POINT/COUNTER-POINT:
Should China Be Forced to Alter the Value of Its Currency?
POINT: U.S. politicians frequently suggest that China needs to increase the value of the Chinese yuan
against the U.S. dollar, even since China has allowed the yuan to float (within boundaries). The U.S.
politicians claim that the yuan is the cause of the large U.S. trade deficit with China. This issue is
periodically raised not only with currencies tied to the dollar, but also with currencies that have a floating
rate. Some critics argue that the exchange rate can be used as a form of trade protectionism. That is, a
country can discourage or prevent imports and encourage exports by keeping the value of its currency
artificially low.
COUNTER-POINT: China might counter that its large balance of trade surplus with the U.S. has been due
to the differences in prices between the two countries, and that it should not be blamed for the high U.S.
prices. It might argue that the U.S. trade deficit can be partially attributed to the very high prices in the
U.S., which are necessary to cover the excessive compensation for executives and other employees at U.S.
firms. The high prices in the U.S. encourage firms and consumers to purchase goods from China. Even if
China’s yuan is revalued upward, this does not necessarily mean that the U.S. firms and consumers will
purchase U.S. products. They may shift their purchases from China to purchase products in Indonesia or
other low-wage countries rather than buy more products from the U.S. Thus, the underlying dilemma is not
China, but any country that has lower costs of production than the U.S.

Advanced Questions
16. Monitoring the Fed’s Intervention. Why do foreign market participants monitor the Fed’s direct
intervention efforts? How does the Fed attempt to hide its intervention actions? The media frequently
reports that “the dollar’s value strengthened against many currencies in response to the Federal
Reserve’s plan to increase interest rates.” Explain why the dollar’s value may change even before the
Federal Reserve affects interest rates.
ANSWER: Foreign market participants make investment and borrowing decisions that can be
17. Effects of September 11. Within a few days after the September 11, 2001 terrorist attack on the
U.S., the Federal Reserve reduced short-term interest rates in the U.S. to stimulate the U.S. economy.

dollar? How could such an effect on the dollar increase the probability that the U.S. economy would
strengthen?
ANSWER: The lower interest rates are expected to stimulate the U.S. economy, by encouraging more
18. Intervention Effects on Corporate Performance. Assume you have a subsidiary in Australia. The
subsidiary sells mobile homes to local consumers in Australia, who buy the homes using mostly
borrowed funds from local banks. Your subsidiary purchases all of its materials from Hong Kong. The
Hong Kong dollar is tied to the U.S. dollar. Your subsidiary borrowed funds from the U.S. parent, and
must pay the parent $100,000 in interest each month. Australia has just raised its interest rate in order
to boost the value of its currency (Australian dollar, A$). The Australian dollar appreciates against the
dollar as a result. Explain whether these actions would increase, reduce, or have no effect on:

ANSWER:
19. Pegged Currencies. Why do you think a country suddenly decides to peg its currency to the dollar or
some other currency? When a currency is unable to maintain the peg, what do you think are the typical
forces that break the peg?
ANSWER: A country will usually attempt a peg to reduce speculative flows that occur because of
20. Impact of Intervention on Currency Option Premiums. Assume that the central bank of the country
Zakow periodically intervenes in the foreign exchange market to prevent large upward or downward
fluctuations in its currency (the zak) against the U.S. dollar. Today, the central bank announced that it
would no longer intervene in the foreign exchange market. The spot rate of the zak against the dollar
was not affected by this news. Will the news affect the premium on currency call options that are traded
on the zak? Will the news affect the premium on currency put options that are traded on the zak?
Explain.
21. Impact of Information on Currency Option Premiums. As of 10:00 a.m., the premium on a specific
one-year call option on British pounds is $.04. Assume that the Bank of England had not been
intervening in the foreign exchange markets in the last several months. However, it announces at 10:01
a.m. that it will begin to frequently intervene in the foreign exchange market in order to reduce
fluctuations in the pound’s value against the dollar over the next year, but it will not attempt to push the
pound’s value higher or lower than what is dictated by market forces. Also, the Bank of England has no
plans to affect economic conditions with this intervention. Most participants who trade currency
options did not anticipate this announcement. When they heard the announcement, they expected that

the intervention would be successful in achieving its goal. Will this announcement cause the premium
on the one-year call option on British pounds to increase, decrease, or to be unaffected? Explain.
22. Speculating Based on Intervention. Assume that you expect that the European central bank (ECB)
plans to engage in central bank intervention in which it plans to use euros to purchase a substantial
amount of U.S. dollars in the foreign exchange market over the next month. Assume that this direct
intervention is expected to be successful at influencing the exchange rate.
a. Would you purchase or sell call options on euros today?
b. Would you purchase or sell futures on euros today?
23. Implications of a Fixed Currency for International Trade. Assume the Hong Kong dollar
(HK$) value is tied to the U.S. dollar and will remain tied to the U.S. dollar. Last month, a HK$ =
0.25 Singapore dollars. Today, a HK$=0.30 Singapore dollars. Assume that there is much trade in the
computer industry among Singapore, Hong Kong, and the U.S. and that all products are viewed as
substitutes for each other and are of about the same quality. Assume that the firms invoice their
products in their local currency and do not change their prices.
a. Will the computer exports from the U.S. to Hong Kong increase, decrease, or remain the same?
Briefly explain.
ANSWER: Decrease. The H.K. dollar appreciated against the Singapore dollar while fixed against US
24. Implications of a Revised Peg. The country of Zapakar has much international trade with the
U.S. and other countries, as it has no significant barriers on trade or capital flows. Many firms in
Zapakar export common products (denominated in zaps) that serve as substitutes for products
produced in the U.S. and many other countries. Zapakar’s currency (called the zap) has been pegged at
8 zaps =$1 for the last several years. Yesterday, the government of Zapakar reset the zap’s currency
value so that is now pegged at 7 zaps=$1.
a. How should this adjustment in the pegged rate against the dollar affect the volume of exports by
Zapakar firms to the U.S.?
b. Will this adjustment in the pegged rate against the dollar affect the volume of exports by Zapakar
firms to non-U.S. countries? If so, explain.

c. Assume that the Federal Reserve significantly raises U.S. interest rates today. Do you think

ANSWER:
25. Pegged Currency and International Trade. Assume that Canada decides to peg its currency (the
Canadian dollar) to the U.S. dollar and that the exchange rate will remain fixed. Assume that Canada
commonly obtains its imports from the U.S. and Mexico. The U.S. commonly obtains its imports from
Canada and Mexico. Mexico commonly obtains its imports from the U.S. and Canada. The traded
products are always invoiced in the exporting country’s currency. Assume that the Mexican peso
appreciates substantially against the U.S. dollar during the next year.
a. What is the likely effect (if any) of the peso’s exchange rate movement on the volume of Canada’s
exports to Mexico? Explain.
b. What is the likely effect (if any) of the peso’s exchange rate movement on the volume of Canada’s
exports to the U.S.? Explain.
ANSWER:
26. Impact of Devaluation. The inflation rate in Yinland was 14% last year. The government of Yinland
just devalued its currency (the yin) by 40 % against the dollar. Even though it produces similar types of
products as the U.S., it has much trade with the U.S. and very little trade with other countries. It
presently has trade restrictions imposed on all non-U.S. countries. Will the devaluation of the yin
increase or reduce inflation in Yinland? Briefly explain.
