The Office of the Comptroller of the Currency (OCC) is comprehensively revising its regulations governing the international operations of national banks and the operation of foreign banks through Federal branches and agencies in the United States. The revision is part of the OCC's Regulation Review Program, which seeks to simplify OCC regulations and reduce unnecessary compliance costs, consistent with maintaining safety and soundness and furthering the other responsibilities of the OCC. The final rule streamlines and consolidates into one part of the Code of Federal Regulations substantially all provisions relating to international banking, and clarifies and simplifies their various requirements. The final rule also updates the rules to implement provisions of the Foreign Bank Supervisory Enhancement Act of 1991 (FBSEA) and the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 (Interstate Act) relating to Federal branches and agencies.
