High Quality Content by WIKIPEDIA articles! Bank regulation in the United States is highly fragmented compared with other G10 countries, where most countries have only one bank regulator. In the U.S., banking is regulated at both the federal and state level. Depending on the type of charter a banking organization has and on its organizational structure, it may be subject to numerous federal and state banking regulations. Unlike Japan and the United Kingdom (where regulatory authority over the banking, securities and insurance industries is combined into one single financial-service agency), the U.S. maintains separate securities, commodities, and insurance regulatory agencies—separate from the bank regulatory agencies—at the federal and state level.
