Define a Bank

A bank is a financial institution licensed to receive deposits and make loans. Banks may also provide financial services, such as wealth management, currency exchange and safe deposit boxes. There are two types of banks: commercial/retail banks and investment banks. In most countries, banks are regulated by the national government or central bank.

• Commercial banks are typically concerned with managing withdrawals and receiving deposits as well as supplying short-term loans to individuals and small businesses. Consumers primarily use these banks for basic checking and savings accounts, certificates of deposit (CDs) and home mortgages. Examples of commercial banks include JPMorgan Chase & Company and Bank of America Corporation.
• Investment banks focus on providing corporate clients with services such as underwriting and assisting with merger and acquisition (M&A) activity. Morgan Stanley and Goldman Sachs Group Inc. are examples of U.S. investment banks.
• Central banks are chiefly responsible for currency stability, controlling inflation and monetary policy and overseeing money supply. Several of the world's major central banks include the U.S. Federal Reserve Bank, the European Central Bank, the Bank of England, the Bank of Japan, the Swiss National Bank and the People’s Bank of China.
• While many banks have both a brick-and-mortar and online presence, some banks have only an online presence. Online-only banks often offer consumers higher interest rates and lower fees. Convenience, interest rates and fees are the driving factors in consumers' decisions of which bank to do business with. As an alternative to banks, consumers can opt to use a credit union. ​
