Mumbai: The rupee weakened 6 paise to quote at 66.45 against the dollar in early trade today on increased month-end demand for the American currency from importers and banks.
The dollar was firm against major global currencies, which dampened rupee sentiment, but a higher opening of the domestic equity market capped the losses, dealers said.
The rupee had gained one paisa to end at 66.39 yesterday on fag-end selling of the US currency by banks.
Meanwhile, the benchmark BSE Sensex rose 42.21 points, or 0.16 per cent, to 26,002.24 in early trade.
