Fresh dollar selling by exporters and a weak American currency in the overseas markets also aided the rupee rise.
At the Interbank Foreign Exchange market, the rupee commenced strong at 62.25 a dollar from the previous close of 62.42. It, however, fell back to a low of 62.3650 on weakness in local stocks around noon and dollar demand from importers.
A smart rebound in share markets on late buying and renewed dollar selling by exporters helped the rupee to rise to a high of 61.92, before settling at 61.93 -- a rise of 49 paise or 0.79 per cent.
Today's 49 paise gain is the best since January 28 (59 paise) while the closing level matches 61.93 on January 23.
