We refer to the recent forum letters from Mr Li Yong Si, Suggestion for $20 commemorative note to become normal circulation note /20 and Mr Luo Jie Sheng, Looking forward to the second issuance of Bicentennial commemorative notes (Lianhe Zaobao, 13 June 2019), and thank them for their suggestions.
The Monetary Authority of Singapore (MAS) announced on 14 June 2019 that it will issue an additional two million pieces of the Singapore Bicentennial $20 commemorative note to meet strong public interest. The additional notes will be ready around October to November this year. We will consider reintroducing the $20 denomination in a future note series.
