Hong Kong's Digital Yuan Drive Aims to Connect Mainland and Global Markets

China Hong Kong is advancing its digital yuan (e-CNY) infrastructure, with authorities planning to raise transaction caps and expand wallet functionality to enhance cross-border payment integration with mainland China. Since the pilot program's expansion in May 2024, the number of local retail merchants accepting e-CNY payments has increased, reflecting the government's strategic push to integrate the digital currency into daily commerce. Christopher Hui, Secretary for Financial Services and the Treasury, emphasized that the e-CNY "provides residents of both regions with an additional secure, convenient, and innovative payment option, enhancing the efficiency of cross-border payment services and user experience while promoting mutual connectivity between the two places".

Current e-CNY wallet limits in China Hong Kong include a RMB 2,000 ($280) per-transaction cap, an annual cumulative limit of RMB 50,000 ($7,000), and a wallet balance restriction of RMB 10,000 ($1,400). These limits, which require only a local mobile phone number for wallet creation without needing mainland bank accounts or real-name verification, are under review. The Hong Kong Monetary Authority (HKMA) confirmed ongoing discussions with the People's Bank of China (PBoC) to upgrade wallet capabilities, including higher limits and expanded application scenarios. Lawmakers have also pressed for clarity on introducing real-name authentication features, which could align Hong Kong's e-CNY infrastructure with the advanced functionality available in mainland pilot cities.

Merchant adoption of e-CNY is growing, with the HKMA encouraging local banks to recruit more retailers to accept the digital currency. As of May 2024, residents can top up e-CNY wallets via the Faster Payment System (FPS) through 17 local retail banks, enabling cross-border payments in 26 mainland pilot areas, including the Guangdong-Hong Kong-Macao Greater Bay Area (GBA). The HKMA's Eddie Yue highlighted that the interoperability between FPS and the PBoC's e-CNY system marks the first global linkage of a faster payment system with a central bank digital currency (CBDC), underscoring progress in cross-border financial innovation.

China Hong Kong's e-CNY expansion is part of broader efforts to position the digital yuan as a tool for financial connectivity. The Multiple Central Bank Digital Currency Bridge (mBridge) project, which reached the Minimum Viable Product stage in June 2024, enables direct settlements between banks in participating jurisdictions, reducing cross-border payment costs. Authorities plan to expand mBridge's public and private sector participation while integrating more commercial banks, further cementing the e-CNY's role in global financial systems.

Future upgrades to e-CNY functionality may extend beyond consumer payments to include supply chain finance, cross-border wage payments, and enterprise-focused use cases. The government stressed the need to balance technological readiness, regulatory coordination, and user demand as it rolls out these enhancements. Meanwhile, concerns about e-CNY's potential to influence Hong Kong's financial ecosystem have prompted measures such as restricting peer-to-peer transfers and implementing real-name authentication to mitigate risks.

The HKMA also outlined plans to explore corporate applications of e-CNY, such as trade settlement, while continuing its collaboration with the PBoC to refine the digital currency's usability. These efforts align with China Hong Kong's role as a testing ground for the e-CNY outside mainland China, with officials monitoring usage patterns and gathering user feedback to inform future policy updates. As the e-CNY infrastructure matures, observers will closely watch for concrete changes to wallet limits and new application scenarios, which could shape the region's role in China's broader CBDC internationalization strategy.
