Hong Kong Monetary Authority: Three new regulatory measures for Mainland investors' investment accounts, account opening verification will be retroactively reviewed until January 2023.

In response to the issue of "some banks in Hong Kong require a declaration to open an investment account," the Hong Kong Monetary Authority (HKMA) responded to reporters today, stating that the relevant regulatory requirements were issued to all recognized institutions on May 22nd. Materials provided by the HKMA show that registered institutions are required to take three additional measures when opening and managing investment accounts for mainland investors, including: 1. Closing investment accounts opened with suspicious or forged documents, identifying customer investment accounts that have used suspicious or forged documents to open accounts since January 2023 or any other specified period by the HKMA, including identity proof documents; 2. Closing zero-balance inactive investment accounts, specifically referring to investment accounts held by mainland investors with no assets balance as of May 22, 2026, and no customer-initiated activities in the 12 months prior to the reference date; 3. Obtaining a written declaration from mainland investors when opening a new investment account confirming that all funds used to support investment activities and related settlements come from legitimate sources outside of mainland China, etc. The related documents indicate that the additional regulatory measures only apply to investment accounts, including investment accounts within comprehensive bank accounts, and do not apply to non-investment functions; at the same time, these additional measures apply to individual customers and do not apply to corporate customers or institutional clients.
