Citi will settle stablecoin payments for merchants who never hold one, and neither company names the token

What happened

Citi and Coinbase announced two products on 28 September 2026, both launching first in the United States. Coinbase has selected Citi's Virtual Account Wallet, part of its banking-as-a-service business, to power Coinbase Virtual Accounts, which give Coinbase's payments customers "bank-account-like functionality to accept, hold, and pay funds, with incoming fiat automatically converted into stablecoins". In the other direction, Citi's institutional clients will be able to accept stablecoin payments at checkout through Spring by Citi, its payment acceptance platform. Coinbase Payments powers the acceptance, the payment is converted to fiat, and Citi settles "as the bank of record". Citi's release says merchants can reach "over 150 million stablecoin holders globally without needing to hold, custody or manage digital assets directly". Shahmir Khaliq, Citi's head of Services, called the arrangement "a foundational service for a leading virtual asset service provider like Coinbase". The release says Citi moves approximately $6 trillion a day.

Why it matters

The two products run in opposite directions. The merchant product turns a stablecoin into dollars before the merchant sees it, so the merchant carries no token and deals only with its bank. The virtual accounts turn dollars into stablecoins the moment they arrive, so the balance a customer holds is a token rather than a deposit. On the release's description, the fiat passes through Citi's rails and the balance sits in a stablecoin. That is where the money is made. A payment stablecoin may not pay its holder interest under the GENIUS Act, so the income on the reserves behind those balances goes to the issuer and the partners it shares it with. Blockhead notes that Coinbase earns a share of USDC reserve income. Citi sits at both ends: its rails carry the merchant's dollars out of the token and the account holder's dollars into one, and neither release says what it charges for either.

What is not settled

Neither company's text names a stablecoin, gives pricing or names a launch customer, and Blockhead says so. The 150 million holders are the companies' figure, with no source given. Coinbase's own post could not be read, because coinbase.com refused the request. It is known here only through Markets Media, which reproduced it under "Source: Coinbase", and PYMNTS, which reported it. The two texts do not agree on who said what. Citi's release gives "Our goal is to build the next generation of payments infrastructure that our clients need" to Ashish Bajaj, its head of Services for North America. Coinbase's post, on both reports of it, gives the sentence to Debopama Sen, head of payments, and drops "that our clients need". Citi's text of Coinbase's Alec Lovett begins "Clients building on Coinbase", Coinbase's "Fintechs building on Coinbase". Which version was said, and by whom, the documents do not settle.
