Forex dealers said that besides selling of the American greenback by exporters and banks, weakness in the dollar against other currencies overseas supported the rupee.
Further, a higher opening in the domestic equity market influenced the rupee uptrend, they added.
Yesterday, the rupee had ended marginally lower by two paise at 68.20 despite the outlook for the dollar remaining lacklustre.
Meanwhile, the benchmark BSE Sensex rose 100.36 points, or 0.37 per cent, at 27,217.70 in early trade today.
