PANews reported on May 27 that, according to CLS, in response to the requirement that "some banks in Hong Kong require applicants to sign a declaration when opening investment accounts," the Hong Kong Monetary Authority (HKMA) told CLS reporters today that the relevant regulatory requirement was issued to all authorized institutions on May 22.

Materials provided by the Hong Kong Monetary Authority (HKMA) show that registered institutions are required to take three additional measures when opening and managing investment accounts for mainland investors. These include: 1. Closing investment accounts opened using suspicious or forged documents, identifying client investment accounts opened using suspicious or forged documents, including identity documents, since January 2023 or any other period specified by the HKMA; 2. Closing zero-balance, inactive investment accounts, specifically investment accounts held by mainland investors that have no asset balance as of May 22, 2026 (reference date) and have not had any activity initiated by the client in the 12 months prior to the reference date; 3. Obtaining a written statement from the mainland investor confirming that all funds used to support investment activities and related settlements are from legitimate sources outside mainland China when opening a new investment account.

According to the relevant documents, the new additional regulatory measures only apply to investment accounts, including investment accounts within integrated banking accounts. Non-investment functions (such as ordinary savings, current and futures deposits, payments, loans, and credit cards) are not within the scope of these measures. Furthermore, these additional measures apply to individual customers and not to corporate or institutional customers.
