With 84% of Russia's war budget classified, how reliable is SIPRI's spending data?
Latest on SIPRI
- What is SIPRI?
- SIPRI, the Stockholm International Peace Research Institute, is an independent Swedish policy institute founded in 1966. It produces authoritative annual data on global military expenditure, arms transfers, and arms control, widely used by governments and journalists as a neutral reference.Source: SIPRI
- What did SIPRI reveal about Russia's arms exports?
- SIPRI data released 9 March 2026 showed Russian arms exports fell 64% over the most recent five-year period. EU member states grew 36% over the same period, outpacing the US (27%) and China (11%).Source: SIPRI
- How much is Russia spending on defence in 2026?
- SIPRI analysis by Julian Cooper shows Russia allocated 16.8 trillion rubles to defence and security in 2026, representing 38-40% of all federal spending. Total military spending was estimated at $165.6 billion (5.8% of GDP), with 84% of the budget classified.Source: SIPRI / Julian Cooper
- How does SIPRI compare to official government defence statistics?
- SIPRI uses a consistent methodology across all countries, measuring actual expenditure rather than declared figures. This makes its estimates more comparable internationally but means they can diverge from official national statistics, particularly for states that classify most defence spending.Source: SIPRI
- Is SIPRI data reliable for Russian military spending?
- SIPRI acknowledges that 84% of Russia's military budget is classified, meaning its estimates rely on partial official data and observable procurement activity. The institute considers this a methodological limitation but produces figures treated as the most credible independent benchmark available.Source: SIPRI
Background
The Stockholm International Peace Research Institute (SIPRI) was founded in 1966 and is based in Solna, Sweden. It is an independent policy institute producing authoritative annual data on global military expenditure, arms transfers, and arms control. Governments, journalists, and international organisations treat SIPRI figures as the closest available neutral ledger in a field where every party has an interest in shaping the numbers.
SIPRI has been central to two major datasets in 2026. Its arms-transfer figures, released 9 March, showed Russia's arms exports fell 64% over the most recent five-year period, while EU member states grew 36%, outpacing the US at 27% and China at 11%. It also published Julian Cooper's analysis of Russia's 2026 federal budget, revealing defence and security consuming 38-40% of all federal spending, a Soviet-era ratio not seen since the USSR collapsed.
SIPRI's authority rests on methodological consistency across decades: it compares what states actually spend, not what they declare. With 84% of Russia's military budget classified, independent verification is near-impossible, which makes SIPRI's estimates both indispensable and contested.
