Helium shortages aren't driven by panic or sudden spikes in demand; they come from a harder truth. Every tank that gets used drains a resource that can't be replaced, recovered at scale, or recreated.
The global supply depends on a narrow set of gas fields, a handful of processing facilities, and a chain of decisions that rarely prioritize helium itself. When any part of that system shifts, supply quickly tightens, and there's no reserve ready to refill what's already been lost.
The war with Iran is also affecting helium supply.
The U.S. Geological Survey estimates that before the war Qatar produced more than one-third of the world’s helium supply. Lately, however, operations at QatarEnergy’s Ras Laffan Industrial City — the world’s largest liquefied natural gas export facility, which produces helium as a byproduct — were halted after it was struck by an Iranian drone early in the war. On Wednesday, Iranian missiles crippled the plant.
A global helium shortage would ripple across a range of industries.
“Qatar makes some 30% of the world’s helium — a key input for semiconductors, industrial manufacturing, and medical imaging — while several key ingredients for fertilizer production also move through the Strait,” according to a report early this week by the chief investment office of UBS Global Wealth Management. “Any lengthy disruption will not only impact energy prices, but also food prices and industrial production.”
Most materials can be reused, recycled, or replaced. Helium doesn't offer that option; it forms deep underground over millions of years through radioactive decay, then becomes trapped alongside natural gas deposits.
Energy companies don't drill exclusively for helium; they extract it as a secondary product when the concentration is high enough to justify the cost.

That dependency creates the first point of instability: when natural gas production shifts or declines in certain regions, helium supply follows. No separate pipeline exists that guarantees steady output. The supply chain begins with decisions that have nothing to do with helium itself.
Permanence is the second pressure point. Once helium is released, it rises through the atmosphere and escapes into space. It doesn't replenish usable reserves, and it doesn't regenerate. Each release becomes a one-way exit, meaning every use carries a long-term cost, even when the immediate supply looks stable.
That reality shapes how shortages appear; the problem isn't that helium suddenly disappears, it's that it leaves the system gradually while, at the same time, demand continues growing.
Demand isn't driven by novelty or convenience; it's anchored in industries that require precision and reliability.
Medical imaging relies on helium to cool the superconducting magnets in MRI machines. Those magnets work at temperatures near absolute zero. There's no other element that provides the same combination of stability, inert behavior, and cooling efficiency at scale. Hospitals can install recovery systems to capture some helium, but they need a steady supply to operate.
Semiconductor manufacturing relies on helium to control temperature and maintain ultra-clean environments during chip production.
South Korea and Taiwan, the world’s two largest semiconductor makers, are particularly vulnerable to Middle East helium supply.
In 2025, South Korean manufacturers bought 55% of their helium from countries in the Gulf Cooperation Council, a union of six Arab nations. Taiwan bought 69% of its helium from the GCC in 2024, according to a report out Wednesday from analysts at Barclays.
The Strait of Hormuz’s effective closure has spiked helium prices by limiting supply. Bank of America estimated in a note last week that spot helium prices have surged as much as 40%, depending on the market. On Monday, Phil Kornbluth, president of Kornbluth Helium Consulting, told CNBC that prices were up by 70% to 100%, in some cases within a little more than a week.
The process tolerates very little variation, where even small disruptions affect yield and performance. As global demand for chips increases, so does the need for helium.
Aerospace and defense systems use helium to pressurize fuel tanks, purge systems, and maintain controlled environments in sensitive equipment. Those uses require reliability over long periods, which further tightens supply during disruptions.
Meanwhile, the supply side remains concentrated.
Only a handful of regions account for most global production, including the United States, Qatar, and Algeria. When those facilities shut down for maintenance, political tension, or technical difficulties, the effects ripple outward. The system doesn't have much slack; a single disruption can tighten availability across multiple industries simultaneously.
That's where the cycle of shortages comes from.
As AI platform revenues continue to scale at an accelerating pace, the downstream demand for advanced semiconductors rises in tandem.
The supply side of that equation, however, now faces a structural constraint that few macro-level investment frameworks have explicitly modelled.
“What we are observing in the helium market is a textbook example of what I call a silent bottleneck – a supply constraint that is structurally embedded in critical production processes but receives almost no attention in conventional equity analysis,” said Osric Langevin, a quantitative market analyst.
“The market is currently pricing AI infrastructure on the basis of demand-side growth, driven by the strong revenue momentum now visible across leading AI platforms.”
“What appears underweighted is the upstream fragility. When a small number of regions control the majority of supply for a gas that cannot be economically substituted in precision semiconductor manufacturing, that represents a concentration risk with direct implications for chip availability, hardware lead times, and the broader earnings trajectory of the AI sector.”
Supply expands when new facilities come online or when production ramps up in existing regions; prices stabilize, and availability improves. Then something shifts: a plant goes offline, transport slows, or demand surges. The balance tips again, bringing back shortages.
Wash. Rinse. Repeat. The pattern repeats because the system never builds enough cushion to absorb shocks.
Efforts to stabilize supply are underway. New reserves have been identified in countries such as Tanzania, and private companies continue to develop additional extraction projects.
These discoveries help extend supply, but they don't change the underlying limits. Each new source still feeds into the same cycle of extraction and loss.
Recycling has improved, especially in medical and research settings. Modern MRI systems capture and reuse a portion of helium that would otherwise be lost, while labs have adopted similar systems. These steps reduce waste, but they don't eliminate the need for a fresh supply.
Closing the Strait could take about 27% of the world’s helium offline, and any shortage will have lagged effects, Phil Kornbluth, president of Kornbluth Helium Consulting said.
“Spot prices comprise a very small slice of helium sales because it’s mostly a long-term contract business. So even though it makes for good headlines, it doesn’t have that much impact on the marketplace,” said the consultant, who’s been in the business for more than 40 years. “Contract prices have not really moved yet.”
That may change soon, however, should a prolonged shortage pressure suppliers to declare force majeure on their contract customers.
Perhaps the only saving grace is that the helium market had been “in oversupply for the last two years going into this shortage,” Kornbluth said. Still, it would probably take at least five weeks to restart production after any ceasefire.
Past oversupply acts as insurance to cushion against the current shortage. As a result, the likely deficit in supply today is probably closer to 15%, than 30%, Kornbluth said.
Alternatives exist in limited roles, but none provide a full replacement. Hydrogen can be a substitute for helium in some lifting applications, but its flammability restricts broader use. Argon and nitrogen can replace helium in certain industrial processes, but they don't match helium's performance in high-precision cooling or inert environments.
Engineers continue to refine systems using less helium, but critical applications still depend on its unique properties.
That leaves us with a clear conclusion: helium shortages don't reflect a single failure; instead, they reflect a system built on a finite resource, dependent on another industry for extraction, and the inability to recover what it uses. The cycle continues because the structure behind it hasn't changed.
That gas itself remains invisible to us in daily life, but the effects of its scarcity aren't.
