Which of these banks are NOT authorized to issue currency notes in Hong Kong?

OCBC, which stands for Oversea-Chinese Banking Corporation, is not authorized to issue currency notes in Hong Kong. This is because OCBC is a Singaporean-based bank and does not have the authority to issue currency notes in a jurisdiction outside of Singapore. In Hong Kong, the issuance of currency notes is managed by the Hong Kong Monetary Authority and only authorized banks are granted the privilege to issue currency notes in the region. Therefore, OCBC does not have the authorization to issue currency notes in Hong Kong.
