Citi and Coinbase Put Stablecoins Behind Corporate Payments

Citi and Coinbase are expanding their partnership to let businesses move between traditional dollars and stablecoins without having to build or manage separate banking and crypto infrastructure.

The collaboration connects Citi’s regulated banking rails with Coinbase’s stablecoin payment infrastructure in two directions. Coinbase customers will gain bank-account-like virtual accounts that automatically convert incoming fiat into stablecoins, while Citi’s institutional clients will be able to accept stablecoin payments and receive fiat settlement.

The services are launching first in the U.S., according to Coinbase.

Stablecoins Move Into the Background

The most notable part of the arrangement is that businesses do not necessarily need to interact with stablecoins directly.

Coinbase is using Citi’s Virtual Account Wallet to power its Virtual Accounts. The accounts allow businesses to accept, hold and pay fiat while automatically converting incoming funds into stablecoins.

On the other side, Citi’s institutional clients can use Spring by Citi, its merchant-processing and payment acceptance platform, to accept stablecoin payments from customers. Coinbase provides the blockchain payment rails and automatically converts the digital assets into fiat, with Citi settling the funds as the bank of record.

This creates a payment flow in which a customer can pay with a stablecoin while the merchant receives traditional currency, without the merchant needing to hold or manage the digital asset.

For businesses using Coinbase’s Virtual Accounts, the reverse is also possible: fiat can enter through conventional banking infrastructure and be converted into stablecoins without requiring a separate banking and digital-asset setup.

From 2025 Collaboration to Payment Infrastructure

The expanded arrangement builds on a partnership Citi and Coinbase announced in October 2025, when the companies began exploring ways to connect fiat and digital-asset payment infrastructure.

The latest development moves that relationship from exploration toward specific business-facing payment products.

The two companies are effectively dividing the infrastructure: Citi provides regulated banking and settlement capabilities, while Coinbase supplies the stablecoin and blockchain payment rails.

That model reflects a broader shift in how financial institutions are approaching digital assets. Rather than asking corporations to replace existing payment systems with blockchain networks, banks and crypto companies are increasingly putting blockchain infrastructure underneath familiar financial products.

Unlock Blockchain previously reported on Coinbase’s expansion of stablecoin pilots with U.S. banks, as financial institutions began testing stablecoins for payments, custody and trading.

Citi Builds a Parallel Onchain Payments Stack

The Coinbase partnership is also one part of Citi’s wider blockchain strategy.

Earlier this month, Citi and DBS completed a weekend cross-border transfer using tokenized deposits through Swift’s blockchain-based Digital Ledger, settling the transaction between Singapore and the U.S. in minutes rather than through conventional banking windows.

Citi is also participating in a proposed U.S. tokenized deposit network with JPMorgan, Bank of America and Wells Fargo, targeting a 2027 launch. The planned infrastructure is designed to allow tokenized bank deposits to move between participating institutions and support continuous settlement.

The Citi-Coinbase model differs from those bank-led tokenized deposit initiatives.

Here, the digital asset is a privately issued stablecoin, with Coinbase providing the blockchain infrastructure and Citi providing the regulated banking layer. In the tokenized deposit projects, banks are instead exploring blockchain representations of commercial bank money.

The distinction points to two parallel approaches developing within institutional payments: banks are building tokenized versions of their own deposits, while partnerships with crypto infrastructure providers are connecting existing stablecoins to banking networks.

Corporate Payments Become the Testing Ground

Stablecoins have increasingly moved beyond their original role as crypto-market settlement assets.

Unlock Blockchain reported in February that the stablecoin market had surpassed $300 billion, with research pointing to growing use in payments, payroll, remittances and savings. That coveragehighlighted the shift toward stablecoins as financial infrastructure rather than purely trading instruments.

The Citi-Coinbase arrangement puts that trend into a specific corporate payments environment.

For a merchant, the potential use case is straightforward: a customer pays in a stablecoin, Coinbase handles the digital-asset transaction and conversion, and Citi settles the merchant in fiat.

For a Coinbase payments customer, the model works in reverse: traditional dollars enter through Citi’s banking infrastructure and can be converted automatically into stablecoins for digital payments and other uses.

The blockchain layer therefore becomes largely invisible to the business using it.

U.S. Launch Comes First

The two initiatives will initially launch in the United States, with additional capabilities expected to follow.

Citi said the broader goal is to build payments infrastructure that operates across traditional and digital payment instruments and networks.

The expansion comes as major banks and payment companies pursue different forms of blockchain-based money and settlement infrastructure. Citi’s own tokenized deposit projects, bank-led stablecoin initiatives and partnerships with crypto companies are developing alongside efforts from JPMorgan, Visa, Mastercard and other financial institutions.

For Citi and Coinbase, the latest collaboration puts stablecoins inside existing corporate payment flows rather than requiring businesses to adopt a separate crypto payment system.
