Iranian attack cuts Qatar's helium supply "in half," putting "enormous pressure" on the semiconductor supply chain

```

The disruption of helium supply caused by the impact on Qatar's energy infrastructure is being transmitted through the industry chain to the global semiconductor and medical industries.

According to a Bloomberg report this week, on March 17, AirGas, one of the largest packaged gas distributors in the United States, officially announced that due to a force majeure event, it expects to reduce the monthly helium supply to some customers to 50% of normal levels with an additional surcharge of $13.50 per 100 cubic feet.

Wallstreetcn noted that Qatar is one of the world's most important helium suppliers, accounting for about one-third of global supply.

Attacks by Iran on the region's energy infrastructure have led to a halt in Qatar's liquefied natural gas (LNG) production, and LNG production is a critical upstream link for helium extraction. Qatar's national oil and gas company immediately issued a warning, stating that helium exports are facing the risk of collapse.

AirGas is a subsidiary of the French Air Liquide Group (Air Liquide SA) and is one of the largest packaged gas distributors in the United States. This announcement of force majeure marks that the impact on Qatar’s capacity has officially extended from upstream to downstream distribution, and the supply chain interruption has moved from a warning phase to a stage of substantive impact.

Medical and semiconductor industries both under pressure

Helium is irreplaceable in both industrial and medical fields.

In the medical field, hospitals rely on helium to keep MRI magnetic resonance imaging equipment running properly, and it is also used to treat certain respiratory disease patients.

On the manufacturing side, helium is a core inert gas in high-end semiconductor production processes, and is especially indispensable in the manufacturing of advanced products such as Nvidia's AI accelerator chips.

According to a market update report released by hospital procurement service agency Vizient, AirGas has explicitly prioritized medical customers over other industries when allocating limited supplies.

Currently, practitioners in the U.S. medical imaging field have said that the current helium market fluctuations have not yet had a substantive impact on patient care.

However, as the supply gap continues to widen, the semiconductor industry may be hit harder. If foundries like TSMC face long-term helium supply constraints, significant capacity shortages may arise.

If tensions between Iran and the region persist, the timeline for resuming Qatar's LNG production will be difficult to estimate, and the helium supply gap will continue to expand, thereby placing substantial constraints on global AI chip production capacity.

The semiconductor industry is at a critical juncture in meeting the massive demand brought by the data center construction boom; any systemic contraction in raw material supply will directly amplify existing capacity bottlenecks.
