FollowingHow will Coinbase and Citibank connect fiat and stablecoins?
Coinbase and Citi are expanding their payments partnership with the launch of new infrastructure designed to allow companies to freely flow funds between traditional bank deposits and stablecoins. This architecture can achieve seamless integration without the need for companies to establish a separate system for each currency. Specifically, Coinbase will use Citi's Virtual Account Wallet to empower Coinbase virtual accounts, providing corporate customers with bank account-like functions for receiving, holding and paying fiat currencies. Subsequently, the incoming fiat currency can be automatically converted into stablecoins through Coinbase's payment infrastructure.
This mechanism also supports reverse operations. Customers of Citi Institutions can accept stablecoin payments through "Spring by Citi", Citi's merchant acquiring and payment acceptance platform. During this process, Coinbase provides digital asset payment channels and converts stablecoins into fiat currencies, while Citi serves as the bank of record for settlement. The service was first launched in the United States, and other functions are expected to be launched in the future. This structural design allows merchants to provide stablecoin payment options without having to directly hold or manage digital assets.
This expansion builds on the cooperation announced by the two parties in October 2025, when Citi and Coinbase began exploring fiat encryption channels, withdrawal channels, and stablecoin payment infrastructure for institutional customers.
Why are stablecoins being more deeply integrated into commercial payments?
这笔交易使 Coinbase 进一步深入到连接银行、金融科技公司和企业支付系统的底层基础设施中。此举紧随一系列旨在将稳定币应用从加密货币交易拓展至运营金融领域的合作伙伴关系之后。本月早些时候，Coinbase 与 Moov 合作，将稳定币基础设施引入超过 1,000 家美国社区银行和信用合作社，涵盖支付接受、结算和实时资金注入等功能。
Coinbase 还致力于拓展国际支付流。其与 MassPay 的合作在覆盖 180 个国家的网络中增加了基于稳定币的付款功能；而此前与 Nium 的整合则将 USDC 结算接入更广泛的跨境支付平台。与此同时，花旗正从银行业的角度切入同一市场。花旗支付业务负责人 Debopama Sen 表示，该行希望构建跨越传统和数字支付工具的互操作性基础设施，而非迫使客户在独立系统间做出选择。
Sen 指出：“我们的目标是构建下一代支付基础设施——它是无缝的、可互操作的，并能在传统和数字支付工具及网络上运行。”
投资者启示
Coinbase 与花旗的模式降低了企业采用稳定币的最大障碍之一：企业可以使用区块链支付通道，同时继续通过熟悉的银行基础设施接收和管理法币。
花旗为 Coinbase 的支付业务带来了什么？
对于 Coinbase 而言，与花旗的合作为其支付业务增添了受监管的银行基础设施。Coinbase 目前已处理托管、稳定币转换和区块链结算业务，而花旗的虚拟账户钱包嵌入在其“银行即服务”（BaaS）产品中，允许 Coinbase 提供虚拟法币账户，而无需复制底层的银行基础设施。随后，Coinbase 可以处理法币与数字资产之间的转换层。
对花旗来说，此次合作提供了一种向企业客户提供稳定币接受能力的方式，而无需银行内部构建加密支付栈的每一个元素。花旗此前已在尝试稳定币之外的代币化结算。近期报道显示，花旗与星展银行（DBS）完成了新加坡与美国之间的周末代币化支付，利用代币化银行存款和 Swift 基础设施在几分钟内完成结算。这使花旗接触到了两种竞争性的全天候数字支付方法：代币化的商业银行货币和外部分发的稳定币。
稳定币支付能否成为 Coinbase 的核心业务？
与花旗的协议加强了 Coinbase 推动支付基础设施在其业务中占比更大的努力，使其超越交易所交易领域。Coinbase 推出了一个更广泛的支付平台，专为企业和开发者设计，通过 API 提供稳定币接受、托管、钱包、法币转换和财库管理功能。此后，该公司又在银行、汇款提供商和支付公司之间建立了合作伙伴关系。
Coinbase 与 Circle 的关系在经济上依然至关重要。Circle 于今年 8 月续签了与 Coinbase 的长期商业协议，保留了 Coinbase 在 USDC 分销中的角色及其附带的稳定币储备收入经济利益。
投资者启示
与花旗的合作将 Coinbase 进一步延伸至企业支付领域，那里的收入可能来自基础设施和交易流，而非仅依赖加密货币交易活动。
更大的考验在于，企业客户是否频繁使用稳定币，从而使这些合作超越基础设施公告层面。Coinbase 和花旗正在消除大部分技术摩擦，但最终的采用率将取决于企业是否认为更快的结算速度、跨境转账和持续支付可用性足以改变现有的财库和支付工作流程。
