Step 1: Understanding the Concept:
In a flexible or managed floating system, the value of a currency is determined by market forces of demand and supply.
Step 2: Detailed Explanation:
- Appreciation: An increase in the value of the domestic currency relative to foreign currencies due to market forces.
- Depreciation: A decrease in the value of the domestic currency due to market forces.
- Devaluation: A deliberate reduction in the value of the domestic currency by the government in a fixed exchange rate system.
- Revaluation: A deliberate increase in the value of the domestic currency by the government in a fixed exchange rate system.
Step 3: Final Answer:
Since the question specifies a "rise" in currency value (increased purchasing power) in a "managed floating" system (market-driven), the correct term is Appreciation.
