European Central Bank Executive Board member Isabel Schnabel used a Seoul speech on Monday to sharpen Europe’s warning on stablecoins, arguing that central banks should answer private digital money with tougher regulation and their own digital currencies. Her concern was not that stablecoins are large enough today to replace banks, but that they are growing fast enough to test financial stability, monetary policy transmission and the international monetary order. The warning is about momentum before scale, because the market is already approaching $300 billion, with USDT and USDC representing about 90% of outstanding supply.
Digital euro becomes part of the policy response
Schnabel framed stablecoins as instruments with familiar financial vulnerabilities wrapped in new infrastructure. They can face run risk, she said, because of liquidity mismatches and potential doubts over the quality of backing assets. If confidence in reserves weakens, redemption pressure could accelerate quickly, turning what looks like a payment innovation into a stress channel. The core fear is a private money run migrating onchain, especially if users begin treating stablecoins as cash-like instruments while relying on reserves that may not behave like central bank money under pressure.
The geopolitical layer makes the debate even more awkward for Europe. Schnabel warned that rising stablecoin use could further entrench the dollar’s global dominance, since almost all tokens in circulation are dollar-denominated and other currencies remain marginal. That could amplify the international transmission of U.S. monetary policy while leaving the euro with a limited role in digital settlement. Europe’s concern is not only crypto risk, but monetary dependence, which explains why the digital euro is being presented as a way to preserve the anchoring role of central bank money.
Still, Schnabel did not call for rejecting innovation outright. Her argument was that stablecoins should develop within frameworks that preserve stability, monetary control and trust in money. The contrast with the United States is striking, with Treasury Secretary Scott Bessent again saying the current administration would not allow a CBDC while urging Congress to pass the Clarity Act. The next test is whether Europe can regulate without freezing adoption, as the digital euro remains in technical preparation and the ECB aims to be ready for possible initial issuance by 2029 if legislation is adopted in 2026 under active legislative uncertainty ahead.
