How is this rulemaking proposal different from the GENIUS Act itself? Wasn't the law already signed back in 2025?
When the GENIUS Act was signed in July 2025, the statutory text itself used principle-based language like "high-quality liquid assets" and "adequate capital," without spelling out specific numbers — this is standard legislative practice, where the underlying law sets direction and framework, and the actual operational thresholds get filled in through a subsequent rulemaking process, with rulemaking authority distributed across the agencies the statute designates. This September 2026 proposal is the Fed exercising its GENIUS Act authority to concretely define "high-quality liquid assets" as "Treasuries maturing within 93 days, cash, or insured bank deposits," and "adequate capital" as "2% capital on the first $20 billion issued." Until this proposal is finalized, the industry could only guess at these thresholds based on informal norms; once finalized (expected as early as late 2026 or early 2027), they become legally binding requirements, with violations constituting a federal compliance breach.
How much actual impact will the 93-day Treasury cap have on issuers' real reserve allocations?
The impact depends on an issuer's existing allocation habits. Major issuers with a long track record of public disclosure, like Circle, have historically reported Treasury holdings already skewed toward extremely short maturities — most within 90 days — since short-dated Treasuries offer the highest liquidity and lowest interest-rate sensitivity, which is already standard risk-management practice in the industry. For these issuers, the 93-day cap essentially codifies existing practice into formal rule, and the actual portfolio adjustment required may be quite limited. But for smaller issuers, or newer applicants still building out a full reserve-management function, if they'd previously reached for six-month or even one-year Treasuries to capture extra yield in a low-rate environment, this rule would force a shorter maturity structure and could disrupt whatever yield model they'd built around it — which is exactly why industry groups are expected to push back during the 60-day comment period on whether the 93-day cap is too rigid.
What's the connection between Fed Governor Michael Barr's mention of an "AML compliance gap" and this round of capital and reserve rules?
Strictly speaking, the two proposals released this round primarily address reserve assets, capital levels, and redemption timing — not AML compliance directly. The AML gap remains a separate, still-unresolved issue that this particular rulemaking round doesn't fully address. But there's an indirect connection: the 48-hour redemption window rule addresses the first of Barr's two concerns — the structural resemblance between stablecoins and a traditional bank run — by forcing a hard time limit that reduces the odds an issuer could cite "processing" to stall redemptions and trigger a panic-driven run. The AML gap concern is expected to be addressed separately in a subsequent rulemaking round by the Fed or another agency — which is exactly why it matters to understand that GENIUS Act implementation is a multi-round rulemaking process, not a single event; these two proposals are just one stage of it.
If industry lobbying succeeds in adjusting the thresholds during the 60-day comment period, what should everyday users pay attention to?
The comment period is a standard step in U.S. federal notice-and-comment rulemaking — industry groups pushing back on the 2% capital threshold or 93-day cap is exactly the kind of interaction this process is designed to produce, and doesn't mean the rulemaking itself has failed or been hollowed out. What's actually worth watching is whether the final version loosens or tightens these two numbers, and whether the redemption-window rule survives unchanged. For everyday holders, rather than tracking the political back-and-forth of the comment period closely, a more practical approach is to keep watching whether the stablecoins you actually hold start disclosing Treasury maturity distributions in their reserve reports once the rule takes formal effect — if an issuer keeps declining to disclose that level of detail even after the rule is finalized and in force, that's worth treating as a warning sign in its own right.
On September 24, 2026, the Federal Reserve released two rulemaking proposals under the GENIUS Act — the first time since the law's signing in July 2025 that a federal regulator has translated "high-quality liquid assets" and "adequate capital" from abstract statutory language into actual numbers. For over a year, the industry had been guessing at what those phrases would mean in practice. Now there's an answer: Treasury holdings in reserves can't exceed 93 days to maturity, rehypothecation of reserve assets is prohibited, issuers must hold a 2% capital buffer against the first $20 billion of stablecoins issued, and redemption requests must be processed within 48 hours. The public comment period closes October 19, and the OCC has separately signaled it's targeting November 2026 to finalize its own portion of the framework.
The first proposal targets reserve assets and capital requirements. "Fully backed one-to-one" gets a concrete definition: reserves must consist of high-quality liquid assets — short-dated U.S. Treasuries, cash, or insured bank deposits — with a maturity cap of 93 days, specifically to stop issuers from reaching for extra yield by holding longer-dated, less liquid, more volatile bonds. If a genuine mass redemption event hits, anything maturing within 93 days can simply run off at maturity without needing a discounted fire sale on the secondary market. The rehypothecation ban, meanwhile, closes off the practice of issuers borrowing against the very reserves backing their stablecoins and reinvesting the borrowed funds for extra yield — long one of the biggest sources of outside suspicion about whether reserves were quietly being put to other uses. The second proposal covers the approval process for banks or institutions applying to become stablecoin issuers, including specific customer identification requirements, and dovetails with the approval framework the OCC is advancing in parallel.
The "2% capital on the first $20 billion issued" figure sits in a completely different category from the OCC's earlier $5 million minimum capital requirement for newly chartered issuers — the OCC's number is an entry bar, while the Fed's 2% is a scaling capital buffer that grows proportionally with issuance size, meaning the absolute dollar amount required rises as an issuer gets bigger. For an institution issuing $10 billion in stablecoins, 2% works out to a $200 million capital reserve — money that isn't meant to fund everyday redemptions (those should already be covered by equivalent reserve assets) but instead absorbs operational risk, legal risk, or an unexpected shortfall in reserve asset value, so losses don't get passed straight through to holders. The Treasury Department already published its own portion of the proposed rules back on August 18; the Fed's move this week effectively fills in a critical missing piece of the GENIUS Act's three-agency regulatory puzzle — Treasury, the Fed, and the OCC.
A hard 48-hour redemption deadline isn't itself a surprise — the GENIUS Act's statutory language already gestured in that direction — but it lands differently read alongside warnings Fed Governor Michael Barr raised publicly earlier this year. Barr flagged two specific concerns: first, that stablecoins still carry structural risk resembling a traditional bank run, and second, that the AML compliance gap remains unresolved. The 48-hour window is aimed squarely at the first concern. Without an explicit ceiling, an issuer could in theory cite "processing" as a reason to delay redemption indefinitely — exactly the moment where panic first set in during the multiple stablecoin confidence crises of 2022 and 2023. Writing the redemption deadline into federal rule, rather than leaving it to an issuer's own voluntary commitment, turns it from "whatever the issuer says" into "a federal requirement, violated at the issuer's own risk."
For major operating issuers like Circle and Paxos, whose publicly disclosed reserve composition already skews toward short-dated Treasuries, the actual adjustment forced by the 93-day cap is likely modest. For newer applicants still finalizing their reserve allocation strategy, though, this rule draws a hard boundary around what's operationally permissible — no longer a gray area to be worked out later. For everyday holders, the most immediate takeaway from this rulemaking round is that evaluating whether a stablecoin's reserves are "actually safe" no longer stops at whether it's been audited — you can now also ask whether its Treasury holdings' maturity distribution respects the 93-day cap, and whether there's any evidence of rehypothecation. Details that used to be legible only to insiders will gradually become standard disclosure items, simply because a federal rule now exists requiring them. During the 60-day comment period, industry groups are expected to push back on whether the 2% capital threshold runs too high and whether the 93-day cap is too rigid, so the final version could still shift — but the underlying direction, turning "adequate reserves" from an abstract phrase into an auditable number, is now essentially set.
