21. The cash price of a $1,000 bond that paid coupons semi-annually with a coupon rate of 7% p.a. that matures in exactly 18 months is $1,017.34.

22. On June 1, the treasurer of a US firm decides to hedge the planned issue of corporate bonds against further interest rate increases. On current forward interest rates, the August bond issue would realise $1.89 million. The bonds would have a total face value of $2.0 million and a duration of 6.6 years. The September Treasury bond futures price is currently 94-08 and the cheapest-to-deliver bond will have a duration of 8.7 years at maturity. How should the treasurer hedge against changes in interest rates over the next two months?
[Note: T-bond futures have $100,000 face value.] [12.5 marks]

23. Assume the only carrying cost associated with gold is the interest rate, which remains unchanged at 10% p.a. (continuous compounded) for all maturities. Suppose that on March 16th 2012, Jill had entered into a one-year short forward contract to sell 100 ounces of gold for USD1,700.00/oz. If three months later (June 16th, 2012), she observed that the spot price of gold was USD1,838.00/oz, what would be the value of her position on this date?

24. The five-month S&P500 share price index (SPI) futures price is 1,400 points. If the continuously compounded dividend yield on the SPI is 3.0% p.a. and the risk-free rate of interest is 1.3% p.a. with continuous compounding for all maturities, what will be the no-arbitrage value of the two-month index futures contract?
