France, in contrast, has established a coordinating body for the central bank and the supervisory agencies, which have been partly reformed but remain independent from each other. It is essential that national structures need to mirror broadly the European setup to ensure consistency. This entails the necessity for coordination between involved bodies or within the designated authority.
Last but not least, all supervisory and organisational decisions have to be approved by a common board, so that all national competent authorities have their say in the joint architecture. In everyday-life, the vast amount of decisions consume quite a lot of resources in national authorities.
