People Speculate in Foreign Exchange to earn Profits
Example 1
Suppose Exchange Rate of Dollar is currently Rs 70 per Dollar
Person feel that it will rise in future to Rs 80 per Dollar
So they will Purchase Dollar today @ Rs 70 and sell it later at Rs 80
So there is Increase in Demand of Foreign Currency
Example 2
Suppose Exchange Rate of Dollar is currently Rs 70 per Dollar
Person feel that it will fall in future to Rs 60 per Dollar
So they will Sell Dollar today @ Rs 70 and purchase it later at Rs 60
Selling now decreases demand of foreign exchange
So there is decrease in demand of foreign currency
