Indian stock markets experienced a significant upswing on Tuesday, marking the third consecutive day of gains. The BSE Sensex surged by 753.03 points, or 0.96%, to close at 79,273.33, while the NSE Nifty climbed 211.75 points, or 0.87%, ending at 24,576.60. This positive momentum was largely attributed to a drop in crude oil prices and increasing optimism regarding peace talks between Iran and the United States. Brent crude, the global benchmark, traded 0.75% lower at $94.76 per barrel. Notably, Trent led the gains among Sensex firms with a 3.55% increase, while major contributors included Hindustan Unilever, ICICI Bank, Bajaj Finance, HDFC Bank, and Axis Bank. In contrast, Bharat Electronics, Titan, Reliance Industries, and NTPC saw declines. Broader markets also showed strength, with the BSE MidCap Select index rising by 0.73% and the SmallCap Select index by 0.29%. Analysts noted that easing geopolitical tensions, particularly regarding the US-Iran situation, boosted investor confidence, while cooling crude prices alleviated inflation concerns for India, an oil-import-dependent economy. Foreign Institutional Investors (FIIs) sold equities worth ₹1,059.93 crore on Monday, but the overall market sentiment remained buoyant as investors positioned themselves for potential positive developments in the ongoing negotiations.
