Why is Russia's oil windfall unlikely to revive its slowing wartime economy?

The oil windfall—driven by Middle East tensions and higher global prices—is boosting export income but unlikely to spur growth because massive fiscal spending is inflating demand without increasing supply, as resources are diverted to military production; using the windfall for further spending would worsen inflation and justify the central bank maintaining high borrowing costs (currently 15% nominal, over 9% real), which stifle businesses; meanwhile, GDP likely contracted in Q1 2024—the first quarterly decline since early 2023—and the business climate index turned negative for the first time since 2022.

How does Russia's current fiscal rule limit the economic impact of rising oil revenues?

Under Russia’s fiscal rule, all oil revenue above the $59-per-barrel baseline is channeled into the National Wellbeing Fund, and the 2026 budget law explicitly prohibits using that fund to finance the deficit—meaning the windfall cannot be spent directly on stimulus or subsidies; additionally, the government is holding its oil price assumption steady at $59/barrel in its updated macroforecast despite higher market prices, while projecting a stronger ruble, implying lower actual oil-related budget proceeds than assumed.
