HKEX Enhances Client Margin Framework to Strengthen Derivatives Market Efficiency

HKEX announced on 22 June 2026 that it will lower derivatives client margin multipliers and maintenance margins in two phases (September 2026 and March 2026 pending regulatory approval) to align with major global markets. While keeping strict risk controls, the new rules boost capital efficiency and cut financing costs for market players, helping them conduct hedging and portfolio management. Firms may still set higher margins based on client and product risks. This upgrade improves market infrastructure and strengthens Hong Kong’s role as an international risk management hub. Full details are in circulars released by HKEX’s subsidiaries. Source: https://www.hkex.com.hk/News/Market-Communications/2026/260622news?sc_lang=en
