However, a firming trend in other Asian currencies against the dollar and a higher opening in the stock market capped the losses.
Forex traders said dollar demand from importers and oil companies mainly weighed on the rupee sentiment, but weakness of the Greenback against other Asian currencies and a higher opening in the stock market restricted the losses.
The rupee had ended 15 paise higher at Rs 45.09/10 against the dollar in the previous session amid sluggish demand for the US currency.
Meanwhile, the BSE benchmark Sensex was up by 76.37 points at 20,101.79 in opening trade today.
