Trading Regulations for Hong Kong Stocks Under Adverse Weather Conditions

In general, HKEX enforces trading suspensions during adverse weather conditions. The specific trading rules are as follows:

1. If Typhoon Signal No. 8 is lifted at or before 7:00 AM, trading proceeds as usual.
2. If the signal is lifted between 7:00 AM and 9:00 AM, the pre-market session is canceled; moreover, morning trading resumes two hours after the signal is lifted.
3. If the signal is lifted between 9:00 AM and 11:00 AM, both the pre-market and morning trading sessions are canceled; however, afternoon trading commences at the scheduled time of 1:00 PM.
4. If the signal is lifted between 11:00 AM and 12:00 PM, the start of the afternoon trading session is delayed accordingly.
5. If the signal is lifted after 12:00 PM, trading for the entire day is canceled.

New Arrangements for Continuous Market Operations During Adverse Weather Conditions

Furthermore, recent updates indicate that HKEX has introduced new arrangements for trading during adverse weather conditions. Effective September 23, 2024, the Hong Kong securities market will remain operational even under adverse weather conditions such as typhoons or Black Rainstorm Warnings. Consequently, investors will be able to trade Hong Kong stocks and derivatives as usual.

This change is intended to enhance Hong Kong's status as an international financial center and align with the practices of other major global stock markets. To facilitate this, HKEX strongly recommends that market participants adopt remote working models on trading days affected by adverse weather and utilize online services. In addition, physical trading locations are advised not to provide services to the public. Moreover, HKEX will offer special arrangements to market participants as necessary to ensure the smooth and orderly functioning of the market.
