The rupee on Wednesday climbed 15 paise to Rs 46.91 a dollar at the Interbank Foreign Exchange market in early trade on capital inflows into equities by foreign funds.
Dollar's losses against other major currencies also supported the Indian rupee.
Dealers said fresh capital inflows into equities by foreign funds kept the rupee sentiment firm.
Besides, firming Asian currencies against the dollar also provided some support to the rupee.
The rupee had ended 15 paise lower at over five-week low of Rs 47.06/07 against the dollar in the previous session.
Meanwhile, the Bombay Stock Exchange index Sensex rose by 119.90 points to 18,091.02 points, a jump of 0.66 per cent in the opening trade today.
