Bearish Risk: Nifty Plunges on US-Iran Tensions, Oil Spike; OMCs

Analyzing: Why is stock market crashing today? Sensex plunges 1,600 pts, Nifty below 23,600. 7 key factors explained by et_markets · 13 Apr 2026, 9:29 AM IST (about 7 hours ago)

What happened

Indian benchmark indices, Sensex and Nifty, experienced a sharp decline of nearly 2% each, with Nifty falling below 23,600. This significant market correction was primarily triggered by escalating geopolitical tensions between the US and Iran, leading to threats of a blockade in the Strait of Hormuz and a subsequent surge in global crude oil prices above $100 per barrel.

Why it matters

The rise in crude oil prices is a critical concern for India, a major oil importer, as it can lead to increased inflation, higher current account deficit, and potential interest rate hikes by the RBI. Geopolitical instability also dampens global investor sentiment, leading to FII outflows and increased volatility in emerging markets like India, impacting overall economic stability and corporate earnings outlook.

Impact on Indian markets

Upstream oil exploration companies like ONGC are likely to see a positive impact due to higher crude realizations. However, oil marketing companies (OMCs) such as IOC, BPCL, and HPCL will face negative pressure as increased input costs may squeeze their marketing margins. Energy-intensive sectors like aviation and logistics will also be negatively impacted by rising fuel expenses, while the broader market will experience selling pressure across sectors due to risk aversion.

What traders should watch next

Traders should closely monitor developments in the US-Iran situation and global crude oil prices. Key levels for Nifty and Sensex will be crucial to watch for potential reversals or further downside. Any statements from the RBI regarding inflation or interest rates, and FII flow data, will also provide important cues for market direction.

Key Evidence

  • Indian equity markets experienced a sharp decline on Monday, with Sensex and Nifty falling nearly 2% each.
  • The downturn was driven by escalating US-Iran tensions.
  • A blockade threat in the Strait of Hormuz contributed to the market fall.
  • Crude oil prices surged above $100 per barrel.
  • Global markets also tumbled, signaling a bearish sentiment.

As an oil marketing company, higher crude oil prices increase input costs, potentially squeezing marketing margins if retail fuel prices are not fully adjusted.
