Deep Dive into the Stablecoin Landscape: Models, Mechanisms, and Hong Kong’s Potential

·

Stablecoins have become the backbone of the digital asset ecosystem, serving as a critical bridge between traditional finance and blockchain innovation. With monthly transfer volumes surging from $100 billion to $1 trillion over the past four years, stablecoins now account for over 60% of daily crypto trading volume. This article explores the core models behind stablecoins—fiat-backed, crypto-collateralized, and algorithmic—analyzes market dynamics, and evaluates Hong Kong’s potential to emerge as a regional hub for stablecoin innovation.

Understanding Stablecoins: Definition and Core Models

Stablecoins are cryptocurrencies designed to maintain a stable value by being pegged to external assets, typically fiat currencies like the U.S. dollar. According to the Bank for International Settlements (BIS), they are “cryptocurrencies whose value is linked to legal tender or other assets.” Unlike traditional fiat, which aims to preserve purchasing power over time, stablecoins focus on maintaining a fixed exchange rate with their underlying asset—most commonly at a 1:1 parity with the U.S. dollar.

This stability enables reliable use cases such as value storage, cross-border payments, and decentralized finance (DeFi) transactions. While all stablecoins aim for price stability, they achieve it through different mechanisms, broadly categorized into two approaches: asset-backed collateralization and algorithmic supply adjustment.

Key Stablecoin Models

  1. Fiat-Collateralized Stablecoins
    Backed 1:1 by reserves of fiat currency or short-term government securities (e.g., U.S. Treasury bills). Examples include USDT and USDC.
  2. Crypto-Collateralized Stablecoins
    Over-collateralized using volatile digital assets like ETH. These operate on smart contracts and rely on automated liquidation mechanisms. DAI and USDe fall under this category.
  3. Algorithmic (or Hybrid) Stablecoins
    Use code-driven supply adjustments or hybrid collateral models to maintain pegs. FRAX is a prominent example combining partial fiat backing with algorithmic control.

Each model balances trade-offs between decentralization, capital efficiency, and price stability.

The Global Stablecoin Market: Trends and Competitive Landscape

Dominance of the U.S. Dollar Peg

Over 99% of stablecoins are pegged to the U.S. dollar, reflecting its role as the global reserve currency. While alternatives exist—such as EURT (Euro), GYEN (Yen), and IDRT (Indonesian Rupiah)—their market presence remains minimal. Even gold-backed PAXG holds a niche position compared to dollar-denominated tokens.

This dominance underscores the importance of trust and liquidity: users gravitate toward assets with deep markets and strong institutional backing.

Market Share: USDT Leads, USDC Gains Ground

As of mid-2025, the stablecoin market exceeds $160 billion in total value locked (TVL), with:

USDT maintains its lead due to early adoption and broad exchange integration, while USDC has grown steadily thanks to regulatory transparency and DeFi adoption.

Top Stablecoins by Type

The top ten stablecoins reveal a clear hierarchy:

This diversity shows that while fiat-backed models dominate, innovative structures continue to gain traction in specific niches.

Holder Behavior: Trust After Crisis

A notable event in 2023 saw USDC temporarily lose its peg following Silicon Valley Bank’s collapse, causing a sharp drop in holder addresses. Although it recovered, many users migrated to USDT during the crisis—highlighting how confidence shifts rapidly during stress events.

In contrast, USDT has maintained steady growth in active addresses, reinforcing its status as the default on/off ramp for crypto traders.

How Major Stablecoins Work: Mechanisms and Trade-Offs

Fiat-Collateralized Stablecoins

Tether (USDT)

Launched in 2014, USDT pioneered the modern stablecoin era. Operated by Tether Limited (linked to Bitfinex), it uses a simple model:

  1. Users deposit USD into Tether’s bank accounts.
  2. Tether issues an equivalent amount of USDT.
  3. Tokens circulate across blockchains (Omni, ERC-20, TRC-20).
  4. Users redeem USDT for USD; Tether burns tokens and returns funds.

Tether claims full reserve backing via a Proof of Reserves system. Its reserves consist of:

With Q1 2025 profits hitting $4.5 billion and only ~100 employees, Tether operates with extraordinary efficiency.

USD Coin (USDC)

Developed by Circle and Coinbase in 2018, USDC emphasizes compliance:

Unlike USDT, Circle does not directly serve retail users—only approved partners (exchanges, institutions) can mint/redeem. This enhances control but limits accessibility.

First Digital USD (FDUSD)

Launched in 2023 by Hong Kong-based First Digital Trust, FDUSD rose quickly after Binance phased out BUSD and adopted FDUSD for launchpool mining.

Key features:

Its rise illustrates how exchange support + yield incentives can rapidly scale a new stablecoin.

Crypto-Collateralized Stablecoins

DAI (MakerDAO)

DAI is the leading decentralized stablecoin, governed by MKR token holders. Users lock ETH or other collateral in smart contracts (“vaults”) to generate DAI.

Key mechanisms:

MakerDAO also invests reserves in U.S. Treasuries via its "Endgame" plan, blending real-world assets (RWA) with DeFi innovation.

USDe (Ethena Labs)

USDe is a synthetic dollar using delta-neutral hedging:

  1. Deposit stETH (staked Ether)
  2. Simultaneously short ETH perpetual futures
  3. Maintain dollar-equivalent exposure regardless of price swings

Users earn high yields from:

This creates a “yield-at-mint” model—unlike traditional stablecoins that offer zero returns. However, risks include counterparty exposure, exchange concentration, and governance centralization.

Algorithmic Stablecoin: FRAX

FRAX uses a dynamic collateral ratio:

Arbitrageurs keep FRAX pegged:

FRAX deploys idle capital via its AMO (Algorithmic Market Operations) into DeFi protocols for yield generation.

Despite technical sophistication, algorithmic models struggle with scalability due to limited real-world utility.

Future Outlook: Can Hong Kong Become a Stablecoin Hub?

Challenges for Non-Dollar Stablecoins

While dollar-backed stablecoins dominate globally, regional alternatives face adoption hurdles:

However, Hong Kong presents unique opportunities for HKD-pegged and offshore RMB (CNH)-pegged stablecoins.

Regulatory Momentum

Hong Kong’s virtual asset licensing regime—effective since 2023—signals growing regulatory clarity. A formal stablecoin framework is expected soon, potentially enabling compliant issuance of local-currency tokens.

Use Case Opportunities

For HKD Stablecoins:

For Offshore RMB (CNH) Stablecoins:

Crucially, any successful RMB stablecoin must avoid conflicting with mainland monetary policy while unlocking offshore liquidity.

Building Sustainable Demand

To succeed, Hong Kong-based issuers should consider:

  1. Yield Incentives: Share investment returns from Treasury-like assets.
  2. Real-World Utility: Partner with payment gateways and e-commerce platforms.
  3. Hybrid Collateral: Combine CNH deposits with USD-denominated assets for stability.
  4. Regulatory Alignment: Ensure compliance with both HKMA and international standards.

Frequently Asked Questions (FAQ)

Q: What is the safest type of stablecoin?
A: Fiat-collateralized stablecoins like USDC are generally considered safest due to high transparency, regulatory oversight, and liquid reserves.

Q: Why did USDC lose its peg in 2023?
A: It was triggered by exposure to Silicon Valley Bank, which held a portion of USDC’s cash reserves when it collapsed. Circle quickly replaced those holdings, restoring confidence.

Q: Is DAI truly decentralized?
A: While governed by MKR voters, MakerDAO increasingly relies on centralized entities for RWA management—raising debates about its decentralization level.

Q: Can algorithmic stablecoins recover after UST’s failure?
A: Pure algorithmic models remain high-risk. However, hybrid designs like FRAX—with partial collateral—offer more sustainable paths forward.

Q: Are yield-bearing stablecoins risky?
A: Yes—high yields often reflect higher risk (e.g., leverage, counterparty exposure). Always assess underlying mechanisms before investing.

Q: Will Hong Kong launch its own stablecoin?
A: While no official government coin is planned, licensed private issuers may launch regulated HKD or CNH stablecoins under upcoming rules.

Final Thoughts

The stablecoin landscape reflects broader tensions in crypto: centralization vs. decentralization, yield vs. safety, innovation vs. regulation. While USDT and USDC dominate today, new models like USDe show that user demand for yield can drive rapid adoption.

For Hong Kong, the path forward lies not in replicating dollar pegs—but in leveraging its unique position as a gateway between East and West to build compliant, yield-generating stablecoins tied to HKD and offshore RMB, integrated into global trade and finance networks.

With clear regulation on the horizon and growing institutional interest, Hong Kong could become a proving ground for the next generation of digital money.
