Currency options are financial derivatives that provide the buyers the right, but not the obligation, to exchange a specific amount of one currency for another at a predetermined exchange rate on or before a specified expiration date. Unlike futures contracts, which obligate the parties to exchange at a predetermined future date, currency options offer more flexibility.
