In 2023, global military expenditure rose for the ninth consecutive year, exceeding $2.4 trillion. This surge, fueled by the ongoing Russia–Ukraine war and escalating geopolitical tensions, marked a 6.8% increase—the largest annual rise since 2009. This pushed world military spending to its highest level recorded by SIPRI (Stockholm International Peace Research Institute). The global military burden, defined as military expenditure as a share of GDP, reached 2.3%, with governments dedicating an average of 6.9% of their budgets to defence or approximately $306 per person.
