Foreign exchange or ‘FX’ is a term used to describe the exchange or trading of one currency to another. The foreign exchange market has no central marketplace: spot and forward market transactions take place in an ‘Over-the-Counter’ market made up of dealers and large commercial and investment banks. Turnover in global foreign exchange (FX) markets reached $6.6 trillion per day in April 2019, according to data from the Bank for International Settlements (BIS). It is by far the largest financial market in the world. OTC markets are larger and more diversified than ever, owing in part to the rise of electronic and automated trading While trading continues to be dominated by the major currencies, in particular the US dollar and the euro, in FX markets the trading of emerging market currencies is growing faster than that of major currencies. The rise in electronic and automated trading is one of the key features of today’s foreign exchange markets.
