Oil CEOs Say The Iran War Has Permanently Changed Energy Markets

Published May 10, 2026

Summary:
  • Iran's blockade of the Strait of Hormuz has wiped out close to a billion barrels of oil supply.
  • Oil and gas CEOs say the war has flipped 2026 from an expected surplus to a deficit.
  • U.S. crude exports have hit record highs during the conflict.

The world's biggest oil and gas execs spent the past two weeks on earnings calls saying the same thing in different ways. The energy market that exists after the Iran war won't look like the one before it.

The headline number tells you why. Iran's blockade of the Strait of Hormuz has wiped out close to a billion barrels of supply. The gap grows every day the waterway stays shut.

The Shift From Talking Point To Top Priority

Energy security has been a buzzword for years. CEOs at SLB, Baker Hughes, Halliburton, and Exxon all said the same thing this earnings season: it's now a real budget line.

Halliburton CEO Jeffrey Miller said energy security is "no longer simply a talking point." Baker Hughes CEO Lorenzo Simonelli went further. He said the shock will drive structural change across the entire energy landscape.

The new playbook the CEOs described has three parts:

  • More spending on oil drilling and production.
  • Ongoing money for low-carbon options like geothermal, nuclear, and grid upgrades.
  • Built-in backup so no single chokepoint can take the whole system down.

If you want the read on how Wall Street is actually playing the energy story, Market Briefs breaks it down each weekday morning, and a free investing masterclass comes with the sign-up.

The U.S. Becomes The Default Supplier

Asian economies have been the most exposed. They depend heavily on the Middle East for crude oil and liquefied natural gas, or LNG, which is the super-cooled form of natural gas shipped on tankers.

With Hormuz closed, those buyers are scrambling.

Diamondback Energy CEO Kaes Van't Hof said U.S. crude oil has never been more important to global supply. U.S. crude exports have hit record highs during the war.

Exxon CEO Darren Woods said governments are now reassessing their entire energy security plans. The goal is to avoid the same exposure later.

The pricing picture has flipped, too. Halliburton's Miller said oil markets had been pricing in a surplus this year. Now they're pricing in a deficit.

SLB CEO Olivier Le Peuch said oil prices will stay high even after the war ends. That will pull more investment into deepwater and offshore projects in Africa, the Americas, and Asia.

Le Peuch flagged Africa as one of the most compelling long-term opportunities, given a large base of oil and gas reserves not yet built out.

What To Watch

The next test is what happens to global oil inventories - the stockpiled oil that countries and companies hold as a buffer. Simonelli said the rebuild won't just hit pre-war levels. It will overshoot them.

That has two effects on markets. Oil demand stays stronger for longer than the basic supply-and-demand math would suggest. Service companies like SLB, Baker Hughes, and Halliburton get a multi-year tailwind on drilling.

The energy security era didn't start last week. The CEOs just made it official.

Common Investing Mistakes: Why a Stock Grade Is One Tool, Not the Whole Toolkit
  • The Briefs Score shows growth, income, and wealth preservation investors how well a stock fits their goal, with a separate letter grade for each one.

  • Research works best as one input in a process you own. The grade shows how a stock stacks up. You supply the goal, the timeline, and the rules for being wrong.

  • Before you buy anything, ask one question: does this put money in my pocket, or take money out of my pocket? Then you need a plan for the money you keep.
