Starting May 26, Hong Kong banks will require investors to sign a cross-border declaration confirming that funds originate from legitimate sources outside mainland China when opening investment accounts.

According to a Cailian Press report on May 27, starting May 26, Hong Kong banks introduced new documentation requirements for in-person investment account openings: clients must additionally sign the “Cross-Border Disclosure Statement (Applicable to Investment Account Applications)”. Multiple investors who applied for accounts at Chinese- and foreign-funded banks in Hong Kong on that day reported that some were halted mid-process and required to sign the new document before resuming their applications. The core provision of the statement mandates that applicants confirm “all funds used to support investment activities and related settlements originate from legal sources outside mainland China”; it also reminds mainland residents that investment account services are only available to those physically residing or working in Hong Kong. At least one Chinese-funded bank’s official customer service team confirmed to Cailian Press that this adjustment was mandated by “the latest circular issued by regulatory authorities”. Mainland investors who opened investment accounts between May 23 and 25 must now sign the updated cross-border statement; representatives of foreign-funded banks also verified this requirement is in line with local regulatory rules. No official written responses have been released by most banks to date.

Regarding existing clients, the same Chinese-funded bank representative noted that investment trading functions will be suspended until the supplementary signing is completed, though accounts themselves will remain active, with no impact on current holdings or assets; only new purchase transactions will be prohibited. Once the statement is signed, trading privileges will be restored within one business day, either by visiting a branch or submitting the form via email. This new regulation comes at a critical juncture: on May 25, three online brokerage firms — Futu Securities, Tiger Brokers, and Longbridge — were slapped with heavy fines by the Hong Kong Securities and Futures Commission over compliance issues, while regulators simultaneously underscored their intent to channel more cross-border investments through banking channels. Industry analysts believe this regulatory shift could re-establish the integrated compliance model of “banks + brokerages + wealth management” led by traditional banks as the primary pathway for mainland investors seeking opportunities in Hong Kong.
