The US Has Chosen Private Stablecoins Over a Digital Dollar, and AI Agents Are Starting to Pay

Three announcements from the past few days show the rails of money being redrawn on three very different fronts at the same time. The US Senate has voted to keep the Federal Reserve out of central bank digital currencies until at least 2030, while keeping the door open for private stablecoins. In Ukraine, Mastercard and the country’s largest bank have completed the first AI agent payment. 

The US Senate Has Blocked the Federal Reserve from Issuing a CBDC

On Monday 22 June, the US Senate passed the 21st Century ROAD to Housing Act in an 85 to 5 vote, with the House approving the package on Tuesday 358 to 32. The bill is now expected to be signed by President Donald Trump. Buried in the housing legislation is a provision amending the Federal Reserve Act so that the Board of Governors and Federal Reserve banks cannot issue or create a central bank digital currency, or any digital asset substantially similar to one, directly or indirectly through any financial institution or intermediary. The prohibition runs through 31 December 2030. Even after that date, the central bank would need explicit Congressional authorisation before pursuing a digital dollar. There is no active US CBDC project to halt. President Trump signed an executive order in January 2025 opposing a digital dollar, and Federal Reserve Chair Kevin Warsh has publicly opposed one too.

The exception is important. The provision does not prohibit any dollar-denominated currency that is open, permissionless and private, and that preserves the privacy protections of US physical currency. In practice, that carves out private stablecoins issued under the GENIUS Act framework, including those from Circle, Tether and any future Permitted Payment Stablecoin Issuer. The US is therefore now sketching the cleanest line of any major jurisdiction between a public central bank digital dollar (rejected) and private digital dollars (encouraged and increasingly regulated). The contrast with elsewhere is striking. The European Central Bank is preparing a digital euro pilot for next year and a full launch in 2029. On 16 June, Reuters reported that China added 26 financial institutions to its e-CNY cross-border platform. Per the Atlantic Council, three countries have launched CBDCs, 41 are in pilot, 33 are in development and 40 are still in the research phase.

Why it matters: This is the clearest statutory signal yet that the US is choosing private, regulated digital dollars over a Federal Reserve issued one. For payment networks, banks and fintechs, the practical takeaway is that the long-term US digital dollar story is now built almost entirely on private stablecoin rails, with the public sector focused on stablecoin oversight rather than CBDC issuance. Expect more capital to flow into compliant stablecoin issuers and the infrastructure around them, and expect this to influence how other jurisdictions calibrate their own CBDC roadmaps.

The Debia angle: Our consistent view is that the future of settlement is interoperability between traditional rails and compliant digital assets, with regulation built into the foundation. The US move locks that thesis into legislation for the world’s reserve currency. The implication for any payments business, including Debia, is that strategy should be designed around regulated stablecoins as a core building block in cross-border commerce, not as an experimental side project, while remaining flexible to operate in markets that take a different path on CBDCs.

Mastercard and PrivatBank Complete Ukraine's First AI Agent Payment

On 23 June, Mastercard and PrivatBank, Ukraine’s largest bank, announced that they had completed the country’s first agentic transaction, executed through Mastercard’s Agent Pay programme. Agentic commerce, where AI agents act on behalf of consumers to shop, manage subscriptions and complete everyday tasks, is the layer Mastercard has been building toward since launching Agent Pay in 2025 and Agent Pay for Machines two weeks ago. The framework integrates AI agents into the payment flow as visible, governed participants, with each transaction authenticated, controlled and traceable. Inga Andreieva, Country Manager for Mastercard in Ukraine and Moldova, described the milestone as setting the foundations of a new era of digital commerce, built on the same trust, transparency and security principles that have guided Mastercard’s work in Ukraine for 30 years.

PrivatBank, for its part, confirmed its technical and operational readiness to support AI-driven transaction models, and the two companies said they will continue exploring use cases for scaling AI-powered commerce within strong controls, resilience and regulatory alignment. The move sits inside a clear pattern. Mastercard’s Agent Pay defines how trusted AI agents participate in payments. Agent Pay for Machines, launched earlier this month, extends the framework to programmatic machine-to-machine transactions running at high frequency, low latency and tiny values. With PrivatBank, Mastercard is now showing that the same agentic framework can land in an incumbent retail bank in an emerging market, not just in the Silicon Valley test environments where most agentic commerce conversations have lived so far.

Why it matters: This is one of the first credible signals that agentic commerce is moving from a category that lives in slide decks and pilots into something that retail banks in real markets can operationally support. Ukraine has long had one of the most digitally engaged consumer payment markets in Europe, and PrivatBank’s scale gives this deployment an unusually broad immediate footprint. Expect more major card networks and incumbent banks across Europe, the Middle East and Asia to follow this template, and expect agentic commerce to gradually become a standard layer on top of card and account rails rather than a separate stack.

The Debia angle: This is exactly the seam where Debia’s view of payment infrastructure is sharpest. AI agents are most valuable when they are added as visible, governed participants on top of compliant payment rails, not when they sit outside them. The Mastercard and PrivatBank model treats AI as a new kind of authorised actor inside existing controls. The lesson for any merchant or payments business is to design the orchestration layer with that future in mind, so that as AI agents start to transact more frequently on behalf of consumers and businesses, the infrastructure underneath behaves predictably, regardless of who or what initiates the transaction.

At Debia, we track these changes because the future of payments will be shaped by speed, trust, interoperability, and smarter financial infrastructure. We do not just process payments. We understand the infrastructure, regulation, technology, and market shifts behind the future of digital commerce, and we build for where the ecosystem is heading next.
