Challenges to an Efficient European Centralised Banking Supervision (SSM): Single Rulebook, Joint Supervisory Teams and Split Supervisory Tasks.

The establishment of centralized supervision by means of the Single Supervisory Mechanism (SSM) had to ensure the quality and impartiality of banking supervision, as well as the establishment of a supervisory system more properly aligned with the characteristics of the banking sector. The far-reaching mixed administration of the European Central Bank (ECB) and national competent authorities (NCAs) must also ensure strong and consistent supervision across the participating member states while using the NCAs' local and specific know-how. All elements indicate that a more effective banking supervision was necessary for the Eurozone. This may be challenging given the conflict between the required centralisation of supervision, on the one hand, and the far-reaching mixed administration and composite legal order in place on the other. The first years of experience with the SSM provide a multi-faceted picture of the effectiveness of centralised supervision. This paper discusses the effectiveness of centralised supervision within the context of a far-reaching mixed administration and legal order on the basis of three different elements. Firstly, the basis of supervision is discussed, i.e. the applicable substantive laws for which compliance must be ensured by the ECB, and which concerns the so-called Single Rulebook. Secondly, the organisation of supervision, in practice, is discussed on the basis of one of its most important features: the Joint Supervisory Teams. Lastly, the delineation of supervisory tasks is discussed, as well as its impact on the ECB and, based on the Dutch example, its impact on national supervisory models. These elements illustrate the many steps that have been taken to improve the effectiveness of centralised supervision. They also show how many obstacles are still left to overcome.
