How Ukraine made Russian oil its top target

Introduction: a campaign, not an accident

Two refineries, one same logic

Saturday night, Ukrainian drones once again struck at the heart of Russia. According to Bloomberg, Ukraine hit the Slaviansk-na-Kubani refinery in the Krasnodar region, as well as a site in Yaroslavl, roughly 700 kilometers from the Ukrainian border. President Volodymyr Zelensky confirmed both strikes on social media, calling them "long-range sanctions."

This kind of strike has become so frequent that it risks going unnoticed in the constant flow of news about this war. That is precisely what I want to avoid in this investigation: showing that behind every isolated explosion lies a coherent, patient, and devastatingly effective strategy against Vladimir Putin's war economy.

Why this investigation now

The repeated strikes on Russian oil infrastructure deserve serious attention, because they are changing the very nature of the conflict. This is no longer just a frozen trench war, but an economic war where every refinery hit directly weighs on the Kremlin's ability to fund its military effort.

I'll say it plainly: this oil war is becoming the most decisive front of the conflict, far more so than the few square kilometers that change hands each month in the Donbas.

What the Slaviansk-na-Kubani target reveals

A strategic refinery for Crimea

The Slaviansk-na-Kubani refinery, owned by the Slavneft-YANOS group Slaviansk EKO, processes nearly 4 million tons of crude per year with a capacity of about 100,000 barrels per day, according to Bloomberg. It supplies a significant share of the fuel destined for occupied Crimea and for exports through Black Sea ports.

The site had already been hit in January, confirming that Kyiv methodically returns to strike the same targets until their operational capacity is durably reduced. One person was killed and one wounded, according to governor Veniamin Kondratyev, following this latest strike.

This repetition is no accident: it is a deliberate military doctrine designed to progressively wear down infrastructure that Moscow wrongly believed could absorb strikes indefinitely.

The strategic reach of the Yaroslavl strike

A signal sent to all of inland Russia

Striking a target 700 kilometers from the Ukrainian border, as in Yaroslavl, sends a clear message: no Russian region, however far from the front, is safe from Kyiv's drones. Governor Mikhail Yevrayev confirmed a drone attack that forced the temporary closure of roads toward Moscow.

Russian authorities have remained largely silent about the exact extent of the damage, a silence that, according to several analysts cited by Al Jazeera, reflects a desire to downplay a vulnerability that is embarrassing for the Kremlin's image.

Russian silence about these strikes sometimes speaks louder than any official statement. It is the tacit admission of a power that no longer fully controls the narrative of its own vulnerability.

A methodical escalation over several months

A frequency that has doubled

According to data compiled by Reuters, the frequency of drone strikes on Russian refineries has doubled since the start of the year, causing complete or partial refining shutdowns. On June 18, a record assault targeted Moscow itself, with nearly 194 drones shot down according to mayor Sergei Sobyanin, some of which reached the capital's refinery.

The International Energy Agency estimates that this pressure will continue to weigh on Russian refining capacity at least until mid-2026, according to Bloomberg. This is proof that this Ukrainian strategy is producing measurable, lasting effects, not merely one-off symbolic gestures.

When an agency as cautious as the IEA acknowledges the scale of the impact, it becomes impossible to dismiss this campaign as a mere Ukrainian communications operation.

Vladimir Putin's unusual admission

A "certain deficit" acknowledged publicly

Vladimir Putin admitted, during a televised interview reported by the Chicago Tribune, that Russia is experiencing a "certain deficit" of fuel, while promising to strengthen security at oil sites. He accused Kyiv of trying to "create divisions" within Russian society.

On the ground, lines are forming at gas stations and several regions have introduced rationing, according to Fortune. In Crimea, the free sale of gasoline to the public has even been suspended, with fuel reserved for emergency vehicles.

Watching Putin acknowledge a fuel shortage, however downplayed in his remarks, is a revealing moment for anyone who has followed this war from the start: the Kremlin's constant lying is starting to crack under the weight of facts.

The economic impact documented by the numbers

Oil revenues in continuous decline

According to an analysis by the Centre for Research on Energy and Clean Air cited by the Guardian, revenue from Russian fossil fuel exports has fallen 13% compared to pre-war levels in 2025. The International Monetary Fund projects growth of just 1.1% for the Russian economy in 2026.

The increase in Russian VAT, from 20% to 22% at the start of the year, confirms that the Kremlin's budget is stretched thin, forced to make up through domestic taxation for the losses caused by sanctions and Ukrainian strikes.

Every extra VAT point paid by a Russian pensioner is, indirectly, a consequence of the war Putin chose. The Russian people are already paying that bill, whether they know it or not.

The price paid simultaneously by Ukrainian civilians

Reprisals that only ever target legitimate military objectives

The same day, a Russian air bomb killed two people in Zaporizhzhia, according to regional administration head Ivan Fedorov. Ukraine's air force reported intercepting 125 drones and seven missiles out of the 142 drones and eight missiles launched by Russia that night.

This asymmetry must be named clearly: on one side, an invading army striking civilians; on the other, a nation targeting the economic and military levers of its aggressor in self-defense.

I reject any false equivalence between these two sides. There is an aggressor and a victim defending itself intelligently, and conflating the two would be a moral failure as much as an analytical one.

The authoritarian axis behind Russian resistance

Growing dependence on Beijing

According to a study published by the Kiel Institute, China now accounts for roughly 35% of Russia's total foreign trade and supplies the vast majority of dual-use goods entering the country. This growing dependence illustrates a major strategic shift: the more Western sanctions and Ukrainian strikes weigh on Moscow, the more the Kremlin becomes dependent on Beijing to keep its war machine running.

The liquid reserves of Russia's sovereign wealth fund fell from 6.5% of GDP at the start of the war to just 1.8% in April 2026, according to the same institute. Oil and gas revenues dropped 45% year-on-year in the first quarter of 2026, a collapse that confirms, with hard numbers, that Ukraine's deep-strike strategy is producing considerable cumulative effects on the Kremlin's finances.

This growing dependence on China should worry every Western strategist. A Kremlin on the ropes, financed and equipped by Beijing, is living proof that the axis of authoritarian regimes tightens as each of its members grows economically weaker.

An exhausted workforce, inflation looming

The Kiel Institute report also notes that the main constraint on Russia's war economy is no longer access to money, but access to people, technology, and productive capacity. Labor shortages are hitting record levels, and any further increase in military spending risks producing more inflation rather than a real rise in weapons production.

This diagnosis, drawn up by independent economists rather than Ukrainian propaganda, confirms that the campaign against refineries fits within a broader context of structural exhaustion of the Russian economy, where every new front of pressure, energy or financial, worsens an already fragile situation.

It bears repeating relentlessly: an economy short on hands and technology does not recover through triumphalist speeches on state television. Putin may deny reality in front of the cameras, but the Kiel Institute's numbers tell a very different story.

This structural picture also explains why sanctions enforcement now matters as much as sanctions design. A regime that cannot replace lost machinery, cannot retrain lost workers fast enough, and cannot substitute foreign components on short notice is a regime running on borrowed time, propped up almost entirely by Beijing's willingness to keep supplying it.

Conclusion: a war also being won in the tanks

A strategic bet that is paying off

This investigation confirms an underlying trend: Ukraine has made economic warfare an essential component of its resistance, with measurable results on Russian oil revenues and on the daily life of the Russian population itself. Every refinery hit, every line forming outside a Siberian gas station, every VAT hike imposed on Russian citizens, are all direct consequences of a Ukrainian strategy built for the long term.

What remains to be watched

It remains to be seen whether the West will know how to support this dynamic by intensifying its own sanctions regime, particularly against Russia's shadow fleet and the Chinese suppliers of sanctioned military components. The current strategic window will not stay open indefinitely, and every month of delay in strengthening Western sanctions grants the Kremlin an unwelcome reprieve. That is why this investigation closes with a clear call for vigilance and for accelerating support to Kyiv.

Every data point gathered here, from Bloomberg to the Kiel Institute, points toward the same conclusion: the refinery campaign is not a marginal irritant but a core pillar of Ukrainian strategy. The coming months will show whether Kyiv can sustain the tempo of these strikes while Western allies finally close the loopholes that keep feeding the Kremlin's war chest through third-country intermediaries and sanctioned shipping networks.

Columnist's transparency note

Who I am and my declared biases

I sign my texts under the name Maxime Marquette, columnist-analyst for mad-m.ca. I hold a declared pro-Western and pro-Ukrainian editorial line, critical of Russia, China, Iran, and North Korea. I consider Volodymyr Zelensky a courageous leader facing an unjustified aggression.

My method consists of cross-checking multiple reputable journalistic sources before stating a fact, and clearly separating my personal opinions, always in italics, from verified and sourced facts. I update my assessments whenever new reporting or new data emerges, rather than clinging to an earlier take for the sake of consistency.

What I don't know

I do not know with certainty the exact extent of the damage at the Yaroslavl site, for lack of complete official confirmation. Nor do I know how long Russia will take to repair its damaged facilities, or whether Chinese suppliers will be able to backfill every shortfall. I do not invent any testimony or anonymous source.
