Why did the Nifty and Sensex fall today?
The Nifty 50 fell 0.39% to 22,600 at the close on Friday, October 23, 2026, while the Sensex also remained under selling pressure. After earlier slipping below 72,900, the index closed at 73,123.83, falling 0.17%.

Higher crude prices threaten India's import bill, inflation and corporate profitability, weighing on investor sentiment.
Brent Crude Near $114 Weighs on the Share Market
Fresh attacks involving Saudi Arabia have heightened fears of prolonged disruptions to global energy supplies. As India imports most of its crude oil requirements, elevated prices could increase transportation and manufacturing costs. This may also limit the Reserve Bank of India's flexibility to reduce interest rates.
Why FII Selling Added Pressure on the Nifty and Sensex
Foreign institutional investors sold Indian equities worth ₹3,459 crore on October 22, while domestic institutions purchased ₹2,891 crore. Global sentiment also weakened after the US Nasdaq Composite declined 2.6% overnight. The combination of foreign selling, expensive crude and weak international markets accelerated the domestic decline.

At the close, the Nifty Metal, PSU Bank and Realty indices declined more than 2%, while Pharma, Media, Financial Services and Bank fell more than 1%.
