Here is a detailed and structured explanation of the Exchange Rate, including its meaning, determination, types, characteristics, and features:

What is Exchange Rate?
The exchange rate is the price of one country's currency in terms of another country's currency.
It tells us how much one unit of a currency can be exchanged for in another currency.
Example:
If 1 US Dollar = 83 Indian Rupees, then the exchange rate is ₹83/USD.

Exchange Rate Determination
Exchange rates are determined by the interaction of demand and supply of foreign exchange in the foreign exchange market.
1. Demand for Foreign Currency
Arises from imports, foreign travel, foreign education, investment abroad, etc.
2. Supply of Foreign Currency
Comes from exports, foreign investments in India, remittances, tourism income, etc.
Where the demand equals supply, the exchange rate is determined.

Theories/Methods of Exchange Rate Determination
1. Purchasing Power Parity (PPP) Theory
Based on the idea that the same product should cost the same in different countries when priced in a common currency.
If a product is cheaper in one country, currency will adjust until price levels equalize.
2. Interest Rate Parity
Suggests that exchange rates adjust so that there is no advantage in shifting funds from one country to another.
3. Balance of Payments Theory
States that exchange rate is determined by the overall balance of payments of a country.
A deficit leads to depreciation of currency, while a surplus leads to appreciation.
4. Supply and Demand Theory (Market Determination)
Exchange rate is simply the result of supply and demand in the forex market.
More demand for foreign currency → depreciation of domestic currency.

Types of Exchange Rate Systems
1. Fixed Exchange Rate
Government or central bank fixes the value of the domestic currency to another currency or gold.
Example: Bretton Woods system (USD was fixed to gold).
2. Flexible (Floating) Exchange Rate
Exchange rate is determined by market forces of demand and supply.
No government interference.
Most major currencies follow this (USD, Euro, INR).
3. Managed Floating Exchange Rate (Dirty Float)
Market forces determine exchange rate, but the central bank occasionally intervenes to stabilize it.
India follows this system.
