A retail bank is a bank that works with consumers, otherwise known as 'retail customers'. Retail banks provide basic banking services to the general public, including:

• Checking and savings accounts
• CDs
• Safe deposit boxes
• Mortgages and second mortgages
• Auto loans
• Unsecured and revolving loans such as credit cards

Retail banks are the banks you most often see in cities on crowded intersections, the ones you probably use for your personal checking account.
In addition to helping consumers, retail banks often serve businesses as well - so they can also serve as commercial banks.

Retail banking is when a bank executes transactions directly with consumers, rather than corporations or other banks. Services offered include savings and transactional accounts, mortgages, personal loans, debit cards, and credit cards.

The term is generally used to distinguish these banking services from investment banking, commercial banking or wholesale banking. It may also be used to refer to a division of a bank dealing with retail customers and can also be termed as Personal Banking services.

In the US the term Commercial bank is used for a normal bank to distinguish it from an investment bank. After the great depression, through the Glass–Steagall Act, the U.S. Congress required that banks only engage in banking activities, whereas investment banks were limited to capital markets activities.

This separation was repealed in the 1990s. Commercial bank can also refer to a bank or a division of a bank that mostly deals with deposits and loans from corporations or large businesses, as opposed to individual members of the public (retail banking).
