Commercial banks are key depository institutions that accept deposits and make loans. They play an important role in the economy by mobilizing savings, facilitating credit creation, and supporting agricultural, industrial and economic development. Commercial banks primarily accept deposits and advance loans. They obtain funds from deposit accounts like demand deposits, savings accounts, and time deposits, as well as borrowed funds from the central bank, repurchase agreements, and bonds. Banks then use these funds for cash reserves, lending activities, investing in securities, and other purposes.
