The U.S. Treasury’s first rulemaking cycle under the GENIUS Act is doing more than filling in compliance details. It is redrawing who gets to issue dollar-backed stablecoins at national scale, under what reserve model, and with which regulator in charge. That matters because the law signed on July 18, 2025 did not simply bless stablecoins. It created a gated market structure. Treasury now sits at the center of foreign issuer access, sanctions coordination, and the practical boundary between crypto-native issuers and regulated financial institutions.
The first federal stablecoin framework is already narrowing the field
The starting point is not speculation. It is statute. President Donald Trump signed the GENIUS Act into law on July 18, 2025, creating what the White House described as the first-ever federal regulatory system for stablecoins. The White House fact sheet says the law requires 100% reserve backing with liquid assets such as U.S. dollars and short-term Treasuries, plus monthly public disclosure of reserve composition. That same fact sheet also says issuers are explicitly subject to Bank Secrecy Act obligations and Treasury-linked sanctions enforcement. Those are not side provisions. They are the control levers.
The legal text makes the market design even clearer. Under Section 4, permitted payment stablecoin issuers must maintain reserves on at least a 1:1 basis. Eligible reserves include U.S. currency, balances at a Federal Reserve Bank, demand deposits, Treasury bills, notes, or bonds with remaining maturity of 93 days or less, overnight repos backed by Treasury bills with 93 days or less to maturity, and certain reverse repos. Tokenized forms of those reserves can also qualify if they comply with applicable law. In plain English, scale is no longer about who can mint the most tokens. It is about who can warehouse compliant short-duration dollar liquidity and survive federal supervision.
That is the real shift competitors often miss. The GENIUS framework does not just regulate stablecoins. It industrializes them. Once reserve assets are restricted to cash-like instruments and very short-dated Treasuries, the advantage moves toward firms with treasury management capacity, bank relationships, operational controls, and audited disclosure systems. Smaller issuers can still exist. But scale economics now favor institutions that can run a balance sheet like a narrow payments utility rather than a growth-stage crypto platform. That is a structural power transfer.
Treasury’s role is not symbolic. It decides market access at the edges
The title of this story points to Treasury for a reason. The law gives multiple regulators a role, but Treasury controls some of the most strategic choke points. Wilson Sonsini’s post-enactment review notes that, unless otherwise stated, required rules under the Act must be promulgated no later than July 2026. It also highlights a critical foreign issuer provision: for a non-U.S. payment stablecoin issuer to issue in the United States, the Secretary of the Treasury, in consultation with the Stablecoin Certification Review Committee, must determine that the issuer’s home-country regime is comparable to the U.S. framework. Treasury must also maintain a public list of approved foreign jurisdictions.
That means Treasury is not merely writing technical standards. It is deciding which offshore stablecoin regimes are acceptable gateways into the U.S. market. If a foreign issuer’s home framework is not deemed comparable, access narrows. If it is approved, that issuer gains a path into the deepest dollar market in the world. This is where control at scale gets redrawn most visibly: not only between crypto and banks, but between domestic and foreign stablecoin blocs.
The timeline matters too. Treasury’s March 2026 report to Congress states that, in line with the GENIUS Act, Treasury issued a public request for comment on August 18, 2025 to identify innovative tools and strategies for detecting illicit activity involving digital assets. That report confirms Treasury moved quickly from enactment to implementation. The agency is not waiting for the market to settle itself. It is building the surveillance, AML, and sanctions architecture that issuers will have to plug into if they want legitimacy and scale.
Who gains power under the GENIUS model
Three groups come out stronger.
First, federally supervised issuers and bank-linked entities. The law creates a licensing regime for permitted payment stablecoin issuers, and the practical burden of reserve management, liquidity controls, and monthly disclosures fits institutions that already operate inside regulated finance. Skadden noted on July 17, 2025 that companies should assess their eligibility as permitted issuers, which says a lot by itself: eligibility, not just innovation, is now the threshold question.
Second, large incumbents with Treasury-bill scale. The reserve menu is short-duration and operationally demanding. Managing billions in 93-day-or-less Treasuries, overnight repo, and cash equivalents is easier for firms with mature treasury desks and established custodial infrastructure than for decentralized or lightly staffed issuers. The White House also framed the law as a source of increased demand for U.S. debt, which reinforces the idea that stablecoin growth is being tied directly to Treasury market plumbing.
Third, Treasury itself. The department gains more than visibility. It gains coordination authority over sanctions enforcement, a formal role in illicit-finance rulemaking, and a gatekeeping function for foreign comparability. In policy terms, that is a major centralization of influence over a sector that once marketed itself as disintermediated.
Who loses leverage as the rules harden
The losers are not only obvious bad actors. The framework also pressures business models that relied on ambiguity.
Unregulated or loosely regulated issuers lose room to operate because the law sets a federal baseline for reserves, redemption policy disclosure, and compliance. The Skadden analysis says the Act takes effect on the earlier of 18 months after enactment or 120 days after final implementing regulations are issued. It also notes that, in general, prohibitions on digital asset service providers offering or selling non-permitted payment stablecoins begin three years after enactment, subject to any Treasury safe harbor. That creates a countdown. Distribution channels will increasingly prefer compliant issuers long before the final deadline arrives.
Large nonfinancial public companies also face friction. Wilson Sonsini notes that public companies not predominantly engaged in financial activities must obtain unanimous approval from the Stablecoin Certification Review Committee before issuing a payment stablecoin. That is a high bar. It suggests Washington is willing to allow stablecoins to scale, but not to let every consumer-tech giant turn deposits, payments, and token issuance into one vertically integrated empire without extra scrutiny.
That point is central to the “who controls stablecoins at scale” question. The GENIUS framework does not hand the market to Big Tech by default. It channels power toward regulated financial operators and toward the federal agencies that can certify, deny, or condition access.
The overlooked angle: this is a market-structure law disguised as a crypto law
Most coverage has focused on consumer protection, reserve backing, or crypto legitimacy. Those are important, but incomplete. The deeper story is market structure. By limiting eligible reserves to cash, Fed balances, insured deposits, and very short-dated Treasuries or Treasury-backed overnight funding, the law compresses stablecoin design into a narrow operational template. By requiring monthly reserve disclosures and BSA compliance, it raises fixed costs. By giving Treasury a comparability role for foreign issuers, it turns cross-border stablecoin competition into a supervised access regime.
That combination changes control in three layers at once. Historically, stablecoin power sat with issuers that could win distribution and maintain market confidence. Comparatively, the GENIUS model shifts power toward issuers that can satisfy bank-grade liquidity, reporting, and compliance expectations. In significance, it means the next dominant stablecoin issuers may look less like offshore crypto utilities and more like regulated dollar infrastructure firms.
There is also a geopolitical layer. Treasury’s foreign comparability process effectively exports U.S. standards. If overseas jurisdictions want their issuers to access U.S. users at scale, they will need frameworks Treasury can recognize as comparable. That is not just domestic regulation. It is regulatory statecraft through stablecoin market access.
Conclusion
The first GENIUS rulemaking phase is not a routine implementation exercise. It is the mechanism through which stablecoin control is being reassigned. The law signed on July 18, 2025 established the framework. Treasury’s follow-on actions, including the August 18, 2025 request for comment and the broader rulemaking path due by July 2026, are defining who can actually use that framework to scale. The winners are likely to be issuers with compliant reserve operations, strong AML systems, and regulator-ready governance. The losers are firms that depended on opacity, jurisdictional arbitrage, or the assumption that distribution alone would secure dominance. In that sense, the first GENIUS rule does not just regulate stablecoins. It decides which institutions get to become the next layer of dollar infrastructure.
Frequently Asked Questions
What is the GENIUS Act?
The GENIUS Act is a U.S. federal law signed on July 18, 2025 that creates a national regulatory framework for payment stablecoins. It requires 100% reserve backing with liquid assets, monthly reserve disclosures, and compliance with anti-money-laundering and sanctions rules.
Why is Treasury so important under the new framework?
Treasury is central because it coordinates illicit-finance policy, has a sanctions-related role, and must determine whether foreign stablecoin regulatory regimes are comparable enough for issuers from those jurisdictions to operate in the U.S. market.
What reserves can compliant stablecoin issuers hold?
Under the statutory text, eligible reserves include U.S. currency, balances at a Federal Reserve Bank, certain demand deposits, Treasury securities with 93 days or less remaining maturity, and specified overnight repo or reverse repo arrangements backed by Treasuries.
Does the law favor banks over crypto-native issuers?
It does not explicitly exclude crypto-native firms, but it favors issuers that can manage short-duration reserves, disclosures, liquidity controls, and compliance at institutional scale. In practice, that gives bank-linked and heavily regulated operators an advantage. This is an inference based on the law’s reserve, licensing, and compliance design.
When do the key rules take effect?
According to legal analyses of the enacted law, the Act generally takes effect on the earlier of 18 months after enactment or 120 days after final implementing regulations are issued. Many required rules were expected no later than July 2026.
