The 2024 polymer issue marks a material shift for Brunei's highest-circulation large denomination — the sultanate had issued paper substrate 100-dollar notes through most of the modern series before transitioning to polymer for enhanced durability in a tropical climate where humidity degrades paper currency rapidly. Brunei and Singapore maintain a Currency Interchangeability Agreement dating to 1967, meaning this note circulates at par acceptance in both countries, an arrangement that has outlasted most such bilateral currency pacts globally.
Pick 45 is among the earliest catalogue references assigned to Brunei's polymer transition for this denomination.
