The ECB banking supervision is based on the same rules as local supervision (single rulebook), public information on the differences between both is not commonly available. While there are differences, these are on a practical level and only known to experts with insights on both locally and directly supervised banks. Avantage Reply prepared a review of these differences and the gaps of the client to these the previous year. The client wanted to have an update on these recommendations based on the progress that was made during the year, also with regard to the updated timeline to ECB supervision. To address these topics, Avantage Reply organised workshops with its subject matter experts and the client and reviewed the relevant documents provided by the client.
