  • ESMA publishes new guidelines under MiCAR to prevent and detect market abuse

    9 July 2025
    The European Securities and Markets Authority (ESMA) has published official translations of its guidelines on supervisory practices to prevent and detect market abuse under the Markets in Crypto-Assets Regulation (MiCAR). The guidelines, initially released in April through a final report, outline general principles to promote high-quality and effective supervision of market abuse in crypto-assets, alongside more targeted practices to support national competent authorities (NCAs) in detecting and preventing such abuse. The guidelines will now apply from 9 October, being three months after their publication in all official EU languages. NCA's shall confirm by 9 September whether they comply or intend to comply with the guidelines. If an NCA does not comply or does not plan to comply, it must notify ESMA, providing the reasons for its position. ESMA will subsequently publish this information on its website.
