A financial firm plans to borrow $75 million in the money market at a current interest rate of 4.5 percent. However, the borrowing rate will float with market conditions. To protect itself the firm has purchased an interest-rate cap of 5 percent to cover this borrowing. If money market interest rates on these funds suddenly climb to 5.5 percent as the borrowing begins, how much in total interest will the firm owe and how much of an interest rebate will it receive assuming the borrowing is only for one month?
