Currency Option

A currency option is a type of foreign exchange derivative. After paying a premium, the buyer obtains the right, but not the obligation, to buy or sell a specified amount of a certain currency at an agreed exchange rate (strike price) on or before a specified date. Use cases: foreign trade companies use them to hedge against exchange rate fluctuation risk while retaining the opportunity to benefit if the exchange rate moves favorably; commonly used in import/export receipts and payments, bidding, and financing. Notes: a premium (cost) must be paid; American options can be exercised at any time before expiry, while European options can only be exercised on the expiry date; over-the-counter options require attention to counterparty credit risk. Difference from a forward foreign exchange contract: a forward contract imposes obligations on both parties and must be settled at the agreed exchange rate at maturity, with no option premium; an option is a right for the buyer, who may choose not to exercise it, but must pay a premium. Difference from currency futures: futures are standardized exchange-traded contracts, while options can be customized over the counter.
