Strait of Hormuz Blocked: What the US-Iran War Means for India's Petrol, LPG and Economy

Crude oil is hovering around $108 a barrel. Petrol in India is above Rs 103 per litre. And the world's most important oil shipping lane has been operating at roughly 5 per cent of its normal traffic for the past two months.

The Strait of Hormuz crisis 2026 is not just a geopolitical headline from a distant war. For India, it is arriving at the pump, in the kitchen gas cylinder, in airline ticket prices, and in the government's growth forecast. The Indian Finance Ministry has already warned that its 7.0 to 7.4 per cent GDP growth target for the year faces "considerable downside risk" because of the energy disruption flowing directly from this conflict.

Here is the full picture of what is happening, why it matters specifically for India, and what comes next.

What Is the Strait of Hormuz and Why Does Its Closure Shake the World

The Strait of Hormuz is a narrow waterway, just 24 miles across at its tightest point, sitting between Iran to the north and Oman to the south. Before this crisis, around 3,000 vessels passed through it every month. It carried roughly 20 per cent of the world's seaborne oil trade and 20 per cent of global liquefied natural gas. In simple terms, one-fifth of the world's oil moved through a channel narrower than many Indian rivers.

On February 28, 2026, after the United States and Israel launched military strikes on Iran, the Iranian Revolutionary Guard Corps declared the Strait closed and began attacking merchant vessels attempting to transit it. Since then, shipping traffic has collapsed to around 154 vessels in the entire month of March , down from the 3,000 per month average. That is a 95 per cent reduction. Major shipping companies, including Maersk, CMA CGM, and Hapag-Lloyd, suspended operations through the strait entirely.

On April 13, the United States responded with a counter-blockade, ordering its Navy to prevent ships from entering or leaving Iranian ports. The result is what analysts are now calling a dual blockade , Iran blocking the strait from inside, and the US blocking Iranian ports from the Arabian Sea. The Strait is, for practical purposes, closed to normal commerce.

India Is Caught Directly in the Middle , Here Is How

India imports more than 85 per cent of its crude oil needs, roughly 5.5 million barrels per day, making it the world's third-largest oil importer. A very large share of that oil historically came through the Gulf region, transiting the Strait of Hormuz.

The crisis has hit India in three separate ways simultaneously, and each one compounds the next.

First, Iranian oil is now inaccessible. India had just resumed importing Iranian crude for the first time in seven years, scrambling to diversify its supply as global markets tightened due to the war. The US blockade cut that supply off within weeks of India beginning those imports.

Second, Russian oil access has been restricted. For the past year, India has relied heavily on discounted Russian crude, buying 1.5 million barrels per day in March 2026 after the US issued a temporary waiver allowing it. That waiver expired on April 11. Without it, India cannot freely purchase Russian oil without risking secondary sanctions from Washington. Energy analyst Mukesh Sahdev told CNBC directly: India is facing a mounting supply squeeze "with the loss of Iranian barrels, plus not getting the Russian barrels.

Third, Gulf producers have cut output. Saudi Arabia, UAE, Kuwait, and Iraq collectively reduced production by at least 10 million barrels per day by mid-March because Iranian attacks on regional infrastructure and shipping made normal operations dangerous. The countries that India would normally turn to for alternative supply are themselves producing less.

What This Means for Petrol, LPG and Inflation in India

Brent crude surged past $120 per barrel immediately after the strait closed in early March, before settling around $108 to $110. That is still approximately 60 to 70 per cent higher than prices a year ago.

India's retail petrol prices have crossed Rs 103 per litre in major cities. Diesel sits above Rs 90. LPG cylinder prices have risen to Rs 912.50. These are not sharp, sudden jumps because the government has historically cushioned fuel prices through the Oil Marketing Companies, absorbing losses rather than passing them fully to consumers. But OMC finances are under severe strain , one financial channel described their condition as "near ICU."

Aviation fuel costs have surged due to both the oil price spike and the rerouting of flights away from Middle East airspace, which has been disrupted by the conflict. Airlines are adding hundreds of kilometres to journeys that previously flew over Iran and the Gulf, burning more fuel per flight. Passengers are already seeing higher airfares.

Retail inflation ticked up to 3.4 per cent in the latest reading, with fuel and transport costs contributing even as food inflation stayed relatively contained.

India's Diplomatic Tightrope , Caught Between Washington and Energy Needs

India's position in this crisis is genuinely uncomfortable. It is not a party to the US-Iran conflict. It has no strategic interest in a war that is disrupting its energy supply. But it finds itself constrained by both sides.

Washington expects India to respect the sanctions architecture against Iran and not undermine the blockade. At the same time, Washington's own policies , the expiry of the Russian oil waiver, pressure not to buy Iranian oil , are removing India's cheapest and most accessible supply alternatives precisely when global prices are at their highest.

As Samir Kapadia of the Vogel Group put it to CNBC, "I feel bad for the Indian government. They're on a seesaw right now, trying to balance the expectations of the United States. There is no easy out for India."

India has reportedly been exploring alternative supply routes. Gulf countries are reviving the IMEC corridor concept , a trade and energy route that runs from India through the Gulf and then to the Israeli port of Haifa and on to Europe, bypassing the Strait of Hormuz entirely. Saudi Arabia is also reportedly looking at expanding its 1,200-kilometre East-West pipeline that delivers oil to the Red Sea port of Yanbu, a route that avoids Hormuz. These alternatives take years to scale and cannot solve the immediate problem.

When Could the Strait Reopen and What Does India Need to Watch

The strait's reopening is the central demand of every diplomatic negotiation currently underway. Iran says it will not reopen until the US ends its naval blockade. The US says it will not lift the blockade until Iran agrees to a nuclear deal. Trump, as of late April, stated the blockade will remain in place until Iran agrees to the terms.

A temporary ceasefire agreed on April 8 briefly offered hope, but collapsed within days. On April 17, Iran announced the strait would be open during the truce; on April 18, it closed it again. The situation remains volatile and fluid.

For India, the practical watchpoints are: whether the US extends the Russian oil waiver again, whether India secures alternative long-term supply contracts with non-Gulf producers, and whether any diplomatic breakthrough emerges from the Pakistan-mediated talks between the US and Iran that are still nominally ongoing.

Closing Thoughts

A waterway 24 miles wide is holding the global economy hostage. That is not hyperbole , it is the current arithmetic of oil markets.

For ordinary Indians, this crisis is arriving not as news but as a number on a petrol pump display and a slightly heavier grocery bill. The government has limited tools to absorb it indefinitely. And the war that caused it shows no clear signs of ending on a timeline that Indian energy planners can plan around.

Energy security has quietly become one of the most consequential geopolitical questions facing India. The Strait of Hormuz crisis of 2026 is forcing that conversation into the open, whether anyone is ready for it or not.
