Iranian attack causes Qatar helium supply to be "halved," putting immense pressure on the semiconductor supply chain

A disruption to helium supplies triggered by shocks to Qatar’s energy infrastructure is working its way through the supply chain to the global semiconductor and medical industries.

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

Wall Street Insights noted that Qatar is one of the world’s most important helium supply countries, accounting for roughly one-third of global supply.

Iran’s attacks on the region’s energy infrastructure have thrown Qatar’s liquefied natural gas (LNG) production into a standstill, and LNG production is a key upstream link for helium extraction. Qatar National Oil and Gas Company then issued a warning, saying there is a risk of helium exports collapsing.

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 force majeure announcement marks that Qatar’s capacity shock has officially been transmitted from the upstream stage to downstream distribution, moving the supply chain disruption from a warning phase into a phase of real impact.

Pressure on both the medical and semiconductor industries

Helium is irreplaceable in both industrial and medical applications.

In the medical sector, hospitals rely on helium to keep MRI magnetic resonance imaging equipment operating normally, and it is also used to treat patients with certain respiratory system diseases.

On the manufacturing side, helium is a core inert gas in the production processes for high-end semiconductors, and it is especially indispensable for the fabrication steps of cutting-edge products such as NVIDIA AI accelerator chips.

According to a market update report released by the hospital procurement services organization Vizient, when allocating limited supplies, AirGas has already clearly placed priority for its medical institution customers above other industries.

At present, practitioners in the U.S. medical imaging field say that this helium market volatility has not yet caused substantive impacts on patient diagnosis and treatment.

However, as the supply shortfall continues to widen, the semiconductor industry’s exposure to disruption may become even more far-reaching. If foundry fabs such as TSMC face long-term limitations in helium supply, they could experience a major capacity shortfall.

If the tensions between Iran and the region persist, the time window for Qatar’s LNG production to resume will be difficult to predict. The helium supply shortfall will continue to expand, thereby imposing substantive constraints on global AI chip production capacity.

The semiconductor industry is at a critical juncture in addressing the massive demand surge driven by data center construction, and any systemic contraction in raw material supply will directly magnify existing capacity bottlenecks.
