Understanding Floating Exchange Rates

A floating exchange rate system is one where the value of a country's currency is determined by the forces of supply and demand in the foreign exchange market. Unlike a fixed exchange rate where the government or central bank sets and maintains the rate, a floating rate is constantly changing based on market conditions.

Analyzing Statements on Floating Exchange Rate Determination

Let's carefully examine each statement provided in the question regarding what determines a floating exchange rate:

• Statement (A): Floating exchange rate is determined by supply and demand of Dollar only.

  This statement is incorrect. While the U.S. dollar is a major currency, its exchange rate with another currency (say, the Euro) is determined by the supply and demand for *both* the dollar and the Euro in the foreign exchange market. Focusing only on the dollar's supply and demand without considering the other currency is incomplete.

• Statement (B): Floating exchange rate is determined by supply of the particular currency.

  This statement is incorrect. The value of a currency is determined by the interaction of *both* its supply and the demand for it relative to another currency. Just the supply alone does not set the exchange rate.

• Statement (C): Floating exchange rate is determined by the total stock of gold reserve.

  This statement is incorrect. The total stock of gold reserves was relevant in historical systems like the gold standard, which was a type of fixed exchange rate system. In a modern floating exchange rate system, gold reserves do not directly determine the currency's value.

• Statement (D): Floating exchange rate is determined by the demand for the particular currency.

  This statement is incorrect. Similar to Statement (B), the value of a currency is set by the balance of *both* its supply and the demand for it in the foreign exchange market. Considering only demand is insufficient.

• Statement (E): Floating exchange rate is determined by the relative supply and demand of the currencies.

  This statement is correct. The exchange rate between two currencies in a floating system is established at the point where the quantity of one currency supplied equals the quantity of the other currency demanded at that specific rate, and vice-versa. It's the balance of supply and demand for *both* currencies in the pair that matters.

Determining the Correct Statement

Based on the analysis, Statement (E) accurately describes how a floating exchange rate is determined. It is the interplay of the relative supply and demand for the currencies involved in the exchange that sets the rate.

Additional Information on Floating Exchange Rates

Factors that can influence the supply and demand for a currency in a floating exchange rate system include:

• Interest Rates: Higher interest rates can attract foreign investment, increasing demand for the domestic currency.
• Inflation: Higher inflation relative to other countries can reduce demand for a currency as its purchasing power decreases.
• Economic Performance: Strong economic growth can attract investment, boosting demand for the currency.
• Political Stability: Political instability can lead to capital flight, increasing the supply of the domestic currency as investors sell it off.
• Trade Balance: A country exporting more than it imports (trade surplus) will see increased demand for its currency from buyers of its goods.

In a purely floating system, the government or central bank does not intervene to influence the rate. However, many countries operate under a "managed float" or "dirty float," where the central bank may occasionally intervene to smooth out excessive volatility without targeting a specific rate.
