Rising crude oil prices and strengthening dollar, however, weighed on the Indian currency, according to forex traders.

Later, the rupee was trading at 82.73 against the dollar, registering a gain of 7 paise from its previous close.

On Tuesday, the rupee closed at 82.80 against the US dollar.

"Yesterday, in the latter part of the day, dollar fell sharply and that led to gains not only in major crosses but also in commodities," Gaurang Somaiya, Forex and Bullion Analyst at Motilal Oswal Financial Services, said.

On the domestic front, GDP numbers will be important to watch and better-than-expected numbers could support the rupee, he said. GDP numbers are scheduled to be released on Thursday.
