Hong Kong and China's securities regulators will begin sharing information regarding the identities of Chinese investors trading in Hong Kong via the Shanghai and Shenzhen stock connect schemes.

Hong Kong's Securities and Futures Commission said Dec. 14 that it signed an agreement with the China Securities Regulatory Commission to enable Chinese investors' identities to be shared with the Hong Kong watchdog starting in the first quarter of 2019. Hong Kong has already implemented similar rules for Hong Kong investors trading in China, effective Sept. 26.

The move aims to enhance market surveillance and combat cross-boundary market misconduct, the regulator said.
