DNB Extends Non-Enforcement Period for Banking and Trading Book Separation

Key Takeaways

• De Nederlandsche Bank (DNB) has announced an extension of its non-enforcement period regarding the separation of banking and trading books.
• This decision follows guidance from the European Banking Authority (EBA) to mitigate operational complexity and legal uncertainty during the implementation of the Fundamental Review of the Trading Book (FRTB).

Deep Dive

This regulatory update signifies a temporary reprieve for credit institutions under the direct supervision of DNB. By choosing not to prioritize supervisory or enforcement measures, the regulator is acknowledging the significant operational hurdles associated with the revised market risk framework. For compliance teams, this means that while the strict enforcement of separation rules and related reporting requirements is paused, the regulatory expectation for adherence remains intact.

The primary focus of this update relates to the FRTB provisions and the European Commission's third delegated act of June 4, 2026. The EBA’s recommendation to suspend enforcement was driven by the need to manage the operational complexity and legal uncertainty inherent in these technical adjustments. Consequently, compliance professionals should view this not as a removal of requirements, but as a window of leniency regarding formal enforcement actions.

The critical deadline mentioned is December 31, 2029. Until this date, DNB will not prioritize enforcement related to the separation between the banking and trading books or certain associated reporting mandates. This provides a clear timeline for institutions to finalize their internal processes and technical frameworks without the immediate pressure of regulatory sanctions for non-compliance with these specific provisions.

For compliance professionals, the recommended action is to maintain active preparation for full implementation. While enforcement is deferred, DNB explicitly stated that institutions must continue preparing for the revised market risk framework. This includes ensuring that data lineage, reporting capabilities, and internal controls are robust enough to meet the requirements once the non-enforcement period concludes.

From a risk perspective, the impact assessment should focus on operational readiness and capital adequacy. The risk of "false security" is high; if an organization treats this extension as a permanent reduction in standards, they may face significant gaps when enforcement resumes. Furthermore, because these provisions are tied to market risk frameworks, any failure to prepare could lead to unexpected impacts on capital requirements and regulatory reporting accuracy.
