KEY POINTS
- The FDIC approved a prudential framework for supervised banks issuing or custodianizing payment stablecoins: reserves, redemption, capital, and risk management standards.
- The agency ruled definitively that payment stablecoins backed by FDIC-insured reserves do not qualify for pass-through deposit insurance — contradicting GENIUS Act language that prohibits representing stablecoins as insured.
- The 60-day comment period opens with the proposal’s Federal Register publication; the GENIUS Act’s July 18, 2026 implementation deadline is driving urgency.
On April 7, 2026, the FDIC Board of Directors approved a sweeping notice of proposed rulemaking that establishes the prudential backbone for how its supervised banks will handle payment stablecoins under the GENIUS Act. The proposal covers reserve asset requirements, mandatory redemption windows, minimum capital floors, and risk management standards for both dedicated stablecoin issuers and banks offering custodial services for stablecoin reserves.
This is the FDIC’s second GENIUS Act rulemaking — the first, approved in December 2025, set up the application process for banks seeking to issue payment stablecoins through a subsidiary.
The GENIUS Act, signed into law on July 18, 2025, set a July 18, 2026 deadline for federal regulators to publish implementing rules — or the law kicks in automatically 18 months after enactment. According to the Federal Register, primary federal regulators must each promulgate rules by that date or lose the ability to shape how their supervised institutions operate in the stablecoin space. The FDIC’s proposal gives the industry 60 days to comment once it publishes in the Federal Register.
The stakes are enormous. The combined stablecoin market — anchored by Tether (USDT) at roughly $180 billion and Circle’s USDC — now underpins a substantial portion of on-chain economic activity. Getting the rules wrong could either strangle that infrastructure or leave the Deposit Insurance Fund exposed to risks it was never designed to bear.
A Framework Banks Can Actually Work With
The FDIC’s proposal lays out a four-pillar prudential framework for its supervised permitted payment stablecoin issuers: reserves, redemption, capital, and risk management. Each pillar has teeth. Reserves must be held in high-quality, liquid assets — cash, Fed deposits, short-term Treasuries, or overnight repos backed by Treasuries.
Redemption requirements ensure users can get their money back on demand. Capital floors guard against operational failure. Risk management standards force issuers to treat stablecoin operations as the material business line they are, not a side experiment.
For insured depository institutions providing stablecoin custody and safekeeping services, the proposal is equally clear: you play by these rules or you don’t touch the business. The FDIC is not leaving room for banks to offer stablecoin-related services outside this framework.
The proposal also resolves a question that has lingered since the GENIUS Act’s passage: how tokenized deposits fit under existing deposit insurance law. According to the FDIC’s press release, tokenized deposits that satisfy the statutory definition of a “deposit” receive the same treatment as any other deposit under the Federal Deposit Insurance Act — no special treatment, no special risk. That clarity alone will unblock product development at banks that had been sitting on tokenization plans waiting for exactly this signal.

No Pass-Through Insurance — Full Stop
Here is the line the industry did not want to hear: the FDIC plans to propose that payment stablecoins backed by FDIC-insured reserves do not qualify for pass-through deposit insurance. FDIC Chairman Travis Hill outlined the position at the American Bankers Association Washington Summit on March 11, 2026, and the April 7 proposal carries it forward formally.
Pass-through deposit insurance is an old and well-established mechanism. Broker-dealers, fintechs, prepaid card networks, and deposit placement networks all use it today — the FDIC insures the end-customer’s deposit, not the intermediary’s. The GENIUS Act is silent on whether that framework could apply to stablecoins. Hill argued it cannot, and the FDIC’s proposal agrees.
The reasoning cuts both legally and operationally. Legally, treating stablecoin holders as insured depositors on a pass-through basis flatly contradicts the GENIUS Act’s explicit prohibition on representing that stablecoins are “subject to Federal deposit insurance.” You cannot have it both ways — a stablecoin cannot simultaneously be marketed as uninsured and as an access point for FDIC coverage.
As Hill stated in his March speech, the Act’s firm prohibition only makes sense if Congress never intended stablecoins to be deposit products in the first place.
Operationally, the mechanism breaks down differently. Traditional pass-through insurance works because money moves — customers withdraw, funds leave the account. With stablecoins, the stablecoins move on-chain while the underlying reserves sit stationary at the bank. The FDIC sees that as a structural mismatch, not a technicality.
The implications for banks are concrete. If a bank holding stablecoin reserves fails, the reserves are an asset of the failed institution — not an insured deposit belonging to stablecoin holders. Stablecoin issuers and their users bear that risk directly, just as the GENIUS Act intended. Hill framed it plainly: the question should be settled by regulation before a bank fails and different parties show up with different expectations.
What Happens Next
The 60-day comment period opens as soon as the proposal hits the Federal Register. Banks, stablecoin issuers, custody providers, and the broader crypto industry will all have submissions. The pass-through insurance question is likely to generate the most controversy — Hill acknowledged the FDIC is “particularly interested in comments on this aspect” — but the capital and reserve requirements will draw intense scrutiny from banks weighing whether the stablecoin business is worth the compliance burden.
For the major stablecoin operators — Tether at $180 billion and counting, Circle’s USDC — this rulemaking is the regulatory scaffolding they have been waiting for. As we reported recently, Tether is pushing for a funding round that values the company at $500 billion, a number that only makes sense in a world where stablecoins have a clear, bank-grade regulatory home. The FDIC’s framework is that home. Whether banks choose to build inside it is the next question.
The GENIUS Act is coming. Banks that want a seat at the stablecoin table need to be in the comment period now — not reading about it later.
