Introduction
Stablecoins—digital tokens pegged to fiat currencies or other assets—have evolved far beyond crypto curiosities. Today they represent a critical battlefield in the U.S.–China competition for influence over global monetary systems.
1. What Are Stablecoins?
A stablecoin is a cryptocurrency designed to maintain stable value by being backed 1:1 with assets like U.S. dollars, gold, or government bonds (Atlantic Council).
Market capitalization reached roughly $240–260 billion in 2025, dominated (83%) by U.S.-based issuers such as USDT and USDC (BeInCrypto).
2. U.S. Strategy: Regulatory Clarity and Dollar Dominance
In March–July 2025, the U.S. advanced and enacted the GENIUS Act, establishing a comprehensive federal stablecoin framework: full asset backing, audits, consumer protections, and issuance controls (Wikipedia).
Proponents argue this strengthens the U.S. dollar’s position and draws institutional participation, while critics warn of risks like tax evasion, pseudo-anonymity, and fragile liquidity (washingtonpost.com).
3. China’s Response: Digital Yuan and Regulatory Counters
China regards U.S. dollar-backed stablecoins as a strategic threat. Former central bank officials warn they may deepen dollarization, undermining China’s monetary sovereignty (scmp.com).
As a response, China is pushing faster development of its digital yuan (e‑CNY) and exploring offshore yuan stablecoins—especially in Hong Kong as a regulatory sandbox (cryptonews.com).
4. Hong Kong’s Role: A Testing Ground
Hong Kong passed its Stablecoin Ordinance in May 2025, effective August, marking the city as a gateway for yuan-based stablecoins under strict reserve and licensing rules (Forbes, techinasia.com, Coinlive, Cointelegraph).
Fintech firms raised over $1.5 billion recently to build stablecoin infrastructure, while equities tied to Hong Kong issuance saw a market correction viewed by experts as healthy rebalancing (Reuters).
5. Strategic Stakes: Beyond Payment Rails
While some see stablecoins primarily as crypto tools, their broader implications include:
- Increasing demand for U.S. Treasurys, potentially lowering borrowing costs; issuers such as Tether already hold billions in U.S. government debt, influencing yields (arxiv.org).
- Competition between Project Agorá (Western‑led digital payments infrastructure) and mBridge (Asia‑led via central banks) illustrates the infrastructure divide (ft.com).
- China’s push for yuan-based systems is part of its broader ambition to shift global finance from the dollar zone (thediplomat.com, ccn.com).
6. Key Tensions & Perspectives
| Issue | U.S. Perspective | Chinese / Hong Kong Perspective |
|---|---|---|
| Currency Influence | Reinforce dollar‑based global finance | Counterbalance via yuan‑pegged systems |
| Regulatory Approach | GENIUS Act: streamlined licensing & audits | Hong Kong pilot regime; tight compliance |
| Sovereignty & Control | Encourages market competition | Prioritizes state control over value flow |
| Financial Stability | Concern over liquidity stress & bank runs | Risk of USD stablecoin dominance in Asia |
7. What’s Next?
- U.S.: Implementation of GENIUS enforcement, audit regimes, and integration with Wall Street players like Meta, Visa, Bank of America (BeInCrypto, Business Insider).
- China/Hong Kong: Launch of yuan‑pegged stablecoins via state‑backed firms like Ant Group, North King, and testing via Hong Kong compliance regime (Cointelegraph, cryptonews.com, Cointelegraph, Reuters).
- Global Competition: EU and UK exploring euro‑based alternatives under MiCA and FCA frameworks, pushing for multipolar stablecoin networks (axios.com, onchainstandard.com).
Conclusion
Stablecoins now stand at the crossroads of global finance and geopolitics. The U.S. seeks to institutionalize dollar-backed tokens under a regulated framework, while China accelerates its national digital currency ambitions through yuan alternatives. Whether stablecoins emerge primarily as financial tools or geopolitical instruments depends on how these systems evolve—and which financial blocs gain the trust of global markets.
