The Loss of Helium Exports Due to the Iran Crisis Will Prove Critical

Helium is a colourless, odourless, non-flammable, non-renewable inert gas. It is commercially extracted from natural gas using fractional distillation*. As the second lightest and second most abundant element in the universe, helium has widespread applications across multiple industries and medical fields. The sudden disruption to helium exports via the Strait of Hormuz is now having a significant negative impact on the medical sector, semiconductor manufacturing, and several other critical industries.

*Fractional distillation is a laboratory and industrial process used to separate mixtures of liquids with different boiling points. In the case of helium, it involves a cryogenic process in which natural gas is cooled to extremely low temperatures. This takes advantage of helium’s exceptionally low boiling point (−268.9°C), allowing it to be separated from nitrogen, methane, and other components.

Roughly two-thirds of the world’s helium supply comes from the United States, with much of the remainder supplied by Qatar. With the Strait of Hormuz currently closed, supply lines have effectively been choked. This disruption is now threatening the production and operation of semiconductor-based technologies used in everything from automobiles and washing machines to smartphones, space systems, and artificial intelligence infrastructure. Helium plays a vital role in semiconductor fabrication, particularly in cooling extreme ultraviolet lithography machines used to print microchips.

At present, around 200 helium containers remain stranded in the Persian Gulf, each holding approximately 41,000 litres of liquid helium. Experts warn that the gas will gradually boil off within 35 to 48 days, rendering the shipments unusable. These containers were destined for South Korea and Taiwan, which together manufacture approximately 90% of the world’s most advanced semiconductors. Without chips, global supply chains face severe disruption. Some analysts have even highlighted the knock-on effect on defence systems, noting that modern AI-driven technologies rely heavily on semiconductor availability.

In the medical sector, the shortage of helium is already affecting hospitals and diagnostic centres worldwide. MRI (magnetic resonance imaging) machines rely on helium to cool superconducting magnets to extremely low temperatures. Current shortages are delaying refills, increasing operational costs, and threatening the continuity of MRI services. Beyond MRI systems, helium is also critical for NMR spectrometers, cryosurgery procedures, and respiratory treatments.

• NMR spectrometers are used to determine molecular structures essential for research and pharmaceutical development.
• Cryosurgery and cryoablation use helium’s ultra-low temperatures to freeze and destroy diseased tissue.
• Respiratory medicine uses helium-oxygen mixtures (heliox) to treat severe airway obstructions.

Donald Trump has issued an ultimatum stating that the United States will withdraw from the war zone “with or without a peace deal” once Iran’s nuclear capabilities are neutralised. However, logistics experts caution that even after hostilities cease, it could take more than three months for helium supply chains to normalise. If there is significant structural damage to Qatari production facilities, shortages could persist for years.

White House officials have indicated that US military forces could begin returning home within three weeks. However, recent history suggests that such timelines are often optimistic and subject to change.

Without semiconductors, modern economies could grind to a halt. Chips underpin almost every aspect of daily life, from aviation and automotive systems to global shipping, communications, and digital infrastructure. In emerging markets, access to MRI technology is already becoming limited, and prolonged disruption could soon affect developed nations as well.

Beyond the geopolitical narrative, the helium shortage represents a critical vulnerability in global supply chains. If the conflict continues, the consequences of helium scarcity may prove more damaging than the geopolitical tensions that caused it.
