Risks for the safety and soundness of a credit institution can arise both at the level of an individual credit institution and at the level of a banking group or of a financial conglomerate. Specific supervisory arrangements to mitigate those risks are important to ensure the safety and soundness of credit institutions. In addition to supervision of individual credit institutions, the ECB’s tasks should include supervision at the consolidated level, supplementary supervision, supervision of financial holding companies and supervision of mixed financial holding companies, excluding the supervision of insurance undertakings.
