Stablecoins have emerged as a transformative force in the global financial landscape, evolving from simple payment instruments into foundational infrastructure for next-generation finance. With major regulatory milestones in key markets like the United States and Hong Kong, stablecoins are transitioning from experimental technology to regulated financial tools. This shift is unlocking new opportunities in decentralized finance (DeFi), cross-border payments, and real-world asset (RWA) tokenization—ushering in a new era of digital value exchange.
This article explores the fundamentals of stablecoins, their strategic importance for enterprises, the evolving regulatory environment, and their pivotal role in bridging traditional finance with blockchain innovation—particularly through the lens of RWA integration.
What Is a Stablecoin?
A stablecoin is a type of cryptocurrency designed to maintain a stable value by being pegged to an external reference asset, typically fiat currencies like the U.S. dollar or euro, but also commodities such as gold or short-term government bonds. Unlike volatile cryptocurrencies like Bitcoin or Ethereum, stablecoins offer price stability, making them ideal for everyday transactions, savings, and financial settlements.
Origins and Core Purpose
The emergence of stablecoins was driven by two key challenges in early crypto markets:
- Limited fiat on/off ramps: Traditional banks were reluctant to service crypto platforms due to compliance risks, making it difficult for users to convert between fiat and digital assets.
- High volatility of cryptocurrencies: With Bitcoin’s price swinging dramatically, traders needed a reliable unit of account for trading and pricing.
Stablecoins solved these problems by combining the efficiency and programmability of blockchain with the price stability of traditional money.

Types of Stablecoins
Stablecoins can be broadly categorized into three models based on how they maintain their peg:
1. Fiat-Collateralized Stablecoins
These are backed 1:1 by reserves of fiat currency or high-quality liquid assets (e.g., U.S. Treasury bills). The most prominent examples include:
- USDT (Tether): Launched in 2014, it remains the largest stablecoin by market cap.
- USDC (USD Coin): Issued by Circle, known for higher transparency and regulatory compliance.
Reserve assets are held in independent custodians and subject to regular audits to ensure full backing.
2. Crypto-Collateralized Stablecoins
Backed by over-collateralized crypto assets (e.g., ETH) locked in smart contracts. These operate on decentralized platforms like MakerDAO (DAI). Because collateral values fluctuate, systems require over-collateralization (e.g., $150 worth of ETH to mint $100 in DAI) and automated liquidation mechanisms.
3. Algorithmic Stablecoins
These rely on algorithms and market incentives rather than asset backing to maintain price stability. However, after high-profile failures like Terra’s UST in 2022, confidence in pure algorithmic models has waned significantly.
How Stablecoins Differ from Other Digital Currencies
| Feature | Stablecoin | Bitcoin/Altcoins | CBDC |
|---|---|---|---|
| Value Stability | High | Low (volatile) | High |
| Use Case | Payments, settlement | Investment, speculation | Retail payments |
| Issuer | Private entity or protocol | Decentralized network | Central bank |
| Backing | Fiat or crypto reserves | None (market-driven) | Sovereign guarantee |
While central bank digital currencies (CBDCs) like China’s digital yuan represent state-issued digital money, stablecoins are privately issued but increasingly regulated—blurring the lines between public and private digital money.
Market Landscape (as of June 30, 2025)
According to DefiLlama:
- Total stablecoin market cap: $253.6 billion
- USD-pegged stablecoins dominate: over 90% share
Top players:
- USDT: $158.5 billion (62%)
- USDC: $61.4 billion (24%)
- Others: DAI, USDe, BUIDL
Projections suggest the market could grow to $2 trillion by 2028, representing a compound annual growth rate (CAGR) of around 65% (per渣打 Bank estimates cited by U.S. TBAC).
Why Are Companies Launching Stablecoins?
Beyond speculation, major corporations—from tech giants to retail conglomerates—are exploring stablecoin issuance not just for profit, but as a strategic lever for business transformation.
Revenue from Reserve Yields
Fiat-backed stablecoins generate income through interest earned on reserve assets. For example:
- Tether reported $13 billion in net profit in 2024**, with **$7 billion coming from U.S. Treasury investments.
- Circle similarly earns yield on its USDC reserves.
This creates a sustainable revenue model akin to seigniorage in traditional banking.
Strategic Business Advantages
✅ Streamline Cross-Border Payments
Companies like JD.com aim to reduce international payment costs by up to 90% using proprietary stablecoins. By bypassing SWIFT and correspondent banks, they achieve faster settlement (minutes vs. days) and lower fees.
✅ Optimize Supply Chain Finance
Stablecoins enable real-time payments to suppliers and facilitate invoice financing based on verifiable on-chain trade data. This improves cash flow and reduces reliance on third-party credit providers.
✅ Build Closed-loop Ecosystems
Enterprises can create self-sustaining financial ecosystems where customers earn, spend, and save within the same platform—enhancing user retention and data monetization.
✅ Secure a Foothold in Digital Infrastructure
With central banks advancing CBDCs and fintech innovation accelerating, launching a stablecoin positions companies at the forefront of the digital economy—avoiding disruption by emerging players.
Why Regulate Stablecoins Now?
Rapid adoption has brought risks: reserve opacity (e.g., USDT controversy), de-peg events (UST collapse), and frozen reserves (USDC during banking crisis). These incidents prompted regulators to act.
In 2025, two landmark regulatory frameworks took shape:
🇭🇰 Hong Kong’s Stablecoin Ordinance
Effective August 1, 2025:
- Requires licensing for all stablecoin issuers
- Mandates 100% reserve backing in high-quality liquid assets
- Enforces strict KYC/AML standards
- Applies to both local issuers and foreign stablecoins pegged to HKD
Hong Kong aims to become a global Web3 hub by offering a clear, innovation-friendly framework.
🇺🇸 U.S. GENIUS Act
Passed by the Senate in June 2025:
- Defines stablecoins as non-interest-bearing payment tools
- Limits eligible issuers to banks and federally regulated non-banks
- Requires full reserves in cash, short-term Treasuries (<93 days), or central bank reserves
- Imposes monthly disclosure and independent audits
The U.S. focuses on preserving dollar dominance and preventing systemic risk.

How “Stablecoin + RWA” Bridges Real and Digital Worlds
Understanding RWA (Real World Assets)
RWA refers to the process of tokenizing physical or financial assets—like real estate, bonds, private credit, or carbon credits—into digital tokens on a blockchain. This enables fractional ownership, 24/7 trading, automated payouts via smart contracts, and global investor access.
As of mid-2025:
- Global RWA market size: $24.4 billion (RWA.xyz)
- Fastest-growing segments: private credit ($14.3B), U.S. Treasuries ($7.4B)
- Key players: BlackRock (BUIDL), Franklin Templeton (FOBXX), UBS
The Role of Stablecoins in RWA
Think of the relationship this way:
- Stablecoins = Digital cash
- RWA = Digital stocks/bonds/REITs
Just as you use dollars to buy securities in traditional markets, you use stablecoins to purchase tokenized RWAs.
🔗 Key Functions:
- Payment Rail: Stablecoins serve as the primary medium for buying and settling RWA trades.
- Value Anchor: They provide a stable unit of account amid crypto volatility.
- Yield Distribution: Returns from tokenized assets (e.g., bond coupons) are paid out in stablecoins.
- Liquidity Provider: Stablecoins fuel DeFi protocols that lend against RWA collateral.
For instance, BUIDL, BlackRock’s tokenized fund, maintains a $1 peg and distributes dividends in USDC—enabling seamless integration with DeFi lending pools.
China’s Approach: “Onshore Assets + Consortium Chain + Hong Kong Sandbox”
China is pioneering a hybrid model under Hong Kong’s Ensemble Sandbox, allowing mainland assets to go global via regulated tokenization:
| Project | Asset Type | Technology |
|---|---|---|
| Longxin Group EV Chargers | Future revenue rights | AntChain + IoT |
| GCL-Poly Solar Farms | Clean energy income | AntChain + Conflux |
| Xunying Mobility Swap Stations | Battery operations | AntChain + Public Chain |
These projects use permissioned blockchains for compliance while connecting to public networks for liquidity—a pragmatic balance between control and openness.
Even agricultural assets are being tokenized: the "Malu Grape RWA" project in Shanghai links digital tokens to physical grape harvests, enabling traceability and community engagement through gamified rewards.
Four Key Insights on Stablecoin Evolution
1. Stablecoins Don’t Create Money—but Speed It Up
Unlike fractional reserve banking, stablecoins don’t multiply money supply. But they dramatically increase velocity of circulation:
- A $100 deposit used to back a stablecoin can still circulate in traditional banking while its digital twin enables instant peer-to-peer transfers.
- Faster settlements mean quicker reinvestment cycles—boosting economic throughput without inflationary pressure.
2. Hong Kong Dollar Stablecoins Face Adoption Hurdles
While USD-backed stablecoins dominate globally, HKD-linked versions face limitations:
- Limited use cases outside B2B supply chains (e.g., JD’s internal payments)
- Smaller offshore user base compared to dollar networks
- Dependence on Southeast Asian market acceptance
Expansion will depend on C-side adoption and broader RWA availability.
3. RWA Is On-Chain Securitization—Success Hinges on Asset Quality
RWA mirrors traditional asset-backed securities (ABS), but with superior transparency and automation via blockchain. Success depends on:
- Reliable cash flows from underlying assets
- Accurate, real-time data feeds (IoT-enabled monitoring)
- Strong legal frameworks for ownership rights
- Liquid secondary markets
Until these elements mature, growth will remain incremental.
4. Balancing Decentralization with Regulation
True decentralization conflicts with regulatory demands for oversight. Most successful applications today operate under a "limited decentralization" model:
- Private or consortium chains for compliance
- Regulated issuers acting as trusted nodes
- Audited reserves and KYC enforcement
The future lies not in full decentralization or total central control—but in hybrid systems that combine efficiency with accountability.
Frequently Asked Questions (FAQ)
