MiCA Rules: Europe’s Live Crypto Rulebook
Regulation (EU) 2023/1114 — Markets in Crypto-Assets — is not a proposal. Stablecoin titles have applied since 30 June 2024. The CASP (crypto-asset service provider) regime has applied since 30 December 2024. The last grandfathering window closed 1 July 2026. As of mid-September 2026 the ESMA interim register lists on the order of 330–340 authorised CASPs. A Commission review consultation ran May–August 2026 on the gaps (staking, lending, global multi-issuance stablecoins, decentralization). That is a live statute plus a renovation debate, not a bill.
MiCA is what GENIUS + CLARITY are trying to become, with European choices already baked in.
How MiCA Slices the Market
| Bucket | What it is | Core rules |
|---|---|---|
| EMT (e-money token) | Single official currency (USDC, EURC) | Title IV. Issuer must be a credit institution or e-money institution. 1:1 funds, par redemption at any time, no interest to holders |
| ART (asset-referenced token) | Basket or non-single-fiat reference | Title III. Separate MiCA issuer authorisation, reserve of assets, segregation, redemption, no interest (Art. 40) |
| Other crypto-assets | BTC, ETH, utility tokens | Title II. White paper, offer rules; not a securities-law rewrite of Howey |
| CASP services | Custody, trading venue, exchange for funds, transfer, advice, portfolio mgmt, etc. | Title V. National licence, EU passport |
| Market abuse | Insider dealing, manipulation | Title VI (Arts. 86–92) |
The classification error that still shows up in U.S. notes: dollar and euro payment coins used by institutions are EMTs, not ARTs. ART reserve articles do not govern USDC. Title IV does.
Stablecoins: Stricter on Who May Issue, Clearer on Yield
Who may issue an EMT.
Only a bank or an authorised EMI. U.S. trust-company and money-transmitter structures do not passport in. Circle’s path was the European one: ACPR EMI licence (July 2024) plus AMF CASP licence (2026) so Circle France can issue and provide custody/transfer. EURC’s share of euro stablecoins has risen sharply under that model. USDT was pulled from major EU venues in late 2024–early 2025 because it was not a MiCA-compliant EMT. That is the GENIUS 2028 distribution ban, two years early.
Reserves and redemption.
EMT: 1:1 in the reference currency, segregated, invested only in highly liquid, low-risk instruments, custody at authorised firms. Holder has an unconditional par redemption right at any time — tighter than OCC Part 15’s two-business-day / seven-day-gate design.
Interest ban is broader than GENIUS.
Article 40 (ARTs) and the parallel EMT rule (Article 50) ban interest paid by issuers and by CASPs. “Interest” includes any remuneration, benefit, discount, or third-party compensation linked to how long the token is held, including pricing of other products that has the same effect. Recital 58 states the purpose: stop the token being used as a store of value. That is the rule U.S. banks want CLARITY to copy. Europe already wrote it. Activity-based merchant rewards that are not duration-linked are the remaining grey zone; hold-to-earn APY on a CASP is not.
Significant tokens.
Cross a size/use threshold and the EBA takes direct supervision, with extra capital, liquidity, stress tests, and recovery planning. Designation is dynamic.
CASPs: Ten Services, One Passport
Authorisation is per service (Article 59). Capital floors scale with the riskiest permission (Annex IV Classes 1–3). Custody and transfer dominate the register (~194 custody permissions vs ~20 trading-platform permissions on an August 2026 tabulation). The industry licensed itself as custodians and brokers with wallets, not as a fleet of European Nasdaq-for-crypto.
Passporting works: one NCA licence, services across the EEA. Lithuania, France, Germany, Luxembourg, Ireland, and Malta have been the practical hubs. Poland is the warning label — no stable national implementing act, presidential vetoes, and after 1 July 2026 no domestic CASP licence path, so firms must passport in from a working member state.
Not yet standalone permissions: staking, lending, and most DeFi. The 2026 Commission consultation asked whether they should be. Until that review becomes law, those activities are either packed into existing services or sit outside the list — which is a supervisory risk, not a free pass.
Travel Rule (TFR, Reg. 2023/1113) has applied to CASP-to-CASP transfers since 30 December 2024. That is the EU twin of the U.S. travel-rule fight, already on.
Market Abuse and White Papers
Title VI imports a MAR-style regime onto crypto: insider dealing, unlawful disclosure, market manipulation. “Inside information” can come from being in the issuer’s board, holding capital, doing a job — or from a role in the DLT itself. Validators and protocol operators are in the factual net even when they are not CASPs.
Title II white papers for “other crypto-assets” are notified, not approved. ESMA’s register is explicit: listing a white paper is not a merit review.
What the 2026 Review Is Probing
The Commission’s targeted consultation (closed 31 August 2026) is the renovation punch list:
- Global / multi-issuance stablecoins (one token, EU and non-EU books)
- Whether EU redemption should be confined to CASP clients, cutting off self-custody wallets
- Capital and reserve calibration for EMTs/ARTs
- Whether the ten-service list is complete
- Staking and lending
- What “decentralized enough” means (identifiable intermediary, identifiable controller)
That last question is CLARITY’s DeFi controller problem in Brussels English.
MiCA vs GENIUS vs CLARITY
| Issue | MiCA (live) | GENIUS (live) | CLARITY (bill) |
|---|---|---|---|
| Dollar/euro payment coin issuer | Bank or EMI only | Bank sub, OCC nonbank, or comparable state | Uses GENIUS category |
| 1:1 public-sector-ish reserves | Yes, highly liquid | Closed T-bill / cash list | n/a |
| Holder redemption | At par, at any time | Statute silent; OCC proposes T+2 / T+7 gate | n/a |
| Issuer yield | Banned | Banned | Banned (already) |
| Platform hold-to-earn | Banned (Art. 40/50 reach CASPs) | Not clearly banned | September draft would ban deposit-equivalent yield, allow activity rewards, add 18-month Treasury switch |
| Venue licence | CASP + passport | DASP distribution rules from 2028 | CFTC digital-commodity intermediaries + SEC |
| BTC/ETH | Other crypto-assets + white paper | Untouched | Digital commodities under CFTC |
| DeFi / admin keys | Consultation, not settled | Protocol carved out of DASP | “Non-decentralized protocol” rules |
| Foreign coin on local venues | Non-compliant EMT/ART off major books | Reciprocity + freeze stack + 2028 ban | Separate |
Investor Implications
- USDC / EURC in Europe are the template of a licensed payment coin. USDT in Europe is the template of a large coin that lost the regulated on-ramp. GENIUS 2028 is that story with a U.S. date stamp.
- Hold-to-earn on EU CASPs is already legally hostile. Do not model European stablecoin APY as a durable coupon.
- COIN, KRKN, Ripple, Circle with EU licences are in the passport club. Firms that missed 1 July 2026 grandfathering and have no passport are out of the regulated EEA shopfront.
- Tokenized securities and RWAs are only partly MiCA. Many sit under MiFID/Prospectus. Do not assume a CASP licence clears a tokenized T-bill fund.
- A U.S. CLARITY failure does not freeze Europe. MiCA plus the 2026 review will keep tightening global-issuance and self-custody redemption. Dollar-coin issuers that want both markets must run two rulebooks: OCC Part 15 / GENIUS at home, EMI + Title IV in Paris or Frankfurt.
DividendChase Read
MiCA is the existence proof that a G-7 bloc can force stablecoins onto a bank-or-EMI licence, ban platform interest, and pull non-compliant dollars off the board without killing BTC spot markets. The U.S. debate is whether to copy the yield ban on distributors (Europe already did) and whether nonbank OCC issuers are allowed (Europe said no). Price European exposure as a licensed-rail market. Price U.S. platform rewards as optional until CLARITY or the OCC close the hole MiCA closed two years ago.
