As global financial systems evolve in the digital era, the development of central bank digital currencies (CBDCs) and private stablecoins has become a strategic priority. In this context, the relationship between China’s onshore digital renminbi (RMB) and potential offshore RMB-denominated stablecoins is gaining increasing attention. Experts suggest that enhancing collaboration between Hong Kong and Shanghai—two of Asia's most influential financial hubs—could lay the foundation for a balanced, secure, and internationally competitive RMB digital ecosystem.
The Dual-Track Strategy: Onshore Digital RMB and Offshore RMB Stablecoins
According to Liu Bin, Director of the Financial Research Division at the Pudong Reform and Development Institute, China should pursue a dual-track approach in response to the growing dominance of dollar-denominated stablecoins like USDT and USDC. This strategy involves two complementary pathways:
- Accelerating the internationalization of the digital RMB
- Developing offshore RMB stablecoins via Hong Kong’s financial infrastructure
The digital RMB, also known as e-CNY, is already being tested domestically across major cities. However, its cross-border application remains limited. To expand its global footprint, Liu emphasizes establishing a Digital RMB International Operations Center—a dedicated platform to explore use cases in cross-border payments, trade settlements, and international投融资 (investment and financing).
At the same time, Hong Kong’s unique position as a global financial gateway with deep integration into both Chinese and Western markets makes it an ideal hub for launching offshore RMB stablecoins. These privately issued digital assets, pegged 1:1 to the RMB, could serve international investors and businesses seeking exposure to China’s currency without direct access to mainland financial systems.

Why Hong Kong-Shanghai Synergy Matters
Shanghai stands as China’s primary onshore financial center, home to the Shanghai Stock Exchange and a growing fintech ecosystem. Hong Kong, meanwhile, offers legal autonomy, free capital flows, and robust links to global markets—all critical for any offshore financial instrument.
By aligning their strengths, the two cities can create a coordinated regulatory and operational framework that supports both public and private digital currency initiatives. Key areas of cooperation include:
- Regulatory coordination: Establishing joint oversight mechanisms to prevent money laundering, ensure transparency, and maintain monetary stability.
- Technical interoperability: Aligning blockchain standards, wallet compatibility, and settlement protocols between onshore and offshore systems.
- Capital flow management: Designing controlled channels for fund conversion and repatriation to minimize systemic risks.
- Account integration: Enabling seamless connectivity between mainland digital wallets and Hong Kong-based financial institutions.
This synergy doesn’t mean duplication—it means specialization. Shanghai leads in CBDC deployment and domestic innovation, while Hong Kong drives offshore adoption through trusted financial institutions and regulated issuers.
Building a Benign Ecosystem: Competition vs. Complementarity
A common concern is whether offshore RMB stablecoins might undermine the authority of the digital RMB. However, when properly regulated, they can act as complements rather than competitors.
Consider this analogy: the physical RMB circulates within China under strict controls, yet offshore markets (like those in Hong Kong) have long traded RMB-denominated bonds and deposits—known as CNH (offshore RMB). This dual-market structure has helped internationalize the RMB without compromising domestic financial stability.
Similarly, a well-governed offshore RMB stablecoin market could:
- Facilitate smoother cross-border trade settlements
- Attract foreign investment into RMB assets
- Reduce reliance on USD in emerging market transactions
- Provide liquidity options for non-resident investors
Crucially, such stablecoins must be issued by reputable entities under clear regulatory supervision—potentially licensed through Hong Kong’s Securities and Futures Commission (SFC)—and backed by high-quality RMB reserves.

Addressing Risks: Stability, Oversight, and Trust
No financial innovation comes without risk. Dollar-based stablecoins have faced scrutiny over reserve transparency, centralization, and potential systemic impact. For an RMB-based system to gain global trust, it must learn from these lessons.
Key safeguards should include:
- Full reserve backing: All issued tokens must be 1:1 collateralized with RMB or highly liquid RMB-denominated assets.
- Independent audits: Regular third-party verification of reserves and smart contract integrity.
- Regulatory sandbox testing: Pilot programs under controlled environments before full rollout.
- Interoperability with CIPS: Integration with China’s Cross-Border Interbank Payment System to ensure compliance with anti-money laundering (AML) standards.
Moreover, cooperation between mainland regulators (like the People’s Bank of China) and Hong Kong authorities will be essential to prevent regulatory arbitrage and ensure consistent enforcement.
FAQ: Your Questions Answered
Q: What is the difference between digital RMB and an RMB stablecoin?
A: The digital RMB (e-CNY) is a central bank-issued digital currency—legal tender backed by the PBOC. An RMB stablecoin is typically issued by private entities but pegged to the RMB value, often used in decentralized finance (DeFi) or cross-border remittances.
Q: Can offshore RMB stablecoins replace the digital RMB?
A: No. They serve different purposes. The digital RMB focuses on domestic efficiency and monetary policy control. Offshore stablecoins cater to international users who need RMB exposure without accessing mainland accounts.
Q: Is Hong Kong already working on RMB stablecoin projects?
A: While no official stablecoin has been launched yet, Hong Kong has been actively exploring tokenized assets and regulatory frameworks since 2022. The city aims to become a Web3 hub in Asia, making RMB stablecoin development a likely future priority.
Q: How does this benefit international businesses?
A: It offers a more direct way to transact in RMB without navigating complex capital controls. This could lower transaction costs and increase efficiency in trade with mainland China.
Q: Will this challenge the US dollar’s dominance?
A: Not immediately. But over time, a robust dual-track RMB digital ecosystem could reduce dependency on USD in certain regions—especially among Belt and Road Initiative partners and ASEAN economies.

Toward a Unified Vision: 2025 and Beyond
While current efforts are still in exploratory stages, the vision is clear: a harmonized ecosystem where onshore innovation fuels offshore expansion, and where Hong Kong and Shanghai work not in parallel—but in partnership.
As geopolitical shifts accelerate de-dollarization trends, China’s ability to offer credible alternatives—through both state-backed digital currency and market-driven stablecoins—will shape its role in the next phase of global finance.
The path forward requires technical precision, regulatory clarity, and strategic alignment. But if executed well, this model could set a new benchmark for how nations balance control, innovation, and international openness in the age of digital money.
By fostering collaboration between Shanghai’s technological prowess and Hong Kong’s financial agility, China may not only strengthen its currency’s global standing but also redefine what a modern monetary system looks like in a digitized world.
