Ukraine has resumed drone strikes against Russian refineries, hitting three large plants over three consecutive nights, ending a roughly two-week pause under pressure from the Trump administration. Kyiv is betting that striking Moscow's oil revenues just days before the US midterm elections is worth the diplomatic cost. According to Ukrainian monitoring agency Dnipro Osint and Russian state media, the first round of strikes occurred on the night of October 30, igniting Rosneft's Novokubyshevsk refinery in the Samara region; this was followed by attacks on the Ufa industrial zone, home to the Bashneft-Novoil refinery; and on the night of November 1, Lukoil's NORSI refinery in Kestovoy—one of Russia's largest refineries—was also targeted. The three plants collectively process approximately 33 million tons of crude oil annually, representing about 10% of Russia's refining capacity, but this figure reflects the targeted capacity, not the confirmed output loss. Ukrainian drone manufacturer Fire Point said it participated in the strikes in Novokubyshevsk and Kestov, including hitting a diesel hydrotreating unit.

The background of the suspension: US pressure, easing of sanctions, and electoral considerations

According to media reports, Ukraine has not attacked Russian refineries since October 15 and has not targeted any Russian oil infrastructure since October 20, due to repeated pressure from US officials on Kyiv to halt the attacks. Trump blamed the high global fuel prices on these attacks—which energy experts largely attribute to the US-Iran conflict—and lifted US sanctions on Russian diesel last month. European allies reportedly urged Kyiv to wait until after Tuesday's US midterm elections before taking action. Ukrainian officials told the media they never agreed to the US's demand for a 30-day suspension. The Kremlin stated that Kyiv is now ignoring Washington's wishes. President Zelensky has not acknowledged the refinery attacks, seemingly to avoid angering Washington. He stated that Ukraine has an obligation to respond to Russia's escalating attacks on its energy system. Russian drones and missiles killed at least 27 civilians across Ukraine on Thursday, and Sunday night's attacks left hundreds of thousands of homes without power, with Kyiv facing blackouts of up to 10 hours. Zelensky stated that Ukraine hopes to exchange halting the refinery attacks for stronger protection of its own energy infrastructure.

Refined oil supply returns to focus: Damage to diesel hydrotreating units draws attention to exports and refining capacity.

The resumed strikes have brought Russia's refined petroleum product supply back into focus, particularly diesel—at a time when the US-Iran conflict has tightened global energy markets. Damage to processing units such as the Novoo Kubyshevsk diesel hydrotreating plant, if the shutdown continues, could curb Russian fuel exports and support refining margins, although the extent of the damage has not yet been independently verified. If domestic processing is disrupted, Russia may also divert more unrefined crude oil to exports. Political uncertainty also exists: Washington has pressured Kyiv to halt these strikes, blaming high fuel prices, so any US response after Tuesday's midterm elections could alter the flow of Russian energy and the outlook for sanctions.

Diplomacy and upgrading go hand in hand: Trilateral talks imminent, territorial disputes limit room for breakthroughs

Diplomatic efforts are proceeding alongside escalating tensions. Trilateral talks between Russia, Ukraine, and the United States are expected later this month, and the Kremlin has stated that President Putin is willing to speak directly with Zelensky. However, Russia's core territorial claims remain unchanged, limiting the prospect of a broader breakthrough. This comes after OPEC+ maintained its December production target for the third consecutive month amid ongoing disruptions in the Strait of Hormuz; Iran claims two oil tankers struck landmines in the Strait of Hormuz and has proposed a two-day reopening plan.

Russia extends diesel export ban until the end of January 2027

According to the Russian government, the ban on diesel exports by diesel producers has been extended to the end of January 2027. A relevant resolution has been signed, extending the ban on direct producers exporting diesel, marine fuel, and gas oil from Russia until January 31, 2027 (inclusive). The report indicates that this decision aims to maintain stability in the domestic fuel market. Meanwhile, Russian Deputy Prime Minister Novak stated on October 30 that while extending the overall diesel export ban, Russia is developing exceptions for some suppliers, allowing them to supply the international market; such easing measures were implemented in October, and further easing arrangements are planned for November.

Editor's Summary

Ukraine struck three major Russian refineries within 72 hours, targeting a combined annual capacity of approximately 33 million tons, representing about 10% of Russia's total refining capacity, ending a two-week shutdown under US pressure. This move has brought Russian refined product supplies, particularly diesel, back into focus. Damage to secondary processing units such as diesel hydrotreating, leading to continued shutdowns, could suppress exports and support refining profits. Actual output losses still need independent verification, and Russia may partially offset this by increasing crude oil exports. Political variables are concentrated on the US policy response following the midterm elections, which could affect the implementation of sanctions and the flow of Russian energy. Diplomatically, trilateral talks are imminent, but unresolved core territorial disputes limit the potential for breakthroughs. The energy market will continue to oscillate between supply disruptions and diplomatic hopes, with short-term prices and flows remaining uncertain.

Frequently Asked Questions

Q: Which three refineries did Ukraine target this time? How was the capacity calculated to be approximately 10% of Russia's total capacity? A: The three targets are Rosneft's Novokubyshevsk refinery in Samara Oblast (approximately 8.8 million tons per year), Bashneft-Neuer (Ufa, approximately 7 to 7.3 million tons per year), and Lukoil's Kestovo NORSI refinery (approximately 15 to 17 million tons per year). This totals approximately 33 million tons. Russia's total installed refining capacity is approximately 650 to 670 million barrels per day, equivalent to approximately 320 to 330 million tons per year. 33 million tons corresponds to approximately 10%. This percentage comes from the Ukrainian monitoring agency Dnipro Osint and publicly available design capacity data, reflecting the targeted nominal capacity, not the confirmed actual losses. Damage to key units such as diesel hydrotreating plants may amplify the short-term impact, but the complete shutdown time and repair progress still need further verification. Q: Why did Ukraine previously suspend attacks on Russian refineries, but then resume them before the midterm elections? A: Ukraine has not attacked Russian refineries since October 15, and has not attacked any Russian oil infrastructure since October 20. It has been reported that US officials repeatedly pressured Kyiv to halt the operations, and the Trump administration attributed some of the global fuel price pressure to these attacks and had previously lifted sanctions on Russian diesel. European allies also suggested waiting until after the US midterm elections before taking action. Ukrainian officials stated that they never formally agreed to the 30-day suspension request. The resumption of attacks occurred days before the election, with Kyiv betting on gaining strategic space by targeting Moscow's oil revenues while responding to Russia's continued attacks on Ukraine's energy system. Zelensky did not directly acknowledge the operations but emphasized an obligation to respond to Russian attacks. This move demonstrates Kyiv's balancing act between US pressure and its own strategic needs. Q: What does damage to the diesel hydrotreating unit mean for Russian refined petroleum product exports and the market? A: Targets in Novokubyshevsk and other locations reportedly hit the diesel hydrotreating unit. This unit is a key secondary processing unit for producing standard diesel. If the shutdown continues, it could directly reduce diesel production, suppress Russian fuel exports, and support refining profits in the short term. Russia has previously restricted some fuel exports to ensure domestic supply in response to the crackdown. An assessment by the International Energy Agency shows that the continued crackdown has significantly reduced Russian refining throughput. If domestic processing is disrupted, Russia may divert more unrefined crude oil to exports, partially offsetting losses in refined products. The global market is already tightening due to tensions in the Middle East and elsewhere; this added disruption could further impact supply expectations and prices for fuels such as diesel. The actual impact will depend on the recovery time and the availability of spare capacity. Q: How might the US midterm elections affect this situation and energy sanctions? A: The US response after the election is a key political variable. Washington previously pressured Kyiv to halt the refinery crackdown and attributed some of the fuel price pressure to it. The election results may influence the Trump administration's support for Ukraine, the implementation of sanctions against Russia, and its energy policy orientation. If the US further exerts pressure or adjusts sanctions, it could alter the export routes and flows of Russian refined products. Conversely, if support continues, the Ukrainian crackdown may continue. The energy market will closely monitor the impact of post-election signals on the tightening of sanctions and the flow of Russian energy. The trilateral talks are expected to be held this month, but Russia's core territorial claims remain unchanged, limiting the scope for a diplomatic breakthrough. Overall, post-election policy will directly impact Russia's energy revenue and global fuel supply expectations. Q: What is the current progress of diplomatic efforts? Is there any hope for easing the energy and military standoff? A: The Russia-Ukraine-US trilateral talks are expected later this month, with the Kremlin stating that Putin is willing to speak directly with Zelensky. Zelensky's side emphasizes its desire to exchange halting refinery attacks for stronger protection of its energy infrastructure. However, Russia's core territorial claims remain unchanged, limiting the prospect of a broader breakthrough. Meanwhile, OPEC+ continues to maintain its production targets amid disruptions in the Strait of Hormuz, while Iran has proposed reopening oil tankers after they struck mines. Diplomatic channels remain operational, but military strikes and energy disruptions are proceeding in parallel. In the short term, supply disruptions and diplomatic hopes will continue to be a tug-of-war, and the energy market needs to simultaneously assess actual production losses and negotiation progress. A real easing still depends on whether a balance can be found between the core demands of both sides.
