Should non-euro area countries join the single supervisory mechanism?

Highlights - Irrespective of the euro crisis, a European banking union makes sense, including for non-euro area countries, because of the extent of European Union financial integration. The Single Supervisory Mechanism (SSM) is the first element of the banking union. - From the point of view of non-euro countries, the draft SSM regulation as amended by the EU Council includes strong safeguards relating to decision-making, accountability, attention to financial stability in small countries and the applicability of national macro-prudential measures. Non-euro countries will also have the right to leave the SSM and thereby exempt themselves from a supervisory decision. - The SSM by itself cannot bring the full benefits of the banking union, but would foster financial integration, improve the supervision of cross-border banks, ensure greater consistency of supervisory practices, increase the quality of supervision, avoid competitive distortions and provide ample supervisory information. - While the decision to join the SSM is made difficult by the uncertainty about other elements of the banking union, including the possible burden sharing, we conclude that non-euro EU members should stand ready to join the SSM and be prepared for the negotiations of the other elements of the banking union
