Problem Set 2
Modules 3 and 4
1. A one-year long forward contract on a non-dividend-paying stock is entered into
when the stock price is $38 and the risk-free rate of interest is 8% per annum with
continuous compounding.
a) What are the forward price and the initial value of the forward contract?
b) Six months later, the price of the stock is $46 and the risk-free interest rate is
still 8%. What are the forward price and the value of the forward contract?
2. The spot price of oil is $110 per barrel and the cost of storing a barrel of oil for one
year is $3.25, payable at the end of the year. The risk-free interest rate is 6% per
annum, continuously compounded. What is an upper bound for the one-year futures
price of oil?
3. A stock is expected to pay a dividend of $1 per share in two months and in five
months. The stock price is $50, and the risk-free rate of interest is 8% per annum
with continuous compounding for all maturities. An investor has just taken a short
position in a six-month forward contract on the stock.
a) What are the forward price and the initial value of the forward contract?
b) Three months later, the price of the stock is $48 and the risk-free rate of interest
is still 8% per annum. What are the forward price and the value of the short
position in the forward contract?
4. It is May 5, 2013. The quoted price of a government bond with a 12% coupon that
matures on July 27, 2024, is 110-24. What is the cash price?
5. It is July 30, 2015. The cheapest-to-deliver bond in a September 2015 Treasury
bond futures contract is a 13% coupon bond, and delivery is expected to be made
on September 30, 2015. Coupon payments on the bond are made on February 4
and August 4 each year. The term structure is flat, and the rate of interest with
semiannual compounding is 12% per annum. The conversion factor for the bond is
1.5. The current quoted bond price is $110. Calculate the quoted futures price for the
contract.
6. Portfolio A consists of a one-year zero-coupon bond with a face value of $2,000 and
a 10-year zero-coupon bond with a face value of $6,000. Portfolio B consists of a
5.95-year zero-coupon bond with a face value of $5,000. The current yield on all
bonds is 10% per annum.
(a) Show that both portfolios have the same duration.
(b) Show that the percentage changes in the values of the two portfolios for a
0.1% per annum increase in yields are the same.
(c) What are the percentage changes in the values of the two portfolios for a 5%
per annum increase in yields?
7. A financial institution has entered into a 10-year currency swap with company Y.
Under the terms of the swap, the financial institution receives interest at 3% per
annum in Swiss francs and pays interest at 8% per annum in U.S. dollars. Interest
payments are exchanged once a year. The principal amounts are 7 million dollars
and 10 million francs. Suppose that company Y declares bankruptcy at the end of
year 6, when the exchange rate is $0.80 per franc. What is the cost to the financial
institution? Assume that, at the end of year 6, the interest rate is 3% per annum in
Swiss francs and 8% per annum in U.S. dollars for all maturities. All interest rates
are quoted with annual compounding.
8. The LIBOR zero curve is flat at 5% (continuously compounded) out to 1.5 years.
Swap rates for 2- and 3-year semiannual pay swaps are 5.4% and 5.6%,
respectively. Estimate the LIBOR zero rates for maturities of 2.0, 2.5, and 3.0 years.
(Assume that the 2.5-year swap rate is the average of the 2- and 3-year swap rates
and use LIBOR discounting.)
9. A company enters into a total return swap where it receives the return on a corporate
bond paying a coupon of 5% and pays LIBOR. Explain the difference between this
and a regular swap where 5% is exchanged for LIBOR.
10. Assume that the default probability for a company in a year, conditional on no earlier
defaults is and the recovery rate is . The risk-free interest rate is 5% per annum.
R
Default always occur half way through a year. The spread for a five-year plain vanilla
CDS where payments are made annually is 120 basis points and the spread for a
five-year binary CDS where payments are made annually is 160 basis points.
