Bearish Risk: Iran's Hormuz Blockade Hits Indian Oil, Gas, Fertilizer Stocks
Analyzing: “Iran moves to assert control over Strait of Hormuz while trading strikes with Israel” by et_companies · 28 Mar 2026, 8:16 AM IST (about 1 month ago)
What happened
Iran has asserted control over the Strait of Hormuz, a critical global chokepoint for oil and gas, and is formalizing tolls while engaging in intensified conflict with Israel. This move has already disrupted international flows of crude oil, natural gas, and fertilizers, creating significant uncertainty in global commodity markets.
Why it matters
For India, a major importer of crude oil, LNG, and fertilizers, this development is highly significant. Increased geopolitical risk in the Middle East directly translates to higher import bills, potential supply chain disruptions, and inflationary pressures. This could impact the Indian rupee and the Reserve Bank of India's monetary policy decisions.
Impact on Indian markets
Upstream oil companies like ONGC may see a positive impact from higher crude prices. However, oil marketing companies (OMCs) such as IOC, BPCL, and HPCL will face margin pressure due to increased crude import costs. Fertilizer companies like GSFC and NFL will also be negatively impacted by rising input costs (gas, ammonia). Shipping companies like SCI could face higher operational costs and insurance premiums.
What traders should watch next
Traders should closely monitor the geopolitical developments in the Middle East, particularly any escalation or de-escalation of tensions between Iran and Israel. Watch for global crude oil price movements (Brent crude) and their impact on Indian OMCs' stock performance. Also, observe government interventions regarding fuel price adjustments and fertilizer subsidies, which could mitigate or exacerbate the impact on affected companies.
Key Evidence
- •Iran asserted control over the Strait of Hormuz.
- •Iran is moving to formalise tolls for passage through the Strait.
- •Fighting with Israel intensified across the region.
- •The blockade has disrupted global oil, gas and fertiliser flows.
Affected Stocks
Increased crude oil and gas prices will raise input costs for refining and petrochemicals, though higher product prices could partially offset this. Shipping disruptions also pose a challenge.
Higher global crude oil prices generally benefit upstream oil producers like ONGC, improving their realizations.
As a major oil refiner and marketer, increased crude oil import costs will squeeze margins unless retail fuel prices are adequately adjusted, which is often politically sensitive.
Similar to IOC, BPCL faces margin pressure from higher crude import costs.
Similar to IOC and BPCL, HPCL faces margin pressure from higher crude import costs.
Disruption in gas flows and potential price increases for imported LNG could impact GAIL's gas transmission and marketing business.
Increased fertilizer input costs (natural gas, phosphoric acid, ammonia) due to supply disruptions and higher prices will impact profitability.
Similar to GSFC, NFL will face higher input costs for fertilizer production.
Higher raw material costs for fertilizer production will negatively affect margins.
Increased geopolitical risk and potential for higher insurance premiums or rerouting could impact shipping operations and costs.
