The Congress declares that it is the purpose of this subchapter to provide for the establishment of international banking and financial corporations operating under Federal supervision with powers sufficiently broad to enable them to compete effectively with similar foreign-owned institutions in the United States and abroad; to afford to the United States exporter and importer in particular, and to United States commerce, industry, and agriculture in general, at all times a means of financing international trade, especially United States exports; to foster the participation by regional and smaller banks throughout the United States in the provision of international banking and financing services to all segments of United States agriculture, commerce, and industry, and, in particular small business and farming concerns; to stimulate competition in the provision of international banking and financing services throughout the United States; and, in conjunction with each of the preceding purposes, to facilitate and stimulate the export of United States goods, wares, merchandise, commodities, and services to achieve a sound United States international trade position. The Board of Governors of the Federal Reserve System shall issue rules and regulations under this subchapter consistent with and in furtherance of the purposes described in the preceding sentence, and, in accordance therewith, shall review and revise any such rules and regulations at least once every five years, the first such period commencing with the effective date of rules and regulations issued pursuant to section 3(a) of the International Banking Act of 1978, in order to ensure that such purposes are being served in light of prevailing economic conditions and banking practices.
