Brent fell more than 2% after futures reopened Sunday night and was trading above Friday's settlement by the U.S. morning. Heating oil and European gasoil stayed lower, the part of the barrel most exposed to Ukraine's strikes on Russian refineries, to a new push for emergency diesel releases and to Friday's Russian diesel deal.
The oil market gave its verdict on President Trump's weekend truce announcement in two parts. Crude decided it would believe it when it saw it. Diesel stayed lower, though the truce was not the only news behind that.
Brent crude settled at $104.72 a barrel on Friday. When futures reopened at 6 p.m. Eastern on Sunday it briefly rose to $105.63, then slid to $102.39 by about 9 p.m., a drop of more than 2%. By 4:45 a.m. Eastern on Monday it had recovered to about $104.94, slightly above where it began, and by about 7 a.m. it was near $106, up about 1.3%. U.S. crude followed the same path, falling to $89.65 before returning to about $91.92 by 4:45 a.m.
Heating oil futures, the U.S. diesel benchmark, did not make the round trip. They traded near $4.65 a gallon at 4:45 a.m., down about 1.9%, and were still down about 0.9% at about 7 a.m. European gasoil futures were down about 4.6% at $1,415 a metric ton by mid-morning in London.
What was announced
"Effective immediately, there is an ENERGY CEASEFIRE in the War between Russia and Ukraine. Both parties have agreed. Do not break it!" Mr. Trump posted on Sunday. He gave no details on scope, start time or verification.
Neither government has described the arrangement in those terms. Ukrainian President Volodymyr Zelensky said the announcement was news to him and that Ukraine would agree if Russia did. "Ukraine is ready to refrain from striking Russian energy infrastructure, and we count on the same readiness from Russia," he said. Hours after the post, Ukrainian officials reported Russian strikes on a power plant in Kyiv and on a combined heat and power plant in Kharkiv, and Ukraine's foreign minister said Russia had broken the truce. On Monday, the Kremlin said contacts on an energy truce were continuing and that it would say more when it had something to report, but it did not confirm a deal or its scope.
The two sides also appear to be describing different deals. A White House official said the U.S. understanding covers oil refineries. Kyiv wants power plants and the grid included. It is the second energy truce Mr. Trump has declared in about a month without confirmation from Moscow.
Why diesel and crude may have split
One explanation follows the plumbing. Ukrainian drone attacks have targeted Russian refineries, which make diesel, not oil fields. A pause on those strikes would add refined fuel to the market long before it changed crude supply. If a refinery-only truce held, that is the channel through which it would work.
Diesel also had other news behind it, some of it predating the truce post. On Friday afternoon, Mr. Trump said Russia would immediately supply more than 300,000 metric tons of diesel to U.S. and global markets under a deal with Moscow, with more to follow, and diesel futures fell that day. Eurasia Group's analysts estimate that, at current U.S. rates of distillate use, the opening shipment would last about half a day. A bipartisan group of six senators urged the administration to reverse course.
The International Energy Agency also intervened. In a letter to member governments ahead of its Oct. 15 governing board meeting, Executive Director Fatih Birol asked countries that have not fully delivered the stock releases pledged in March to "accelerate the remaining releases," prioritizing diesel, and asked all members to assess whether additional diesel releases are needed. Members have released about 325 million barrels under the March action, according to the IEA.
What kept crude up
Crude had reasons to hold its ground that had nothing to do with Ukraine. Saudi Arabia's main airport in Riyadh was struck again on Sunday, a tanker was hit by a drone off the Omani port of Sohar, and Iran rejected Washington's latest reply on reopening the Strait of Hormuz. Brent remains well above $100 on Gulf risk alone.
Two readings
The first reading is that the diesel premium is starting to deflate because relief is arriving from three directions at once: licensed Russian cargoes, a possible halt to refinery strikes and accelerated emergency stocks. On that view crude's recovery is about the Gulf and does not contradict the diesel move.
The second is that diesel is pricing a headline rather than barrels. Moscow has not confirmed anything, strikes on energy sites continued after the announcement, Kyiv's acceptance is conditional and the diesel purchase faces opposition in Congress. If the truce fails in the open, the premium could rebuild quickly.
What decides it
A statement from the Kremlin on scope, the record of strikes on energy facilities over the next two days and the IEA board's decision on Thursday will show whether Monday's diesel discount holds. September consumer prices on Wednesday will show how much of the fuel shock has already reached the inflation data. Russia's ban on diesel exports by producers, partly lifted over the weekend, is set to expire on Oct. 31.
