The Strait of Hormuz remains the world’s key energy chokepoint, and every crisis there threatens new price increases

The Strait of Hormuz remains the world’s most important energy chokepoint, and every disruption there threatens a new wave of price increases

Tensions around the Strait of Hormuz are not losing their significance even at the beginning of March 2026, because it is a narrow sea passage through which a huge share of global trade in oil and liquefied natural gas passes. Whenever news emerges of military escalation, attacks on commercial ships, or a possible blockade of the passage between Iran and Oman, markets do not read this merely as a regional security problem, but as a direct threat to the global energy supply. In such circumstances, the prices of crude oil, gas, transport, and insurance react almost automatically, and the consequences then spill over into industry, transport, heating, and household budgets far beyond the Middle East.

According to the latest estimates by the U.S. Energy Information Administration, during 2024 and in the first quarter of 2025, more than a quarter of total global seaborne oil trade and around one-fifth of global consumption of oil and petroleum products passed through the Strait of Hormuz. The same institution also states that this is the world’s largest chokepoint in oil logistics, with an estimated 23.2 million barrels per day in the first half of 2025. In other words, no other narrow maritime passage has such capacity or such an influence on the global energy market.

Why this passage is so crucial

The Strait of Hormuz is important not only because it is narrow and difficult to replace, but because it connects the Persian Gulf with the Gulf of Oman and the open sea, making it practically the main outlet for exports of crude oil, condensate, and gas from a number of key producers. The International Energy Agency warns that oil from Saudi Arabia, the United Arab Emirates, Kuwait, Qatar, Iraq, Bahrain, and Iran reaches global markets along this route. In the event of a more serious disruption, not only would immediate deliveries be endangered, but also the availability of a large share of the world’s spare production capacity, which is concentrated to the greatest extent precisely in Saudi Arabia.

That is why news about a possible closure of the strait never remains just local news. It immediately becomes a story about how fast the price of a barrel could rise, how much refineries would have to pay for crude, how much shipping and insurance costs would increase, and how much that shock would be passed on to the prices of fuel, the chemical industry, fertilizers, food, and transport. The economic effect of the Strait of Hormuz is therefore not limited to the energy sector: it is directly linked to inflation, industrial competitiveness, and economic growth.

Asia is first in the line of fire, but Europe is not spared

The International Energy Agency points out that most of the oil leaving the Strait of Hormuz ends up in Asia, above all in China, India, and Japan. The latest estimates by the U.S. Energy Information Administration show that the Asian market is also the most exposed in the liquefied natural gas segment: about 83 percent of the LNG that passed through this passage from the Persian Gulf countries in 2024 went to Asian buyers. This means that a prolonged disruption would first hit the world’s largest energy importers, their power systems, and energy-intensive industries, from petrochemicals to chip and steel production.

But Europe is not beyond the reach of such a blow. Although the European Union now imports more LNG from the United States than before and part of its pipeline gas from Norway, the European gas market remains strongly linked to the global LNG trade. Eurostat states that in the third quarter of 2025, the largest LNG suppliers to the European Union were the United States, Russia, and Algeria, while Norway was the main partner for imports of gaseous natural gas and oil. At first glance, this suggests a lower direct dependence of Europe on the Strait of Hormuz than in Asia, but market logic says otherwise: if Asian buyers are left without Qatari gas because of disruptions, they will begin buying cargoes more aggressively from other sources, including U.S. LNG. Then Europe, even without a physical interruption of its own supplies, enters into market competition that drives prices up for everyone.

That is precisely why a disruption in the Strait of Hormuz is for Europe not only a question of volumes, but also a question of price. European industry, which is still recovering from the energy shock after the Russian invasion of Ukraine, is extremely sensitive to a new period of more expensive gas and oil. Higher input costs particularly hit the chemical industry, metallurgy, cement, glass, logistics, and agriculture, and then spill over to end consumers through more expensive fuel, heating, and consumer goods.

Qatari LNG as a key element of global balance

The market’s particular sensitivity stems from the fact that Qatar is one of the world’s key LNG exporters, and almost all of its exports pass precisely through the Strait of Hormuz. The U.S. Energy Information Administration estimates that during 2024 around one-fifth of total global trade in liquefied natural gas passed through this passage, primarily from Qatar, which exported about 9.3 billion cubic feet of LNG per day through this corridor. When such exports are called into question, the consequences are felt not only in energy bills, but also throughout supply logistics, stock planning, and the operation of gas terminals.

Because of this, every escalation around Hormuz immediately turns into a rise in the risk premium. Traders do not wait for an actual and complete supply disruption, but prices already incorporate the possibility of shortages in advance. This is also visible in the latest reports from agencies and the media: the Associated Press reported in recent days that war escalation linked to Iran seriously disrupted oil and gas flows, with price increases and a strong rise in supply concerns in Asia, while the International Maritime Organization at the beginning of March issued several warnings because of attacks on commercial ships and threats to the safety of seafarers in the strait area.

The security risk is not only military, but also logistical and financial

When talking about the Strait of Hormuz, the possibility of a formal blockade is often placed in the foreground. However, markets react even before such a scenario occurs. A series of incidents, interference with navigation, electronic systems or communications, rising insurance prices, or a decision by major shipping companies to temporarily avoid the passage is enough. Then physical traffic does not need to stop completely for an economic удар to occur. It is enough for it to slow down, become more expensive, and become unpredictable.

That is precisely why the reaction of the International Maritime Organization is important for the economy, and not only for the safety of navigation. In its statements of 1 and 6 March 2026, that organization warned that attacks on civilian shipping and seafarers are unacceptable and that the safety of commercial ships must remain a priority. Such messages also carry very concrete market weight, because they confirm that the problem is no longer hypothetical. As soon as transporters assess that the passage is too risky, more expensive alternatives, longer routes, additional insurance, and a greater need for inventories are activated, all of which are ultimately built into the final price of energy and goods.

How much of an alternative does the world actually have

One of the reasons why the Strait of Hormuz is so important is the fact that alternatives exist, but they are limited. Part of Saudi Arabia’s exports can be redirected toward the Red Sea via the east-west oil pipeline, and the United Arab Emirates have the option of exporting part of their output via terminals on the coast of the Gulf of Oman. Nevertheless, the International Energy Agency and the U.S. Energy Information Administration have for years warned that these alternative routes cannot fully replace the volume that otherwise passes through Hormuz. This means that in the event of a longer and more serious disruption, part of the supply would simply disappear from the market, at least temporarily.

Because of this, strategic reserves are often mentioned in public debates. Member countries of the International Energy Agency hold mandatory stocks that can be activated in extraordinary circumstances to mitigate a short-term shock. But that mechanism is not a permanent solution either. Reserves can buy time, calm markets, and help avoid immediate panic, but they cannot for long replace the normal daily flow of tens of millions of barrels of oil and enormous quantities of LNG. If the disruption were to last, the problem would very quickly move from prices into the actual availability of energy commodities.

Inflation, production, and household budgets

History shows that energy shocks rarely remain confined within the energy sector. Research by the International Monetary Fund confirms that rising energy prices have a strong and broad effect on inflation, with the blow transmitted not only directly through fuel and heating, but also indirectly through production and transport costs. That is why every more serious crisis in the Strait of Hormuz is immediately also a macroeconomic issue. More expensive oil means more expensive diesel and gasoline, more expensive goods transport, and greater pressure on central banks. More expensive gas means higher costs for industry and households, but also additional pressure on electricity prices where gas still plays an important role in power generation.

For consumers, in practice this means a very simple thing: even if they do not live near the Persian Gulf, they may feel the consequences at gas stations, in heating bills, and in the prices of products in shops. For countries, this means a harder task in containing inflation and preserving industrial competitiveness. For central banks, it means an awkward combination of slower growth and renewed inflationary pressure. And for governments, it means greater political risk, especially where energy costs are directly linked to social standards.

The broader message for Europe and the rest of the world

The Strait of Hormuz remains the world’s key energy chokepoint precisely because geography, geopolitics, and market psychology meet there. Geography, because it is a narrow corridor that is difficult to replace. Geopolitics, because it is located in an area of permanent tensions between regional and global powers. Market psychology, because prices react even to the mere possibility of disruption, and not only to its full realization.

For Europe, the main lesson is that energy security is not measured only by the origin of current supplies, but also by resilience to global shocks. Even when Europe does not depend decisively on the physical flows passing through Hormuz, it remains deeply immersed in the global oil and LNG market, where a disruption at one end of the system raises prices at the other. For Asia, the message is even more direct: the largest energy importers there remain the first line of impact in every more serious crisis in the Persian Gulf.

That is precisely why the story of the Strait of Hormuz is not only the story of one passage between Iran and Oman. It is the story of how much the global economy is still tied to a few sensitive transport and energy chokepoints, how quickly a security incident turns into an economic problem, and how far the energy transition, despite the progress of renewable sources, is still from neutralizing the risk of fossil fuel bottlenecks. As long as such a large share of the world’s oil and gas passes through Hormuz, every new warning from that area will remain one of the most important economic stories of the day.
