In the contemporary international monetary system, floating exchange rates are the norm. However, different governments pursue a variety of alternative policy mixes or attempt to minimize exchange rate fluctuations through different strategies. For example, the United States displayed a preference for ad hoc international coordination, such as the Plaza Agreement in 1985 and the Louvre Accord in 1987, to intervene and manage the price of the dollar. Europe responded by forging ahead with a regional monetary union based on the desire to eliminate exchange rate risk, whereas many developing governments with smaller economies chose the route of “dollarization”—that is, either fixing to or choosing to have the dollar as their currency.
Most developed countries permit the trading of derivative products (such as futures and options on futures) on their exchanges. All these developed countries already have fully convertible capital accounts. Some governments of emerging markets do not allow foreign exchange derivative products on their exchanges because they have capital controls. The use of derivatives is growing in many emerging economies. Countries such as South Korea, South Africa, and India have established currency futures exchanges, despite having some capital controls.
There are actually three ways that institutions, corporations and individuals trade forex: the spot market, the forwards market and the futures market. The forex trading in the spot market always has been the largest market because it is the "underlying" real asset that the forwards and futures markets are based on. In the past, the futures market was the most popular venue for traders because it was available to individual investors for a longer period of time. However, with the advent of electronic trading and numerous forex brokers, the spot market has witnessed a huge surge in activity and now surpasses the futures market as the preferred trading market for individual investors and speculators. When people refer to the forex market, they usually are referring to the spot market. The forwards and futures markets tend to be more popular with companies that need to hedge their foreign exchange risks out to a specific date in the future.
