The US dollar rose against its major counterparts during trading on Thursday (October 1st) as investors looked for a safe haven.Following gloomy manufacturing data emerging in the US, Britain and the eurozone, there was a flight to low-yield currencies such as the dollar and the yen.Lee Hardman, of the Bank of Tokyo-Mitsubishi, told the Financial Times that a transatlantic rift is developing over currency policy, with Jean-Claude Trichet, president of the European Central Bank, this week urging his Federal Reserve counterpart Ben Bernanke to tow a strong line on the dollar."The euro has come under downward pressure coinciding with both stabilisation in the dollar’s descent and growing concern from European officials over the euro’s strength," he explained.Reflecting on the re-emergence on the cautious attitude to risk this week, Daily FX yesterday claimed that the flock to the low-yielders appears "unusual" given the raft of bullish economic data that has emerged in recent weeks.
