GENIUS Act Final Rules: What Happens on July 18 and What Merchants Need to Know

On July 18, 2026, a legal deadline becomes real for every stablecoin in the US market. Six federal agencies must finalize their rules under the GENIUS Act on or before that date. Those rules determine who can legally issue a payment stablecoin in the United States, how much capital they must hold, and what happens when someone wants to redeem their stablecoin for dollars. Most coverage of this deadline treats it as a story about banks and issuers. For merchants who accept stablecoins in daily operations, the consequences are different and worth understanding directly.

Why July 18 Is Different From Every Other Regulatory Deadline

The GENIUS Act was signed into law on July 18, 2025. It created a legal category called "permitted payment stablecoin issuers" and gave six federal agencies exactly one year to write the rules that define what that category actually means in practice. That deadline is July 18, 2026.

What makes this deadline unusual is that all six agencies are writing their rules in parallel, not in sequence. The OCC finishes at the same time as the FDIC, FinCEN, OFAC, NCUA, and Treasury. The entire regulatory picture for US-issued stablecoins shifts in one coordinated event rather than piece by piece. For the past year, stablecoin issuers have operated under the law itself but without the specific implementing rules. July 18 closes that gap.

For context on how the GENIUS Act reshaped the stablecoin legal landscape at a higher level, the GENIUS Act merchant guide covers the original law in detail. This piece focuses on what the six agencies have actually proposed and what those specifics mean for merchants.

What the OCC Rules Actually Say

The Office of the Comptroller of the Currency governs national banks and federally chartered institutions. Under the GENIUS Act, it also becomes the primary regulator for federally issued payment stablecoins. Its proposed rules are the most specific of the six agencies and the most directly relevant to anyone thinking about the quality of the stablecoins they accept.

The OCC is proposing a $5 million minimum capital floor for new stablecoin issuers seeking federal approval. This is not the total amount of reserves backing the stablecoin supply. It is the minimum operational capital the issuer must maintain as a going concern, separate from the reserves. A stablecoin issuer that runs out of capital before it runs out of reserves still fails its customers, so the capital floor addresses a risk that reserve ratios alone do not cover.

Beyond the capital floor, the OCC is proposing a three-tier liquidity framework that requires issuers to hold 10% of outstanding supply in same-day liquid assets. This means that if 10% of USDC holders decided to redeem their tokens for dollars at once, Circle would need to cover that redemption within a single business day from assets that are already liquid. The remaining tiers cover medium-term and longer-term redemption capability.

For merchants, this matters in a concrete way. A stablecoin you accept in payment is only as reliable as the issuer's ability to redeem it for dollars when a counterparty needs dollars. The OCC's rules create a legally enforced minimum on that reliability for any issuer operating under federal charter.

What the FinCEN and OFAC Rules Mean for Payment Flows

FinCEN and OFAC jointly proposed rules that treat permitted payment stablecoin issuers as financial institutions under the Bank Secrecy Act. This is a significant classification. It means issuers must run formal anti-money laundering programs, file suspicious activity reports, and maintain sanctions-blocking capability that prevents stablecoin transfers to sanctioned individuals or entities.

These obligations fall on the issuer, not on merchants. A merchant accepting USDC does not need to file suspicious activity reports or run an AML program as a result of these rules. But the rules do change the compliance posture of the coins flowing through a merchant's account in a meaningful way.

Before these rules, a stablecoin issuer's commitment to block sanctioned transactions was a policy choice. After the rules take effect, it becomes a legal obligation enforceable by Treasury. For merchants operating in regulated industries or accepting payments from global customers, this matters because it shifts stablecoins from "we try to block bad transactions" to "we are legally required to block them with a formal program and face regulatory consequences if we do not."

The FDIC Position: What It Means to Hold Stablecoins as a Merchant

The FDIC's contribution to the July 18 framework is less about requirements on issuers and more about protections for holders. The FDIC position is that stablecoin tokens do not qualify for deposit insurance, regardless of whether the issuer holds their reserves in an FDIC-insured bank.

This distinction matters for merchants who hold meaningful stablecoin balances. FDIC deposit insurance covers up to $250,000 per depositor at an insured bank. If you hold dollars at a bank and the bank fails, FDIC covers your losses up to that limit. If you hold stablecoins and the issuer fails, FDIC does not cover your losses even if the issuer's dollars were sitting in an insured bank the day before the failure. The insurance covers the bank's deposit relationships, not the token holders downstream.

The practical implication is that the risk of holding stablecoins remains a counterparty risk on the issuer. The OCC's capital and liquidity requirements reduce that risk for federally chartered issuers, but they do not eliminate it and FDIC insurance does not backstop it. Merchants who need deposit insurance for their operating cash should keep those funds in a bank account rather than in stablecoin balances.

When Do These Rules Actually Take Effect

July 18 is the deadline for the agencies to finalize their rules, not the date the rules become effective. The GENIUS Act sets the effective date at the earlier of 120 days after finalization or January 18, 2027.

This means that if all six agencies finalize their rules on July 18, the rules become effective in mid-November 2026. If any agency finalizes later than September 19, 2026, the effective date defaults to January 18, 2027 regardless. Either way, stablecoin issuers have a runway of at least three to five months from finalization to comply.

For merchants, this runway matters because the stablecoins that pass through their payment systems will not change overnight on July 18. The coins will continue operating as they do now. What changes between July 18 and the effective date is that the issuer must prepare to meet the new requirements, and after the effective date, meeting those requirements becomes a legal condition of the issuer's license to operate.

How These Rules Affect Non-Custodial vs. Custodial Arrangements

One distinction the GENIUS Act draws that matters directly to merchants is between custodial and non-custodial arrangements. A custodial arrangement is one where a third party holds the private keys to a wallet on behalf of the merchant. A non-custodial arrangement is one where the merchant holds their own keys.

The compliance obligations under the GENIUS Act fall more heavily on entities that hold custody over customer funds. A custodial payment processor that holds a merchant's stablecoin balance between payment receipt and payout is in a different regulatory position than a non-custodial gateway where the merchant retains control of their own keys from the moment a payment settles.

This is the mechanism behind the non-custodial model's regulatory advantage under the new framework. For a detailed explanation of what non-custodial actually means technically and why the key-control question matters, see what a non-custodial crypto payment gateway does.

What Changes Before and After the GENIUS Act Rules

Area	Before final rules (now)	After effective date
Issuer capital requirements	Voluntary / market-driven	OCC-mandated $5M minimum floor for federal issuers
Redemption reliability	Policy commitment by issuer	Legally enforceable 10% same-day requirement
AML / sanctions compliance	Issuer discretion	Required by law, enforceable by Treasury
Deposit insurance for holders	Not covered by FDIC	Still not covered (FDIC position unchanged)
Legal status of stablecoins	GENIUS Act in force, no implementing rules	Full regulatory framework in effect
Non-US issuers (e.g. Tether)	Operating without US framework	Must register as foreign PPSI or face US market restrictions

What Merchants Should Do Before July 18

Most merchants accepting stablecoins do not need to take action before July 18. The rules apply to issuers, not to businesses that accept stablecoins in payment. But two things are worth confirming before the deadline.

First, check whether the stablecoins you accept are issued by an entity seeking federal charter under the GENIUS Act. Circle has been public about its GENIUS Act compliance plans and is expected to operate as a permitted payment stablecoin issuer. Tether's position is less clear because it operates primarily as an offshore issuer. The OCC's capital floor and liquidity requirements only protect holders of stablecoins issued by federally chartered PPSIs. If the stablecoin you rely on is not issued by a PPSI, those protections do not apply to you.

Second, check whether your payment gateway holds custody over your stablecoin balances between when a customer pays and when you withdraw. If it does, your gateway is in the chain of custodial relationships that the GENIUS Act's compliance obligations are designed to reach. If your gateway is non-custodial and you hold your own keys, you sit outside that chain.

AIO.cash is a non-custodial crypto payment gateway. Merchants who receive payments through AIO control their own wallet keys from the moment a payment settles. There is no AIO-held custodial balance and no AIO custody over merchant funds at any point. Pay-ins are 0.3% and payouts are 0%, with AIO covering the network gas so you never touch it directly.

Frequently Asked Questions

What happens on July 18, 2026 under the GENIUS Act?

Six federal agencies face a statutory deadline to finalize their implementing rules for the GENIUS Act on or before July 18, 2026. The agencies are the OCC, FDIC, NCUA, Treasury, FinCEN, and OFAC. Missing this deadline does not void the law, but each agency would need to justify the delay and continue rulemaking. Most agency comment periods closed June 9, 2026, putting final rules squarely in the June to July window.

Does the GENIUS Act affect merchants who accept stablecoins?

Not directly. The GENIUS Act's primary obligations fall on stablecoin issuers, not on businesses that accept stablecoins in payment. The indirect effect is that the stablecoins flowing through merchant payment systems will have higher compliance standards behind them once the rules take effect, including mandatory capital buffers and formal AML programs. Merchants who use a custodial payment processor may see their processor's compliance posture change as a result.

What is a permitted payment stablecoin issuer?

A permitted payment stablecoin issuer (PPSI) is the legal category the GENIUS Act created for entities that issue dollar-pegged stablecoins in the United States. To qualify, an issuer must obtain approval from the OCC, a state regulator, or a federal credit union regulator and comply with the capital, liquidity, and AML requirements each agency sets. Circle is expected to qualify as a PPSI. Tether's status depends on whether it seeks US registration as a foreign PPSI or continues operating primarily outside the US regulatory framework.

Will USDC and USDT still be available after GENIUS Act rules take effect?

USDC is expected to remain fully available. Circle has actively engaged in the GENIUS Act rulemaking process and has indicated plans to operate as a permitted payment stablecoin issuer. USDT's future US availability depends on whether Tether registers as a foreign PPSI with the OCC or continues operating without US authorization. Merchants with meaningful USDT exposure should monitor Tether's public statements on the GENIUS Act in the second half of 2026.

When do GENIUS Act rules actually go into effect?

If agencies finalize rules by July 18, 2026, the rules become effective 120 days later, which is mid-November 2026. If any agency finalizes after September 19, 2026, the effective date defaults to January 18, 2027. The rules impose obligations on issuers rather than on merchants, so the change for businesses is that the stablecoins they use will be operating under these requirements from that effective date, not from July 18 itself.
