Explanation:
Banks pay interest on customer deposits. It means that a customer's deposit will grow if left at the banks for some period. When a customer deposits, the bank retains only a small fraction of the money in its custody. The bigger portion is loaned out to other customers. Therefore, a bank uses customer deposits to create loans. In return, the banks will pay customers interest for the use of their deposits. Banks also charge interest when they loan out money.
