Meaning
Exchange Rate is the rate at which one currency is exchanged for another in the foreign exchange market. It expresses the price of one unit of foreign currency in terms of the domestic currency.
National Testing Agency: Class 12
Exchange Rate Systems
There are two main systems of exchange rate determination:
- Flexible (Floating) Exchange Rate System
- Fixed Exchange Rate System
| Feature | Flexible Exchange Rate | Fixed Exchange Rate |
|---|---|---|
| Determined by | Demand and supply in the foreign exchange market | Government / Central Bank (RBI) |
| Government Intervention | No regular intervention | RBI buys/sells foreign exchange to maintain the fixed rate |
| Fall in domestic currency value | Depreciation | Devaluation |
| Rise in domestic currency value | Appreciation | Revaluation |
| Historical Examples | — | Gold Standard, Bretton Woods System |
National Testing Agency: Class 12
Flexible (Floating) Exchange Rate
The exchange rate is determined by the demand and supply of foreign exchange in the market.

Equilibrium under Flexible Exchange Rates
Equilibrium is reached where Demand (DD) = Supply (SS).
If demand for foreign currency increases,
- Exchange rate rises.
- Domestic currency depreciates.
- Foreign currency appreciates.

Effect of an Increase in Demand for Imports in the Foreign Exchange Market
Example:
₹50/\[$\]→₹70/\[$\]
If demand for foreign currency decreases,
- Exchange rate falls.
- Domestic currency appreciates.
Factors Affecting Flexible Exchange Rate
1. Speculation
- Expectation of appreciation of a foreign currency increases its demand, causing the exchange rate to rise.
2. Interest Rate Differential
- Higher domestic interest rates attract foreign investment, increasing demand for domestic currency and causing it to appreciate.
3. Income Changes
- Higher national income increases imports, raising demand for foreign exchange and causing domestic currency to depreciate.
4. Purchasing Power Parity (PPP)
- In the long run, exchange rates reflect differences in price levels between countries.
Formula: Interest Rate Differential
\[\text{Interest Rate Differential}=i_A-i_B\]
Formula: Exchange Rate
\[\text{Exchange Rate (PPP)}=\frac{\text{Domestic Price}}{\text{Foreign Price}}\]
National Testing Agency: Class 12
Fixed Exchange Rate
The exchange rate is fixed by the Government or RBI and maintained through intervention in the foreign exchange market.

Foreign Exchange Market with Fixed Exchange Rates
- Devaluation: Official increase in exchange rate (domestic currency becomes cheaper).
- Revaluation: Official decrease in exchange rate (domestic currency becomes costlier).
If the fixed rate is above equilibrium, RBI buys foreign exchange.
If the fixed rate is below equilibrium, RBI sells foreign exchange.
National Testing Agency: Class 12
Historical Fixed Exchange Rate Systems
Gold Standard System
Each country fixed the value of its currency in terms of gold.
Bretton Woods System
- Established in 1944.
- Countries fixed their currencies against the US Dollar.
- Supervised by the International Monetary Fund (IMF).
National Testing Agency: Class 12
Key Points: Determination of the Exchange Rate
- Exchange rate = Price of one unit of foreign currency in terms of domestic currency.
- Flexible exchange rate is determined by Demand = Supply.
- Increase in demand for foreign currency → Depreciation of domestic currency.
- Decrease in demand for foreign currency → Appreciation of domestic currency.
- Main determinants: Speculation, Interest Rate Differential, Income Changes, PPP.
- Fixed exchange rate is maintained by Government/RBI through buying or selling foreign exchange.
- Depreciation/Appreciation occur under a Flexible system.
- Devaluation/Revaluation occur under a Fixed system.
