ESMA Proposes Sweeping MiCA Reforms to Target DeFi and Unregulated Stablecoins

The European Securities and Markets Authority (ESMA) has formally responded to the European Commission’s public consultation on the Markets in Crypto-Assets Regulation (MiCA) ¹. The regulator's recommendations aim to tighten investor protections, expand supervisory powers over offshore firms, and establish a concrete regulatory boundary for decentralized finance (DeFi) and staking ¹.

At the time of writing, the broader digital asset market is trading slightly lower, with $BTC priced at $83,855 and $ETH at $2,694. This regulatory push comes as the European Commission reviews the functioning of the MiCA framework, which was originally implemented in 2024 to harmonize rules for crypto-assets, issuers, and service providers across the European Union ³.

Targeting DeFi and Staking Under a New Regulatory Umbrella

As decentralized protocols and alternative yield mechanisms grow, ESMA is advocating for a significant expansion of MiCA's scope ¹. The regulator has called for the introduction of clear criteria to determine whether a protocol or activity is genuinely decentralized ¹.

For platforms that do not meet these strict decentralization criteria, ESMA proposes creating a new regulated crypto-asset service category specifically for firms that provide users with access to DeFi protocols ¹. Furthermore, the regulator is seeking to bring staking, lending, and borrowing under a proportionate regulatory regime ¹. This would mandate explicit disclosure obligations regarding costs, rewards, collateral arrangements, and potential losses before retail investors can participate ¹.

To resolve ongoing disputes over asset categorization, ESMA has requested the authority to issue binding opinions on token classifications, including hybrid tokens, to ensure uniform treatment across all EU member states ¹.

Crackdown on Influencers, Offshore Firms, and Non-Compliant Stablecoins

ESMA’s feedback highlights a major push to strengthen enforcement and eliminate regulatory arbitrage ¹. The regulator has proposed stricter marketing rules for crypto-assets, focusing heavily on promotions led by influencers and third-party marketers ¹.

To protect the EU market from external risks, ESMA is seeking reinforced supervisory powers to target third-country firms that solicit EU investors without holding a valid MiCA authorization ¹. The regulator also wants explicit rules that ban regulated EU crypto firms from offering any services linked to stablecoins that do not comply with MiCA's strict issuance requirements ¹.

Additionally, ESMA is requesting the direct capacity to detect, block, and deactivate fraudulent websites, as well as freeze crypto-assets when there is suspicion of market abuse or terrorist financing ¹.

Implications for the European Digital Asset Market

If accepted by the European Commission, these proposals will significantly raise the compliance burden for crypto-asset service providers (CASPs) operating in Europe. Firms offering access to DeFi front-ends or yield-bearing products like staking will face rigorous disclosure and licensing requirements ¹.

However, ESMA has framed these changes as part of the EU's broader simplification and burden-reduction agenda ¹. To offset the new compliance hurdles, the regulator has proposed streamlining white-paper notification procedures, reducing duplicate authorization requirements for already-regulated financial institutions, and aligning prudential requirements more consistently ¹. Looking further ahead, ESMA also emphasized the necessity of building a dedicated framework for tokenized securities and on-chain settlement to support an integrated European tokenized capital market ¹.

What to Watch Next

The European Commission's consultation on the functioning of MiCA closed to public and targeted stakeholder feedback on August 31 ³. The feedback gathered from ESMA, digital asset issuers, service providers, and the public will now be analyzed by the Commission to inform its future policy proposals and potential legislative revisions to the MiCA framework ³.
