Foreign Exchange Market Overview

Market for converting the currency of one country into that of another country.
Exchange rate: the rate at which one currency is converted into another.
Future exchange rates cannot be accurately predicted.
The foreign exchange market provides some insurance against foreign exchange risk.

Functions of the Foreign Exchange Market

1. Currency Conversion

Within the borders of a country, national currency is primarily used.
Businesses utilize the foreign exchange market to: - Convert payments received for exports, income from foreign investments, or income from licensing agreements with foreign firms. - Make payments to foreign companies for their products or services using the foreign firm's currency. - Invest cash for short terms in foreign money markets. - Engage in currency speculation.

Carry Trade

Involves borrowing in a currency with a low-interest rate and investing in a currency with a higher interest rate.

2. Insuring Against Foreign Exchange Risk

Spot Exchange Rates

The rate at which a foreign exchange dealer converts one currency into another on a specific day.
Change frequently, with their value influenced by supply and demand.

Forward Exchange Rates

A forward exchange rate is an agreement between two parties to exchange currencies at a fixed rate at a specific date in the future.
Typically quoted for future dates such as 30, 90, and 180 days.

Currency Swaps

Involves simultaneous purchase and sale of a specified amount of foreign exchange for two different value dates.
Transactions occur between international businesses and their banks, other banks, and governments.
A common type of swap is a spot against forward.

Nature of the Foreign Exchange Market

1. Market Characteristics

A global network of banks, brokers, and foreign exchange dealers connected via electronic communication.
Rapidly growing market with significant trading centers such as: - London (largest) - New York - Zurich - Tokyo - Singapore

2. Transaction Insights

In 2022, approximately 88% of all foreign exchange transactions involved the US dollar on one side.
Other important vehicle currencies: - Euro: 31% - Japanese Yen: 17% - British Pound: 13%

Market Availability

The foreign exchange market operates 24/7, allowing for continuous trading.
Arbitrage opportunities exist: buying securities in one market for immediate resale in another market due to price discrepancies.

Economic Theories of Exchange Rate Determination

1. Prices and Exchange Rates

Law of One Price

In competitive markets free of transportation costs and trade barriers, identical products must sell for the same price when expressed in the same currency.

Purchasing Power Parity (PPP)

Real or PPP exchange rates are determined by comparing prices of identical products across countries.
Assumes an efficient market without trade impediments, leading to equivalent prices for a “basket of goods.”
Example: The Big Mac Index uses the price of a Big Mac to measure currency valuation.
Formula: - E_{$/¥} = rac{P_{}}{P_{¥}}

2. Money Supply and Inflation Impact

Money supply growth rate impacts future inflation rate predictions.
Inflation occurs when money supply increases faster than output. This can lead to currency depreciation.
Hyperinflation is rapid price inflation where the currency loses value quickly.

3. Empirical Testing of PPP Theory

Exchange rates are influenced by relative prices; changes in these prices can impact exchange rates.
PPP theory proves accurate long-term but fails to predict short-term movements well, particularly over five years or less.
Better predictive ability found in countries with high inflation and underdeveloped capital markets.

Purchasing Power Parity Puzzle

Reasons for Failure:

Assumes no transportation costs or trade barriers.
Prices can deviate due to price discrimination.
Government interventions may affect currency values.

4. Interest Rates and Exchange Rates

Fisher Effect

Indicates that differences in interest rates reflect expectations about future inflation rates if real interest rates are consistent worldwide.

International Fisher Effect (IFE)

Suggests that currency values change as a function of interest rates and expected inflation, impacting future exchange rates.

5. Investor Psychology and Bandwagon Effects

Both PPP and IFE explanations fall short in predicting short-term exchange rate movements.
Investor psychology can drive fluctuations in exchange rates through herd behavior (bandwagon effect).

6. Summary of Exchange Rate Theories

Relative monetary growth, inflation rates, and nominal interest rate differentials moderately predict long-term exchange rate changes but poorly predict short-term fluctuations.

Exchange Rate Forecasting

1. Efficient Market School

An efficient market reflects all available public information, where forward exchange rates serve as unbiased predictors of future spot rates.
Inaccuracies in predictions are considered random.

2. Inefficient Market School

An inefficient market does not fully reflect all available information, meaning forward exchange rates may not accurately predict future spot rates.

3. Forecasting Approaches

Fundamental Analysis

Utilizes economic theory to create models predicting exchange rate movements, incorporating: - Money supply growth rates - Inflation rates - Interest rates - Balance-of-payments positions.

Technical Analysis

Analyzes past price and volume data to detect trends that may continue in the future.
Has garnered increased favor among analysts.

Currency Convertibility

Forms of Currency Convertibility

Freely Convertible: Both residents and nonresidents can purchase unlimited foreign currency.
Externally Convertible: Only residents can convert domestic currency to foreign currency without restrictions.
Nonconvertible: No conversion of domestic currency allowed.

Limiting Convertibility

Governments may restrict currency convertible to safeguard foreign exchange reserves.
Capital Flight: Occurs when investors rush to convert domestic currency into foreign currency, usually driven by rapid devaluation of the domestic currency.
Companies may engage in countertrade as a workaround, using barter-like agreements to manage nonconvertibility.

Managerial Implications

1. Foreign Exchange Rate Risk

Transaction Exposure

The extent to which income from individual transactions is affected by fluctuations in foreign exchange rates.

Translation Exposure

The effect of currency exchange rate changes on a company’s financial statements.

Economic Exposure

The degree to which a firm’s future earning power is impacted by changes in exchange rates.

2. Reducing Translation and Transaction Exposure

Strategies include: - Forward exchange rate contracts. - Currency swaps. - Lead Strategy: Collect foreign currency receivables early. - Lag Strategy: Delay collection of foreign currency receivables until more favorable rates.

3. Reducing Economic Exposure

Distribute the firm’s assets across various locations to mitigate adverse impacts of exchange rate changes on long-term financial health.

4. Additional Steps for Managing Foreign Exchange Risk

Implement centralized control over exposure for efficient resource protection and proper strategy execution.
Differentiate between transactions, translation, and economic exposures for better management.
Forecast future exchange rate movements accurately to prepare.
Establish robust reporting systems for regular monitoring of exposure positions.
Generate monthly reports on foreign exchange exposures for management review.
