Currency Devaluation vs Currency Depreciation
Both currency devaluation and currency depreciation involve a fall in the value of the domestic currency relative to a foreign currency. However, they differ mainly in how the fall in currency value occurs and the exchange rate system under which it takes place.
Currency Devaluation
Currency devaluation refers to the official reduction in the value of a country’s currency by the government or central bank under a fixed or pegged exchange rate system.
It is a deliberate policy decision rather than a change caused by market forces.
Example:
Suppose the officially fixed exchange rate is:
$1 = ₹50
The government or central bank officially changes it to:
$1 = ₹60
The rupee has been devalued because more rupees are now required to purchase one US dollar.
$1 = ₹50 → $1 = ₹60 → Rupee Devalued
Currency Depreciation
Currency depreciation refers to a fall in the value of a country’s currency relative to another currency due to market forces under a flexible or managed floating exchange rate system.
It occurs because of changes in the demand and supply of currencies in the foreign exchange market.
Example:
Suppose the market exchange rate changes from:
$1 = ₹85 → $1 = ₹90
The rupee has depreciated because more rupees are now required to purchase one US dollar.
Key Differences between Devaluation and Depreciation
| Basis | Currency Devaluation | Currency Depreciation |
|---|---|---|
| Meaning | Official reduction in the value of a currency | Market driven fall in the value of a currency |
| Exchange Rate System | Fixed or pegged exchange rate system | Flexible or managed floating exchange rate system |
| Cause | Deliberate policy decision | Changes in demand and supply of currencies |
| Determined By | Government or central bank | Foreign exchange market |
| Nature | Officially administered | Market driven |
| Example | Official rate: $1 = ₹50 → ₹60 | Market rate: $1 = ₹85 → ₹90 |
| Opposite | Revaluation | Appreciation |
Economic Impact
Although their mechanisms are different, devaluation and depreciation have broadly similar economic effects:
- Imports Become Costlier: More domestic currency is required to purchase foreign goods and services.
- Exports Become More Competitive: Domestic goods become relatively cheaper for foreign buyers.
- Trade Balance May Improve: Costlier imports and more competitive exports can encourage exports and discourage imports.
- Inflationary Pressure May Increase: Imported crude oil, raw materials, machinery and intermediate goods become costlier, contributing to imported inflation.
- Foreign Currency Debt Becomes Costlier: More domestic currency is required to service and repay foreign currency denominated debt.
- Foreign Travel and Education Become Costlier: Residents require more domestic currency to obtain the same amount of foreign currency.
- Remittances Become More Valuable: The same amount of foreign currency received from abroad converts into more domestic currency.
