Banks can now verify data that Mainland customers present from Chongqing without the original documents crossing the boundary. Loan applications are one of the first use cases.
On 14 October 2026 the Hong Kong Monetary Authority welcomed the launch of the Chongqing–Hong Kong Cross-Boundary Data Validation Platform. It is one of the Policy Address measures to encourage the orderly flow of financial elements between the Mainland and Hong Kong.
The platform lets a Hong Kong bank verify data that a customer presents from Chongqing, using blockchain technology and hash values, without the original data or documents being transferred across the boundary. The initial use cases include account opening and loan applications. The platform is operated by Chongqing Credit Co., Ltd and WeBank Technology Services Limited. It follows the Shenzhen–Hong Kong platform, which the HKMA says has already been used across multiple banks and business scenarios.
For lenders with Mainland-connected borrowers, the change is in what can be checked. A Hong Kong lender assessing a borrower with income, assets or a business in the Mainland has usually had to rely on copies the borrower supplied. Validation against the source, with the borrower's authorisation, turns those copies into verified data while leaving the personal data where Mainland rules require it to stay.
The platform is for participating banks. For bank lending teams, the operational question is how a validation result enters the credit file. A pass or fail, the date, what was validated and the customer's authorisation should all be recorded against the case, so that a reviewer can see that the income figure in the assessment was verified rather than accepted.
Expect this to widen. Each new city platform adds another source of verifiable data for cross-boundary borrowers, and lenders that can record verification consistently will be able to use them as they arrive.
