Introduction
Currency revalorization is a financial process that alters the value of a currency relative to other currencies, assets, or its own historical value. Governments and central banks undertake revalorization to correct distortions, restore purchasing power, or stabilize the economy. This article explores the meaning, mechanisms, and real-world effects of revalorization.

What Is Revalorization of Currency?
Revalorization is the opposite of devaluation. It increases the official value of a currency in terms of a benchmark such as gold, another currency, or a basket of assets. A government revalues its currency when economic conditions support a stronger monetary unit.
Key Differences Between Devaluation, Revaluation, and Revalorization
| Term | Definition | Causes |
|---|---|---|
| Devaluation | A deliberate reduction in the currency’s value by the government. | High inflation, trade imbalances, weak economic growth. |
| Revaluation | A deliberate increase in the currency’s official value. | Strong economic growth, high foreign reserves, improved trade balance. |
| Revalorization | A process that restores the currency’s value to its original or intended level. | Policy corrections, economic stabilization, inflation control. |
Process of Currency Revalorization
Revalorization follows a structured approach where economic conditions, monetary policy, and market dynamics are assessed before implementing changes.
1. Identifying the Need for Revalorization
Economic indicators such as inflation, trade balance, and exchange rate trends determine whether a currency needs revalorization. When a currency loses purchasing power due to inflation, policymakers may restore its original value.
Example: Suppose a country experiences a 30% depreciation of its currency due to inflation. If the government intends to restore purchasing power, revalorization may adjust the currency upward by 30% to neutralize inflationary effects.
2. Government and Central Bank Intervention
The central bank plays a key role in currency revalorization. It adjusts monetary policy, interest rates, and reserves to strengthen the currency.
Mathematically, if a government decides to increase the currency’s value by RR percent, the new exchange rate ER′ER’ can be calculated as:
ER' = ER \times \left( 1 + \frac{R}{100} \right)where:
- ERER is the existing exchange rate,
- RR is the percentage revalorization.
Example: If ER=1.5ER = 1.5 USD per unit of currency and the government revalorizes by 10%, the new exchange rate is:
3. Market Adjustments and Economic Effects
Revalorization affects inflation, trade balance, and foreign investment. If done correctly, it stabilizes purchasing power without creating shocks.
Impact on Inflation
Revalorization can lower inflation by reducing the cost of imports. Using the Inflation-Pass-Through Model, the inflationary effect post-revalorization is:
\pi' = \pi - \alpha \times Rwhere:
- π′\pi’ is the new inflation rate,
- π\pi is the previous inflation rate,
- α\alpha is the pass-through coefficient,
- RR is the revalorization percentage.
If the current inflation rate is 7%, α=0.5\alpha = 0.5, and revalorization is 10%, then:
\pi' = 7 - 0.5 \times 10 = 2%Real-World Examples of Currency Revalorization
Switzerland and the Swiss Franc (2015)
In 2015, the Swiss National Bank removed the EUR/CHF floor rate of 1.20, leading to an appreciation of the Swiss franc by nearly 20% in one day. This revalorization impacted exports but lowered inflation.
Germany’s Post-WWII Currency Reform
In 1948, Germany introduced the Deutsche Mark, replacing the Reichsmark. This move restored the currency’s value and controlled hyperinflation.
Implications of Revalorization
1. Impact on Exports and Imports
| Scenario | Exports | Imports |
|---|---|---|
| Currency appreciates | Becomes expensive | Becomes cheaper |
| Currency depreciates | Becomes cheaper | Becomes expensive |
A stronger currency makes imported goods cheaper but may hurt exporters.
2. Effects on Investment and Debt
Revalorization affects capital flows and foreign debt. If a country’s currency strengthens, foreign-denominated debt becomes cheaper.
Debt burden post-revalorization:
D' = D \times \left( \frac{ER}{ER'} \right)where:
- D′D’ is the new debt burden,
- DD is the original debt,
- ERER and ER′ER’ are the old and new exchange rates.
If a country owes $100\$100 billion at 1.5 USD/exchange rate, and revalorization strengthens it to 1.65, then:
D' = 100 \times \left( \frac{1.5}{1.65} \right) = 90.9 \text{ billion}This reduces the debt burden by nearly 9%.
Conclusion
Currency revalorization is a critical policy tool used to correct economic distortions and restore monetary stability. It influences inflation, trade, and investment. When executed properly, revalorization strengthens economic fundamentals without disrupting financial stability. However, improper implementation can cause economic imbalances. Therefore, policymakers must assess market conditions, fiscal policy, and external trade factors before initiating revalorization.
