MiCA Enforcement Begins: Unauthorized Crypto Firms Face Penalties

The EU's MiCA regulation transition has ended, marking a new enforcement phase for crypto rules. Crypto-asset service providers that didn't obtain authorization can no longer serve clients in the European Union, putting them at risk of enforcement action and penalties.

Industry lawyers and executives note that compliance costs can be substantial, often reaching hundreds of thousands of euros. However, operating without authorization carries higher regulatory and financial risks.

National competent authorities (NCAs) conduct authorization and day-to-day supervision, while ESMA coordinates supervision across member states and maintains a public register of authorized providers. The EBA directly oversees significant stablecoin issuers.
