Russia spends 38% of budget on war

SIPRI data shows Moscow directing 38–40 per cent of federal spending to defence — a share not seen since the Soviet Union — while its fiscal reserves drain toward zero.

Key takeaway

Russia's defence budget has reached Soviet-era proportions, consuming fiscal reserves that cannot be rebuilt during wartime.

Professor Julian Cooper's analysis, published by SIPRI, puts Russia's 2026 defence and security allocation at 16.8 trillion rubles — 38 to 40 per cent of all federal spending 1. Army and weapons procurement alone accounts for 12.93 trillion rubles, the largest single budget category since the USSR. Total military expenditure reaches $165.6 billion, or 5.8 per cent of GDP, with 84 per cent classified — meaning independent verification of the actual spending breakdown is impossible 2.

The share-of-budget figure requires a specific comparison. The late Soviet Union devoted an estimated 15 to 25 per cent of GDP to defence (CIA and DIA estimates diverged throughout the Cold War), but it ran a command economy where the state controlled all output. Russia must sustain a wartime budget inside a market economy, and the seams are visible. The National Wealth Fund has been drained to historic lows. The budget deficit stands at 3.78 trillion rubles (1.6 per cent of GDP) — manageable by international standards, but running in one direction. Oil and gas revenues fell roughly 32 per cent year-on-year in January, with Urals Crude below $38 per barrel against Brent at $62.50 . Russian arms exports have simultaneously collapsed by 64 per cent over the most recent five-year measurement period , confirming that domestic military-industrial output is being consumed internally rather than generating export revenue.

Cooper's assessment is direct: economic pressure "is unlikely to stop the war in Ukraine" 3. One variable supports that judgement. SIPRI notes the Iran conflict may improve Russia's fiscal outlook through higher energy prices — consistent with the €510 million in daily fossil fuel revenue recorded during the conflict's first fortnight , a 14 per cent jump above February's average. The Treasury's 12 March waivers on 124 million barrels of Russian oil provide additional relief on the revenue side .

The budget tells a clear story about priorities: Moscow has chosen guns over everything else. What it cannot reveal is the breaking point. Russia's Central Bank has used aggressive interest rate policy to contain the inflationary pressure that wartime spending generates, but 38–40 per cent of federal spending directed to a single purpose leaves minimal flexibility for civilian infrastructure, social spending, or responding to economic shocks. The National Wealth Fund was built from two decades of oil revenue precisely to absorb those shocks. It is now nearly gone. Russia is running a wartime economy without a safety net — sustainable as long as the war goes well and energy prices hold, catastrophically exposed if either variable turns.

Deep Analysis

In plain English

Russia is spending nearly 40 pence of every government pound on its military — a level not seen since the Soviet Union. Its emergency savings fund (the National Wealth Fund) is nearly empty after years of drawdowns. The government is running a deficit, meaning it is borrowing to sustain both the war and civilian obligations. When savings run out and borrowing costs rise, governments face stark choices: cut social spending, raise taxes, or inflate the currency. Russia is approaching that decision point, with no buffer remaining.

Deep Analysis
Synthesis

Russia's fiscal parameters — NWF depleted, Soviet-era budget proportion, growing deficit — represent a historically rare window of maximum Western economic leverage. That window has an uncertain duration: the Iran conflict's energy revenue bonus could extend Russian fiscal runway by 12–18 months. The simultaneous US enforcement dismantling (Event 11) means this leverage window may close unused, with no equivalent pressure point available once the NWF is fully exhausted.

Root Causes

The 84% classification rate of Russia's military budget is not merely strategic opacity — it reflects the deep integration of defence production into nominally civilian state enterprises (Rostec subsidiaries, regional military-industrial plants) that obscure the true economic mobilisation footprint. This structural opacity means external analysts systematically underestimate actual defence expenditure and cannot accurately calibrate the fiscal breaking point.

What could happen next?
  • Consequence

    Defence spending at 38–40% of federal expenditure is crowding out civilian healthcare and infrastructure investment, degrading Russia's human capital base over a multi-year horizon.

    Long term · Assessed
  • Risk

    An oil price correction — from Iran conflict resolution or global demand weakness — would hit the federal budget directly with no NWF buffer remaining to absorb the shock.

    Medium term · Assessed
  • Risk

    Iran conflict energy price inflation may extend Russia's fiscal runway by 12–18 months, frustrating Western assumptions about economic pressure as a war-termination mechanism.

    Short term · Suggested
  • Meaning

    The 84% classification rate prevents accurate external assessment of Russian fiscal durability, introducing irreducible uncertainty into any war-termination timeline estimate.

Causes and effects
This Event
Russia spends 38% of budget on war
The budget reveals a strategic bet: Russia is wagering the war ends before its fiscal position becomes untenable. The National Wealth Fund's depletion removes Moscow's primary shock absorber. If energy prices fall or the Iran conflict ends — removing the oil windfall — there is no reserve left to cushion the gap between wartime expenditure and peacetime revenue.
Different Perspectives
Turkey (Shakarab consideration)
Turkey (Shakarab consideration)
Ankara serves as one of two Western-adjacent Iran back-channels while Turkish national Gholamreza Khani Shakarab faces imminent execution on espionage charges in Iran. President Erdogan cannot deflect the domestic political crisis that a Turkish execution would trigger, which would force suspension of the mediating role.
Germany (Bundestag gap)
Germany (Bundestag gap)
Belgium, Germany, Australia, and France committed Hormuz coalition hardware on 18 May. Germany's Bundestag authorisation for the coalition deployment remains pending, creating a constitutional gap between the commitment announced and the parliamentary mandate required to operationalise it.

The IEA's $106 May Brent projection met the market in one session on 20 May as Brent fell 5.16% on diplomatic optimism. Goldman Sachs and Morgan Stanley's two-layer premium framework holds: the kinetic component compressed; the structural insurance component tied to Lloyd's ROE remains unresolved.

Hull rates stand at 110-125% of vessel value on the secondary market; the Joint War Committee has conditioned cover reopening on written ROE from the coalition or PGSA. The Majlis rial bill makes any compliant ROE structurally impossible to draft while the PGSA's yuan portal remains its operational mechanism.

The 26-nation coalition paper requires Lloyd's to see written rules of engagement before Hormuz war-risk cover reopens. The Majlis rial bill adds a second governance incompatibility on top of the unpublished PGSA fee schedule; coalition ROE cannot mention rial without conceding Iranian sovereignty over the strait.
