100 Brunei Dollars

As part of the 2026 GUARDIAN™ polymer series, the 100 Brunei Dollar note features Sultan Hassanal Bolkiah alongside the kuduk-kuduk (Melastoma malabathricum), known as Singapore rhododendron, with striking blue-purple blooms that hold medicinal significance in traditional Southeast Asian medicine. The Jame' Asr Hassanil Bolkiah mosque appears again on this denomination as a unifying design element, emphasizing Brunei's Islamic foundation. GUARDIAN™ polymer substrate provides exceptional durability for this high-circulation note, with advanced anti-counterfeiting measures including optically variable inks and sophisticated window features. DOMINO™ tactile embossed marks in a unique multi-dot arrangement specific to the 100 denomination assist visually impaired users.
