A potential run on stablecoins could force the European Central Bank to reconsider its monetary policy approach, according to Dutch central bank governor Olaf Sleijpen, who warned that dollar-pegged digital tokens are rapidly approaching systemic relevance.

The $300 billion stablecoin market, which has surged over 48% this year following new U.S. regulations under President Trump, now poses direct risks to European financial stability, economic growth, and inflation control that may require ECB intervention.

“If stablecoins in the US increase at the same pace as they have been increasing, they will become systemically relevant at a certain point,” Sleijpen told the Financial Times, noting that instability in these tokens could trigger mass sell-offs of underlying assets, primarily U.S. Treasuries.

While the central bank would likely deploy financial stability tools first, he acknowledged uncertainty over whether rate cuts or increases would follow, stating, “I don’t know in which direction we would be going.“

The explosive growth of dollar-denominated stablecoins has sparked alarm among European institutions, with officials warning that the bloc faces conditions similar to those in emerging markets, where widespread foreign currency use undermines domestic monetary policy.

A senior ECB official warned this summer that dollar stablecoin dominance could hamper European policymakers’ ability to set interest rates or control money supply, while Nobel Prize-winning economist Jean Tirole cautioned that token failures could force governments into multibillion-dollar bailouts.

These concerns intensified after the U.S. enacted the GENIUS Act in July, establishing federal oversight for stablecoin issuers and spurring rapid market expansion.

The European Systemic Risk Board, chaired by ECB President Christine Lagarde, escalated warnings in October by identifying “built-in vulnerabilities” in multi-issuer stablecoin models.

During its 59th General Board meeting, the ESRB endorsed a recommendation to ban structures where EU-regulated issuers hold local reserves while non-EU partners manage identical tokens backed abroad.

They warned that stress-driven redemptions could overwhelm European reserves and expose the bloc to offshore liabilities.
