Shipping Fuel Oil Faces 218,000 Barrel Daily Shortfall as Diesel Demand Squeezes Refinery Output
War-driven refinery losses across the Middle East and Russia are forcing producers to prioritize diesel, starving the shipping industry of fuel oil at a rate not seen since 2025.
The global shipping industry is staring at a fuel oil shortfall of 218,000 barrels per day in the current quarter, according to Energy Aspects data cited by Reuters, marking the first such deficit since 2025 — and one that dwarfs the 6,000 barrel daily gap recorded then.7
The cause is a straightforward competition for refinery output. With diesel commanding premium margins after sustained attacks on Middle Eastern and Russian processing infrastructure, refiners are tilting their slates toward the higher-value product and leaving less fuel oil for ship operators. Asia is expected to absorb the worst of the squeeze.7
The scale of the underlying damage helps explain why the arbitrage between refinery inputs and shipping fuel has broken down so sharply. The IEA has assessed that roughly a fifth of global refining capacity — some 9.6 million barrels per day — has been knocked offline by hostilities, according to Reuters' reporting on Monday (2026-09-07). That figure sits behind nearly every distorted product spread visible in the market right now.7
A Rystad Energy analyst told Reuters that fuel oil supply would remain critically tight through the third quarter, citing the protracted nature of Middle East supply disruption. The assessment aligns with Goldman Sachs, which stepped up diesel warnings in late August (2026-08-31), more than doubling its forecasts for diesel refining margins and flagging "rising strikes on refineries in the Middle East" as the proximate cause.7,6
The product export picture from the Gulf underscores how incomplete any recovery has been. Goldman analysts noted that while Persian Gulf crude exports have recovered to roughly 70-80% of pre-war levels, product shipments remain at only 40%. Crude moving without the downstream processing to convert it means the physical product markets — diesel, fuel oil, kerosene — stay undersupplied even as headline crude prices reflect some demand recovery.6
ICE Brent crude front-month was trading at $96.28 per barrel as of 07:10 UTC on Monday (2026-09-07), while NYMEX ULSD heating oil front-month stood at $4.61 per gallon. The divergence between crude and product pricing reflects precisely the dynamic flagged by Australian analysts in late August (2026-08-25): crude can get cheaper while the products consumers and ship operators actually need remain expensive, because the missing link is refining throughput rather than raw crude supply.5
Asian refiners have felt this most acutely. Gulf crude — their preferred feedstock — has largely disappeared from available supply, forcing a throughput reduction of 3.5 million barrels per day, or about 12%, according to Economist reporting from May (2026-05-17). Crude inventories tracked by Kayrros using satellite data had already dropped 13% to 545 million barrels at that point. The months since have brought little structural relief.2
European refiners have not been passive bystanders. They converted more crude toward kerosene output while pulling heavily on diesel imports from the U.S. Gulf and east coasts, which in turn pulled American diesel stocks down 11% in five weeks, per the same Economist data. Germany's stockpiling agency EBV issued a tender in early July (week of 2026-07-06) for over 760,000 barrels of diesel to refill strategic reserves — additional demand pressure on an already depleted pool.2,4
The price signals in the physical diesel market have become extreme. A commodities trader cited in Economist reporting said some diesel cargoes were changing hands at $600 per barrel, up from $300 the prior week at the time of reporting in May (2026-05-17). If that trajectory has continued, or even partially reversed, the current tightness in fuel oil markets suggests the broader products complex has found no durable relief.2
Since the conflict began, observable global oil stocks fell by a cumulative 246 million barrels through April, according to OGJ citing conflict-period data — a 129 million-barrel draw in March (2026-03) followed by 117 million barrels in April (2026-04), running at roughly 3.9 million barrels per day. The IEA's planned release of 400 million barrels, the largest coordinated drawdown in the body's history, was designed to absorb that shock, but product-specific supply problems tied to refinery damage are not cured by releasing crude.3,1
That asymmetry is the unresolved constraint for shipping markets. Bunker fuel buyers in Asia cannot convert crude reserve releases into fuel oil without functional refinery capacity, and with 9.6 million barrels per day of global processing still offline, the bottleneck sits in the middle of the supply chain rather than at either end. Whether Middle Eastern product export volumes can recover meaningfully from their current 40% of pre-war rates before year-end is the number worth tracking.7,6
