How the 2026 figures are produced. Neither figure is a researched budget estimate. The share-of-GDP figure is the arithmetic mean of Brunei’s last 3 reported years (2022–2024), carried across both estimate years unchanged. The dollar figure is not a per-country forecast — it is the actual SIPRI figure for 2024 raised by a flat 3%, the same rate applied to every country in this group, so it can rise even where the share-of-GDP path falls. Actual SIPRI figures for Brunei run to 2024.
