The new series of Hong Kong banknotes go into circulation from October 11, in denominations of $20, $50 and $1,000.

They will be available for exchange in all branches of the three note-issuing banks - the Bank of China (HK), Standard Chartered Bank (HK) and HSBC.

The first two denominations of the new series, $100 and $500, have been in circulation since December. All existing banknotes will continue to be legal tender and will circulate alongside the new banknotes.

Leaflets explaining and illustrating security features of the new banknotes are being distributed and posters are on display at the three note-issuing banks and the Monetary Authority.

Information is also available on the websites of the Monetary Authority, Bank of China (HK), Standard Chartered Bank (HK) and HSBC.

To promote public awareness on the security features of the new banknotes, the authority has been conducting seminars, along with a student ambassador programme covering around 40,000 retailers in markets, shopping centres and neighbourhoods.
