The Distillate System Is Quietly Breaking on the Edge of Paralysis

Several developments today point in the same direction. The global distillate system is tightening rapidly and the stress is now visible across physical flows, futures structures, and policy responses.

The most consequential development remains the Strait of Hormuz. Roughly 20 million barrels per day of crude and refined products normally move through this corridor, representing close to 20 percent of global petroleum trade. Recent tanker tracking data show how dramatic the disruption has become. Prior to the escalation the strait typically handled about 55 to 65 oil and gas tanker transits per day for vessels above 10,000 deadweight tons. In early March that number collapsed to fewer than 10 daily transits and now even less, with some days showing only one or two ships moving through the corridor. Even though some limited pre approved voyages are now being allowed to pass, traffic remains far below historical norms.

This effectively places Iran in the position of gatekeeper of the world’s most important energy chokepoint. Some non Iranian tankers have reportedly negotiated passage and a few cargoes destined for India have crossed, but most shipping companies still consider the corridor too dangerous for normal operations.

That tightening of physical flows is immediately visible in the diesel curve. ICE gasoil backwardation widened again today with the Apr/Jul spread near 288 dollars per ton while the Apr/Dec structure reached roughly 382 dollars per ton. Such extreme backwardation signals that the market is paying a large premium for prompt diesel supply.

Physical pricing confirms the signal. In Singapore 10ppm gasoil traded around 196.94 dollars per barrel while the cash differential surged to roughly 38.40 dollars per barrel, the highest level recorded for that benchmark. Refining margins for the same grade reached close to 46 dollars per barrel, showing exceptional profitability for middle distillate production.

Jet fuel markets are tightening even more aggressively. Jet fuel in Singapore traded near 200.17 dollars per barrel with a cash premium around 28.62 dollars per barrel. At these levels aviation fuel becomes the dominant operating cost for airlines and begins to threaten the economics of civil aviation if sustained.

Part of the Asian tightening reflects structural dependence on Chinese fuel exports. Bangladesh imports roughly 55 percent of its jet fuel consumption from China while the Philippines relies on China for about 65 percent of its diesel imports. Vietnam imports more than 50 percent of its jet fuel demand from Chinese refiners and Australia sourced roughly one third of its jet fuel imports from China last year. Tightening Chinese export flows therefore propagate quickly across Asia Pacific.

The implication is that distillate tightness in Asia will not remain regional. As Asia competes more aggressively for cargoes the tightening inevitably propagates westward through the refining system and eventually reaches the U.S. West Coast, which already depends heavily on imported refined products.

Europe added another policy signal today that reflects growing concern about fuel costs. Germany introduced a rule limiting retail fuel price adjustments to once per day. The policy aims to reduce intraday price volatility for consumers but it also restricts how quickly retailers can respond to wholesale market movements during periods of supply stress.

Biofuel markets were also active today. The ICE OPIS D4 RIN December 2026 future traded around 1.56 dollars per RIN, rising roughly 5 percent on the session after trading as low as 1.50 earlier in the day.

Washington is now turning its attention back to the sector. A meeting scheduled next Friday at the White House will bring together agricultural and biofuel stakeholders to discuss supply and policy. The meeting comes as distillate markets tighten globally and blending economics become more relevant again for both biodiesel and renewable diesel.

European biofuel markets remain firm against this backdrop. Broker indications place RME in ARA around 1487 to 1507 dollars per ton for March loading while UCOME trades near 1507 to 1527 dollars per ton. With ICE gasoil near 1020 dollars per ton equivalent, biodiesel maintains substantial premiums supported by blending mandates and strong diesel demand.

Feedstock markets moved for different reasons today. Agricultural futures sold off after news that the expected United States China summit had been postponed, pushing expectations for renewed Chinese soybean purchases further into the future and triggering selling pressure in soybean futures.

Yet the physical soybean oil market showed modest strength. Export offers from Brazil indicate Paranagua soybean oil premiums strengthening to roughly minus 900 to minus 1100 points versus Chicago soybean oil futures compared with minus 1250 to minus 1450 points for later shipments.

Part of this firmness may reflect Brazil’s tightening diesel situation. The country imports roughly 25 to 30 percent of its diesel consumption and Petrobras controls about 55 percent of domestic diesel production. During the soybean harvest season diesel demand for trucking and agriculture rises sharply, forcing Petrobras to release additional supply including an auction of approximately 20 million liters of diesel in southern Brazil. Tight diesel availability during harvest increases reliance on biodiesel blending and supports demand for vegetable oils.

Taken together the message from the market is becoming difficult to ignore. When tanker traffic through the world’s most important energy chokepoint collapses from roughly 60 ships per day to fewer than 10, jet fuel trades above 200 dollars per barrel, Singapore diesel premiums approach 40 dollars per barrel, and ICE gasoil backwardation stretches toward 400 dollars per ton, the global distillate system is operating under severe strain.

Europe remains the most exposed region in this environment. The continent runs a structural diesel deficit and relies heavily on imports. If tightening continues while supply routes through the Middle East remain uncertain and Asian demand absorbs more cargoes, the possibility of diesel rationing in parts of Europe becomes increasingly inevitable with serious implications for Biodiesel demand.
