The global semiconductor supply chain is facing a critical vulnerability as the blockade of the Strait of Hormuz chokes off roughly one-third of the world's helium, a gas essential for manufacturing advanced chips.
The ongoing blockade of the Strait of Hormuz has halted nearly one-third of the world's helium supply, triggering warnings of rising costs and production risks for major chipmakers including TSMC, Samsung, and SK Hynix that depend on the critical gas.
"The concept of the blue highway is going away," Salvatore R. Mercogliano, a former naval officer and associate professor of history at Campbell University, told the Wall Street Journal. "We won’t see a return to the normalcy we had prior to this no matter what."
Qatar Energy, which produces about a third of the world’s commercial helium from its Ras Laffan complex, suspended operations in early March after an attack by Iranian forces. The disruption has stranded about 200 helium containers, each valued at about $1 million, according to AP News. The chokepoint also threatens the supply of other key materials like high-purity sulfuric acid and naphtha, a petroleum byproduct used by Japanese photoresist makers like Shin-Etsu Chemical.
The shortage directly threatens the semiconductor manufacturing that underpins the entire digital economy, from AI data centers to consumer electronics. While major firms like TSMC report having several months of inventory, the sustained pressure could inflate costs across a supply chain already grappling with geopolitical tension, ultimately affecting prices for everything from cars to new AI infrastructure investments.
A Crisis Beyond Energy Prices
While initial attention focused on oil prices, the second-order effects are proving more alarming. Helium is irreplaceable in chip manufacturing for cooling, circuit printing, and creating the stable, inert environment needed for wafer production. South Korean memory chip giants Samsung and SK Hynix are particularly exposed, sourcing about 65 percent of their helium from Qatar.
The crisis extends beyond helium. Chip manufacturing is an energy-intensive industry, and both South Korea and Taiwan are heavily dependent on energy imports that transit the strait. Taiwan, home to TSMC, imports nearly 40 percent of its liquefied natural gas (LNG) from the Middle East, while South Korea relies on the route for about 70 percent of its crude oil and a fifth of its LNG. "I first worry about Taiwan's power," TSMC CEO C.C. Wei said earlier this year, highlighting the electricity needed to run advanced EUV lithography machines.
Downstream Pain and Investor Jitters
The ripple effects are already being felt. Nintendo has announced a price hike for its new Switch 2 console, while automotive manufacturer Isuzu Motors and bathroom maker Toto have been forced to adjust production due to shortages of naphtha.
In response, chipmakers are scrambling to diversify their supply chains. TSMC, Samsung, and SK Hynix are reportedly paying a premium to secure helium from the United States and Canada and are accelerating efforts to recycle the gas. "We have secured helium and other raw materials from various regions before the conflict," TSMC CFO Wendell Huang said in April, though he admitted that prices for some chemicals could rise.
For investors, the blockade introduces a new layer of geopolitical risk into the semiconductor sector. The situation highlights the fragility of a highly concentrated supply chain and could slow the momentum of the AI boom if data center construction is impacted. As NYU professor Scott Galloway noted, the world may be sliding toward "gangsterism," where pay-to-pass shipping lanes become the norm, fundamentally altering the rules of global trade.
