In Wednesday’s session, the rupee had gained 13 paise to close at Rs 45.09/10 against the dollar on the Interbank Foreign Exchange on sustained dollar-selling by exporters.
Dealers said a firming trend in other Asian currencies and sustained dollar inflows mainly kept the rupee sentiment firm.
A higher opening in the stock market also supported the rupee’s rise, they said.
Meanwhile, the Bombay Stock Exchange index Sensex opened 57.10 points, or 0.29 per cent, higher at 20,072.90 in opening trade on Thursday.
