Crypto-asset service providers across the European Union faced stricter enforcement of the Markets in Crypto-Assets regulation on Wednesday as national grace periods for unlicensed operators began expiring. The European Securities and Markets Authority has urged consistent application across member states.

MiCA took initial effect in 2024, with stablecoin provisions applying from mid-2024 and broader rules for exchanges and custodians phased in through 2025. France and Germany had set transitional windows allowing existing firms to continue operating while seeking authorisation, with many of those windows closing around mid-2026.

The European Securities and Markets Authority has repeatedly warned that firms without a MiCA licence must cease offering regulated services once national transition periods end. Exchanges including Binance, Coinbase and Kraken have pursued or secured authorisations in member states such as Ireland, the Netherlands and France to maintain access to the single market.

Market participants reported the deadline added pressure to euro-denominated stablecoins, where issuers must hold reserves and obtain e-money authorisation. Analysts tracking digital assets noted that Tether's USDT has faced delistings on EU-regulated venues, while compliant tokens from Circle and others have gained ground.

A spokesperson for the European Securities and Markets Authority said the regime aimed to protect investors and ensure a level playing field. Supervisory convergence among national regulators remained a priority as enforcement intensified, the spokesperson added.
