ECB warns stablecoin growth could pressure bank deposits as digital euro plans advance

The European Central Bank is drawing a clearer line between stablecoin adoption and the future of bank funding. In a speech in Rome on Friday, ECB Executive Board member Piero Cipollone argued that if stablecoin use expands meaningfully in everyday payments, commercial banks risk losing a larger share of retail deposits alongside payment fees and customer transaction data. The intervention matters because it moves the debate beyond abstract concerns about digital money and places stablecoins inside a core banking-policy question: who controls customer balances, payment relationships and monetary distribution in a more digital financial system.

Cipollone framed the issue in the context of a broader shift away from cash and toward app-based and mobile payment experiences. As those channels gain share, banks are already under pressure from platform intermediaries that sit between customers and the underlying account infrastructure. His argument is that stablecoins could deepen that pressure by creating another settlement and store-of-value layer outside the traditional deposit model. In that framing, the concern is not only competition in payments. It is the possibility that part of the retail money base migrates into tokenized instruments issued and circulated on non-bank rails, reducing a source of stable funding that banks have historically relied on.

That warning sits at the center of the ECB’s case for a digital euro. Rather than presenting a retail central bank digital currency as a replacement for banks, Cipollone emphasized that the design objective is to keep banks embedded in digital payments as distribution partners. The ECB’s message is that public money must remain usable in digital form if it is to continue anchoring trust in the wider monetary system. In practice, that means the institution wants a digital payment instrument that preserves convertibility into central bank money while still allowing banks to manage customer relationships, compliance workflows and front-end service delivery.

The speech also aligns with a more operational phase of the project. On its digital euro pilot page, the ECB says it received applications from more than 50 payment service providers after a March 2026 call for expressions of interest and selected 36 participants for a 12-month pilot due to start in the second half of 2027. The central bank says that work is intended to prepare the technical and operational path for a possible issuance decision in 2029, assuming the underlying regulation is adopted in 2026. That sequence is important: the ECB is no longer discussing only principles, but also vendor readiness, PSP participation and launch mechanics.

For the stablecoin market, the ECB’s language is notable because it treats tokenized cash-like instruments as systemically relevant to bank intermediation, not simply as a crypto niche. Dollar stablecoins already dominate most onchain settlement activity, and their use in exchanges, payments, treasury operations and cross-border transfers has made them part of the infrastructure conversation for major financial institutions. From a European policy perspective, that creates a strategic problem as well as a prudential one. If domestic payment activity increasingly relies on non-European private issuers or foreign-currency stablecoins, the region’s control over money movement, data and monetary transmission weakens at the same time.

That is why the ECB’s position should be read as a two-track policy stance. On one track, officials are signaling that stablecoin growth deserves close scrutiny because of its implications for deposits, payment sovereignty and financial stability. On the other, they are trying to accelerate a state-backed digital alternative without severing banks from the customer interface. The emphasis on cooperative banks in Cipollone’s remarks was part of that balancing act: the digital euro is being sold not as a disintermediation tool, but as infrastructure that could help banks remain relevant as payments migrate toward programmable, tokenized and platform-native forms.

For RWA and onchain finance builders, the takeaway is straightforward. European policymakers increasingly view stablecoins as part of mainstream financial plumbing, which means the regulatory and competitive environment around tokenized money is becoming more consequential for every product that depends on cash settlement onchain. Stablecoins may continue to grow because they solve real distribution and interoperability problems, but the official response in Europe is now becoming more concrete, more institutional and more closely tied to the future architecture of money itself.
