In the United States, the banking industry is subject to many regulatory agencies, including the Federal Reserve, the Federal Deposit Insurance Corporation, the Office of the Comptroller of the Currency, the National Credit Administration, and the Office of the Superintendent of Savings, and as a state-level regulatory agency, it causes regulatory duplication, multiple regulatory standards and unequal competition among financial institutions.

Although European and American countries have set up financial supervision institutions, the government is more inclined to relax financial supervision. In the United States, the national policy of lifting the ban and relaxing financial supervision began with the Reagan administration. During Reagan's administration, many banking supervision laws were lifted, and the Garn Saint-Germain Act signed by Reagan directly led to the savings and loan crisis in the late 1980s. However, the abolition of the glass-steagall act signed by Clinton made the government give up martial arts and supervisory responsibility, which made financial derivatives popular on Wall Street until the current financial tsunami broke out.
