In a pension blog, De Nederlandsche Bank explains that supervision of funds that have moved to the new pension system now shifts from assessing irreversible pre-transition choices, such as how fund assets are allocated, to checking whether the transition has been executed as intended. As of 1 January 2026, 24 pension funds had moved to the new system, joining six that had done so earlier, and more than half of all pension participants now have part or all of their pension under the new system. For funds that transitioned in January, the following weeks and months are used to complete the transition by finalising benefit payments and individual pension assets once the year-end funding ratio is known and figures and calculations have been checked. Funds are also checking IT systems. No new decisions are taken at this stage, with the emphasis instead on careful execution because the transfer from collective pension assets to individual pension assets can only be done once. DNB says this phase includes a new supervisory checkpoint, known as assessment point 2, where pension funds, together with their accountant and actuary, must demonstrate that the transition calculations were carried out correctly and completely and that the data are accurate. The central bank is also in discussions with funds planning to move to the new system this year or next year and says lessons from the funds that have already transitioned will inform that work.
