Sensex, Nifty close lower as Middle East tensions and high crude oil drag markets

MUMBAI: Indian equity benchmarks closed lower on October 23, 2026, as the Nifty 50 slipped and broader markets faced selling pressure amid escalating geopolitical tensions in the Middle East and a rise in global crude oil prices.

The BSE Sensex declined from its previous closing of 73,249.39 to settle at 73,123.83. On the National Stock Exchange, the Nifty 50 index closed at 22,600.00, down 87.65 points or 0.39 per cent. Market breadth reflected widespread pessimism, with 3,011 stocks declining against 623 advances, while 655 stocks hit their 52-week lows.

The sell-off was pronounced in the mid and small-cap segments. The Nifty Midcap 100 index fell 2.21 per cent to 55,800.65, and the Nifty Smallcap 100 index dropped 2.94 per cent to 17,739.45. The Nifty Alpha 50 index also saw a decline of 2.81 per cent. Sectorally, the Nifty Bank index shed 1.16 per cent to 54,287.35, while the Nifty Auto, Nifty FMCG, and Nifty IT indices also ended in negative territory. The overall market capitalisation on the NSE stood at Rs 447.97 lakh crore, with total equity market turnover at Rs 1,23,123.89 crore.

Market participants attributed the correction to rising geopolitical risks. As reported by NDTV Profit, Brent crude topped $110 per barrel following fresh attacks in Saudi Arabia and escalating US-Iran tensions, raising concerns over global oil supplies. Banking stocks and energy-sensitive sectors bore the brunt of the high oil price environment, as reported by The Economic Times, which noted that elevated energy costs could impact corporate margins.

The rise in crude oil prices poses a challenge to India's macroeconomic stability, potentially widening the current account deficit and increasing inflationary pressures. For a net oil-importing nation, sustained high energy costs typically lead to higher input costs for corporations and reduced consumer spending. This vulnerability explains the substantial outflow from mid-cap and small-cap stocks, which are sensitive to domestic economic conditions. The fact that 655 stocks hit their 52-week lows indicates that the selling pressure is widespread across the market.

Looking ahead, the trajectory of the Indian stock market will depend on global geopolitical developments and crude oil price movements. Investors will monitor foreign institutional investor activity, currency fluctuations, and festive season demand data to assess whether the current market valuations offer a buying opportunity or if the correction will continue.
