The Union has reached the limits of what can be done with the present status of the Committees of European Supervisors. The Union cannot remain in a situation where there is no mechanism to ensure that national supervisors arrive at the best possible supervisory decisions for cross-border financial market participants; where there is insufficient cooperation and information exchange between national supervisors; where joint action by national authorities requires complicated arrangements to take account of the patchwork of regulatory and supervisory requirements; where national solutions are most often the only feasible option in responding to problems at the level of the Union; and where different interpretations of the same legal text exist. The European System of Financial Supervision (hereinafter the ESFS’) should be designed to overcome those deficiencies and provide a system that is in line with the objective of a stable and single Union financial market for financial services, linking national supervisors within a strong Union network.
