35. Speculating with Currency Options. Barry Egan is a currency speculator. Barry believes that the
Japanese yen will fluctuate widely against the U.S. dollar in the coming month. Currently, one-month
call options on Japanese yen (¥) are available with a strike price of $.0085 and a premium of $.0007
per unit. One-month put options on Japanese yen are available with a strike price of $.0084 and a
premium of $.0005 per unit. One option contract on Japanese yen contains 6.25 million yen. (See
Appendix B in this chapter.)
a. Describe how Barry Egan could utilize these options to speculate on the movement of the
Japanese yen.
b. Assume Barry decides to construct a long strangle in yen. What are the break-even points of this
strangle?
c. What is Barry’s total profit or loss if the value of the yen in one month is $.0070?

40. Uncertainty and Option Premiums. At 10:30 a.m., the media reported news that the Mexican
government‘s political problems had decreased, which reduced the expected volatility of the Mexican
peso against the dollar over the next month. The spot rate of the Mexican peso was $.13 as of 10 a.m.
and remained at that level all morning. At 10 a.m., Hilton Head Co. purchased a call option at the
money on 1 million Mexican pesos with an expiration date one month from now. At 11:00 a.m.,
Rhode Island Co. purchased a call option at the money on 1 million pesos with a December expiration
date one month from now. Did Hilton Head Co. pay more, less, or the same as Rhode Island Co. for
the options? Briefly explain.
41. Speculating with Currency Futures. Assume that one year ago, the spot rate of the British pound
was $1.70, and the one-year futures contract of the British pound exhibited a discount of 6%. At that
time, you sold futures contracts on pounds, representing a total of 1,000,000 pounds. From one year
ago to today, the pound’s value depreciated against the dollar by 4 percent. Determine the total dollar
amount of your profit or loss from your futures contract.
ANSWER: Spot rate 1 year ago = $1.70
42. Speculating with Currency Options. The spot rate of the New Zealand dollar is $.77. A call option
on New Zealand dollars with a one-year expiration date has an exercise price of $.78 and a premium
of $.04. A put option on New Zealand dollars at the money with a one-year expiration date has a
premium of $.03. You expect that the New Zealand dollar’s spot rate will decline over time and will
be $.71 in one year.

response to this announcement, the expected volatility of the A$ declined immediately. However, the
Currency Derivatives 23
spot rate of the A$ remained at $.89 on this day and was not affected by the announcement. Likewise,
the one-year forward rate of the A$ remained at $.89 on this day and was not affected by the
announcement. Do you think the premium charged on a one-year A$ currency option increased,
decreased, or remained the same on this day in response to the announcement? Briefly explain.
CRITICAL THINKING
Pricing of Currency Options Review the logic regarding how currency options are priced. Consider a
speculator who plans to purchase currency options for the option at the money on whatever currency has
the lowest premium. He also who plans to sell currency options for the option at the money on whatever
currency has the highest premium. Another speculator uses a strategy of purchasing call options on
Australian dollars at the money whenever the premium is relatively low (compared to the historical
premiums that existed for this type of option) and sells call options at the money on Australian dollars at
the money. Write a short essay describing your opinion about the likely success of these strategies.
ANSWER
The premium charged for currency options that are at the money are highly influenced by the implied
Solution to Continuing Case Problem: Blades, Inc.

the two months between the order and delivery dates by either buying or selling yen futures now and
buying or selling yen at the future spot rate. Given this information, what is the expectation regarding
the order date of the yen spot rate by the delivery date? (Your answer should consist of one number.)

movement, then the expectation of the future spot rate would be equal to the futures rate. For

question 3 and given that the decision is made solely on a cost basis, is to purchase one futures
5. Will the choice you made as to the optimal hedging strategy in question 4 definitely turn out to be the
lowest-cost alternative in terms of actual costs incurred? Why or why not?

incurred may turn out to be lower had the firm employed either an option to hedge the yen payable or

Solution to Supplemental Case: Capital Crystal, Inc.
This case is designed to give students more insight on the advantages and disadvantages of currency
futures and options. More comprehensive questions on this subject are offered in Chapter 11.
a. To hedge with futures, the cost of the imports will be $795 million ($1.59 × £500 million). To hedge
with call options, the cost per unit (including the premium paid) is $1.61, so that the cost of the
b. Since the future spot rate is likely to exceed the futures price, hedging with futures would likely be less
costly than not hedging. Even if it was more costly, it might be wise to hedge in keeping with the
conservative management style of Capital Crystal, Inc.

hedged with a call option. This issue normally generates much discussion. The key question is
whether a manager should take the risk of not hedging. While this strategy is expected to save the firm
$5 million, it could backfire if the pound appreciates over the period (in which case the manager may
be reprimanded). This part of the case attempts to show that hedging is sometimes used even if it is
expected to be more costly than not hedging, because of the desire to avoid risk.
If students put themselves in the position of the managers (bonus is received if a minimum level of
performance is achieved), they would probably hedge. However, it is questionable whether this
strategy would satisfy shareholder wealth. One could argue that there are agency problems, because
managers are forced by the bonus system to avoid risk. Therefore, managers may use more
conservative strategies than what is desired by shareholders in some situations.
This case is realistic, although the name of the firm has been changed. The manager decided to use the
call options in order to avoid risk; based on the firm’s policy, he would not have benefited directly by
not hedging even if it reduced the firm’s costs. There was no real incentive to take any chances.

ANSWER: Jim may consider purchasing put options, which provide a greater degree of flexibility.
The option provides a hedge if the pound depreciates but does not need to be exercised if the pound
appreciates.
The disadvantage of purchasing put options is that a premium must be paid to purchase the options,
whereas such a premium would not have to be paid when using futures contracts to hedge.
Part 1Integrative Problem
The International Financial Environment
Mesa Company specializes in the production of small fancy picture frames, which are exported from the
U.S. to the United Kingdom. The firm invoices the exports in pounds and then converts the pounds to
dollars when they are received. The British demand for these frames is positively related to economic
conditions in the United Kingdom. Assume that British inflation and interest rates are similar to the rates
in the U.S. Mesa believes that the U.S. balance-of-trade deficit from trade between the U.S. and the
United Kingdom will adjust to changing prices between the two countries, while capital flows will adjust
to interest rate differentials. Mesa believes that the value of the pound is very sensitive to changing
international capital flows and is moderately sensitive to international trade flows. Mesa is considering
the following information:
The U.K. inflation rate is expected to decline, whereas U.S. inflation rate is expected to rise.
British interest rates are expected to decline, whereas U.S. interest rates are expected to increase.
1. Explain how the international trade flows should initially adjust in response to the changes in inflation
(holding exchange rates constant). Explain how the international capital flows should adjust in
response to the changes in interest rates (holding exchange rates constant).
2. Based on the information provided, will Mesa expect the pound to appreciate or depreciate in the
future? Explain.

3. Mesa believes international capital flows shift in response to changing interest rate differentials. Is
there any reason why the changing interest rate differentials in this example will not necessarily cause
international capital flows to change significantly? Explain.
4. Based on your answer to question 2, how would Mesa’s cash flows be affected by the expected
exchange rate movements? Explain.
5. Based on your answer to question 4, should Mesa consider hedging its exchange rate risk? If so,
explain how it could hedge using forward contracts, futures contracts, and currency options.
