ECB Warns Euro Stablecoins Could Threaten EU Banking System

The European Central Bank (ECB) has warned EU finance ministers that the rapid expansion of euro stablecoins could create major risks for the European banking sector and weaken the effectiveness of monetary policy. The concerns were raised during recent Eurogroup and Ecofin meetings after Brussels-based think tank Bruegel proposed easing liquidity rules for stablecoin issuers and allowing them potential access to central bank funding.

According to ECB officials, the growing adoption of euro-backed stablecoins may encourage consumers to move savings out of traditional bank deposits and into digital assets. This migration of deposits could reduce the lending capacity of commercial banks across the eurozone, making credit conditions tighter for businesses and households. The ECB believes this issue could intensify as stablecoin usage becomes more mainstream within the European financial system.

The central bank also warned that widespread use of private digital currencies may reduce the impact of ECB interest rate decisions. Monetary policy transmission relies heavily on traditional banking activity, especially deposit-based lending. If more capital shifts into stablecoins, the ECB could face greater difficulty influencing borrowing costs and economic activity through interest rate adjustments.

The debate comes as European regulators face growing pressure from the dominance of dollar-backed stablecoins in global crypto markets. Bruegel argued that strict regulations under the Markets in Crypto-Assets (MiCA) framework have limited the competitiveness of European stablecoin issuers. The think tank described the trend as “digital dollarisation,” warning that US dollar stablecoins could further strengthen the dollar’s influence in international finance.

ECB President Christine Lagarde continues to promote the digital euro as a strategic solution for Europe’s financial infrastructure. However, private-sector momentum remains strong, with several European banks reportedly preparing to launch MiCAR-compliant euro stablecoins in 2026. The ongoing clash between financial stability concerns and the need to compete with dollar-backed crypto assets is expected to shape the future of European crypto regulation and digital finance policy.
