Understanding Currency Value Changes in Exchange Rate Systems

The question asks about a specific term used when the value of a domestic currency decreases relative to a foreign currency within a fixed exchange rate system.

Exchange Rate Systems Explained

There are primarily two types of exchange rate systems:

• Floating (or Flexible) Exchange Rate System: The value of a currency is determined by market forces of supply and demand.
• Fixed (or Pegged) Exchange Rate System: The government or central bank officially sets and maintains the exchange rate at a specific level against another currency or a basket of currencies.

Changes in Currency Value

The terms used to describe changes in a currency's value depend on the exchange rate system:

• In a Floating System:
  • A decrease in currency value is called Depreciation.
  • An increase in currency value is called Appreciation.
• In a Fixed System:
  • A decrease in currency value is called Devaluation. This is a deliberate action taken by the monetary authority.
  • An increase in currency value is called Revaluation. This is also a deliberate action taken by the monetary authority.

Let's look at the options provided:

• Depreciation: This refers to a decrease in currency value in a floating exchange rate system. The question specifies a fixed system.
• Devaluation: This refers to a decrease in currency value in a fixed exchange rate system, usually implemented by the government or central bank. This matches the conditions in the question.
• Appreciation: This refers to an increase in currency value in a floating exchange rate system. The question asks about a decrease.
• Revaluation: This refers to an increase in currency value in a fixed exchange rate system. The question asks about a decrease.

Based on the definitions, a decrease in the value of domestic currency relative to foreign currency in a fixed exchange rate system is specifically termed Devaluation.

Why Devaluation is the Correct Term

The question is very specific about the context: a fixed exchange rate system. In such a system, the official value of the currency is set and maintained by the central bank or government. When this authority decides to lower the official value of the domestic currency against other currencies, this action is called Devaluation. It is a policy decision, not a result of market forces like depreciation in a floating system.

Therefore, the correct term for a decrease in the value of domestic currency to foreign currency in a fixed exchange rate system is Devaluation.

Additional Information: Effects of Devaluation

Devaluation can be used by a country to address economic imbalances, particularly in international trade. Some potential effects of devaluation include:

• Boosting Exports: When the domestic currency is devalued, domestic goods become cheaper for foreign buyers, which can increase demand for exports.
• Discouraging Imports: Foreign goods become more expensive for domestic buyers, which can reduce demand for imports.
• Improving Trade Balance: If the increase in exports and decrease in imports are significant enough, it can help improve a country's balance of trade deficit.
• Increasing Inflation: Imported goods becoming more expensive can lead to higher domestic prices.
• Attracting Tourism: The country becomes a cheaper destination for foreign tourists.
• Impact on Foreign Debt: Debt denominated in foreign currency becomes more expensive to repay in terms of the devalued domestic currency.

Understanding whether a currency change occurs in a fixed or floating system is crucial for using the correct terminology (Depreciation/Appreciation vs. Devaluation/Revaluation).
