How Iran war is keeping oil prices elevated despite measures by US, other global powers

Ever since the beginning of the Iran war, the price of oil and gas has soared.

The Strait of Hormuz has remained closed as tankers full of crude are stranded in the Persian Gulf. US President Donald Trump and other world leaders have been trying their best to keep a lid on the price of oil.

It began with the members of the International Energy Agency, which comprise 32 nations, announcing that they would release 400 million barrels of oil – the biggest such reserve release in its history.

Trump is also tapping into the US’ Strategic Petroleum Reserve and sanctions on Russian and Iranian crude. He is also temporarily waiving the Jones Act, a maritime law that requires ships carrying goods between US ports to be US-flagged.

However, the price of crude oil remains over $100 (Rs 9,321) a barrel. In America, gas is selling for $4.06 (Rs 378.43) a gallon on average.

Experts say that these measures are falling short.

“They’re all incremental,” said Mark Barteau, professor of chemical engineering and chemistry at Texas A&M University. “You’re talking about these different patches being at the level of maybe 1 to 2 million barrels a day each, and you’ve got to get to 20, so it’s hard to see those actually adding up to the numbers that are needed. And then the question is, how long can you sustain those?”

Strait of Hormuz remains closed

Before the war began, roughly 15 million barrels of crude oil and 5 million barrels of oil products passed daily through the Strait of Hormuz, the narrow mouth of the Persian Gulf, amounting to about 20 per cent of global oil consumption, according to the International Energy Agency.

In addition to that loss, some oil-producing nations in West Asia have halted oil production because they can’t ship fuel out of the Gulf and their storage tanks are full. That’s taken about 10 million more barrels per day off the market, the IEA said.

Then there are the eight countries around the Persian Gulf that together hold about 50 per cent of global oil reserves. Under normal circumstances, they coordinate closely to raise or lower their output to keep prices steady, said Jim Krane, energy research fellow at Rice University’s Baker Institute. Usually Saudi Arabia steps in to bring spare oil to market and calm things down, he said.

“But all of that spare capacity is also bottled up inside the Persian Gulf right now and it can’t get to market either,” Krane said. “So the main emergency response system that we have is also blocked.”

The IEA said in its recent report that “the resumption of transit through the Strait of Hormuz is the single most important action to return to stable oil and gas flows and reduce the strains on markets and prices.”

Barring that, world leaders are grasping for ways to free up more oil.

Workarounds remain limited

Some nations have found workarounds to move oil out of the Gulf. Saudi Arabia is using its East-West pipeline, which stretches from the Persian Gulf to the Red Sea, to transfer about 5 million barrels per day out of the Gulf, said Michael Lynch, distinguished fellow at Energy Policy Research Foundation, a non-partisan institution focused on energy and economics. But the nation was already using that pipeline to transport oil, so it doesn’t have a lot of spare room to move oil from stranded tankers.

Trump also temporarily lifted sanctions on approximately 140 million barrels of Iranian oil that was already in transit. But that didn’t add oil to the market — it just widened the pool of potential buyers, said Daniel Sternoff, senior fellow at the Columbia Center on Global Energy Policy.

Typically, most Iranian oil was bought by private refiners in China, who purchased it at a steep discount, Sternoff said. But with sanctions lifted, others could scramble to buy the oil, which in turn raises its price to the benefit of Iran, he said.

“As soon as you are moving to waive sanctions on your adversary with whom you’re fighting a military conflict, to do something in their benefit, it just shows you that you are running out of options to try to prevent a rise in the price of oil,” Sternoff said.

The decision to lift sanctions on Russian oil could have more impact, because Russia had been storing unpurchased oil in tankers, Sternoff said. “By waiving sanctions, it will allow those barrels to clear.”

Trump’s temporary waiver of the Jones Act to allow foreign ships to temporarily transport goods between US ports could potentially help ease natural gas prices by enabling companies to more efficiently ship liquefied natural gas from the Gulf Coast to New England.

But experts don’t expect the waiver to significantly impact the price of oil or gasoline. “It’s helpful, but not a game changer,” Lynch said.

US can’t solve the issue

The US is a major oil producer and exports more oil than it imports. But like any other oil-producing nation, it can’t just ramp up production instantly to fill the void.

“If the US were to try to make up the global shortfall, we would need to nearly double our production,” Barteau said. “We couldn’t drill wells that fast even if we wanted to.”

Increasing domestic production by even 1 million barrels per day, a feat the US accomplished during the shale boom, would be hard to duplicate, Lynch said.

“If we run every drilling rig right now, what happens a week from now when the war is over and the price goes back down $20 (Rs 1,864)?” Lynch asked. “People don’t want to develop long-term production based on a short-term price spike.”

Halting exports and using that oil within the US wouldn’t bring down gasoline prices either, experts say.

For one, oil is traded on a global market, so events happening halfway around the globe impact prices for everyone.

In addition, the US doesn’t produce enough of the type of oil its refineries process. It produced about 13.7 million barrels per day of oil at the end of 2025, according to the Energy Information Administration. And refineries processed about 16.3 million barrels per day that year, relying on imports to fill in the gaps, according to the American Fuel and Petrochemical Manufacturers (AFPM), a trade association.

That’s because nearly 70 per cent of US refineries are set up to process heavy, sour crude, according to AFPM. But much of the oil produced in the US is light, sweet crude, which was unlocked during the shale revolution.

“They need different crudes than the ones that are being produced right next to them now,” Krane said. As a result, just 60 per cent of the crude oil processed in US refineries is extracted domestically, according to the AFPM. And retooling domestic refineries would cost billions of dollars, the group said. It also would require shutting down the refinery for a period of time, which generally raises gasoline prices.

“A lot of people like the IEA are making the point that this is the biggest oil crisis ever, which is partly true, partly an exaggeration, depending on how you count things,” Lynch said. “A lot of it has to do with how long does this last … if it goes on for another six weeks we get to be in some serious trouble.”

FAQs

1) Why are oil prices still rising despite global intervention?
Because a large portion of global supply is physically blocked in the Persian Gulf, and stopgap measures like reserve releases only add limited volumes.

2) How important is the Strait of Hormuz to global oil supply?
It handles about 20 per cent of global oil consumption, making it the most critical chokepoint in the energy market.

3) Can the US increase oil production to stabilise prices?
Not quickly. Scaling production takes time, infrastructure, and investment, and cannot offset a sudden global supply shock in the short term.
