3. Chapter 4 Objectives This chapter will:
A. Explain how exchange rate movements are measured
B. Explain how the equilibrium exchange rate is determined
C. Examine factors that determine the equilibrium exchange rate

4. A. Measuring Exchange Rate Movements
1. Basic Movements in Rates
-when one currency depreciates against another, the other must appreciate.
Let St-1 = the original rate
S = the current rate
a. Appreciation
b. Depreciation

5. B. Exchange Rate Equilibrium
How exchange rates reach equilibrium?
1. Demand for a Currency
a. derived from the local buyers who are willing and able to purchase foreign goods but who must convert their local currencies.
b. An indirect relationship exists between the cost of foreign currency and amount demanded.
c. Graphically, a downward-sloping demand curve

6. Demand Schedule for British Pounds

7. B. Exchange Rate Equilibrium
2. Supply of a Currency for Sale
a. derived from the foreigners who are willing and able to supply foreign currency that must be converted first in order to purchase local goods.
b. A direct relationship exists between cost of the foreign currency and the amount supplied.
c. Graphically, an upward-sloping supply curve

9. B. Exchange Rate Equilibrium

10. Equilibrium Exchange Rate Determination
Exhibit 4.4 page 89

11. C. Factors That Influence Exchange Rates
1. Relative Inflation Rates
2. Relative Interest Rates
a. Real Interest Rates
3. Relative Income Levels

12. D. Government Controls
Governments influence the equilibrium exchange rate in many ways, including
1. imposing foreign exchange barriers,
2. imposing foreign trade barriers,
3. intervening (buying and selling currencies) in the foreign exchange markets,
4. affecting macro variables such as inflation, interest rates, and income levels.

13. E. Expectations 1. The Role of Information
a. Impact of Signals on Currency Speculation
1.) commonly driven by signals of future interest rate movements
2.) by other factors such as
signals of the future economic conditions that affect exchange rates

14. 2. Interaction of Factors

15. F. Speculating on Anticipated Exchange Rates
Many commercial banks attempt to capitalize on their forecasts of anticipated exchange rate movements in the foreign exchange market
