The European Securities and Markets Authority published the fifth edition of its Report on the Quality and Use of Data, setting out how EU authorities use regulatory data and what actions have been taken to improve data quality. It illustrates practical use cases across market monitoring, supervision, enforcement and policy making. Examples include ESMA’s reuse of existing data to support reporting burden reduction, such as using Markets in Financial Instruments Regulation transaction data to perform transparency and volume cap calculations. The report highlights ESMA’s Data Platform and ongoing enhancements to data quality frameworks, alongside updates on data quality work for European Market Infrastructure Regulation REFIT go-live datasets, a newly implemented data quality framework for short-selling data, first steps to improve the accessibility and use of European Single Electronic Format data by national competent authorities, and an overview of sanctions imposed by national competent authorities for reporting obligation breaches. A webinar presenting the report will be held on 15 May from 11:00 to 12:00 CET.
