Europe’s Central Bank Says Stablecoins Could Hit Banks Where It Hurts Most

The European Central Bank’s warning is conditional: if stablecoin use grows, commercial banks could lose retail deposits that fund loans and anchor customer relationships.

The ECB’s proposed answer is a digital euro built to keep banks inside the payment loop.

Retail deposits are the pressure point.

ECB Executive Board member Piero Cipollone delivered the message Friday at the annual meeting of Italy’s cooperative-bank federation in Rome.

In his official speech, Cipollone described two pressures already reshaping banking. Mobile-payment platforms can take fees and transaction data away from banks, while wider stablecoin use could eventually take retail deposits as well.

He gave no estimate, percentage or timetable, and he did not report a current wave of deposits moving into USDT or USDC. His focus was the funding risk that would emerge if consumers begin holding and spending meaningful balances outside commercial-bank accounts.

The audience made the warning especially pointed. Italy’s cooperative banks depend on local deposits and customer relationships, and Cipollone argued that smaller banks face the greatest pressure when payment activity moves to outside platforms.

His pitch was designed for those lenders. The digital euro would run through banks, preserve their role in payments and give them a common European rail while payment data and deposit funding continue to support local credit decisions.

Together we will strengthen trust in money and the banking system, says Executive Board member Piero Cipollone in a @FedercasseBCC lecture.

A retail deposit is money a household or business leaves with a commercial bank. On the bank’s balance sheet, it is a liability to the customer and a relatively stable source of funding.

When a customer buys a stablecoin, the money does not evaporate. It moves.

The payment can leave the customer’s bank, pass to the issuer or its partners, and end up in a reserve mix that may include bank deposits, short-term government debt or other permitted assets. The originating bank can lose the retail customer balance even if part of the reserve remains somewhere else in the banking system.

That changes who controls the relationship, the payment data and the funding.

Some reserves may remain in the banking system or move into government securities. The institution that loses the original customer balance still gives up stable funding and direct control of that relationship.

For cooperative and regional banks, that threat lands close to the business model. Their deposits and local customer knowledge help support lending to households and smaller companies that cannot issue bonds whenever they need cash.

Payments are the front door to the deposit account.

Cipollone said mobile payments already exceed one in 10 point-of-sale transactions in Ireland, the Netherlands and Finland. Banks often pay higher fees when customers use those services and may receive less information about the purchase.

The ECB’s larger concern is European dependence on outside payment infrastructure. According to the speech, two-thirds of euro-area card payments are processed through non-European schemes.

Thirteen of the euro area’s 21 countries have no national card scheme, and more than half have no domestic solution for e-commerce payments.

If Europeans adopt dollar-pegged stablecoins at scale, payment rails, customer balances and even the unit of account could shift toward private foreign issuers.

That is why the ECB presents the digital euro as a payments-sovereignty project.

Decrypt framed the warning as a three-part squeeze on banks: mobile platforms take fees, weaken access to transaction data and, if stablecoin use grows, could pull away deposits. The report also identified the tension in the ECB’s answer, because a public digital wallet could compete with bank accounts too.

The ECB says its design limits that risk through zero interest, holding caps and bank-based distribution. Commercial banks would retain the customer relationship and transaction records while the Eurosystem supplied the settlement asset and shared infrastructure.

Deposits fund credit, so the stakes go beyond payment branding. The design is intended to preserve bank funding and distribution while giving consumers a public digital payment instrument that can work across the euro area.

The digital euro is being built with deposit guardrails.

Under the current plan, customers would access digital euros through their bank and could use the bank’s existing app. Banks would keep the customer-facing relationship while the Eurosystem supplied the public settlement asset and common payment infrastructure.

The digital euro would pay no interest. Holding limits would cap how much a person could store directly in it.

Linking the wallet to a current account would let users make digital-euro payments without prefunding a large balance.

Those features are designed to make the digital euro useful for payments without turning it into a savings product.

Cipollone also said the Eurosystem would see encrypted identifiers rather than the identities of the payer and payee. Banks would retain the information needed for anti-money-laundering checks, risk analysis and the customer relationship.

The proposal lets the ECB offer digital public money while commercial banks keep distribution, transaction records and interchange fees.

Europe has moved the project forward, but it has not approved issuance.

The European Parliament voted 416-169, with 22 abstentions, on July 9 to open negotiations on the digital-euro legislation.

That vote established Parliament’s negotiating position. It did not authorize a digital euro or place one in the hands of the public.

Parliament’s position calls for online and offline payments, privacy safeguards, free basic services and a cap on individual holdings. It would generally require businesses that already accept digital payments to accept the digital euro, while carving out exceptions for certain small operators.

The mandate would also let banks and payment providers from EU countries outside the euro area distribute the currency. Negotiators still have to reconcile that position with the Council before the law can be finalized.

Five days later, the ECB selected 36 payment-service providers from more than 50 applicants for a 12-month pilot scheduled to begin in the second half of 2027. The group includes banks and non-bank providers across a range of business models, sizes and euro-area markets.

The controlled test will run at the ECB and 19 national central banks. The program remains closed, and its beta digital euro will have no legal-tender status.

Central-bank staff, selected merchants, banks and non-bank payment providers will test person-to-person, in-store, e-commerce and offline payments. The work will measure technical readiness and help shape the operating rules before any launch decision.

A 2029 issuance remains conditional on lawmakers completing the legislation by the end of 2026.

The stablecoin fight is becoming a fight over bank funding.

Crypto companies often describe stablecoins as faster dollars. Central banks see a second ledger forming outside the deposit system they supervise.

Once meaningful balances live on that ledger, the argument is no longer limited to payment speed. It reaches lending, monetary control, customer data and which currency dominates digital commerce.

The ECB wants Europeans to gain a digital payment option without giving private dollar issuers or foreign card networks control of the entire route. It also wants commercial banks to distribute that option instead of being bypassed by it.

There is tension in that design. Banks will have to spend money adapting their systems, and a risk-free public payment asset will compete for attention even with caps and no interest.

The ECB’s position is still clear. Private stablecoins can grow into a deposit problem; the digital euro is supposed to modernize payments without creating the same one.

The next test is whether Europeans see enough value to use it—and whether the guardrails are tight enough to keep banks on board.
