ECB: Stablecoins Threaten Bank Deposits – and the Digital Euro Is the Proposed Defense
European banks have been steadily ceding ground in the payments business. First they lost dominance over how people initiate payments. Now, the European Central Bank (ECB) is warning they could lose something far more critical: customer deposits themselves.
According to ECB Executive Board member Piero Cipollone, stablecoins and other private digital payment instruments could siphon away the core funding base of traditional banks, undermining their role in the financial system. His message, delivered at a banking conference in Rome, was blunt: the digital euro is, in his view, the only structural answer to this mounting threat.
Below is what this shift means, why the ECB is worried, and how the digital euro fits into the picture.

From Cards to Apps: How Banks Lost Control of Payments
For decades, banks sat at the center of the retail payments ecosystem in Europe. Customers used bank-issued cards, banks processed the transactions, and banks earned the fees while retaining ownership of transaction data.
That world is fading.
First came mobile payment apps-many of them developed by fintechs or big tech firms. These apps have inserted themselves between customers and their banks, controlling the user interface, capturing data, and in many cases, taking a share of transaction fees. Banks may still hold the accounts, but they no longer fully control how customers pay.
Cipollone pointed out that even traditional debit cards are losing ground:
– Mobile payments are gaining rapidly.
– In Ireland, the Netherlands, and Finland, mobile payments already account for more than one in ten point-of-sale transactions.
– As consumers tap phones instead of plastic cards, banks often end up paying higher fees to the tech and payment providers that operate these systems.
In other words, banks now pay more to participate in a market they once dominated-and they are no longer the ones owning the customer relationship in day-to-day payments.

The Next Phase: Stablecoins Target Bank Deposits
So far, most of the damage to banks has been about fees and data. Stablecoins, however, threaten something more fundamental: deposits.
Stablecoins are crypto-assets that aim to maintain a stable value, often pegged to a fiat currency like the euro or U.S. dollar. They are widely used for trading, DeFi, and cross-border transfers. But as they become more user-friendly and integrated into mainstream payment systems, they may start functioning as everyday money substitutes.
From the ECB’s perspective, this introduces a three-layer threat to banks:
1. Loss of payment traffic
Payments increasingly happen in closed ecosystems (apps, platforms, or crypto networks), where banks are just back-end service providers or are bypassed altogether.
2. Loss of economic data
Whoever controls the payment interface controls the data: spending patterns, merchant types, user behavior. This data is immensely valuable for credit assessment, product development, and risk management. As payments move to third-party platforms and stablecoin rails, banks lose insight into customers’ financial lives.
3. Loss of deposits
If individuals and businesses start storing value directly in stablecoins rather than in bank accounts, deposits shrink. This is not just a profitability problem; it strikes at the heart of banking. Deposits are the main, low-cost funding source that allows banks to grant loans to households and companies.
The ECB warns that in an extreme scenario, a widespread shift to stablecoins or private digital monies could:
– Weaken banks’ ability to lend to the real economy.
– Make banks more reliant on more expensive or volatile funding sources.
– Increase financial stability risks, especially during stress, if people quickly flee bank deposits for digital alternatives perceived as safer or more convenient.

Why Stablecoins Are Attractive – and Dangerous in Scale
From a user’s perspective, stablecoins offer several advantages:
– Speed: Near-instant transfers, including cross-border.
– Programmability: They can be used in smart contracts and automated payments.
– Interoperability: A single token can move across multiple platforms and services.
– 24/7 availability: Unlike some bank transfers, stablecoin networks don’t close on weekends or holidays.
These features make stablecoins compelling as a modern payment and settlement tool. But the ECB’s concern is not about the technology itself-it is about who controls the instruments that could become widely used as money.
If large platforms, payment providers, or global companies issue or integrate stablecoins at scale, they could become “gatekeepers” of the financial system:
– They could set their own rules for access and fees.
– They might favor certain partners and exclude others.
– Their business models might prioritize profit and data extraction over financial stability and consumer protection.
In such a landscape, banks could be pushed further into the background, reduced to utility providers while value and data concentrate in a few powerful private networks.

The Digital Euro as a “Structural” Solution
Cipollone framed the digital euro as the only structural response capable of addressing these medium- and long-term threats.
The digital euro is envisioned as:
– A form of central bank money available to everyone, not just banks.
– A digital complement to cash, not a replacement.
– A safe, state-backed payment instrument that can be used in stores, online, and potentially for peer-to-peer transfers.
From the ECB’s vantage point, it could help in several ways:
1. Preserving monetary sovereignty
If digital payments continue to shift toward private currencies or foreign-controlled payment networks, Europe risks losing control over its own monetary system. A widely used digital euro would keep the euro at the core of digital payments.
2. Providing a public anchor in a digital world
Just as cash anchors trust in money today, a digital euro would act as a public benchmark for value and safety in the online space, coexisting with private means of payment.
3. Offering an alternative to private stablecoins
If people can hold and transfer digital euros with similar ease and speed as stablecoins-but with central bank backing-there is less incentive to migrate en masse into privately issued tokens.
4. Maintaining the role of banks-under conditions
In most designs discussed, commercial banks and payment service providers would remain the interface between the ECB and end-users. They would handle onboarding, KYC, and customer service, while the central bank manages the core infrastructure. This could preserve a central role for banks in the retail financial system, even as the nature of money evolves.

The Trade-Offs for Banks
For banks, the digital euro is both an opportunity and a challenge.
Opportunities:
– They could offer new digital euro-based services and wallets.
– They could remain central intermediaries in retail payments rather than being disintermediated by big tech or stablecoin issuers.
– Integration with a central bank-backed digital currency could strengthen trust and reduce reliance on non-European platforms.
Concerns:
– If individuals can hold significant amounts of digital euros directly backed by the ECB, they might shift money out of bank accounts, especially in times of stress.
– Deposit outflows could constrain lending and force banks to rely more on wholesale funding, increasing their costs.
– Banks fear the digital euro might accelerate, rather than slow, the erosion of their deposit base-ironically, the very threat the ECB attributes to stablecoins.
To address some of these worries, policymakers are debating design features such as:
– Holding limits on how many digital euros an individual or firm can store.
– Tiered remuneration, where larger digital euro balances might earn lower or even negative interest, discouraging large-scale shifts from bank deposits.
– Intermediated models where banks retain a central role in distribution and user interaction.

What This Means for Users of Stablecoins and Crypto
For people and businesses already using stablecoins, the ECB’s warnings signal that regulation and oversight will tighten further.
Key implications include:
– Stricter rules for issuers: They may face capital, liquidity, and governance requirements closer to those for banks or e-money institutions.
– Closer scrutiny of reserves: Authorities will want to ensure that stablecoins are fully backed and redeemable at par, especially if they start to be used widely for payments rather than just trading.
– Constraints on integration with mainstream finance: As stablecoins plug into traditional payment networks or bank accounts, they’ll likely fall under more comprehensive regulatory regimes.
In the longer term, users may see a clearer division:
– On one side, public money (cash and potentially the digital euro), strongly regulated and backed by the central bank.
– On the other, private digital instruments (stablecoins and other tokens), allowed but more tightly controlled to prevent systemic risks.

Could Stablecoins and the Digital Euro Coexist?
The landscape is unlikely to become a simple “either-or.” Stablecoins and a digital euro can coexist, but likely in specialized roles.
Possible outcomes:
– The digital euro could dominate everyday retail payments in the euro area, especially for domestic transfers and point-of-sale transactions.
– Stablecoins could remain important in global crypto markets, decentralized finance, tokenized assets, and cross-border use cases where central bank money is not easily accessible or interoperable.
– Banks might offer hybrid products, allowing customers to move funds between traditional accounts, digital euros, and regulated stablecoins within a single interface.
The real competition is not only between stablecoins and the digital euro, but between public monetary systems and private, platform-based networks that aspire to play the role money once reserved for states and banks.

How This Shapes the Future of European Banking
The ECB’s warning is part of a larger narrative: the traditional banking model, heavily reliant on deposit-funded lending and dominance over payments, is under pressure from multiple directions:
– Technology firms controlling user interfaces and data.
– Fintechs innovating around speed, convenience, and programmable money.
– Stablecoin issuers and crypto platforms offering alternative rails for value transfer.
For European banks to remain relevant, they will likely need to:
– Invest heavily in digital infrastructure and user experience.
– Embrace regulated digital assets and CBDC integration rather than resisting them outright.
– Reimagine revenue models beyond simple payment fees, focusing more on advisory, lending, and value-added services.
The ECB, for its part, is making clear that it does not intend to stand by while private forms of digital money hollow out the foundations of the banking system. The digital euro is conceived not only as a new payment tool, but as a strategic instrument to ensure that, in the era of crypto and stablecoins, the euro remains at the center of Europe’s financial life.

Bottom Line
– Banks have already lost ground in payments to mobile apps and digital platforms.
– The ECB now fears stablecoins could go further and drain bank deposits, threatening banks’ ability to lend and maintain stability.
– Piero Cipollone argues that a digital euro is the only structural solution to counter this trend, preserve monetary sovereignty, and provide a safe public alternative to private digital money.
– The coming years will determine whether Europe’s response-combining tighter stablecoin regulation with a central bank digital currency-can reshape the digital money ecosystem without breaking the traditional banking model that still underpins the real economy.
