Helium

Helium is the strangest entry in this book, because it is the one commodity that is genuinely non-renewable on a human timescale in a physical sense rather than an economic one. It is produced underground by the radioactive decay of uranium and thorium over hundreds of millions of years, accumulates in a small number of natural gas fields, and is so light that once released into the atmosphere it drifts to the top and escapes into space. Every balloon that pops is helium permanently off the planet. Nothing else traded here behaves that way: a barrel of oil burned becomes carbon dioxide that stays in the system, and a tonne of copper is recyclable forever.

It is also, like sulphur, an involuntary byproduct. Nobody drills a well for helium. It occurs at fractions of a percent in certain gas streams and is stripped out during cryogenic processing, which means helium has no supply curve of its own: output is set by how much natural gas somebody else decided to produce, and by whether their plant happens to have a helium unit bolted on. A high helium price does not summon new helium. It can only, over years, justify adding recovery capacity to gas projects that were going ahead anyway.

The uses are unglamorous and almost entirely non-substitutable, which is why shortages bite so hard. The largest is cryogenics, above all cooling the superconducting magnets in MRI scanners, because helium is the only element that stays liquid down to absolute zero. The second is semiconductor and fibre-optic manufacturing, where it is used as an inert purge and coolant, which makes it a quiet input to the entire electronics supply chain. Then come welding shields, leak detection, rocket tank pressurisation, and, far down the list and first to be rationed, party balloons.

Supply is concentrated to a degree that would be alarming in any other market. The United States, Qatar, Algeria, and Russia account for the overwhelming majority, with Qatar alone around a third and its output attached to the North Field gas complex at Ras Laffan. That is the geographic problem: Qatari helium leaves through the Strait of Hormuz, so a chokepoint crisis is a helium crisis. The 2026 closure demonstrated it, taking roughly a third of world supply out and triggering the fourth named helium shortage this century.

There is no futures contract and no public price. Helium is sold under private long-term contracts negotiated bilaterally between a handful of producers and a handful of industrial gas majors, and the numbers are not published. Reported US levels held around 95,000 to 98,000 dollars a tonne through 2026, but that figure is an estimate assembled from private deals rather than a settlement anyone can trade against. The reasons no contract has formed are the familiar ones on this site, stacked: a byproduct with inelastic supply, a tiny number of counterparties, a product that is expensive and lossy to store and ship, and grades and delivery terms that differ from contract to contract.

The result is a market that is repeatedly described as critical and is priced as though it were private. When the reserve that used to absorb shocks has been sold, the supply is a byproduct nobody controls, and a third of it sails through a contested strait, the absence of a price signal stops being a curiosity and becomes the problem.
