The rupee depreciated 18 paise to 65.13 against the dollar at the Interbank Foreign Exchange in early trade on October 8 on buying of the US currency by importers.
The dollar was firm against major global currencies which dampened the rupee sentiment, forex dealers said.
The rupee also fell due to fresh demand for dollar from importers, but a higher opening in the domestic equity market capped the losses, they added.
Yesterday, the rupee recuperated by 46 paise to close at an eight-week high of 64.95 against the US dollar on fresh selling of the American currency by banks and exporters on persistent foreign capital inflows into domestic equities.
Meanwhile, the benchmark Sensex rose 81.01 points or 0.3 per cent to 27,116.86 in opening trade.
