Bearish for OMCs: Brent Crude Surges 9.6% on Iran Attack Reports

Analyzing: Brent crude rebounds 9.6% from day's low to $110 on reports of attack on Iran’s South Pars gas field by livemint_markets · 18 Mar 2026, 8:39 PM IST (about 2 months ago)

What happened

Brent crude oil prices rebounded sharply by 9.6% from their day's low, reaching $110, following unconfirmed reports of an attack on Iran's South Pars gas field. This alleged incident, potentially involving Israel with US consent, signifies a major escalation of geopolitical tensions in the Middle East, directly threatening global energy supplies.

Why it matters

For Indian markets, this surge in crude oil prices is a significant concern as India is a major oil importer. Higher crude prices lead to increased import bills, potentially widening the current account deficit, fueling inflation, and putting pressure on the Indian Rupee. This can also impact the profitability of various sectors due to higher transportation and input costs.

Impact on Indian markets

Upstream oil producers like ONGC (ONGC) are likely to see a positive impact due to higher realizations from crude sales. However, Oil Marketing Companies (OMCs) such as Indian Oil Corporation (IOC), Bharat Petroleum Corporation (BPCL), and Hindustan Petroleum Corporation (HPCL) will face margin pressure as their input costs rise significantly. Reliance Industries (RELIANCE) could see mixed impact, with its upstream segment benefiting but refining margins potentially squeezed.

What traders should watch next

Traders should closely monitor further developments regarding the geopolitical situation in the Middle East and any official confirmations or denials of the attack. Key indicators to watch include crude oil inventory data, statements from OPEC+, and the Indian government's stance on fuel price adjustments. Any sustained rise in crude above $110 could trigger further downside for OMCs.

Key Evidence

  • Brent crude oil prices rose 9.6% from day's low to $110.
  • The surge followed reports of an attack on Iran’s South Pars gas field.
  • Reports suggest Israel, with US consent, targeted the site.
  • The incident escalates tensions and risks global energy security.
