1 Dollar

Brunei's switch to polymer for small denominations has been incremental rather than wholesale — the 1 Dollar was among the first to make the transition, reflecting a broader regional trend accelerated by neighboring Singapore's own polymer adoption. The Autoriti Monetari Brunei Darussalam, established in 2011 to absorb the functions of the old Brunei Currency and Monetary Board, issues under the long-standing Currency Interchangeability Agreement with Singapore, meaning this note circulates at par with its Singaporean equivalent by treaty obligation.

The 2024 date places this among the earliest polymer issues under AMBD's current series framework. Polymer substrate from this period typically originates from Innovia or equivalent suppliers, though Brunei has not publicly confirmed its polymer source for this run.
