Gasoil Up 232%, Brent Up 117%: Distillate Returns Signal Deeper Hormuz Damage Than Crude Futures Show
European gasoil has more than doubled Brent's year-to-date gain, pointing to refinery-level disruption that crude futures positioning has yet to fully price.
Saudi Aramco began routing crude through ship-to-ship transfers off Sohar, Oman on Tuesday (2026-09-15) after a domestic pipeline outage pushed physical exports into scarcity pricing, Saxo Bank reported, tightening spot diesel markets further along the supply chain.7
That workaround may provide less relief than it appears. Saxo's analysis noted that additional Hormuz flows from Aramco may represent substitution for lost pipeline throughput rather than a net increase in global supply — meaning traders counting those Hormuz transit numbers as incremental barrels may be reading the same volume twice.7
Most positioning and commentary has focused on ICE Brent crude front-month, which was trading at $107.02 a barrel as of 2026-09-16, up roughly 50% since February according to Yahoo Finance data. But Bloomberg Commodity Index total-return data cited in Saxo's Tuesday (2026-09-15) report show European gasoil up around 232% year-to-date and NY ULSD up roughly 203%, against Brent's 117%. Distillates have outrun crude by nearly two to one.7,1
That spread reflects disruption deeper than crude supply alone. When Hormuz transit volumes slow and Saudi pipeline capacity is damaged simultaneously, middle distillate output falls first — refiners running below capacity cut diesel and jet fuel runs before other products. Diesel buyers cannot substitute the way gas-fired power generators can; the shortfall shows directly in spot.7
The confirmed traffic picture supports that reading. J.P. Morgan data cited by Rigzone showed Hormuz flows had fallen to just 5.1 million barrels per day as of Friday (2026-07-17), with a recovery that had "abruptly stalled." Bloomberg, citing Vortexa data, put 40 supertankers carrying 80 million barrels anchored and waiting for passage — crude sitting idle, not reaching refineries.4,2
Paper markets moved hard on diplomacy. When Washington-Tehran interim deal speculation built on Tuesday (2026-08-04), ICE Brent crude front-month dropped 5.3% to settle around $79 a barrel, its lowest since July 10. Trend-following commodity trading advisers cut their Brent long exposure to 36% of the book from 73% at the start of that session, according to Kpler's Bridgeton Research Group.5 Physical product markets moved differently. The gasoil-to-crude return gap in the Bloomberg data did not narrow.
Saudi pricing signals add a further complication. Aramco cut official selling prices for Asian-bound August cargoes by $11 a barrel, roughly double the expected reduction and the first time Saudi barrels in Asia traded at discounts to regional benchmarks since 2020, OilPrice.com reported.3 That scale of discount points to a seller clearing volume, not one rationing scarce supply — a pattern at odds with the physical tightness in distillate markets.
Dubai crude was quoted at $116.22 a barrel as of 2026-09-16, a roughly $9 premium over ICE Brent crude front-month. Sour Middle Eastern crude commanding that premium over Atlantic Basin barrels is unusual and points to localized supply stress in the grades that flow most directly from Gulf terminals.6
Goldman Sachs, as cited by Reuters, expects disruptions to persist into 2027. The IEA's latest monthly report showed global oil supply this year averaging 3.8 million barrels per day below last year's levels, with inventories declining at a similar rate since the conflict began.6,2 The EIA calculated that the Brent-WTI spread averaged $12 a barrel in March (2026-03), measuring how far US domestic supply has decoupled from Atlantic Basin pricing.1
The more telling number to track is not the next Hormuz transit count but refinery intake rates in Europe and Asia — specifically whether the 80-million-barrel tanker queue moves in a volume and cadence sufficient to restore middle distillate production. Until Kpler or Vortexa data show that backlog clearing at pace, a 115-percentage-point gap between gasoil and crude year-to-date returns remains the sharper measure of where this disruption is actually biting.7,2
