The Guiding and Establishing National Innovation for US Stablecoins Act's (GENIUS Act's) stablecoin framework will not be determined by what Congress wrote. It will be determined by 21 separate rulemakings from four federal agencies with different interpretive instincts and no shared enforcement mechanism for their deadline. Paradigm has built and published the first public tracker of this rulemaking landscape, revealing how fragmented the implementation process is. Agencies that move fastest and write the broadest rules will set the competitive terms for the US stablecoin market, regardless of what slower-moving counterparts decide. The risk is not inaction. The risk is incoherence across a multi-regulator system with no central arbiter.

Congress passed a mandate; the agencies will write the market

The GENIUS Act became law last summer as the first federal statute to establish a framework for payment stablecoins in the United States. It was, by that measure, a historic moment. But the statute is not the operative instrument. The operative instruments are the rules that will emerge from rulemaking under the Administrative Procedure Act (APA).

The APA process has three stages. An agency may begin with an Advance Notice of Proposed Rulemaking (ANPRM), an early request for input before any formal proposal is drafted. Many agencies skip this step. The core stage is the Notice of Proposed Rulemaking (NPRM), which puts a specific proposed rule out for public comment, typically for 30 to 60 days. Anyone can submit a comment: companies, universities, retail users, members of Congress. Agencies are legally required to consider what they receive. The Final Rule follows, sometimes months later, sometimes years, and includes an effective date when the requirements become binding. Until a Final Rule is published, issuers operate under uncertainty.

Four agencies share 21 rulemakings and one notional deadline

The GENIUS Act requires rulemakings from the Office of the Comptroller of the Currency (OCC), the National Credit Union Administration (NCUA), the Federal Deposit Insurance Corporation (FDIC), and the Federal Reserve Board (FRB). Paradigm's tracker counts 21 required rulemakings in total across these four agencies. Federal agencies have until July 18, 2026 to complete most of them. Full implementation takes effect January 18, 2027. Neither date carries a legal enforcement mechanism for non-compliance.

These four agencies have different institutional cultures, different relationships with their supervised institutions, and different mandates. The OCC supervises national banks and federally chartered non-bank entities. The NCUA supervises credit unions. The FDIC focuses on deposit insurance and bank resolution. The FRB supervises state-chartered banks that are members of the Federal Reserve System and bank holding companies. Nothing in the GENIUS Act requires these agencies to reach the same conclusions on shared questions.

The Dodd-Frank precedent indicates the deadline will slip

Paradigm raises the Dodd-Frank Act directly as a cautionary precedent. The Dodd-Frank Wall Street Reform and Consumer Protection Act, signed in 2010, mandated over 400 rulemakings. As of today, dozens remain incomplete. Some significant rules mandated by that statute have never been finalized. The GENIUS Act is a much smaller statute, but the structural dynamic is identical: Congressional deadlines for agency rulemaking are "important, but frequently aspirational," as Paradigm puts it, because there are no real consequences for agencies that miss them.

The July 18, 2026 deadline is 14 months from the Act's enactment. That is a compressed timeline for agencies managing competing regulatory priorities. The NCUA has published a first-round rulemaking. The OCC has published a proposed rule. Whether the FDIC and FRB complete their required rulemakings before the deadline is an open question, and the market will not wait for them to answer it.

Reserve rules and yield rules are the highest-stakes divergence points

Paradigm identifies three categories of GENIUS rulemakings as most consequential: reserve requirements and permissible backing assets, OCC charter eligibility, and yield-sharing with users and ecosystem participants. These three areas are also the most likely to produce interpretive divergence across agencies.

Consider reserve requirements. If the OCC and the FDIC reach different conclusions about what assets qualify as permissible reserves for stablecoin backing, issuers have a direct financial incentive to seek the supervisory charter whose rules are most favorable. That kind of charter shopping is not aberrant behavior. It is the rational response to a regulatory structure that creates a competitive spread between otherwise identical institutions operating under different supervisors.

The yield question creates a parallel incentive. The GENIUS Act includes a prohibition on issuers paying holders interest or yield solely in connection with holding or using a stablecoin. How agencies interpret and implement that prohibition varies. An OCC rule that interprets the prohibition broadly while a FDIC rule interprets it narrowly creates an asymmetry between OCC-supervised and FDIC-supervised issuers. Issuers will notice. So will investors choosing where to charter new stablecoin operations.

The July 18, 2026 deadline is the first structural test. Every Final Rule published before that date closes one source of uncertainty. Every rulemaking that carries only proposed rules past that date extends the period during which issuers in different regulatory lanes operate under different obligations. Paradigm's tracker, available at paradigm.xyz/genius, will update as rulemakings progress. The pattern of early compliers versus late ones will map the competitive asymmetries in real time.

The reserve and yield rulemakings deserve particular attention. The OCC has already proposed rules on yield; its Final Rule is expected before July 18, 2026. The FDIC has not yet published a comparable proposal. If the gap persists past the deadline, the period between July 2026 and the January 18, 2027 implementation date will be the window during which charter arbitrage is most visible and most consequential. Any issuer announcing a new supervisory charter application during that window deserves scrutiny about which regulatory regime it is choosing, and why.
