A commercial bank is a financial institution that grants loans, accepts deposits, and offers basic financial products such as savings accounts and certificates of deposit to businesses, as opposed to a retail bank that provides similar financial products to individuals. A commercial bank makes money primarily by providing different types of loans to customers and charging interest.
The bank’s funds come from money deposited by the bank customers in saving accounts, checking accounts, money market accounts, and certificates of deposit (CDs). The depositors earn interest on their deposits with the bank. However, the interest paid to depositors is less than the interest rate charged to borrowers. Some of the loans offered by a commercial bank include motor vehicle loans, mortgages, business loans, and personal loans.
Functions of Commercial Banks
The basic role of a commercial bank is to provide financial services to businesses and companies. Banks also ensure economic stability and the sustainable growth of a country’s economy. To learn more about the different roles available in a commercial bank, see CFI’s Careers in Commercial Banking course. A commercial bank performs the following functions:
1. Accepting Deposits
Accepting deposits is one of the oldest functions of a commercial bank. When banks started, they charged a commission for keeping money on behalf of the public. With the changes in the banking industry over the years and the profitability of the business, banks now pay a small amount of interest to the depositors who keep money with them. However, depositors also incur administrative fees to maintain their accounts.
Banks accept three types of deposits. The first one is the savings deposit for small savers who are paid interest on their accounts. They can withdraw their money up to a limited amount by writing a cheque.
The second type of deposit is the current account for people in business who can withdraw their money at any time without notice. Banks do not typically pay interest on deposits held in current accounts. Instead, the account holders are charged a nominal fee for the services rendered.
The last type of deposit is the term or fixed deposit. Customers who have money that they do not need for the next six months or more can save in the fixed account. The rate of interest paid increases with the length of the fixed deposit. Customers can only withdraw the money at the end of the agreed period by writing to the bank.
2. Advancing Credit Facilities
Advancing loans is an essential function of banks since it accounts for the highest percentage of revenue earned annually. Banks mostly offer short-term and medium-term loans from a percentage of the cash deposits at a high interest rate.
They do not provide long-term financing due to the need to maintain the liquidity of assets. Before advancing loans to customers, banks consider the borrower’s financial status, business profitability, nature and size of the business, and ability to repay the loan without default.
3. Credit Creation
While granting loans to customers, banks do not provide the loan in cash to the borrower. Instead, the bank creates a deposit account from which the borrower can draw funds. This allows the borrower to withdraw money by cheque according to his needs. By creating a demand deposit in the borrower’s account without printing additional money, the bank increases the amount of money in circulation.
4. Agency Functions
Commercial banks serve as agents of their customers by helping them in collecting and paying cheques, dividends, interest warrants, and bills of exchange. Also, they pay insurance premiums, utility bills, rent, and other charges on behalf of their clients.
Banks also trade shares, securities, and debentures, and they provide advisory services for customers that want to buy or sell these investments. In property administration, commercial banks act as trustees and executors of the estate on behalf of their customers. Banks charge a nominal fee for the agency functions performed on behalf of their clients.
Apart from the above primary functions, banks also perform several other functions. They provide foreign exchange to clients in import and export businesses by buying and selling foreign currency. However, banks must get permission from the regulatory body, mainly the central bank, before dealing with foreign exchange.
A commercial bank also acts as a custodian of precious stones and other valuables. They provide customers with lockers where they can put their jewelry, precious metals, and crucial documents. Such items are more secure when stored at the bank than keeping them at home, where they may be stolen or damaged.

Types of Loans Offered by Commercial Banks
There are several types of loans advanced by commercial banks to their clients. These loans include:
1. Bank Loan
A bank loan is an amount of money offered by a bank to a borrower at a defined interest rate for a fixed period. Before granting a bank loan to a client, a bank must obtain several important documents to verify that the borrower will pay back the loan. These documents may include copies of identity, proof of income, and audited financial statements in the case of corporate clients.
The loan is granted against collateral that, if the customer defaults, the bank can sell it to recover the money. The collateral may be equipment, machinery, real estate property, inventory, documents of ownership, and other items.
2. Cash Credit
Cash credit is an arrangement between the bank and a client, and it allows the client to withdraw money beyond their account limit. The cash credit is advanced for a period of one year, but it may extend to even three years in special circumstances.
The amount is deposited in the current account of the borrower and can be withdrawn through a cheque. The interest charged on the cash credit depends on the amount of money and the duration for which the money has been withdrawn.
3. Bank Overdraft
A bank overdraft is a form of financing that allows the current account holders to overdraw their account up to a specified limit. It does not require any written formalities, and clients use the overdraft to meet urgent needs. Interest is charged on the amount that the current account has been overdrawn with and not the full amount of overdraft allowed by the bank.
4. Discounted Bills of Exchange
A bank discounts a bill of exchange by providing money immediately to the holder of the bill. The bank deposits the money in the holder’s current account after deducting an interest rate for the loan period. Once the bill of exchange matures, the bank gets its payment from the banker of the bill holder.
Regulation by Central Banks
Commercial banks are regulated by the central banks in their respective countries. Central banks act as the supervisor of commercial banks, and they impose certain regulations to ensure banks operate within the stipulated rules.
For example, central banks make it mandatory for commercial banks to maintain bank reserves with them. Some central banks set the minimum bank reserves, requiring banks to keep a particular percentage of their customer deposits at the central bank. The reserves help to cushion banks against unexpected events like bank runs and bankruptcy.
