How Commercial Banks Work
Commercial banks work by collecting money from people who save and lending it to people who need funds. They act as a bridge between depositors (people who save money) and borrowers (people who need loans).
1. Accepting Deposits
Commercial banks receive money from customers in different types of accounts such as savings accounts, checking accounts, current accounts, and fixed deposits. People keep their money in banks because it is safe and convenient. In return, the bank may pay interest on some of these deposits.
2. Lending Money
After collecting deposits, the bank lends part of that money to individuals, businesses, and organizations. Loans can be given for many purposes such as starting a business, buying a house, or paying school fees. The bank charges interest on the loans, which is one of its main sources of income.
3. Earning Profit
Commercial banks make a profit mainly from the difference between the interest they charge on loans and the interest they pay on deposits. This difference is called the interest margin.
4. Providing Payment Services
Banks help people make payments easily through services such as cheques, debit cards, credit cards, ATMs, online banking, and mobile banking. These services allow customers to transfer money and pay bills conveniently.
5. Keeping Reserves and Following Regulations
Commercial banks must keep a certain amount of money as reserves to ensure they can meet customer withdrawals. They are also regulated by the central bank of a country to ensure they operate safely and protect customers’ money.’

How Commercial Banks Make Money
Commercial banks are important financial institutions that provide services such as accepting deposits, giving loans, and facilitating payments. To continue operating and providing these services, commercial banks must generate income. They make money through several activities related to lending, investments, and service charges.
One of the main ways commercial banks make money is through interest on loans. Banks lend money to individuals and businesses for different purposes such as buying homes, starting businesses, or paying for education. When customers borrow money, they are required to repay the loan with interest. The interest charged on loans is usually higher than the interest paid on deposits, and this difference is a major source of profit for banks.
Another way banks earn money is through fees and service charges. Banks charge customers for various services such as maintaining accounts, transferring money, issuing debit or credit cards, using ATMs outside the bank’s network, and processing international transactions. These small charges from many customers add up to significant income for the bank.
Commercial banks also make money through investments. They invest part of their funds in government securities, treasury bills, and other financial instruments. These investments earn interest or returns, which contribute to the bank’s profits.
In addition, banks earn income from foreign exchange services. When customers exchange one currency for another, the bank charges a small margin or fee for the service. This is especially common in international trade and travel.
Banks may also earn money from financial services such as wealth management, insurance services, and advisory services. By helping customers manage their finances or investments, banks can charge commissions or management fees.
