**Deck**: Ukraine says nearly 40% of Russia’s primary oil refining capacity is now offline after a wave of strikes, just as senior Russian financial officials warn Putin that runaway defense spending could blow out the budget. As drones hit terminals in occupied Crimea and tankers burn, Moscow is being forced to fight a high‑tech energy war abroad while confronting a creeping fiscal rebellion at home.

Russia is being squeezed on two fronts it long treated as strengths: energy and money. Ukrainian officials now say almost 40% of Russia’s primary oil refining capacity was out of action in May after months of long‑range strikes, even as senior figures in Moscow’s finance and central bank circles privately warn Vladimir Putin that current war spending is destabilizing the budget.

On June 1, Ukrainian President Volodymyr Zelensky said that “nearly 40% of primary oil processing in Russia” had been knocked out as of May. His comments followed a string of Ukrainian deep‑strike operations, including an overnight May 30 attack by Ukraine’s 412th “Nemesis” Brigade on the Feodosia oil terminal in occupied Crimea, which reportedly hit two large tanks of oil products and triggered a major fire confirmed by follow‑up reconnaissance. Russian military bloggers have also reported Ukrainian‑made Hornet strike UAVs targeting fuel trucks near Dzhankoi in Crimea. In parallel, Western reporting indicates that senior Russian finance and central bank officials have cautioned Putin that the current pace of defense expenditure risks sharply widening the budget deficit and have proposed cuts in military spending.

For ordinary Russians, the war’s new front is visible not only on the battlefield but also at the pump and in public services. Damage to key refineries has already led Moscow to intermittently tighten fuel export controls to stabilize domestic supplies. If Zelensky’s numbers are roughly accurate, prolonged outages could squeeze domestic fuel availability in regional areas, drive up prices, and put additional strain on logistics in a vast country that depends on rail and road to move goods. On the Ukrainian side, every successful hit on an oil depot or terminal in occupied territory is presented as both revenge and relief: a way to limit the fuel feeding the missiles, glide bombs, and armored vehicles that are hitting Ukrainian cities and front‑line positions daily.

Strategically, the strikes are part of Kyiv’s deliberate effort to shift the costs of war deeper into Russia. By reaching hundreds of kilometers beyond the front line and targeting high‑value energy infrastructure, Ukraine is attempting to erode Russia’s ability to fund and fuel its campaign. Oil and gas revenues are central to the Kremlin’s war chest; forced refinery shutdowns threaten export volumes and premium product output, which can ripple through global markets and complicate Russia’s attempts to re‑route flows away from Europe. At the same time, the reports of internal warnings to Putin about defense spending show that, even within the elite, there is concern that a war‑driven fiscal expansion is pushing the state toward an unsustainable deficit.

That internal debate matters because Russia has so far insulated most of its population from the full financial cost of the war. Higher military salaries and defense orders have supported incomes in some regions, while tight capital controls and re‑directed trade have kept the system functioning. If technocrats are now pushing back, arguing that without curbing defense expenditure “Russia’s public finances will be difficult to stabilize,” it signals that the room for improvisation is shrinking. Any serious effort to cut war spending would clash with battlefield needs just as Russian forces intensify operations along multiple sectors in eastern Ukraine.

From Kyiv’s perspective, the pressure is intentional and time‑bound. Ukrainian military intelligence chief Kyrylo Budanov has said Ukraine has enough capabilities to try to end the “hot phase” of the war and that there are real signs of a foundation for halting active hostilities, even though Russia still has resources to continue fighting. He has also indicated that negotiation tracks are alive, if largely non‑public, and that envoys for Trump have confirmed a visit to Kyiv—an indication that Ukraine is calibrating military pressure with diplomatic options.

## Key Takeaways

- Zelensky says nearly 40% of Russia’s primary oil refining capacity was out of action as of May after Ukrainian strikes.
- Ukraine’s 412th Nemesis Brigade hit the Feodosia oil terminal in occupied Crimea on May 30, causing large fires, and Ukrainian drones have reportedly targeted fuel trucks near Dzhankoi.
- Senior Russian finance and central bank officials have privately warned Putin that current defense spending risks widening the budget deficit and urged cuts.
- Damage to Russian energy infrastructure threatens domestic fuel supply and export earnings central to funding the war.
- Ukraine sees deep strikes and financial pressure as tools to accelerate conditions for ending the “hot phase” of the conflict while keeping negotiation channels open.

## Outlook & Way Forward

In the near term, continued Ukrainian attacks on refineries, depots, and logistics hubs inside Russia and in occupied territory are likely, especially if they produce visible economic effects. Moscow will respond with layered air defenses, hardening of critical sites, and alternative routing of fuel supplies, but the sheer geography of Russia’s energy network offers Kyiv multiple points of pressure. Each successful hit increases the incentive for the Kremlin to lean on domestic refineries and cut export volumes, which can both stabilize local markets and erode foreign currency earnings.

Over the medium term, the collision between military needs and fiscal limits could become a quiet but decisive battlefield. If Putin rejects calls for defense cuts, Russia may be forced into a choice between deeper domestic austerity, higher inflation through monetary financing, or expanded borrowing that tests the patience of key elites. If he accepts some limits on spending, frontline commanders could face shortages in munitions, maintenance, and rotations that offer Ukraine tactical openings. Kyiv’s challenge will be to sustain pressure without triggering Western fatigue or giving Moscow room to paint the strikes as terrorism rather than targeted attacks on its war machine. Whether this dual campaign on oil and budgets shortens the war or pushes Russia toward a more entrenched militarized economy remains an open question—but the costs are becoming harder for Moscow to hide.
