Europe avoided the expected fuel shortage despite the disruption in the Strait of Hormuz. Emergency reserves, increased refinery output, and alternative imports from the United States, Canada, India, Nigeria, and other suppliers helped compensate for a large portion of the lost supplies from the Gulf. According to Oil Price, the crisis revealed the resilience of global energy markets, as refineries, traders, governments, and consumers quickly adjusted production, trade routes, inventories, and demand in response to the crisis.

Early warnings about the Strait of Hormuz pointed to the possibility of European airports and fuel markets facing an actual shortage by the start of summer. However, this shortage largely did not materialize, revealing the ability of global energy markets to adapt and their tendency to price in worst-case scenarios long before they occur.

Additionally, alternative producers directed their shipments toward the most profitable markets. Europe imported additional fuel from the United States, Canada, Nigeria, India, and South Korea. Saudi Arabia increased its shipments from the port of Yanbu on the Red Sea, allowing it to bypass the Strait of Hormuz entirely. By early June, reports indicated that Saudi jet fuel flows to Europe via the Red Sea were higher than before the closure of the strait.

When the Strait of Hormuz was effectively closed at the end of February, initial forecasts were grim. The disruption affected a shipping route that had carried nearly 20 million barrels per day of crude oil and its derivatives before the conflict, while Gulf exporters also supplied the world with a large share of diesel, jet fuel, and LPG. Europe appeared particularly vulnerable because it imports far more jet fuel than it produces and relies heavily on supplies from the Middle East.

By April, warnings of an actual shortage became more specific. The International Energy Agency estimated that Europe could begin facing a jet fuel shortage in June if it could only compensate for half of the supplies it usually imports from the Gulf. Airlines warned of possible flight cancellations, airports studied emergency measures, and European officials began discussing the coordinated release and redistribution of jet fuel reserves. Ryanair indicated that losing between 10% and 20% of available supplies could force airlines to reduce their capacity during the summer season.

However, June has now passed, and European aviation did not come to a halt. There was no acute shortage at fuel stations, no diesel rationing, and no widespread physical shortage that dominated initial discussions. Prices rose sharply, inventories fell, and some routes became less economically viable, but the energy system absorbed a disruption that the International Energy Agency described as the largest in the history of the global oil market.

This outcome deserves more attention because it reveals something important about how energy crises are discussed. Markets are exceptionally good at identifying vulnerabilities, but they often treat exposure to a crisis as if it were an inevitable collapse.

In the worst shock of the Strait of Hormuz flow disruption, oil supplies were disrupted by about 14 million barrels per day, equivalent to approximately 14% of global demand. Middle Eastern exports of refined products largely disappeared, many refineries and gas processing facilities were shut down, and producers cut output because they could not export or had no storage space.

Jet fuel appeared to be one of Europe's main vulnerabilities. The continent consumes about 1.6 million barrels per day of jet fuel and kerosene, while its production is only 1.1 million barrels per day, leaving a large structural need for imports. Before the conflict, most of these imports came from the Middle East. By April, shipments loaded in the region had almost completely stopped, while inventories at key trading hubs fell to historically low levels.

Theoretically, this conclusion seemed inevitable. Existing inventories would be drained, alternative shipments would be insufficient, and an actual shortage would appear around June. But energy balances are not static. Assuming that a lost barrel will remain lost permanently ignores the most important feature of internationally traded commodity markets: when scarcity drives up prices, producers, refiners, traders, and consumers all begin to change their behavior.

Europe did not avoid the shortage because the disruption was less severe than expected, but because the rest of the system responded more effectively than many initial forecasts assumed. The most notable response came from emergency reserves. In March, the 32 member countries of the International Energy Agency agreed to release 400 million barrels of emergency oil stocks, the largest coordinated release in the organization's history. This did not compensate for every barrel lost from the Gulf of Mexico, but it bought time for commercial supply chains to adapt and reassured refineries that additional feedstock would remain available.

Then refineries changed what they produced; European plants increased the proportion of each barrel converted into jet fuel, pushing regional jet fuel production to record highs. U.S. refineries made a similar adjustment, with American jet fuel output exceeding 2 million barrels per day on a four-week average for the first time. U.S. exports later reached record levels as European and Asian prices attracted supplies across the Atlantic.

These adjustments were neither free nor efficient. Shipments traveled longer distances, refineries sacrificed production of other fuels, traders paid higher shipping costs, and airlines faced much more expensive contracts. Yet the actual product arrived. Initial forecasts had treated Europe's reliance on Middle Eastern jet fuel as a fixed relationship.

Supply received most of the attention, but changes in demand were also important. High fuel costs made some air routes economically unviable, leading airlines to cut unprofitable services. Flights through and around the Middle East were canceled or rerouted, reducing fuel consumption in the regions most affected by the disruption.

This reduction was not enough to close the supply gap on its own, but commodity markets do not require a single radical intervention. They rebalance through hundreds of small changes: a refinery increases jet fuel output, another delays maintenance, an airline cancels an unprofitable route, a trader reroutes an oil tanker, a government releases its stocks.

The process is complex and costly, but these adjustments collectively transform an apparent physical shortage into a price shock. This distinction is often overlooked during the early phase of an energy crisis. Analysts calculate current inventories, subtract expected demand, and determine the date when stocks are expected to reach a critical level. The resulting deadline attracts headlines because it suggests a countdown.
