On August 24, recent reports indicate that some banks in Hong Kong have initiated a source of funds declaration process for certain mainland investment clients, setting deadlines of August 20 (potential suspension of investment services if not submitted) and September 12 (potential termination of investment services if not submitted). According to various sources, some licensed institutions in Hong Kong, including HSBC Hong Kong and Chinese banks' branches, have indeed implemented these measures recently, primarily targeting long-term 'inactive accounts.' An HSBC spokesperson stated, 'When managing investment client relationships, we adhere to relevant regulatory requirements. Therefore, we invite the relevant mainland investors to provide self-declarations and confirm that the information they provided in the 'Know Your Customer' (KYC) and 'Customer Due Diligence' processes is current and valid. This helps us to continuously provide uninterrupted services to our clients. The latest declaration requirement applies only to our investment service clients.' It is understood that these measures by banks in Hong Kong are based on a notice issued by the Hong Kong Monetary Authority on May 22 (in conjunction with a circular from the Hong Kong Securities and Futures Commission), rather than a new policy or regulatory guidance.
