World military expenditure increased for the ninth consecutive year in 2023, reaching a total of $2443 billion. The 6.8 per cent increase in 2023 was the steepest year-on-year rise since 2009 and pushed global spending to the highest level SIPRI has ever recorded. The world military burden—defined as military spending as a percentage of global gross domestic product (GDP)—increased to 2.3 per cent in 2023. Average military expenditure as a share of government expenditure rose by 0.4 percentage points to 6.9 per cent in 2023 and world military spending per person was the highest since 1990, at $306. 

The rise in global military spending in 2023 can be attributed primarily to the ongoing war in Ukraine and escalating geopolitical tensions in Asia and Oceania and the Middle East. Military expenditure went up in all five geographical regions, with major spending increases recorded in Europe, Asia and Oceania and the Middle East.

This SIPRI Fact Sheet highlights trends in military expenditure for 2023 and over the decade 2014–23. The data, which replaces all military spending data previously published by SIPRI, comes from the updated SIPRI Military Expenditure Database.
