Transaction Reporting

Transaction-level reporting under EU markets regulation: MiFIR Article 26 trade reports to NCAs, EMIR derivatives reporting to trade repositories, SFTR for securities financing transactions, and the ESMA active account requirement under EMIR 3.0. This section also covers EMIR initial margin reporting and the IM model authorisation regime now applying to firms above the IM threshold. Articles explain the field-level requirements, lifecycle events (new, modify, terminate, error correction), reconciliation expectations, and the most common reporting errors that trigger NCA queries. Start with the MiFIR transaction reporting guide for the Article 26 fundamentals or the EMIR reporting guide for derivatives reporting essentials.
