The dollar skidded to an all-time low against the Swiss franc on Wednesday and fell against the euro after poor manufacturing and employment data stoked expectations that US interest rates will remain low for longer than markets have expected.
Optimism that Greece will avoid restructuring its massive debt load also supported the euro, driving it to a four-week high against dollar.
The dollar fell against the franc to record low of 0.83830 and was last down 1.5 percent at 0.8408 francs.
The euro also hit a record trough versus the Swiss currency at 1.2085. It last traded at 1.2114, down 1.4 percent.
Against the yen, which also benefited from its safe-haven appeal, the dollar was down 0.8 percent at 80.86 yen. In late morning New York trade, the euro was up 0.1 percent at $1.4404. A UK trader said there was protective selling ahead of $1.44550 barriers, with more sell orders toward $1.4480 ahead of huge barrier option at around $1.4500.
