2. FOREX
• Functions of the Foreign Exchange
Market
• Convert the currency of one country
into the currency of another
• Provide some insurance against
foreign exchange risk

3. Currency Conversion
• In general, within the borders of a particular country, one must use the
national currency.
• Businesses use the foreign exchange market
• To convert the payments received for its exports, the income received from foreign
investments, or the income received from licensing agreements with foreign firms
• To make payment to a foreign company for its products or services in its country’s
currency
• To invest cash for short terms in foreign money markets
• For currency speculation
• Carry trade
5. Forward Exchange Rate
• In an AUD/SGD example:
• Home currency = SGD
Foreign currency = AUD
1Yr Home Interest Rate = 1%
1 Yr Foreign Interest Rate = 3%
Current Exchange Rate = $1.50
Therefore, 1 Yr Forward Rate = (1.01)/(1.03) x
1.50= 1.47

6. Insuring Against Foreign Exchange Risk
Currency swaps
Transaction between
international businesses and
their banks, between banks,
and between governments
Common type: spot against
forward

8. Prices and Exchange Rates
• The law of one price
• Purchasing power parity
• Comparison of prices of
identical products
determine the real or
PPP exchange rate
• The price of a “basket of
goods” should be
roughly equivalent in
each country
• Big Mac Index

9. Prices and Exchange Rates
• Money supply and price inflation
• The growth rate of a country’s money
supply determines its likely future
inflation rate.
• Inflation -- money supply increases
faster than output increases.
• An increase in the money supply
makes it easier to borrow, which
increases demand for goods and
services.
• A country with a high inflation rate will
see depreciation in its currency
exchange rate.
• Government policy determines growth
rates.

10. Prices and Exchange Rates
Empirical tests of PPP theory
• Exchange rates are determined by relative prices and changes
in relative prices will result in a change in exchange rates.
• Not a strong predictor of short-run movements in exchange
rates covering time spans of five years or less
• Best predicts exchange rate changes for countries with high
rates of inflation and underdeveloped capital markets
11. Interest Rates and Exchange Rates
• Interest rates reflect expectations
about likely future inflation rates
• The Fisher effect
• 𝑖 = 𝑟 + 𝐼
• If the real interest rate is the same
worldwide, any difference in interest
rates between countries reflects
differing expectations about inflation
rates
• The international Fisher
effect (IFE)

12. Investor Psychology and Bandwagon Effects
• Neither PPP theory nor the
international Fisher effect is
particularly good at explaining
short-term movements in
exchange rates.
• Investor psychology
• Bandwagon effect

13. Summary of Exchange Rate Theories
• Relative monetary growth, relative
inflation rates, and nominal interest
rate differentials are all moderately
good predictors of long-run changes
in exchange rates.
• But they are poor predictors of short-
run changes.

14. Efficient vs Inefficient Market Schools
The Efficient Market School
• Prices reflect all available public
information
• Forward exchange rates should
be unbiased predictors of
future spot rates
The Inefficient Market School
• Prices do not reflect all available
information.
• Forward exchange rates will not be
the best possible predictors of
future spot exchange rates
15. Approaches to Forecasting
• Fundamental Analysis
• Draws on economic theory to
construct sophisticated
econometric models for predicting
exchange rate movements
• Includes relative money supply
growth rates, inflation rates, and
interest rates, and possibly
balance-of-payments positions
• Technical Analysis
• Uses price and volume data to
determine past trends, which are
expected to continue into the
future
• There are analyzable market
trends and waves that can be used
to predict future trends and waves

16. Currencies can be…
• Freely convertible
• Externally convertible
• Nonconvertible
• Not desirable for international
business
Governments limit
convertibility to preserve their
foreign market reserves.
• Capital flight
• Countertrade
