Ukrainian President Volodymyr Zelensky said that Russia’s oil refining has fallen by around 10% in recent months as a result of sustained pressure.

Axar.az reports that in a post on his official X account, Zelensky stated that Russian oil companies are being forced to shut down oil wells, which is contributing to broader economic strain.

He added that Russia’s overall state revenues are also under pressure, noting:

"As for Russia’s overall state revenues – thanks to our comprehensive pressure at all levels – within the first five months of this year, Russia’s deficit has already grown far beyond what it had planned for the entire year."

Zelensky also commented on Russia’s financial reserves, stating:

"Putin has, of course, built a war chest – but certainly not enough to fight indefinitely."

He concluded that continued coordinated pressure from Ukraine and its partners is having an impact:

"Every one of our responses, every joint step of pressure together with our partners, pushes Russia closer to ending its war."
