  • Sensex and Nifty Open Higher Despite FPI Outflows and Geopolitical Tensions
    March 18, 2026, 12:41 AM EDT. Indian stock markets started Wednesday on a positive note with the Sensex climbing 296.71 points to 76,367.55 and the Nifty 50 rising 51.75 points to 23,632.90. This resilience comes amid ongoing foreign portfolio investor (FPI) outflows exceeding Rs 70,000 crore and geopolitical uncertainty from the US-Israel-Iran conflict. Sectoral indices showed broad strength: Nifty IT surged over 2.3%, Autos gained 1.38%, and Midcap and Smallcap indices rose firmly. Market experts highlighted the influence of deepening oil market disruptions and an upcoming U.S. Federal Reserve meeting expected to maintain interest rates. Global cues were mixed but mostly positive, with key Asian indexes climbing, except for Hong Kong's Hang Seng. Elevated crude oil at around $103 per barrel and weak gold and silver prices added complexity to the market environment.
