Benchmark equity indices Sensex and Nifty surged over 1 per cent on Monday, driven by a sharp correction in crude oil prices and a rally in global markets amid improving sentiment surrounding the US-Iran negotiations.
An appreciating rupee against the US dollar and intense buying in banking and financial stocks also bolstered sentiment, traders said.
The 30-share BSE Sensex jumped 1,073.61 points, or 1.42 per cent, to settle at 76,488.96. During the day, it soared 1,143.72 points, or 1.51 per cent, to 76,559.07.
A total of 2,785 stocks advanced, while 1,535 declined and 211 remained unchanged on the BSE.
The 50-share NSE Nifty surged 312.40 points, or 1.32 per cent, to end at 24,031.70.
"Sentiment was primarily driven by optimism surrounding a potential US-Iran peace agreement, which triggered a sharp correction in crude oil prices. Brent crude slipped below the USD 100 per barrel mark for the first time in over two weeks and gradually inched toward the USD 95 level.
"Additionally, the outperformance of private banking majors, supportive earnings announcements, and the rupee's further strengthening against the US dollar aided the recovery," Ajit Mishra, SVP, Research, Religare Broking Ltd, said. From the 30-Sensex firms, Bajaj Finance, Larsen & Toubro, HDFC Bank, Eternal, Bajaj Finserv, and Kotak Mahindra Bank were among the biggest winners.
In contrast, Infosys, Tata Consultancy Services, Sun Pharma and Hindustan Unilever were the laggards.
Brent crude, the global oil benchmark, tanked 5.52 per cent to USD 97.82 per barrel.
The rupee appreciated 35 paise to close at 95.25 (provisional) against the US dollar on Monday, registering the third straight session of gain.
The US has made significant progress in negotiations with Iran to reopen the Strait of Hormuz, but President Donald Trump is maintaining a cautious approach and will not accept a bad deal, Secretary of State Marco Rubio said on Monday.
"Markets witnessed strong positive momentum, driven by a correction in crude oil prices amid rising expectations of a potential US-Iran deal. Global sentiment improved on reports of progress towards reopening the Strait of Hormuz, although credibility remains uncertain given frequent shifts in developments," Vinod Nair, Head of Research, Geojit Investments Limited, said.
The BSE SmallCap Select index jumped 1.18 per cent, and the MidCap Select index climbed 0.92 per cent.
