July 18, 2025: U.S. President Trump signs the "Guiding and Establishing the National Innovation for U.S. Stablecoins Act" (GENIUS Act), marking the first time the United States has established a regulatory framework for payment stablecoins through federal legislation. At the time, the industry widely regarded this as a milestone in crypto asset regulation. Yet, one year later on July 18, 2026—the statutory deadline for rulemaking—major regulators including the OCC, FDIC, NCUA, and the Treasury Department have failed to issue any final implementing regulations. All 10 proposed rules (NPRMs) remain at the public comment stage, with some comment periods even extended into August. Behind this regulatory "no-show" lies a compliance maze for a stablecoin market now exceeding $314 billion.
One Year Deadline Passed: Which Rules Are Still Unresolved?
Article 13 of the GENIUS Act clearly requires the OCC, Federal Reserve, FDIC, NCUA, and Treasury Secretary to issue implementing regulations within one year of the Act’s effective date, using a "notice and comment" process. As of July 18, 2026, this statutory deadline has been breached.
According to rulemaking trackers from Paradigm and Chapman Law, these agencies released a total of 10 proposed rules (NPRMs) over the past year, but none have been finalized. By agency: the Treasury issued four, covering state regulatory assessment standards, foreign issuer registration requirements, and anti-money laundering guidelines; the OCC issued two, focused on approval and oversight standards for federally chartered payment stablecoin issuers; the FDIC issued one, targeting reserve management and operational standards; the NCUA issued one, proposing to allow federally insured credit unions to participate in stablecoin issuance; and one was jointly issued by federal banking regulators to coordinate regulatory expectations.
The OCC led with its proposed rule in February 2026, followed by the FDIC and Treasury. The OCC’s comprehensive proposal was published in the Federal Register in March, covering requirements for reserve assets, capital, liquidity, custody, risk management, and reporting. The FDIC put forth prudential standards in April, addressing reserves, capital, redemption, custody, and risk management. On June 22, the Federal Reserve, FinCEN, OCC, FDIC, and NCUA jointly released a customer identification proposal, with comments open until August 21.
The law itself does not specify consequences for missing the deadline, nor does it provide an alternative timeline. But the regulatory vacuum is prolonging the wait for market participants.
Market Surpasses $314 Billion: Structural Expansion Amid Regulatory Uncertainty
Despite unresolved regulatory details, the stablecoin market has not stalled. As of May 26, 2026, the global stablecoin market cap reached $321.6 billion, up roughly 12% since the start of the year—a new all-time high. USDT supply rose to $189 billion, representing over 58% market share; USDC’s market cap is about $76.4 billion, accounting for roughly 23.8%. Together, they command more than 82% of the market.
This growth is primarily driven by Tether’s aggressive expansion—USDT saw a net increase of over $5 billion in the past 30 days, marking the largest monthly growth since 2025. Meanwhile, the combined market cap of USDC, USDe, and PYUSD fell by about $4.2 billion. This "issuance vs. contraction" divergence reflects a clear split in market sentiment toward different stablecoin types.
Notably, market cap rankings no longer align with actual capital flows. In the first half of 2026, USDC accounted for about 70% of adjusted stablecoin transaction volume, while USDT represented roughly 25%. In June, adjusted stablecoin transaction volume hit a record $1.79 trillion. USDT dominates commercial payments—settling about $95 billion in goods payments in the first half of 2026, far outpacing USDC’s $14 billion. In B2B payments, USDT’s share is as high as 92%. Conversely, USDC has established an advantage in DeFi infrastructure and institutional settlement.
This structural divergence means regulatory details will impact issuers in very different ways.
USDT’s Two-Year Countdown: Dual Challenge of Reserve Compliance and Market Position
The GENIUS Act grants stablecoin issuers a three-year compliance transition period, ending July 2028. One year after the Act’s enactment, USDT has about two years left to adjust for compliance. After the deadline, U.S. crypto platforms will not be able to offer stablecoins whose issuers have not met all regulatory requirements.
The core risk centers on reserve assets. The Act mandates that issuers fully back tokens with highly liquid assets—cash and U.S. Treasuries. Yet, Tether’s latest disclosures show that up to 25% of USDT reserves are still held in precious metals, loans, and Bitcoin—assets that do not meet the Act’s strict liquidity standards.
Tether’s ambiguous registration and operating locations further complicate compliance. Although Tether CEO Paolo Ardoino stated at the White House signing ceremony that the company would comply with the GENIUS Act and launch a U.S.-specific token, and in January 2026 introduced the federally regulated stablecoin USAT via Anchorage Digital, usage remains limited.
Anchorage Digital’s Head of Policy, Kevin Wysocki, expects institutional users to "switch to compliant, bank-issued digital dollars well before the 2028 deadline." For smaller platforms with lower risk tolerance, the likelihood of proactively delisting non-compliant stablecoins is rising.
USDC’s Compliance Advantage and Transatlantic Regulatory Differences
In contrast to USDT’s regulatory uncertainty, USDC issuer Circle has obtained an electronic money institution license under the EU’s MiCA framework, allowing services across all 27 EU member states. This approval enables USDC and EURC to operate under MiCA, becoming the main dollar and euro stablecoins on regulated European trading platforms.
On July 1, 2026, the EU MiCA transition period officially ended. Tether opted not to seek MiCA authorization—MiCA requires stablecoin issuers to keep at least 60% of reserves in European bank deposits, which conflicts with Tether’s U.S. Treasury-heavy reserve model. As a result, USDT was removed from European user trading pairs on platforms like Coinbase, Kraken, and Crypto.com.
However, electronic money institutions licensed under MiCA cannot operate in the U.S. market based on EU authorization, and vice versa—there is no mutual recognition or equivalency between MiCA and the GENIUS Act. Cross-border stablecoin issuers must comply with both regulatory regimes.
The U.S. GENIUS Act focuses on prudential oversight of payment stablecoin issuers, while the EU’s MiCA emphasizes risk prevention and a unified pan-European licensing system. This transatlantic regulatory incompatibility is increasing compliance complexity and operational costs for global stablecoin issuers.
Yield Ban, Regulatory Arbitrage, and Market Innovation
The GENIUS Act explicitly prohibits stablecoin issuers from directly paying interest to holders, aiming to prevent stablecoins from competing with traditional bank deposits. However, the market has shifted yield-generating activities to secondary markets and DeFi protocols—through "governance rewards" or liquidity provision. Lending markets, liquidity pools, and tokenized treasuries can still generate returns for stablecoin holders, though the source of yield has moved down a layer.
This yield ban has given rise to a new class of "yield-bearing stablecoins"—issuers use wrapper layers to pass Treasury yields to users. This innovation contributed to over half of new stablecoin supply in Q1 2026. The core regulatory conflict now centers on yield provisions—traditional banks worry these products divert depositors, while the crypto industry argues current compliant models should be recognized.
Meanwhile, anti-money laundering proposals from FinCEN and OFAC in April 2026 require issuers to freeze, block, or reject transactions that violate U.S. law, whether on regulated platforms or permissionless blockchain networks. Paradigm and Hyperliquid’s policy center warned that this rule could excessively intervene in decentralized finance, potentially forcing regulated stablecoins away from open blockchain networks. This adds another layer of tension to the rulemaking process.
From GENIUS to CLARITY: The Next Legislative Battleground
The delay in stablecoin regulatory details is not an isolated event—it reflects the broader lag in U.S. crypto asset legislation.
The "Digital Asset Market Clarity Act" (CLARITY Act) aims to establish the first comprehensive federal regulatory framework for digital assets in the U.S., clarifying whether digital assets fall under SEC or CFTC oversight. The Act passed the Senate Banking Committee in May 2026, but faces significant resistance. On July 13, 2026, the American Bankers Association (ABA) and Independent Community Bankers of America (ICBA) jointly wrote to Senate leaders, arguing that the Act’s stablecoin yield provisions would allow crypto firms to offer deposit-like services without being subject to the same regulations as traditional banks. On June 26, Galaxy Digital lowered the probability of the CLARITY Act becoming law in 2026 to 50%. As of July 16, Gate’s prediction market data puts that probability at just 35%.
Federally chartered crypto bank Anchorage Digital publicly called for Congress to pass the CLARITY Act on the one-year anniversary of the GENIUS Act, urging that clear market structure rules for stablecoins be extended to the broader digital asset ecosystem. This underscores that clarity in stablecoin regulation must be coordinated with a wider crypto market regulatory framework.
Conclusion
One year after the GENIUS Act was signed, U.S. regulators have yet to issue any final implementing regulations, with all 10 proposed rules still in the comment stage. Meanwhile, stablecoin market cap has surpassed $314 billion, and USDT and USDC have diverged significantly in both market ranking and actual capital flow roles. USDT faces a roughly two-year compliance window, with about 25% of its reserves potentially failing to meet the Act’s strict liquidity requirements; USDC, leveraging MiCA compliance, has gained a lead in the EU market, but transatlantic regulatory incompatibility is raising global issuers’ compliance complexity. The yield ban has spurred new market innovations, while tensions between anti-money laundering proposals and the DeFi ecosystem continue to build. The delay in stablecoin rulemaking is intertwined with broader U.S. crypto legislative stagnation—especially the stalled CLARITY Act. Until final rules are in place, the $314 billion market will have to navigate regulatory uncertainty.
Frequently Asked Questions (FAQ)
Q1: What is the rulemaking deadline for the GENIUS Act?
A1: The GENIUS Act was signed on July 18, 2025, requiring relevant regulators to finalize implementing regulations within one year—by July 18, 2026. That deadline has passed, and no final regulations have been issued so far.
Q2: What are the consequences of missing the deadline?
A2: The law itself does not specify consequences for missing the deadline, nor does it provide an alternative timeline. However, unfinished rules have left stablecoin issuers facing ongoing uncertainty regarding compliance obligations and regulatory expectations. The Act’s enforcement date remains January 18, 2027.
Q3: What regulatory risks does USDT face?
A3: USDT has about two years (until July 2028) to achieve compliance with the GENIUS Act. About 25% of its reserves are still held in precious metals, loans, and Bitcoin—assets that do not meet the Act’s strict liquidity requirements. If compliance is not achieved, USDT may risk being delisted from U.S. crypto platforms.
Q4: What regulatory advantages does USDC have?
A4: USDC issuer Circle has obtained an electronic money institution license under the EU’s MiCA framework, allowing operations in all 27 EU member states. This gives USDC clear regulatory compliance status in the EU market.
Q5: What are the main differences between MiCA and the GENIUS Act?
A5: There is no mutual recognition or equivalency between the two. The GENIUS Act focuses on prudential regulation of payment stablecoin issuers, while MiCA requires stablecoin issuers to keep at least 60% of reserves in European bank deposits. Cross-border issuers must comply with both regimes.
Q6: How does regulatory delay impact the market?
A6: Without final rules, stablecoin issuers, trading platforms, and investors face unclear compliance paths. Meanwhile, the market has developed yield-bearing stablecoins and other innovations, and potential conflicts between anti-money laundering rules and the DeFi ecosystem are brewing.
