ECB's Cipollone warns stablecoins threaten retail deposits, forcing banks to replace cheap funding with wholesale borrowing. Digital euro pilot set for 2027.
Piero Cipollone, a member of the European Central Bank's executive board, warned Friday that rising stablecoin use threatens to pull retail deposits out of commercial banks. Speaking at a Federation of Italian Cooperative Credit Banks gathering in Rome on July 17, he said the trend forces lenders to replace cheap deposit funding with more expensive wholesale borrowing. That would push up lending rates across the eurozone economy.
Cipollone framed the deposit risk as the latest pressure point in a longer migration away from traditional banking. Mobile payments already cover more than 10% of point-of-sale transactions in Ireland, the Netherlands, and Finland, he noted. Banks collect higher fees on mobile payments than on debit card swipes. They lose access to the transaction data that comes with card networks.
"If the use of stablecoins increases in the future, the banks will also lose retail deposits," Cipollone said.
Smaller banks are most exposed. They depend on customer deposits to fund local loans. If those deposits shift into stablecoins held in digital wallets, lenders would need to tap wholesale funding markets at higher rates, Cipollone argued. That dynamic would feed through to borrowing costs for households and businesses.
The ECB has been pushing its digital euro project as the alternative. The proposed central bank digital currency would not pay interest and would cap the amount any individual could hold. Those features are designed to prevent mass withdrawals. Banks would still distribute the digital euro to customers rather than the ECB dealing directly with the public.
"The digital euro would both preserve the role of public money and ensure banks remain involved in the payments ecosystem while continuing to meet their customers' needs," Cipollone said.
The ECB has selected 36 payment service providers for a 12-month pilot involving 19 national central banks. The beta pilot is scheduled for the second half of 2027. The European Parliament has voted to begin formal legislative work. The ECB does not expect a full launch before 2029.
Cipollone's warning echoes one from board member Isabel Schnabel, who said in June that stablecoins pose risks to financial stability and monetary sovereignty. She compared their emergence to money-market funds that pulled deposits from banks in the 1970s.
Stablecoins are cryptocurrencies pegged to fiat currencies, mostly the U.S. dollar. Tether's USDT and Circle's USDC dominate the market. Both are issued from outside the EU. The EU's Markets in Crypto-Assets regulation covers euro-denominated stablecoins. It leaves dollar-pegged tokens mostly outside direct oversight. Euro stablecoin issuers must keep at least 30% of reserves in bank deposits under MiCA. That figure rises to 60% for issuers classed as "significant." Those requirements could trigger sudden bank outflows during mass redemptions, the ECB has said.
Circle has met MiCA compliance for USDC and EURC. They are the only top-ten stablecoins by market cap to satisfy the new rules. The ECB has said regulation alone cannot solve the monetary sovereignty and deposit-migration problems.
The ECB is also working on Project Pontes, which aims to settle tokenized assets using central bank money. Project Appia, a public-private marketplace for tokenized finance, is also in development. Both projects signal the bank's intent to keep commercial banks and central bank money at the center of Europe's digital financial system.
About two-thirds of euro area card transactions run through non-European networks. Thirteen of 21 eurozone countries lack a domestic card facility, the ECB said. That dependence on foreign payment infrastructure is part of the motivation for a European-controlled digital payment system.
