Why Did the Sensex Crash? Four Key Factors Behind Monday's Sell-Off

Indian equity markets experienced a brutal sell-off on Monday, with the benchmark Sensex shedding over 1100 points and the Nifty falling by 360 points. Investors faced a significant bloodbath, and the combined market capitalization of BSE-listed companies plummeted by approximately 8.92 lakh crore rupees, shrinking to around 474 lakh crore rupees. But what triggered this sharp decline? Let's break down the four primary reasons behind Monday's market crash.

1. Escalating Iran-US Tensions

The ongoing conflict between Iran and the United States cast a long shadow over global markets, and Indian equities were no exception. The US rejection of a ceasefire proposal has amplified concerns that tensions in West Asia could persist longer than initially anticipated. This heightened geopolitical uncertainty not only dims the prospects for a near-term diplomatic resolution but also increases the risk of prolonged disruptions to oil supplies and a subsequent surge in commodity prices. Adding to the unease, Saudi Arabia reported intercepting Houthi drones targeting Riyadh and a missile aimed at the capital city, underscoring the volatile situation.

2. Surging Crude Oil Prices

Crude oil prices saw a significant jump on Monday, with WTI crude crossing the $93 per barrel mark and Brent crude exceeding $106 per barrel. This recovery in oil prices came after President Donald Trump's rejection of Iran's latest proposal. The market is also grappling with concerns over the Houthi movement potentially taking control of the Bab el Mandeb Strait, a crucial shipping route for Saudi oil. Recent attacks on oil pipelines have fueled fears of sustained high oil prices, sending a wave of panic through the financial markets.

3. US Bond Yields and FII Outflows

A sharp rise in US bond yields put considerable pressure on equity markets worldwide, including India. The yield on the benchmark US 10-year Treasury note climbed to a fresh multi-year high, exceeding 5.2% – the highest level seen since 2004. When bond yields surge, investors often tend to pull money out of riskier emerging market equities, like those in India, and redirect it into US bonds where higher interest rates offer more attractive returns, often denominated in dollars.

This trend was evident in foreign investor activity. Foreign Institutional Investors (FIIs) continued their selling spree in Indian equities, offloading shares worth 3,694 crore rupees on Friday alone. For the entire month of September, total equity outflows through exchanges have already reached a staggering 25,682 crore rupees so far.

4. Weakening Rupee Factor

Adding to the market's woes, the Indian rupee depreciated by 20 paise, closing at 95.95 against the US dollar. This weakening was driven by a stronger dollar and the unabated continuation of foreign fund outflows. The ongoing West Asia conflict further exacerbated these pressures. As India is a significant importer of crude oil, a depreciating rupee places immense pressure on the country's import bill, creating a ripple effect across the economy and the stock market.

Will the Trend Continue?

Analysts suggest that the current trend of market pressure is likely to persist into the coming week. The ongoing tensions in the Middle East remain the central driver of this market downturn, and these geopolitical concerns are expected to linger. Consequently, earnings for Indian equities are likely to remain under pressure.

A significant factor to watch will be the extent of further withdrawals by FIIs from the Indian market. Their actions will play a crucial role in determining the near-term trajectory of the Nifty and Sensex.
