[Mainland Stock Investors Clearing Underway: HSBC Hong Kong Requires Relevant Clients to Confirm Source of Funds by September 12] Odaily Planet Daily News – Reports indicate that HSBC Hong Kong has recently begun notifying certain mainland stock investment clients, requiring them to submit a 'Declaration for Account Opening/Maintenance' via the HSBC Hong Kong App by September 12 and update their contact information. The declaration includes confirming that the funds for investment activities originate from legitimate sources outside mainland China and that the bank may disclose personal information upon request by law enforcement or regulatory authorities. The notice also mentions that if the declaration is not submitted by August 20, investment-related services may be suspended; if it is still not submitted by September 12, investment-related services may be terminated. In response, an HSBC Hong Kong spokesperson told Jiemian News reporters: 'We adhere to relevant regulatory requirements when managing investment client relationships. Therefore, we invite relevant mainland Chinese investors to provide a self-declaration and confirm that the information provided during "Know Your Customer" (KYC) and "Customer Due Diligence" processes is up-to-date and valid. This helps us continue to provide uninterrupted services to our clients. The latest declaration requirement applies only to our investment service clients.' Jiemian News reporters learned that in May of this year, the Hong Kong Monetary Authority issued a notice on 'monitoring measures to be taken when opening and maintaining investment accounts with clients,' which included 'additional measures required when opening and managing investment accounts for mainland investors.' These measures specifically cover 'closing investment accounts opened with suspicious or forged documents,' 'closing zero-balance inactive investment accounts,' and 'opening new investment accounts,' among other aspects.
