DNB extends the period during which it will not prioritise supervisory and enforcement action in relation to the boundary between the banking book and the trading book. This follows the recent call by the European Banking Authority (EBA) for competent authorities to not prioritise the enforcement of these provisions.

The call follows the announcement of temporary amendments to the Fundamental Review of the Trading Book (FRTB), the revised market risk framework. For credit institutions under DNB’s direct supervision, supervisory and enforcement action in relation to the relevant FRTB boundary provisions and certain related reporting requirements will not be prioritised until 31 December 2029.

On 3 August 2026, the EBA published a statement on the application of these provisions following the European Commission’s third Delegated Act (DA) of 4 June 2026 (link). The DA introduces temporary operational adjustments to the revised market risk framework.

Operational complexity 

The EBA considers that the current framework may give rise to significant operational complexity and legal uncertainty. It therefore recommends that competent authorities do not prioritise supervisory or enforcement action in relation to the relevant FRTB boundary provisions and related reporting requirements during this period.

DNB will follow the EBA's opinion for credit institutions under its direct supervision. Nevertheless, DNB considers it important that institutions continue their preparations for the full implementation of the revised market risk framework. This includes the provisions setting the boundary between the banking book and the trading book.
