Call Money

Call money is short term finance repayable on demand, with a maturity period of one day to fifteen days, used for inter-bank transactions. Commercial banks have to maintain a minimum cash balance known as cash reserve ratio. The Reserve Bank of India changes the cash reserve ratio from time to time which in turn affects the amount of funds available to be given as loans by commercial banks. Call money is a method by which banks borrow from each other to be able to maintain the cash reserve ratio. The interest rate paid on call money loans is known as the call rate.
