Ukraine’s long-range drone campaign against Russia’s oil industry in spring and summer 2026 is simultaneously hitting three sensitive areas of the country’s war economy: fuel production, domestic logistics of petroleum products, and fiscal stability. The attacks have not collapsed the oil sector as a whole and have not yet cut off Russia’s export revenues. What they have done is shift the structure of losses. Russia is increasingly forced to export crude oil instead of refining it domestically, forgoing part of the value added, facing regional fuel shortages, sharp rises in gasoline prices, accelerating inflation, and ever more expensive compensatory payments from the budget.
This is the strategic significance of the new phase of Ukraine’s campaign. While the earlier strikes were seen primarily as a demonstration of Ukrainian drone capabilities and the vulnerability of Russian military-industrial and energy facilities, the 2026 attacks reveal a more complex picture. Kyiv is now targeting not only export terminals and tank farms but also the parts of the oil value chain where damage produces a multiplier effect: primary distillation units, isomerization, cracking and hydrotreating facilities, as well as the nodes that supply fuel to Russia’s largest consumer regions.
“Double strike”: drones and sanctions
A particularly important milestone was the strikes on the Moscow Refinery in Kapotnya, one of Russia’s largest facilities with an annual capacity of around 11 million tons of crude. Russian oil infrastructure had already been hit before, but successful attacks on one of the key plants serving the capital region gave Ukraine’s campaign a new economic dimension. Moscow is not just Russia’s largest city; it is the country’s main consumer, transport, and administrative hub. Disruptions to fuel supplies in the capital therefore have far wider repercussions than the loss of equivalent capacity on the periphery.
The Moscow Refinery matters not only for its processing volume but also for its position in the fuel supply system. It provides a significant share of gasoline and diesel for Moscow and the Moscow region, which account for 14% of Russia’s passenger cars — 7.4 million out of 53 million nationwide. The plant is also tied to the needs of the Moscow aviation hub, through which roughly 40% of Russia’s passenger air traffic passes, and the region handles 19% of the country’s road freight.
A prolonged shutdown of this refinery would therefore create not only a production problem but a logistical one as well. Even if fuel can be sourced from other regions, it must still be delivered to specific locations at specific times through an already strained transport network that itself remains vulnerable to further strikes.
Russia’s oil sector had long been considered one of the most resilient parts of the economy. It weathered sanctions, the oil price cap, the EU embargo on seaborne crude and products, G7 restrictions, the departure of Western oil-service companies, the rerouting of trade flows, and dependence on a shadow tanker fleet. Strikes on refineries, however, exert a different kind of pressure. Sanctions reduce export margins and raise transaction costs. Drone attacks impair the physical ability to refine oil and supply the domestic market. This is no longer a question of a discount to Brent or freight rates — it is a question of the availability of gasoline, diesel, and jet fuel inside the country.
Industrial statistics confirm that these are not isolated glitches. In May 2026, production of coke and petroleum products in Russia fell 13.5% year-on-year. Over January-May the decline reached almost 5%. Refining volumes normally fluctuate due to maintenance, seasonality, and export conditions, but a drop of this magnitude against the backdrop of repeated attacks points to a systemic problem. Strikes intensified from late March; by April the year-on-year decline was already around 9%, and May marked the steepest fall in many years.
The core vulnerability of refineries lies in the fact that modern refining is far more than simple distillation. To produce gasoline and diesel meeting mass-market standards, plants require complex secondary processing units. Damage to these installations is much harder to repair than a fire in a storage tank. Repairs demand specialized materials, electronic components, pumps, compressors, catalysts, and engineering solutions — many of which were previously sourced from Western suppliers or produced domestically with their involvement.
Under sanctions, access to these components is severely restricted. Russian companies had previously been able to work around restrictions through parallel imports and technological adaptation. Now they must do so amid fires, emergency repairs, repeated strikes, and rising domestic demand. The result is a “double strike”: the drone inflicts physical damage, while the sanctions regime prolongs recovery times or makes repairs to certain units extremely difficult. What used to take weeks can now stretch into months because of circuitous supply routes, lower-quality substitutes, and emergency work without full manufacturer support.
The more frequently the same plants are hit, the greater the cumulative “fatigue” of the equipment. The Ryazan and Saratov refineries have each been struck 15 times. Units undergo emergency shutdowns and restarts, overheating, cooling, and off-design operation. This raises the risk of further failures even without direct hits. Consequently, the damage goes beyond visible fires and destroyed tanks: the attacks reduce the reliability of the entire refining system, making it less stable, less predictable, and more expensive to maintain.
Evolution of Ukraine’s strategy and its consequences
In the first phase of the 2026 campaign, many strikes targeted export-oriented port infrastructure — terminals, tank farms, and oil depots near Ust-Luga, Primorsk, Novorossiysk, and related facilities. These attacks produced dramatic visuals and immediate disruption: burning oil or products, halted loadings, tanker delays, and higher insurance and logistics costs. Their economic effectiveness, however, proved limited.
Tank farms are designed so that even a successful strike usually damages or destroys individual tanks rather than the entire facility. A terminal may temporarily lose part of its capacity, but as long as pipeline and rail connections remain intact and enough tanks survive, loadings can generally resume relatively quickly. After the strikes on Baltic and Black Sea ports, tanker exports initially dropped sharply but then recovered and in some cases even increased.
The subsequent rise in crude exports does not signal improvement for Russia. On the contrary, it is a symptom of the problem. When oil cannot be refined domestically, it is redirected to export to avoid cutting production or overloading storage. In the short term this helps fiscal stability: crude exports continue to generate foreign-currency revenue and support the tax base. But the structure of earnings deteriorates. Russia loses refining margins, higher-value-added product exports, and flexibility in domestic supply. Forced growth in crude exports allows partial volume compensation, but on less favorable terms — with discounts, higher logistics costs, dependence on a narrower circle of buyers, and added pressure on maritime infrastructure.
Ukraine’s shift from export infrastructure to refineries has therefore proved more effective. Refineries sit at the narrow point between crude production and the domestic fuel market. Knocking out part of refining capacity does not make the oil disappear, but it turns the oil itself into a problem: it can be exported, yet domestic supply of gasoline, diesel, and jet fuel falls. Crude can be redirected to other plants, but not all refineries can absorb extra volumes, not all produce the required product slate, and moving products to deficit regions places additional strain on railways and pipelines.
This has already shown up in the fuel market. In June, Russian regions began imposing sales restrictions: per-person purchase limits, bans on filling jerry cans, and priority supply for municipal services, farmers, public transport, and emergency responders. Authorities usually cite “panic buying” or “logistical difficulties,” but the geography of the restrictions reveals a systemic issue. They have appeared simultaneously in central Russia, the south, the Volga region, Siberia, and the Far East. The fuel crisis has now affected 83 regions and continues to spread.
Prices are also reacting faster than usual. In the second half of June, Rosstat recorded sharp weekly increases in gasoline prices (+3.0% and +1.6%) and diesel (+2.7% and +2.2%) nationwide. Gasoline price changes were registered in 82 regions, with the sharpest rise in annexed Sevastopol (+30%). This is particularly sensitive in Russia, where the state has spent years trying to hold down retail fuel prices through the damper mechanism, export restrictions, and informal agreements with oil companies. Fuel in Russia is not merely a market commodity; it is a politically charged price that influences inflation expectations, logistics, agriculture, transport costs, and perceptions of stability.
Higher gasoline prices generate secondary effects. Goods transportation becomes more expensive, farmers’ costs rise, small businesses face higher expenses, and delivery, construction materials, and food prices increase. Even though fuel represents a limited share of the consumer basket, gasoline has a powerful psychological impact: drivers see the price every day, and queues at filling stations become a visible sign of shortage. A fuel crisis therefore quickly turns from a sectoral problem into a macroeconomic one.
The Bank of Russia has taken note. Its decision on 19 June to cut the key rate by only 25 basis points (to 14.25%) reflects regulatory caution: rising fuel prices are amplifying pro-inflationary risks and limiting the scope for monetary easing. The stronger the fuel-driven price and expectation pressures, the longer the central bank must keep rates high, the more expensive credit becomes, the higher the cost of servicing debt, and the weaker investment activity outside the military sector.
Budgetary effects
The impact of Ukrainian strikes on Russia’s budget operates through several channels. The first is the direct reduction of the tax base in refining. Lower fuel output means the state receives less revenue from production- and sales-linked taxes — primarily excise duties, but also VAT, profit tax, and related payments. Precise quantification is difficult, but indirect estimates illustrate the scale. Already at the beginning of the year, direct losses to the oil sector from the attacks were estimated at more than 100 billion rubles; including lost profits and indirect losses, the figure exceeded 1 trillion rubles.
The Moscow Refinery offers a useful illustration. In 2024 it produced 2.9 million tons of gasoline and 3.2 million tons of diesel. At 2026 excise rates — 17,959 rubles per ton for Euro-5 gasoline and 12,738 rubles per ton for diesel — the refinery’s half-year output of these products would correspond to roughly 46 billion rubles in potential excise revenue. This does not mean the budget automatically loses the entire amount, but it shows the order of magnitude of the direct fiscal risk from a prolonged shutdown of a single large plant — before even accounting for VAT, profit tax, repair costs, and wider losses across the refining sector.
The second channel is the rise in spending to stabilize the domestic market. The scale is already visible in direct budgetary transfers to oil companies. In April-June alone, amid the refinery strikes and falling utilization, oil companies received approximately 1.03 trillion rubles through the damper mechanism and reverse excise. These payments cannot be attributed entirely to the strikes, as they also depend on global prices, the ruble exchange rate, and the tax formula. Nevertheless, they demonstrate that problems in refining are turning the oil sector from a source of budgetary rent into an object of growing budgetary support.
The Russian government has already been forced to adjust tax rules, allow the release of lower-grade fuel, extend tax benefits for refineries that delay modernization, import certain volumes of fuel, restrict product exports, and redirect supplies to priority regions. All of this means the budget is not only losing revenue but also assuming additional obligations. The deeper the fuel deficit, the more the state must pay to keep domestic prices below market levels.
The third channel is regional. The fuel crisis compels regional authorities to intervene, organize manual supply arrangements, and support transport, utilities, and agriculture. This adds to the burden on regional budgets at a time when their overall position is already deteriorating: in the first quarter of 2026 the number of regions running budget deficits reached 56, up from 46 a year earlier. Fuel disruptions are therefore becoming not only a sectoral but an inter-budgetary problem: the center may be forced to compensate regions for extra spending or assume greater direct control over supply allocation.
The broader budgetary context is that Russia entered this campaign with an already weakening fiscal position. The 2026 federal budget was drawn up on assumptions of a weaker ruble and a certain level of oil-and-gas revenues. In the first months of the year, however, the ruble proved stronger than expected while oil-and-gas receipts lagged significantly behind 2025 levels — remaining roughly 30% lower year-on-year through January-May. The federal budget deficit for the first five months already exceeded 6 trillion rubles, or 2.6% of GDP, surpassing the planned annual deficit. At the same time, total arrears owed to the budget by citizens and companies reached nearly 4 trillion rubles in the first quarter.
The Accounts Chamber estimated a possible revenue shortfall for 2026 of around 2.1 trillion rubles, including more than 1 trillion rubles in oil-and-gas revenues. These projections may prove optimistic. They reflect already visible deviations but do not yet incorporate the risk of further attacks in the second half of the year and likely do not factor in the expiration of U.S. sanctions relief for Russian oil (the relevant general license lapsed on 17 June). Peak fuel demand occurs in summer and early autumn — the holiday season, harvest campaign, construction activity, and freight movements. If damaged refineries are not restored quickly, the government will face a choice among three unattractive options: allow further price increases (worsening inflation), intensify administrative rationing, or expand subsidies and fuel imports.
Each option carries a cost. Market-driven price rises would curb demand but hit households and inflation. Administrative allocation would create queues, shortages, and black markets. Subsidies and imports would help stabilize supply but would increase budgetary outlays and produce the absurd situation of one of the world’s largest oil powers having to buy fuel abroad or subsidize its own oil companies because domestic refining capacity is offline.
It is important not to overstate the effect. Russia’s oil sector is not broken. Crude production continues, raw-oil exports are maintained, the shadow tanker fleet operates, Asian buyers continue purchasing Russian oil, and the state retains significant administrative tools to reallocate resources. Maintaining this “resilience,” however, is becoming steadily more expensive, and room for maneuver is narrowing. Strikes on refineries target precisely the state’s ability to balance war requirements, domestic prices, budgetary commitments, and social stability. They do not necessarily trigger an immediate crisis, but they raise the cost of every additional month of war.
The price of manageability
The main risk for Russia is not a complete shutdown of the oil sector — that scenario remains unlikely for now — but the shift of refining into a state of chronic instability. In this scenario, refineries start up and shut down repeatedly; gasoline and diesel output becomes volatile; regions operate in permanent “firefighting” mode; temporary sales restrictions become recurring practice; queues at filling stations turn into a normal feature of daily life; budgets spend more on compensation; and refining volumes remain below normal levels.
In this context, the financial consequences of the strikes cannot be measured solely by the value of burned tanks or lost excise revenue. The real price is the combined effect of direct losses, foregone margins, compensatory payments, logistics costs, inflationary pressure, tighter monetary policy, and deteriorating fiscal indicators. Individually, each channel may appear manageable. Together, they exert pressure on one of the key pillars of Russia’s war economy.
If oil prices remain high, Russia can partially offset these losses. But the offset will become progressively less sustainable. Should oil market conditions deteriorate, new sanctions bite, pressure on refineries continues, and the need for subsidies grows, the budget deficit could exceed expectations. The problem is not limited to public finances. Against a backdrop of high interest rates, rising costs, and weakening demand, nearly a quarter of Russian enterprises have reported a deterioration in their financial position.
In this sense, Ukraine’s campaign against Russia’s oil industry has moved the war into a new economic dimension. Oil continues to generate revenue, but refining has become a weak link. Crude exports may rise, yet the domestic fuel market contracts. The government retains control, but it is forced to pay an ever-higher price for that control.
For Russia this is a dangerous combination. A war economy can function for a long time under sanctions, shortages, and heavy-handed management — provided the population does not feel the direct effects of the war in everyday life. A fuel crisis changes that perception and makes the war visible inside Russia. Strikes on refineries therefore carry not only economic but also political weight. They demonstrate that Russia’s strategic depth is no longer safe and that oil rent is no longer insulated from direct military pressure, becoming a less reliable foundation for the budget and social stability. The longer the attacks on refining capacity continue, the more Russia is forced to spend not on development but simply on keeping the sector operational.
