Basal Norms are the banking supervision and regulatory norms published by the Basel Committee on Banking Supervision (BCBS). There are three versions of the Basel Norms like Basel I, Basel II and Basel III; they are called as Basel Accords. Basel norms are widely used in the banking and financial sector across the world because of its effectiveness and usefulness.
