The Brunei 20 Dollar 2007 “40 Years Currency Interchangeability Agreement between Singapore and Brunei” Commemorative Note
In 2007, the Monetary Authority of Singapore (MAS) and Autoriti Monetari Brunei Darussalam (AMBD) issued a special 20-dollar commemorative banknote to mark the 40th anniversary of the Currency Interchangeability Agreement (CIA) between Brunei and Singapore (1967-2007). This agreement, signed in 1967, ensures that the Brunei dollar (BND) and Singapore dollar (SGD) are interchangeable at par value in both countries, reflecting a strong economic and diplomatic relationship.
This commemorative issue was released jointly by both nations, with similar designs but different national emblems—one for Brunei and the other for Singapore. The Brunei version carries Bruneian national symbols, while the Singapore version features Singaporean elements.
Overview of the Front and Back Note
The obverse (front) side of the banknote features a portrait of Sultan Omar Ali Saifuddien III, the 28th Sultan of Brunei and the architect of modern Brunei. Behind him, the national flower of Brunei, Simpor (Dillenia suffruticosa), is depicted, symbolizing prosperity and national pride. The background includes intricate security patterns and motifs that enhance the visual elegance and authenticity of the note.
The reverse (back) side of the banknote showcases landmarks from both Brunei and Singapore, symbolizing the economic and diplomatic ties between the two nations. Brunei’s Omar Ali Saifuddien Mosque and Singapore’s iconic skyline, including Marina Bay, the Esplanade, and the Parliament House, are beautifully illustrated. The text “40 Years of Currency Interchangeability Agreement” is displayed in the center, reinforcing the significance of this milestone.
