Daniel Yergin needed less than a minute to set the tone.
"We're looking at the biggest disruption in world oil in history. Nothing like this is on this scale has occurred before," he told more than 10,000 attendees from nearly 90 countries gathered at the George R. Brown Convention Center in Houston. It was the opening day of CERAWeek 2026 — the annual energy conference organized by S&P Global, widely described as the Davos of energy — and the agenda built over months around artificial intelligence and Big Tech no longer existed.
What replaced it was war. On February 28, the United States and Israel launched coordinated strikes against Iran. In response, Iran effectively closed the Strait of Hormuz — the chokepoint through which approximately 20% of the world's oil and liquefied natural gas (LNG) flows — and struck energy infrastructure across the Gulf, including the export complex of Qatar, the world's largest LNG exporter, which said the attacks would reduce its LNG export capacity by 17%. Brent crude surpassed $100 per barrel by March 8 — eight days after the first strikes.
Against that backdrop, the 44th edition of CERAWeek — founded that same number of years ago by Yergin himself — became the most consequential energy crisis summit since the shocks of the 1970s. What follows are the ten strategic takeaways Yergin presented in his opening address and in prior interviews with Axios, Reuters, and BOE Report.
1. "The Biggest Disruption in World Oil in History"
Yergin did not reach for euphemisms. With the Strait effectively closed, he was categorical: "We're looking at the biggest disruption in world oil in history. Nothing like this is on this scale has occurred before." The statement puts the current crisis in perspective against even the Arab oil embargo of 1973 and the Iranian Revolution of 1979 — episodes that reshaped the global energy map but never involved the physical closure of the world's most strategically critical maritime chokepoint.
2. The "Nightmare Scenario" Has Not Arrived — But Could
Yergin acknowledged that the current situation, though severe, has not yet reached his worst-case threshold. In a Financial Times op-ed published as the conflict escalated, he wrote that "the most difficult scenario would be severe damage to infrastructure and a lengthy closure of the strait." CERAWeek closes Friday, March 27 — exactly one month after the first strikes. That threshold is days away.
3. "This War Has Been Half a Century in the Making"
Yergin placed the conflict in long perspective. "This is a war that's been brewing for almost half a century, and the concerns about the Gulf have been prominent for half a century. But now it's happening," he said. He recalled that in The Prize — his definitive history of the oil industry, winner of the 1992 Pulitzer Prize for General Non-Fiction — he wrote about the obsession of presidents and prime ministers with the price of oil. That observation, he said, could be published today without changing a word.
4. The World Is More Resilient Than in 1979 — but Still Under Pressure
Yergin was careful not to fuel panic. The global energy architecture of 2026, he argued, is qualitatively different from the 1970s: "This crisis is unfolding in a world in which the global oil and gas system is more resilient and diversified than it has been in decades." Among the structural differences: the United States is now the world's largest oil producer, Saudi Arabia operates overland pipelines routing crude to Red Sea export terminals that bypass the Strait entirely, and the International Energy Agency (IEA) coordinates strategic petroleum reserves across more than 30 member countries.
5. The Words of the Year Are No Longer "Transition" or "AI" — They Are "Security" and "Affordability"
CERAWeek 2026 was built around artificial intelligence and Big Tech. The war dismantled that agenda within weeks. "Security and affordability will be the defining words for CERAWeek," Yergin said — a sharp pivot from a program that for the first time in 44 editions included a dedicated AI Hub featuring representatives from NVIDIA, Google, Microsoft, Meta, and Amazon.
6. Renewables Will Be Reframed as Energy Security, Not Climate
Yergin anticipated how the conflict is reconfiguring the political case for clean energy: "There is going to be a rebranding of renewables in terms of energy security, rather than climate." The argument will no longer center on reducing emissions — it will center on reducing dependence on unstable regions. For net energy-importing countries, the distinction is material: it shifts the supporting coalition, the regulatory framework, and the investment thesis.
7. All Producers Will View the World Differently
The conflict foreshadows a broad recalibration between producers and consumers. "All those producers will look at the world differently, and countries will look at their degree of dependence differently. I think there will be a big push for diversified supplies," Yergin said. The practical implication is concrete: greater weight for U.S. and Australian LNG in Asian markets, an acceleration of long-term contracts outside the Persian Gulf — and a strategic premium on Atlantic-basin exporters such as Argentina, whose crude and LNG export routes access the Atlantic directly, bypassing both the Strait of Hormuz and the Suez Canal.
8. The Convergence of AI and Energy Remains Structural
The conflict displaced technology from center stage — it did not retire the debate. "The race for AI is fusing the energy and technology industries like never before," Yergin said. For the first time in the conference's history, CERAWeek features a dedicated AI Hub. The war interrupted the conversation; it did not close it.
9. Exit Scenarios Must Be Built Urgently
Beyond diagnosis, Yergin identified what is missing from the conflict's management: "What the situation is crying out for now are two or three different scenarios for how all this might end." The underlying assessment is serious: there is no clear diplomatic architecture for reopening the Strait of Hormuz, and that absence, Yergin suggested, is as dangerous as the closure itself.
10. "There Has Been More Upheaval and Disruption in Markets Than Ever Before"
With more than 10,000 attendees from nearly 90 countries in Houston, Yergin closed his opening remarks with a line that functions as both verdict and forecast: "There has been more upheaval and disruption in markets than ever before." Throughout the week he will chair the conference's most consequential on-stage conversations — U.S. Energy Secretary Chris Wright addressed attendees on opening day; Sultan Al Jaber, chief executive of ADNOC, Abu Dhabi's state oil company, and U.S. Interior Secretary Doug Burgum are both scheduled for Wednesday — as the world waits to learn how much longer the Strait can remain closed.
