Forex dealers attributed the weakness of the dollar against other currencies to investors viewing the recent spurt of the greenback as unsubstantiated which supported the rupee.
A higher opening in the domestic equity market also influenced the rupee uptrend, they added.
Yesterday, the rupee had settled almost flat with negative bias at 68.21 against the US currency in restricted trade.
Meanwhile, the benchmark BSE Sensex rose 119.88 points, or 0.45 per cent, at 26,468.98 in early trade today.
