The following facts and figures relate to the foreign exchange market. Much of the information is drawn from the preliminary results of the 2007 Triennial Central Bank Survey of Foreign Exchange and Derivatives Market Activity conducted by the Bank for International Settlements (BIS) in April 2007 and released on September 25, 2007. 54 central banks and monetary authorities participated in the survey, collecting information from approximately 1280 market participants.
"The 2007 survey shows an unprecedented rise in activity in traditional foreign exchange markets compared to 2004. Average daily turnover rose to $3.2 trillion in April 2007, an increase of 71% at current exchange rates and 65% at constant exchange rates. Against the background of low levels of financial market volatility and risk aversion, market participants point to a significant expansion in the activity of investor groups including hedge funds, which was partly facilitated by substantial growth in the use of prime brokerage, and retail investors. A marked increase in the levels of technical trading – most notably algorithmic trading – is also likely to have boosted turnover in the spot market." - BIS
