Digital currencies are reshaping the global monetary landscape, with stablecoins potentially reinforcing the dominance of the US dollar, revolutionizing cross-border payments, challenging non-USD sovereign currencies, competing with central bank digital currencies (CBDCs), and posing regulatory dilemmas.
Key Types of Digital Currencies: Features and Future Outlook
1. Bitcoin (Representative of Cryptocurrencies)
Limitations:
- High volatility renders it unsuitable as a stable medium of exchange or store of value.
- Fixed supply limits its role in economic policy adjustments.
Future Role: Primarily as a speculative asset rather than a functional currency, though blockchain technology holds broader promise.
2. Libra (Stablecoin Pioneer)
Though discontinued, Libra’s proposal to merge Facebook’s global reach with the dollar’s reserve status spurred the rise of other stablecoins. Current stablecoin categories:
- Fiat-collateralized (e.g., USDT, USDC).
- Commodity-backed (e.g., gold-pegged).
- Hybrid models (fiat + crypto).
3. Digital Yuan (CBDC Leader)
Current Scope: Limited to replacing M0 (cash), restricting its use in B2B or financial transactions.
Expansion Potential: Extending to M1/M2 would enhance cross-border utility, especially via the mBridge network—a CBDC-based alternative to SWIFT.

The Rising Influence of Stablecoins
Global Trends:
- Market capitalization surged from $20B (2017) to $1.7T (2024), dominated by USD-pegged variants (USDT: $1.1T).
Roles:
- Crypto trading pair intermediary (50% Bitcoin/ETH trades use USDT).
- DeFi liquidity provider.
- De facto reserve asset in emerging economies.
Systemic Impacts:
- Cross-Border Payments: Blockchain-based transfers reduce fees and delays vs. SWIFT.
- Currency Sovereignty: Dollar-pegged stablecoins accelerate "crypto-dollarization" in inflation-prone nations (e.g., Latin America).
- CBDC Competition: Nigeria’s failed eNaira vs. thriving crypto adoption highlights stablecoins’ appeal.
- Regulatory Risks: Mixers enable money laundering; issuer mismanagement threatens monetary stability.
Strategic Responses
1. Expand Digital Yuan’s Utility
- Upgrade from M0 to M1/M2 to enable broader adoption and international use via mBridge.
2. Develop RMB-Backed Stablecoins
- Leverage Tencent, Alibaba, or TikTok’s global platforms to embed yuan in digital ecosystems.
3. Foster Crypto Innovation
- Pilot crypto-asset hubs in Hong Kong or Hainan to capture market opportunities.
4. Promote e-SDR at IMF
- Diversify digital reserve options to counter dollar dominance.
