Hong Kong Monetary Authority Mandates Three Additional Measures for Mainland Investors' Accounts, with Retroactive Reviews to January 2023

According to BlockBeats, the Hong Kong Monetary Authority (HKMA) on May 27 announced three additional measures for managing mainland investors' investment accounts, effective immediately.

The first measure requires authorized institutions to close investment accounts opened using suspicious or forged documents, with reviews dating back to January 2023. The second mandates closure of zero-balance dormant accounts held by mainland investors with no assets or customer activity in the 12 months preceding May 22, 2026. The third requires written confirmation from new mainland account holders that all funds supporting investment activities originate from legal sources outside mainland China. The measures apply only to investment accounts and individual customers, excluding savings, loans, and corporate accounts.
