FX derivatives are financial instruments used to speculate on currency exchange rates, engage in arbitrage, or hedge foreign exchange risk. They evolved as a means to manage risks from volatility in world markets like inflation and oil shocks that create uncertainty around profits, cash flows, and costs due to fluctuating exchange rates. In India, FX derivatives developed as the economy gradually liberalized, exchange rates deregulated, and businesses increasingly approached foreign markets, where derivatives help reduce interest costs and protect revenues from currency volatility.
