Futu and Changqiao have initiated a cleanup of accounts opened with false supporting documents and those without assets or positions. These accounts are being closed as part of the effort to ensure compliance and integrity. Additionally, the Futu NiuNiu app has introduced a new feature allowing users to update their identity information, assuring customers that holding compliant overseas identity documents will not impact their account activities. This move follows recent reports that some Hong Kong banks are requiring applicants to declare the source of funds when opening investment accounts, highlighting a broader trend towards increased scrutiny and regulatory compliance in financial services.
