SSM meaning in Banking ?

The Single Supervisory Mechanism (SSM) is the first pillar of the European banking union and is the legislative and institutional framework that grants the European Central Bank (ECB) a leading supervisory role over banks in the EU. The ECB directly supervises the larger banks while it does it indirectly for the smaller ones. Eurozone countries are required to participate, while participation is voluntary for non-eurozone EU member states. In October 2020, two non-Eurozone countries joined the European banking supervision mechanism through a process known as close cooperation: Bulgaria and Croatia. As of early 2021, the SSM directly supervises 115 banks across the Union, representing almost 82% of banking assets of these countries. The SSM, along with the Single Resolution Mechanism are the two central components of the European banking union.
