Beijing wants Hong Kong to sow the seeds for the digital yuan. Will its plans bear fruit?

In September, Chief Executive John Lee Ka-chiu introduced Hong Kong's inaugural five-year plan, emphasizing the city's pivotal role in boosting the utilization of the yuan beyond mainland China. Recalling the global ambitions of the Chinese yuan, Xinmei Shen delves into Hong Kong's endeavors to test the interoperability of the e-CNY and other digital assets in a US Senate hearing.

Treasury Secretary Scott Bessent highlighted Hong Kong's "very large sandbox," suggesting Beijing's plans could bear fruit. Bo Tang, head of the Institute for Financial Research at Hong Kong University of Science and Technology, predicts the city could serve as a "laboratory for the interoperability of e-CNY, tokenized bank money, regulated stablecoins and tokenized assets," ultimately bridging China's next-generation financial infrastructure and global markets.

The People's Bank of China established a digital currency institute in 2016 and piloted the e-CNY in over 20 cities nationwide, accumulating 16.7 trillion yuan in transactions by last November. By the end of 2025, Project mBridge, a joint venture between the central bank and overseas institutions, facilitated 500 billion yuan in cross-border payments across 49 commercial banks.

Hong Kong, as the world's largest offshore hub for the yuan, holds over 1.1 trillion yuan in renminbi-denominated bank deposits, 1.27 trillion yuan in outstanding renminbi-denominated dim sum bonds, and numerous yuan liquidity facilities. Hong Kong's intensified efforts to forge an ecosystem and use cases for the yuan could further boost its e-CNY usage, with CBETS serving as an international access point for overseas institutions.
