"Treasury's finalized principles for assessing whether state regimes are substantially similar to the federal regulatory framework are critical in this process." — Sen. Cynthia Lummis (R-WY), Letter to Treasury Department, June 2026
The GENIUS Act's statutory implementation deadline of July 18, 2026 is 31 days away. Four federal agencies — the OCC, FDIC, Treasury, and FinCEN — are running parallel rulemaking processes, none of which have produced final rules. Comment periods closed between May 1 and June 9. Banks have lobbied for extensions. State regulators lack a certification pathway. The $307.5 billion stablecoin market, dominated by two issuers controlling over 80% of supply, faces a compliance gap that no amount of legislative clarity has yet closed.
This report examines the regulatory architecture taking shape under the GENIUS Act, the competitive dynamics between bank and crypto-native issuers, the yield prohibition debate, and the structural risks of a deadline that may arrive before the rules are ready.
The GENIUS Act — signed into law on July 18, 2025 after passing the Senate 68-30 and the House 308-122 — mandated that implementing regulations be promulgated within 12 months. That deadline falls on July 18, 2026.
As of June 17, 2026, the following proposed rules have been published, but none finalized:
| Agency | Rule Scope | Published | Comment Deadline | Final Rule | |--------|-----------|-----------|-----------------|------------| | OCC | Prudential framework for Permitted Payment Stablecoin Issuers (PPSIs) | Feb. 25, 2026 | May 1, 2026 | Pending | | FDIC | Requirements for FDIC-supervised PPSIs and insured depository institutions | Apr. 10, 2026 | June 9, 2026 | Pending | | Treasury | State regulatory equivalence ("substantially similar") principles | Apr. 1, 2026 | June 2, 2026 | Pending | | FinCEN/OFAC | AML/CFT and sanctions compliance for PPSIs | Apr. 10, 2026 | June 9, 2026 | Pending |
The OCC's proposed rule alone runs 376 pages. It establishes a comprehensive prudential, operational, and supervisory framework for PPSIs — covering national bank subsidiaries, federal thrifts, federally licensed nonbank issuers, larger state-licensed issuers migrating to federal oversight, and foreign issuers operating in the United States.
Banks have actively lobbied for extended timelines. According to CoinDesk, banking industry groups in April 2026 argued that all concurrent rulemaking efforts are "directly contingent on the OCC's final framework," and that overlapping comment periods create compliance uncertainty.
The practical concern: achieving Permitted Payment Stablecoin Issuer status is not automatic. According to TRM Labs, applicants undergo formal review covering financial condition, governance structures, policies and procedures, and proof of auditor engagement. Issuers must also demonstrate the "technological capacity to freeze or restrict transactions upon lawful direction."
The stablecoin market has grown from $229.2 billion in April 2025 to $307.5 billion as of June 2026, according to AirdropBee's market data. That growth occurred entirely under the shadow of GENIUS Act implementation.
Market concentration remains extreme:
| Issuer | Stablecoin | Market Cap | Share | |--------|-----------|------------|-------| | Tether | USDT | $186.8B | 60.7% | | Circle | USDC | $75.8B | 24.7% | | All others | Various | $44.9B | 14.6% |
Tether and Circle collectively control 85.4% of stablecoin supply. This duopoly exists against a regulatory backdrop designed to expand competition — particularly from U.S. banks.
Actual stablecoin payment volume (excluding trading and automated transfers) reached $390 billion in 2025, more than double the 2024 figure, according to CoinDesk. B2B payments accounted for approximately $226 billion, growing 733% year-over-year. Visa's stablecoin settlement program hit a $4.5 billion annualized run rate by January 2026.
Juniper Research projects cross-border B2B stablecoin transactions at $13.4 billion in 2026, rising to $5 trillion by 2035.
The GENIUS Act created a federal pathway for U.S. banks to issue payment stablecoins under existing regulators. The result: traditional finance institutions entered the market within months of the law's passage.
JPMorgan launched its JPM Coin deposit token (JPMD) for institutional clients on Coinbase's Base network in November 2025, according to Messari. Its blockchain unit Kinexys is expanding JPMD natively to the Canton Network with phased integration through 2026.
Fidelity announced its Fidelity Digital Dollar (FIDD), an Ethereum-based stablecoin fully backed by U.S. dollars and high-quality cash equivalents, issued through Fidelity Digital Assets and aimed at both retail and institutional investors.
SoFi and other bank-adjacent firms have signaled intent to enter the market, per Eco's tracking of bank-issued stablecoins.
On the crypto-native side, Circle completed its NYSE IPO on June 5, 2025 at $31 per share (ticker: CRCL). According to CoinGecko, the combined effect of GENIUS Act alignment, SEC broker-dealer rules, FIS partnership, and IPO validation gave USDC structural advantages in U.S. institutional adoption. Circle's public-company disclosure obligations now mirror the transparency requirements of the GENIUS Act framework.
Tether took a different approach. In January 2026, it launched USAT — a federally regulated U.S.-market stablecoin issued through Anchorage Digital Bank under OCC supervision — effectively creating a compliance-first product for the U.S. while maintaining USDT's offshore structure.
The competitive landscape is splitting into two tiers: domestically regulated issuers (Circle, JPMorgan, Fidelity, Tether via USAT) and offshore-dominant issuers (Tether's main USDT operations out of El Salvador).
The GENIUS Act permits stablecoin issuers with less than $10 billion in consolidated outstanding issuance to opt into state-level regulatory oversight, provided the state's regime is certified as "substantially similar" to the federal framework. Certification requires approval from a new Stablecoin Certification Review Committee composed of Treasury, the Federal Reserve, and the FDIC.
Treasury published its proposed principles for evaluating state equivalence on April 1, 2026, with comments closing June 2. According to a June 16, 2026 letter from a bipartisan group of senators led by Cynthia Lummis (R-WY), the proposed principles failed to address the timeline and procedural requirements for state certification.
CoinDesk reported on June 16 that state regulators were concerned about being "left out" of the implementation process. The senators' letter stated: "The proposed principles were published by Treasury but did not address the timeline and procedural requirements related to state certification."
This creates a practical problem. Smaller issuers — the ones the dual-track system was designed to serve — have no path to compliance through state regulators as of June 17, 2026. They can apply for federal oversight, but that defeats the purpose of the state option. The Stablecoin Certification Review Committee has not announced a timeline for certifying any state regime.
The GENIUS Act explicitly prohibits stablecoin issuers from paying interest, yield, or similar benefits to holders. The OCC's 376-page proposed rulemaking extended this prohibition beyond issuers to include any affiliate or "related third party."
According to Perkins Coie's analysis, this broad interpretation creates tension with existing DeFi lending protocols, where stablecoin deposits generate yield through automated market mechanisms rather than issuer distributions.
The banking industry's position is that yield-bearing stablecoins would drain bank deposits. According to the Bank Policy Institute, U.S. transactional deposits are "at risk" from stablecoins if interest payments are permitted.
The White House Council of Economic Advisers took the opposite view. A report published in April 2026 concluded that prohibiting interest on stablecoins would do "very little" to protect bank lending while forgoing consumer benefits.
A May 2026 legislative compromise through the CLARITY Act attempted to resolve the tension by preserving reward programs while banning passive, bank-style interest. Whether this distinction survives final rulemaking remains unclear.
The economic stakes are significant. Reserve returns on stablecoin backing assets accrue to issuers. Circle, for example, generates revenue from interest on its USDC reserve portfolio — an income stream that effectively subsidizes a zero-cost product for users. This model is legal under the GENIUS Act. Direct interest payments to holders are not.
Tether operates out of El Salvador, placing its primary USDT operations outside GENIUS Act jurisdiction. The Act applies to U.S.-domiciled issuers and foreign issuers operating in the United States.
To address the U.S. market, Tether launched USAT through Anchorage Digital Bank — a federally chartered digital asset bank supervised by the OCC. This two-product strategy allows Tether to maintain its $186.8 billion offshore operation while offering a compliant vehicle for U.S. clients.
Tether also engaged KPMG to perform a full audit of its approximately $185 billion USDT reserves, with PwC hired to modernize internal reporting systems, according to CoinDesk reporting from March 2026. Previously, Tether relied on monthly attestations from BDO Italia — limited balance-sheet snapshots rather than comprehensive audits.
The GENIUS Act requires full audits for issuers with more than $50 billion in liabilities. Tether's USDT exceeds that threshold by $136 billion, but as a non-U.S. issuer, the statutory mandate does not directly apply. The KPMG engagement appears to be a voluntary compliance measure aimed at maintaining market credibility.
According to Georgetown's Journal of International Law, Tether's jurisdictional position highlights a structural limitation of the GENIUS Act: the legislation regulates issuance, not usage. USDT remains freely tradable on U.S. exchanges and DeFi protocols regardless of whether Tether itself holds a PPSI license.
The GENIUS Act represented a bipartisan achievement: the first comprehensive federal stablecoin framework, passed with supermajority votes in both chambers. Eleven months later, the rulemaking apparatus has produced 376-page proposals, overlapping comment periods, and zero final rules.
The statutory deadline does not automatically invalidate the law if missed, but it creates enforcement uncertainty. Can agencies take action against issuers operating without PPSI status if the application framework is not yet final? Legal scholars are divided.
What is clear: the $307.5 billion stablecoin market is not waiting for regulatory clarity. JPMorgan, Fidelity, and other banks are issuing under existing charters. Circle is leveraging its IPO-driven transparency. Tether is straddling jurisdictions. Smaller issuers — the ones the state-level track was designed to serve — are the most exposed to deadline risk.
The GENIUS Act gave stablecoins a legal definition. Whether it gives them a workable compliance framework by July 18 remains an open question.
