Rather than collecting most returns itself, it mostly writes the technical standards, guidelines and reporting templates that define how firms report to National Competent Authorities (NCAs) or to trade repositories ESMA registers and supervises, and it directly supervises certain entities (trade repositories, credit rating agencies, data reporting services providers).

For every regime except FIRDS and MMFR, the firms report to a National Competent Authority or a trade repository, not to ESMA itself; each return below says who receives it, rather than implying ESMA collects the data centrally. CSDR reporting and SSR (short-selling) reporting are named on the same hub page but were not read this session and are left out. It does not repeat the European Banking Authority's or EIOPA's returns, which the library covers under those authorities; where an EU banking or insurance return is an EBA or EIOPA return, it is not repeated here.","source":"https://www.esma.europa.eu/data-reporting"},"submission_systems":[],"licence":{"name":"ESMA: Legal Notice and Data Protection","quote":"Reproduction of all information on this site (ESMA Library) is authorised except as otherwise stated, provided the source is acknowledged [...] if the original material is transformed [...] this must be stated explicitly.","url":"https://www.esma.europa.eu/about-esma/legal-notice-and-data-protection","checked":"2026-11-13","redistribution":"allowed with conditions","conditions":"Credit: acknowledge ESMA as the source.
