EBA moves to standardise reporting for third-country bank branches
The European Banking Authority (EBA) has set out a new supervisory reporting framework for third-country bank branches operating in the EU, paving the way for a forthcoming XBRL taxonomy to support harmonised data collection across member states.
In a final report on draft Implementing Technical Standards (ITS) under the EU’s updated banking legislation, the Capital Requirements Directive VI (CRD VI), the EBA outlines a reporting regime designed to give supervisors clearer, more consistent insight into the activities of EU branches whose parent institutions are headquartered outside the bloc.
At its core is a push for harmonisation. The new regime introduces common reporting formats, definitions and reporting frequencies designed to ensure supervisors across the EU are working with comparable data, without overburdening reporting institutions.
Under the proposal third-country branches will submit two sets of templates: one covering branch-level financial and regulatory information, and another capturing quantitative and qualitative data relating to the head undertaking. To keep the burden proportionate, smaller branches will report a reduced core dataset, while larger institutions will provide additional detail.
For the digital reporting community, the next step will be closely watched. Once the standards are adopted by the European Commission, the EBA plans to develop the associated data point model (DPM), XBRL taxonomy and validation rules that will power the technical reporting framework. The full technical package is expected in the second quarter of 2026.
Taken together, the initiative reinforces a familiar regulatory direction of travel: supervision built on structured, machine-readable data. As the framework takes shape, XBRL-based reporting will play an expanding role in how Europe monitors the activities of global banks operating within its borders.
