Coinbase announced on September 28, 2026 an expanded collaboration with Citi to bring banking and stablecoin payment capabilities to businesses and institutional clients, combining Coinbase’s digital-asset payments infrastructure with Citi’s regulated banking rails.
Coinbase Virtual Accounts also pay 3.75% annual yield on USDC balances, a feature arriving while the GENIUS Act’s implementing regulations remain under a notice-and-comment period following Treasury’s August 2026 proposed rulemaking. Whether that yield structure survives finalized rules governing stablecoin products once the law takes effect in January 2027 remains an open question.
Debopama Sen, Citi’s Head of Payments, Services, said the bank’s goal is to build next-generation payments infrastructure connecting traditional and digital payment networks. Brett Tejpaul, Head of Coinbase Institutional, said the partnership helps realize the full potential of stablecoins for faster, cheaper cross-border payments.
Coinbase also highlighted the expanded collaboration through its official X account:
The latest development moves the companies’ earlier collaboration, first disclosed October 27, 2025, from exploration toward specific products.
What Coinbase Virtual Accounts Do
The first part centers on Coinbase Virtual Accounts, which use Citi’s Virtual Account Wallet, part of its Banking-as-a-Service capabilities, according to Coinbase’s announcement. The accounts give businesses bank-account-like functionality, with incoming fiat automatically converted into stablecoins, a capability Citi describes as an industry first.
| Capability | How It Works |
| Coinbase Virtual Accounts | Provides bank-account-like fiat functionality, plus 3.75% USDC yield |
| Citi Virtual Account Wallet | Supplies regulated banking infrastructure |
| Incoming fiat | Automatically converted into stablecoins |
| Coinbase payments infrastructure | Connects fiat and digital assets |

For businesses building payment products on Coinbase, the structure reduces the need to establish separate banking and digital-asset systems simply to move between fiat and stablecoins.
How Citi Merchants Accept Stablecoins Without Holding Them
The second part works in the opposite direction. Citi’s institutional clients can accept stablecoin payments through Spring by Citi, its merchant-acquiring platform. Customers pay in stablecoins while the merchant receives fiat, since Coinbase handles conversion and Citi settles as bank of record, meaning merchants don’t need their own stablecoin custody.
A Partnership Nearly a Year in the Making
The latest announcement extends the October 2025 collaboration, initially focused on fiat pay-ins and pay-outs for Coinbase’s on- and off-ramps. Citi brings global reach across more than 180 countries, a scale worth understanding alongside the reserve mechanics covered in USDC’s no-hype breakdown.
The Institutional Infrastructure Behind the Deal
Citi’s contribution extends beyond conventional rails. Its 24/7 USD Clearing solution serves more than 300 bank clients globally, and Citi Token Services processes around $1 billion in transactions. Citi has also completed live transactions on Swift’s blockchain ledger with First Abu Dhabi Bank and OCBC, and announced the same week that Token Services is expanding into Japan and the UAE, now live across seven jurisdictions.
| Citi Digital Payment Infrastructure | Reported Scale |
| 24/7 USD Clearing | 300+ bank clients |
| Citi Token Services transaction volume | ~$1B |
| Citi Token Services jurisdictions live | 7 |
| Global reach | 180+ countries/jurisdictions |

This makes the Coinbase collaboration part of a broader Citi effort to connect blockchain-based money movement with its institutional network, comparable to the multi-rail infrastructure covered in 9 best crypto lending platforms in 2026.
Two Different Paths Between Fiat and Stablecoins
The collaboration creates two paths between traditional money and stablecoins: a business receiving fiat can convert it automatically into stablecoins, while a customer paying a Citi merchant in stablecoins triggers conversion so the merchant receives fiat without holding stablecoins directly.
Reaching an Enterprise Market of 150 Million Stablecoin Holders
Coinbase said its infrastructure now reaches an enterprise merchant market representing more than 150 million stablecoin holders worldwide, the broader potential market rather than confirmed users. The more significant development is reduced operational complexity for both sides of the transaction.
What Comes Next for the U.S. Rollout
The new capabilities are launching first in the United States, with more expected in the coming months. Regulatory requirements will remain relevant as the products expand, particularly the still-pending GENIUS Act implementing rules that could affect the Virtual Account yield feature specifically.
What this means for you: Coinbase and Citi are building a two-way connection between traditional banking and stablecoin payments. Businesses can use Citi-powered virtual accounts, earn yield on USDC balances, and automatically convert incoming fiat into stablecoins, while eligible Citi merchants can accept stablecoin payments through Coinbase infrastructure and receive fiat settlement.
The broader significance is the integration of stablecoin functionality into an established institutional banking and payments network, though the yield feature’s long-term durability depends on how federal regulators finalize the GENIUS Act’s interest and yield restrictions.
