In recent years, stablecoins have surged from niche crypto instruments to pivotal players in the global financial landscape. With market capitalization projected to exceed $250 billion by 2025, stablecoins are no longer just tools for cryptocurrency traders—they are redefining cross-border payments, challenging traditional monetary systems, and prompting regulators worldwide to act.
This transformation has sparked intense debate: Are stablecoins a revolutionary leap in finance or an overhyped extension of existing monetary structures? As markets react and governments legislate, it's crucial to cut through the noise and understand what stablecoins truly represent.
The Rise of Stablecoins: From Crypto Markets to Global Payments
Stablecoins are a type of cryptocurrency designed to maintain price stability by being pegged to external assets—most commonly the U.S. dollar. Unlike volatile digital currencies like Bitcoin, stablecoins serve as a bridge between traditional finance and decentralized ecosystems, offering predictability in value while enabling fast, low-cost transactions.
There are three primary types of stablecoins:
- Fiat-collateralized (e.g., USDT, USDC): Backed 1:1 by reserves in cash or short-term government securities.
- Crypto-collateralized (e.g., DAI): Over-collateralized with other digital assets and governed by smart contracts.
- Algorithmic (e.g., collapsed TerraUSD): Use algorithmic mechanisms to control supply and maintain price parity—though these carry high systemic risk.
Initially developed to solve on-ramping challenges for crypto exchanges, stablecoins quickly gained traction. Since Tether (USDT) launched in 2014, the sector has grown exponentially. By mid-2025, the global stablecoin market reached approximately $250 billion—up from just $20 billion in 2020.
Their appeal lies in four core advantages:
- Price Stability: With volatility typically under 0.1%, they function as reliable units of account.
- Cross-Border Liquidity: Transactions settle in minutes at a fraction of traditional wire costs.
- Diverse Backing Models: From dollar reserves to gold-backed tokens like PAXG, use cases continue expanding.
- Digital Economy Integration: Over 90% of trading volume on platforms like Binance uses stablecoins; more than 70% of DeFi lending is denominated in them.
In义乌 (Yiwu), China’s global trade hub, blockchain analytics firm Chainalysis estimates that over $100 billion in stablecoin flows occurred in 2023 alone. In the Philippines, nearly 40% of overseas remittances now flow through stablecoin channels, accounting for 18% of total remittances—a vital economic lifeline.
Yet, despite their utility, stablecoins are often confused with central bank digital currencies (CBDCs). The distinction is critical: CBDCs are sovereign-backed digital cash, issued by central banks and integrated into national monetary policy. Stablecoins, however, are privately issued, relying on asset reserves that may lack full transparency or regulatory oversight.
Regulatory Race: Can Stablecoins Go Mainstream?
As stablecoins gain real-world adoption, governments are racing to establish frameworks that balance innovation with financial stability.
The U.S. took a major step forward with the passage of the GENIUS Act (Guiding Establishing National Innovation in U.S. Stablecoins), which mandates that only U.S.-based entities can issue compliant stablecoins backed solely by cash or Treasury bills maturing within 93 days. This effectively ties stablecoin growth directly to U.S. monetary assets—boosting demand for short-term Treasuries while reinforcing dollar dominance.
“Stablecoins extend dollar influence onto the blockchain,” says Li Yang, academician at the Chinese Academy of Social Sciences. “They modernize payments, strengthen international dollar usage, and create new demand for U.S. debt.”
Other jurisdictions are following suit:
- South Korea plans to allow large firms to issue won-pegged stablecoins under new legislation.
- The European Union, via its MiCA regulations, tightens oversight on non-euro stablecoins.
- Russia experiments with RUBC, a hybrid gold- and dollar-backed stablecoin.
- Hong Kong enacted its Stablecoin Ordinance in May 2025—the world’s first comprehensive regulatory framework for fiat-referenced stablecoins.
Under Hong Kong’s regime, only licensed institutions can issue stablecoins for retail sale. A sandbox program has already tested models from consortiums including Standard Chartered and Hong Kong Telecom. However, due to strict capital, audit, and redemption requirements, only a limited number of licenses will be granted initially.

Challenges to Mainstream Adoption
Despite regulatory progress, integrating stablecoins into traditional finance faces significant hurdles.
High Compliance Costs Limit Competition
Regulation raises barriers to entry. According to industry estimates, annual operating costs for a compliant issuer range from HK$50 million to HK$80 million (~$6.4M–$10.3M USD). These include reserve custody, independent audits, real-time redemption systems, and anti-money laundering (AML) compliance.
Compare Tether (USDT), which reported $13.7 billion in profits in 2024 with fewer than 200 employees—an astonishing $68+ million per employee—largely due to minimal compliance spending. In contrast, Circle (issuer of USDC) invests heavily in transparency and regulation, resulting in higher costs and slower market penetration.
This “compliance premium” favors established financial institutions with existing infrastructure—like Fidelity or Standard Chartered—while squeezing out smaller players.
Transparency Gaps Undermine Trust
One of the most pressing concerns is reserve verification. While USDC undergoes regular attestations by major accounting firms, USDT still lacks full audits from the “Big Four.” This discrepancy fuels skepticism about whether issuers truly hold 1:1 backing.
As Zhao Binghao, director of the FinTech Law Institute at China University of Political Science and Law, notes: “The core issue is ensuring that circulating supply matches actual reserves—a challenge amplified when operations occur across opaque blockchains.”
Four Realities That Demystify Stablecoins
To separate hype from reality, consider these four clarifying perspectives:
1. Stablecoins Are Not a Monetary Revolution
Rather than creating new money, most stablecoins tokenize existing bank deposits. As邹传伟 (Zou Chuanwei), chief economist at Wanxiang Blockchain, explains: “They’re a blockchain mirror of the current system—not a replacement.”
Unlike central banks, stablecoin issuers cannot expand credit or respond to liquidity crises. In stress scenarios—like the 2022 TerraUSD collapse—they can de-peg rapidly, revealing fragility beneath apparent stability.
2. They Don’t Transcend Sovereign Control
While marketed as borderless, stablecoins still depend on underlying fiat currencies. A dollar-pegged coin derives its value from confidence in U.S. institutions—not decentralized consensus.
Moreover, without robust KYC/AML protocols, many operate in regulatory gray zones. As the Bank for International Settlements (BIS) notes, this undermines trust and enables illicit activity—key weaknesses compared to sovereign currencies.
3. Impact on U.S. Debt Markets Is Limited
Some suggest stablecoins could absorb U.S. debt pressure. But even if all $245 billion in dollar-pegged reserves were invested in Treasuries, it would represent less than 1% of the $36+ trillion national debt—and only in short-dated bills.
Worse, if mass redemptions triggered forced bond sales, they could destabilize markets rather than support them—a classic “impossible trinity” dilemma.
4. Their Role as Safe Havens Is Unproven
Despite claims of being “digital dollars,” research shows that during crypto market downturns, investors often flee from stablecoins—not into them. Over 90% of fiat-backed stablecoins see outflows during volatility spikes, suggesting limited避险 (safe-haven) functionality.
The Road Ahead: Coexistence Over Replacement
The future isn’t about replacing fiat—but coexistence among CBDCs, regulated stablecoins, and traditional banking systems.
For emerging economies, unchecked adoption of dollar-pegged stablecoins poses a “digital dollarization” risk—eroding local monetary sovereignty as citizens opt for more stable alternatives.
China’s response? Dual-track strategy:
- Accelerate RMB internationalization via payment infrastructure upgrades.
- Explore offshore RMB-backed stablecoins through Hong Kong’s regulated sandbox.
As IMF Deputy Managing Director Bo Li emphasized at the 2025 Summer Davos: “Global coordination is essential.” The IMF, FSB, and Basel Committee are developing international standards for digital currency governance.
