Why the Tungsten Shortage Is a Severance, Not a Squeeze

A commodity squeeze rations the raw material. A severance cuts the chain at its narrowest point and leaves the raw material stranded. Tungsten in 2025 and 2026 is the clearest live example of the second kind, and the distinction changes what an investor should expect next.

The ore is not the problem. The step that turns ore into something usable is.

What is the difference between a squeeze and a severance?

In a squeeze, supply of the underlying material tightens. Prices rise, marginal production restarts, substitution begins at the edges, and the market clears. It is uncomfortable and it is self-correcting.

In a severance, someone removes a step in the middle of the chain. The material still exists. Buyers still have money. But the processing capacity that converts one into the other sits somewhere they cannot reach.

Prices in a severance do not behave like prices in a squeeze. They do not pull supply forward, because the constraint is not mine capacity. They pull capital toward building the missing step, which takes years, and in the meantime the market splits into people who are inside the wall and people who are outside it.

Why is tungsten the example?

Because the chokepoint is unusually visible.

Tungsten moves through the world as ammonium paratungstate, known as APT. That is the traded intermediate. Concentrate is converted into APT, and APT becomes powder, and powder becomes the carbide that cuts and drills almost everything industry makes. Roughly two thirds of tungsten ends up as cemented carbide.

Almost all APT conversion capacity sits in China. So does about 79 percent of mine output, roughly 67,000 of the world's 85,000 tons in 2025, according to the US Geological Survey.

The two facts are not equally important. A buyer who finds non-Chinese ore has solved the smaller problem. They still have very few places to convert it.

What actually happened?

A sequence, not a single event.

In late 2024 the United States raised tariffs to 50 percent on several Chinese tungsten products under Section 301 of the Trade Act of 1974. In December 2024 China announced restrictions on dual-use goods. In February 2025 it introduced export controls covering tungsten and four other strategic metals.

China had already been tightening independently. Mining quotas set by the Ministry of Natural Resources fell from 63,000 tons in 2023 to 62,000 in 2024, alongside stricter environmental inspection across the producing districts of Jiangxi, Hunan and Fujian.

The prices repriced through 2025. Rotterdam quotations for 65 percent concentrate rose from $266 to $551 per metric ton unit. APT rose from $331 to $675. Roughly a doubling across the chain, and notably, the intermediate moved at least as hard as the ore. That is the signature of a mid-chain constraint rather than an ore shortage.

Is this a geological shortage?

No, and conflating the two leads to bad conclusions.

Tungsten resources are geographically widespread. China holds the largest reserves, around 2.5 million tons, but its share of global reserves is roughly half, well below its four fifths share of production. Other countries have the rock.

What they lack is the will and the time. Grades in tungsten ore usually run below 1.5 percent tungsten trioxide, so nearly everything removed from a tungsten mine is waste. That makes deposits capital-hungry and slow, which is why cheap Chinese output was allowed to close mines elsewhere without much argument.

The processing industry followed the mining out. Rebuilding the mine is hard. Rebuilding the chemistry plant is harder, and it is the one that matters.

Why does demand make this worse?

Because the fastest-growing slice of demand destroys the metal.

Most tungsten consumption tracks industrial machining, which is broad, slow-moving and difficult to kill. Tools wear out and get replaced. A meaningful share of Western supply comes back as scrap, which is recycled into powder.

Defense demand does not come back. A kinetic penetrator is consumed on use. As rearmament programmes across the United States, Europe and Asia expand, they add a strand of demand that is price-insensitive and irreversible, at the same moment that governments are also building strategic stockpiles.

Inelastic demand meeting a severed chain is a different problem from inelastic demand meeting a tight mine.

What does the policy response tell you?

That governments have stopped treating this as a market they can buy from.

In September 2026 the US Department of War announced a binding agreement of about $450 million with a domestic tungsten manufacturer and an Australian partner, covering manufacturing capacity and stockpiles, including the restart of a Nevada mine and its APT plant.

Three details matter more than the headline. A Defense Logistics Agency stockpile contract attached to it runs to as much as $2 billion, several times the investment. The government took redeemable preferred equity plus warrants for up to 19.9 percent of the manufacturer, with the right to name a director. And the mine is scheduled to restart in late 2027, with the processing plant following in the second half of 2028.

Announced in 2026. Metal in 2028. That gap is the most useful number in the story.

What is the precedent?

Rare earths in 2010 and 2011, when China restricted exports and Western prices spiked before new capacity and substitution eventually eased the constraint. The current episode is the same play executed with more precision, because it targets the conversion step rather than the ore.

Gallium, germanium and graphite have all seen versions of the same approach since 2023. Tungsten is not an isolated case. It is the clearest current illustration of a method.

What should an investor take from this?

Three tests, which travel to any material.

Where is the narrowest point in the chain, and who owns it? For tungsten it is APT conversion, not mining. For uranium it is conversion and enrichment. For rare earths it is separation.

Does substitution fail on a physical property or on cost? Cost-based substitution solves shortages. Physics-based substitution does not, and tungsten fails on density and melting point together.

How long is the physical response? If the answer is measured in years, the shortage outlasts the news cycle that revealed it, and the repricing is structural rather than a spike.

None of this argues for a position in tungsten, which is thinly traded and awkward to access. It argues for recognising a category of event that is becoming more common, and for understanding which businesses sit on the safe side of it. That is the subject of the companion article on where value sits in a critical mineral shock.

FAQ

What caused the tungsten shortage? Policy rather than geology. China, which produces about 79 percent of world tungsten, introduced export controls in February 2025 following US tariff action in late 2024, and had already been cutting mining quotas.

What is APT in the tungsten market? Ammonium paratungstate, the chemical intermediate that most tungsten trade actually moves. Concentrate is converted to APT before it becomes powder and then carbide. Almost all conversion capacity is in China.

How much did tungsten prices rise? Rotterdam quotations for 65 percent concentrate rose from $266 to $551 per metric ton unit across 2025, and APT from $331 to $675.

Is there enough tungsten in the ground? Yes. Resources are geographically widespread and China's share of reserves, around half, is well below its share of production. The constraint is processing capacity, not geology.

Why can tungsten not be substituted? Because it combines the highest melting point of any metal with a density near that of gold, and as carbide a hardness approaching diamond. Alternatives lose on one property or another.

How long before new Western supply arrives? The Nevada restart announced in September 2026 targets late 2027 for the mine and the second half of 2028 for the processing plant, subject to due diligence and definitive agreements.
