EBA's harmonized reporting standards for TCBs under CRD VI
On March 5, 2026, the European Banking Authority (EBA) published its final report on the draft Implementing Technical Standards (ITS) establishing new harmonized reporting standards for third-country branches (TCBs) under the Capital Requirements Directive VI (CRD VI). This marks a significant move away from the previously fragmented national rules. With the first reports now due on March 31, 2027, the clock is ticking for TCBs to prepare for a new era of enhanced oversight and transparency.
The drive to create a harmonized TCB regime was born out of necessity. Before CRD VI, the supervision of TCBs was left to individual member states, resulting in a patchwork of inconsistent rules. This fragmentation created supervisory gaps, an unlevel playing field, and the potential for regulatory arbitrage. Given that TCBs and other non-EU entities manage a significant portion of total EU banking assets, regulators identified this lack of a unified approach as a potential risk to the EU's financial stability.
The new framework, a key part of the CRD VI package, aims to address these challenges by establishing common minimum requirements for the licensing, supervision, and reporting of all TCBs operating within the Union.
EBA's final draft ITS establishes a comprehensive reporting framework to provide supervisors with consistent, high-quality data. The overall package aims to achieve this while ensuring proportionality, clarity, and operational feasibility for reporting entities. The new framework introduces uniform formats, definitions, and reporting frequencies to ensure consistent and comprehensive reporting across the EU. Reflecting feedback from the public consultation, the final draft report incorporates several key enhancements and simplifications to ease the implementation burden. These include:
What are EBA's harmonized reporting standards for TCBs under CRD VI?
The EBA third-country branches (TCBs) harmonized reporting standards are a new framework under CRD VI designed to replace fragmented national rules. They introduce a proportionate, two-tiered system that require TCBs to submit detailed reports on both their own operations and their parent head undertaking, with a first deadline of March 31, 2027.
Navigating the new era of third-country branch reporting in the EU
At the heart of this new regulation is a proportionate, two-tiered reporting framework. Proportionality is achieved by classifying TCBs based on their size, risk, and activities, which in turn dictates the scope and frequency of their reporting obligations through a "core + supplement" approach.
CLASSIFICATION
Class 1 Branches (Larger and more complex): A branch is designated as Class 1 if it meets certain criteria, such as having locally booked assets of €5 billion or more, taking significant retail deposits, or not being a 'qualifying branch' from an equivalent supervisory regime. These branches are subject to the full "supplement" of reporting requirements, which provide more granular detail and more frequent reporting.
Class 2 Branches (Smaller and less complex): TCBs that do not meet the Class 1 criteria fall into this category. They benefit from a more streamlined regime, submitting only the "core" set of key data less frequently.
REPORTING
Branch-level information: This includes detailed financial and regulatory data on the TCB itself, covering assets and liabilities, large exposures, capital endowment, and liquidity coverage calculations. The requirements for Class 1 branches in this area often mirror the complexity of existing EU frameworks like COREP and FINREP.
Head-undertaking information: This set of templates requires both quantitative and qualitative data on the parent entity, covering areas such as its prudential compliance, significant supervisory reviews, recovery plans, and overall business strategy in relation to its EU branches.

The transition to this new harmonized regime presents several challenges for impacted firms.
Increased complexity and granularity
The new templates demand a level of detail that goes far beyond previous requirements, including new data on originated assets and liabilities and extensive information on the head undertaking.
Operational strain
For many TCBs, moving from manual, disparate reporting processes to an automated, harmonized system will be a significant operational undertaking. This includes building new systems and processes to collect, consolidate, and validate data that may not be readily available.
Data sourcing from head undertakings
A significant challenge highlighted during the EBA's consultation is the difficulty in obtaining timely and verifiable information from head undertakings, especially for smaller branches with limited infrastructure.
Tight implementation timeline
Despite the postponement, the March 31, 2027 deadline requires firms to act now to implement the necessary changes to their data architecture, governance, and reporting systems.
Who is impacted by the new TCB reporting rules?
The new regulation impacts all third-country undertakings with branches in the EU. As of 2025, there are about 89 branches from 61 non-EU groups. These institutions must now navigate the new classification system and prepare to meet the detailed reporting requirements applicable to their specific class. The rules apply to the supervised TCBs, which are the entities obligated to submit the reports.
Navigating the new era of third-country branch reporting in the EU
While the transition to the new harmonized TCB regime presents significant operational hurdles, it also offers firms a strategic opportunity to enhance and automate compliance processes. The move towards a standardized framework streamlines data aggregation and reporting, leading to long-term efficiency gains.
Navigating this complex transition requires a specialized, purpose-built solution. Regnology Reporting Hub (RRH) is a comprehensive platform designed to address the full scope of the new EBA ITS for third-country branches. Powered by RGI, Regnology's integrated regulatory intelligence layer, RRH automates the entire reporting lifecycle, from data aggregation to final submission.
