TMTPOST —Several banks in Hong Kong now require customers to sign a declaration confirming that all funds for investment activities and settlements come from legitimate sources outside mainland China when opening investment accounts offline, a rule that took effect on May 26. The new cross-border disclosure statement applies mainly to Chinese mainland residents and states that investment services are available only to those living or working in Hong Kong. The measure follows local regulatory adjustments to strengthen compliance on capital flows. This policy tightens oversight on cross-border investments in Hong Kong and may raise barriers for Chinese mainland investors accessing local financial markets amid stricter regulatory standards.
