The US Treasury Department opened a 60-day public comment period on Monday for proposed rules implementing the GENIUS Act, arriving weeks after federal agencies collectively missed a July deadline that would have ensured finalized regulations before the law takes effect in January 2027.
Treasury Secretary Scott Bessent framed the late-stage rulemaking as an opportunity rather than a setback, stating that the department “welcomes input from stakeholders as [it works] to provide the regulatory certainty businesses need to innovate and grow in America.” The comment period begins counting from the date the proposed rule appears in the Federal Register.
The timing creates a peculiar regulatory situation. The Guiding and Establishing National Innovation for US Stablecoins Act, which President Trump signed into law in July 2025, was structured with two possible effective dates: either 120 days after agencies finalize their implementing rules, or 18 months after enactment, whichever comes first. Since no agency managed to finalize rules within the 120-day window that closed in July, the hard 18-month deadline of January 18, 2027 now governs.
That means the US stablecoin market, which involves tens of billions of dollars in assets like Tether and USDC, will operate under a new federal licensing requirement in roughly five months. Whether it will operate under clear, finalized compliance guidance is another question entirely.
The Regulatory Pileup Behind the Missed Deadline
The Treasury Department is not working alone on GENIUS Act implementation. The Office of the Comptroller of the Currency, the Federal Deposit Insurance Corporation, and the Federal Reserve Board have all issued their own notices of proposed rulemaking throughout 2026. Each agency handles different aspects of the regulatory framework depending on whether a stablecoin issuer is a national bank, a state-chartered depository institution, or a nonbank financial company.
The legislative structure anticipated this multi-agency coordination. Congress gave regulators what appeared to be a reasonable runway: publish implementing rules, accept comment, finalize, then trigger the 120-day countdown to effectiveness. Instead, all four agencies are still in the proposed-rule stage as of mid-August.
What went wrong? The short answer is that stablecoin regulation touches too many regulatory boundaries simultaneously. The Treasury’s rules address anti-money laundering compliance and sanctions screening. The OCC’s rules govern how national banks can custody and issue stablecoins. The FDIC’s rules determine whether stablecoin reserves held at insured banks qualify for pass-through deposit insurance. The Fed’s rules set capital and liquidity requirements for Fed-member banks engaging in stablecoin activities.
Each agency needed to coordinate with the others to avoid contradictory requirements, which slowed everyone down. The July 2025 enactment also occurred during a broader reshuffling of financial regulatory priorities under the Trump administration, with agencies simultaneously working on digital asset custody guidance, crypto broker rules, and SAB 121 implementation.
We covered the one-year anniversary of the GENIUS Act signing in GENIUS Act Anniversary: Stablecoin Rules Still Months Away, and the story then was essentially the same: agencies acknowledging they would miss their targets while expressing confidence that final rules would arrive eventually.
What the Treasury’s Proposed Rules Actually Require
The Treasury’s notice addresses its specific jurisdictional slice of GENIUS Act implementation. For our purposes on this site, and for anyone issuing or using stablecoins in the US, here’s what matters.
The core licensing mandate is straightforward. Once the GENIUS Act goes into effect, an entity generally may not “issue a payment stablecoin” in the United States without either a federal license (from the OCC for national trust banks) or a state license from a state that has adopted qualifying stablecoin regulations. The definition of “payment stablecoin” under the law covers dollar-denominated tokens designed to maintain a stable value relative to the dollar and used or designed for use as a medium of exchange.
That definition captures USDC, Tether, and most other dollar stablecoins. It likely captures algorithmic stablecoins too, though the proposed rules may clarify edge cases. It probably does not capture synthetic dollar products that don’t represent themselves as payment instruments (think yield-bearing DeFi positions that happen to track the dollar), though this boundary is exactly the kind of thing public comments might influence.
The Treasury’s proposal also covers anti-money laundering and sanctions compliance, requiring stablecoin issuers to implement know-your-customer procedures consistent with Bank Secrecy Act requirements. This is less novel than it sounds (Circle and Tether already maintain substantial compliance programs), but it formalizes what was previously a patchwork of voluntary practices and state-level requirements.
If you want to review the actual notice, the Treasury’s press release is available on the department’s website, though the full proposed rule text will appear in the Federal Register. Our GENIUS Act stablecoin regulation explainer covers the law’s structure in more detail for readers new to the topic.
The UK Comparison and International Coordination Angle
In July, the UK-US Financial Regulatory Working Group met in London to discuss cooperation between the two countries’ financial agencies. Implementation of the GENIUS Act was explicitly on the agenda, according to the Treasury’s announcement.
The meeting is interesting for what it reveals about the international competitive dynamics around stablecoin regulation. The UK has taken its own steps toward stablecoin oversight, but British crypto industry participants have reportedly argued that their country is falling behind the US now that GENIUS provides a clear federal framework.
The UK’s approach has been more incremental. The Financial Conduct Authority has proposed extending its regulatory perimeter to cover stablecoins used for payments, and the Bank of England has consulted on systemic stablecoin oversight. But no single comprehensive statute equivalent to GENIUS has emerged from Parliament.
This creates an unusual situation where US regulatory clarity (even incomplete clarity) may attract stablecoin issuers that previously preferred jurisdictions with lighter oversight. Circle, the issuer of USDC, is already a US-headquartered company with a New York BitLicense. Tether, headquartered in the British Virgin Islands, has historically avoided US regulatory engagement but may need to reconsider its position if GENIUS makes US market access contingent on licensing.
The UK-US working group discussions suggest both countries recognize the need for cross-border coordination. Stablecoins are inherently global instruments. A dollar stablecoin issued under a GENIUS license will still trade on exchanges worldwide, still settle transactions across borders, still interact with DeFi protocols that don’t recognize jurisdictional boundaries. Regulatory divergence creates opportunities for arbitrage and compliance gaps.
Whether the working group produces substantive harmonization or just diplomatic pleasantries remains to be seen. The January 2027 deadline applies only to US law, and the UK faces no equivalent forcing function.
Implications for Stablecoin Issuers and DeFi
The practical question for market participants is: what changes on January 18, 2027?
For major issuers like Circle, likely not much immediately. Circle has pursued regulatory compliance aggressively for years, holds state money transmitter licenses across the US, and would be a natural applicant for whatever federal licensing framework emerges. The company has the legal infrastructure to adapt to final rules quickly.
For Tether, the situation is more complex. Tether has historically kept its US exposure limited, preferring to serve markets outside direct US regulatory jurisdiction. The GENIUS Act’s licensing requirement applies to issuing stablecoins “in the United States,” and the precise boundaries of that geographic trigger matter enormously. Does a foreign issuer whose tokens trade on US exchanges need a license? What about tokens that US persons can access through DeFi protocols? The proposed rules may clarify these questions, or they may leave them ambiguous enough that enforcement discretion becomes the operative standard.
For DeFi protocols, the implications are even murkier. Many DeFi applications integrate stablecoins as core infrastructure: Aave lending markets, decentralized exchanges, and cross-chain bridges all depend on stablecoin liquidity. The GENIUS Act focuses on issuers rather than users or integrators, so DeFi protocols themselves probably don’t need licenses. But if unlicensed stablecoins become legally problematic, protocols face pressure to delist or deprioritize them.
The fear and greed dynamics of the broader crypto market may also respond to regulatory milestones. Regulatory clarity has historically been bullish for institutional adoption, since large financial players need legal certainty before allocating capital. A functioning GENIUS framework could accelerate the institutional adoption of stablecoin infrastructure in traditional finance applications.
The Path From Here to January
The Treasury’s 60-day comment period sets the immediate timeline. Interested parties, which include stablecoin issuers, crypto exchanges, banks considering stablecoin activities, and industry advocacy groups, can submit comments explaining what they like, what they hate, and what they want changed.
Then Treasury has to actually read those comments and decide which ones merit changes to the proposed rules. This is not a rubber-stamp process. Agencies frequently modify proposed rules in response to public comment, especially when commenters identify practical implementation problems the agency overlooked. The Administrative Procedure Act requires agencies to respond to significant comments, so substantive engagement by the industry creates a paper trail the agency must address.
Meanwhile, the OCC, FDIC, and Fed are running their own parallel processes. Each agency has its own comment period, its own internal review, and its own finalization timeline. Coordinating four agencies to produce a coherent regulatory framework is difficult even without deadline pressure.
The most likely scenario is that some rules are finalized before January 18, while others remain in proposed form. Issuers would then face the uncomfortable position of needing licenses to operate legally, without complete certainty about what licensed operation requires.
This is not unprecedented. Financial regulation frequently operates in gray zones where agencies have issued guidance without formal rules, or where rules exist but enforcement priorities have not been articulated. The crypto industry has complained loudly about regulation-by-enforcement for years; GENIUS was supposed to fix that problem by providing clear statutory authority. Incomplete implementing rules undermine that goal without entirely negating it.
Wise, the UK payments company, recently announced it would resubmit its US bank charter application under the GENIUS Act framework after the OCC previously rejected its application on AML compliance grounds. We covered that pivot in Wise Pivots to GENIUS Act Framework After OCC Rejects Bank Charter, and it illustrates how companies are already treating GENIUS as the governing standard even before final rules exist.
What Industry Observers Are Watching
Several specific questions will likely dominate the public comment period and subsequent finalization process.
First, reserve requirements. The GENIUS Act requires payment stablecoin issuers to maintain reserves backing their tokens, but the precise composition of acceptable reserves is left to regulatory discretion. Can issuers hold Treasury bills? Money market funds? Bank deposits? The answer affects yield economics and, by extension, whether stablecoin issuance remains profitable.
Second, audit and disclosure requirements. How frequently must issuers prove their reserves? What level of attestation is required, and from whom? Circle has voluntarily published monthly reserve attestations from Grant Thornton; Tether’s disclosure practices have been more controversial. Final rules could standardize expectations across the industry.
Third, interoperability with state regimes. The GENIUS Act contemplates a dual federal-state framework where issuers can choose federal licensing through the OCC or state licensing through compliant state regimes. Which states qualify? How do state and federal requirements interact? The answers affect where companies choose to incorporate and seek licenses.
Fourth, treatment of decentralized stablecoins. The GENIUS Act’s licensing requirement applies to “issuers,” but some stablecoins (like DAI) are issued through decentralized protocols without a single controlling entity. Does anyone need a license for a truly decentralized stablecoin? Can such a thing even exist under a licensing regime?
These questions won’t all be answered by January. But the comment period is the industry’s best opportunity to influence the answers before they crystallize into binding law.
The Broader Regulatory Context
The GENIUS Act implementation is happening alongside other significant crypto regulatory developments. The CLARITY Act, which would establish a framework for distinguishing securities from non-securities in crypto markets, remains pending in Congress with an uncertain path forward. The CFTC has been active on derivatives oversight, recently seeking public input on AI compute futures contracts. The SEC continues grappling with enforcement priorities and Reg D questions around token launches.
For stablecoins specifically, the competitive landscape is shifting. USDC has gained market share relative to Tether in recent months, partly because Circle’s regulatory posture is seen as more compatible with institutional requirements. If GENIUS tilts the playing field further toward compliant issuers, that trend may accelerate.
The market dynamics of stablecoin usage are also evolving. Stablecoins increasingly serve as settlement infrastructure for traditional financial applications, not just crypto trading. Tokenized Treasury funds like those from Spiko (which we covered in Spiko Becomes First UCITS Fund Manager to Accept Stablecoin Payments) accept USDC for subscriptions and redemptions. If GENIUS establishes stablecoins as regulated financial instruments, their integration into traditional finance may accelerate further.
The January 2027 deadline is artificial in some sense. Nothing magical happens on that date other than the statute taking legal effect. But artificial deadlines have real consequences. They force agencies to publish something, force issuers to adapt to whatever emerges, and force markets to price in regulatory uncertainty.
Whether the Treasury and its peer agencies can produce workable rules in the remaining months is genuinely uncertain. The comment period that opened Monday is one of the last major checkpoints before the answer becomes clear.
