HKEX announced the optimization of customer margin requirements to further enhance the efficiency of the derivatives market.

On June 22, Hong Kong Exchanges and Clearing Limited (HKEX) announced the optimization of its derivatives clearing house's customer margin requirements to enhance capital efficiency, reduce financing costs for market participants, and support the long-term development of the Hong Kong derivatives market. The revised customer margin requirements will also bring Hong Kong's margin multiples closer to other major international markets, promoting the continual growth of the Hong Kong derivatives market. Under the revised arrangements, customer margin multiples and customer maintenance margin requirements will be adjusted in two phases to allow the market to prepare adequately for and smoothly transition to the changes. The first phase is planned to be implemented on September 21, 2026, with the second phase expected to be implemented in March 2027 following regulatory approval. Currently, customer initial margin requirements are determined based on the clearing house's margin levels. The table summarizes the current arrangement and the adjustments made in stages after the revision. The phased implementation of the measures will facilitate an orderly transition for the market, enabling market participants to gradually adjust their systems and risk management arrangements while maintaining market stability. Participants may still charge customers higher margins based on their risk profiles, product characteristics, and current market conditions. These optimization measures also support HKEX's ongoing efforts to strengthen and expand its derivatives ecosystem to meet the evolving needs of investors and risk managers. Looking ahead, HKEX will continue to enhance market infrastructure and settlement arrangements, support product innovation, and enhance the capital allocation efficiency of the derivatives market. HKEX's Chief Operating Officer, Li Bo Yin, stated, "We are pleased to introduce these adjustments to customer margin requirements. This is the latest initiative from HKEX to continuously optimize market microstructure, enhance the vibrancy, resilience, and competitiveness of the Hong Kong market. Together with the previous optimization measures for margin collateral arrangements, this adjustment will further improve the efficiency of collateral use under careful risk control, promote more effective fund utilization, reduce costs, and enable market participants to manage hedging, trading, and investment portfolio activities more flexibly, further solidifying Hong Kong's position as an international risk management center."
