Besides increased dollar demand from importers and euro's weakness overseas ahead of a European leaders austerity meeting later in the week, a lower opening in the domestic equity market put pressure on the rupee, forex dealers said.
Meanwhile, the BSE benchmark Sensex fell by 74.52 points, or 0.39 per cent, to 18,600.66 in early trade today.
The rupee had lost 13 paise to end at 52.81 against the dollar in the previous session on Friday.
