Europe stays bid as Saudi supply risk spreads into Asian gasoil

Diesel prices are likely to stay elevated as Europe’s relief options narrow, Red Sea freight surges and both Med and Asian balances start pricing supply risk again. View is long both Europe and Singapore diesel Nov/Dec time spreads, currently at $71/mt and $10/bbl respectively.

Rotterdam diesel relief is looking narrow. The arb screen is mostly closed across late-October and November delivery windows, with Yanbu the clearest workable route and Houston MR only selectively open from late October.

This makes Yanbu the key relief valve. If the Saudi East-West crude pipeline disruption is short-lived, Yanbu can likely keep exports moving through storage for a few days. But if the disruption lasts longer and starts affecting crude availability or refinery runs, Europe loses one of its cleanest diesel supply routes.

The Mediterranean is the most exposed region. Around 70% of Yanbu diesel flows into Europe in August went to the Med, so any issue with Yanbu exports or Red Sea transit would likely show up first in Med pricing.

Russian restrictions make the Med even more vulnerable. With Russian diesel exports constrained, Turkey is already short of its usual supply pool and needs replacement barrels from Yanbu, WCI, the USGC and other non-Russian origins. That leaves fewer alternative barrels for the rest of the Med.

WCI-to-Turkey is another pressure point. West Coast India exported close to 400 kt of diesel to Turkey across July and August, with most barrels moving through the Red Sea. If that route becomes risky, Turkey either faces longer Cape of Good Hope voyages or has to compete harder for alternative supply.

Freight is now slowing the corrective. TC20 has surged to around $183/mt, with only nine open vessels versus a 14-ship baseline, and the FSD model still points higher over the next two weeks. With Hormuz talks postponed and crossings still in single digits, LR2 owners have strong prompt leverage and September-October AG loading cover looks urgent.

This matters because AG, Yanbu and WCI are exactly the barrels Europe needs. Even when the arb is technically open, higher TC20 raises the delivered cost and slows the flow response. Europe therefore has to keep paying a wider premium, especially into the Med.

Reports that Trump urged Zelensky to stop attacking Russian refineries fit the same diesel story. The Atlantic Basin is already short of middle distillates, and further Russian refinery losses would keep replacement demand elevated across Europe, Turkey and the Med.

The Asian diesel picture is also turning more complicated. Earlier, higher exports from China, Korea and Japan kept Asia better supplied and created a sharp East-West divergence. Europe was scrambling for barrels while Asia had supply levers, pushing October E/W to around minus $105/mt, with the spread now at minus $65/mt.

But Asia is no longer immune to the risk premium. Fears around crude availability and Saudi supply disruption have started lifting Asian diesel as well, with E/W bouncing strongly from the lows. The West premium remains, but the market is now pricing the risk that Asian refiners could also face feedstock constraints if Middle East flows become less reliable.

China remains the key Asian supply watch. Runs have picked up recently and exports helped loosen the regional diesel balance. But if crude availability tightens because of Saudi or wider Middle East disruption, refiners may not maintain the same run pace. That could slow China’s export momentum and remove one of Asia’s main supply cushions.
