The European Banking Authority Issues Guidance to Help European Union Banks Prepare for New Market Risk Rules

The European Banking Authority is helping European Union banks prepare for a major change in market risk management. The revised framework will take effect on 1 January 2027.

The authority has published a no-action letter and technical considerations to support the implementation of the Fundamental Review of the Trading Book (FRTB). These measures give banks and national supervisors clearer guidance during the transition to the new market risk rules.

For European Union banks, the announcement provides greater clarity. It reduces uncertainty about how supervisors will apply key parts of the framework and helps institutions prepare with more confidence.

What the European Banking Authority announced

The European Banking Authority released two important documents. The first is a no-action letter that addresses the boundary between the trading book and the banking book. This remains one of the most complex parts of the FRTB framework.

The second document provides technical guidance for banks preparing for the revised market risk rules. It also explains how supervisors should approach the transition period.

Together, these documents aim to support consistent implementation across all European Union member states.

A temporary supervisory approach

The European Banking Authority recommends that national supervisors should not prioritize enforcement action on certain FRTB boundary provisions during the transition period.

This recommendation will remain in place until 31 December 2029. It does not suspend the underlying rules. Instead, it gives supervisors flexibility while the European Union finalizes legislative changes affecting trading book and banking book classifications.

Why the trading book boundary matters

The distinction between the trading book and the banking book plays a central role in bank capital regulation.

Trading assets are subject to market risk capital requirements, while banking book exposures follow a different prudential framework.

The FRTB introduces stricter rules for classifying positions and calculating market risk capital.

Because these classifications can significantly affect capital requirements, banks have asked for clearer guidance on how the boundary rules will work in practice. The no-action letter aims to provide that clarity during the transition period.

Technical guidance for the 2027 transition

The European Banking Authority also published technical guidance covering several practical aspects of implementation.

The guidance explains how banks should apply the revised market risk framework from 1 January 2027. It also covers supervisory benchmarking exercises, reporting expectations during the transition period, and broader implementation considerations for authorities and financial institutions.

These clarifications should help banks apply the framework consistently across the European Union.

Linked to broader reforms

The announcement accompanies the European Commission’s Delegated Act, which modifies the calculation of market risk capital requirements under the FRTB framework.

The FRTB reforms represent a major overhaul of the market risk regime developed under the Basel framework.

The reforms aim to improve market risk measurement, strengthen the relationship between internal risk models and regulatory capital requirements, and make capital calculations more risk-sensitive.

Banks will need to update their risk systems, trading book governance, reporting processes, and capital management frameworks to meet the new requirements.

Why the guidance matters for EU banks

Implementing the FRTB framework has created significant challenges for many institutions.

Banks have been preparing for the revised rules while legislative discussions on parts of the Capital Requirements Regulation continue.

Without additional guidance, member states could have adopted different implementation approaches. The European Banking Authority wants to promote a consistent approach across the European banking sector.

That consistency is particularly important for banks operating in multiple EU jurisdictions.

Reducing uncertainty during the transition

The no-action letter does not remove banks’ implementation obligations.

Institutions must continue preparing for the revised framework and developing the systems and governance required for FRTB compliance.

However, the European Banking Authority’s approach reduces the risk of enforcement pressure on certain provisions while the legislative framework continues to evolve.

That flexibility may allow banks to focus more on implementation, reporting readiness, and capital planning.

What happens next

The revised market risk framework will take effect on 1 January 2027.

Banks will continue preparing for implementation over the coming months.

National supervisors are expected to consider the European Banking Authority’s recommendations during the transition period.

Further amendments to the Capital Requirements Regulation may provide additional clarity on trading book rules before the transitional approach ends.

Looking ahead

The European Banking Authority’s no-action letter and technical guidance mark an important step in the rollout of the revised FRTB market risk framework.

By encouraging a consistent supervisory approach and reducing uncertainty around key technical provisions, the authority is helping banks prepare for a smoother transition.

For European Union banks, the guidance provides valuable regulatory clarity at a time when market risk reform remains one of the most significant implementation projects facing the European banking sector.

The guidance focuses on several key areas:

• application of the revised market risk framework from 1 January 2027,
• supervisory benchmarking exercises,
• reporting expectations during the transition period,
• and broader implementation considerations for authorities and financial institutions.

These measures will help banks implement the FRTB framework more consistently and prepare for the new market risk rules with greater certainty.
