The dollar's position as the world's leading reserve currency faces increased pressure as the financial crisis allows emerging economies greater influence on the world stage, analysts said.
A report last week in The Independent claiming that China, Russia and Gulf States are among nations prepared to ditch the dollar for oil trades has heightened the uncertainty surrounding the US currency's future.
The dollar slumped against rivals last week in the wake of the British daily's controversial report.
"The US dollar is being hurt by the continued talk of a shift away from a dollar-centric world," said Kit Juckes, an analyst at currency traders ECU Group.
