The rupee weakened to its lowest level this week on Wednesday, tracking losses in the euro after a media report quoted German Chancellor Angela Merkel as expressing doubts on the success of the European project.
The euro fell to a session low after the report.
Traders said dollar demand from oil firms and defence companies also weighed on the rupee.
"Merkel's comments added to the euro's fall. There was dollar demand from defence firms and to some extent from oil as well," said Pramod Patil, a forex dealer at United Overseas Bank. He predicted the rupee's range between 55.20 and 55.75 for the week.
"Markets are disappointed as Bernanke didn't hint at any clear stimulus or easing as was being talked about."
