The yen was down against the dollar and the euro in trading this morning (September 3rd) after a rise in Chinese equities provoked a move away from the low-risk, low-yield currency.During trading yesterday, the yen hit a seven-week high against the euro, with the Japanese currency establishing itself as the safe-haven of choice for forex traders.The upward movements yesterday came despite weaker than expected data from US payroll processor ADP showed that employment in the private sector dropped by 298,000 in August.The dollar has traditionally moved upwards on weaker domestic economic data, but in yesterday's trading the yen established a lead over the greenback as traders deemed it the most attractive of the two low-yield currencies.Speaking to Reuters, Tomohiro Nishida, treasury department manager at Chuo Mitsui Trust and Banking Company, said that the falls witnessed today on the back of strengthened Chinese equities will be only temporary.
