoin partnership from planning to two live, U.S.-first business products. Coinbase Virtual Accounts use Citi’s Virtual Account Wallet to receive dollars and automatically convert them to USDC, while Spring by Citi lets institutional merchants accept stablecoin payments at checkout and receive fiat settlement without holding crypto.

A new business USDC benchmark

Coinbase Virtual Accounts advertise a 3.75% annual yield on USDC balances, as of September 29, 2026. The offer is for businesses, not a new retail savings product. It gives corporate users bank-account-like access while the balance and return sit on stablecoin infrastructure; readers can review Coinbase’s broader products in our Coinbase Review.

On the payment side, Coinbase handles the blockchain transaction and converts stablecoins to dollars. Citi then settles the funds as bank of record, so the merchant never needs to custody crypto.

Regulatory terms may still change

The GENIUS Act takes effect in January 2027, with Treasury implementation still moving through rulemaking. Whether Coinbase’s affiliate-funded 3.75% yield survives the final framework remains open.

Neither company disclosed transaction volumes, customer counts or pricing. The launches nevertheless add a visible institutional USDC yield benchmark and another example of stablecoin rails connecting treasury balances with everyday payments.
