Foreign exchange options
In finance, a foreign exchange option (commonly shortened to just FX option or currency option) is a derivative financial instrument where the owner has the right but not the obligation to exchange money denominated in one currency into another currency at a pre-agreed exchange rate on a specified date; see Foreign exchange derivative.
The FX options market is the deepest, largest and most liquid market for options of any kind in the world. Most of the FX option volume is traded OTC and is lightly regulated, but a fraction is traded on exchanges like the International Securities Exchange, Philadelphia Stock Exchange, or the Chicago Mercantile Exchange for options on futures contracts. The global market for exchange-traded currency options was notionally valued by the Bank for International Settlements at $158,300 billion in 2005.
For example a GBPUSD FX option might be specified by a contract giving the owner the right but not the obligation to sell £1,000,000 and buy $2,000,000 on December 31. In this case the pre-agreed exchange rate, or strike price, is 2.0000 USD per GBP (or 0.5000 GBP per USD) and the notionals are £1,000,000 and $2,000,000.
This type of contract is both a call on dollars and a put on sterling, and is often called a GBPUSD put by market participants, as it is a put on the exchange rate; it could equally be called a USDGBP call, but market convention is quote GBPUSD (USD per GBP).
If the rate is lower than 2.0000 come December 31 (say at 1.9000), meaning that the dollar is stronger and the pound is weaker, then the option will be exercised, allowing the owner to sell GBP at 2.0000 and immediately buy it back in the spot market at 1.9000, making a profit of (2.0000 GBPUSD – 1.9000 GBPUSD)*1,000,000 GBP = 100,000 USD in the process. If they immediately exchange their profit into GBP this amounts to 100,000/1.9000 = 52,631.58 GBP.
Currency futures history
Currency futures were first created at the Chicago Mercantile Exchange (CME) in 1972, less than one year after the system of fixed exchange rates was abandoned along with the gold standard. Some commodity traders at the CME did not have access to the inter-bank exchange markets in the early 1970s, when they believed that significant changes were about to take place in the currency market. They established the International Monetary Market (IMM) and launched trading in seven currency futures on May 16, 1972. Today, the IMM is a division of CME. In the fourth quarter of 2009, CME Group FX volume averaged 754,000 contracts per day, reflecting average daily notional value of approximately $100 billion. Currently most of these are traded electronically.
Other futures exchanges that trade currency futures are Euronext.liffe, Tokyo Financial Exchange and IntercontinentalExchange.
