As a first step towards a banking union, a single supervisory mechanism should ensure that the Union’s policy relating to the prudential supervision of credit institutions is implemented in a coherent and effective manner, that the single rulebook for financial services is applied in the same manner to credit institutions in all Member States concerned, and that those credit institutions are subject to supervision of the highest quality, unfettered by other, non-prudential considerations. In particular, the Single Supervisory Mechanism (SSM) should be consistent with the functioning of the internal market for financial services and with the free movement of capital. A single supervisory mechanism is the basis for the next steps towards the banking union. This reflects the principle that the ESM will, following a regular decision, have the possibility to recapitalise banks directly when an effective single supervisory mechanism is established. The European Council noted in its conclusions of 13/14 December 2012 that ‘In a context where banking supervision is effectively moved to a single supervisory mechanism, a single resolution mechanism will be required, with the necessary powers to ensure that any bank in participating Member States can be resolved with the appropriate tools’ and that ‘the single resolution mechanism should be based on contributions by the financial sector itself and include appropriate and effective backstop arrangements’.
