Imagine you run a business that must pay a supplier in euros three months from now. You are worried the euro could get stronger, making your dollar cost bigger, but you would also love to benefit if the euro gets weaker. A forward contract locks you into one rate, no matter what. Currency options give you a better deal: protection if the move hurts you, and freedom to profit if it helps you. This chapter teaches you how these tools work, how their prices are set, and how professionals combine them into useful hedging and trading strategies.
