Crypto Rules, Round Two: Paris Regulator Asks Brussels to Tweak MiCA

The European Securities and Markets Authority (ESMA), the Paris-based watchman for financial markets across the European Union, is seeking adjustments to the bloc’s landmark Markets in Crypto-Assets (MiCA) framework.

While the request arrives as national supervisors begin enforcing the framework, it highlights a classic institutional reality: once a massive legislative text transitions from political bargaining to daily oversight, the officials charged with running it often find where the original drafting left loose ends. MiCA was designed to establish a single regulatory regime for digital tokens, stablecoins, and crypto platforms across all 27 member states. ESMA is now signalling that parts of the rulebook require refinement to keep pace with market practices.

For anyone using crypto platforms or holding digital assets in Europe, MiCA dictates which companies can legally operate, how user funds must be safeguarded, and what risks platforms must disclose. If enforcement bodies spot ambiguities in the law, retail investors face the risk of inconsistent protection across different member states. Conversely, if unclear text creates administrative confusion, legitimate European firms face unexpected compliance hurdles. Refining the rules early is meant to ensure consumer protection works on the ground rather than just on paper.

In the Brussels ecosystem, watching an administrative agency ask for statutory tweaks to a freshly minted law is a well-known procedural dance. EU legislation is negotiated through intense bargaining between the European Commission, the European Parliament, and member states in the Council. The resulting texts are often masterclasses in political compromise—and operational complexity.

ESMA, which coordinates national market regulators from Paris, must actually enforce these political agreements. When an agency asks for adjustments, it is effectively handing Brussels a reality check, politely reminding policy makers that high-level diplomatic deals eventually have to survive contact with real-world financial software.

ESMA’s recommendations go to the European Commission, the EU’s executive body, which holds the exclusive right to draft amendments to existing legislation. Should the Commission agree to reopen the file, any proposed revisions will need to go through the full legislative process, requiring approval from both the European Parliament and member state ministers in the Council. Until any new text is drafted and passed, ESMA will rely on issuing technical guidelines to ensure national regulators interpret the existing rules as uniformly as possible.
