Citi and Coinbase Expand Partnership for USDC Stablecoin Payments to Corporate Clients

Stablecoin Checkout for Citi's Clients

Citi's corporate banking clients gained the ability to accept stablecoin payments at checkout on Monday, after Coinbase and the Wall Street bank expanded a partnership first struck in October 2025. Under the arrangement, Coinbase's payments infrastructure now plugs into Spring by Citi, the bank's merchant-payment platform: a customer pays in tokens pegged to the dollar, Coinbase converts them into fiat, and Citi settles the funds as the bank of record. Merchants never have to hold or manage digital assets themselves, which removes one of the main operational barriers that kept large enterprises away from on-chain settlement. The flow runs in the other direction as well. Citi's Virtual Account Wallet, part of its blockchain-era banking-as-a-service unit, now powers Coinbase Virtual Accounts — account structures that let businesses building on the exchange accept, hold and send money much like a traditional bank account, with incoming dollars automatically converted into stablecoins such as USDC. Both features go live in the United States first, and the companies said additional capabilities will follow in the coming months. Coinbase sized the addressable audience at more than 150 million stablecoin holders worldwide, a figure that frames the deal as retail-commerce infrastructure rather than an institutional pilot.

The two firms described the expansion in a joint statement as an effort to let clients move between traditional money and stablecoins without operating separate banking and crypto stacks. Debopama Sen, Citi's head of payments and services, said the goal is a “next generation of payments infrastructure” that works across both traditional and digital instruments, while Brett Tejpaul, who leads Coinbase Institutional, called Citi exactly the kind of regulated banking partner the digital asset economy needs to move from experimentation to everyday commerce. Stablecoins — tokens pegged to a traditional currency, usually the dollar — can settle around the clock, which is precisely the property Citi is buying access to. The deal lands amid a broad push by the bank into tokenized finance. Citi already runs Citi Token Services, which settles cross-border payments using tokenized deposits, and it has explored a joint stablecoin product alongside Deutsche Bank, Goldman Sachs and Bank of America since last year. In August, Citi said it would let institutional investors custody traditional assets and Bitcoin inside a single framework later in 2026. Alec Lovett, Coinbase's head of infrastructure product, framed the bank's contribution bluntly: fintechs building on the exchange have always needed a fast, compliant bridge between fiat and stablecoins, and Citi now provides that at scale.

Wire reports had flagged the tie-up earlier on Monday, hours before the full two-sided build-out was laid out, and the initial headlines captured only the merchant-facing half of the arrangement. Several material terms remain undisclosed: neither company has put a financial figure on the collaboration, committed to a timeline beyond the coming months, or said when the fiat-conversion features will reach customers outside the U.S. The U.S.-first scope also leaves open how non-dollar stablecoins fit in, since both announced products are framed around dollar-denominated payments. What is confirmed is Coinbase's push beyond trading revenue. Last week the exchange launched fixed-rate USDC loans collateralized by Bitcoin, powered by the lending protocol Morpho, and in August it debuted tokenized stocks on Base, its Ethereum layer-2 network, for non-U.S. users. Coinbase — America's largest crypto venue and a fixture of any Best Crypto Exchanges ranking — is positioning itself as a payments company as much as an exchange. For Citi, the deal closes an infrastructure gap: a bank without stablecoin rails risks watching corporate payment flows migrate to crypto-native processors.

Banks Race to Own Stablecoin Rails

Our read at COINOTAG: the three threads describe a single arc — stablecoins graduating from trading collateral to corporate payment infrastructure. On-chain venues such as Curve DAO (CRV) proved dollar settlement works years ago; tokenization platforms like Ondo Finance (ONDO) extended the model to real-world assets; now a global systemically important bank is wiring it into merchant checkout. In its official announcement, Coinbase brands the collaboration bank-grade fiat and stablecoin payments — yet discloses no fee schedule, no transaction volumes and no non-U.S. launch date, gaps we flag rather than infer around. The metric to watch next is whether Citi publishes stablecoin settlement volumes once the U.S. rollout matures.
