The European Securities and Markets Authority (ESMA) has issued a response demanding six changes to the Markets in Crypto-Assets Regulation (MiCA), the European Union's framework governing crypto-asset issuance and service provision across the bloc.

The response, surfaced in reporting by CryptoTicker, signals that Europe's top securities regulator continues to refine the operational and supervisory architecture of MiCA rather than treating the framework as settled once its core provisions entered into application.

At this stage, the specific text of the six demanded changes has not been published in full by the outlet carrying the story. What can be verified from the headline and initial reporting is the count and character of the intervention: six distinct amendments or revisions sought by ESMA in relation to the regulation.

This is not the first time ESMA has moved to adjust the MiCA framework. The regulator has previously issued successive tranches of implementing guidance covering areas such as suitability assessment, conflicts of interest, and the classification of crypto-assets as financial instruments. Each intervention has clarified how the regulation should operate in practice for the authorized crypto-asset service providers (CASPs) that now fall under national competent authorities' supervision.

For firms holding or seeking MiCA licenses, any formal demand for changes to the regulation carries operational weight. Amendments could affect compliance obligations, authorization procedures, or the boundary between crypto-assets regulated under MiCA and those treated as traditional financial instruments under MiFID II. Compliance teams across major venues and issuers — including entities that have pursued CASP registration in jurisdictions such as France, the Netherlands, and Malta — will need to track the outcome before finalizing internal policy revisions.

The demand also arrives at a moment when MiCA's stablecoin provisions, Titles III and IV, have already taken effect, while the broader CASP licensing regime became applicable across member states in December 2024. Any subsequent amendments would therefore apply to a market already in the process of migrating from national regimes, such as Germany's BaFin licensing under the Banking Act, into the passported EU framework.

ESMA's institutional position matters here. As the coordinator of EU securities regulation, its calls for legislative change feed into the European Commission's review process and the work of the European Parliament and Council, who alone can amend the underlying regulation. Implementing measures, by contrast, rest with the Commission on ESMA's technical advice.

The market-structure consequence is straightforward. If the six changes progress, they would add a second layer of adjustment for firms that have just completed initial authorization, potentially reopening questions around grandfathering timelines, third-country firm access, and the scope of activities a single license covers.

Mempool Brief could not independently verify the contents of the six amendments from the available report. The full ESMA response, once published or confirmed, will determine whether the changes target supervisory convergence, consumer protection thresholds, or technical definitions within the regulation.

Market participants and legal teams should watch for the formal publication of ESMA's response and any Commission response deadlines, which will set the timeline for when — and whether — the European legislature moves to amend MiCA.
