Foreign exchange exposure is the risk associated with activities involving currencies other than a firm's home currency. It is the risk that foreign currencies may fluctuate in a way that financially harms the firm. There are three main types of foreign exchange exposure: transaction, economic, and translation. Firms can assess and manage their exposures through hedging strategies like financial contracts and operational techniques. Whether to hedge depends on factors like a firm's currency forecasts and focus on its core business versus currency speculation.
