A fall in dollar against major world currencies globally boosted the rupee, currency traders said.
The dollar fell to its weakest level since 2015 as experts warn that Hurricane Irma could have devastating impact on the US. The powerful storm has left a trail of death and destruction in the Caribbean and is headed towards the US.
The European Central Bank also raised its economic growth forecast for this year, which boosted the euro.
Yesterday, the rupee had closed five paise higher at 64.05 against the American unit.
Meanwhile, the benchmark BSE Sensex was trading higher by 100.96 points, or 0.31 per cent, at 31,763.70 in early session today.
