Hong Kong Exchanges and Clearing (HKEX) will move ahead with changes to its board lot framework after receiving broad support from market participants during a public consultation.
The exchange will standardize board lot units into eight options: 1, 50, 100, 500, 1,000, 2,000, 5,000, and 10,000 shares. It will also lower the minimum board lot value guidance from HK$2,000 to HK$1,000 and introduce a HK$50,000 ceiling for securities with board lots larger than 100 shares.
The new framework will be introduced in two phases, with the first taking effect on July 2, 2026. The second phase will begin on November 16, 2026, alongside the launch of Hong Kong’s Uncertificated Securities Market (USM).
Under the revised rules, new listings and certain existing issuers undertaking corporate actions will be required to comply with the standardized board lot structure. Existing issuers will also be subject to the updated value guidance, with HKEX conducting regular reviews of board lot values.
Separately, HKEX said it plans to enhance odd lot trading by introducing an automatic matching mechanism, with the new service expected to launch no earlier than the third quarter of 2027, subject to regulatory approval and market readiness.
Board lots represent the minimum number of shares that can be traded in a single transaction on the Hong Kong Stock Exchange. HKEX said the changes are intended to simplify trading arrangements and improve market accessibility as part of its broader market infrastructure modernization program.
