The rapid advancement of blockchain and distributed ledger technologies has propelled the growth of central bank digital currencies (CBDCs) and stablecoins, presenting both opportunities and regulatory challenges. With Hong Kong's Stablecoin Ordinance set to take effect on August 1, 2025, discussions around stablecoin development have reached unprecedented intensity.
The Case for Integrated RMB Stablecoin Development
Traditional offshore RMB business operates primarily in Hong Kong, Singapore, and London, while onshore-offshore RMB activities exhibit dual characteristics under controlled capital flows. While many suggest piloting offshore RMB stablecoins in Hong Kong before expanding to mainland free trade zones, we propose a synchronized approach:
- Proactive Sovereignty Protection: As USD-backed stablecoins dominate globally, China must actively develop regulatory frameworks to safeguard financial security and monetary sovereignty.
- Scale Economics: Hong Kong's limited RMB pool may struggle to support stablecoin economies of scale under 1:1 reserve requirements.
- Regulatory Leadership: Central authorities should guide stablecoin oversight while collaborating with Hong Kong regulators on identity verification, AML, and other frontier challenges.
Domestic Offshore RMB Stablecoin (CNYC) Models
Model 1: Consortium Approach
- Structure: Establish a Shanghai Free Trade Zone-based issuer through partnerships between clearing organizations, major banks, payment providers, and investment firms.
- Mechanism: Create wholesale markets for authorized institutions (e.g., digital RMB operators) to distribute CNYC to qualified entities/individuals.
Model 2: Bank-Led Issuance
- Path: Leverage digital RMB operator subsidiaries in Shanghai FTZ to mint CNYC directly on-chain.
- Considerations: Must differentiate from tokenized deposits and clarify operational pathways.
Implementation Requirements:
- Reserve assets: Minimum 80% high-liquidity instruments (cash, short-term bonds) with optional digital RMB reserves
- Compliance: Robust risk management, asset segregation, and scenario expansion aligned with FTZ reforms
- Access controls: "Electronic fencing" via smart contracts to limit usage to vetted entities during pilot phases
Offshore RMB Stablecoin (CNHC) Development
- Dual System: Mirror CNYC models in Hong Kong through joint ventures or mainland-authorized entities.
Use Cases:
- CNYC: Enhance cross-border trade efficiency
- CNHC: Strengthen Hong Kong's RMB hub status for RWA (Real-World Assets) and commodity settlements
Regulatory Coordination
Cross-border monitoring systems must:
- Track secondary market activities
- Detect unauthorized stablecoin holdings
- Prevent illicit fund flows

Implementation Challenges
Per BIS findings, stablecoins still face gaps in:
- Singleness: Uniform valuation across platforms
- Elasticity: Supply adjustment mechanisms
- Integrity: Settlement finality
Roadmap:
- Phase-wise scaling with risk controls
- Accelerated legal framework development
- Synergy with BIS's "Finternet" concept for CBDC-stablecoin interoperability
FAQ
Q: Why develop RMB stablecoins when digital RMB exists?
A: Stablecoins complement CBDCs by enabling programmable finance and cross-border interoperability while maintaining sovereign oversight.
Q: How does CNYC differ from CNHC?
A: CNYC serves mainland-controlled offshore flows, while CNHC operates under Hong Kong's regulatory regime for global RMB applications.
Q: What prevents stablecoin misuse?
A: Multi-layered KYC, transaction monitoring, and smart contract-based usage restrictions form a compliance firewall.
