Fed Proposes 1:1 Reserve Backing and Capital Rules for Stablecoin Issuers Under GENIUS Act

Writer Published Updated 0 comments

The Fed's September 24 proposals turn the year-old GENIUS Act from law into an operating rulebook — full reserves, a two-day redemption clock, and capital surcharges for issuers. What to watch: the 60-day comment window before final rules ahead of January 2027 enforcement.

September 25, 2026 — The U.S. Federal Reserve on September 24 proposed sweeping rules for payment stablecoin issuers it supervises, including 1:1 reserve backing, redemption within two business days, and layered capital charges. The proposals are the first concrete Fed rulebook under the GENIUS Act, the federal stablecoin law signed on July 18, 2025.

Editor's Highlight: This is the first time the GENIUS Act gets teeth. The law's 1:1 mandate becomes a specific reserve list, a two-day redemption standard, and capital charges — plus a defined path for banks to launch their own stablecoins.

What the Fed proposed on September 24

The Fed's Board of Governors in Washington, D.C. requested public comment on two notices of proposed rulemaking that would establish reserve, capital, risk-management, redemption, and bank-approval rules for Board-supervised payment stablecoin issuers under the GENIUS Act.

The comment period runs 60 days after the proposals are published in the Federal Register. The Fed has not set a calendar closing date — the clock starts at publication, not announcement.

Newsroom Focus: The Fed is writing the operating manual for a law that turns one year old next month. Issuers have known the principles since July 2025; now they are getting the exact numbers.

The 1:1 reserve rule and the two-day redemption clock

Every outstanding stablecoin must be backed 1:1 by permissible reserve assets. The Fed's list is narrow and conservative: U.S. dollars, Federal Reserve balances, insured deposits, U.S. Treasuries maturing within 93 days, and certain Treasury-backed repurchase agreements.

Issuers must also publish redemption policies and honor redemptions within no more than two business days. The proposal also sets rules for reserve custodians — the entities that actually hold the backing assets.

Analysis Note: The 93-day Treasury ceiling keeps reserves in the shortest, most liquid part of the market. Issuers cannot reach for yield with longer-dated paper — the rule trades profitability for safety.

Capital charges: the price of issuing

On top of reserves, the Fed proposes layered capital charges: a 2% credit-risk charge (applied to uninsured deposits and undercollateralized reverse repos, per Crypto Daily's read of the proposal) and an operational-risk charge of 1–2% of outstanding stablecoins, scaled by issuer size.

The layered design — reserves plus capital plus custodian rules plus a formal application process — raises compliance costs in ways that favor large, well-capitalized issuers and established banks over smaller or offshore players. That is arguably the point: the Fed wants stablecoins to behave like bank liabilities, with bank-like buffers.

A defined path for banks

The second proposal creates a tailored application process for insured state member banks to issue stablecoins through subsidiaries. Banks would submit business plans, financial information, capital-structure documents, and certifications — with defined appeals, hearings, and final-decision procedures.

Practical Takeaway: Banks now have a formal on-ramp. If the final rules land as proposed, expect the first wave of bank-issued stablecoins to follow the January 2027 enforcement date — the incumbents are being invited in.

From law to rulebook: the GENIUS Act timeline

The GENIUS Act — the federal payment-stablecoin framework — was signed on July 18, 2025, passing the Senate 68–30 and the House 308–122. It passed its one-year milestone on July 18, 2026.

Meanwhile, the follow-on Clarity Act has stalled: a cloture vote failed 49–50 on September 15, 2026, per The Crypto Times. Full GENIUS Act enforcement is expected in January 2027 — which makes the current 60-day comment window the last open door for issuers, banks, and consumer groups to shape the final rules.

Bottom Line

The Fed's proposals convert the GENIUS Act's 1:1 promise into hard numbers — specific reserves, a two-day redemption clock, and capital charges — with a bank on-ramp attached. What to watch: who files comments in the 60-day window, and how much of the draft survives to the January 2027 enforcement date.
