Introduction
The capital markets across the globe have become one giant playing field– The U.S. share of market capitalization is
steadily declining as foreign markets develop

Foreign Exchange Risk
Introduction FX risk and interest rates The concept of exposure FX risk from a business perspective FX risk from an investment perspective
5
Introduction
Overseas investments and international business involve foreign exchange risk
A survey of corporate treasurers indicates that the primary corporate use of derivative assets is hedging foreign exchange exposure
6
Introduction (cont’d)
Foreign exchange risk is the risk of loss due to changes in the relative value of world currencies– Modest changes in exchange rates can result in
significant dollar differences
7
FX Risk and Interest Rates
Introduction The real rate of interest The inflation premium The risk premium
8
Introduction
Events in one industrial country affect the rest of the world– Interest rates are often a good barometer of
events like high unemployment, changes in economic policy, etc.
9
The Real Rate of Interest
The nominal interest rate (the stated rate) can be expressed as the sum of:– The real rate– An inflation premium and– A risk premium
10
The Real Rate of Interest (cont’d)
The real rate reflects the rate of return investors demand for giving up the current use of funds– Indicates people’s willingness to postpone
spending their money– Is not directly observable– Hovers in the 3% to 4% range
11
The Inflation Premium
The inflation premium reflects how the general price level is changing– Measures how rapidly the money standard is
losing its purchasing power– In the past 75 years, U.S. inflation has averaged
about 3.2% annually
12
The Risk Premium The risk premium is the component of
interest rates that is most difficult to measure– Risk-averse investors expect to be compensated
for risks they take– The price of a risky security must reflect a risk
premium to entice someone to buy it– The magnitude of the risk premium depends on
how much risk the security carries– The higher the risk premium, the lower the price
13
The Concept of Exposure
Introduction Accounting exposure Economic exposure
14
Introduction
Exposure is the extent to which you face foreign exchange risk
There are two general types of exposure:– Accounting exposure– Economic exposure
15
Accounting Exposure
Accounting exposure is the exchange rate exposure that results when consolidated financial statements are prepared in a single currency
Two types of accounting exposure:– Transaction exposure– Translation exposure
16
Accounting Exposure (cont’d)
Transaction exposure results from transactions involving the purchase or sale of goods or services with the price stated in foreign currency– Exists until the payable or receivable is
liquidated– E.g., a U.S. importer must pay a European
supplier in Swiss francs
17
Accounting Exposure (cont’d)
Translation exposure results from translating foreign assets and liabilities into U.S. dollars on the consolidated balance sheet
18
Economic Exposure
Economic exposure measures the risk that the value of a security or a firm will decline due to an unexpected change in relative foreign exchange rates– Would reduce the value of the security or firm– The most important type of exposure for
security investors
19
FX Risk From A Business Perspective
A Business Example of Economic Exposure
An American importer agrees to purchase 400 Swiss overcoats at a price of CHF1,200 each, for a total of CHF480,000. The coats will take 3 months to produce, and the importer is to pay for them upon delivery.
20
FX Risk From A Business Perspective (cont’d)
A Business Example of Economic Exposure (cont’d)
Assume the following exchange rates exist today:
$ per CHF = $0.8073 (direct quotation) CHF per $ = CHF1.2387 (indirect quotation)
21
FX Risk From A Business Perspective (cont’d)
A Business Example of Economic Exposure (cont’d)
If the importer paid for the coats today, each coat would cost the importer:
CHF1,200 x $0.8073/CHF = $968.76The importer is concerned that the U.S. dollar might weaken between now and coat delivery time.
22
FX Risk From A Business Perspective (cont’d)
A Business Example of Economic Exposure (cont’d)
If the dollar strengthens and the value of the Swiss franc falls to $0.7500, the cost of each coat will be:
CHF1,200 x $0.7500/CHF = $900.00If the dollar weakens to an exchange rate of $0.9000, the cost of each coat will be:
CHF1,200 x $0.9000/CHF = $1,080.00
23
FX Risk From An Investment Perspective
An Investment Example of Economic Exposure
You just placed an order with your broker to purchase 10,000 shares of Kangaroo Lager, trading on the Sydney Stock Exchange. You can currently purchase the shares for AUD1.45 apiece.
The current exchange rate is $0.5755/AUD. Thus, the shares cost you:
10,000 x AUD1.45 x $0.5755/AUD = $8,344.75
24
FX Risk From An Investment Perspective (cont’d)
An Investment Example of Economic Exposure (cont’d)
You hold the Kangaroo shares for six months, at which time the shares sell for AUD1.95. This is a return of
(1.95 – 1.45)/1.45 = 34.5%
25
FX Risk From An Investment Perspective (cont’d)
An Investment Example of Economic Exposure (cont’d)
In six months, the exchange rate is $0.5500. If you were to sell the shares, you would receive:
10,000 x AUD1.95 x $0.5500/AUD = $10,725.00
This is a return on investment of
($10,725.00 - $8,344.75)/$8,344.75 = 28.52%
26
Forward Rates
Introduction Purchasing power parity Interest rate parity
27
Introduction
The spot exchange rate is the current exchange rate for two currencies
The forward exchange rate is a contractual rate between a commercial bank and a client for the future delivery of a specified quantity of foreign currency
28
Introduction (cont’d)
Forward exchange rates are normally quoted on the basis of one, two, three, six, and twelve months
29
Introduction (cont’d)
The forward rate is an unbiased estimate of the future spot rate for foreign exchange– E.g., if forward rates show that the dollar is
expected to strengthen against the Swiss franc, it would make sense to delay paying Swiss francs as long as possible
30
Introduction (cont’d)
The difference between the forward and spot rates can be quoted as an annual premium or discount:

Purchasing Power Parity
Purchasing power parity is an arbitrage-based idea that in a world of perfect markets, the same good should sell for the same price in different countries– Assumes there are no trade barriers, no taxes,
etc.
32
Purchasing Power Parity (cont’d)
Unexpected inflation causes the value of the home currency to fall
Differentials in international inflation rates can be a source of foreign exchange risk
33
Interest Rate Parity
Interest rate parity states that differences in national interest rates will be reflected in the currency forward market– Two securities of similar risk and maturity will
show a difference in their interest rates equal to the forward premium or discount, but with the opposite sign
34

Interest Rate Parity (cont’d)
Computing Implied Foreign Interest Rates
It is now January 2, 2004. The six-months forward rate for the British pound is £0.5658/$; the spot rate is £0.5576/$. Also, the six-month T-bill rate is 1.01%.
What is the implied British 6-month interest rate based on the interest rate parity relationship?
36
Interest Rate Parity (cont’d)

The implied British 6-month interest rate is 3.96%:
The actual UK rate in early 2004 was 3.90%.

Foreign Currency Futures
Introduction Pricing of foreign exchange futures
contracts
38
Introduction Foreign currency futures contracts were the
first financial futures traded on exchanges in the U.S.– Began trading at the Chicago Mercantile
Exchange in 1972
Foreign currency futures were quickly recognized as very effective ways to deal with foreign exchange risk
39
Pricing of Foreign Exchange Futures Contracts Futures prices are a function of
– The spot price– The cost of carrying the particular asset or
financial instrument
For foreign currency futures, the cost of holding one currency rather than another is an opportunity cost measured by differences in interest rates

Pricing A Foreign Currency Futures Contract Example
In the Land of Leptonia interest rates are 10.00%, and the current dollar price of a Lepton is $0.4817. The current Eurodollar deposit rate is 7.50%.
For how much should a 90-day futures contract on Lepton’s sell?
42
Pricing of Foreign Exchange Futures Contracts (cont’d)
Pricing A Foreign Currency Futures Contract Example (cont’d)
Using the equation:
The futures price for Leptons should be less than their cost in the spot market. This is because Leptonia’s interest rates are 2.5% higher than the U.S. rate.

Dealing With the Exposure
Introduction Ignore the exposure Reduce or eliminate the exposure Hedge the exposure
44
Introduction
The portfolio manager needs to decide whether to:– Ignore the exposure,– Eliminate the exposure, or– Hedge the exposure
45
Ignore the Exposure Investors may be aware of economic exposure
but accept it as a fact of life
Ignoring the exposure may be appropriate if the dollar amount of the exposure is relatively small
Ignoring the exposure may be appropriate if the dollar is expected to depreciate
46
Reduce or Eliminate the Exposure
Amounts to selling the foreign security or reducing the size of the position
May be appropriate if the dollar is expected to appreciate dramatically
47
Hedge the Exposure
Involves taking a position in the market that offsets another position– Hedging foreign exchange risk is also called
covering the risk– Hedging can be done in the forward market or
the futures market
