The rupee weakened further by 9 paise to 64.27 against the US dollar in early trade at the Interbank Forex market today on increased demand for the American currency from importers and banks.

Besides, the dollar's strength against some other currencies overseas also weighed on the domestic currency.

Dealers attributed the rupee’s fall to increased demand for the US currency and a weak domestic equity market.

Yesterday, the rupee had shed 3 paise to close at 64.18 against the US dollar on fresh demand for the dollar.

Meanwhile, the benchmark BSE Sensex fell 133.04 points or 0.44 per cent to 29,993.17 in early trade.
