The biggest energy shock of our lifetimes, and almost no one is pricing it

For the first time in recorded history, all four material pillars of modern civilisation are disrupted simultaneously. The S&P 500 is two percent from all-time highs.

In early 2020 I was living in Hawaii with my three-month-old daughter during COVID. It was, strangely, bliss. The tourists had gone, the roads were quiet, and for the most part the shelves were fully stocked. Then one week a rumour spread about formula. Panic set in overnight and by morning the shelves had been cleared out. For nearly eight hours I could not find formula of any brand, anywhere on the island. I was freaking out in Safeway while my daughter was hungry at home and I had nothing to give her. When a local family eventually handed me a tin from their own cupboard, the relief was the kind that stays with you.

That was one product, on one island, for one morning. It was a rounding error compared to what is happening right now.

Energy shocks are notoriously badly modelled. We reach for historical analogies (1973, 1990, 2022) and in doing so we miss what is categorically different about this one. Every prior shock was a single commodity event: one input, disrupted, eventually resolved. What has unfolded in the Gulf since March 2026 is something else entirely. For the first time in recorded history, all four material foundations of the modern world have been simultaneously disrupted from a single geographic chokepoint.

"We tend to underestimate the complexity of our own civilisation." Vaclav Smil, How the World Really Works

Vaclav Smil spent decades documenting the physical foundations of a civilisation that had, for fifty years, every reason to ignore him. The post-Bretton Woods order was so effective at delivering cheap, reliable inputs that an entire generation of supply chain thinking was built on a single premise: abundance is the default. You do not build resilience into a system that has never failed you. You optimise for efficiency and pocket the difference. His point is not that fossil fuels are good. It is that ammonia, steel, cement, and plastics are what the world is actually made of, and all four of them require energy inputs so large and so specific that replacing them is measured in generations, not election cycles. We have built extraordinary complexity on top of these four pillars and forgotten, almost entirely, that the pillars exist. In the second half of 2026, billions of people will learn what those pillars are and what happens when they fail.

Pillar one: Ammonia
This is the food equivalent of a demographic cliff. You can see it coming. Almost no one is looking.

Urea prices are up 43%. Gulf fertiliser plants are offline. China has extended its export ban through August 2026. The ammonia supply that underpins nitrogen fertiliser, which in turn underpins roughly half of all calories consumed on earth, has been severed from one of its primary production corridors at the precise moment the Northern Hemisphere spring planting window opens. The cruelty of agricultural supply chains is their lag. Farmers who cannot source fertiliser this April will not produce a visible shortage this summer. The shortage arrives next winter, quietly, in prices. By the time it is legible to markets it will be too late to reverse. The denial here is not malicious. It is structural. The signal is real and the pain is delayed.

Pillar two: Steel
280 bulk carriers stranded and the construction industry hasn't noticed yet.

Iran and Bahrain between them account for around 18% of global iron ore pellet exports, the primary input for electric arc furnace steelmaking. The BAPCO refinery in Bahrain, struck by Iranian missiles on 31 March, took the entire country's refining capacity offline in a single evening, with the Alba aluminium smelter drawing power from the same complex. 280 bulk carriers are stranded in Gulf waters with no clear timeline for when they move again.

Pillar three: Plastics
85% of Middle Eastern polyethylene exports, offline.

Saudi Arabia, the UAE, and Qatar together supply the majority of the world's seaborne polyethylene, the resin that becomes packaging, pipes, medical supplies, agricultural film, and automotive components. That supply is not delayed or redirected. It is offline. The converters — the factories that turn resin into finished product — are quietly scrambling for US Gulf Coast and Korean alternatives at a moment when every other buyer on earth is making the same call. Margins will compress, lead times will blow out, and the products downstream will reprice. Most consumers will not know why.

Pillar four: Sulfur
Cascading effects. The ingredients that actually power the world just went offline.

Gulf sour crude refining produces the world's sulfur as a byproduct, and approximately 44 to 45% of globally traded sulfur flows from this single process in this single region. Sulfur is not a niche chemical. It is the feedstock for sulfuric acid, which is required for fertiliser production, copper leaching, and semiconductor etching. It connects every other pillar on this list. Disrupt sulfur and you tighten the fertiliser situation further, slow critical minerals extraction, and add another constraint to the chip supply chain already under pressure from helium shortages at Ras Laffan. It is the multiplier in a crisis that already has too many of them, and it is receiving almost no coverage.

"There is no quick substitution for the four pillars. The timescales of energy transitions are not quarters. They are generations." Vaclav Smil

Smil's most important observation is also his most uncomfortable: there is no fast substitute for any of this. The question is not when the alternatives arrive. The question is what breaks in the interim and whether the people responsible for managing those breaks are paying attention.

The S&P 500 is two percent from all-time highs.

Markets are not irrational. They are optimised to price what they can model, and they have no template for this. A single-commodity shock has historical analogues, discount rates, and recovery curves. A simultaneous four-pillar disruption at the world's primary energy chokepoint does not. The denial is not greed. It is the rational response of a system encountering something genuinely outside its frame of reference.

Cable Capital operates in the gap between what markets are pricing and what supply chains are experiencing. Deep expertise across three continents, direct supply and demand relationships, and no interest in waiting for the situation to resolve itself.

It won't. Not this season.
