Published by Jamie JemmesonThe pace of growth in global forex trading slowed in the three years through to April as volatility and restricted credit reduced appetites for risk, according to the latest Bank for International Settlements currency market report.According to the group, forex trading volumes increased by 20 per cent to around $4 trillion a day on average, a substantial slowdown when compared to the 75 per cent growth seen over the preceding three years.Speaking to Bloomberg, Kevin Rodgers, London-based global head of foreign-exchange derivatives at Deutsche Bank AG, the world's largest currency trader, said there has been "complete chaos" in forex markets since the crisis began."Though [volatility] has come off, it remains historically high. The market is a very much jumpier, less-liquid place than it was pre-crisis," he explained.There have also been sharp movements from risky currencies to haven assets; in 2009, Brazil's real was the top-performing currency, while currently the Swiss franc and the yen are trading at the their highest levels in more than a decade.For more information on foreign exchange treasury services and risk management, visit our Corporate FX site.
