In the rapid evolution of digital currencies, stablecoins have emerged as the "new darling" of capital markets. By 2025, the global stablecoin market has surpassed $200 billion in value, with daily trading volumes exceeding $100 billion, cementing their role as a "super bridge" between traditional finance and the crypto ecosystem. This phenomenon reflects intense博弈 between global regulators and market forces, signaling a pivotal shift in monetary systems. Here’s an in-depth analysis of how stablecoins transitioned from niche to mainstream.
Part 1: The Nature and Market Landscape of Stablecoins
1.1 The Triple Attributes of Stablecoins
Stablecoins (or "digital stable tokens") are blockchain-based currencies designed to maintain price stability through pegs to fiat currencies, commodities, or algorithmic mechanisms. Their core characteristics are:
- Digital Nature: As cryptocurrencies, they offer high efficiency, low costs, and global accessibility but face security risks and adoption barriers.
- Stability: Achieved via collateralization (fiat-backed like USDT, crypto-backed like DAI) or algorithms (e.g., defunct UST).
- Monetary Function: They act as "base money" in crypto ecosystems, facilitating 90%+ transactions due to price stability.
1.2 Market Structure: Dollar Dominance and Oligopoly
The stablecoin market is highly concentrated, with USD-pegged tokens like USDT ($155B market cap) and USDC ($616B) controlling 80%+ share. Key data:
| Rank | Stablecoin | Issuer | Type | Market Cap ($B) | 24H Volume ($B) |
|------|------------|-------------|--------------------|-----------------|-----------------|
| 1 | USDT | Tether | Fiat-collateralized| 1555 | 672.7 |
| 2 | USDC | Circle | Fiat-collateralized| 616 | 89.5 |
| 3 | DAI | MakerDAO | Crypto-collateralized| 54 | 181.3 |

Part 2: The Global Regulatory Race for Monetary Sovereignty
2.1 Comparative Regulatory Approaches
- US: The GENIUS Act mandates 100% USD reserves, extending dollar hegemony into crypto.
- EU: MiCA regulations classify stablecoins as ART/EMT, allowing flexible reserves.
- Asia: Singapore and Hong Kong adopt pragmatic licensing frameworks but lack scale to lead.
2.2 Can Stablecoins "Save" the Dollar?
Despite USD stablecoins dominating, their impact on sustaining dollar霸权 is limited:
- Minimal debt relief: Stablecoins hold just 0.4% of US debt (mostly short-term T-bills).
- Structural challenges: Fiscal deficits and geopolitical shifts outweigh crypto-market influence.
Part 3: Future Trends—How Stablecoins Will Reshape Finance
3.1 Synergy with Real-World Assets (RWA)
Stablecoins enable fractional ownership and liquidity for tokenized assets (e.g., real estate), merging TradFi and DeFi.
3.2 Disrupting Cross-Border Payments
Stablecoins slash costs (<0.0001% vs. 6.62% for banks) and settle transfers in minutes, not days.

3.3 Market Projections
By 2028, stablecoins could hit $2 trillion市值, accelerating digital capital flows and posing currency substitution risks for emerging markets.
