Global forex trading (forex, of course, meaning the foreign exchange market) has become more and more popular in the last few decades, mostly due to the advent of the global economy. Never before has our economy been so intertwined with every other country. It is perfectly common now for people to convert large amounts of money into various foreign currencies, then back again. The forex market is the largest market in the world, and includes everything from banks to governments to independent speculators. The daily volume of the global forex trading market exceeded four trillion dollars on average last year, making it a very attractive market to get involved in.

Several things separate global forex trading from other markets. Its trading volumes, the large number and variety of traders, the global dispersion, the variety of factors affecting exchange rates, low profit margins (but profits are often very high because of large volume trading), all contribute to make the global forex trading market the closest thing to the perfect competition. Foreign exchange has more than doubled since 2001.

Another way that global forex trading is separated from other markets, for example the stock market, is that it is divided into different levels of access. In the stock market, all competitors and investors have access to the same prices. In the global forex market, however, the inter-bank market is at the top. As the access level drops, the spread (that is the difference between the bid and ask price) widens, though it is still possible for a low-access individual to make large amounts of money.

While there is not a central market for forex traders, there is next to no cross-border regulation. Global forex trading is often referred to as OTC (over-the-counter), which makes for a large number of intertwined marketplaces. Therefore there is not so much a single exchange as a number of separate rates or prices, depending on which bank is doing the trading, and where it is. Differences in exchange rates are usually caused by changes in GDP (gross domestic product), inflation, interest rates, budget and trade deficits or surpluses, and other large-scale economic transactions and events.

Global forex trading is something not many people consider for investment (who would think that so much money lies in money), but worldwide forex trading continues to flourish for a reason. Individuals all over the globe are investing in the forex market and making thousands of dollars every day.
