Hitchhiker Commodities: The Supply Chains Nobody Owns

Key Takeaways:

• Byproduct commodities like helium, sulphur, bromine and naphtha have no supply chains of their own and vanish the moment someone stops drilling or refining for something else.
• Unlike oil, none of these critical materials have strategic stockpiles — when supply stops, there is nothing to buy time while the world adjusts.
• The near term picture is more resilient than the headlines suggest, but the impulse to diversify is already visible.

The Strait of Hormuz crisis has been treated primarily as an oil story. Brent surged past $125 a barrel. Headlines tracked tanker movements. Governments debated strategic petroleum reserves.

That framing misses the bigger picture.

Beneath the oil headlines, something else is breaking. There is a category of materials that underpins modern life but has no supply chain of its own. These materials do not have their own markets, their own price benchmarks, or their own logistics networks. They exist only because someone, somewhere, decided to process natural gas or refine crude oil, and they happened to come along for the ride. They are byproducts. Hitchhikers. Their availability is not determined by their own supply and demand. It is determined by production decisions made for an entirely different commodity. When the host process runs, they appear. When it stops, they vanish. And right now, across multiple industries, the host processes have all stopped at once.

The Commodities Hidden Inside Modern Life

Most people have never thought about industrial gases. But they are everywhere. Helium cools MRI magnets to near absolute zero. Hydrogen powers the light sources inside the most advanced chip making machines. Oxygen is blown through molten iron at over 1,700°C to make steel. Nitrogen blankets semiconductor clean rooms to prevent contamination at the atomic scale. Neon fires the lasers that etch transistors onto silicon. These gases reach their customers through dedicated pipelines built into factory floors on contracts running 15 to 30 years, as cryogenic liquids in vacuum insulated tanker trucks, or compressed into high pressure cylinders for thousands of smaller users. The infrastructure is vast, invisible, and almost none of the gases that flow through it have a supply chain designed to survive a disruption.

Helium is separated from natural gas during LNG processing. Nobody drills for it. Nobody mines it. It is the only element on the periodic table that, once released, leaves Earth permanently. It cools every MRI scanner, every advanced chip factory, every rocket fuel system. Qatar produced roughly a third of global supply before Iranian strikes forced the Ras Laffan complex offline. Two of fourteen LNG trains suffered damage that may require 3 to 5 years to repair. Spot prices surged. Hundreds of cryogenic containers were reportedly stranded near the Strait, and because liquefied helium evaporates continuously in transport, much of that inventory may already be unrecoverable.

Sulphur is recovered from oil refining and gas sweetening. It is the feedstock for sulphuric acid, without which you cannot produce phosphate fertilizers, leach copper from ore, or extract nickel for battery cathodes. Nearly half of all seaborne sulphur trade transits the Strait. The Middle East supplied 63% of Asia's sulphur imports in 2025. The Kuwait benchmark hit $765 a tonne, the highest since its launch. China banned sulphuric acid exports. Russia extended its own sulphur export ban. There is no strategic reserve. Anywhere. And sulphur's disappearance does not stop at sulphur. It cascades. Less sulphur means less sulphuric acid. Less sulphuric acid means less phosphate fertilizer. Less fertilizer means lower crop yields. Lower crop yields mean higher food prices. The first link breaks and every subsequent link feels it with a lag, and by the time the damage is visible, the planting window has closed.

Bromine, 75% of which comes from the Dead Sea, sits inside the flame retardants in virtually every circuit board, cable, and electronic casing manufactured anywhere in the world. It is also used in the plasma etching that carves fine features onto advanced semiconductors. Like helium and sulphur, it is not produced for its own sake. It is extracted from brine as part of potash and mineral processing. Its supply is determined by someone else's production economics.

Naphtha is a byproduct of crude oil refining. It is the primary feedstock for the petrochemical crackers that produce polyethylene, polypropylene, and the plastics that run through virtually every manufacturing supply chain on earth. Asia depends on the Middle East for over 55% of its naphtha imports. When the Strait closed, that feedstock stopped arriving. Petrochemical plants in South Korea and Indonesia declared emergency shutdowns within days, cutting operating rates by a quarter to a third. Roughly $26 billion of petrochemical and plastics trade from the region is exposed, around 9% of global flows.

Same structural flaw in every case. Byproduct economics. Geographic concentration. No independent supply chain. No strategic reserves.

Where Is the Safety Net?

The hitchhiker commodities are handled by some of the largest industrial companies in the world. Refineries recover sulphur. ICL and Albemarle produce bromine. Dow, LyondellBasell, and Westlake run petrochemical crackers. What none of them have built is a buffer. There is no strategic reserve for sulphur. No stockpile mechanism for bromine. No naphtha inventory beyond what sits in tankers and port storage. The only hitchhiker commodity where anyone has built even a partial safety net is helium, and that infrastructure sits with three companies: Linde, Air Liquide, and Air Products. They manage the global distribution of helium, hydrogen, nitrogen, and dozens of specialty gases across chemicals, manufacturing, healthcare, and electronics. More than half their revenue is locked into long term onsite contracts. They have built underground salt cavern storage in Texas, Germany, and the United States that can hold helium indefinitely at scale, and those caverns were well stocked heading into the crisis because Russian supply had actually been loosening the market through 2025. As chips get smaller, the gases required to make them become more exotic and more critical: extreme purity levels, a single advanced chip making machine consuming roughly 10,000 litres of hydrogen per hour, a single contamination event in a memory chip production line causing losses over $20 million in a month. For these companies, a helium price spike is a margin event, not a crisis. A 10% increase in helium prices translates to earnings boosts of roughly 0.7% for Linde, 1.1% for Air Liquide, and 2.3% for Air Products. They benefit from scarcity. Industrial gas pricing has risen 40 to 50% since 2019, consistently outpacing inflation, because gases represent a small but critical share of customer costs and no management team will risk a production shutdown over a gas bill. They also benefit from the reshoring and factory construction that follow every disruption. For every other hitchhiker commodity, the ride has stopped and there is no safety net to catch the fall.

What the Market Sees, and What It Doesn't

The near term picture is more resilient than the headlines suggest. Semiconductor fabs hold roughly six months of helium inventory and recycle at 75 to 90% efficiency. TSMC, Samsung, SK Hynix, Intel, and Infineon have all indicated no production disruption. The United States is the world's largest helium producer. The industrial gas majors' caverns provide a buffer. Anyone who tells you the chip industry is about to shut down because of helium is overstating the case.

But resilience in one sector does not mean resilience everywhere. Sulphur feeds sulphuric acid, which feeds fertilizer, which feeds crops, which feeds people. Helium shortages hit hospitals before they hit chipmakers, because MRI departments cannot outbid semiconductor fabs. Global manufacturing activity had just begun signaling a recovery before the shock hit. After 2022, manufacturing indicators in developed markets fell sharply and four years later had still not recovered.

Beneath the resilience and the cascading risk sits something more structural. There are no strategic reserves for any of these commodities. The US helium reserve was sold off in the 1990s. No country stockpiles sulphur. Strait transit volumes have dropped roughly 95%. The entire architecture was designed around one assumption, and on February 28 that assumption broke.

What to Watch

The impulse to diversify is already visible. But diversification that replaces reliance on the Middle East with reliance on Russia for helium or China for renewables does not solve the structural problem. It relocates it. After the oil shocks of the 1970s, global demand growth went from 8% a year to marginal declines within a decade. The question is whether this crisis will trigger a similar rethinking, not just of where these materials come from, but of whether an economy built on byproducts can continue to treat their supply as someone else's problem.

The hitchhiker commodities have always been there. They have always ridden on someone else's infrastructure, invisible until the moment the ride stops. That moment is now.
