Mumbai: The rupee appreciated 12 paise to 81.96 against the US dollar in early trade on Friday, as a strong opening in domestic equity markets and a weaker greenback against major rivals overseas strengthened investor sentiments.

In the initial trade, the domestic unit was moving in a narrow range of 81.92-81.97 against the American currency.
In the previous session on Thursday, the rupee had settled at 82.08 against the dollar.
