Russia's oil and gas receipts in the federal budget were about 5.02 tln rubles
(~$58.4bn at 86 rub/$) in Jan–Aug, down 16.7% YoY, the finance ministry said in
preliminary budget execution estimates on Sept. 9. The ministry cited a drop in
the dollar exchange rate and weaker oil prices in Q4 2025 and Q1 2026 as key
drivers. It said it would use the National Wealth Fund to plug the shortfall and
accumulate extra receipts during favourable price periods to stabilise the
budget amid oil‑and‑gas revenue volatility. Total federal budget revenue was
about 25.93 tln rubles, up 9.2% YoY, with non‑oil‑and‑gas revenue roughly 20.91
tln rubles, up 18.1%.
