Indeed, in my view the Lead Supervisor model requires a close working relationship between the host and the home supervisors so as to achieve effective supervision.
The home supervisor, referred to as the lead supervisor, is given final authority to set the reporting requirements for the entire group, to coordinate the validation of its internal models at the group and local levels, as well as the planning of on-site bank inspection regimes, and to co-ordinate the authorisation process. The concept of Lead Supervision promotes greater efficiency.
