MiCA vs the GENIUS Act: how the two big stablecoin regimes compare

MiCA and the GENIUS Act are the two regimes that now define how regulated stablecoins work in the world’s two largest financial markets, and they take visibly different routes to the same goal: a token that is always worth what it claims. MiCA, in force for stablecoins since 30 June 2024, folds stablecoin issuance into the EU’s existing financial licensing system. The GENIUS Act, signed 18 July 2025 and taking effect on the earlier of 18 January 2027 or 120 days after final rules, builds a new, purpose-made federal category for one product only: the payment stablecoin.

For any institution that moves money across both jurisdictions, the practical question is not which regime is better. It is that the two produce different lists of usable tokens, different issuer obligations, and different timelines, and a payment that is compliant in one corridor may not be in another.

The comparison at a glance

Dimension	MiCA (EU)	GENIUS Act (US)
What it covers	The whole crypto-asset market; stablecoins as e-money tokens (EMTs) and asset-referenced tokens (ARTs)	Payment stablecoins only
Who may issue	Credit institutions and e-money institutions (EMTs); authorized issuers (ARTs)	Permitted payment stablecoin issuers: bank subsidiaries, federal-qualified nonbank issuers, or state-qualified issuers
Reserves	Full backing; strict asset and custody rules; part held as bank deposits	1:1 in cash and high-quality liquid assets such as short-dated Treasuries
Redemption	At par, on demand, free of charge for EMTs	At par under a published redemption policy
Yield to holders	EMT issuers may not pay interest	Issuers may not pay interest or yield to holders
Supervision	National authorities; EBA for significant tokens	Primary federal regulator by issuer type; state supervisors for state-qualified issuers
Status (July 2026)	Fully applying; 21 authorized EMT issuers across 12 countries	Proposed rules out from OCC, Treasury, FDIC, NCUA, FinCEN; finals due from 18 July 2026

Scope: a market regime versus a product regime

MiCA regulates an entire market. Stablecoins occupy two of its categories: e-money tokens, which reference a single official currency, and asset-referenced tokens, which reference baskets or other assets. Nearly all institutional flow runs through EMTs, and an EMT issuer must be a credit institution or an e-money institution, which is why the authorized list is populated by entities such as Circle’s French e-money arm and Société Générale’s FORGE.

The GENIUS Act regulates a product. It defines the payment stablecoin, creates the permitted payment stablecoin issuer, and leaves the rest of the digital-asset market to other laws. An issuer can be a subsidiary of an insured depository institution, a federal-qualified nonbank issuer approved by the OCC, or a state-qualified issuer under a state regime that Treasury deems substantially similar to the federal one, an option that stays available while the issuer remains under $10 billion outstanding.

Reserves and redemption

Both regimes require full backing and redemption at par; the differences are in composition and mechanics. The GENIUS Act enumerates eligible reserve assets, cash, demand deposits, short-dated Treasury bills and similar high-quality liquid assets, and requires monthly public disclosure of reserve composition with executive certification. MiCA sets asset-quality, segregation, and custody rules and requires EMT redemption on demand, at par, without fees.

Neither lets the holder earn from the float: MiCA bars interest on EMTs, and the GENIUS Act bars issuers from paying yield to holders. In both markets, the economics of issuance sit with the issuer, which is one reason banks are examining tokenized deposits, where the deposit relationship, and its economics, stay on the bank’s balance sheet.

Supervision and the federal-state seam

MiCA supervision runs through national competent authorities, with the European Banking Authority stepping in for tokens classed as significant. The GENIUS Act splits supervision by issuer type: bank subsidiaries answer to their bank’s federal regulator, nonbank federal issuers to the OCC, and state-qualified issuers to their state supervisor under the substantially-similar standard Treasury proposed in April 2026. The seam between those paths, and when a growing issuer must cross it, is one of the questions the 2026 rulemakings are settling; through the spring of 2026 the OCC, FDIC, NCUA, Treasury, and FinCEN all published proposed rules, including customer identification and sanctions-compliance standards proposed in June 2026.

Extraterritorial reach

MiCA applies to tokens offered in the EU regardless of where the issuer sits, which is why USDT’s lack of authorization led major exchanges to delist it for EEA users. The GENIUS Act reaches foreign issuers through a comparability route: Treasury determines whether a foreign regime is comparable, foreign issuers register with the OCC, and reciprocal-arrangement regulations are due by July 2027. Until recognition arrangements exist, compliance is jurisdiction by jurisdiction.

What this means for institutions operating across both

The two regimes are converging on substance, full reserves, par redemption, no holder yield, real supervision, and diverging on lists. Which token, from which issuer, is usable in which corridor is now a compliance fact that changes as authorizations land: an EU corridor wants a MiCA-authorized EMT, a US corridor will want a GENIUS-permitted token once the regime takes effect, and treasury teams need policies, not one-off decisions, to keep pace. The full country-by-country picture, including the UK, Hong Kong, Singapore, the UAE, and Japan, is in our stablecoin regulation map.

Where Frame fits

Frame is the settlement layer for global finance: one integration to orchestrate payments at scale across fiat rails, stablecoins, and tokenized deposits, with compliance enforced on every transaction and settlement in seconds instead of days.

Divergent stablecoin regimes are precisely the problem a rail-neutral settlement layer absorbs. Frame is neutral across rail types and coin-neutral within the stablecoin rail, so jurisdictional rules become routing policy rather than architecture: a policy can require MiCA-authorized tokens on EU corridors and permitted issuers’ tokens on US corridors, and Frame’s Rules Engine evaluates every transaction against those policies inside settlement itself. A transfer that cannot satisfy the policy that governs it does not settle, and every settled transaction produces verifiable evidence that its conditions were met. For banks, payment providers, exchanges, platforms, and enterprises, that turns two rulebooks, and the next one, into configuration instead of re-engineering.
