The international framework for supervision of multi-national banks The internationally-agreed framework for the supervision of multinational banks, as devised by the Basel Committee on Banking Supervision, is known as the Basel Concordat (not to be confused with the Basel Accord on capital standards for banks).
The Concordat assigns clear, and deliberately overlapping, roles to the supervisors of multinational banks in those banks’ “home” and “host” countries. The home country supervisor is responsible for consolidated supervision of the global bank. It sets standards to be met on a group consolidated basis, for example, that group capital is sufficient to support the global business.
