The Single Supervisory Mechanism (SSM) is the legislative and institutional framework that grants the European Central Bank (ECB) exclusive competence to authorize and supervise banks in the eurozone. Yet, even in the context of such a high degree of Europeanization, the ECB is not completely autonomous but often relies on the powers and expertise of the national supervisors (NCAs). Various final decisions are therefore adopted on the basis of composite administrative procedures. While SSM procedures are indeed highly integrated, the protection of fundamental rights is split between the EU and the national legal orders, which may lead to gaps in complete fundamental rights protection.
