Forex Financial obligation

The only initial financial obligation of the foreign currency option buyer is to pay the premium to the seller up front when the foreign currency option is initially purchased. Once the premium is paid, the foreign currency option holder has no other financial obligation (no margin is required) until the foreign currency option is either offset or expires.

On the expiration date, the call buyer can exercise his or her right to buy the underlying foreign currency spot position at the foreign currency option's strike price, and a put holder can exercise his or her right to sell the underlying foreign currency spot position at the foreign currency option's strike price. Most foreign currency options are not exercised by the buyer, but instead are offset in the market before expiration.

Initially, the foreign currency option seller collects the premium paid by the foreign currency option buyer (the buyer's funds will immediately be transferred into the seller's foreign currency trading account). The foreign currency option seller must have the funds in his or her account to cover the initial margin requirement. If the markets move in a favorable direction for the seller, the seller will not have to post any more funds for his foreign currency options other than the initial margin requirement. However, if the markets move in an unfavorable direction for the foreign currency options seller, the seller may have to post additional funds to his or her foreign currency trading account to keep the balance in the foreign currency trading account above the maintenance margin requirement.
