The European Securities and Markets Authority (ESMA) will directly supervise only the largest crypto firms operating in the European Union, according to a report by CryptoTicker. The remaining majority of crypto-asset service providers (CASPs) will fall under the oversight of their national competent authorities under the Markets in Crypto-Assets regulation (MiCA).

The report frames the split as a two-tier structure. ESMA takes the firms whose cross-border footprint makes them systemically relevant, while national regulators retain day-to-day supervision of smaller providers. That division mirrors how EU securities markets already operate: ESMA directly supervises a narrow set of critical entities such as credit rating agencies and trade repositories, leaving most issuers and intermediaries to member-state regulators.

What does this mean for crypto firms?

For large CASPs, direct ESMA supervision means a single point of contact for authorization and ongoing compliance across the bloc. That can reduce duplications among national filings but concentrates enforcement risk in one regulator with a pan-European mandate.

Smaller firms will continue to deal with their home-country authority. The operational consequence is procedural: authorization, reporting and inspection timelines will depend on the capacity and posture of each national regulator, which varies across member states.

Why does the threshold matter?

The size criterion determines which firms face the EU-level supervisor. Firms near the threshold must track how the boundary is defined, because crossing it changes the regulator, the reporting chain and potentially the compliance cost base.

The classification also affects supervisory consistency. A regulator supervising only the largest firms can standardize expectations across that cohort, while smaller providers face a patchwork of national approaches.

What comes next?

MiCA's supervisory architecture is still settling into practice across the EU. Firms on both sides of the size threshold will watch how ESMA and national authorities divide enforcement in the first supervision cycles, and whether the two-tier split holds as the market consolidates.
