The Rerouting Is Real Now

According to Reuters, Northeast Asian refiners — primarily in South Korea and Japan — have shipped the first jet fuel cargoes to Europe since the Iran war disrupted Persian Gulf supply routes. The aviation fuel supply chain has physically rewired itself around the Strait of Hormuz.

The route adds weeks to delivery times and significant cost per barrel. Europe wasn't built to run on East Asian jet fuel at scale, but the economics now force the arrangement despite its inefficiency.

China Loosens the Tap — Slightly

China is set to allow a slight increase in refined fuel exports for June, according to Reuters. Beijing has kept export quotas tight since the crisis erupted, prioritizing domestic supply stability over being the world's emergency refiner.

The increase signals Beijing believes its own domestic supply is stable enough to spare some capacity. However, it is not a sign that China is throwing open the floodgates to rescue global markets.

Beijing is playing this strategically. China benefits from cheap discounted Russian and Iranian crude while selling refined products at crisis-premium prices.

The IEA's Verdict — And What Most Coverage Misses

The International Energy Agency has called this "the largest supply disruption in the history of the global oil market." Bigger than the 1973 Arab oil embargo. Bigger than the 1979 Iranian Revolution shock.

Most mainstream coverage treats this like a temporary price spike — a blip to be managed with strategic reserves and diplomatic maneuvering.

FTI Consulting's March 19 analysis documented the structural reality: Brent crude surged well above $100 per barrel within days of hostilities intensifying. Diesel spiked nearly 30%. Carriers without fuel hedges took immediate P&L hits. Fuel surcharges across truckload, LTL, and intermodal freight went up almost instantly and are staying up.

Until Hormuz reopens, the elevated costs appear durable.

What the Hormuz Closure Actually Means for Freight

The Strait of Hormuz normally carries 20-21 million barrels of oil per day, according to FTI Consulting. Container ships, bulk carriers, and LNG vessels all used those waters.

With Hormuz effectively closed, ships are rerouting around the Cape of Good Hope. That adds 10 to 14 days to Asia-to-Europe transit times, according to FTI Consulting. The same vessel fleet now delivers fewer cycles per year, reducing effective capacity.

Insurance war-risk premiums for Persian Gulf transits have spiked dramatically. Some carriers have exited the trade lane entirely.

The Northeast Asia-to-Europe Jet Fuel Route: What It Costs

The new Northeast Asia-to-Europe jet fuel pipeline is a direct consequence of the supply disruption. European buyers can't get Gulf product. South Korean and Japanese refiners have excess capacity and product. The economics — even with the longer route — now work.

This arrangement remains fragile. It depends on Northeast Asian refiners having available capacity, on stable shipping lanes through the Indian Ocean, and on European buyers absorbing the premium cost. Any one of those factors changing breaks the chain.

The global fuel system is running on emergency workarounds, and those workarounds are expensive for everyone who isn't selling the product.

Who's Paying for All This

Regular people. Airlines are paying more for jet fuel — and they will pass it to ticket prices. Truckers are paying more for diesel — and shippers pass it to consumers. European households are paying more for heating fuel. Asian manufacturers are paying more to ship goods.

Governments can release strategic reserves. China can bump export quotas by a few percentage points. Northeast Asian refiners can reroute cargoes. None of that changes the fundamental math: the world lost 20% of its daily oil trade flow through Hormuz, and no amount of rerouting fully replaces that.

The Outlook

The first jet fuel shipments from Northeast Asia to Europe signal that the crisis is structural enough to justify a months-long, expensive supply chain reconstruction. China's modest increase in export quotas reflects Beijing managing its own interests while collecting premium prices.

The IEA called it the largest supply disruption in history. The data backs that up.
