The global regulatory landscape for stablecoins is evolving rapidly as governments seek to balance innovation with financial stability. In 2023, key jurisdictions—including the United States, Singapore, and Hong Kong—introduced significant legislative developments aimed at bringing clarity and oversight to stablecoin issuance and usage. This article provides a comprehensive comparison of their regulatory approaches, focusing on core areas such as definition, licensing, asset backing, and cross-border applicability.
Focus on Payment-Oriented Stablecoins
All three jurisdictions prioritize regulation of stablecoins used primarily for payments—those designed or marketed for use in purchasing goods, services, or settling transactions. These assets act as bridges between traditional finance and the digital asset ecosystem, posing systemic risks if left unregulated.
In the United States, the 2023 draft legislation defines "payment stablecoins" as digital assets intended for payment or settlement that maintain a stable value relative to a fiat currency through redemption mechanisms or explicit promises by issuers. This broad definition captures major stablecoins like USDT and USDC.
Similarly, Hong Kong’s Monetary Authority (HKMA) targets "payment-related stablecoins" with potential for widespread adoption. The focus is on any stablecoin claiming to be pegged to fiat currencies—regardless of whether it uses algorithmic mechanisms or operates in retail, wholesale, or crypto trading contexts.
Singapore’s Monetary Authority (MAS) also emphasizes single-currency pegged stablecoins (e.g., USD or SGD-backed tokens), recognizing their critical role in payment and settlement systems. These are the primary targets of its proposed regulatory framework.

Legal Classification and Regulatory Jurisdiction
A major challenge in regulating stablecoins lies in their legal classification—specifically, whether they are securities, commodities, or a new category altogether.
In the U.S., this question has sparked intense debate between the Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC). While the SEC asserts jurisdiction over certain stablecoins—such as its claim that Paxos’ BUSD is an unregistered security—the 2023 draft legislation explicitly excludes stablecoins from the federal definition of “securities.” This move aims to prevent regulatory overreach and aligns with views from CFTC leadership that stablecoins resemble cash-like commodities.
In contrast, Hong Kong assigns clear authority to the HKMA for regulating stablecoin activities. However, it acknowledges potential overlap with the Securities and Futures Commission (SFC), which oversees virtual asset service providers (VASPs). Coordination between regulators will be essential to avoid duplication and regulatory arbitrage.
Singapore maintains unified oversight under MAS, which governs both banking and capital markets. This integrated structure simplifies jurisdictional clarity and enables consistent enforcement across sectors.
Licensing Requirements and Institutional Differentiation
All three regions agree that stablecoin issuers must be licensed—but differ in scope and implementation.
Under the U.S. proposal, only non-bank issuers require full licenses; banks may operate under existing approvals. Non-compliance carries civil and criminal penalties. The regulator must consider specific criteria when evaluating applications, ensuring transparency and fairness.
Hong Kong adopts a multi-activity licensing model. Entities engaging in governance, issuance, stability management, or wallet services for regulated stablecoins must obtain separate licenses. Both banks and non-banks can issue stablecoins, but each function requires distinct authorization.
Singapore’s approach mirrors the U.S., targeting issuers directly and applying differentiated rules for banks versus non-banks. The focus remains on ensuring robust operational standards regardless of institutional type.
Treatment of Algorithmic Stablecoins
Algorithmic stablecoins—those lacking full asset backing and relying on code-based mechanisms to maintain value—are treated with caution across all jurisdictions.
The U.S. 2023 initial draft introduced a two-year moratorium on "endogenously collateralized stablecoins," such as TerraUSD (UST), where value depends on another token issued by the same entity (e.g., LUNA). While the second draft removed this provision, the underlying concern remains: algorithmic models pose higher systemic risks.
Hong Kong effectively excludes algorithmic stablecoins from its licensing regime. One core requirement is that reserves must always match issued token supply with high-quality, liquid assets—something algorithmic models inherently fail to meet. Existing operators may need to restructure or withdraw services targeting Hong Kong users.
Singapore does not include algorithmic stablecoins in its primary regulatory framework for single-currency pegged tokens. Instead, they remain classified as digital payment tokens (DPTs), subject to anti-money laundering (AML) rules but not reserve or audit requirements.

Local Incorporation and Foreign Currency Pegs
Cross-border applicability varies significantly.
The U.S. applies its rules extraterritorially: any issuer targeting U.S. persons or using U.S.-based infrastructure must comply, regardless of where it is incorporated. There is no restriction on pegging to non-USD currencies.
Hong Kong prefers locally incorporated entities for easier supervision and enforcement. However, it is reviewing alternatives to this requirement while maintaining strict oversight over any activity promoting regulated stablecoins to the public or involving HKD-pegged tokens.
Singapore does not mandate local incorporation but prioritizes regulation of stablecoins issued within its borders. For globally issued tokens (e.g., USD-pegged coins), MAS proposes cooperation with foreign regulators and annual attestations proving equivalent reserve standards are met abroad.
Notably, Singapore restricts new single-currency stablecoins to those pegged to the Singapore Dollar or G10 currencies, ensuring strong backing from high-credit jurisdictions.
Asset Segregation and Reserve Requirements
Protecting user funds is central to all frameworks.
Both the U.S. and Singapore require strict segregation of reserve assets from corporate funds. Re-pledging customer deposits is prohibited. In Singapore, even custodial accounts must separate user holdings from issuer assets.
Reserve quality is equally important:
- Hong Kong mandates full backing with high-quality, liquid assets.
- Singapore specifies reserves must be cash, cash equivalents, or short-term government debt (under three months maturity), denominated in the pegged currency and issued by entities with AA- or higher ratings.
- The U.S. allows similar assets: USD, insured deposits, Treasury bills, repo agreements, and central bank reserves—ensuring at least 1:1 backing.
Disclosure, Attestation, and Auditing
Transparency builds trust.
- Hong Kong requires regular audits and disclosures by licensees.
- Singapore mandates monthly independent attestations published publicly, along with detailed reporting on reserve composition.
- The U.S. draft requires monthly publication of reserve breakdowns and internal attestation by the CEO—though it omits mandatory third-party audits in the initial version.
These measures aim to enhance accountability while minimizing operational burdens on compliant issuers.
Frequently Asked Questions
Q: Are all stablecoins considered securities in the U.S.?
A: No. The 2023 draft legislation explicitly excludes payment stablecoins from the definition of “securities,” resolving a key regulatory conflict between the SEC and CFTC.
Q: Can a foreign company get a stablecoin license in Hong Kong?
A: While preference is given to locally incorporated entities, HKMA is assessing alternative models. Final rules may allow foreign firms to qualify under certain conditions.
Q: Is Tether (USDT) compliant with these new frameworks?
A: USDT’s compliance depends on jurisdiction-specific reserve disclosures and licensing status. Its broad acceptance suggests ongoing alignment efforts with evolving standards.
Q: Why are algorithmic stablecoins banned or restricted?
A: Due to their lack of full collateralization and reliance on complex incentive mechanisms, they pose higher risks of de-pegging and collapse—as seen with TerraUSD in 2022.
Q: Will these regulations stifle innovation?
A: On the contrary—they aim to create a safe environment for innovation by establishing clear rules, protecting consumers, and fostering institutional participation.
Q: What happens to existing algorithmic stablecoins under these rules?
A: Most jurisdictions do not retroactively ban them but prevent new issuances or restrict market access—effectively phasing them out over time.
