Coinbase and Citigroup are expanding a partnership built around stablecoin payments for businesses, introducing new tools on both sides that connect traditional banking infrastructure with digital dollar rails.

Stablecoins are digital tokens designed to track the value of a traditional currency, most commonly the US dollar, and are increasingly being built into business payment flows as a way to move dollar value over blockchain rails.

The two firms first teamed up in October 2025 link fiat payments with crypto infrastructure. The expansion announced this week gives corporate clients of each company more ways to move between traditional money and stablecoins. Details of the rollout were outlined in an official Coinbase blog post.

In an X post published on September 28, 2026, Coinbase said:

We're bringing stablecoins into the banking system with @Citi. That means instant stablecoin acceptance for institutions – all on bank-grade, regulated infrastructure. The next step for stablecoins becoming everyday money. pic.twitter.com/9ftQ50yl5y

How the Payments Work

Coinbase will use Citi's Virtual Account Wallet to power its Coinbase Virtual Accounts product. The service lets business customers accept, hold, and pay out fiat currency, while incoming funds can also be automatically converted into stablecoins. The design offers companies a bank-like account experience without requiring them to manage crypto directly, with the crypto-side mechanics handled by the platform rather than the client's own team.

On the other side, Citi's institutional clients will be able to accept stablecoin payments through the Spring by Citi platform, with Coinbase handling the stablecoin payment rails. Coinbase then converts the digital assets back into fiat, and Citi settles the funds as the bank of record, meaning merchants keep their usual settlement process. For a corporate customer, that structure offers a way to accept stablecoins without holding digital assets or changing how money ultimately arrives.

The setup is intended to let large companies accept digital payments without building their own blockchain systems. It also means customers can choose stablecoins at checkout while merchants still receive payment in regular currency — a division of labor that keeps each side working within its existing systems.

What the Companies Are Saying

Debopama Sen, Citi's head of payments, said the bank wants payment infrastructure that works across both traditional and digital systems. She described the goal as making payments “seamless” and “interoperable.”

Alec Lovett, Coinbase's head of infrastructure product, said the partnership gives businesses a fast and compliant link between fiat and stablecoins, allowing users to switch between the two systems without juggling separate payment stacks.

Brett Tejpaul, head of Coinbase Institutional, said the deal connects Coinbase customers with bank-grade fiat infrastructure. He added that Citi clients can now pay with stablecoins without building their own crypto systems.

Coinbase CEO Brian Armstrong commented on the broader partnership when it first launched last year, saying stablecoins are becoming standard tools for updating the global financial system. Taken together, the statements cast stablecoins as payments infrastructure rather than a trading-only product.

Rollout Plans and Parallel Initiatives

The new services will launch first in the United States, and both companies said more institutional payment features are expected in the coming months. That sequence gives businesses a concrete set of checkpoints to watch: the initial US availability, followed by whatever additional institutional payment capabilities the two companies announce next.

Citi is also developing its own tokenized payment system outside this partnership. The bank has already rolled out blockchain-based token services in Japan and the United Arab Emirates. Citi has likewise updated its 12-month price targets for Bitcoin and Ethereum, a move that reflects its ongoing focus on digital asset markets alongside its payments work. The parallel tracks — a shared payments stack built with Coinbase alongside an in-house tokenization effort — reflect the bank's multi-route approach to digital-asset payments.

The expanded partnership keeps both companies focused on linking regulated banking rails with stablecoin infrastructure. For now, the United States remains the starting point before any wider rollout.
