A bank is a regulated financial institution that accepts deposits, offers checking and savings accounts, provides loans, and facilitates monetary transactions for individuals and businesses. As a core part of the financial system, banks operate under strict regulatory oversight to ensure consumer protection, market stability, and secure money management. Banks also support economic growth by using deposited funds to issue credit, manage payments, and offer financial products such as mortgages, business loans, and investment services.
Unauthorized Banks List
The Office of the Comptroller of the Currency (OCC) issues alerts to provide information about entities engaged in unauthorized banking activities, both offshore and domestic. The alphabetical Unauthorized Banks List, which contains bulletins from 1994 to the present, is intended to aid in the search for names of such entities and detail the problem that prompted the issuance.
