Why do banks keep a small proportion of the deposits as cash with themselves?
1:Banks keep a small proportion of their deposits as cash with themselves. This is usually 15%
of their deposits as cash. This amount is kept as a provision to pay the
depositors who may come to withdraw the money on any day. This amount is enough
because only a small fraction of people come to withdraw money on a given day.
2:The rest of the amount is used by the banks to give money on credit to people
who need the credit. A bank charges interest on the loan which it gives to its
creditors. The interest rate charged by a bank with no loans is higher than the
interest rate given by it on deposits. Thus, interest is the main source of
income for banks.
