Introduction

Chapter 8 discusses the factors that influence exchange rates in foreign exchange markets. Understanding the determinants of exchange rates is crucial for businesses, investors, and policymakers as it helps to predict and analyze currency movements. This chapter will explore various factors that contribute to the fluctuations of exchange rates, providing insights into how supply and demand in foreign exchange markets are influenced.

Factors Influencing Exchange Rates

Exchange rates are determined by a complex interplay of various economic, financial, and geopolitical factors. Some of the key determinants of exchange rates include:

• Interest Rates: Central banks’ monetary policies, particularly changes in interest rates, have a significant impact on exchange rates. Higher interest rates in a country attract foreign investors seeking better returns, leading to an increased demand for the country’s currency and consequently an appreciation of that currency.

• Inflation Rates: Countries with lower inflation rates tend to experience currency appreciation as their purchasing power increases relative to other countries. Conversely, high inflation can lead to depreciation as the domestic currency’s value erodes.

• Economic Growth and Stability: Strong economic growth and stable economic conditions in a country can attract foreign investment and increase demand for its currency, resulting in currency appreciation.

• Trade Balance: A country’s trade balance (exports minus imports) affects its exchange rate. A trade surplus (more exports than imports) can lead to currency appreciation, while a trade deficit can lead to depreciation.

• Political Stability and Economic Policies: Political stability and favorable economic policies attract foreign investment, leading to an increase in demand for the country’s currency and appreciation.

• Speculation and Market Sentiment: Market participants’ expectations and speculative activities can influence short-term exchange rate movements.

Supply and Demand in Foreign Exchange Markets

The exchange rate is determined by the interaction of supply and demand for currencies in foreign exchange markets. If there is high demand for a particular currency, its value relative to other currencies will increase. Conversely, if there is an oversupply of a currency, its value will decrease.

Example: Suppose there is a surge in demand for Japanese yen by international investors seeking to invest in Japanese stocks. This increased demand for yen will lead to an appreciation of the yen’s value relative to other currencies.

Exchange Rate Regimes

Countries adopt different exchange rate regimes, which can also impact exchange rate movements. Some common exchange rate regimes include fixed, floating, managed, and pegged exchange rates.

Example: In a fixed exchange rate regime, a country’s central bank keeps the exchange rate fixed relative to a specific currency (e.g., the U.S. dollar). This means that the central bank intervenes in the foreign exchange market to maintain the fixed rate, even if it requires buying or selling its currency.
