Iran’s closure of the Strait of Hormuz on February 28 has held roughly a fifth of global LNG supply off the market for 11 weeks. The piece chip supply chains have been slow to wire in is that Qatar also produces about a third of the world’s helium as a byproduct of LNG processing. The fallout is now reaching foundry allocation letters, advanced packaging lead times, and 2026 memory pricing.
Reuters reported extensive damage when Iranian missiles hit Qatar’s Ras Laffan complex on March 18, three weeks into the war, and QatarEnergy declared force majeure on LNG deliveries the next day. A subsequent Reuters report put the permanent damage at 17% of Qatar’s LNG export capacity for an estimated three to five years. The wider blockade matters more in the immediate term because Qatar has no alternative LNG export route. The first Qatari cargo to clear the strait since the closure, the Al Kharaitiyat, transited on May 9 under a Trump-brokered Iran-Pakistan arrangement. The rest of the fleet is still backed up.
Qatar recovers roughly a third of the world’s helium as a byproduct of those same LNG trains, and helium can’t be substituted at scale in advanced lithography, cooling, or leak detection. When the gas flow stopped in late February, the helium stopped with it.
Reuters reported on March 31 that South Korean chipmakers had enough helium inventory to last until at least June, with Samsung and SK Hynix holding roughly four to six months of supply.
The exposure runs deeper than helium. Taiwan imports almost all of its energy, and S&P Global reported that the island’s natural gas inventory covers only 10 to 11 days of demand. Qatar supplied 27.9% of Taiwan’s LNG in 2023 according to government data cited by S&P Global, and Reuters later reported that Taiwan had relied on Qatar for roughly a third of its LNG before the Iran conflict. TSMC is a major industrial load on a thin island grid, with some estimates putting its electricity consumption near 10% of Taiwan’s total. EUV machines can’t tolerate even fractional voltage drops without ruining wafers.
South Korea sits in the same trap with a different lock. Reuters reported that it buys around 70% of its oil and 20% of its LNG from the Middle East, with most of the crude passing through Hormuz. Seoul has moved to cushion consumers and companies from the shock, including a $17.3 billion supplementary budget and efforts to secure alternative crude routes. The basic exposure remains. AI memory is being manufactured in an energy-importing economy whose fuel supply runs through a disrupted Gulf system.
Pricing Power Is Hiding A Supply Crisis
The earnings reports should give any technology executive pause. TSMC reported first-quarter 2026 revenue of NT$1.134 trillion, up 35.1% year over year. Samsung’s first-quarter operating profit rose more than eightfold to KRW 57.2 trillion. SK Hynix shares have risen more than 200% in 2026 on record AI memory results. The numbers are spectacular. They’re also misleading. Pricing power on AI accelerators is absorbing every cost shock coming out of the Gulf. Foundries are passing helium premiums, electricity hikes, and cryogenic logistics costs through to fabless designers, who pass them to hyperscalers, who pass them to anyone renting a GPU hour. Markets are absorbing the bill for now. The supply chain damage runs deeper.
The bottleneck most analysts missed sits around the silicon, not in it. TSMC’s CoWoS advanced packaging was sold out through mid-2026 before the Ras Laffan strike. Substrates are tight into 2027. Liquid helium has to travel in cryogenic ISO containers that boil off after 35 to 48 days, and industry reporting said roughly 200 of those containers were stranded near the Strait of Hormuz. Vessels rerouting around the Cape of Good Hope add 3,500 nautical miles and lose helium volume to evaporation on the way.
The chemistry layer compounds the squeeze. Gasworld reported that around two-thirds of global bromine production, used for semiconductor-grade hydrogen bromide in wafer etching, comes from Israel and Jordan. Sulfur sits upstream of copper, and copper sits upstream of every transformer, busbar, and high-voltage cable in a new data center campus. Reuters reported that Microsoft, Amazon, Alphabet, and Meta planned around $635 billion of 2026 spending on data centers, chips, and other AI infrastructure, citing S&P Global. They’re building that compute on a physical bill of materials whose delivery routes run through a contested waterway.
The contrarian read says none of this matters. Foundries are recycling helium aggressively. Inventory is holding. Margin impact at less-exposed players has been modest. That view is correct about the next two quarters and wrong about the next two years. Recycling reduces draw. It doesn’t replace the molecule. The contrarian case rests on inventory, agility, and pricing power, all of which are time-limited variables in a war whose end date no one can underwrite.
Nvidia CEO Jensen Huang reportedly joined President Trump’s May 2026 China trip at short notice. The Washington Post reported that Trump sought Chinese support on the Iran war during the Beijing visit. That’s the tell. The CEO of the most valuable company in the world is doing energy diplomacy because his supply chain runs through it.
Why Micron And Intel Are Suddenly Strategic
The implication for site selection is direct. Geopolitical risk now belongs in the data center pro forma alongside power availability, water rights, and tax abatements. Micron and Intel, drawing helium from U.S. sources and operating fabs on the North American grid, are structurally insulated in a way that hasn’t mattered for a decade and now matters very much. Expect that premium to show up in capex pricing, in offtake terms, and eventually in where the next gigawatt of training compute gets built.
The bottleneck for advanced AI is no longer algorithmic. It’s molecular and maritime. Iran has told the International Maritime Organization (IMO) that non-hostile vessels can still transit Hormuz with coordination, but Reuters reported that the war has all but halted shipments of about a fifth of the world’s oil and LNG through the strait. Executives treating the chip shortage as a supplier-management problem are managing a symptom. The disease is in the Gulf.
