GENIUS Act vs MiCA is the comparison every dollar stablecoin issuer with European customers now has to make, and the two regimes are less alike than the word “stablecoin” suggests. The United States framework is one statute, Public Law 119-27, that regulates one product, the payment stablecoin, through a Federal-or-State licensing choice and takes effect on 18 January 2027. The European framework is Regulation (EU) 2023/1114, which regulates two token types and an entire service industry, and has applied to stablecoin issuers since 30 June 2024.
This GENIUS Act vs MiCA guide compares the two on the questions an issuer actually decides on: who may issue, what backs the token, what the holder is promised, what the issuer may not do, and who supervises. It reads the GENIUS Act from the enrolled text on govinfo and MiCA from the Regulation on EUR-Lex.
The GENIUS Act regulates a single thing, the payment stablecoin: a digital asset designed for payment or settlement, redeemable by its issuer for a fixed amount of monetary value, and held out as stable against that amount. It does not regulate exchanges as such, beyond the offer-and-sale limits in section 3(b) and the foreign-issuer provisions in section 8. It does not regulate other crypto-assets at all.
MiCA regulates two kinds of stablecoin and everything around them. An e-money token references a single official currency and is the nearest thing to a payment stablecoin; an asset-referenced token references anything else, including a basket. It then regulates crypto-asset service providers, white papers for other crypto-assets, and market abuse. A firm that only issues a dollar token touches one title of MiCA; a firm that also runs a platform touches most of it. The CASP authorisation is a separate exercise from the token.
| Question | GENIUS Act | MiCA |
|---|---|---|
| Who may issue | A permitted payment stablecoin issuer: a bank subsidiary, a Federal qualified issuer approved by the Comptroller, or a State qualified issuer (section 2(23)) | An e-money token may be issued only by a credit institution or an authorised electronic money institution; an asset-referenced token by an authorised issuer or a credit institution |
| Route for a nonbank | Federal approval by the OCC under section 5, or State approval under a certified regime below $10 billion | Authorisation as an electronic money institution in a Member State, then passporting |
| Decision clock | 120 days from a substantially complete application; silence is deemed approval (section 5(d)) | Set by the authorising regime; no deemed approval |
| Foreign issuers | Section 18 exception: comparable-regime determination by Treasury, registration with the Comptroller, US-held reserves | No equivalence route for issuers; issue through an EU-authorised entity |
The structural GENIUS Act vs MiCA difference is the bank. In the United States a nonbank can become an issuer in its own right and be supervised exclusively by the OCC under section 4(b). In the European Union an e-money token issuer is, by definition, a bank or an e-money institution, so the licensing question and the token question are the same question.
The GENIUS Act’s reserve rule is a closed list. Section 4(a)(1)(A) requires reserves of at least 1 to 1 in eight enumerated classes: cash and Federal Reserve balances, demand deposits at insured institutions, Treasuries of 93 days or less, overnight repo and reverse repo, government money market funds, regulator-approved Federal Government assets, and tokenised forms of most of those. Section 4(a)(2) forbids reuse with three exceptions. The reserve requirements are the subject of their own guide.
MiCA’s rule for an e-money token is built on the e-money safeguarding tradition. Funds received in exchange for the token are safeguarded, with at least 30 percent held on deposit in separate accounts at credit institutions and the remainder invested in secure, low-risk assets denominated in the same currency as the token. An asset-referenced token has a reserve of assets with its own composition, custody and investment rules. Both regimes reach the same destination, high-quality liquid assets held apart from the issuer’s own money, by different roads, and a treasury policy written for one will not pass the other unedited.
Here the GENIUS Act vs MiCA comparison finds more agreement than anywhere else. Under the GENIUS Act, section 4(a)(1)(B) requires a public redemption policy with clear and conspicuous procedures for timely redemption, all fees disclosed in plain language and changeable only on 7 days’ notice, and no discretionary limit on timely redemption except one a regulator imposes. Under MiCA, an e-money token holder has a claim against the issuer and a right to redeem at par, at any time, at face value.
Both forbid interest. Section 4(a)(11) prohibits any interest or yield to a holder solely in connection with holding, using or retaining the stablecoin, in cash, tokens or other consideration, and it binds foreign issuers too. MiCA prohibits the granting of interest on both e-money tokens and asset-referenced tokens. An issuer looking at GENIUS Act vs MiCA for a loophole on yield will find neither regime offers one.
On size, GENIUS Act vs MiCA is a contrast in purpose. The GENIUS Act uses size to allocate supervision. A State qualified issuer may stay under a certified State regime only up to $10 billion in consolidated total outstanding issuance; above it, section 4(d) requires transition to Federal oversight within 360 days or a halt to new issuance. Above $50 billion, section 4(a)(10) requires annual GAAP financial statements audited to PCAOB standards. There is no cap on how large a permitted issuer may grow.
MiCA uses size to escalate supervision and, for non-euro tokens, to cap use. A token becomes significant on criteria that include more than 10 million holders or a reserve above 5 billion euro, at which point supervision moves to the European Banking Authority and stricter requirements apply. And an asset-referenced token, or an e-money token denominated in a currency that is not an official currency of a Member State, whose use as a means of exchange within a single currency area exceeds both 1 million transactions and 200 million euro per day must stop issuing. For a dollar stablecoin sold in Europe, that usage cap is the provision with no American counterpart.
The two supervisory models differ in origin. The GENIUS Act’s is the bank model. Section 6 gives the primary Federal regulator examination, cease-and-desist, removal and civil money penalty powers borrowed from the Federal Deposit Insurance Act, with penalties of up to $100,000 per day. Section 4(a)(5) makes the issuer a Bank Secrecy Act financial institution with six enumerated AML and sanctions elements. And section 4(a)(6)(B) makes the technological capability to comply with any lawful order to seize, freeze, burn or prevent transfer a condition of issuing at all.
MiCA supervises through national competent authorities, with the EBA for significant tokens, and applies the EU anti-money laundering framework through the issuer’s status as a credit or e-money institution. It has no equivalent of the section 4(a)(6)(B) condition: nothing in MiCA makes a contract-level burn capability a precondition of issuance. An issuer building one token contract for both markets builds it to the American specification, because that is the stricter one on this point. The wider section 4 requirements set out the rest.
The realistic GENIUS Act vs MiCA case is a dollar stablecoin issued by a United States permitted issuer and offered in the European Union through an EU-authorised e-money institution issuing an e-money token. The two entities share a brand and a treasury discipline, and not much else on paper: separate authorisations, separate reserves held to separate rules, separate white paper and redemption disclosures, and, for the EU token, the usage cap to monitor. The one thing that can be built once is the token contract, to the GENIUS Act’s lawful-order standard, which MiCA does not object to and the OCC will require.
Only through section 18. If Treasury determines that the EU regime is comparable to the Act’s requirements, including section 4(a), an EU issuer may register with the Comptroller, hold reserves in a United States financial institution sufficient for US customers, and offer in the United States without becoming a permitted issuer. No such determination existed when this was written.
Neither is looser; they are differently shaped. The GENIUS Act’s list is closed and short-dated, with a 93-day Treasury ceiling. MiCA’s e-money safeguarding sets a 30 percent deposit floor and a same-currency low-risk-asset requirement. A reserve that satisfies both is possible but has to be designed to both.
Yes. Section 4(a)(11) of the GENIUS Act and the MiCA prohibitions on interest for e-money tokens and asset-referenced tokens reach the same result: holders may not be paid for holding.
No. MiCA’s stablecoin titles have applied since 30 June 2024 and its grandfathering for service providers ended on 1 July 2026. The GENIUS Act takes effect on 18 January 2027, with the service-provider offer-and-sale prohibition following on 18 July 2028.
An issuer on both sides of GENIUS Act vs MiCA needs two document sets that do not contradict each other. Our GENIUS Act Toolkit carries the American side, 126 templates built on Public Law 119-27, and the MiCA Toolkit carries the European one. The reserve policy, the redemption policy and the lawful-order standard in the GENIUS Act Toolkit are the three to read first, because they are the three that MiCA does differently.
