Dear Readers,

Most people think of helium as the gas that fills birthday balloons, not as the invisible thread holding together the entire global chip industry. But right now, with the Strait of Hormuz effectively shut down and Qatar's helium exports crippled, that thread is unraveling fast, and the consequences reach from TSMC's fabs in Taiwan all the way to the AI model running on your phone.

In today's Deep Dive, we break down how a 24-mile-wide waterway between Iran and Oman became the single biggest risk to $800 billion in annual semiconductor production, why helium has no substitute, why Taiwan's LNG reserves cover just 11 days, and what happens when the world's most advanced technology collides with the world's oldest form of leverage: control of a chokepoint. Let's get into it.

All the best,

Kim Isenberg

“If the war has given you a sense of déjà vu from the energy crisis of the '70s, you're not alone. In fact, in some ways, it's been worse. Fatih Birol, the head of the International Energy Agency, said on Monday that the war has caused global oil production to drop by 11 million barrels per day. That's more than "the loss of 10 million barrels per day from the oil shocks in 1973 and 1979 combined," reports The New York Times.”

Four weeks ago, the world woke up to an energy crisis that hadn’t been seen since the 1970s. On February 28, 2026, the United States and Israel launched coordinated airstrikes against Iran, including the killing of Supreme Leader Ali Khamenei. Within hours, Iran’s Islamic Revolutionary Guard Corps transmitted a chilling message across maritime radio frequencies: no ship would be permitted to pass through the Strait of Hormuz. What followed was not a conventional naval blockade with warships and submarines. It was something far cheaper and, in many ways, far more effective. A handful of drone strikes near the strait’s entrance, a few attacked tankers, and suddenly the world’s insurers pulled their war-risk coverage. Shipping companies, unable to insure their vessels, stopped sailing. Within days, tanker traffic through the strait collapsed by roughly 90 percent. From a normal daily flow of about 138 vessels, the number dropped to near zero.

The immediate reaction focused on oil prices, Brent crude surged past $100 per barrel for the first time in four years and has since climbed above $107. But behind the headlines about gas station prices and geopolitical brinkmanship, a far more consequential disruption was unfolding: one that threatens the production of the very chips that power artificial intelligence, cloud computing, and the data centers on which our digital world depends. The question is no longer whether the Strait of Hormuz crisis will affect the semiconductor industry. It already has. The real question is how deep the damage will go, and whether the global AI boom can survive the shock. Let’s find out in todays Deep Dive.
