speculation

Controversy about currency speculators and their effect on currency devaluations and national economies recurs regularly. Nevertheless, economists including Milton Friedman have argued that speculators ultimately are a stabilizing influence on the market and perform the important function of providing a market for hedgers and transferring risk from those people who don't wish to bear it, to those who do.[13] Other economists such as Joseph Stiglitz consider this argument to be based more on politics and a free market philosophy than on economics.[14]
Large hedge funds and other well capitalized "position traders" are the main professional speculators.
Currency speculation is considered a highly suspect activity in many countries. While investment in traditional financial instruments like bonds or stocks often is considered to contribute positively to economic growth by providing capital, currency speculation does not; according to this view, it is simply gambling that often interferes with economic policy. For example, in 1992, currency speculation forced the Central Bank of Sweden to raise interest rates for a few days to 500% per annum, and later to devalue the krona[15]. Former Malaysian Prime Minister Mahathir Mohamad is one well known proponent of this view. He blamed the devaluation of the Malaysian ringgit in 1997 on George Soros and other speculators.[16]
Gregory Millman reports on an opposing view, comparing speculators to "vigilantes" who simply help "enforce" international agreements and anticipate the effects of basic economic "laws" in order to profit.[16]
In this view, countries may develop unsustainable financial bubbles or otherwise mishandle their national economies, and forex speculators allegedly made the inevitable collapse happen sooner. A relatively quick collapse might even be preferable to continued economic mishandling. Mahathir Mohamad and other critics of speculation are viewed as trying to deflect the blame from themselves for having caused the unsustainable economic conditions. Given that Malaysia recovered quickly after imposing currency controls directly against IMF advice, this view is open to doubt

What is forex market

The Foreign Exchange market, also referred to as the "Forex" or "FX" market is the largest financial market in the world, with a daily average turnover of US$1.9 trillion -- 30 times larger than the combined volume of all U.S. equity markets. "Foreign Exchange" is the simultaneous buying of one currency and selling of another. Currencies are traded in pairs, for example Euro/US Dollar (EUR/USD) or US Dollar/Japanese Yen (USD/JPY). There are two reasons to buy and sell currencies. About 5% of daily turnover is from companies and governments that buy or sell products and services in a foreign country or must convert profits made in foreign currencies into their domestic currency. The other 95% is trading for profit, or speculation. For speculators, the best trading opportunities are with the most commonly traded (and therefore most liquid) currencies, called "the Majors." Today, more than 85% of all daily transactions involve trading of the Majors, which include the US Dollar, Japanese Yen, Euro, British Pound, Swiss Franc, Canadian Dollar and Australian Dollar.

A true 24-hour market, Forex trading begins each day in Sydney, and moves around the globe as the business day begins in each financial centre, first to Tokyo, London, and New York. Unlike any other financial market, investors can respond to currency fluctuations caused by economic, social and political events at the time they occur - day or night. The FX market is considered an Over The Counter (OTC) or 'interbank' market, due to the fact that transactions are conducted between two counterparts over the telephone or via an electronic network. Trading is not centralized on an exchange, as with the stock and futures markets
