The conferral of supervisory tasks on the ECB should be consistent with the framework of the ESFS and its underlying objective to develop the single rulebook and enhance convergence of supervisory practices across the whole Union. Cooperation between the banking supervisors and the supervisors of insurance and securities markets is important to deal with issues of joint interest and to ensure proper supervision of credit institutions operating also in the insurance and securities sectors. The ECB should therefore be required to cooperate closely with EBA, ESMA and EIOPA, the European Systemic Risk Board (ESRB), and the other authorities which form part of the ESFS. The ECB should carry out its tasks in accordance with the provisions of this Regulation and without prejudice to the competence and the tasks of the other participants within the ESFS. It should also be required to cooperate with relevant resolution authorities and facilities financing direct or indirect public financial assistance.
