Establishing close cooperation with supervisors ensures that synergies between these central bank and supervisory activities can be exploited. In addition, close cooperation enhances the efficiency of the supervisory system by reducing overlaps of work.

Practical cooperation can be organised fairly informally with regular high-level discussions on how to deal with strategic issues and problems as well as by the creation of working groups to deal with specific topics.
