Chapter Theme
This chapter provides an overview of the foreign exchange market. It is designed to illustrate (1) why a
market exists, and (2) why exchange rates change over time.
Topics to Stimulate Class Discussion
1. Why did exchange rates change recently?
2. Show the class a current exchange rate table from a periodical—identify spot and forward quotations.
Then show the class an exchange rate table from a date a month ago, or three months ago. The
comparison of tables will illustrate how exchange rates change, and how forward rates of the earlier
date will differ from the spot rate of the future date for a given currency.
3. Make up several scenarios and ask the class how each scenario would, other things equal, affect the
demand for a currency, the supply of a currency for sale, and the equilibrium exchange rate. Then
integrate several scenarios together to illustrate that in reality other things are not held constant,
which makes the assessment of exchange rate movements more difficult.
