This paper represents one of the first comparative analyses of experiences of integrated supervision. It discusses how several countries around the world have developed the processes of integrating financial regulation and supervision, and covers numerous relevant technical issues as well as the policy options. It describes the scope of the activities, institutions, responsibilities, and regulatory powers that integrated supervisors are expected to cover. Issues related to the organizational structures and the management of staff resources are also considered. In particular, the paper discusses how the supervisory agencies have dealt with three important aspects: the treatment of financial conglomerates, the risk assessment process, and crisis management.
