Beyond Oil: How a Strait of Hormuz Crisis Could Disrupt Urea, Helium, and Semiconductors

📰 In-Depth Economic News

Why Would a Closure of the Strait of Hormuz Shake Even Urea and Helium? 🌍
A Simple Guide to Supply Chain Shocks Beyond Crude Oil and LNG

War and a sea lane blockade do not just push up oil prices.

This article explains step by step how the effects can spread through urea into logistics and agriculture, and through helium into semiconductors.

When people hear that war in the Middle East is escalating or that the Strait of Hormuz could be blocked, most immediately think of crude oil and LNG prices. That is indeed the most direct shock. But the global economy does not run on oil and gas alone.

Some energy shocks spread into unexpected products. Two representative examples are urea and helium. Urea is a key ingredient in fertilizer and diesel exhaust fluid, so it affects agriculture and logistics, while helium is an essential gas in semiconductor manufacturing, so it affects advanced industry.

In other words, if a blockade or war drags on, the shock can spread sideways through chains like crude oil and LNG → urea → logistics and fertilizer, and LNG → helium → semiconductors. This article aims to explain those linkages in a way that even first-time readers can easily understand.

1. Let’s Start with the Big Picture: Why Does the Story of Oil Extend to Urea and Helium? 🧭

The core point is simple. Energy does not move by itself.

• Coal and natural gas are not only fuels for generating electricity, but also feedstocks for chemical products.
• That means when energy supply is disrupted, it is not only power plants that are affected, but also fertilizer, urea, and industrial gases.
• As a result, entirely different industries such as logistics, agriculture, and semiconductors can all be affected.

Many people stop at the idea that “if war breaks out, fuel prices go up.” But in the real economy, what comes next is often even more important. When raw materials become unstable, factories stop. And when factories stop, logistics, food supply, and semiconductors are all affected.

💡 The Core Structure of This Article

Energy shocks do not end with higher fuel prices.
Coal and gas shortages → urea shortages → logistics and fertilizer problems
LNG production disruptions → helium shortages → semiconductor problems
Understanding these chains of connection is what really matters.

2. Why Is Urea Important? Because It Is Not Just Another Chemical Product 🚚

Urea is not something people notice often in daily life, but it is an extremely important substance. It is used heavily in two main areas.

• Fertilizer : essential for agricultural production.
• Diesel exhaust fluid : necessary for reducing emissions from diesel trucks and commercial vehicles.

Diesel exhaust fluid is especially important for trucks. Passenger diesel vehicles use relatively small amounts, but freight trucks and dump trucks consume much more. In many vehicles, if diesel exhaust fluid runs out, performance is restricted or the engine may even stop. That means a shortage of urea can quickly turn into a logistics problem.

So even though urea may look like a minor chemical product, in reality it is a core material that affects both logistics and agriculture at the same time.

3. Why Is Urea Linked to Coal? 🔥

There are several ways to produce urea, but one of the cheapest and most widely used methods is to extract ammonia from coal and then produce urea from it. That is why disruptions in coal supply can also affect urea production.

The important point here is that coal is not just fuel for power plants. It also serves as a feedstock for the chemical industry. If coal becomes scarce, the problem is not limited to electricity generation. The supply of industrial materials such as urea can also decline.

4. How Did the 2021 Diesel Exhaust Fluid Crisis Begin? 📉

The 2021 diesel exhaust fluid crisis is often remembered simply as “something caused by China blocking exports.” That is not entirely wrong, but the full sequence becomes much clearer when we look at what happened beforehand.

After the pandemic, relations between Australia and China deteriorated sharply, and China imposed strong restrictions not only on Australian wine, beef, timber, and lobster, but also on coal. Coal was the real issue.

Wine and lobster can be replaced with products from other countries, but with coal, quality differences matter a great deal. China believed it could simply replace Australian coal with more coal from Indonesia and Mongolia, but in reality power generation efficiency fell. Australian coal had a high calorific value, which made it advantageous for power plant operations.

Then severe flooding in Shanxi Province made things worse. Coal mines were flooded, domestic Chinese production was disrupted, and power and heating pressure rose as winter approached. In the end, China moved to secure energy and industrial feedstocks first, and as a result, controls on urea exports began.

📘 The 2021 Diesel Exhaust Fluid Crisis in One Line

Diplomatic conflict → disruption of Australian coal → lower generation efficiency + flooding → fear of coal shortages → urea export controls → diesel exhaust fluid shortage crisis
In other words, the diesel exhaust fluid crisis was, in essence, a supply chain shock that began with energy and coal.

5. Why Could This Time Be More Complicated? 🌐

In 2021, the central issue was that one major supplier, China, became constrained. This time, however, the structure could be different. That is because multiple producing countries could be disrupted at the same time.

Egypt has produced urea using natural gas imported from Israel, so if that gas supply is cut off, urea plants may have to shut down. Iran also faces the risk of plant disruptions due to war and airstrikes. Russia has long faced export limitations because of war and sanctions, and China could again move to slow or control exports.

If that happens, the issue does not stop at “prices go up.” The more important question becomes whether enough physical supply can actually be secured. Urea affects both fertilizer and logistics, so if supply shrinks, global agricultural costs and transport costs can rise together.

6. The Next Problem Is Helium: Why Are LNG and Helium Connected? 🎈

Helium is easy to think of as just the gas used in balloons, but in reality it is a very important industrial gas for semiconductors and advanced manufacturing.

Helium exists in very small amounts inside natural gas. In the process of liquefying natural gas into LNG, methane becomes liquid, but helium remains gaseous until the end. That difference makes it possible to separate helium out.

That is why countries that process large amounts of natural gas, especially major LNG exporters, can naturally become important players in helium supply as well. A representative example is Qatar.

In other words, disruptions in LNG production can also lead to disruptions in helium supply. That is why helium is often mentioned together with energy news.

7. Why Is Helium So Important for Semiconductors? 💻

In semiconductor production, helium is used to cool wafers, create highly controlled gas environments, and keep various pieces of equipment operating stably. In many cases, it is not easy to replace with another gas, so if supply becomes tight, factory operations can become very sensitive and unstable.

Semiconductor plants are extremely expensive to stop. That is why the price of helium matters, but what matters even more is whether the required amount can be secured when it is needed.

8. The Rare Gas Supply Chain Has Already Been Shaken Once Before 🧪

Helium is not the only example. During the war in Ukraine, supplies of other rare gases such as neon, krypton, and xenon were also severely disrupted.

In particular, the Azovstal steel plant in Mariupol was not just an ordinary steel mill, but an important hub in the rare gas supply chain. When facilities like that were destroyed, the semiconductor industry came under serious pressure in securing raw gases.

Since then, many companies have diversified their supply chains, so for neon, krypton, and xenon, some alternatives have been built up. But helium is still much more tightly tied to the structure of natural gas and LNG production, which means it remains a material with meaningful supply risk.

9. The United States Could Be an Alternative, but It May Not Be a Perfect Answer 🇺🇸

When helium supply is disrupted, many people think, “Then why not just switch to U.S. supply?” In fact, the United States is an important helium producer. But reality is not quite that simple.

Helium is not abundant in every gas field. In older conventional natural gas fields, helium may accumulate in larger amounts, but shale gas fields often have relatively low helium concentrations. So even if natural gas production increases, helium production may not rise at the same pace.

Also, even though the United States has large production, it also has large domestic demand. So it would be wrong to look only at total production and conclude that replacing supply would be easy. What matters is whether there is actually enough exportable volume available.

📗 The Lesson We Should Take from This

For any raw material, it is not enough to look only at production volume.
To truly understand a supply chain, you also have to look at exportable volume, transport routes, and refining and separation facilities.

10. In the End, What Should the World Be Watching? 📝

The most important lesson from today’s global supply chain is this: an energy crisis is no longer just about oil prices.

If coal and gas are disrupted, urea can become scarce. If urea becomes scarce, trucks can stop running and fertilizer prices can rise. If LNG production is disrupted, helium supply can shrink. If helium becomes scarce, semiconductor plants and advanced manufacturers can come under pressure.

In other words, the longer war or a sea lane blockade continues, the more people need to watch not only crude oil and LNG at the surface, but also the chemical feedstocks and industrial gases hidden behind them. Urea and helium are representative examples that show exactly why.

📌 Key Takeaways

• Energy shocks do not stop with crude oil and LNG, but can spread to urea and helium.
• Urea is the raw material for fertilizer and diesel exhaust fluid, so it affects both agriculture and logistics.
• Helium is linked to LNG production and is an essential industrial gas in semiconductor processes.
• The 2021 diesel exhaust fluid crisis was a supply chain shock that began with energy and coal problems.
• The longer war and sea lane blockades continue, the more important question becomes not price, but whether the necessary physical volume can actually be secured.
