HKEX (00388.HK) will introduce a digital payment option on Dec 14 to allow prepaid margin payments for the derivatives post-close trading session, under a collaboration with the Hong Kong Monetary Authority to trial a digital Hong Kong dollar. Eligible clearing participants of the Hong Kong Futures Clearing Corporation may opt to submit prepaid margin requests via the digital channel between 17:00 and 01:30 so those funds are available for the post-close session. The extended window supplements existing payment arrangements, letting participants manage capital-based position limits outside normal banking hours.
