Investor Identification Regime at the Trading Level for the Securities Market in Hong Kong

posted 2 years ago

By Rossana Chu:  


Currently, for securities orders placed by intermediaries for their clients, the trading system of The Stock Exchange of Hong Kong Limited (SEHK) only captures information of the intermediaries, but not of its clients which instruct the orders. When suspicious trading activities arise, the Securities and Futures Commission of Hong Kong (SFC) has to issue notices to the intermediaries to identify the underlying clients, and may not be able to deal with such activities as promptly as the regulator would like to. From the perspective of the intermediaries (including SFC licensed corporations and registered institutions), they have to incur substantial compliance costs in handling with SFC’s enquiries. Thus, the SFC determined to introduce a new investor identification regime for the securities market in Hong Kong so that securities trading orders can be traced to those who give instructions.


The Hong Kong investor identification regime will be launched in the later part of Q4 2022 at the earliest.

Under the new regime, a regulated intermediary is required to assign a unique Broker-to-Client Assigned Number (BCAN) to every client. Each BCAN should be mapped to the client’s identification data (CID). The intermediary should also submit the BCAN-CID matching files of its clients to the SEHK.

When the intermediary submits the client’s order to the SEHK trading system for execution or reports the off-exchange trade order to the SEHK, such on-exchange order or off-exchange trade report is required to include the relevant client’s BCAN.

Off-exchange trades refer to trades conducted outside SEHK’s trading system but are required to be reported to SEHK under the SEHK Trading Rules. They include trades matched between clients of an intermediate or two different intermediaries directly through an alternative liquidity pool as well as trades matched on a pre-IPO trading platform operated by an intermediary licensed or registered to provide automated trading services.

The new regime would facilitate market surveillance by regulators because the originators of the on-exchange orders and off-exchange trades can be identified via their BCANs.

Having said the above, the Hong Kong investor identification regime and the investor identification regime launched on 26 September 2018 for northbound trading under Stock Connect are expected to work independently.

Personal data privacy of clients

An intermediary has to collect each individual client’s CID, including name and identity document number, type, and place of issue. If the client has a Hong Kong identity card but uses different identity documents to open securities accounts, the intermediary should follow up with the client to update the CID with his/her Hong Kong identity card information.

To comply with the Personal Data (Privacy) Ordinance of Hong Kong, intermediaries have to obtain their clients’ consents before submitting their CID to the SEHK. Clients who do not give consents will not be able to purchase securities through the intermediaries but will still be able to sell their securities.

Also, the BCAN should not be generated, assigned or handled in a way which would identify any individual client, compromise the confidentiality of the client’s identity, or give rise to non-compliance with the applicable privacy laws.

With reference to the industry standards and practices, the SFC and SEHK have considered appropriate measures to ensure the security and confidentiality of CID in aspects including data transmission/storage, access to CID, incident management and cybersecurity.

Practical impacts

When taking steps to comply with the investor identification regime, intermediaries are enhancing data security for their clients. Some of them are taking this opportunity to make additional investments in financial technology at the same time, in order to further develop online and mobile clientele and businesses.

The new regime is also described as a “real-name system” for Hong Kong securities trading. In the past, there were incidents where different investors used the same securities account to participate in Hong Kong securities trading. This practice may cease because orders placed by persons other than the securities account holder will be tagged with the BCAN of the account holder who may no longer be willing to let other persons’ orders be taken by the regulators as his/her own orders.
