TMTPOST -- Futu Securities and Tiger Brokers, two prominent cross-border online brokerage platforms, have further restricted account openings for residents of mainland China. Under the latest regulatory requirements, Futu Securities has updated its account-opening conditions. Currently, mainland Chinese clients must hold proof of overseas permanent residency to open an account. Customer service from Futu NiuNiu emphasized that the company is undergoing a system upgrade. At present, only clients with Hong Kong or Macau ID cards can open accounts. Once the system upgrade is complete, mainland Chinese clients will be able to open accounts using a combination of their mainland ID and proof of overseas permanent residency.
