Impact of Supply-Side Inflation on Military Expenditures Across World Regions During 2019–2023

This paper examines the phenomenon of supply-driven inflation within military expenditures across various global regions from 2019 to 2023. As nations face escalating geopolitical tensions and security challenges, understanding the inflationary pressures on defence budgets becomes increasingly vital. This study identifies key factors contributing to inflation in military spending, including increased costs of raw materials and technological advancements in defence systems. Utilizing comprehensive data from the Stockholm International Peace Research Institute (SIPRI), the research employs a statistical method and time series analysis to assess variations in military expenditure inflation rates across world regions such as the Americas, Europe, Africa, Asia and Oceania, and the Middle East, and to predict future trends in military expenditures. Through this analysis, regional disparities will be uncovered in inflationary trends while the impact of currency fluctuations and policy decisions on defence budgets will be highlighted.
