GLOBAL DIGITAL ECONOMY

Intro: The Iran War has led to shortage of helium, vital for AI but also for many of Britain’s smaller businesses. If the Strait of Hormuz blockade continues, a chip shortage could well be on the cards

The world has lost 40pc of its helium supply since the start of the latest war in the Gulf, first from Qatar and then from Russia.

We will soon find out whether the global digital economy can shrug off losses of such a critical gas on this scale and whether our political leaders will allow the AI boom to keep gobbling up an ever-greater share.

Industry cannot make advanced AI chips or semiconductors below 10 nanometres without ultra-high purity helium to cool the wafers and stabilise the plasma for etching. Even workhorse chips for cars and computers require lower-grade helium at 99.999pc purity.

But we also need helium for other high priorities: in nuclear power, advanced weaponry, aerospace, fibre-optic cables, quantum computing, chromatography, or to cool superconducting magnets in MRI machines. There are no easy substitutes. Liquid helium is the coldest known substance on Earth, with a boiling point of -269°C. Hence, why everybody is scrambling around trying to scoop up whatever they can find in the world.

It cannot be synthesised artificially – it comes from the radioactive decay of thorium and uranium – and is hard to store. China has strategic stockpiles of everything but not for this one vital input.

Helium is a small cost for digital behemoths with the deepest pockets, relying on “fabs” or foundries that cost $20bn (£15bn) a shot. Wafer fabs are not going to close, so with supply shortages, the larger conglomerates will be prepared to pay more than anybody else.

Another insidious process is at work. The semiconductor industry is in effect hoarding its scarce supply for the most lucrative AI fabs while rationing helium for routine “mature-node” chips that play a far bigger role in the day-to-day economy.

Triaging has taken hold. The industry reserves what they have for AI accelerators, high-bandwidth memory, and advanced logic chips for data centres.

There is less left for chips in cars, laptops, and the consumer electronics that we all rely on. Everybody is talking about petrol prices but nobody is talking about helium.

The fear is that there could be a repeat of the chip shortage that shut down European car factories during the pandemic. A Covid lockdown at a plant in Malaysia caused crippling losses on the other side of the globe. If a semiconductor factory anywhere in the world says that it won’t be able to supply more chips, then implicitly, the car industry is going to have big problems in the third and fourth quarters.

Qatar normally supplies a third of the world’s helium, a by-product of natural gas production at its giant North Field. Not a single shipment has moved through the Strait of Hormuz since the war began.

Some 200 cryogenic containers are stranded in the Persian Gulf and are slowly heating up, causing gas to leak out through the pressure valves to avert a lethal explosion.

Vladimir Putin has compounded the shortage by imposing what amounts to a ban on helium exports outside the Eurasian Economic Union, purportedly to secure supply for Russia’s domestic economy and fibre-optic industry. This endangers another 9pc until the end of 2027.

For once, it is China that is taking the immediate brunt of the supply chain shock. It produces barely 15pc of its own helium needs. All the rest comes from Qatar and Russia.

America is sitting pretty in one sense. It is the world’s biggest helium producer with two-fifths of the market.

But that does not shield the US from the larger supply-chain consequences any more than US oil supremacy spares it from rising crude prices and mounting shortages of jet fuel and diesel, leaving aside fertilisers, sulphur, and aluminium.

The US subcontracts most of its chip production to Asia. Its share of global semiconductor output has collapsed to 10pc from 37pc in the 1990s. It will be years before the US chips act and manufacturing rearmament turn this around.

More than 75pc of the world’s semiconductors are made in the Far East. Nvidia either makes or finishes all of its most advanced Blackwell chips at TSMC plants in Taiwan, while Samsung makes high-bandwidth AI chips for Google in South Korea. Both countries normally rely on Qatar for two-thirds of their helium.

Large volumes of workhorse chips for just about everything else are made in Vietnam, Malaysia and Thailand, often at arms-length operations for China.

Analysts say the world had plenty of helium before the war broke out and can probably cover half the loss from Qatar at a pinch.

The industry has an informal system for allocating scarce supply to the most critical needs. The top of the food chain are MRI machines, chip manufacturing, aerospace, and nuclear power. At the bottom end are things like welding. There is no doubt that some people are going to get badly hurt.

One thing we should have learnt from Covid is that once the world’s just-in-time (J-I-T) supply chain goes into convulsions, with ships scattered to the four winds and stuck in the wrong place, the effects can be drastic, long-lasting, and out of all proportion to the nominal value of the goods.

If the war drags on for a few more weeks – as it may do so since both Donald Trump and Iran’s Revolutionary Guards think they are winning – there are only two solutions. Either the market destroys demand in its own ruthless way or governments step in with emergency measures and make hard choices, something that Britain seems incapable of under Sir Keir Starmer.

For aviation fuel, diesel, or naphtha, it may mean a taste of wartime rationing. For helium, it may soon be a question of whether liberal democracies allow billionaire tech giants to outbid everybody and hoard scarce gas for unpopular AI expansion.

Do politicians finally face down the hyper-scalers and redirect helium supplies to the urgent priorities of military and energy rearmament, as well as to sustain routine sectors that employ infinitely more people?

Just days ago, Marco Rubio, the US secretary of state, more or less, admitted that Iran’s regime now has enormous power to do harm and that Washington has no coherent plan to restore the status quo ante, let alone to reach a better outcome that vindicates the war. “The Strait of Hormuz is basically an economic nuclear weapon that they’re trying to use against the world,” he said.

But what is to be done about it?
