GENIUS Act Stablecoin Rules: A Plain-English Walkthrough

What the GENIUS Act actually is, and why it exists

The Guiding and Establishing National Innovation for US Stablecoins, or GENIUS Act, is the first US federal statute written specifically for dollar-pegged payment stablecoins. Before it passed, a stablecoin issuer in the US had to stitch together a money-transmission license in each state it served, plus a patchwork of state money-transmitter rules, federal money service business registration with FinCEN, and an unresolved debate about whether its token was an unregistered security under SEC rules.

The Act carves out a new legal category, the "payment stablecoin," defined narrowly as a digital asset issued on a blockchain, pegged to a fixed value (in practice, the US dollar), backed by eligible reserve assets, and redeemable by the holder at par. It does not cover algorithmic stablecoins, tokenized money market funds, or CBDCs. Those stay under existing or future rules.

The political driver was straightforward. Tether (USDT) and Circle (USDC) move tens of billions of dollars a day, most of it outside the US, with no federal supervisor in the same sense a US bank has one. Lawmakers wanted a domestic framework that pushed issuance onshore, set reserve and audit standards, and gave regulators clear authority without killing the product. The Act passed with bipartisan support on that logic.

The risks a stablecoin user still faces under the new rules

Before the mechanics, the honest picture of what can still go wrong. The GENIUS Act is a real improvement over the previous patchwork, but it is not deposit insurance, and it does not eliminate the structural risks of holding a stablecoin.

First, reserve composition risk. The Act requires 100% backing in cash, balances at the Federal Reserve, and Treasuries with maturity of 90 days or less. That is tighter than the rules most issuers already followed, and it is audited. But it is not the same as FDIC coverage. If Circle, Tether, or any other issuer becomes insolvent because of fraud, an operational failure, or a bank run that exhausts liquidity, holders are general unsecured creditors of that company. They stand in line alongside employees and trade creditors, ahead of equity holders but behind any secured lender. They do not get the $250,000 per depositor insurance that a checking account at a US bank gets.

Second, redemption friction. The Act guarantees the right of redemption at par, but it does not guarantee instant redemption 24/7 under all conditions. Issuers can set cut-off times, minimums, and KYC requirements. During the March 2023 USDC depeg, holders could redeem, but only through banking channels that themselves were clogged. The law does not change the fact that on-chain liquidity depends on market makers willing to absorb the redemption flow.

Third, regulatory transition risk. Existing issuers like USDT and newer entrants like USD1, PYUSD, and RLUSD must decide whether to become federally chartered, stay under state regimes that are deemed compliant, or exit the US market. That transition creates uncertainty about which tokens remain fully redeemable for US persons in the next 12 to 24 months, and at what fee.

Fourth, smart-contract and custody risk. The Act governs the issuer, not the underlying blockchain or wallet. A bug in the ERC-20 contract, a private-key compromise at a custodian, or a sanctions event on a particular address can lock funds even when the issuer itself is fully solvent. The law does not insure against any of these.

The 100% reserve and short-term Treasuries requirement

The headline rule is simple: every payment stablecoin issued under the Act must be backed dollar-for-dollar by eligible assets, defined as US dollars, deposits at a Federal Reserve Bank, or Treasuries with remaining maturity of 90 days or less, plus repurchase agreements collateralized by those same instruments. Money market funds, commercial paper, corporate bonds, equities, crypto, and foreign sovereign debt are out.

This is a meaningful tightening. Tether's reserves historically included a slice of secured loans, precious metals, and other non-Treasury assets, and only moved toward majority Treasuries after repeated public pressure. Circle already held the bulk of USDC reserves in short-dated Treasuries and cash equivalents, which is one reason it is widely seen as the most naturally compliant incumbent. Under the Act, every covered issuer has to operate at the standard Circle already does.

Two details that get missed. First, the reserve assets must be segregated from the issuer's operating funds, so they cannot be tapped to pay an issuer's other creditors in an insolvency. Second, issuers must publish monthly reserve attestations from a qualified accounting firm and undergo an annual audit. That does not make reserves risk-free, but it does make silent fractional backing harder to sustain.

What the rule does not do is eliminate mark-to-market risk on the Treasuries themselves. A 90-day T-bill is among the safest assets in the world, but its price still moves with rates, and in a worst-case scenario where the Fed has to defend the short end, those prices can gap. For a 1:1 issuer, the question is whether reserves plus a small capital buffer can absorb that without breaking the peg. The Act requires a capital buffer; it does not specify its size, leaving that to OCC and state regulators to set.

Why "no yield passthrough" is the most contested line in the Act

Section 4 of the Act, in plain English, says a payment stablecoin cannot pay interest, yield, or any return to the holder based on holding the token. The intent is to draw a clean line between stablecoins, which the Act treats as a payment instrument, and securities or deposits, which already have their own regulators.

The line is harder to draw in practice. Several issuers already pay what looks like yield, structured to fit inside or around existing rules. Coinbase, through its USDC rewards program, has historically passed a share of reserve income back to holders, framed as a rewards program rather than interest. Gemini ran a similar program before suspending it. Tether has invested part of its treasury in Bitcoin and gold, which does not produce yield to holders but does affect the issuer's solvency.

The Act's gray area is coupon-style rewards and fee discounts. An issuer can run a loyalty program that gives holders airdrops of its own governance token, fee discounts on its own exchange, or rebates on transaction volume. None of these are literally "yield on the stablecoin balance." Whether regulators treat them as disguised yield depends on how economically material they are and how closely they track the issuer's reserve income. Expect early enforcement actions to define this line case by case.

The harder edge is the offshore loophole. A non-US issuer, or a US issuer routing rewards through an affiliated foreign entity, can in principle offer a return on stablecoin balances that look identical to yield. The Act addresses this through its foreign-issuer provisions, which we cover below, but enforcement against a rewards program run from Singapore or the Cayman Islands is harder than enforcement against a federally chartered US issuer.

State vs OCC vs FDIC: which license an issuer picks

The Act creates three regulatory paths for a payment stablecoin issuer, and the choice has practical consequences for users and builders.

State money-transmission license. A state-licensed issuer, meaning one already regulated under a state regime that the Treasury Secretary determines is "substantially similar" to the federal standard, can continue operating without a separate federal charter. Circle fits here. New York Department of Financial Services supervision of Paxos-issued tokens like PYUSD also fits here, as does Wyoming's SPDI regime. Holders see the same state-based consumer protections they had before, now plus the federal floor.

OCC national trust bank charter. The Act authorizes the Office of the Comptroller of the Currency to charter a new category of limited-purpose trust bank for payment stablecoins. This is the path most likely to attract new entrants because it offers a single federal license covering all 50 states, federal preemption of weaker state rules, and direct access to Federal Reserve payment rails. Several firms, including Circle-affiliated entities and at least one Tether-linked applicant, have publicly explored or applied for similar structures under prior frameworks.

FDIC-insured depositary institution. A bank that is already FDIC-insured can issue payment stablecoins through a subsidiary, with the bank's own regulator supervising reserves and the OCC supervising the stablecoin-specific activities. This is the most conservative path and the one most likely to be used by incumbents who already have a banking license. The trade-off is full bank-style regulation, including capital and liquidity requirements under the Basel framework as applied in the US.

For users, the visible difference is mainly in recovery: a federally chartered issuer enters a single federal resolution regime, while a state-licensed issuer enters the resolution regime of its home state. For builders, the choice shapes which API set, which compliance review, and which on-ramp partners an issuer will accept.

Federal preemption vs state regimes

Before the Act, a stablecoin issuer needed money-transmission licenses in dozens of states, each with its own capital, audit, and consumer-protection rules. That gave states real power, including the power to push issuers out (New York's BitLicense saga is the famous example) or to set a high bar (Wyoming's SPDI and New York's DFS regime are widely considered the most demanding).

The Act preempts state regimes only where they are weaker than the federal floor. A state can keep stricter rules, including higher capital requirements, more frequent audits, or tighter redemption windows. It cannot, however, allow an issuer to do something the federal law forbids, such as paying yield or holding non-eligible reserves.

For holders in a strict state like New York, this is mostly neutral. They were already getting strong consumer protection; the federal floor layers on top of it. For holders in a permissive state, the federal floor raises the bar. The practical effect is convergence toward the highest common denominator, which is closer to where Circle, Paxos, and a handful of others already operate.

One real tension: state regulators retain authority over money transmission for non-covered stablecoins, meaning algorithmic tokens, tokenized money market funds, and foreign-pegged stablecoins that do not meet the Act's definition. Expect that boundary to be litigated.

Foreign issuers and the reciprocity test

The Act does not stop at the border. A foreign issuer that wants to serve US persons must meet three conditions, enforced through Treasury and the OCC: its home regulator must have rules substantially similar to the US regime, including reserve composition, redemption rights, audit, and AML; the issuer itself must comply with US sanctions and anti-money-laundering rules at the level of a US issuer; and Treasury must publish a list of qualifying jurisdictions, updated at least annually.

The practical effect on USDT is the central question. Tether is incorporated outside the US, holds most reserves outside the US, and has historically resisted US oversight. Under the Act, if Tether wants to keep serving US customers, it has a choice: qualify under the reciprocity regime, set up a US subsidiary that obtains a federal or qualifying state license, or exit the US market. Each path is operationally heavy, and the cost-benefit depends on how much of Tether's volume is genuinely US-driven versus routed through offshore exchanges.

For users, the visible change is a slow narrowing of which stablecoins are accessible from US-based front-ends, exchanges, and custodians. Over 2025 and 2026, expect major venues to delist non-compliant foreign stablecoins for US persons, much as they delisted privacy coins a few years ago.

How this interacts with the SEC and CFTC

The Act does not classify payment stablecoins as securities, and that is a deliberate choice. It also does not classify them as commodities in the CFTC sense, although the CFTC retains jurisdiction over stablecoin fraud and manipulation under existing authority. The result is a stablecoin that is, in regulatory terms, its own thing.

That leaves several interfaces live. The SEC still oversees anything sold as part of an investment contract involving a stablecoin, for example a yield-bearing product or a tokenized fund wrapped in a stablecoin. The CFTC oversees derivatives, perpetuals, and fraud in spot markets. State regulators continue to oversee consumer protection. FinCEN continues to oversee anti-money-laundering compliance.

The unresolved debate is whether interest-bearing or yield-bearing stablecoins, structured as tokenized money market funds, should fall under the Act or under securities law. The Act explicitly excludes them, which keeps products like BUIDL and similar tokenized Treasury funds in the SEC's territory. Builders designing stablecoin-based savings products should plan for that boundary and not assume a payment-stablecoin license covers a yield product.

What this means for a US holder or builder

For a US holder using USDC, USDT, USD1, PYUSD, or RLUSD, the practical checklist for the next year is short.

• Identify whether each token you hold is issued by a US-regulated entity under a state regime deemed substantially similar, by a federally chartered issuer, or by a foreign issuer whose jurisdiction qualifies. Your exchange or wallet provider should disclose this, and if it does not, ask.
• Do not treat any stablecoin balance as FDIC-insured. Reserve quality is high, audit cadence is improving, but you remain a general unsecured creditor of the issuer in an insolvency. Diversifying across two or three issuers from different jurisdictions reduces single-issuer concentration risk without eliminating it.
• Watch for delistings. If you trade on a US venue, expect non-compliant foreign stablecoins to disappear from US order books over time. If you self-custody, the token still trades on-chain, but US-dollar ramps may close.
• Be skeptical of stablecoin "yield" products. The Act forbids yield passthrough from the issuer itself, but DeFi protocols and offshore affiliates still offer returns on stablecoin balances. Read the structure: is the return from protocol fees, from a third-party lending market, or from the issuer's reserves? Each has a different risk profile and a different regulatory treatment.

For a US builder, the Act opens three doors. You can apply for an OCC trust bank charter and access Federal Reserve payment rails in a single license, you can partner with an existing state-licensed issuer as a distribution or wallet layer without taking on issuer risk, or you can build on top of compliant tokens and accept that you are operating at the intersection of payments, banking, and securities rules. None of these is simple, but all are more defined than they were before.

Follow GENIUS Act fallout the smart way

Stablecoin regulation moves in small, technical steps that compound into big market shifts. Treasury reciprocity lists, OCC charter approvals, state-by-state enforcement actions, and delistings at major exchanges all change which tokens are usable, where, and at what cost. Tracking those signals by hand is a losing game. Zippfeed surfaces stablecoin and payments headlines with sentiment scoring (bullish, neutral, or bearish) and an importance rating, so you can see which moves are noise and which actually shift the rules you operate under.
