The Federal Reserve Board on September 24 asked for public comment on two proposals that would start turning the GENIUS Act’s stablecoin statute into operating rules for firms under the Board’s supervision. One proposal would require full backing with specified reserve assets, set standardized capital requirements for credit and operational risk, add risk-management standards, create custody rules for reserve assets, and clarify which stablecoin-related activities are permissible for Board-supervised banks. The other would create a tailored approval process for a Board-supervised bank that wants to issue payment stablecoins.
Why it matters is less about crypto politics than payment infrastructure. The real business question is whether the Fed’s framework will make payment stablecoins dependable enough for mainstream payments and corporate treasury use, or whether the reserve, capital, custody, and approval gates will mainly favor large bank-linked issuers that can afford the compliance load.
From statute to gatekeeping system
The GENIUS Act, enacted on July 18, 2025, created a federal prudential framework for payment stablecoins designed to hold a stable value against a fixed reference amount, generally the U.S. dollar. It is not a blanket regime for every cryptoasset or tokenized product. The Fed’s proposals apply only to issuers and banks within the Board’s jurisdiction.
That distinction matters because the law itself set the broad assignment; regulators are now deciding how hard it will be to qualify as “safe enough for payments.” Under the statute, as the OCC said in its February 2026 bulletin, the framework takes effect on the earlier of 18 months after enactment or 120 days after the primary federal payment-stablecoin regulators issue final implementing regulations. The Fed is only one part of that larger build-out, and its September 24 announcement begins a rulemaking process rather than issuing a final rule or authorizing any bank to launch a token immediately. The 60-day comment clock starts after publication in the Federal Register.
The second proposal is especially important for market structure. A Board-supervised bank seeking to issue payment stablecoins would have to submit a business plan and financial information through a formal application path that includes appeals, hearings, and final determinations. That offers more procedural clarity than case-by-case improvisation, but it also creates an explicit entry gate.
How the control stack changes the business model
Stablecoins live or die on a simple promise: one token should redeem for one dollar, or whatever fixed amount the issuer promises. The Fed’s proposal is aimed at the machinery behind that promise.
Reserve-asset eligibility is the first layer. Full backing with permissible assets can reduce the risk that redemptions expose a shortfall, and it can make reserve portfolios easier to evaluate. For businesses considering stablecoins for payables, settlement, remittances, or cash management, that is a meaningful upgrade from a market where reserve practices can vary widely.
But full backing is not the same thing as frictionless redemption. It does not, by itself, prevent queues during stress, cyber incidents, legal disputes over access to reserves, or outages at the wallet, exchange, banking, or blockchain layer. That is why the proposal also reaches into capital, operational risk, and custody.
Standardized capital requirements for credit and operational risk could give issuers a thicker loss-absorbing buffer when something goes wrong outside the reserve pool itself. In practice, though, capital raises the cost of issuance. An issuer that must hold conservative reserves and additional capital has less room to compete on yield, fees, or growth-at-all-costs pricing.
Custody rules matter for the same reason. If reserve assets have to sit in supervised arrangements with tighter controls, the odds of commingling or sloppy reserve access should fall. But approved custody, reporting, controls, and legal review are not free. The likely effect is to make payment stablecoins look more like regulated balance-sheet products and less like lightweight software wrappers around dollar claims.
The proposal’s clarification of which stablecoin-related activities are permissible for Board-supervised banks could also shift competition. Clearer rules may encourage bank participation in issuance, reserve custody, or related services. That would give corporate users and payment partners a more familiar counterparty set. It could also make life harder for smaller issuers that lack a bank charter, a broad compliance staff, or cheap access to custody and liquidity infrastructure.
What businesses still do not know
The short public release outlines the architecture, but many of the terms that will determine commercial viability are still missing. It does not state the final numerical capital formula, reserve concentration limits, redemption service levels, treatment of uninsured deposits, custody segregation requirements, stress-testing expectations, fee structure, or the full operational-resilience standard.
Those omissions are not technical footnotes. They are where the economics live.
For a fintech issuer, the unanswered question is what the all-in cost of compliance will be once permitted reserves, capital charges, custody, and operational controls are modeled together. For a bank, the issue is whether the approval process and permissible-activity guidance create a workable product line or a niche service with too much supervisory friction. For corporate treasury teams, the practical question is whether a regulated stablecoin will behave like reliable short-duration cash infrastructure during stress, not just during normal hours.
That means treasurers and payment managers should treat this comment period as more than Washington process. They need to map which regulator would oversee their issuer or custodian, model the opportunity cost of permitted reserves and capital, test how redemption would work under heavy demand, verify wallet and custody controls, and define who owns sanctions screening, AML monitoring, outage response, customer support, disclosures, and wind-down responsibilities.
The coordination problem is still open, too. The release does not yet explain how the Fed’s framework will mesh with OCC rules, Treasury requirements, state oversight, foreign regimes, sanctions obligations, Bank Secrecy Act requirements, or cross-border supervision. On the same day, Governor Michael Barr said he supports the proposal but wants more work, including on the standard for supervisory or enforcement action related to anti-money-laundering deficiencies. That is a reminder that the hardest implementation questions are often not about reserves alone.
On the limited public detail now available, the direction is clear even if the thresholds are not. The Fed is trying to define a supervised payment product, not simply endorse stablecoins in the abstract. That could make the market more credible for banks, merchants, remittance providers, and corporate users. It could also leave the field dominated by institutions large enough to absorb fixed compliance costs. The coming fight in comments is over where that line should sit: broad enough to create a real payment rail, or narrow enough that scale and bank supervision become the main moat.
