Fixed Exchange Rate vs Flexible Exchange Rate: Complete Class 12 Economics Notes

Exchange rate refers to the price of one country's currency in terms of another country's currency. For example, if 1 US Dollar = ₹85, then the exchange rate of the Indian Rupee against the US Dollar is ₹85 per dollar. Exchange rates play a crucial role in international trade, foreign investment, tourism, and economic stability.

What is an Exchange Rate?

An exchange rate is the rate at which one currency can be exchanged for another currency. Whenever a country imports goods, exports products, receives foreign investment, or sends money abroad, exchange rates become important.

Example:

• 1 USD = ₹85
• 1 Euro = ₹95
• 1 Pound Sterling = ₹112

These rates constantly affect the cost of imports and exports.

Types of Exchange Rate Systems

There are two major exchange rate systems:

1. Fixed Exchange Rate System
2. Flexible Exchange Rate System

Fixed Exchange Rate System

Under a fixed exchange rate system, the government or central bank fixes the value of its currency against another currency or a basket of currencies.

The exchange rate remains stable because the central bank actively intervenes in the foreign exchange market.

Example:

Suppose the government decides:

1 USD = ₹80

If market forces try to move the exchange rate above or below ₹80, the central bank will buy or sell foreign currency to maintain the fixed rate.

Features of Fixed Exchange Rate

• Government determines exchange rate.
• Central bank intervention is necessary.
• Exchange rate fluctuations are limited.
• Provides stability in international trade.
• Requires large foreign exchange reserves.

Advantages of Fixed Exchange Rate

• Promotes international trade.
• Reduces uncertainty.
• Encourages foreign investment.
• Creates confidence among investors.
• Controls excessive currency volatility.

Disadvantages of Fixed Exchange Rate

• Requires huge foreign exchange reserves.
• Government loses monetary policy flexibility.
• Artificial exchange rates may distort markets.
• Difficult to maintain during economic crises.

Flexible Exchange Rate System

Under a flexible exchange rate system, exchange rates are determined by the forces of demand and supply in the foreign exchange market.

The government does not fix the value of the currency.

Instead, market participants determine the exchange rate.

How Flexible Exchange Rate Works

If demand for US dollars increases in India, the value of the dollar rises and the rupee depreciates.

If demand for Indian rupees increases globally, the rupee appreciates.

Thus exchange rates continuously adjust according to market conditions.

Features of Flexible Exchange Rate

• Market-determined exchange rates.
• Limited government intervention.
• Demand and supply determine currency value.
• Automatic adjustment mechanism.
• Exchange rates fluctuate frequently.

Advantages of Flexible Exchange Rate

• Automatic correction of balance of payments imbalance.
• No need for large foreign exchange reserves.
• Independent monetary policy.
• Efficient allocation of resources.
• Reflects true market conditions.

Disadvantages of Flexible Exchange Rate

• Creates uncertainty for exporters and importers.
• Can lead to excessive volatility.
• May encourage speculation.
• Can increase inflation through imported goods.

Difference Between Fixed and Flexible Exchange Rate

Basis	Fixed Exchange Rate	Flexible Exchange Rate
Determination	Government	Demand and Supply
Intervention	High	Low
Stability	High	Low
Foreign Exchange Reserves	Required	Less Required
Monetary Policy Freedom	Limited	Greater

Managed Floating Exchange Rate

Many countries including India follow a managed floating exchange rate system.

In this system, exchange rates are largely determined by market forces, but the central bank occasionally intervenes to prevent excessive fluctuations.

This system combines the benefits of both fixed and flexible exchange rates.

Exchange Rate and Demand for Foreign Currency

The demand for foreign currency arises due to:

• Imports
• Foreign travel
• Foreign education
• Foreign investment
• Loan repayments

Higher demand for foreign currency tends to depreciate domestic currency.

Exchange Rate and Supply of Foreign Currency

Supply of foreign currency arises due to:

• Exports
• Foreign investment inflows
• Remittances
• Tourism receipts
• Foreign aid

Higher supply of foreign currency tends to appreciate domestic currency.

Real-Life Example from India

Suppose crude oil prices increase globally.

India imports a large quantity of crude oil. Therefore, Indian importers require more US dollars. Demand for dollars rises and the rupee may depreciate from ₹83 per dollar to ₹86 per dollar.

This illustrates how market forces affect exchange rates under a flexible exchange rate system.

Importance of Exchange Rate

• Affects exports and imports.
• Influences inflation.
• Determines international competitiveness.
• Impacts foreign investment.
• Affects balance of payments.

Conclusion

Exchange rate systems determine how the value of a currency is established in the foreign exchange market. A fixed exchange rate provides stability but requires government intervention, while a flexible exchange rate allows market forces to determine currency values. India follows a managed floating system where the Reserve Bank of India intervenes occasionally to maintain orderly market conditions.
