Citi and Coinbase Launch Fiat Settlement for Stablecoin Merchant Payments in the United States

Coinbase has deepened its work with Citi to let businesses accept stablecoin payments while settling back to fiat, starting in the United States. For high-risk merchants and the PSPs that serve them, the point is not the branding — it is the plumbing: who holds the money, who converts it, and which bank sits in the middle.

1. Coinbase said in a Monday, Sept. 28 blog post that it will use Citi’s Virtual Account Wallet to power Coinbase Virtual Accounts. Those accounts let customers accept, hold, pay and automatically convert incoming fiat into stablecoins, with Citi providing the regulated banking infrastructure that connects the accounts to the global financial system.
2. Alec Lovett, head of infrastructure product at Coinbase, said the setup gives clients “a fast, compliant bridge between fiat and stablecoins” and “bank account-like functionality with the speed of stablecoins underneath it.” That matters because it describes the core merchant question here: can you move money without making the merchant run a crypto treasury operation?
3. Coinbase also adopted Spring by Citi, Citi’s payment acceptance platform for merchant acquiring, gateway technology and settlement. That lets Citi’s institutional clients accept stablecoin payments without holding or managing stablecoins themselves; Coinbase’s infrastructure converts the digital currency into fiat automatically, and Citi settles the funds as the bank of record.
4. Brett Tejpaul, head of Coinbase Institutional, said the collaboration gives Coinbase customers bank-grade fiat infrastructure on one side and Citi’s institutional clients low-friction stablecoin acceptance on the other, “without either side needing to build or manage a system they don’t need.” In practice, that is the merchant-acquiring pitch: keep the crypto exposure on the rails, not on the balance sheet.
5. The post said clients building on Coinbase can offer branded virtual accounts for accepting, holding and sending funds, automatically convert incoming fiat into stablecoins, and enable merchants to receive fiat settlement when customers pay in stablecoins. The initiatives will launch first in the United States.

Debopama Sen, head of payments, services at Citi, said the bank is focused on building payments infrastructure that operates across both traditional and digital payments instruments and networks. For PSPs and high-risk merchants, the practical takeaway is that Citi and Coinbase are trying to make stablecoin acceptance look less like a crypto stack and more like ordinary settlement, which is usually how these things get adopted.
