Dutch regulator boosts investor protection reporting with XBRL

De Nederlandsche Bank (DNB) has announced key changes to the annual data request under the Dutch Investor Compensation Scheme (ICS), coming into effect for 2025 data submissions due in early 2026. The headline news? A brand-new XBRL taxonomy and expanded reporting scope.
From 2026, financial institutions must report data for all four quarters of the year, not just the fourth as they have been doing until now. This quarterly breakdown will give DNB deeper insights into fluctuations and trends across the investment landscape. Crucially, DNB has rolled out an XBRL taxonomy to underpin the process, aiming to improve data quality and streamline regulatory oversight.
Institutions can still use Excel, with DNB converting submissions to XBRL, or, for those ready to take the plunge, they can file directly in XBRL. This is a shift towards greater automation and standardisation in the Netherlands, signifying ongoing improvements to digital reporting maturity.
Expanded use of XBRL supports supervisory efficiency and enhances transparency and accuracy, which is vital in protecting non-professional investors.
