Military Expenditure in Brunei, 1984-2022

Brunei's military expenditure displayed significant variation from 1984 to 2022, largely reflecting changes in oil revenues, the backbone of its economy. The 1980s witnessed high spending, peaking at 6.6% of GDP in 1988, aligning with efforts to bolster national security post-independence in 1984. The 1990s saw spending stabilize around 5–6%, reflecting Brunei's economic prosperity during this period.

After 2000, military expenditure began a gradual decline, dropping to 2.3% by 2008, paralleling global economic shifts and diversification efforts within Brunei. However, moderate increases followed in the 2010s, such as 3.6% in 2020, likely tied to regional security concerns. By 2022, spending decreased to 2.4%, reflecting a continued focus on balancing defense needs with fiscal sustainability.
