The Hong Kong Exchanges and Clearing (HKEX) proposed to implement T+1 in the fourth quarter of 2027 and consult the market for four weeks

The Hong Kong Exchanges and Clearing (HKEX) published a consultation document proposing to shorten the settlement cycle of the Hong Kong stock spot market from the current T+2 to T+1. It suggests adjusting multiple processes in the stock spot market, with a transition to the T+1 settlement cycle planned for the fourth quarter of 2027. The consultation period lasts four weeks and will end on May 18. T+1 Applies to Stocks and Options IPOs and Shanghai-Shenzhen Stock Connect Remains Unchanged The consultation document states that the proposed T+1 settlement cycle will apply to exchange trading in the secondary market, including stocks, exchange-traded products, structured products, and debt securities, as well as physical delivery of stocks after the exercise and transfer of stock options. Initial public offerings (IPOs) and transactions conducted through the Shanghai-Shenzhen Stock Connect will continue to follow the existing settlement timetable. HKEX Advocates Industry Review of Fund Allocation Procedures The document indicates that after adopting the T+1 settlement cycle, several other trading-related processes and market activities will need to be adjusted. HKEX is also consulting market opinions on the related adjustment arrangements. Additionally, HKEX recommends that market participants review their procedures related to securities and fund allocation, including securities lending, fund, and foreign exchange arrangements, to align with the proposed T+1 settlement cycle operational model. HKEX stated that it will release relevant technical specifications in due course to assist market participants in making necessary system upgrades. Once the market is ready and regulatory approval is obtained, the spot market is planned to transition to the T+1 settlement cycle in the fourth quarter of 2027. HKEX encourages market participants to begin assessing their operational readiness, systems, and processes as early as possible according to this anticipated implementation timeline. HKEX further indicated that after determining the final T+1 operational model, corresponding amendments will be made to the Exchange Rules, Clearing House Rules, and Listing Rules, with details to be announced in due course. Charles Li: T+1 Enhances Hong Kong's Core Competitiveness HKEX CEO Charles Li stated that they are committed to ensuring that Hong Kong's market infrastructure keeps pace with the times and aligns with global market development trends and best practices. Stakeholders have previously responded to the discussion document and supported HKEX in advancing this important market reform. He further noted that adopting the T+1 settlement cycle will further enhance Hong Kong's core competitiveness, making trading safer and faster, while laying the foundation for future infrastructure optimization and innovation. Adjusting Operational Processes to Achieve T+1 Regarding the T+1 mechanism, HKEX indicated that it proposes to adjust certain operational processes within the spot market trading cycle, while the existing arrangements for trade execution will remain unchanged. The various proposals aim to allow post-trade activities to be completed earlier on the trading day (T day), providing market participants with more time to prepare for smooth settlement on the next business day (T+1). HKEX further stated that related measures include adjusting the settlement procedure timetable and delivery-related processes to ensure that settlements can be conducted timely and orderly within the shortened settlement cycle. The existing cash and securities settlement framework and multi-batch settlement processing structure will remain unchanged. The document notes that since the time for post-trade operations will be shortened, HKEX also recommends extending the service hours for settlement-related activities, such as inputting settlement instructions and matching, allowing participants to handle post-trade procedures more flexibly before settlement. The existing settlement risk management framework will continue to apply, but individual timetables will be slightly modified to accommodate the new settlement cycle Earlier T+1 Discussion Document Gains Market Support The Hong Kong Exchanges and Clearing (HKEX) published a discussion document on T+1 settlement in July 2025, indicating that stakeholders in various markets strongly support the adoption of a T+1 settlement cycle for the Hong Kong stock spot market, as major global markets have already adopted or will soon adopt shorter settlement cycles. HKEX stated that in response to feedback on the discussion document, it will explore establishing a new workflow platform for institutional stakeholders such as investment fund managers, custodians, and brokers to help enhance their operational efficiency and align with the T+1 settlement cycle
