Answer: Oman
Notes: Oman introduced its first polymer one-rial banknote, to start circulation on 11 January 2026. It is issued by the Central Bank of Oman, replacing traditional cotton-based notes with durable polymer for longer life and better security. The note size is 145 × 76 mm and showcases Oman’s cultural and economic identity. Front side features the Oman Botanic Garden, symbolising commitment to natural heritage. Rear side shows Sayyid Tariq bin Taimur Cultural Complex, Duqm Port and Refinery, highlighting cultural and economic progress. The polymer notes will circulate alongside existing one-rial notes and remain legal tender.
