Main Topic
European banks are increasingly challenged by a sequence of technological and market shifts that reduce their role in everyday payments. Mobile payment apps and non-bank payment providers have already captured fees and transaction data that historically flowed through banks. More recently, privately issued stablecoins—cryptocurrency tokens pegged to fiat currencies and usable entirely outside the traditional banking system—have introduced a new potential threat: the migration of retail deposits away from banks entirely.
Piero Cipollone, a member of the European Central Bank (ECB) executive board, summarized this risk at a banking conference in Rome. He argued that banks lose revenue and valuable customer information when payment activity moves to third-party platforms. That erosion matters because deposit balances are the primary funding source banks use to extend credit. If deposits shrink materially, lending capacity and local credit provision could decline. The impact would be especially acute for smaller cooperative banks and regional lenders that depend on deposit-funded lending and local payment data to underwrite loans.
Stablecoins are usually privately issued tokens that aim to maintain a 1:1 peg with a fiat currency, most commonly the U.S. dollar. They enable users to hold and transfer value in apps or crypto wallets without routing funds through a regulated bank account. While fintechs like PayPal and Stripe still interact with banks behind the scenes, stablecoins can operate largely outside traditional deposit and payment systems. The global market for stablecoins is substantial—around hundreds of billions of dollars—and predominantly dollar-denominated, which underlines both the scale and international orientation of the phenomenon.
The ECB frames the risk as more than theoretical. Mobile payments already constitute a rising share of point-of-sale transactions in several euro-area countries; in places such as Ireland, the Netherlands and Finland, mobile payments exceed one in ten POS transactions. For banks, mobile payments often mean paying higher processing fees and losing granular transaction information. The further adoption of stablecoins could go a step beyond fees and data loss and threaten the actual deposit base banks rely upon for liquidity and lending.
Deposits are not merely passive balances: they are the primary source of loanable funds for many banks. When deposits leave the banking sector, the immediate consequence is a reduction in low-cost funding available to support lending to households and businesses. For small local banks—many of which operate on thin margins and serve tight-knit communities—the loss of deposit-driven lending capacity can become an existential threat rather than a distant accounting problem. In Italy, for example, many cooperative bank branches operate in towns with fewer than 10,000 inhabitants; losing access to payment data and deposits could hollow out their ability to support local customers and underwriting relationships.
To address these risks, the ECB has proposed a public-sector solution: the digital euro. Designed as a government-backed electronic form of central-bank money, the digital euro would be distributed through commercial banks and designated payment providers rather than replacing them. In the ECB’s proposed model, banks would continue to host customer accounts, collect interchange fees, and retain payment data, thereby preserving critical parts of the existing banking business model while offering citizens a digital form of cash.
The ECB has already moved toward operational testing. It named 36 payment service providers, including major banks and fintechs, to participate in a 12-month digital-euro pilot slated to begin in the second half of 2027. This pilot aims to test practical distribution models, user experience, and the interaction between centralized digital cash and commercial banking infrastructures.
Critics warn that a widely available, government-backed digital wallet could itself drain deposits from commercial banks, much like stablecoins might. The ECB’s design attempts to mitigate that risk by incorporating limits: the digital euro would not offer interest, reducing incentives to hold large balances purely for yield, and holding caps would limit how much any individual could store in digital-euro accounts. The ECB’s financial stability assessment indicates that, with these measures, the digital-euro design should not pose a material risk to bank liquidity.
Nevertheless, not everyone is convinced. Observers point out that behavioral responses, competitive dynamics, and unforeseen interactions with other financial innovations could change outcomes. Policymakers must therefore balance competing priorities: protecting the integrity and funding of the banking system, preserving consumer access to safe and efficient payment methods, and ensuring competition and innovation in payments. Legislative processes are underway in the European Union, with formal negotiation steps already initiated and an early timetable targeting agreement by the end of 2026 and potential first issuance around 2029.
In practice, the interaction between stablecoins, incumbent banks, fintechs, and a potential digital euro will hinge on design details, regulatory treatment, and user preferences. The extent to which banks can retain fees, data rights, and customer relationships will influence their ability to compete. At the same time, regulators face trade-offs between restricting novel private instruments that disintermediate banks and enabling innovation that improves payment efficiency for consumers and businesses.
Overall, the ECB’s warnings reflect a credible set of risks: continued migration of payments and balances away from banks could reduce loanable funds and weaken local banking ecosystems. The digital euro is presented as a measured policy response intended to preserve the public utility of central-bank money in a digital age while minimizing disruption to commercial banks. Whether that approach will succeed depends on implementation, user adoption, and how private stablecoin issuers and payment platforms evolve in response.

Looking ahead, several technology and policy areas deserve greater attention. Research into account design and limits for central-bank digital currencies (CBDCs) can refine how to balance usability and financial stability. Improved interoperability standards between bank accounts, payment apps, and digital wallets would reduce friction while allowing regulators to monitor systemic flows. Enhanced data-sharing frameworks—designed to protect privacy while enabling banks to retain useful transaction signals—could help incumbent lenders sustain credit underwriting capabilities.
At the same time, regulators should continue assessing private stablecoins through robust custody, reserve, and transparency standards to limit systemic risk. Experimentation—such as the ECB’s pilot program—will be essential to test real-world impacts and user behavior. Finally, ongoing dialogue among central banks, commercial banks, fintechs, and lawmakers is critical: market design choices will determine whether digital payments enhance competition and convenience without undermining the banking system’s role in credit intermediation.
In short, the shift toward digital payments and tokenized money is reshaping fundamental funding and payments relationships. Careful policy design, technological interoperability, and tailored regulation will determine whether Europe can capture the benefits of innovation while protecting the stability and credit provision that underpin its economy.
