ESMA Calls for Ban on Storing Non-Compliant Stablecoins in EU Crypto Vaults
The European Securities and Markets Authority urges a firm stop to holding unauthorized tokens as data shows USDT usage pulling back across the bloc.

What happened
The European Securities and Markets Authority (ESMA) has asked EU regulators to stop licensed crypto firms from offering custody services for non-compliant stablecoins. The request follows market data showing a clear retreat in the presence of USDT (Tether), the world's largest stablecoin, within the European market. Under the bloc's regulatory framework for digital assets, stablecoins—tokens designed to maintain a steady value by pegging to traditional currencies—must satisfy strict operational and reserve standards to operate legally in the European Union.
Why it matters
For everyday crypto traders, this recommendation narrows the legal room for unapproved digital tokens. If European regulators adopt ESMA's stance, authorized exchanges and digital wallet providers will no longer be allowed to store non-compliant tokens for clients. Investors holding assets like USDT on EU-regulated platforms may face a choice between swapping their holdings into fully compliant alternatives or moving them off European exchanges. The policy aims to protect market stability and investor funds, though it inevitably limits access to certain high-volume global tokens.
The Brussels angle
ESMA, the Paris-based agency tasked with keeping EU financial markets orderly, is tackling a familiar institutional grey zone. While selling unauthorized tokens to retail customers is restricted, keeping those same tokens in client vaults has remained legally ambiguous. The watchdog's request is an effort to close that backdoor. In true Brussels fashion, regulators want to ensure that financial assets barred from entering through the front door of public sales cannot simply sneak around back to rest in institutional custody.
What happens next
The push puts the spotlight on national regulators and the European Commission to clarify whether custody rules will be tightened through formal technical standards. Licensed crypto custody providers operating across the EU will now need to review their asset portfolios and prepare for potential deadlines to phase out support for non-compliant stablecoin storage.
