The global energy crisis is not over; it is evolving. A confluence of signals, from ongoing disruptions at the Strait of Hormuz to refinery shutdowns in the Middle East and critically low inventories in the United States, indicates that supply risks are intensifying. Ultimately, the market may be forced to rebalance through a contraction in demand, which could drag down the global economy.

Reports of a merchant vessel fire near the coast of Oman surfaced late last Sunday, with the cause yet to be confirmed. Iran's Revolutionary Guards claimed that two oil tankers, allegedly encouraged by the U.S., exploded and lost propulsion after navigating a dangerous southern channel of the strait. Details regarding the vessels' names, flags, crew, and casualties were not disclosed, and the incident could not be independently verified.

The Revolutionary Guards issued a stark warning: as long as the U.S. continues its military provocations in the Middle East, the entire waterway will be unsafe for navigation. "The Strait will not permit the transport of petrochemical cargoes; not even a drop of oil or gas will pass through normally," the statement declared.

Shipping data from LSEG reveals a sharp drop in traffic, with only four vessels transiting the Strait of Hormuz last Sunday, compared to eight the previous day. Since last Friday, at least three product tankers and one very large crude carrier (VLCC) have entered the strait to load crude. The risk of a major shipping route disruption pushed Brent crude futures above $90 per barrel on Monday.

Previous market optimism, fueled by crude prices retreating from a wartime peak of $118 per barrel to around $85, suggested the energy crisis was abating. However, the refined products supply chain is now flashing multiple warning signs. Consumers ultimately use gasoline and diesel, not crude oil, making a shortage of these refined fuels the core emerging risk.

Data from the International Energy Agency (IEA) shows that global refinery throughput in the second quarter of this year was down by 5 million barrels per day compared to the same period last year, averaging just 78 million barrels per day, due to disruptions from conflicts in both the Middle East and Russia.

A temporary U.S.-Iran ceasefire in mid-2026 briefly eased supply pressures. Data from Kpler showed Gulf crude exports averaging 4 million barrels per day that month, but product exports were only 1 million barrels per day—just a quarter of pre-conflict levels. With the strait facing renewed disruptions, expectations for a recovery in refinery capacity in Asia and the Middle East have been dashed.

Major refining facilities across multiple Middle Eastern nations are experiencing widespread shutdowns. Key refineries in Saudi Arabia, Bahrain, Kuwait, and the United Arab Emirates are either operating at reduced capacity or are completely idled. To offset the sharp decline in crude imports, overall refinery utilization in Asia has also contracted.

Furthermore, sustained Ukrainian drone strikes have severely damaged Russia's refining industry, causing domestic fuel shortages that have forced Moscow to restrict diesel exports to curb local prices.

The U.S. Capacity Buffer is Depleted, with Refining Margins Hitting Record Highs

In the first half of the year, the United States leveraged its massive refining capacity to absorb global shortfalls, exporting large volumes of crude, gasoline, diesel, and jet fuel. However, this buffering capacity is now nearing its limit.

Since the conflict began, total U.S. commercial crude inventories and strategic petroleum reserves have fallen to their lowest levels since 1984. Gasoline stocks are at seasonal lows not seen since 2012, while diesel inventories have only slightly recovered from two-decade lows.

As the U.S. enters the peak summer driving season, with refineries prioritizing domestic supply, the nation's weekly exports of oil and petroleum products have dropped to 10.7 million barrels per day—the lowest since March and down from an April peak of 14.2 million barrels per day. America's ability to help stabilize global oil prices is weakening.

The refining crack spread is a direct indicator of fuel scarcity. The U.S. benchmark 3-2-1 crack margin recently approached $70 per barrel, setting a new record. Refining margins in Northwest Europe have also risen to seasonal highs near $30 per barrel. European diesel cracks have surpassed $65 per barrel, while U.S. gasoline crack spreads are nearing the highs seen during the 2022 Russia-Ukraine energy shock. These exceptionally high refining premiums signal a severe shortage of end-user fuels.

As the conflict enters its fifth month, initial market hopes for U.S. presidential action to curb soaring domestic fuel prices have faded. The multitude of negative signals from the refining sector suggests very limited room for such intervention.

Global refinery capacity will be difficult to restore in the short term. Returning Middle Eastern facilities to full operation and repairing Russia's damaged refining capacity will take months, if not years. The risk of further Ukrainian attacks on Russian refineries remains ever-present.

The energy market barely managed to absorb the shocks from geopolitical turmoil in the first half of 2026. Now, with global fuel inventories continuing to decline and various stockpiles being drawn down, the market's only path to rebalancing supply and demand may be through a contraction in consumption, which would inevitably weigh on global economic activity.
