Inside this Topic Guide

Banking Union comprises the following elements:
- the Single Supervisory Mechanism (SSM), which makes the European Central Bank (ECB) the common supervisor for euro area banks with direct supervisory responsibility for "significant" SSM banks. For less significant SSM banks, national supervisors are responsible for day-to-day supervision subject to the control of the ECB;
- the Single Resolution Mechanism (SRM), which is a system for resolving failing euro area banks and applies the Bank Recovery and Resolution Directive (BRRD) to SSM banks in a uniform manner via a Single Resolution Board (SRB) and a shared fund to cover costs paid for by banks (Single Resolution Fund - SRF); and
- a proposed European Deposit Insurance Scheme (EDIS) – in November 2015 the Commission presented a legislative proposal for a system initially based on reinsurance, which will keep in place Member States' national schemes established under the recast Deposit Guarantee Scheme Directive (DGSD2).
In addition, the system is underpinned by a facility for the direct recapitalisation of failing banks by the European Stability Mechanism (ESM).
Details of legislation establishing the Banking Union are available in the legislation section of this guide.
The SSM and the SRM also include non-euro area Member States with which the ECB has established close cooperation arrangements (currently, Bulgaria and Croatia are also participating Member States).
Fundamentally, the aim of the SSM and SRM is to ensure uniform implementation within the participating Member States of the "single rulebook" being the broader set of legislative instruments with which all EU banks (inside and outside the euro area) must comply including:
- Capital Requirements Directive/Regulation (CRD / CRR) (as amended, including by CRDV / CRR2)
- Bank Recovery and Resolution Directive (BRRD) (as amended, including by BRRD2)
- Deposit Guarantee Schemes Directive 2 (DGSD2)
Under the draft Investment Firms Directive (IFD) and Investment Firms Regulation (IFR) some systemically important investment firms may be reclassified as credit institutions and therefore become subject to the SSM.
