In a watershed moment, President Donald Trump signed the GENIUS Act into law on July 18, 2025, creating the United States' first unified federal framework for dollar‑pegged stablecoins. Senators overwhelmingly passed the legislation in June (68–30), and the House followed in mid‑July (308–122).

Key Provisions of the Act

• Permitted Payment Stablecoin Issuers (PPSIs): Only approved banks, credit unions, federally or state‑licensed entities—and qualified foreign issuers—can issue stablecoins in the U.S.

• Strict Reserve Requirements: Issuers must maintain 1:1 backing in high‑quality liquid assets (e.g., U.S. dollars, Treasury bills), segregated in bankruptcy‑remote accounts with monthly attestations—and annual audits for larger entities.

• Licensing & Compliance: PPSIs must comply with AML/KYC rules, sanctions regimes, and possess the technical ability to freeze, seize, or burn tokens under lawful orders.

• Yield Ban: Issuers are prohibited from paying any interest or yield on stablecoin holdings to prevent risky usage of reserves. Critics warn this may reduce appeal as a store of value and drive adoption into DeFi platforms offering returns.

Foreign Issuers: The Unresolved Grey Area

While the GENIUS Act acknowledges foreign issuers, it leaves key questions unanswered:

• Foreign-issued stablecoins may enter the U.S. if the issuer operates under a "comparable" regulatory regime and registers with the OCC—but the law fails to define what constitutes "comparable."

• This ambiguity has raised fears of a “Tether loophole,” wherein issuers domiciled in more lightly regulated offshore jurisdictions circumvent U.S. standards—putting domestic issuers at a potential disadvantage.

• Former CFTC Chair Timothy Massad warned that this gap “was not sufficiently fixed,” and could incentivize offshore issuance, weakening U.S. market competitiveness.

Though Senate Banking Committee notes that foreign issuers must still meet technical capabilities (freeze/seize) and AML protocols comparable to U.S. issuers, enforcement ambiguity and lack of clear standards remain major concerns.

Market Reaction & Broader Context

• Industry leaders like Christian Catalini (MIT) predict that banks, fintechs, and retailers will now seriously consider launching their own stablecoins, integrating them into payment systems and treasury functions.

• The $163 billion USDT dominates 61% of stablecoin market cap, and its ability to continue operating offshore—is precisely the kind of advantage that U.S. issuers fear will go unchallenged under the new law.

• Analysts expect major companies like Coinbase (USDC), Visa, Mastercard, Amazon, Walmart, and even Western Union to accelerate involvement in stablecoin ecosystems in response to regulatory clarity.

Why the Foreign Issuer Gap Matters

• Competitive fairness: U.S. firms operating under strict regulatory burdens may lose market share to offshore stablecoins that skirt those obligations.

• Regulatory arbitrage: The absence of clear equivalence standards may incentivize issuance from jurisdictions with lighter oversight.

• Consumer confusion: End users might hold stablecoins governed by U.S. protections or from issuers exempt from them—making it harder to compare risk profiles.

Looking Ahead

• The effective date of the GENIUS Act is either January 18, 2027, or 120 days after federal regulators issue implementing regulations—whichever is earlier. After that, only approved PPSIs and compliant foreign issuers may issue, offer, or sell payment stablecoins in the U.S.

• From July 18, 2028, offering or sale of noncompliant stablecoins will be prohibited entirely—even from token issuers themselves.

• Meanwhile, the House is advancing the companion STABLE Act, which includes an 18‑month grace period and slightly different foreign‑issuer rules—raising the possibility of a reconciliation phase between the two versions.

The GENIUS Act marks a major milestone in creating a U.S. licensing and compliance regime for stablecoins, delivering transparency, reserve integrity, and consumer protections. But without clarity on what constitutes a "comparable" regime for foreign issuers, it risks enabling regulatory arbitrage—potentially disadvantaging U.S. issuers and undermining the Act's broader goals of standardization and market confidence.

As former CFTC Chair Timothy Massad notes, until these foreign issuer gaps are filled, questions about competitiveness and market equity will persist—and policymakers should prioritize defining and enforcing those standards if they want the Act to fulfill its full potential.
