This final report from the European Banking Authority (EBA) introduces new Implementing Technical Standards (ITS) for the supervisory reporting of Third Country Branches (TCBs) operating within the European Union. Established under the CRD VI regulatory package, these standards create a harmonized framework to replace fragmented national rules and ensure effective oversight of foreign banking entities. The reporting requirements are structured around a proportionality principle, distinguishing between Class 1 and Class 2 branches to tailor the volume and frequency of data collection based on an entity's size and risk. Under the new mandate, branches must submit standardized templates covering their own financial and regulatory health, as well as critical information regarding their head undertakings and wider group activities. To ease the transition, the EBA has simplified several data requirements and set the initial reporting deadline for March 31, 2027. This initiative ultimately aims to strengthen financial stability and create a level playing field across the EU banking sector.
