"Most payment stablecoins are distributed through exchanges and intermediaries — not directly by issuers. The rule must reflect how the market actually operates." — American Bankers Association, Comment Letter to OCC, May 1, 2026
Ten months after President Biden signed the Guiding and Establishing National Innovation for U.S. Stablecoins Act (GENIUS Act) into law on July 18, 2025, three federal agencies are simultaneously building the regulatory machinery to enforce it. The Office of the Comptroller of the Currency closed its 60-day comment period on a 376-page rulemaking on May 1, 2026. The FDIC approved its own parallel proposal on April 7. FinCEN and OFAC opened a joint anti-money-laundering rulemaking on April 8, with comments due June 9. Together, these three rulemaking tracks will determine how the $320.6 billion stablecoin market operates inside the United States.
The market is already bifurcating. Circle, now a publicly traded company (NYSE: CRCL) after its June 2025 IPO, holds $78 billion in USDC supply and meets the Act's reserve and disclosure requirements. Tether, operating from El Salvador with $183.4 billion in USDT outstanding, sits outside the federal framework entirely — but launched USAT, a U.S.-regulated token issued through OCC-chartered Anchorage Digital Bank, with $20 million in circulation as of March 2026. Meanwhile, Fiserv deployed FIUSD across its network of 10,000 financial institution clients, and the Bank of North Dakota became the first state entity to issue a branded stablecoin ("Roughrider Coin") on Fiserv rails. PayPal expanded PYUSD to 70 markets in March 2026. The question is no longer whether stablecoins will be regulated. It is which issuers will survive the compliance cost.
The GENIUS Act created a single statutory framework but delegated implementation to multiple agencies. As of May 2026, three parallel rulemakings are in progress:
| Agency | Action | Published | Comment Deadline | Scope | |--------|--------|-----------|-----------------|-------| | OCC | Notice of Proposed Rulemaking | Feb 25, 2026 | May 1, 2026 (closed) | Chartering, reserves, redemption, capital, wind-down for OCC-supervised issuers | | FDIC | Notice of Proposed Rulemaking | Apr 7, 2026 | ~Jun 2026 | Requirements for FDIC-supervised issuers and insured depository institutions | | FinCEN/OFAC | Joint Notice of Proposed Rulemaking | Apr 8, 2026 | Jun 9, 2026 | AML/CFT programs, sanctions compliance, BSA designation |
The staggered timelines mean final rules will not arrive simultaneously. The OCC, having closed its comment period first, is likely to finalize before year-end 2026. FinCEN and OFAC have proposed a 12-month implementation window after finalization, pushing full AML enforcement to mid-2027 at the earliest.
The OCC's February 25 proposal spans five parts of the Code of Federal Regulations and covers every phase of the stablecoin lifecycle. According to analysis published by Mayer Brown, Gibson Dunn, and Sullivan & Cromwell, the key provisions include:
Eligible Issuers: National banks and their subsidiaries, federal savings associations, federal branches of foreign banks, and nonbank entities seeking approval as "Federal Qualified Payment Stablecoin Issuers."
Reserve Requirements: One-to-one backing in U.S. dollars, short-dated U.S. Treasuries, or other high-quality liquid assets. Monthly public disclosure of reserve composition, audited by a registered public accounting firm.
Application Requirements: Nonbank entities must submit comprehensive applications including financial condition, business plans, compliance infrastructure, and biographical/financial reports for all directors, executive officers, and principal shareholders.
Wind-Down Planning: Issuers must maintain orderly wind-down plans, a requirement that mirrors bank resolution planning ("living wills") under Dodd-Frank.
Notable: The OCC proposal defers anti-money laundering rules entirely to the Treasury-coordinated FinCEN/OFAC rulemaking, creating a deliberate separation between prudential supervision and illicit finance controls.
The FDIC's April 7 proposal adds requirements specific to FDIC-supervised institutions:
The $5 million capital floor is modest compared to traditional bank charter requirements but represents a barrier for smaller fintech issuers. The 40% concentration limit will force issuers to diversify custodial relationships — a direct response to the risk that a single bank failure could impair stablecoin reserves.
The April 8 joint rulemaking marks a first: explicit statutory treatment of stablecoin issuers as "financial institutions" under the Bank Secrecy Act. According to analysis from Holland & Knight and DLA Piper, the proposal would require Permitted Payment Stablecoin Issuers (PPSIs) to:
The 12-month implementation timeline after finalization is longer than typical BSA rulemakings. According to Sullivan & Cromwell, this reflects the operational complexity of building blockchain-native compliance infrastructure capable of real-time sanctions screening across multiple chains.
The stablecoin market reached $320.6 billion in total capitalization as of May 2026, according to KuCoin research. The distribution:
| Issuer | Token | Market Cap | Market Share | Headquarters | |--------|-------|-----------|--------------|--------------| | Tether International | USDT | $185.5B | 57.9% | El Salvador | | Circle (NYSE: CRCL) | USDC | ~$78B | ~24.4% | United States | | PayPal / Paxos | PYUSD | ~$1.2B* | <1% | United States | | Tether / Anchorage Digital | USAT | $20M | <0.01% | United States | | Fiserv / Paxos | FIUSD | Early stage | N/A | United States | | Others | Various | ~$56B | ~17.5% | Various |
*Estimated from available data.
The structural imbalance is stark: Tether controls 57.9% of the market from a jurisdiction outside the GENIUS Act's reach. Circle controls 24.4% from within it. Every other U.S.-domiciled issuer combined holds less than 2%.
Circle (USDC): The most compliance-ready issuer. Circle completed its NYSE IPO on June 5, 2025 at $31/share, raising approximately $1.2 billion in primary and secondary capital. FY2025 revenue reached $2.7 billion (up 64% year-over-year). USDC supply grew 72% to $75.3 billion by year-end 2025 and continued to approximately $78 billion by April 2026. Reserves consist primarily of short-dated U.S. Treasuries and cash at regulated financial institutions. Circle already meets MiCA's Electronic Money Token standards in the EU. The company expanded USDC to 30 blockchains and launched Circle Payments Network.
Tether (USDT): Tether posted $1.04 billion in Q1 2026 net profit. Total assets reached $191.8 billion, with an $8.23 billion excess reserve buffer — a record. Reserves include $141 billion in U.S. Treasuries, $20 billion in physical gold, and $7 billion in Bitcoin, according to the BDO-attested Q1 2026 report. A KPMG audit commenced in March 2026, which would represent Tether's first Big Four audit. However, the Q1 report remains an attestation, not an audit. As noted by Senator Jack Reed during legislative debate, USDT "can be freely offered, sold, and used by Americans even though the GENIUS Act does not require Tether to provide a full accounting of the reserves backing its stablecoin."
Tether USAT (via Anchorage Digital): Tether's U.S. regulatory strategy. USAT launched January 27, 2026, issued by Anchorage Digital Bank, N.A., the only OCC-chartered digital asset bank. Tether invested $100 million in Anchorage. First attestation showed $17.6 million in reserves backing 17.5 million USAT outstanding as of January 31, 2026. By March 2026, supply reached approximately $20 million. Bo Hines, former Executive Director of the White House Crypto Council, was named CEO of Tether USAT. The token is structurally compliant with the GENIUS Act but represents 0.01% of Tether's total stablecoin footprint.
PayPal (PYUSD): Expanded to 70 markets in March 2026, up from two (U.S. and U.K.) at launch. Issued by Paxos on Ethereum and Solana. PayPal merchants can settle in PYUSD with near-instant finality. Fiserv and PayPal announced plans to make FIUSD and PYUSD interoperable across payment flows including cross-border transactions.
Fiserv (FIUSD): Launched on Fiserv's digital asset platform, leveraging Paxos, Circle, and Solana infrastructure. Available across Fiserv's network of approximately 10,000 financial institution clients and six million merchant locations processing 90 billion transactions annually. The Bank of North Dakota partnered with Fiserv to launch "Roughrider Coin," the first state-entity-branded stablecoin, available to banks and credit unions in North Dakota in 2026.
JPMorgan (JPMD): Through its Kinexys blockchain unit, JPMorgan plans to issue its deposit token natively on the Canton Network in partnership with Digital Asset. The phased rollout through 2026 focuses on issuance, transfer, and near-instant redemption. JPMorgan also partnered with Coinbase to provide 80+ million customers with crypto access pathways including USDC on Base.
The most contentious issue in the OCC comment period: whether stablecoin issuers can offer yield to holders.
The American Bankers Association, joined by 52 state bankers associations, submitted a comment letter urging the OCC to strengthen the prohibition on interest and yield payments tied to stablecoins. The ABA's argument centers on a structural reality: most stablecoins are distributed through exchanges and intermediaries, not directly by issuers. A yield prohibition that only covers direct issuer-to-holder payments would miss the primary distribution channel.
The Bank Policy Institute filed a joint trades comment letter echoing these concerns. The Crypto Council for Innovation submitted its own letter arguing for a more permissive framework.
The Brookings Institution submitted a public comment focused on capital requirements and reserve asset composition, noting that the proposed framework's capital standards need to account for the unique risk profile of stablecoin issuers versus traditional banks.
This fight reflects a deeper tension: traditional banks view yield-bearing stablecoins as a competitive threat to deposits. If a stablecoin can offer 4-5% yield backed by Treasury reserves while bypassing deposit insurance costs and reserve requirements, it becomes a direct substitute for a bank savings account — without the regulatory overhead.
The GENIUS Act implementation reshapes how economic value flows through the stablecoin stack:
Compliance Costs Rise: The combined requirements — OCC chartering, FDIC capital floors, FinCEN/OFAC AML programs, independent audits, wind-down planning — create a regulatory cost structure that favors scale. Circle's $2.7 billion annual revenue can absorb these costs. A startup with $20 million in stablecoin supply cannot.
Reserve Income Concentrates: Stablecoin issuers earn yield on reserves (primarily U.S. Treasuries) while paying zero interest to holders. Tether earned $1.04 billion in Q1 2026 alone from this spread. The yield prohibition, if enforced strictly, locks in this economic model: issuers capture 100% of reserve income. The ABA's push to close yield loopholes protects bank deposits but also protects issuer profit margins.
Market Access Narrows: The OCC's application requirements — biographical/financial reports for all officers and directors, comprehensive business plans, compliance infrastructure — create barriers that screen out smaller entrants. The FDIC's $5 million capital floor adds a modest but real threshold. The net effect: the number of permitted issuers will be small.
Offshore Arbitrage Persists: The GENIUS Act's jurisdiction focuses on U.S.-domiciled issuers. Tether's $185.5 billion USDT operates from El Salvador with U.S. Treasury-heavy reserves but no U.S. regulatory obligation to submit to OCC examination. The Act does grant the OCC enforcement authority over "foreign payment stablecoin issuers" in certain circumstances, but the practical reach of that authority over a company domiciled in a non-cooperating jurisdiction remains untested.
The GENIUS Act's implementation phase reveals a regulatory architecture designed for incumbents. The combined weight of OCC chartering requirements, FDIC capital floors, FinCEN/OFAC AML mandates, and independent audit obligations creates a compliance cost structure that only well-capitalized issuers can absorb. Circle, with $2.7 billion in annual revenue and a NYSE listing, is positioned to meet every requirement. Tether, with $1.04 billion in quarterly profit and $141 billion in Treasury holdings, has the financial capacity but not the jurisdictional exposure — hence the USAT hedge through Anchorage Digital.
The practical outcome is a two-tier market: regulated U.S. stablecoins subject to bank-grade supervision, and offshore stablecoins that continue to serve the majority of global volume without equivalent oversight. The GENIUS Act does not resolve this bifurcation. It formalizes it.
Whether the yield prohibition survives the final rulemaking will determine whether regulated stablecoins remain pure payment instruments or evolve into yield-bearing quasi-deposits. The banking industry's lobbying effort on this point is not abstract policy preference — it is an existential defense of the deposit franchise. The outcome will shape the economic model of every permitted issuer for the next decade.
