Step 1: Understanding the Concept:
In an international economy with a flexible (floating) exchange rate system, the price of one currency in terms of another is determined by the market forces of demand and supply. Foreign exchange is demanded for imports, foreign travel, and investments abroad, while it is supplied through exports and foreign investments coming into the country. When the relative demand for a foreign currency (like the US Dollar) increases or the supply of the domestic currency (like the Rupee) becomes excessive, the market price of the foreign currency rises.
Step 2: Detailed Explanation:
1. Currency Depreciation: This occurs when the domestic currency loses value relative to a foreign currency due to market forces. For example, if the exchange rate changes from $\$1 = ₹80$ to $\$1 = ₹85$, it now takes more Rupees to buy one Dollar. This means the Rupee has weakened or "depreciated." This usually happens when a country has a high trade deficit or low demand for its exports.
2. Currency Appreciation (Option A): This is the opposite. If the rate moves from $\$1 = ₹80$ to $\$1 = ₹75$, the Rupee has gained value. It now takes fewer Rupees to buy a Dollar, indicating a stronger domestic currency.
3. Inflation vs. Deflation (Options B and D): These terms refer to the internal purchasing power of money—the general rise or fall in the prices of goods {inside} the country. While high domestic inflation can lead to currency depreciation over time (as the currency's value erodes), they are separate concepts. One refers to the price of goods; the other refers to the price of another currency.
4. Note on Devaluation: It is important not to confuse depreciation with devaluation. Devaluation is a deliberate reduction in the value of a currency by the government in a fixed exchange rate system, whereas depreciation happens automatically in a market-based system.
Step 3: Final Answer:
Since the scenario describes a fall in the Rupee's value against the Dollar in a market context, the correct term is Depreciation.
