Introduction Exchange rates are important because they enable us
to translate different counties’ prices into comparable terms. Exchange rates are determined in the same way as other asset prices. The general goal of this chapter is to show:
• How exchange rates are determined • The role of exchange rates in international trade

Slide 13-1
Exchange Rates and International Transactions Domestic and Foreign Prices • If we know the exchange rate between two countries’ currencies, we can compute the price of one country’s exports in terms of the other country’s money. – Example: The dollar price of a £50 sweater with a dollar exchange rate of $1.50 per pound is (1.50 $/£) x (£50) = $75.

Slide 13-2
Exchange Rates and International Transactions • Two types of changes in exchange rates: – Depreciation of home country’s currency – A rise in the home currency prices of a foreign currency – It makes home goods cheaper for foreigners and foreign goods more expensive for domestic residents.
– Appreciation of home country’s currency – A fall in the home price of a foreign currency – It makes home goods more expensive for foreigners and foreign goods cheaper for domestic residents.

Slide 13-3
Exchange Rates and International Transactions Exchange Rates and Relative Prices • Import and export demands are influenced by relative prices. • Appreciation of a country’s currency: – Raises the relative price of its exports – Lowers the relative price of its imports
• Depreciation of a country’s currency: – Lowers the relative price of its exports – Raises the relative price of its imports

The Foreign Exchange Market Exchange rates are determined in the foreign exchange market.
• The market in which international currency trades take place
The Actors • The major participants in the foreign exchange market are:
– Commercial banks – International corporations – Nonbank financial institutions – Central banks Copyright © 2003 Pearson Education, Inc.
Slide 13-5
Exchange Rates and International Transactions • Interbank trading – Foreign currency trading among banks – It accounts for most of the activity in the foreign exchange market.

Slide 13-6
Exchange Rates and International Transactions Spot Rates and Forward Rates • Spot exchange rates – Apply to exchange currencies “on the spot”
• Forward exchange rates – Apply to exchange currencies on some future date at a prenegotiated exchange rate
• Forward and spot exchange rates, while not necessarily equal, do move closely together.

Slide 13-7
Exchange Rates and International Transactions Foreign Exchange Swaps • Spot sales of a currency combined with a forward repurchase of the currency. • They make up a significant proportion of all foreign exchange trading.

Slide 13-8
Exchange Rates and International Transactions Futures and Options • Futures contract – The buyer buys a promise that a specified amount of foreign currency will be delivered on a specified date in the future.
• Foreign exchange option – The owner has the right but not obligation to buy or sell a specified amount of foreign currency at a specified price.
