(43)In order to safeguard financial stability it is necessary to identify, at an early stage, trends, potential risks and vulnerabilities stemming from the micro-prudential level, across borders and across sectors. The Authority should monitor and assess such developments in the area of its competence and, where necessary, inform the European Parliament, the Council, the Commission, the other European Supervisory Authorities and the ESRB on a regular and, as necessary, on an ad hoc basis. The Authority should also, in cooperation with the ESRB, initiate and coordinate Union-wide stress tests to assess the resilience of financial institutions to adverse market developments, and it should ensure that an as consistent as possible methodology is applied at the national level to such tests. In order to perform its functions properly, the Authority should conduct economic analyses of the markets and the impact of potential market developments.
