EFET and the FIA have published a schema which can be used for enhanced reporting of commodity derivatives and emissions positions under MiFID II. The press release can be found here and the schema can be found here. Trading venues and Investment Firms are obligated to report on venue positions and Economically Equivalent OTC deals to National Competent Authorities.
Earlier this year the European Commission adopted a recommended format for such reporting under MiFID II Implementing Technical Standard 4 (see here). the UK’s Financial Conduct Authority has issued a version of the schema for reporting positions under their jurisdiction. The enhanced schema extends the standard so that various pieces of useful information can be communicated. Such fields are marked as in column D of the spreadsheet.
While the focus of position reporting is on venues and Investment Firms, non Investment Firms can be asked to provide or verify certain pieces of information to venues about their positions for onward transmission, for example the hedge status.
