Indian benchmark indices closed sharply lower on Monday, dragged down by a broad-based sell-off in banking, auto, and consumer stocks. Investor sentiment remained subdued amid escalating tensions in the Iran-Israel conflict, elevated crude oil prices, and the rupee hitting fresh record lows. The Nifty declined 601.85 points, or 2.6%, to settle at 22,512.65, while the Sensex dropped 1,836.57 points, or 2.46%, to end at 72,696.39.
