European Union finance ministers gathered in Nicosia, Cyprus this week for a two-day informal session of the Economic and Financial Affairs Council (ECOFIN) and made one thing clear: they aren't loosening the rules for euro-denominated stablecoins. The ministers sided with the European Central Bank, rejecting proposals to ease liquidity requirements for stablecoin issuers or grant them access to ECB funding facilities.
Why the ECB pushed back
ECB President Christine Lagarde had warned ahead of the meeting that easing the rules could trigger deposit outflows from banks, reduce lending capacity, and hinder the transmission of monetary policy. Her concerns fall into two buckets: bank funding risk — stablecoins pulling deposits out of the banking system — and monetary policy risk, where stablecoins effectively bypass the banking system, weakening the ECB's ability to steer the economy.
The ECB's own scenario modeling from November 2025 concluded that a $2 trillion stablecoin market would transmit U.S. financial stress directly into European banks. With nearly 98% of stablecoin supply currently pegged to the dollar, that risk is anything but hypothetical. Europeans conduct 38% of global stablecoin transactions, yet euro-denominated tokens make up just 0.3% of total stablecoin supply.
Bruegel's proposal — and its quiet burial
The Brussels-based Bruegel think tank had floated two ideas ahead of the Nicosia meeting: ease liquidity requirements for euro stablecoin issuers, and give those same issuers access to the ECB's backstop financing. Central bankers in Nicosia rejected both. No room for compromise on either front, according to officials who attended the closed-door sessions.
The U.S. has already moved in the opposite direction. The GENIUS Act, enacted in July 2025, created a federal framework requiring payment stablecoins to be backed 1:1 with dollar-denominated assets. That law effectively extends dollar dominance into digital payments. Lagarde noted that dollar stablecoins holding U.S. Treasuries as reserves make their holders indirect investors in American government debt — a dynamic she'd rather not see replicated with euro stablecoins.
Lagarde's alternative: tokenized central bank money
Rather than embrace privately issued euro stablecoins, Lagarde is pushing for tokenized financial infrastructure anchored in central bank money. That means projects like the Eurosystem's Pontes wholesale settlement system, and a digital euro targeted for launch by 2029. Her vision: a public-sector digital currency that keeps settlement in the central bank's hands, not in the balance sheets of private stablecoin issuers.
But not everyone at the ECB agrees. Bundesbank President Joachim Nagel backed euro stablecoins in February, putting him at odds with Lagarde. The tension inside the Eurosystem is growing. On one side, the ECB chief sees stablecoins as a threat to banking stability and monetary sovereignty. On the other, Nagel and some market advocates view them as a way to modernize Europe's payment infrastructure and compete with dollar-dominated crypto markets.
For now, the finance ministers have made their choice. The next question is whether Nagel's camp will keep pushing — or whether Lagarde's digital euro timeline can deliver before the market makes its own.
