Indian Markets Decline on US-Iran Tensions, Rising Crude Prices

Indian equity benchmarks, the NIFTY50 and SENSEX, experienced a significant downturn on Friday, May 8, 2026, opening notably lower and continuing to trade in negative territory throughout the day. The BSE Sensex initially dropped by 290.84 points, or 0.37%, to 77,553.68 at 9:22 am, while the Nifty 50 eased 95.15 points, or 0.39%, to 24,231.50 at the same time. As the trading session progressed, the selling pressure intensified, with the Sensex falling as much as 553 points and the Nifty touching an intraday low of 24,158. Mid-day figures indicated the Sensex was down 417.06 points, or 0.54%, at 77,427.46, and the Nifty 50 had declined by 116.20 points, or 0.48%, to 24,210.45 by 11:43 am. The primary driver behind this market weakness was the fresh escalation of tensions between the United States and Iran, which spooked global investors and led to a surge in crude oil prices. Reports confirmed renewed fighting between US and Iranian forces near the Strait of Hormuz late on Thursday, May 7, testing a month-long fragile ceasefire. Both nations accused each other of violating the agreement, with Iran alleging US strikes on its vessels and civilian areas, while the US military stated its strikes were in retaliation for Iranian attacks on three US destroyers transiting the Strait of Hormuz. Despite the renewed clashes, US President Donald Trump insisted the ceasefire remained intact, describing the US strikes as a "love tap". This geopolitical instability directly impacted global crude oil prices, which moved above $100 per barrel, with Brent crude futures gaining $1.20, or 1.2%, to $101.26 a barrel, and US West Texas Intermediate (WTI) crude rising 85 cents, or 0.9%, to $95.66 a barrel on May 8. This marks a significant increase from approximately $70 a barrel before the war began in late February. The rising crude prices fuelled concerns about inflation and economic growth, particularly for oil-importing nations like India. Adding to the negative sentiment were the cues from Wall Street, which closed lower on Thursday, May 7. The S&P 500 slipped 0.4% to 7,337.11, the Dow Jones Industrial Average fell 0.6% to 49,596.97, and the Nasdaq Composite eased 0.1% to 25,806.20. This decline was attributed to the volatile crude oil prices and the ongoing uncertainty surrounding the Middle East conflict. Asian markets largely followed suit, with Japan's Nikkei, South Korea's Kospi, Hong Kong's Hang Seng, and China's Shanghai Composite all trading lower on Friday. Foreign Institutional Investors (FIIs) continued their cautious stance in the Indian markets, selling equities worth ₹340.89 crore on Thursday, May 7. In contrast, Domestic Institutional Investors (DIIs) provided some support by buying stocks worth ₹441.07 crore on the same day. This mixed activity reflects the broader apprehension among international investors regarding global geopolitical risks. According to NSE data, FIIs have been net sellers, offloading shares worth ₹2,06,180 crore so far this year. Sectoral performance within the Indian market on May 8, 2026, saw broad-based selling pressure. Rate-sensitive and cyclical sectors were particularly affected. Nifty Private Bank, Nifty Financial Services, Nifty Bank, Nifty PSU Bank, and Nifty Auto were among the worst performers, with declines ranging from 0.61% to 0.83%. Major losers included Coal India, M&M, Axis Bank, HDFC Bank, and Tata Motors. Conversely, the IT and healthcare sectors displayed some resilience and witnessed mild buying interest, providing a partial offset to the overall market decline. Broader markets, including the Nifty MidCap 100 and Nifty SmallCap 100, were trading on a mixed note, with some small-cap indices even showing marginal gains. Market experts like V.K. Vijayakumar, Chief Investment Strategist at Geojit Investments Limited, highlighted that the continuing uncertainty over developments in the Middle East is a key factor keeping markets on edge, and investors can expect continued volatility driven by oil prices and geopolitical headlines. The Indian Rupee also reflected the sentiment, opening lower at 94.58 per US dollar. In conclusion, the Indian stock market's decline on May 8, 2026, was a direct consequence of escalating US-Iran tensions in the Strait of Hormuz, which propelled crude oil prices higher and led to negative cues from Wall Street. While domestic institutional investors offered some counterbalance, the outflow of foreign capital indicated heightened risk aversion amidst the volatile geopolitical landscape.
