GENIUS Act and US Stablecoin Regulation: A 2026 Guide for Merchants

If you accept stablecoins as payment for your business, the GENIUS Act almost certainly doesn't require you to hold a license. The law regulates the companies that issue stablecoins – Circle, PayPal, Tether – not the merchant taking USDC for a subscription or an online order. That single line separates the businesses this law targets from the ones simply reading about it in a panic.

This guide clarifies the difference. It covers what the GENIUS Act actually does, who has to comply, when the rules come into effect, which stablecoins are safe to accept from US customers, and the one deadline, July 2028, that even non-issuers should be aware of. Primary sources are linked where the detail matters.

What is the GENIUS Act?

The GENIUS Act (Guiding and Establishing National Innovation for U.S. Stablecoins) is the first US federal law governing payment stablecoins. President Trump signed it on 18 July 2025 as S.1582 in the 119th Congress.

Previously, stablecoin issuers had to navigate a patchwork of state money transmitter rules. The GENIUS Act replaces this patchwork with a single federal standard, setting out who can issue a dollar-pegged stablecoin, how issuers must hold reserves, and what they can and cannot offer customers. According to the US Treasury, the Act is designed to encourage innovation while protecting consumers and addressing risks relating to illicit finance and financial stability.

For a business that accepts these tokens, the value is indirect but real. A stablecoin issued under the GENIUS Act is a dollar backed by rules, not just by a company's promise.

How the law defines a "payment stablecoin"

The GENIUS Act only governs payment stablecoins, and the definition is deliberately narrow. A payment stablecoin is a digital asset designed to be used as a means of payment or settlement, pegged to a fixed monetary value, where the issuer is obligated to redeem it at par.

The keyword is payment. Anything that returns yield to the holder – tokenized money-market funds, staking-style products, lending positions – sits in a different legal box entirely. That distinction runs through the whole law, and it's why USDC and PYUSD are marketed as settlement tools while yield-bearing tokens are structured separately.

Merchant or issuer? Where the GENIUS Act stops applying to you

This question decides whether the law is your concern or your provider's, and it's the one most coverage skips.

The GENIUS Act imposes its obligations on permitted payment stablecoin issuers (PPSIs), the companies that create and redeem stablecoins. Reserve rules, audits, certifications, licensing: it all lands on the issuer.

Accepting a stablecoin as payment makes you neither an issuer nor a PPSI. When a customer pays you 200 USDC for your product, and you keep or convert it as revenue, you're a merchant receiving payment. The law's issuer obligations don't touch you.

Where a business could cross into scope

The line moves if you start doing issuer-like or distribution-like things. Worth knowing the edges:

• You issue your own stablecoin (a branded token, a loyalty coin pegged to the dollar). That's issuance, and you'd need to be a PPSI.
• You distribute stablecoins to US users as a service, which brings the digital-asset-service-provider rules into play (more on the 2028 deadline for that below).

If neither describes you, you're a merchant, and the compliance weight sits upstream with the issuer and your payment provider. If either does, get legal advice, because the thresholds and penalties here are serious.

The practical rule: accepting a stablecoin as payment isn't regulated issuance. Creating or distributing one can be.

The 1:1 reserve requirement

This is the core promise the law enforces, and it's what makes a GENIUS-compliant stablecoin trustworthy for settlement.

Every permitted issuer must back its stablecoin at a 1:1 ratio with high-quality liquid reserves. Issuers cannot fractionally back or lend the reserves. The permitted assets are tightly defined:

• US dollars and cash
• Short-dated US Treasury bills (93 days or less to maturity)
• Repurchase agreements backed by Treasuries
• Government money-market funds holding those assets

Rehypothecation is prohibited – the issuer can't reuse reserve assets as collateral elsewhere. For a business, this is the reassurance that matters: a payment stablecoin under the GENIUS Act is genuinely redeemable at par because the dollar behind it is actually sitting there, in cash or near-cash, not deployed into something riskier.

Who can issue a stablecoin: the three paths

The GENIUS Act creates three routes to becoming a permitted issuer, and all of them require the entity to be formed in the United States.

1. Subsidiary of an insured bank

A subsidiary of an insured depository institution can issue under the supervision of that bank's existing federal regulator.

2. Federal qualified issuer (OCC)

A non-bank entity can seek approval from the Office of the Comptroller of the Currency (OCC), the primary federal regulator, which published its 376-page notice of proposed rulemaking on 25 February 2026. 

3. State qualified issuer

An issuer with $10 billion or less in outstanding stablecoins can operate under an approved state regime, provided it is certified as substantially similar to the federal regime. Once the $10 billion threshold is crossed, the issuer must transition to federal oversight.

This tiered system lets smaller, state-level innovation flourish while ensuring the largest issuers remain under federal supervision. For merchants, the takeaway is simple: compliant stablecoins come from entities that have cleared one of these three gates.

When does the GENIUS Act take effect?

The law is signed, but not yet fully operative, and the timing has a wrinkle worth understanding.

The GENIUS Act takes effect on the earlier of two dates: 18 months after enactment (18 January 2027), or 120 days after the primary federal regulators issue their final rules. Whichever comes first.

As of mid-2026, the relevant agencies had not finalized their rules, and the Federal Reserve in particular had not published its proposal. Because the 120-day clock starts only once regulators finish, and that had not yet happened, the effective date is widely expected to be the statutory backstop of 18 January 2027, as stated in the Treasury's own rulemaking notice.

For a US-facing business, that's your practical horizon. From that date, issuing a payment stablecoin in the US without a license is prohibited.

The yield ban, and why it matters to a merchant

Here's the most-discussed provision, and its consequences reach further than the issuers it targets.

The GENIUS Act prohibits issuers from paying yield or interest to stablecoin holders. A payment stablecoin is a settlement instrument, not a savings product. If a token pays you to hold it, it's legally something else, with its own separate disclosures.

What this changes for your treasury

The non-issuer may find it tricky to see the practical effect. Your payment provider or wallet cannot legally offer you 'interest on your stablecoin balance' as part of a payment product. If a provider offers yield on held balances, this is a red flag, because compliant payment stablecoins don't work that way.

It reshapes treasury logic, too. Yield is not earned by idle stablecoin balances just by sitting there, so an opportunity cost rather than a return is faced by those holding large balances for the sake of it. A better approach is to settle, convert, or deploy funds deliberately rather than treating a stablecoin float as an interest-bearing account. It isn't one by law.

Foreign issuers, USDT, and the reciprocity question

This is where the most-asked coin meets the most-technical part of the law, and it matters for anyone with US-facing customers.

The GENIUS Act sets a separate track for foreign issuers. A stablecoin issued outside the US can be offered to US persons only if the Treasury makes a reciprocity determination, a finding that the issuer's home jurisdiction has a comparable regulatory regime, and the issuer meets registration and reserve conditions.

Where USDT stands

Tether, USDT's issuer, is domiciled in El Salvador and hadn't obtained a reciprocity determination as of mid-2026. That leaves USDT in an unresolved position for US distribution under the new framework. Tether responded by launching a separate US-focused token, USAT, in January 2026 through the Anchorage Digital bank charter, structured to comply directly with the GENIUS Act.

So there are effectively two Tether products now: the global USDT, which carries roughly a quarter of its reserves in assets the Act doesn't permit for a compliant payment stablecoin (gold, Bitcoin, secured loans), and the US-native USAT, built for the American market. The deadline for foreign issuers to fall in line runs to 18 July 2028, the same safe-harbor horizon covered below.

USDT isn't banned in the US. It's a non-permitted stablecoin under a law that's still phasing in, which is a different and more manageable problem than a ban.

Which stablecoins should you accept from US customers?

Here's the abstract law turned into a checkout decision, which is what you actually came for.

For a US-facing business, USDC and PYUSD are the clean defaults, both issued by US-regulated entities on a compliant path. USAT is Tether's compliant US answer. USDT still works today, and your customers still hold it in volume, but the direction of travel is clear, and the sensible setup is to accept what a customer wants to pay with while settling into a compliant stablecoin.

That last point is the practical bridge. A processor with auto-conversion lets a customer pay in the coin they hold and converts it to USDC or another compliant asset on arrival, so your settled balance sits in a permitted stablecoin regardless of what came in.

The cash-equivalent trap: how non-permitted stablecoins hit your books

This is a detail that almost no crypto guide mentions, and it gives you a genuine advantage.

Section 3(g) of the GENIUS Act contains a specific provision stating that a stablecoin that is not a permitted payment stablecoin cannot be treated as a cash equivalent for the accounting purposes of certain regulated entities. Once these rules come into effect, holding a non-permitted stablecoin is not the same as holding cash on the balance sheet.

For most ordinary merchants, this is a background consideration rather than an immediate one. However, if your business is involved in regulated financial reporting or you hold significant stablecoin balances, the classification is important: a non-permitted stablecoin may be recorded on your books as something other than cash, with accounting and treasury implications. This is another reason why settling into a permitted stablecoin is preferable, and a question you should ask your accountant before the end of the year rather than after.

AML, sanctions, and the Bank Secrecy Act

Although compliance obligations under the GENIUS Act fall on issuers, these obligations shape the entire ecosystem in which you operate.

Permitted issuers are treated as financial institutions under the Bank Secrecy Act. This means they must implement full AML programs, ensure sanctions compliance, report suspicious activity, and be able to freeze or block tokens tied to sanctioned addresses. This has practical implications similar to those already seen with USDT and USDC: a compliant stablecoin issuer can and will freeze tokens at a flagged address.

For you, the takeaway is the same as on any chain. Use a payment provider that screens incoming transactions in real time so that payments traceable to a sanctioned source do not settle onto your balance and become your problem. The issuer's BSA obligations and your provider's screening work together to protect the merchant, who never sees the compliance machinery running underneath.

What happens if an issuer goes bankrupt?

This is a genuine consumer-protection win in the law, and it's worth knowing because it changes the risk profile of holding a compliant stablecoin.

Under the GENIUS Act, stablecoin reserves are ring-fenced from the issuer's bankruptcy estate, and holders get priority over all other creditors in claiming them. If a permitted issuer fails, the reserves backing your stablecoin aren't pooled into the general creditor scramble; they're earmarked for redemption to holders first.

In plain terms: a compliant payment stablecoin is legally structured so that the dollars behind it come back to you before they go to anyone else the issuer owed. That's a stronger position than an unsecured deposit, and it's one concrete reason the "regulated" in "regulated stablecoin" has value beyond a marketing label.

GENIUS Act vs MiCA: two frameworks, one direction

If you operate across the US and EU, the two big frameworks rhyme more than they clash. A quick comparison:

The convergence is the story. Both ring-fence reserves, both ban yield on payment stablecoins, and both leave ordinary merchants outside the licensing net. For a business, that means a stablecoin strategy built for one framework travels reasonably well to the other. Our MiCA guide for merchants covers the EU side in the same practical detail.

The GENIUS Act doesn't regulate all crypto.

This misconception leads people to the wrong conclusions, so it's worth stating plainly.

The GENIUS Act governs payment stablecoins, and only payment stablecoins. It says nothing about whether Bitcoin is a commodity or a security, how exchanges are regulated, or DeFi or NFTs. Those questions sit with a separate piece of legislation, the CLARITY Act, which addresses digital-asset market structure and moved through Congress on its own track.

So "the US regulated crypto in 2025" is only half true. It regulated stablecoin issuers. This law didn't touch Bitcoin, Ether, or the rest of the market. Keeping the two straight saves you from reading stablecoin rules as if they governed your entire crypto operation, because they don't.

What non-US businesses with US customers need to know

Top search results tend to ignore this scenario, which is the main one for many readers.

If you're based in LATAM, Southeast Asia, or the EU, but sell to US customers, the GENIUS Act affects your payment options even though it doesn't apply to you. As you are not an issuer, you do not require authorization. However, the stablecoins available to your US customers through compliant channels are subject to US law, which encourages you to settle in USDC, PYUSD or another permitted token when serving that market.

The same practical approach that works domestically applies here: accept the coin your customer holds, convert it on arrival and settle in a compliant stablecoin. This approach ensures your US-facing revenue remains in assets that meet the new standards, without forcing customers to use a particular coin at checkout. This is the least disruptive way to stay aligned with a framework that you are not directly subject to, but cannot ignore.

The July 2028 deadline even non-issuers should watch

Here's the date buried in legal analyses and worth putting in plain sight, especially for payment platforms and service providers.

The GENIUS Act gives digital asset service providers a safe harbor until 18 July 2028. From that date, a DASP, an exchange, wallet, or platform distributing stablecoins to US persons, may only offer permitted payment stablecoins. Non-permitted stablecoins can't be sold or distributed to US users past that line (Federal Register).

What this means in practice

You have a runway. Three years is a long time in the cryptocurrency world, and there is no reason to expect an overnight change. However, the direction is fixed, so the sensible response is not to wait until 2028. Ask your provider which stablecoins it will support for US customers after the safe harbor ends, and ensure your settlement can move to compliant tokens without changing your checkout process. Businesses that ask early will treat 2028 as a planned migration. Those that don't will treat it as a fire drill.

How to prepare: a merchant's checklist

This turns the whole law into a short list of actions, which is the highest-value takeaway.

• Confirm you're a merchant, not an issuer. If you accept crypto as payment for your own goods and don't hold, exchange, or distribute stablecoins for others, you're outside the licensing net.
• Default to compliant stablecoins for US settlement. USDC and PYUSD are the clean choices; USAT is Tether's compliant US token.
• Set up auto-conversion. Accept what the customer holds, settle in a permitted stablecoin, so your balance stays clean regardless of what comes in.
• Ask your provider about the July 2028 horizon. Which stablecoins will it support for US customers after the safe harbor ends?
• Question any "yield on balance" offer. Compliant payment stablecoins can't pay holders interest; a provider promising it is worth scrutinizing.
• Check the cash-equivalent treatment of any non-permitted stablecoin you hold, especially if you touch regulated financial reporting.
• Keep GENIUS and CLARITY separate. This law is about stablecoins, not your whole crypto operation.

Which stablecoin is best for a US business to accept in 2026 comes down to this: a compliant token from a US-regulated issuer, settled through a provider that screens incoming payments and can move with the rules.

To sum up

The GENIUS Act achieved something more specific and useful than the headlines suggested. Rather than regulating all of crypto, it established federal rules for payment stablecoins, including full reserves, no yield, ring-fenced funds in the event of bankruptcy, and a clear distinction between issuers, who must comply, and merchants, who simply accept the tokens.

For businesses, almost none of the heavy machinery is theirs to operate. You don't need a license to accept stablecoins. What you do need is a sensible settlement default – USDC, PYUSD or another compliant token – and a provider that converts on arrival and screens what comes in. Get that right, and the law will work in your favor, providing you with dollars that are backed by rules rather than by a single company's promise.

The one date to note is 18 July 2028. Not because it forces action tomorrow, but because businesses that plan their stablecoin mix around it now will glide through, while those that ignore it will struggle. In a topic this loaded with legal detail, that's the piece of planning worth doing early.
