The rupee firmed up 5 paise to 63.75 against the US dollar in early trade on Tuesday on fresh selling of the American currency by exporters and banks amid a higher opening in the domestic equity market. Besides, weakness in the dollar against some other currencies overseas and a higher opening in the domestic equity market supported the rupee, forex dealers said.

Yesterday, the rupee faced a temporary hitch and retracted from its two-year high to close at 63.80 a dollar by tumbling 22 paise after the four-day strong rally lost momentum on sharp recovery of the US currency. Meanwhile, the benchmark BSE Sensex rose 70.10 points, or 0.21 per cent, to 32,343.77 in early session.
