EMIR Refit (Regulation (EU) 2019/2099) introduces updated EMIR Refit validation rules for reporting under the European Market Infrastructure Regulation (EMIR). These rules are pivotal in ensuring the accuracy, completeness, and consistency of reported derivatives transaction data. They mandate that reporting entities, including financial counterparties and non-financial counterparties above the clearing threshold, adhere strictly to prescribed formats, allowable values, and logical relationships between data fields.
