Russia’s oil and gas tax revenue rose by 32.4% year-on-year (YoY) in May to 678.9 billion roubles ($9.3 billion), supported by higher global oil prices amid escalating tensions in the Middle East, according to data released by the Russian Finance Ministry and cited by Reuters.

Revenue declined by 20.7% from April, when the federal budget benefited from additional profit-based tax payments that are collected periodically.

In the first five months of 2026, oil and gas revenue totaled nearly 3 trillion roubles, marking a decline of around 30% compared to the corresponding period in 2025.

Oil and gas income accounts for roughly one-fifth of Russia’s total budget revenue. The country’s 2026 budget projects oil and gas revenue at 8.92 trillion roubles, while total budget revenue is forecast to reach 40.283 trillion roubles.
