The closure of the Strait of Hormuz revealed significant risks for the energy and materials industry. Learn how companies can prepare for future disruptions and adapt their strategies.
...the risk it revealed won't -
Nobody in the room expected the conference to open like this.
WPC 2026 was already carrying weight before it started, three years into one of the longest chemical downturns on record, order books just beginning to recover, a fragile sense that maybe the worst was behind us. Then, weeks before we gathered, the Strait of Hormuz closed. And everything changed.What happened next was the biggest supply disruption in the history of the energy industry. Not a contender. Not close. The biggest. Somewhere between 12 and 13 percent of global ethylene capacity went offline in days. Twenty percent of global methanol capacity. Nearly six million barrels a day of refining capacity going idle in the Gulf. The S&P Global team put it plainly: 15 million barrels a day removed from a 100-million-barrel-a-day market.
What the Disruption Actually Revealed
As severe as it is, the supply shock itself isn't the most important thing that happened.
The most important thing is this: Iran now knows it can close the Strait of Hormuz.
That has never happened before. Not in 1973. Not during the Iran-Iraq War. Not through any of the crises of the last 50 years. The Strait was always a theoretical vulnerabilit, a chokepoint that planners worried about and insurers priced around the edges. Now it's a demonstrated capability. A proven weapon.
And that changes the risk calculus permanently.
Not just for this cycle, or this conflict, or this administration. Permanently. Any state actor with influence in the Gulf now knows the playbook. Any government negotiating with the West now knows the card exists. Any investor building a capital model that routes a significant share of feedstock through a single maritime chokepoint is now pricing in a risk that used to be theoretical and is now empirical.
This is the shift that most post-crisis analysis is missing. The conversation keeps centering on when the Strait reopens, how quickly supply chains rebalance, whether chemicals recover by Q3 or Q4. Those are important questions. But they're the wrong first question.
The first question is: what does your investment look like if this happens again in three years?
Actioning the Insight
The companies I respect most right now are the ones asking exactly that, not as a thought experiment, but as a planning discipline.
First, stress-test your feedstock footprint. Map the percentage of your input costs that flow through the Gulf, through Qatar LNG, through any single chokepoint. If you don't know that number with confidence, you don't actually know your risk profile.
Second, put a real value on feedstock flexibility. Dow's ability to crack ethane, propane, butane, or naphtha on the same asset isn't just operational elegance, it's a hedge against exactly this kind of disruption. If your assets are locked to a single feedstock, the question isn't whether that's expensive to change. It's whether the alternative is more expensive.
Third, rebuild your capital allocation models with geopolitical stress scenarios as standard inputs, not footnotes. Not black swans. Standard scenarios. The Strait closing was always imaginable. Now it's historical. That's a different category.
None of this is about panic or pessimism. The Strait will reopen. Supply chains will rebalance. The industry will recover. But the executives who come out of this cycle in the strongest position won't be the ones who waited for normalcy to return. They'll be the ones who updated their definition of normal.
The Strait is a waterway. The risk it just revealed is permanent.
Until next week,
