Hong Kong’s banking system just got a lot less welcoming for mainland Chinese investors. Major banks including HSBC, Hang Seng Bank, and Bank of China (Hong Kong) have tightened or outright suspended the opening of new investment and wealth management accounts for mainland clients, following a regulatory push from the Hong Kong Monetary Authority that aligns with Beijing’s intensified crackdown on illegal capital routing.
What’s actually happening
The HKMA issued a circular around May 22-26, 2026, mandating that banks enhance their due diligence processes for mainland Chinese clients. The core requirement: written declarations from clients regarding the legal source of their funds.
Banks are now also compelled to scrutinize dormant accounts and close those that were established with forged or questionable documentation. The HKMA officially confirmed the new regulations were in effect on June 6, 2026.
China already limits individual capital outflows to $50,000 per year. Online brokerage platforms Futu and Tiger Brokers have restricted mainland clients’ ability to add new positions or transfer funds since June 12, 2026. HSBC began requiring mainland clients to submit source-of-funds declarations starting in late May 2026.
