Stablecoins have surged into the global financial spotlight, drawing attention from institutions, investors, and regulators alike. As digital currencies continue to evolve, stablecoins stand out for their unique ability to bridge traditional finance with the fast-moving world of blockchain. In this article, we explore what stablecoins are, how they maintain stability, their real-world applications, and who’s behind their issuance—based on expert insights from Liu Ying, a researcher at the Chongyang Institute for Financial Studies at Renmin University of China.
What Is a Stablecoin? Where Does Its Stability Come From?
A stablecoin is a type of cryptocurrency specifically designed to minimize price volatility by being pegged to a reserve asset—most commonly a fiat currency like the U.S. dollar, but also commodities such as gold or even other crypto assets.

The primary goal of a stablecoin is to serve as a reliable store of value, unit of account, and medium of exchange in an otherwise highly volatile crypto market. Unlike Bitcoin or Ethereum, which can swing dramatically in value within minutes, stablecoins aim to provide consistency and trust.
Three Pillars of Stability
Value Stability Through Asset Backing
Most popular stablecoins operate on a 1:1 reserve model. For example, every USDC (USD Coin) issued by Circle is backed by one U.S. dollar or equivalent short-term U.S. Treasury securities held in reserve. If Circle issues 20 million USDC, it must first deposit $20 million in assets. This full collateralization ensures that users can redeem their tokens at face value, maintaining confidence in the system.While the stablecoin itself doesn’t fluctuate much, its stability depends on the underlying asset. If the U.S. dollar depreciates due to inflation or macroeconomic factors, the purchasing power of the stablecoin will reflect that change—it remains stable relative to its peg, not necessarily in absolute terms.
Technical Stability via Blockchain
Stablecoins run on public blockchains like Ethereum or Solana, enabling secure, transparent, and tamper-proof transactions. Every transfer is recorded immutably on the ledger, allowing anyone to verify balances and transaction history. Settlements happen in near real-time—often within seconds—compared to days in traditional banking systems.This technological foundation enhances trust and efficiency, making stablecoins ideal for both peer-to-peer payments and complex decentralized finance (DeFi) protocols.
Regulatory Oversight and Transparency
Regulatory frameworks are increasingly shaping the stablecoin landscape. Jurisdictions like the European Union, the United States, Japan, South Korea, and Hong Kong are either implementing or drafting rules to govern stablecoin issuance. These regulations typically require:- Full backing of reserves
- Regular third-party audits
- Public disclosure of holdings
Such oversight helps protect users and prevents systemic risks—though it's worth noting that not all stablecoins meet these standards. The collapse of algorithmic stablecoins like TerraUSD (UST) in 2022 serves as a cautionary tale about overreliance on unproven mechanisms without sufficient collateral.
In essence, stablecoins derive their reliability from a combination of asset-backed reserves, robust blockchain infrastructure, and growing regulatory scrutiny. They act as a financial bridge between centralized economies and decentralized digital ecosystems.
Key Use Cases of Stablecoins
Stablecoins have been around for over a decade and now serve multiple functions across both digital and traditional economies.
1. Crypto Market Trading and Hedging
In volatile markets, traders use stablecoins as a safe haven during downturns. Instead of converting crypto holdings back to fiat—which involves delays and fees—they switch into stablecoins instantly while staying within the blockchain ecosystem.
For example, when Bitcoin drops sharply, investors may sell BTC for USDT (Tether) or USDC to preserve capital without exiting crypto entirely.
2. Cross-Border Payments and Remittances
Traditional international money transfers can take 3–5 business days and incur fees as high as 6%. Stablecoins cut that time to seconds or minutes with negligible transaction costs—often less than $0.01.
This efficiency is transformative for migrant workers sending money home or businesses engaged in global trade. Companies are leveraging stablecoins to streamline supply chain financing and reduce liquidity friction.

3. Inflation Hedging in High-Risk Economies
In countries experiencing hyperinflation—such as Argentina, Nigeria, or Turkey—individuals and small enterprises are increasingly turning to dollar-pegged stablecoins to protect savings. By holding USDC or USDT, they effectively access a more stable currency than their local one, preserving purchasing power.
4. Decentralized Finance (DeFi) Applications
Stablecoins power lending, borrowing, yield farming, and derivatives trading on DeFi platforms. Because their value remains predictable, they’re ideal for smart contracts that require consistent pricing.
For instance, users can lend DAI (an over-collateralized crypto-backed stablecoin) on Aave and earn interest in real time—all without intermediaries.
Who Issues Stablecoins?
Stablecoin issuers fall into three main categories:
1. Dedicated Crypto Firms
Companies like Circle (USDC) and Tether (USDT) dominate the market. Circle went public in 2024 with a massive surge in share price—up 168% on its first day—and later rose nearly 750%. Tether, despite controversies, reported over $14 billion in net profit in 2024 alone.
These firms generate revenue by investing reserve funds into low-risk instruments like U.S. Treasury bonds—a model similar to money market funds.
2. Major E-Commerce Platforms
Retail giants are exploring stablecoins for faster settlement and reduced transaction costs. For example, JD.com has tested dual-currency stablecoin solutions for Hong Kong dollars and U.S. dollars. The goal? Accelerate cross-border payments and improve cash flow efficiency while earning returns on reserve assets.
3. Licensed Financial Institutions
Banks like Standard Chartered in Hong Kong and major European institutions are launching regulated stablecoins for wholesale settlements and institutional clients. These entities benefit from new revenue streams through payment processing fees and investment income—not traditional interest margins.
While motivations vary, the core strategy remains consistent: leverage trust in fiat-backed digital assets to expand market share in payments and financial infrastructure.
Frequently Asked Questions (FAQ)
Q: Are all stablecoins backed 1:1 by cash?
A: Not all. While reputable ones like USDC and regulated versions of USDT maintain full reserves, some rely on partial backing or algorithmic mechanisms. Always check audit reports from trusted firms like Grant Thornton or BDO.
Q: Can stablecoins lose value?
A: Yes—especially if confidence in reserves erodes or regulatory actions disrupt operations. Algorithmic models without collateral are particularly vulnerable, as seen with UST’s crash.
Q: How do I buy stablecoins?
A: You can purchase them on major cryptocurrency exchanges using bank transfers or credit cards. Ensure the platform complies with local regulations.
Q: Are stablecoins legal everywhere?
A: No—regulation varies by country. Some nations ban private stablecoins entirely, while others encourage regulated versions tied to national currencies.
Q: Do I earn interest holding stablecoins?
A: Yes—through DeFi lending protocols or centralized platforms offering yield-bearing accounts. However, higher returns come with increased risk.
Q: What’s the difference between fiat-backed and crypto-backed stablecoins?
A: Fiat-backed ones (e.g., USDC) use real-world assets like dollars; crypto-backed ones (e.g., DAI) use over-collateralized digital assets as security. The former is generally more stable; the latter promotes decentralization.
Final Thoughts
Stablecoins represent one of the most practical innovations in modern finance—offering speed, accessibility, and stability in a digital format. Whether used for trading, remittances, inflation protection, or DeFi participation, they’re becoming integral to both crypto-native users and mainstream financial systems.
However, users must remain vigilant about issuer credibility, transparency of reserves, and evolving regulations.
