Dealers attributed the rupee's fall to fresh demand for the US currency, but dollar's weakness against some currencies overseas restricted the losses.
Besides, a lower opening of the domestic equity market weighed on the rupee, they said.
The rupee had appreciated by 15 paise to close at four-month high of 66.37 against the US currency in yesterday's trade.
Meanwhile, the benchmark BSE Sensex fell by 71.80 points or 0.24 per cent to 28,854.56 in early trade.
