Channels for mainland investors to trade in Hong Kong via illicit cross‑border routes are being narrowed. Several China-funded brokers in Hong Kong have tightened legacy mainland business: mainland logins to mainland accounts are restricted to sell and fund withdrawals only; deposits and buy orders are blocked. The enforcement hinge is whether the IP used to access a Hong Kong securities account appears to be located in mainland China. Xingzheng International and GUOTAI JUNAN International implemented such restrictions from Sept. 7 and Sept. 26 respectively; Oriental Financial Holdings has notified clients it will implement from October. Some China-funded brokers in Hong Kong have not yet restricted access, and some foreign brokers are monitoring developments. Industry contacts say both Chinese offshore and foreign brokers face ongoing cleanup of illegal mainland client business and that more offshore firms will adjust mainland legacy flows.
