Share of World GDP: Brunei Darussalam

Analysis# Brunei Darussalam Share of World GDP Brunei Darussalam currently accounts for 0.021% of global GDP in 2026, reflecting a significant contraction from its all-time peak of 0.049% in 1985. Over four decades, the nation's share has declined 57.1%, marking a substantial loss of economic prominence on the world stage. This figure matches the all-time low recorded in 2017, indicating the country has failed to recover its previous economic weight despite intervening years of growth. The critical turning point occurred during the 1980s oil boom, when petroleum revenues propelled Brunei to its peak share. The subsequent decline reflects the vulnerability of a hydrocarbon-dependent economy as global energy markets shifted and production constraints emerged. Recent data from 2017 onwards shows stabilization around 0.021%, with minor fluctuations between 2018 and 2021 unable to sustain momentum. Projections through 2026 suggest this plateau will persist absent significant economic diversification.
