Russia's War Economy: A Flow Analysis of Stagnation and Fiscal Strain

The core economic reality is a collapse into near-zero growth. Russia's GDP expanded by 0.6% in real terms in the third quarter of 2025, marking the slowest pace since 2023 and a sharp deceleration from the 1.1% growth seen in the prior quarter. This stagnation is the direct result of a war economy consuming its own future. The two-year consumer boom, fueled by military-linked wage increases and state transfers, has now petered out, leaving household spending quashed by persistently high interest rates.

The mechanism is a self-consuming cycle. The economy entered a "war economy" where state spending on defense became the primary growth engine, generating temporary liquidity and wage growth. However, this growth was built on a foundation of military rent-budget transfers to defense enterprises that pay for assets designed for destruction. As former central bank adviser Alexandra Prokopenko noted, the economy is stuck in a "death zone," where holding itself together consumes future capacity faster than it can be rebuilt. The money that keeps factories humming pays for tanks and weapons that are eventually destroyed, offering no return on investment for future economic output.

This creates a fragile equilibrium. The system is not in imminent collapse, but it is not growing either. The central bank's rate cuts and fiscal measures to rein in the budget deficit cannot fix a structure that burns its own capital. The result is a stagnant, high-interest-rate economy trapped in a negative equilibrium, where the fuel is the destruction of its own productive capacity.

The Fiscal Drain

The state's financial buffer is being drained by a widening fiscal gap. Russia's consolidated budget deficit is projected to reach 8.3 trillion rubles, or 3.9% of GDP for 2025. This is a significant strain, with regional deficits far exceeding initial forecasts and ballooning to 1.54 trillion rubles due to war-related spending. The federal budget itself ran a record nominal deficit of 5.6 trillion rubles, or 2.6% of GDP.

The critical shift is a complete reliance on borrowing. For the first time, the government covered its entire fiscal gap through new bond sales, despite elevated interest rates. This move to finance the war through debt is a stark departure from past practice and directly increases future debt-servicing costs, which now consume a larger share of spending.

This borrowing spree has left the state's primary reserve nearly empty. The National Wellbeing Fund, a key rainy-day reserve, remains almost 60% below pre-war levels after three years of heavy drawdown. While it saw a modest 7% increase in 2025, this rebound is a temporary adjustment, not a trend. The fund's depleted state means the government has exhausted its liquid assets, forcing it to turn to the bond market to fund operations.

The Energy Revenue Collapse

The war economy's primary cash engine is now sputtering. In January 2026, Russia's fossil fuel export earnings fell to EUR 464 million per day, the lowest daily level since the invasion began. This represents a marginal 3% month-on-month decline, but the underlying pressure is severe. The state's tax take from oil and gas, the direct fiscal lifeline, collapsed from 587 billion rubles in December to just 393 billion rubles (€4.27 billion) in January. That's a drop of over 33% in a single month, pushing revenues to their lowest point since the pandemic.

The mechanism is a brutal squeeze on export value. The Urals crude discount to Brent widened to about $25 per barrel in December, directly eroding the profit margin on each barrel sold. This discount, combined with new sanctions and a crackdown on the "shadow fleet" of tankers, is forcing Russia to sell more oil at lower prices. The result is a sharp decline in revenue per barrel, which is now overwhelming any volume gains from buyers like China and India.

This collapse is a critical vulnerability. The state is already resorting to higher taxes and borrowing to fill the gap left by slower growth and dwindling oil revenues. With the National Wellbeing Fund depleted and the budget deficit ballooning, the government has no fiscal buffer to absorb this sustained drop in energy income. The war economy's ability to fund itself is being directly challenged by a shrinking cash flow from its most vital asset.
