Recent legislative movements in the United States and Hong Kong have drawn attention to stablecoins. The U.S. Senate passed the GENIUS Act, while Hong Kong established its Stablecoin Ordinance in May. Financial players like Circle, behind the USDC stablecoin, have seen significant market gains, and firms including JD.com and Ant Group are entering the space. So what’s behind this momentum?
Stablecoins are a type of cryptocurrency designed to minimize price volatility. Unlike Bitcoin, whose value can swing wildly, stablecoins like USDT and USDC are pegged to stable assets, most commonly the US dollar. For every unit issued, the backing entity holds equivalent reserves—typically in cash, government bonds, or other highly liquid assets.
This model allows issuers to earn returns on reserve assets while users enjoy relative stability. Tether, for example, holds over $98.5 billion in U.S. Treasury bonds as of March. With increasing adoption, the combined market capitalization of major stablecoins now exceeds $200 billion.
What Are Stablecoins?
Stablecoins belong to the cryptocurrency family but function differently from speculative assets like Bitcoin or Ethereum. They are price-stabilized by design, often through collateralization with fiat currencies or other low-risk assets.
USDT and USDC, the two largest stablecoins, maintain a 1:1 peg with the U.S. dollar. When a user purchases one of these coins, the issuer receives actual U.S. dollars and invests them in safe, liquid instruments such as short-term government bonds or repurchase agreements.
This structure allows the issuing companies to generate revenue through yield on reserves while users transact with minimal price uncertainty. It’s a system built on trust in the issuer’s ability to maintain sufficient reserves.
How Stablecoins Are Used
The primary use of stablecoins is not investment but payment facilitation, especially in cross-border and digital contexts.
Traditional banking transactions—particularly international ones—involve multiple intermediaries: originating bank, receiving bank, clearing networks, and sometimes currency conversion services. Each step adds time, cost, and complexity.
Stablecoins, operating on blockchain networks, allow near-instant settlement. Transactions are peer-to-peer, cutting out several layers of intermediation. This is especially useful in situations where local currency volatility is high or dollar access is restricted.
For example, in several African nations, dollar-pegged stablecoins are gaining traction as a more reliable medium of exchange than local currencies. They offer a way to hold and spend dollar value without a traditional bank account.
However, this efficiency comes with regulatory challenges. As the People's Bank of China Governor noted recently, stablecoins can “shorten cross-border payment chains” but also pose “significant challenges to financial supervision.”
Regulatory Responses and Motivations
Both the U.S. and Hong Kong have introduced regulations to address the risks associated with stablecoins, such as:
- Reserve Requirements: Mandating 100% backing with high-quality liquid assets.
- Anti-Money Laundering (AML) Compliance: Enforcing know-your-customer (KYC) and transaction monitoring.
- Short-Term Maturity Limits: As seen in the GENIUS Act, which requires reserves to be held in assets with maturities of 93 days or less.
These measures aim to prevent misuse while harnessing the benefits of faster, cheaper transactions.
From a U.S. perspective, dollar-denominated stablecoins extend the global reach of the U.S. dollar and create consistent demand for U.S. debt instruments. Tether, for instance, is now one of the largest buyers of U.S. Treasuries.
For China, engaging with stablecoins is more about strategic positioning. While mainland China prohibits cryptocurrency trading, Hong Kong is embracing digital asset innovation. This allows China to participate in financial digitization without loosening domestic controls.

How Stablecoins Differ from Digital Yuan
Digital yuan, or e-CNY, is China’s central bank digital currency (CBDC). Like stablecoins, it enables fast digital payments. However, there are key differences:
- Issuer: Digital yuan is issued by the People’s Bank of China, whereas stablecoins are issued by private entities.
- Backing: e-CNY is directly backed by the central bank, with no investment of user funds. Stablecoin reserves are often invested in interest-bearing assets.
- Monetary Impact: Since e-CNY operates like digital cash, it doesn’t complicate monetary policy in the way stablecoins might.
Hong Kong’s currency system offers a real-world analogy to stablecoins. The Hong Kong dollar is pegged to the U.S. dollar, and the Hong Kong Monetary Authority intervenes to maintain the exchange rate within a tight band. This requires large reserve holdings—similar to stablecoin issuers.
Frequently Asked Questions
What is a stablecoin?
A stablecoin is a digital currency designed to maintain a stable value by being pegged to a reserve asset like the U.S. dollar or gold.
Are stablecoins safe?
Their safety depends on the issuer’s transparency and reserve adequacy. Regulatory frameworks are improving oversight, but risks remain if reserves are not fully backed or audited.
Can stablecoins be used for illegal activities?
While early designs emphasized anonymity, new regulations require identity checks and transaction monitoring, reducing but not eliminating this risk.
How do stablecoins affect traditional banking?
They challenge traditional payment systems by offering faster, cheaper alternatives. However, they also rely heavily on the existing banking system for reserve management and liquidity.
What’s the difference between USDT and USDC?
Both are dollar-pegged, but USDC is often viewed as more transparent regarding its reserves and regulatory compliance.
Will stablecoins replace regular money?
It’s unlikely in the short term. They are more likely to coexist with traditional currencies and central bank digital currencies, serving specific use cases like cross-border payments.
Conclusion
Stablecoins represent a form of “regulatory arbitrage”—using technology to create more efficient payment systems ahead of legal frameworks. However, as regulations catch up, the gap between traditional and digital finance will narrow.
The ongoing integration of blockchain technology into mainstream finance suggests that stablecoins are here to stay. Their evolution will depend on balancing innovation with security, transparency, and compliance.
