The dollar dropped to a record low against the euro today as troubles in the US mortgage and credit markets continued to dampen the currency's appeal.
The dollar also hovered around a two-and-a-half-year low against a basket of six major currencies, as investors worried that credit market problems could hurt the economy and lead the Federal Reserve to cut interest rates by year-end.
"There is still some jitters about the subprime issue and that's still weighing on the dollar," said Nick Bennenbroek, head of FX strategy at Wells Fargo in New York.
Subprime loans are extended to borrowers with poor credit histories.
"There's some concern about the economy, that troubles in those sectors will spread to other areas of financial markets and cause a broader slowdown. Also, we have seen expectations of a rate cut start to come back into calculations and this is a reflection of the subprime jitters," he added.
Early in New York, the euro was up 0.2 per cent on the day against the dollar at $1.3770, having set a record high of $1.3799. The single currency also hit a lifetime peak at 168.65 yen, according to electronic trading platform EBS, before trading back down to 168.48, up 0.2 percent on the day.
US data showing the trade deficit widened as expected in May had marginal impact on the dollar.
"The trade numbers are roughly in line with expectations, but we are going to keep seeing the dollar declining from here," said Mark Meadows, a market analyst at Tempus Consulting in Washington. "There's very little in terms of economic data in the near term that could lift it."
