Circular to intermediaries HKEX annual rehearsal for trading system recovery

2026-10-30

The Securities and Futures Commission (SFC) issues this circular to remind intermediaries that Hong Kong Exchanges and Clearing Limited (HKEX) will conduct its annual rehearsal for emergency trading system recovery in the securities market from 11:00 am to 3:10 pm on 21 November 2026 (Saturday). The rehearsal will cover the following processes under the Hong Kong Investor Identification Regime (HKIDR):

• Submission of the BCAN-CID Mapping File and Reporting Forms to the data repository of the Stock Exchange of Hong Kong Limited (SEHK) (applicable to all Relevant Regulated Intermediaries1); and

• BCAN tagging for order submission to SEHK’s trading system (applicable exclusively to RRIs that are Exchange Participants (EPs)).

All RRIs are encouraged to participate in the rehearsal to familiarise themselves with the contingency procedures and related operational matters in the event of a service outage on SEHK’s trading system.

For the avoidance of doubt, only RRIs that are EPs are required to submit the Notification Form for Participation in the 2026 Market Rehearsal prior to the rehearsal, and the Rehearsal Evaluation Reply Form upon completion of the rehearsal. No enrolment will be required for non-EP RRIs. For further details, please refer to SEHK’s Circular dated 30 October 2026.

Should RRIs have any questions or encounter any irregularities during the rehearsal, please contact HKEX via the following hotlines or email:

• General enquiry (Hotline: 2840 3626)

• Technical enquiry (Hotline: 2840 3351)
