SINGAPORE (AFX-ASIA) - The dollar continued to weaken in subdued trading, with Japan closed for a public holiday, as the market continued to sell US dollars following president George W Bush's comments that the value of the US unit should be determined by the market, dealers said. Bush's comments had largely been interpreted as a move away from a strong US dollar policy, dealers said. FOMC chairman Alan Greenspan's comments about the US economy earlier, also reminded the market of the downside risk for the US economy going forward. A currency strategist with a European brokerage said a lot of the players which were long on usd/yen are continuing to sell US dollars, allowing the yen to appreciate towards the 122/usd level. "I see the floor for usd/yen at 122.30. The fundamental argument for the yen is weaker in absence of improvements in the Japanese economy," she said.
