Indian equity indices ended lower on Monday as geopolitical tensions between the U.S. and Iran pressured the market [1, 2].

The decline reflects the sensitivity of the Indian economy to global crude oil prices, which typically rise during Middle East conflicts and increase domestic inflationary pressure.

Selling pressure concentrated in the IT, realty, metal, and FMCG sectors [1, 2]. The Nifty 50 fell below 24,200 [1], eventually closing at 24,154.90, a drop of 132.75 points [6]. The index had opened the session down 50 points [4].

The Sensex experienced a similar decline, dropping 370 points at the open [4]. It fell over 500 points during the session [3], ultimately closing at 77,235.46, which represented a loss of 492.70 points [6].

Several high-profile stocks contributed to the losses. Top losers included Asian Paints, Infosys, HCLTech, Wipro, and Tata Motors Passenger Vehicles [1, 2]. The IT index specifically fell 1.9 points [1, 2].

Some sectors remained resilient against the global cues. Gainers included Axis Bank, Max Healthcare, Grasim Industries, M&M, and Power Grid Corp [1, 2]. The auto, media, and pharma sectors all closed the day in positive territory [1, 2].

Market volatility was preceded by early indicators from the Gift Nifty, which traded around 24,320, down 72.70 points from its previous close [9]. Analysts said heightened U.S.-Iran conflict tensions and the resulting rise in Brent crude prices were the primary catalysts for the sell-off [3, 8].

Indian equity indices ended lower on Monday as geopolitical tensions between the US and Iran pressured the market.

The market reaction underscores India's vulnerability to external shocks, particularly energy price spikes. Because India imports a vast majority of its crude oil, instability in the Strait of Hormuz or direct conflict between the US and Iran directly impacts trade balances and corporate margins, leading investors to rotate out of volatile sectors like IT and metals into more defensive positions.
