The rupee rallied 53 paise -- its best single-day gain in over 11 months -- to close at an over one-month high of 78.53 against the US dollar on Tuesday.
Persistent foreign fund inflows into capital markets, softening crude oil prices and a weak US dollar in the global markets boosted the local currency.
The rupee, which plummeted to a lifetime low of 80.06 last month, made a spirited recovery in the past four sessions as FIIs returned to capital markets and crude oil prices fell below USD 100 per barrel mark.
Increased risk appetite on hopes of a slow pace of tightening by the US Federal Reserve has also strengthened the rupee sentiment.
The rupee has gained 138 paise or 1.73 per cent against the US dollar in the four days to Tuesday to regain the 78 level.
At the interbank forex market, the local unit opened strong at 78.96 against the greenback and witnessed an intra-day high of 78.49 and a low of 78.96 on Tuesday.

The Indian rupee has perked up to four-week highs, after seven months of successive decline as there has been a clear shift in sentiments, and investors are no longer seeking safety in the US dollar, which has led to renewed inflows in the domestic markets, Sugandha Sachdeva, Vice President - Commodity and Currency Research, Religare Broking Ltd, said.
"Largely it was the tone of the Fed Chair, where he sounded less hawkish and indicated a slow pace of tightening which has improved risk appetite in the markets. Besides, there were visible signs of exhaustion in the dollar index around the 109 mark which prompted a sell-off in the greenback, while aiding the recovery rally in the Indian rupee," Sachdeva added.
A decline in crude prices below USD 100 a barrel, amid weakening demand as well as a ramp-up in output from Libya, has further eased concerns about the widening current account deficit.
"The focus is now on three key events scheduled for the week -the OPEC+ meeting, RBI monetary policy outcome, and the US jobs report that will provide further cues and dictate the trend for the domestic currency," Sachdeva noted.

Going ahead, the bias remains downward as the pair is closing below 50 days' simple moving average and a level below 78.50 will give way for 77.60. "However, one should adjust their position as per the geopolitical updates from US-China", he added.
