The European Securities and Markets Authority has published updated reporting instructions and an updated XML schema (version 1.2.0) for weekly reporting of commodity derivatives positions under the Markets in Financial Instruments Directive II (MiFID II), reflecting changes arising from the latest review. The package incorporates MiFID II-related changes including the requirement to publish two weekly reports and the exclusion of (spot) emission allowances from position reporting. It also introduces amendments linked to Implementing Technical Standard 4 (ITS 4), including harmonisation of reporting units for energy derivatives. These adjustments are based on ESMA’s Final Report submitted to the European Commission in December 2024, which is pending adoption, and are intended to provide a consistent reporting framework while reducing the need for frequent schema updates. ESMA will start applying the new XML schema and reporting instructions on 1 April 2026, from which point reporting entities should use only version 1.2.0.
