A commercial bank is a financial institution that accepts deposits from the public and gives loans for the purposes of consumption and investment to make a profit.
It can also refer to a bank or a division of a larger bank that deals with corporations or large or middle-sized businesses, to differentiate from retail banks and investment banks. Commercial banks include private sector banks and public sector banks. However, central banks function differently from commercial banks, despite a common misconception known as the "bank analogy". Unlike commercial banks, central banks are not primarily focused on generating profits and cannot become insolvent in the same way as commercial banks in a fiat currency system.

## History

The name bank derives from the Italian word banco 'desk/bench', used during the Italian Renaissance era by Florentine bankers, who used to carry out their transactions on a desk covered by a green tablecloth. However, traces of banking activity can be found even in ancient times.
In the United States, the term commercial bank was often used to distinguish it from an investment bank due to differences in bank regulation. After the Great Depression, through the Glass–Steagall Act, the U.S. Congress required that commercial banks only engage in banking activities, whereas investment banks were limited to capital market activities. This separation was mostly repealed in 1999 by the Gramm–Leach–Bliley Act.

## Role

The general role of commercial banks is to provide financial services to the general public and business, ensuring economic and social stability and sustainable growth of the economy.
In this respect, credit creation is the most significant function of commercial banks. While sanctioning a loan to a customer, they do not provide cash to the borrower. Instead, they open a deposit account from which the borrower can withdraw. In other words, while sanctioning a loan, they automatically create deposits.

* The function of credit creation is generated on the basis of credit and payment intermediary. Commercial banks use the deposits they absorb to make loans. On the basis of check circulation and transfer settlement, the loans are converted into derivative deposits. To a certain extent, the derivative funds of are increased by interval times the original deposits which greatly improves the driving force of commercial banks to serve the economic development.
