A mutual fund plans to purchase $500,000 of 30-year Trea- sury bonds in four months. These bonds have a duration of 12 years and are priced at 96-08 (32nds). The mutual fund is concerned about interest rates changing over the next four months and is considering a hedge with T-bond futures con- tracts that mature in six months. The T-bond futures con- tracts are selling for 98-24 (32nds) and have a duration of 8.5 years. (LG 23-2)

b. How many contracts should be used?

c. If the implied rate on the deliverable bond in the futures market moves 12 percent more than the change in the discounted spot rate, how many futures contracts should be used to hedge the portfolio?

d. What causes futures contracts to have a different price sensitivity than the assets in the spot markets?
