What Is MiCA?
The EU Markets in Crypto-Assets Regulation sets stablecoin taxonomy, reserve rules, CASP licensing, and passporting across 27 Member States.
Published
MiCA distinguishes EMT from ART, licenses CASPs, creates EU passporting, and turns stablecoin compliance into a market access condition.

Reading Guide
Four moves that explain why MiCA is the most consequential crypto framework in a major economic bloc.
EMT vs ART is the central taxonomy.
EMTs reference a single fiat currency and matter most for payment stablecoins. ARTs reference baskets or other assets and operate mainly as a regulatory perimeter for more complex stablecoin designs.
CASP licensing is the operational gate.
MiCA lists regulated crypto-asset services such as custody, exchange, transfer, advice, and portfolio management. Authorization in one Member State can be passported across the EU.
Significance designation brings EBA and ECB supervision.
Large EMTs and ARTs can become significant based on holder count, market cap, transaction activity, and systemic connections. That moves supervision above the national layer.
The USDT delisting is the market proof.
The source frames EU exchange restrictions on non-authorized USDT as the first regulatory-defined stablecoin market shift: compliance status became a market-access filter.
What MiCA Regulates
Crypto-assets that are not already securities, plus service providers around them.
MiCA starts by sorting assets and services; the stablecoin-specific path sits inside that broader perimeter.
The three crypto-asset categories
**E-Money Tokens (EMT):** stablecoins referencing a single fiat currency. **Asset-Referenced Tokens (ART):** tokens referencing baskets of currencies, commodities, or other assets. **Other crypto-assets:** non-stablecoin crypto-assets subject to disclosure and service rules but not the stablecoin issuer-license regime [1].
The CASP licensing regime
Crypto-Asset Service Providers cover custody, trading platforms, exchange, execution, placing, reception and transmission of orders, advice, portfolio management, and transfer services. CASPs need Member State authorization and can passport across the EU [4].
ART vs EMT
Most cross-border stablecoin operators care primarily about EMT.
For payment operators, the practical split is whether the token references one fiat currency or a broader basket.
| Property | EMT | ART |
|---|---|---|
| Reference | Single fiat currency | Basket of currencies, commodities, or other assets |
| Issuer license | EMI or credit institution | Authorized ART issuer with heavier EBA supervision |
| Capital requirement | EMI standard | Reserve-linked prudential requirement |
| Reserve rule | 1:1 safeguarded funds | Segregated assets matching basket |
| Yield | Prohibited | Prohibited |
| Commercial role | Core payment-stablecoin route | Mostly defensive perimeter today |
Issuer Requirements
Stablecoin issuers do not receive a crypto carve-out from ordinary operational discipline.
Issuer obligations turn stablecoins into supervised operating companies, not just token contracts.
- 1:1 backing in safeguarded reserves
- Segregated accounts or low-risk securities
- Daily reserve verification and periodic disclosure
- Governance, complaint handling, business continuity, ICT risk, and outsourcing controls
Significance designation
EMTs above significance thresholds face heightened supervision by EBA and ECB. The source highlights thresholds such as more than 10 million holders, more than EUR 5 billion in market cap, more than EUR 500 million in average daily transactions, or systemic connections.
CASP Licensing
The bottleneck is operational maturity, not only capital.
Licensing friction shows up in governance, controls, and regulator readiness as much as in capital.
Application process
An operator chooses a Member State, applies to the competent authority, demonstrates management, capital, governance, IT controls, and compliance maturity, then passports through notification. The source treats 6-12 months as realistic and warns that operators should plan 12-18 months when EU corridor access matters.
CASP backlog
Competent authorities processed some applications more slowly than early market expectations. That makes transition planning and regulator selection material operating decisions.
Passporting
One authorization can unlock EU-wide operations, but national supervisory cultures still matter.
A CASP authorized in one Member State can serve clients across other Member States through notification rather than re-licensing. The same logic applies to authorized issuers. This is the EU structural advantage over fragmented licensing models, even when national competent authorities still differ in supervisory style.
Enforcement Timeline
MiCA entered force in phases, and market access now depends on compliance status.
The rollout matters because market access now depends on timing as well as legal category.
| Date | Provisions |
|---|---|
| 30 June 2024 | EMT and ART rules in force |
| 30 December 2024 | CASP rules and consumer-protection provisions in force |
| 2025-2026 | Member-State-dependent transition periods for legacy operators |
| 2026 onward | Full enforcement; non-licensed operators excluded from EU markets |
The USDT exclusion
The source frames USDT EU delistings as the largest regulatory market shift in stablecoin history. The precise exchange-by-exchange status is time-bound and should be refreshed before final CMS publication, but the policy point stands: MiCA turns stablecoin authorization into market access.
