War in Iran Cuts Global Helium Supply, Hits Chip Production

The war in Iran has disrupted Qatar’s LNG operations, removing a third of global helium supply and constraining semiconductor production. For Mexico, this elevates supply chain risks in electronics, automotive, and nearshoring-driven manufacturing, increasing input costs and dependency on US suppliers, while exposing limited domestic capacity to secure critical industrial gases.

The war in Iran has forced a cessation of liquefied natural gas operations in Qatar, effectively removing one-third of the global helium supply from the market. This disruption creates an immediate bottleneck for semiconductor manufacturers that rely on the gas for critical cooling and atmospheric control.

The critical nature of helium in high-technology manufacturing stems from its unique physical properties, for which there are no technically or economically viable substitutes in modern integrated circuit fabrication. 

"Helium is expensive relative to other gases, so, for the most part, where there are substitutes for helium, helium is no longer used," says Phil Kornbluth, President, Kornbluth Helium Consulting.

Helium is necessary to maintain ultra-clean and ultra-cold manufacturing environments. Without a consistent supply of ultra-high-purity helium, advanced production lines face inevitable slowdowns or complete operational halts. The gas is essential for heat transfer, energy dissipation, and the stabilization of vacuum chambers during the lithography and etching processes.

Industrial helium is not primarily captured from the atmosphere due to its low concentration; rather, it is recovered as a byproduct of natural gas processing, specifically during the production of liquefied natural gas, or LNG. The economic viability of helium is inextricably linked to the profitability and operational status of LNG infrastructure. Consequently, any disruption to the energy sector in major gas-exporting regions directly impacts the global availability of helium.

According to the Mineral Commodity Summaries 2026 report published by the US Geological Survey (USGS), the total recoverable helium reserves worldwide are estimated at 31.3 billion cubic meters. The geographic distribution of these reserves and the production figures from 2025 highlight a significant concentration of geopolitical risk.

The suspension of operations by QatarEnergy following regional hostilities and the closure of the Strait of Hormuz by Iran have neutralized the export capacity of Qatar, the holder of the largest individual helium deposit in the world. Given that Qatar accounted for more than one-third of the global supply in 2025, the sudden removal of this source represents an unprecedented supply shock. This shortage is exacerbated by the fact that Russian supply is already restricted by international trade sanctions, leaving the United States and Algeria as the only remaining large-scale producers capable of servicing international markets.

Technical Requirements and Industry Projections

Semiconductor manufacturing requires helium of extreme purity to support thermodynamic functions and environmental stabilization. During plasma etching and chemical vapor deposition (CVD), helium serves as a carrier gas and a back-side cooling agent for silicon wafers. Its high thermal conductivity and chemical inertness allow for rapid heat dissipation without reacting with sensitive substrates. 

In 2025, global semiconductor sales reached US$791 billion, representing an annual increase of 25.6%, according to data from the Semiconductor Industry Association (SIA). This growth, largely driven by investments in AI infrastructure, cloud computing, and automotive electrification, has placed sustained upward pressure on helium demand. The SIA warned in January 2023 that a sudden supply shock could significantly impact manufacturing operations throughout the world.

Logistics and Storage Infrastructure Limitations

The logistics of helium management are complex due to its boiling point of 4.2 K, or −268.9 °C. Most helium is transported as a cryogenic liquid in specialized ISO containers, which experience daily boil-off rates. Long-term storage is restricted by the limited global infrastructure. According to Deutsche Welle, only four major underground storage facilities are now operational:

• Beaumont, Texas: A facility owned by Linde that was expanded in 2025.

• Cliffside, Texas: Managed by the Bureau of Land Management, or BLM, as part of the Federal Helium Reserve.

• Gronau-Epe, Germany: Used primarily to stabilize the EU market.

• The US Mid-Continent: Various smaller private facilities in Kansas and Oklahoma.

Most liquid helium storage sites only possess the capacity to hold between three and seven days of production. Therefore, the obstruction of maritime routes in the Persian Gulf prevents the rotation of inventory and leads to the saturation of storage at the source, which forces Qatari facilities to cease production entirely.

Market Outlook and Risk Mitigation

The stability of the global supply chain depends on the duration of the conflict in Iran and the potential for alternative transit routes for Qatari LNG. However, replacing established suppliers is a difficult process because helium procurement is typically governed by long-term, multi-year contracts. While untapped deposits exist in regions such as Canada and South Africa, the development of the necessary extraction and liquefaction infrastructure requires lead times exceeding 18 months.

The semiconductor industry has already implemented efficiency measures to reduce helium consumption per wafer, yet large-scale recycling systems at the fab level remain in early stages of adoption. Experts suggest that the most effective method to reduce supply vulnerability is for manufacturers to purchase helium from suppliers with diverse geographic sources. 

In a scenario of prolonged scarcity, it is anticipated that suppliers will prioritize shipments to high-margin sectors, such as processors for AI and data centers, which could displace manufacturers of lower-margin consumer electronics.

As the conflict continues, the industry must prepare for a period of high price volatility and potential rationing of high-purity gases.
