The rupee depreciated by another 17 paise to 66.84 against the US dollar in early trade today on increased demand for the greenback from importers amid appreciation in the American currency overseas.
Dealers attributed the fall to a lower opening of the domestic equity market.
Yesterday, the rupee had lost 9 paise to close at 66.67 against the US dollar.
Meanwhile, the benchmark BSE Sensex tanked 337.49 points, or 1.31%, to 25,435.04 in early trade today.
