Morning Highlights WTI Up 5.6% on the Week to Brent’s 0.4% as IEA Diesel Release Pulls European Margins Lower

Brent (December) $105.70 | WTI (November) $97.34

Brent -$0.22 (-0.2%), WTI -$0.63 (-0.6%). For the week, Brent is up 0.4% and WTI 5.6%. European diesel margins fell nearly 2% to $78.67 a barrel after the IEA agreed Thursday to release more than 20 million barrels of diesel. Kpler says intensified Iranian attacks drove Gulf crude flows sharply lower.

Bottom Line

The diesel release is reaching margins first, not supply. The IEA agreed Thursday to speed up its stock release, including more than 20 million barrels of diesel, and Saxo’s Ole Hansen pointed to the pledge to release the remaining 100 million barrels under the March agreement, plus the shadow fleet sanctions discussion, as weighing on sentiment. His view is that the release is unlikely to ease the diesel tightness. European margins are down from a September high of $95 a barrel but still high. India added a product change: from today it cut its diesel export duty to 8.5 rupees per liter from 16 for the next two weeks, which could encourage more supply to the international market. It also raised the gasoline export duty to 2.5 rupees from 0.5, which looks aimed at discouraging gasoline exports, and left jet fuel at 10.5 rupees. India reviews the duties every two weeks.

Gulf flows are the counterweight. Kpler analysts said Thursday that intensified Iranian attacks drove Gulf crude flows sharply lower, and that without a comprehensive political deal they expect a slower and more uneven recovery in Hormuz flows. That cuts into the September recovery in the IEA’s October report. Iran says it is stepping up strikes in response to the US blockade of its ports and the tougher sanctions imposed last month, and Reuters reports attacks around the strait have surged over the past 10 days. The Saudi-Houthi front widened too. The Houthis fired missiles at the presidential palace complex in Aden on Thursday, killing two guards, and the Saudi-led coalition detailed dozens of attacks on Saudi infrastructure. The sources don’t name the sites. Hansen said the market is caught between persistent supply disruption risks and relief headlines, which fits the flat Brent price.

WTI and Brent are moving apart. WTI settled up more than 3% Thursday after a larger-than-expected draw in US crude stocks, with production shut in by the hurricane, which pushed its weekly gain to 5.6% against Brent’s 0.4%. Jeff Currie of Real Macro, on Bloomberg Television, said Brent has become a “vibe contract” that is “not connected to the real world anymore.” The contract’s usefulness for hedging is the issue. Dated Brent is near $130 a barrel per Bloomberg, and Brent open interest earlier this month was its lowest since March 2025. Currie attributes part of the gap to Brent’s cash settlement, against WTI’s physical delivery, and says the disconnect creates “unpriceable risk” for hedgers. The open interest figure is the hard data point. The rest is Currie’s view.

Ukraine’s refinery strikes are now a dispute between Washington and its allies. Trump called Ukraine’s resumption of strikes a “disgrace” in a Newsmax interview and said, “All he’s doing is making the world oil price higher.” EU leaders rallied around Zelenskiy at a summit in Brussels, where he said Russia isn’t ready to end the war and Ukraine must prepare for winter. Russia broke with its usual practice and showed the Ryazan refinery on state TV for the first time in the war, with a small plume and no fire visible. Putin said Ukrainian strikes had caused little damage and vowed a response. Ukraine says it paused for three days after Trump’s energy ceasefire announcement and resumed because Russia kept hitting its power plants.
