Commercial banks are referred to as financial intermediaries because they serve as a crucial link between savers and borrowers in an economy. In every society, some individuals, businesses, and institutions have surplus funds that they want to save safely, while others need funds for consumption, investment, or business expansion. Commercial banks stand between these two groups by collecting surplus money from savers in the form of deposits and lending it to borrowers who require capital. For example, a salaried employee deposits part of their monthly income in a savings account, and the bank later uses that money to provide a loan to a small entrepreneur to start or expand a business. In this way, banks ensure that money does not remain idle and flows productively within the economy.
One of the main reasons commercial banks are known as financial intermediaries is their role in mobilizing savings. People deposit money in banks through savings accounts, fixed deposits, and recurring deposit schemes because banks provide safety, liquidity, and interest. Although individual deposits may be small, banks pool together thousands of such deposits to create large financial resources. For instance, if many individuals deposit Tk 2,000 each month in recurring deposit accounts, the bank can combine these funds and provide a sizeable loan to a manufacturing firm. This process transforms scattered and idle savings into productive capital that supports economic activities.
Commercial banks further strengthen their intermediary role by providing credit to borrowers. The funds collected from depositors are transferred to individuals, businesses, and government institutions in the form of loans and advances. These loans can be used for various purposes, including business expansion, industrial development, education, housing, or agriculture. For example, a student may take an education loan to pursue higher studies, or a farmer may receive an agricultural loan to buy seeds and equipment. By transferring money from those who do not need it immediately to those who can use it productively, banks promote investment, employment generation, and economic growth.
Another important aspect of financial intermediation performed by commercial banks is the transformation of risk and maturity. Depositors generally prefer their money to be safe and easily withdrawable, while borrowers often need funds for longer periods and are willing to pay interest. Commercial banks manage this difference by maintaining cash reserves and lending to multiple borrowers. For example, while a depositor may withdraw money from a savings account at any time, a bank may provide a five- or ten-year loan to a housing project by carefully managing its overall funds. This allows depositors to enjoy liquidity and safety, while borrowers gain access to long-term financing.
In addition, commercial banks facilitate the efficient circulation of money through payment and settlement services, including cheques, electronic fund transfers, online banking, and mobile banking. These services support the intermediary role by ensuring that money moves smoothly between different sectors of the economy. For example, a business can pay suppliers through online banking, and a parent can transfer tuition fees to a child studying in another city without using cash. Therefore, commercial banks are referred to as financial intermediaries because they connect savers with borrowers, mobilize and allocate financial resources efficiently, manage risk, and contribute to economic stability and development.
