Suppose the December CBOT Treasury bond futures contract has a quoted price of 80-07. If annual interest rates go up by 1.00 percentage point, what is the gain or loss on the futures contract? Assume this contract is based on a 20 year Treasury bond with semi-annual interest payments. The face value of the bond is $1000, and the semi-annual coupon payments are $30. The annual coupon rate on the bonds is $60 per bond (or 6%). The futures contract has 100 bonds.
