Forex plays a crucial role in global trade, enabling businesses and governments to conduct cross-border transactions. It affects exchange rates, impacting inflation, interest rates, and economic stability. Investors use forex for hedging currency risks and speculative trading, aiming to profit from price fluctuations. Central banks influence forex markets through monetary policies, interest rate decisions, and currency interventions. Additionally, forex provides opportunities for traders to leverage capital, although it comes with significant risk due to market volatility.
