Foreign Exchange Rates: Buying and Selling Currencies & Government Intervention
This section explores the reasons why individuals and institutions buy and sell foreign currencies, as well as the role governments play in influencing exchange rates.
Reasons for Buying and Selling Foreign Currencies
There are several key motivations behind foreign exchange transactions:
International Trade: Businesses involved in importing or exporting goods and services need to convert their domestic currency into the currency of their trading partner to pay for goods or receive payment.
Investment: Investors buy currencies to invest in assets (like stocks, bonds, or real estate) in other countries. The value of these investments can fluctuate with exchange rate changes.
Speculation: Traders buy and sell currencies with the aim of profiting from anticipated changes in exchange rates. This involves assessing economic and political factors that could impact currency values.
Tourism: Travelers need to exchange their domestic currency for the currency of the country they are visiting to cover expenses.
Portfolio Rebalancing: Financial institutions and individuals may buy or sell currencies to adjust their asset allocation and manage risk.
Government Intervention in Currency Markets
Governments and central banks often intervene in foreign exchange markets to influence the value of their currency. The primary goals of such intervention include:
Maintaining Competitiveness: A weaker currency can make a country's exports cheaper and more competitive in international markets.
Controlling Inflation: Interventions can help manage inflation by influencing the value of the currency.
Stabilizing the Economy: Governments may intervene to prevent excessive volatility in exchange rates, which can disrupt economic activity.
Meeting International Obligations: Currency intervention can be used to ensure a country can meet its international debt obligations.

Action
Effect on Currency Value
Buying Domestic Currency
Central bank uses its foreign reserves (e.g., US dollars) to purchase its own currency.
Increases demand for the domestic currency, leading to an appreciation.
Selling Domestic Currency
Central bank sells its domestic currency and buys foreign currencies (e.g., US dollars).
Increases the supply of the domestic currency, leading to a depreciation.
Sterilization
Central bank offsets the effects of currency intervention by conducting open market operations (buying or selling government securities).
Reduces the impact of intervention on the money supply and interest rates.
Factors Influencing Exchange Rates
Several factors can influence the value of a currency:
Interest Rates: Higher interest rates tend to attract foreign investment, increasing demand for the currency and causing it to appreciate.
Inflation: Higher inflation erodes the purchasing power of a currency, leading to depreciation.
Economic Growth: Strong economic growth often leads to currency appreciation as investors are more likely to invest in a growing economy.
Government Debt: High levels of government debt can weaken a currency.
Political Stability: Political instability can deter investment and lead to currency depreciation.
Balance of Payments: A current account surplus (more exports than imports) tends to strengthen a currency, while a current account deficit tends to weaken it.

Understanding foreign exchange rates is crucial for analyzing international trade and globalization. Fluctuations in exchange rates can significantly impact the profitability of businesses and the overall economic well-being of countries.
