ESMA publishes updated registration guide for expanded supervisory mandate
The European Securities and Markets Authority (ESMA) has published an updated guide detailing registration requirements across its expanding supervisory mandate. The guide, released on 14 August 2025, covers registration processes for credit rating agencies, trade repositories, benchmark administrators, data reporting services providers, external reviewers under EU Green Bond Regulation (EU) 2023/2631, and environment, social and governance (ESG) rating providers under ESG Rating Regulation (EU) 2024/3005. ESMA will begin accepting endorsement applications for benchmarks from 1 October 2025, ahead of assuming supervision of endorsed benchmarks on 1 January 2026. Technical standards for external reviewers are awaiting European Parliament and Council non-objection, while ESG rating provider standards are under development.
