From regulatory perspective, the Banking System in the USA is very different from the Indian banking system. Bank in United States can be classified into 2 main categories:
National banks are incorporated and operated under the laws of the United States. These banks are subject to the approval office of the comptroller of the currency (OCC). Membership of Federal Reserve System is required for all national banks. The biggest advantage of belonging to the Federal Reserve System is that deposits in the member banks are automatically insured by the FDIC. The FDIC protects each account in a member bank for up to $100,000 if the member bank becomes insolvent.
State-chartered banks are granted authority by the state in which it carries out business and are under the regulation of an appropriate state agency. State-chartered banks can choose to belong to the Federal Reserve System to ensure they are insured by FDIC. Non-members banks of the Federal Reserve System can also be protected by the FDIC if they can meet certain requirements and submit an application for the same.
