Bank of China Hong Kong (BOCHK) has successfully completed its digital yuan (e-CNY) sandbox trial, marking a significant step forward in the adoption of central bank digital currency (CBDC) for cross-border payments. The trial, conducted in collaboration with Bank of China's mainland branches, involved real-world transaction scenarios and has paved the way for the upcoming inaugural "Cross-Border Shopping Festival" in Hong Kong.
What Was Tested in the e-CNY Sandbox?
The sandbox trial, approved by the Hong Kong Monetary Authority (HKMA) late last year, consisted of two priority experience phases. Eligible customers participated by using the digital yuan in genuine payment scenarios.
Participants topped up their e-CNY wallets via BOCHK's mobile banking app. They could then spend the digital currency at various merchants both in mainland China and Hong Kong. Spending in mainland China primarily focused on offline, small-value, high-frequency payments, covering everyday purchases like dining, transportation, and retail shopping.
A key success was the validation of digital yuan usage for consumption within Hong Kong. BOCHK also provided acquiring and HKD clearing services for local merchants accepting e-CNY, confirming the viability of the entire transaction process within the city.
The Technology and Collaboration Behind the Trial
Mr. Chen Guang, Deputy General Manager of the BOCHK Digital Currency Task Force, highlighted the technical cooperation that made the trial possible. The experiment connected Hong Kong’s Faster Payment System (FPS) with the digital yuan system operated by the Digital Currency Institute of the People's Bank of China (PBoC).
This integration allowed users free choice between digital yuan payments and local currency settlement across the border, creating a valuable model for future cross-border bilateral collaboration. A comprehensive report on the sandbox findings has been submitted to the HKMA.
Next Steps: Enhancing User Experience and Merchant Adoption
Based on feedback from both customers and merchants, BOCHK is focusing on several improvements. The bank aims to streamline the process from application to wallet activation, making it faster and more user-friendly.
A major focus is expanding the network of merchants that accept digital yuan. This expansion will allow mainland tourists to conveniently use e-CNY for payments in Hong Kong, which in turn reduces clearing costs for partner merchants and strengthens BOCHK's cross-border financial services.

Looking ahead, BOCHK plans to continue its promotion and experimentation with cross-border applications for the digital yuan and scenario validation for a potential digital Hong Kong dollar. The ultimate goal is to use central bank digital currencies to deliver tangible value to customers.
Launching the Cross-Border Shopping Festival
To further promote the adoption of e-CNY, BOCHK will again partner with Bank of China's mainland branches to launch the first "Cross-Border Shopping Festival" in Hong Kong. This event will offer selected customers digital yuan consumption vouchers, providing a hands-on experience of the convenience of cross-border payments with the digital currency.
This festival represents a practical and large-scale test of the digital yuan's utility in a real-world commercial setting, further cementing Hong Kong's role as a testing ground for innovative financial technologies.
