Hong Kong Exchanges and Clearing Limited (HKEX) published a consultation conclusion on optimizing the board lot framework for securities trading in the Hong Kong market on July 2, following consultation that received 85 responses from IPO and secondary market participants. The optimization aims to lower market entry barriers by reducing the minimum board lot value guideline from HKD 2,000 to HKD 1,000, introducing a HKD 50,000 upper limit for issuers with board lots exceeding 100 shares, and standardizing board lot sizes to eight designated options: 1, 50, 100, 500, 1,000, 2,000, 5,000, and 10,000 shares per lot. The framework applies to equities and real estate investment trusts (REITs) and will be implemented in two phases starting July 2 and November 16, 2026, as part of Hong Kong's broader market infrastructure enhancement to maintain its position as a leading international financial center.
HKEX Introduces Eight Standardized Board Lot Sizes and Revised Value Thresholds
HKEX decided to implement optimization measures for the board lot framework applicable to securities including stocks and REITs. The minimum board lot value guideline will be reduced from HKD 2,000 to HKD 1,000. For issuers with board lot sizes exceeding 100 shares, HKEX introduced a new upper limit of HKD 50,000 for board lot value. The standardized board lot sizes are limited to eight designated options: 1 share, 50 shares, 100 shares, 500 shares, 1,000 shares, 2,000 shares, 5,000 shares, and 10,000 shares per lot.
Two-Phase Implementation Timeline Starting July 2 and November 16, 2026
To facilitate a smooth market transition, HKEX will implement the adjustments in two phases. Phase one takes effect on July 2. Potential issuers submitting IPO applications before July 2 must comply with the new upper and lower board lot value guidelines. Potential issuers submitting IPO applications on or after July 2 must comply with all requirements of the new board lot framework. Existing issuers must comply with the new upper and lower board lot value guidelines. If existing issuers conduct corporate actions involving changes to board lot size, share consolidation, or share split, they must comply with all requirements of the new board lot framework.
Phase two takes effect on November 16, 2026, when the scripless securities market launches. All issuers must adopt one of the standardized board lot sizes within six months of completing the transition to the scripless securities market. For issuers that have completed the transition to the scripless securities market, changing board lot sizes will not require parallel trading.
HKEX Plans Automated Odd Lot Trading Mechanism for Q3 2027
In addition to optimizing the board lot framework, HKEX plans to optimize the odd lot trading mechanism and is studying the introduction of a new automated matching trading mechanism. Subject to regulatory approval and market readiness, HKEX is considering launching the mechanism as early as Q3 2027.
HKEX Market Head 余學勤 Comments on Framework Optimization
HKEX Head of Markets 余學勤 stated that implementing the simplified board lot framework is an important step for Hong Kong Exchanges and Clearing Limited to lower market barriers and facilitate investor participation in stock trading. He expressed satisfaction with the broad market support for these arrangements that help optimize market mechanisms and enhance trading efficiency. Standardizing board lot sizes will lay a solid foundation for continuous improvement of market microstructure and pave the way for future consideration of unified board lot sizes. This reform, combined with other market infrastructure optimization measures and product innovation, will further consolidate Hong Kong's position as a leading international financial center.
