ESMA will begin supervising ESG rating providers in 2027

ESMA will process applications from ESG rating providers and begin supervising the sector during 2027, one of several new or expanding remits in the annual work programme the EU markets regulator has set out, alongside oversight of consolidated tape providers, the external reviewers of European Green Bonds and broader responsibilities for benchmark administrators. For anyone tracking disclosure, the ratings line matters most: investors and companies lean on ESG assessments for capital allocation, risk management and sustainability strategy, according to ESG News, and from 2027 the firms producing them sit inside the regulated perimeter.

The registration window has been forming for months: in August this publication examined the 2 November filing deadline that opens the regime, and the argument that competition among raters will not by itself hold standards up. ESMA's work programme now puts the supervision that follows on the calendar, as the EU's wider capital-markets reforms move from design into implementation.

The programme sits within ESMA's 2023–2028 strategy and supports the EU's Savings and Investments Union, which seeks to channel European savings toward productive investment and build deeper, more competitive capital markets. Verena Ross, ESMA's chair, called 2027 a milestone as many of the regulator's strategic initiatives move into delivery, noting that co-legislators are still working on the Market Integration and Supervision Package while ESMA advances elements of the SIU agenda, including simplification of the regulatory, reporting and supervisory framework.

Digital resilience and clearing fill out the year, with ESMA working alongside the other European Supervisory Authorities to oversee critical third-party ICT service providers and keep monitoring compliance with the Digital Operational Resilience Act across its remit. It will also review how the EMIR 3 reforms are affecting EU clearing markets, where the stated aim is clearing houses that stay resilient while dependence on certain systemically important clearing services elsewhere comes down. ESMA says it will make heavier use of data, artificial intelligence and technology to oversee increasingly complex markets.

Simplification and supervision are arriving in the same document. ESMA is promising lighter reporting and adding sectors to its perimeter at once, and what its first tranche of ESG rating applications yields will show how much that perimeter is worth in practice. Benchmark administrators, tape providers and green bond reviewers are queued behind the raters for the same treatment, though the work programme sets the sequence rather than the volume and does not say how many rating applications ESMA expects to process. The co-legislators working through MISP still have to settle the framework around all of it.
