Forex or the foreign exchange of currencies, as facilitated by forex brokers and banks, has become an integral part of business operations in this new age of globalization. Although the U.S. dollar is still the preferred tender in the world market, U.S. companies, or dollar-earning enterprises, may have to trade their dollars for other currencies to facilitate faster business transactions in foreign countries.

Most big international conglomerates that operate corporations and plants all over the world invest in keeping different currencies. Several companies also earn from the fluctuations in the money market by stocking up on currencies such as the euro, the yen, and the pound then selling them when their value strengthens against the U.S. dollar.

Because of the great impact of the supply of dollar reserves on any government, forex trading is heavily regulated. Individuals and companies may only buy or sell, or bring in or take out of the country certain legal amounts of currency. This poses a problem, especially for companies that need to put up a lot of cash in dollars to buy large assets. This is where forex brokers come in and assist them in raising the needed funds.

Dabbling in forex is a bit like dealing with equities. The market is volatile and often requires taking action based on forecasts that, when right, can lead to huge profits. However, when these forecasts are wrong, they can cause big losses. The risks are enough to deter many, but the same uncertainties and the surprises, as well as the strategic aspect of the activity also attracts many to invest in buying and selling foreign currencies. The only difference is that forex brokers do not charge commissions, unlike equities brokers. Forex brokers get their earnings from the spreads or the difference between the purchase price of a currency and the selling price after fluctuation.
