Citi Wires Stablecoin Checkout Into Its Merchant Payment Network

Citi's institutional clients can now take stablecoin payments at checkout and still get paid in dollars.

The rail runs through Spring by Citi, the bank's existing payment acceptance platform, with Coinbase Payments handling the crypto side. Coinbase's infrastructure converts the digital currency into fiat automatically, and Citi settles as the bank of record — so merchants never hold or custody a stablecoin themselves.

That puts stablecoins beside cards, bank transfers and commercial-bank money as one more way for a company to collect.

The other half of the deal

Coinbase also picked Citi's Virtual Account Wallet, part of the bank's Banking-as-a-Service stack, to power Coinbase Virtual Accounts. Incoming fiat in those accounts converts into stablecoins automatically, which Citi calls an industry first.

A rail aimed at 150 million holders

Citi says the checkout route lets merchants reach more than 150 million stablecoin holders worldwide without touching digital assets directly.

The bank moves roughly $6 trillion a day and banks 90% of the top eCommerce companies, so the distribution is already there. The rollout starts in the United States, with more capabilities promised in the coming months.

What is still missing

Citi and Coinbase have been working together since an October 2025 deal focused on fiat funding and withdrawals for Coinbase's on- and off-ramps.

The announcement leaves the terms that matter open — which stablecoins, which countries, which clients, and whether payments clear end to end through weekends and bank holidays. General availability and supported tokens are still unspecified.

Why traders should care

A weekend-proof dollar rail is what makes stablecoins genuinely useful to a treasurer, and Citi is testing that separately with tokenized bank deposits on Swift's Digital Ledger.

This deal puts stablecoins on the same shelf as cards at a bank most institutions already trust. The unanswered weekend question is the one to watch — that is when this stops looking like a pilot.
