Global Central Government Expenditures on Defence by Country

In 2023, Israel led global defense expenditures relative to central government expenditure at 14.91%, despite declining by 1.39%. The United States followed at 13.62%, decreasing by 0.93%, and South Korea at 13.04%, falling by 0.26%. Germany and Australia saw moderate increases to 9.45% and 8.96% respectively. Estonia and Romania showed significant year-over-year increases by 1.82% each. In contrast, notable decreases were observed in Portugal (-3.52%), Ireland (-2.14%), and significant growth in Iceland at 29.67%. Despite minor reductions, Israel and the United States remained leaders in defense spending proportionate to their central government expenditures.

Future trends to watch include potential increases in European nations like Germany and the Baltic states responding to geopolitical tensions, sustained high spending by the United States and Israel, and potential adjustments in defense budgets among smaller nations like Iceland and Ireland, which showed significant year-on-year percentage variations. Monitoring emerging military needs and budgetary constraints will be critical.
