The Bank of China (Hong Kong) has announced the successful completion of its digital renminbi (e-CNY) sandbox trial, marking a pivotal milestone in the development of cross-border digital currency applications. Building on this achievement, the bank is set to launch the first phase of a "Cross-Border Shopping Festival" in collaboration with mainland China’s Bank of China branches. This initiative aims to enhance the usability and accessibility of digital RMB for mainland visitors in Hong Kong, further integrating financial infrastructure between the two regions.
Successful Completion of the Digital RMB Sandbox Trial
In late 2023, the Hong Kong Monetary Authority (HKMA) approved the Bank of China (Hong Kong) to initiate a digital RMB sandbox trial. Since then, the bank has conducted two rounds of priority experience programs in partnership with its mainland counterparts, allowing eligible customers to use digital RMB in real-world transaction scenarios across Hong Kong and mainland China.
Participants in the trial linked their digital wallets through the Bank of China (Hong Kong) mobile banking app and made purchases at various merchants in both regions. In mainland China, digital RMB was primarily used for small-value, high-frequency transactions—such as dining, transportation, and retail shopping—demonstrating its practicality in everyday life.

Crucially, the trial also validated Hong Kong’s capacity to support digital RMB transactions. The bank provided acquiring and HKD clearing services for local merchants accepting e-CNY, confirming the technical and operational feasibility of cross-border digital currency usage.
Technical Integration and Regulatory Collaboration
The trial leveraged the HKMA’s Faster Payment System (FPS) and the People’s Bank of China’s digital currency infrastructure, enabling seamless cross-border payments with local currency settlement. This integration serves as a model for future bilateral cooperation in central bank digital currency (CBDC) deployment.
According to Chen Guang, Deputy General Manager of the Digital Currency Task Force at Bank of China (Hong Kong), the trial has delivered actionable insights. “We’ve submitted a comprehensive report to the HKMA and are now refining our digital RMB offerings based on feedback from both customers and merchants,” he said.
Key improvements will focus on streamlining the wallet registration process to enhance user experience and expanding merchant participation. By increasing the number of outlets that accept digital RMB, the bank aims to make payments more convenient for mainland tourists while reducing settlement costs for businesses.
Preparing for the First Cross-Border Shopping Festival
With the sandbox trial concluded, attention now turns to broader public adoption. The upcoming Cross-Border Shopping Festival will be a major step in this direction. During the event, select customers will receive digital RMB consumption red packets, allowing them to experience the speed, security, and convenience of cross-border digital payments firsthand.
This festival is not just a promotional campaign—it’s a strategic move to normalize digital RMB usage in Hong Kong’s retail ecosystem. By incentivizing trial use, the bank hopes to accelerate merchant onboarding and consumer familiarity.
Advancing Dual-Track Digital Currency Strategy
Looking ahead, Bank of China (Hong Kong) plans to pursue two parallel tracks: expanding digital RMB cross-border applications and exploring use cases for the digital Hong Kong dollar (e-HKD). These efforts align with broader regional goals of financial digitization and integration.
Chen emphasized that the ultimate objective is to deliver tangible value to customers. “Through CBDC innovation, we aim to simplify transactions, reduce friction in cross-border commerce, and strengthen Hong Kong’s role as a global financial hub.”
