Published by Jamie JemmesonThe dollar was on the defensive in global forex trading this morning (September 2nd), retaining much of the losses sustained during yesterday's migration into riskier assets.Stronger manufacturing data from both the US and China helped to ease fears that the world's largest and fastest growing economies may be slowing.In turn, forex brokers began unwinding their positions in haven assets and moving into higher-yield currencies, pushing both the dollar and the yen lower.Speaking to Reuters about this morning's trade, Shuichi Kanehira, head of FX spot trading at Mizuho Corporate Bank, said traders need further assurance before taking larger risks."Investors are not aggressively taking risks yet, feeling they need to see the US employment figures before deciding how much risk they can really take," he said.There are a number of potentially high-impact events scheduled on today's trading calendar, including US unemployment claims and pending home sales figures, as well as testimony from Fed chairman Ben Bernanke.For more information on foreign exchange treasury services and risk management, visit our Corporate FX site.
