Open Banking in Hong Kong

Hong Kong's Open API Framework, published by the Hong Kong Monetary Authority (HKMA) in 2018, adopts a phased approach to open banking. The framework divides API implementation into four phases of increasing complexity and sensitivity, allowing banks to build capabilities progressively.

Phase I covers product and service information (deposit rates, loan offerings, branch locations), and Phase II enables new account applications and subscriptions through APIs. These phases launched in 2019 and provided a foundation for third-party integration. Phase III, which involves account information sharing with customer consent, began rolling out in 2021. Phase IV will cover transaction data and is currently under development.

A distinctive element of Hong Kong's approach is the Commercial Data Interchange (CDI), launched as a pilot in 2021. The CDI is a consent-based infrastructure that allows banks to access commercial data from sources such as utility companies and trade databases to support SME lending decisions. This addresses a key challenge in Hong Kong's economy where many small businesses lack sufficient credit history for traditional loan assessments.

By 2022, Hong Kong's banking sector had deployed over 1,500 open APIs, with major institutions like HSBC, Bank of China (HK), Hang Seng Bank, and Standard Chartered actively participating. The HKMA has emphasized a collaborative approach, working with the Hong Kong Association of Banks (HKAB) to develop common standards and implementation guidelines.

Hong Kong's framework is part of the broader Fintech 2025 strategy, which includes initiatives in Central Bank Digital Currency (e-HKD), regulatory technology, and cross-border financial connectivity. The HKMA's approach balances innovation with the stability requirements of one of the world's largest international banking centers.
