"Stablecoins are still evolving; locking them into a single template makes little sense. Keeping room for state innovation under the GENIUS Act is central to the dual banking model and aligns with Congress's framework." — Brandon Milhorn, President and CEO, Conference of State Bank Supervisors
Five federal agencies are simultaneously drafting rules to implement the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act, signed into law in July 2025. The comment deadline for two of the most consequential proposed rules — FinCEN/OFAC's anti-money laundering framework and the FDIC's prudential standards for stablecoin issuers — closes June 9, 2026, three days from this publication. A third comment period, on Treasury's criteria for certifying state-level regulatory regimes, closed June 2.
The regulatory apparatus now taking shape will govern a stablecoin market worth approximately $313 billion, dominated by Tether's USDT ($188 billion, 58% share) and Circle's USDC ($78 billion, 25% share). The rules will determine which issuers qualify as "permitted payment stablecoin issuers" (PPSIs), what reserves they must hold, how quickly they must honor redemptions, and how they must police illicit finance on their networks. Implementation regulations must be finalized by July 18, 2026, with the Act taking full effect no later than January 18, 2027.
Industry stakeholders — from the Bank Policy Institute to the Blockchain Association to the Conference of State Bank Supervisors — are filing competing comment letters that expose deep structural disagreements over federal preemption, interest/yield prohibitions, and the treatment of foreign issuers. The outcome will reshape competitive dynamics between bank-issued and non-bank stablecoins, between federal and state regulators, and between U.S.-domiciled and offshore issuers.
The GENIUS Act establishes three pathways for entities seeking to issue payment stablecoins in the United States:
State-licensed issuers face a hard cap: no more than $10 billion in outstanding stablecoin issuance. Above that threshold, issuers must obtain federal supervision.
The Act mandates 100% reserve backing, prohibits payment of interest or yield solely for holding stablecoins, requires redemption within defined timeframes, and treats all PPSIs as "financial institutions" under the Bank Secrecy Act (BSA). The Federal Reserve Board, FDIC, OCC, NCUA, FinCEN, and OFAC each hold rulemaking authority over their respective jurisdictions.
According to the Chapman and Cutler GENIUS Act Rulemaking Tracker, the implementation has proceeded through a staggered series of proposed rules:
| Agency | Rule Published | Comment Deadline | Status | |--------|---------------|-----------------|--------| | Treasury (ANPRM) | Sept 19, 2025 | Nov 4, 2025 | Closed | | FDIC (Interim) | Dec 19, 2025 | Feb 17, 2026 | Closed | | NCUA | Feb 12, 2026 | Apr 13, 2026 | Closed | | OCC | Mar 2, 2026 | May 1, 2026 | Closed | | Treasury (State Certification) | Apr 3, 2026 | Jun 2, 2026 | Closed | | FDIC (Standards) | Apr 10, 2026 | Jun 9, 2026 | Open | | FinCEN/OFAC (AML/CFT) | Apr 10, 2026 | Jun 9, 2026 | Open |
Several critical implementation items remain unfinished: the Federal Reserve Board has not yet issued its licensing and substantive compliance rules, Treasury has not finalized its criteria for foreign issuer compliance or reciprocity determinations, and the Stablecoin Certification Review Committee — which will govern whether non-financial public companies can issue stablecoins — has no published operating rules.
The statutory deadline for final rules is July 18, 2026. Given the volume of outstanding comment letters and the complexity of interagency coordination, market participants and legal observers have flagged the risk of delayed finalization.
According to a Mayer Brown analysis published April 28, 2026, the FDIC and OCC proposals are broadly aligned on core requirements — 100% reserves, prohibition on yield payments, two-business-day redemption standard — but diverge on at least seven material points.
Multi-brand issuance. The FDIC permits a single issuer to offer multiple stablecoin brands with segregated reserves. The OCC has not authorized multi-brand issuance and solicits comment on whether to prohibit it.
Reserve concentration limits. The FDIC caps exposure to any single financial institution at 40% of reserve assets. The OCC imposes additional concentration limits and requires a portion of reserves to be held as insured deposits.
Liquidation triggers. The OCC mandates automatic liquidation without redemption fees after 15 consecutive business days below minimum reserve levels. The FDIC retains discretionary authority over liquidation and solicits comment on whether a 15-day automatic trigger is appropriate.
Redemption surges. The OCC provides an automatic 7-calendar-day extension when redemptions exceed 10% of total outstanding value within 24 hours. The FDIC leaves extension authority to agency discretion.
Credit restrictions. The FDIC explicitly prohibits providing customer credit for stablecoin purchases. The OCC contains no comparable restriction.
Deposit insurance. Both agencies agree that stablecoin reserves held at insured depository institutions receive only $250,000 coverage per PPSI — not per individual stablecoin holder. Pass-through deposit insurance is not available for stablecoin holders. The FDIC clarified that tokenized deposits, by contrast, receive the same insurance coverage as traditional deposits.
Contingency planning. The FDIC requires written contingency plans proactively, before any shortfall occurs. The OCC allows remediation plans only after noncompliance is detected.
These divergences create potential for regulatory arbitrage between OCC-chartered and FDIC-supervised issuers, a point that several comment letters have flagged.
The FinCEN/OFAC joint proposed rule, published April 10, 2026, represents the first time stablecoin issuers will be classified as "financial institutions" under the BSA. According to the FinCEN fact sheet accompanying the proposal, PPSIs will be required to:
The sanctions compliance requirement breaks new regulatory ground. According to Sullivan & Cromwell's analysis of the proposal, PPSIs would bear responsibility for identifying sanctioned persons who hold or trade their stablecoins across secondary markets — not just at the point of issuance. Failure to take "appropriate action" against sanctioned addresses exposes issuers to criminal penalties and civil penalties imposed on a strict-liability basis.
FinCEN and OFAC propose a 12-month implementation period after the final rule is issued, to allow PPSIs time to build the required technical and compliance infrastructure.
The most politically charged dispute in the GENIUS Act implementation concerns the boundary between federal and state authority. The Act establishes a dual regulatory structure: issuers below the $10 billion threshold can operate under state supervision, provided Treasury certifies the state regime as "substantially similar" to federal standards.
The Conference of State Bank Supervisors (CSBS) submitted a comment letter, reported by Payments Dive on June 6, 2026, pressing Treasury to recalibrate its approach. CSBS argues that Treasury is overstepping by effectively requiring states to adopt the OCC's specific implementing regulations rather than merely meeting the Act's statutory baseline.
"The statute does not direct states to follow or defer to the OCC or any other federal payment stablecoin regulator," the CSBS wrote. The group urged Treasury to let states treat federal standards as a safe harbor when the statutory floor is unclear, rather than mandating that state regimes mirror federal implementing regulations line by line.
CSBS also flagged a timing concern: it characterized the state certification deadlines under the Act as "unrealistically short" and recommended a streamlined process where states can express intent to regulate stablecoin issuers rather than risk losing eligibility if they cannot meet initial deadlines.
On the other side, the Bank Policy Institute — representing the largest U.S. banks — argued in its comment letter that state-level oversight must be "as robust as the federal regulatory regime" to prevent harmful regulatory arbitrage. Banks have a direct competitive interest in ensuring that state-licensed non-bank issuers face equivalent compliance burdens.
The GENIUS Act's jurisdiction is structured around U.S.-domiciled issuers, which creates a structural asymmetry between the market's two largest stablecoins.
Circle, issuer of USDC, is headquartered in the United States and has positioned itself for PPSI designation since before the Act's passage. According to reporting from Crypto.news and BlockEden.xyz, USDC was "already compliant in substance" when the GENIUS Act was signed, requiring only the formal application process to achieve PPSI status. USDC's market capitalization has grown to approximately $78 billion, driven by institutional demand for regulated stablecoin exposure.
Tether, issuer of USDT, operates from El Salvador and sits outside the GENIUS Act's audit framework. Its $188 billion in outstanding supply represents the market's dominant settlement asset, but the new regulatory framework creates pressure at the margins. According to AO Trading's analysis, USDT supply contracted by approximately $3 billion in Q1 2026 — its first quarterly decline since 2022 — while USDC added roughly $2 billion in the same period.
Tether's response was the January 2026 launch of USAT, a U.S.-compliant stablecoin issued through Anchorage Digital Bank. However, USAT's market cap stood at approximately $20 million in early February 2026 — functionally negligible relative to either USDT or USDC.
The Act's prohibition on yield/interest payments has also drawn attention. A White House Council of Economic Advisers research paper published in April 2026 examined the effects of the stablecoin yield prohibition on bank lending, signaling that the administration views the no-yield rule as a deliberate policy choice to prevent stablecoins from competing with bank deposits for consumer savings.
The comment period has surfaced three distinct lobbying positions:
Banks (BPI, ABA, CBA, Financial Services Forum, The Clearing House): Want aggressive enforcement of the yield prohibition, including restrictions on indirect yield paid through affiliates or partners. Want state regimes held to federal standards to prevent regulatory arbitrage. Want robust AML/CFT requirements applied equally to issuers and digital asset service providers. Primary concern: non-bank issuers gaining competitive advantages through lighter regulation.
Crypto-native industry (Blockchain Association): Wants narrow statutory definitions — "Payment Stablecoins" should be construed strictly, with algorithmic or synthetic tokens excluded. Wants "Digital Asset Service Provider" interpreted narrowly to exclude protocol developers and liquidity providers. Supports the dual federal-state regulatory structure as enabling competition and innovation. Primary concern: overreach that captures DeFi infrastructure within BSA compliance obligations.
State regulators (CSBS): Want discretion to exceed federal minimums without being forced to adopt OCC-specific regulations. Want realistic certification timelines. Want stablecoin issuers prohibited from lending, yield-bearing programs, and financial services beyond those authorized by the Act, citing risk of "deposit flight from the banking system." Primary concern: federal preemption of state consumer protection authority.
The GENIUS Act represents the most comprehensive federal regulatory framework for digital assets enacted in the United States. Its implementation, however, is proceeding through a fragmented multi-agency process that has generated divergent proposals, competing stakeholder demands, and unresolved jurisdictional questions.
The June 9 comment deadline marks the close of the last major public input window before regulators begin drafting final rules. The July 18 finalization deadline leaves approximately six weeks for agencies to reconcile FDIC-OCC divergences, define the federal-state boundary, and build the AML/CFT enforcement apparatus that will treat stablecoin issuers as financial institutions for the first time.
For a $313 billion market that processes hundreds of billions in daily settlement volume, the stakes are structural. The rules that emerge from this process will determine whether U.S.-regulated stablecoins capture market share from offshore alternatives, whether state regulators retain operational authority, and whether the compliance cost of PPSI designation creates barriers to entry that consolidate the market around a small number of large issuers.
The data suggests the market is already adjusting: capital is migrating toward compliant issuers, offshore supply is contracting at the margin, and banks are positioning to enter a market that was previously the domain of crypto-native firms. Whether this regulatory framework accelerates or inhibits that transition depends on decisions that will be made in the next six weeks.
