Sensex Crashes 1,092 Points on Weak Monsoon, Iran Tensions, May 30

India’s benchmark indices fell sharply on May 29, 2026, as three major headwinds hit markets. The Sensex dropped 1,092 points to 74,775.74, while the Nifty 50 fell 359 points to 23,547.75. Weak monsoon forecasts, foreign investor selling, and uncertainty over a US-Iran peace deal triggered broad-based selling across Dalal Street, erasing nearly 5 lakh crore rupees in investor wealth.

Monsoon Forecast Triggers Agricultural Concerns

The India Meteorological Department lowered its monsoon rainfall forecast to 90% of the long-term average, down from 92% in its first forecast. Both readings fall under the “below-normal” classification. The agency expects weak El Nino conditions to develop in June, strengthening through the monsoon season. Lower rainfall threatens kharif sowing, reservoir levels, and agricultural output in 2026-27, raising inflation risks for food prices.

Foreign Investors Pull Out Amid Geopolitical Risk

Foreign institutional investors (FIIs) sold aggressively on Friday as uncertainty over a US-Iran peace deal persisted. While reports emerged that the United States and Iran were working toward extending the current ceasefire, no official confirmation came from Washington. Investors avoided new risks heading into the weekend. This selling pressure, combined with profit-taking in the final hour, pushed the Nifty below 23,550.

Sector-Wide Losses, IT Holds Ground

Power Grid Corporation fell 4.11% to close at 287.80 rupees, while IndiGo dropped 3.28% to 4,420 rupees on concerns over rising aviation fuel costs. Oil and Natural Gas Corporation declined 3.01% to 265.80 rupees. The Nifty Bank index fell 1.12% to 54,239.20. Tech stocks bucked the trend, with Tech Mahindra rising 1.68% and HCL Technologies gaining 1.44%, as global AI demand lifted sentiment.

Oil Prices Fall, But Remain Elevated

Brent crude fell 1.8% to $92.10 a barrel as ceasefire talks eased some energy concerns. However, prices remained well above the $70 level seen before the conflict began in late February. Higher oil prices have disrupted shipments through the Strait of Hormuz, which handles roughly one-fifth of global oil and natural gas trade. Elevated fuel costs continue to pressure airline margins and consumer spending across India.

Final Thoughts

India’s markets face a perfect storm of weak monsoon forecasts, geopolitical uncertainty, and FII outflows. With the Sensex down 1.44% and the Nifty below 23,550, investors should monitor monsoon updates and US-Iran developments closely before adding exposure.
