Understanding Stablecoins: Definition and Mechanisms
The current U.S. tariff policies have weakened market confidence in the dollar. At the 2025 Lujiazui Forum, stablecoins emerged as a hot topic as potential dollar alternatives. Experts warned that dollar-pegged stablecoins could accelerate dollarization with significant side effects.
What Are Stablecoins?
Dollar stablecoins (USD Stablecoin) are cryptocurrencies pegged 1:1 to the U.S. dollar, designed to combine traditional fiat stability with crypto flexibility. Unlike volatile assets like Bitcoin (with 20% price swings), stablecoins maintain minimal fluctuations (0.5%), making them ideal for payments, settlements, and hedging.
Key mechanisms include:
- Collateralization: For every stablecoin issued, $1 in cash/short-term U.S. Treasuries must be held (e.g., USDC maintains 101.2% reserves).
- Regulation: Under the 2025 U.S. Stablecoin Act, issuers undergo monthly audits and comply with anti-money laundering (AML) rules.
Types of Stablecoins:
- Fiat-Collateralized: Backed by cash/Treasuries (USDC, USDT).
- Crypto-Collateralized: Overcollateralized with crypto assets (e.g., DAI requires 150%-200% ETH backing).
- Algorithmic: Algorithm-controlled supply (high-risk, as seen in UST’s 2022 collapse).

Global Impacts of Dollar Stablecoins
Reinforcing Dollar Dominance
- Digital Dollarization: In high-inflation countries like Argentina, 30%+ citizens hold stablecoins (IMF 2024), undermining local currencies.
- Cross-Border Efficiency: USDT reduces remittance fees to 0.1% vs. banks’ 6.3% (World Bank).
Financial Market Risks
- DeFi Vulnerability: USDC’s 2023 depeg to $0.87 triggered $6.2B in DeFi liquidations.
- Regulatory Gaps: Only 35% of stablecoins meet FATF’s AML standards, enabling illicit flows.
Geopolitical Currency Competition
- CBDC Race: China’s digital yuan and EU’s digital euro aim to counter dollar stablecoins’ 90% cross-border crypto payment share (BIS).
- Data Sovereignty: U.S. demands access to global wallet data (e.g., Circle shared 2,000+ China-linked addresses).
China’s Strategic Response
Regulatory Measures
- Domestic Bans: Blocked 120 crypto exchange IPs (2024), cutting USDT trades by 82%.
- Hong Kong Pilots: Allows licensed dollar stablecoins with 100% reserves in Chinese banks.
Technological Countermeasures
- Digital Yuan Expansion: Processes $1.2B/month in Sino-Saudi oil trades via mCBDC Bridge (80% faster than SWIFT).
- Quantum-Resistant Tech: Prepping for post-2030 quantum computing threats to blockchain.
Global Alliances
- ASEAN Partnerships: Building a digital currency reserve pool against stablecoin runs.
- Rulemaking: Leading ISO standards for cross-border CBDC settlements (2025 draft).

FAQs
Q: Are stablecoins safer than Bitcoin?
A: Yes—their peg to stable assets minimizes volatility, but collateral quality matters (e.g., USDC’s Treasuries vs. USDT’s past commercial papers).
Q: Can China ban stablecoins entirely?
A: Domestically yes, but offshore hubs like Hong Kong adopt controlled experiments to retain financial competitiveness.
Q: Will CBDCs replace stablecoins?
A: Likely long-term; the Fed’s digital dollar could absorb private stablecoins, but hybrid systems may persist during transition.
Q: How do stablecoins affect inflation?
A: They can export U.S. monetary policy globally—if the Fed prints dollars, stablecoin inflows may spike foreign inflation.
Q: What’s the biggest stablecoin risk?
A: Reserve insolvency (e.g., Tether’s 2021 $41M fine for hiding gaps) or regulatory crackdowns freezing funds.
This analysis underscores stablecoins’ dual role as both enablers of financial inclusion and vectors of dollar hegemony. China’s multi-phase strategy—from defensive bans to digital yuan globalization—highlights the high-stakes race for monetary sovereignty in the crypto age.
