Historical Context
The revaluation of a currency refers to the intentional increase in the value of a nation’s currency relative to other currencies or a standard such as gold. Historically, currency revaluations have been less common than devaluations and typically occur when a country experiences a prolonged balance of payments surplus, indicating an excess of exports over imports.
Types and Categories
- Official Revaluation: Government-driven revaluation often to address economic imbalances.
- Market-Driven Revaluation: Occurs when market forces, such as demand for a currency, naturally increase its value.
Key Events
- 1985 Plaza Accord: A notable instance where several major economies agreed to devalue the US dollar relative to the Japanese yen and the German Deutsche Mark, affecting the global exchange rate system.
- Chinese Yuan (2010): China’s currency revaluation to address trade imbalances with the United States.
Detailed Explanations
Revaluation impacts both international trade and the domestic economy. When a currency is revalued:
- Imports Become Cheaper: As the value of the currency increases, it buys more foreign goods.
- Exports Become More Expensive: Domestically produced goods become costlier for foreign buyers, potentially reducing export volumes.
Mathematical Formulas and Models
Exchange rates are determined by various economic models, including:
- Purchasing Power Parity (PPP):
$$ \text{Exchange Rate (ER)} = \frac{P_1}{P_2} $$Where \( P_1 \) and \( P_2 \) are price levels in different countries.
- Interest Rate Parity (IRP):
$$ (1 + i_{domestic}) = \frac{F}{S} (1 + i_{foreign}) $$Where \( i \) represents interest rates, and \( F \) and \( S \) are forward and spot exchange rates.

Importance and Applicability
Currency revaluation plays a crucial role in:
- International Trade: Affecting trade balances and economic relations between countries.
- Domestic Economy: Influencing inflation rates and purchasing power of consumers.
Examples
- Swiss Franc (CHF) Revaluation: The Swiss National Bank’s decision to unpeg CHF from the Euro in 2015, leading to a significant revaluation of the Franc.
