The Brunei Darussalam and Singapore $50 polymer notes feature the same design elements and layout and are predominantly gold in colour to signify the golden jubilee of the Currency Interchangeability Agreement between Brunei Darussalam and Singapore.
The 50th Anniversary logo of the Currency Interchangeability Agreement is a key feature on the front of the note. It shows a unifying flower motif comprising the Simpur and the Vanda Miss Joaquim in full bloom. A unique element in the note is the see-through, colour-shifting window security feature that depicts Brunei Darussalam's Istana Nurul Iman and Singapore's Istana. A portrait of His Majesty Sultan and Yang Di-Pertuan of Brunei Darussalam is shown on the Brunei Darussalam note.
While the Singapore note features a portrait of Singapore's first President, Mr Yusof bin Ishak.
The back design of the note portrays the close collaboration between Brunei Darussalam and Singapore depicted by military personnel from the Royal Brunei Armed Forces and the Singapore Armed Forces in the areas of defence. Collaboration in education is represented by students from both countries engaging in cross-cultural learning and exchange of ideas.
