India's stock market is anticipated to open lower today as investors exercise caution due to escalating tensions in the Iran war. The Nifty 50 index is expected to open near its previous close of 22,713.1 points, with GIFT Nifty futures trading at 22,725. This cautious sentiment follows US President Donald Trump's stern warning to Iran regarding the reopening of the Strait of Hormuz, a crucial route for approximately 20% of global oil and natural gas supplies, which has been largely shut down since the onset of the conflict five weeks ago. Last week, the Nifty 50 and Sensex indices fell by 0.5% and 0.4%, respectively, marking a sixth consecutive week of losses as the ongoing war and resulting energy crisis continue to impact market dynamics. Brent crude prices have surged above $110 per barrel, further complicating the market outlook.
