Interbank Account Data Sharing (IADS)

The IADS programme is formulated by the Hong Kong Monetary Authority and launched with the support of the banking industry. The IADS programme has established the rules and standards facilitating interbank customer-consented data sharing. This allows customers to securely and efficiently share their bank account data from one participating bank (Data Providing Bank) to other participating banks (Data Consuming Bank), subject to customer consent. Account data sharing could help digitalise banking operations, strengthen risk management of banks, and enhance customer experience.

Please refer to the “List of IADS Participating Banks”. For details of the IADS-related services offered by each bank, please contact the respective banks.

IADS participating banks must obtain customers’ explicit consent before sharing their account data.

Deposit account data of retail, corporate and small and medium-sized enterprises, limited to account availability, account status, account balances and transaction records.

Customer consent journey overview:

1. Customer initiates the consent procedures through the Data Consuming Bank’s platform (e.g. internet banking).
2. The platform above will redirect the customer to the internet banking of the selected Data Providing Bank.
3. The customer logs in to internet banking of the Data Providing Bank and then reviews and confirms the consent details.
4. If the customer wishes to grant the consent to multiple Data Providing Banks, repeat the above three steps for each selected Data Providing Bank.

Since the user interface design and detailed procedures may vary with banks, please contact the respective banks for details.

Customers can view the current status of their consents and revoke their consents as required, through the internet banking of their Data Providing Banks at any time. Since the internet banking design and process flow may vary with banks, please contact the respective banks for details.

Examples of IADS use cases include:

Example 1: Loan application

Example 2: Consolidated account views

By consolidating and analysing customers’ account data across different banks, the Data Consuming Bank can offer tailored services to its customers, thereby enhancing the customer experience.
