Kyiv Ends Its Refinery Strike Pause as US Weighs Sanctions Relief for Shadow Fleet Tankers

Brent -$1.56 (-1.5%), WTI -$0.07 (-0.1%), reversing Wednesday’s gains. A US official said the administration is considering easing sanctions on some shadow fleet tankers to cut freight rates. Ukraine resumed strikes on Russian refineries with a fire at the Ryazan refinery, ending a pause that began with Trump’s energy ceasefire announcement Sunday. A container ship and a dry bulk carrier sank near Hormuz in the past 24 hours after being hit by projectiles, maritime officials said Wednesday.

Bottom Line

The shadow fleet discussion is about freight, not oil supply, and nothing has been decided. A US official said the administration is considering letting “legal oil” move on previously sanctioned vessels, meaning crude or products not sanctioned by Washington, as opposed to Russian and Iranian oil. Companies would have to apply to the Treasury to use the tankers, and the stated goal is to get more refined products and crude out of the Gulf. Energy Aspects said Energy Secretary Chris Wright raised the idea in a video to the World Petroleum Congress in Riyadh. Reuters could not obtain the full video or a transcript, and the Department of Energy said it was not available. The department said any relief would not help Russia move oil, and Treasury referred questions to it. Energy Aspects does not expect a large freight effect: most sanctioned tankers have been trading actively for three months, so they add little mainstream capacity overnight, though a small number could become available for Hormuz shuttle runs. Maritime industry sources said insurers remain bound by EU and UK rules, which limits any broad easing. This follows Trump’s temporary lift on Russian diesel sanctions through April 7, which drew criticism from Zelenskiy, European leaders including Italy’s Meloni, and some Republican senators.

Ukraine’s decision to resume refinery strikes cuts against the Russian diesel story. Kyiv had refrained from hitting Russian refineries since Sunday’s announcement. Zelenskiy told the Financial Times Thursday, “The block is out. We’re done,” after saying Russia’s continued strikes left 600,000 people without power Wednesday. Ryazan governor Pavel Malkov said a major drone attack started a fire at a refinery in his region, with damage being assessed. Zelenskiy linked the move to what he called a withdrawal of US intelligence. He said Ukrainian officials were warned that Washington would block intelligence unless strikes on Russian energy stopped, that the slowdown of Starshield service was “not a technical problem, it was the will,” and that he would only halt energy strikes in return for more US-made Patriot interceptors. Musk said on X that the US government owns and controls Starshield and decides any speed limits. Trump called Saturday for Ukraine to replace Zelenskiy. Yesterday the IEA said Russia’s easing of diesel export restrictions is unlikely to change the global balance because Russian refinery capacity is the constraint. Renewed strikes make a quick recovery less likely.

The Hormuz attacks are still escalating. Reuters reports that attacks around the waterway have surged over the past 10 days, with Iran saying it is stepping up strikes in response to the US blockade of its ports and the tougher sanctions imposed last month. The container ship and the dry bulk carrier sank in separate incidents, per maritime officials, and the container ship’s cause was reported yesterday as a mine, so the accounts differ. MUFG’s analysts said the Saudi-Houthi conflict keeps a geopolitical premium in the market but that energy infrastructure has not been attacked in the last several days. That fits Tuesday’s Dhahran strike hitting an office tower, not a producing or export facility, and the Houthis have said they will keep targeting oil sites.

US inventories add a counter-signal. API data showed crude stocks fell 11.1 million barrels in the week ended October 9, far more than analysts polled by Reuters expected, with distillate stocks lower and gasoline higher. WTI barely moved today against a Brent decline of $1.56, consistent with that draw supporting US crude, though the sources don’t link the two. Official EIA figures are due at noon ET, a day late because of the Columbus Day holiday.
