The Markets in Crypto-Assets Regulation (MiCA), Regulation (EU) 2023/1114, is the European Union's harmonised framework for crypto-assets that fall outside existing EU financial services law. It sets uniform rules for the issuance and offering of crypto-assets, their admission to trading, and the provision of crypto-asset services, with the stated aims of consumer and investor protection, market integrity, and financial stability.
MiCA applies across all EU Member States and covers two main groups of actors: issuers and offerors of crypto-assets, and crypto-asset service providers (CASPs) such as exchanges, custodians, and brokers. It applies in phases — rules for asset-referenced tokens (ARTs) and e-money tokens (EMTs) from 30 June 2024, and the remaining provisions, including the CASP regime, from 30 December 2024. ESMA and the EBA develop technical standards and, for significant stablecoins, the EBA exercises direct supervision.
What does MiCA cover, and what is excluded?
MiCA governs the issuing, public offering, and admission to trading of crypto-assets, and the provision of crypto-asset services, where those assets are not already regulated by other EU financial services law.
Key exclusions:
- Crypto-assets that qualify as financial instruments, deposits, pensions, or insurance products (regulated under other EU acts).
- Non-fungible tokens (NFTs) — crypto-assets that are unique and not interchangeable with others.
- Central bank digital currencies and other central-bank-issued instruments.
It applies across all EU Member States, creating a single rulebook in place of fragmented national regimes.
What are the three crypto-asset categories under MiCA?
MiCA distinguishes three categories, each with its own regime:
- Asset-referenced tokens (ART) — a crypto-asset, other than an e-money token, that purports to maintain a stable value by referencing any other value or right, or a combination, including one or several official currencies. Governed under Title III.
- E-money tokens (EMT) — a crypto-asset that purports to maintain a stable value by referencing the value of one official currency (a single-fiat stablecoin). Governed under Title IV.
- Other crypto-assets — all remaining crypto-assets not covered above (e.g. utility tokens). Governed under Title II.
The single-vs-multiple official currency distinction is what separates an EMT from an ART.
What white paper obligations apply?
Most public offerings or admissions to trading require a crypto-asset white paper, published on the issuer's or offeror's website and notified to the competent authority.
Core points:
- The white paper must contain prescribed disclosures so investors can make informed decisions; marketing communications must be consistent with it.
- Issuers and offerors can be held liable for damages for information in the white paper that is incorrect, unfair, unclear, or misleading.
- Requirements differ by category — ART and EMT issuers face additional approval and content obligations beyond those for other crypto-assets.
CASPs are also required to give clients access to relevant white papers as part of their disclosures.
How does CASP authorisation and passporting work?
Providing crypto-asset services in the EU on a professional basis requires authorisation as a CASP (or qualifying as a credit institution or other eligible entity). Applicants apply to the competent authority of their home Member State.
Applications typically cover governance arrangements, a programme of operations, prudential safeguards, custody and client-asset protection, ICT and security, AML/CFT controls, complaints and conflicts-of-interest policies, and fitness-and-propriety of management.
Once authorised, a CASP benefits from the EU passport: it can provide its authorised services across all Member States by notifying its home authority, without separate authorisation in each state.
What are the rules for stablecoins (ARTs and EMTs)?
Issuers of ARTs and EMTs face the strictest requirements under MiCA, reflecting payment and financial-stability concerns.
- Authorisation: ART issuers must be authorised; EMT issuers must be authorised as a credit institution or an electronic money institution.
- Reserves: issuers must maintain adequate, segregated reserve assets backing the tokens, with redemption rights for holders.
- Significant tokens: ARTs/EMTs meeting size and usage thresholds are classified as significant and supervised directly by the EBA, with enhanced requirements.
- Non-euro EMT caps: where a significant token denominated in a non-EU official currency is widely used as a means of exchange, issuance is constrained once usage exceeds EUR 200 million in daily transaction value or 1 million transactions per day within a single currency area.
What market-abuse rules does MiCA impose?
Title VI of MiCA establishes a market-abuse regime for crypto-assets that are admitted to trading, or for which admission has been requested.
It prohibits:
- Insider dealing using inside information.
- Unlawful disclosure of inside information, except in the normal exercise of employment, profession, or duties.
- Market manipulation.
The rules apply broadly — not only to issuers and CASPs but to any person acting in relation to in-scope crypto-assets. Persons professionally arranging or executing transactions must have effective arrangements to prevent and detect market abuse.
When does MiCA apply, and is there a transition period?
MiCA entered into force in 2023 and applies in phases:
- 30 June 2024 — rules for asset-referenced tokens (ARTs) and e-money tokens (EMTs) (Titles III and IV).
- 30 December 2024 — the remaining provisions, including the CASP regime and rules for offerings of other crypto-assets.
Member States may grant a transitional ('grandfathering') period allowing entities that lawfully provided crypto-asset services under national law before 30 December 2024 to continue while seeking MiCA authorisation, up to an EU-wide outer limit of 1 July 2026 (national periods may be shorter). Confirm the exact transitional rule with the relevant national competent authority.
Frequently asked questions
What does MiCA stand for?
MiCA stands for Markets in Crypto-Assets Regulation. Its legal citation is Regulation (EU) 2023/1114, and it sets harmonised EU rules for crypto-asset issuers and service providers.
When did MiCA take effect?
MiCA applies in phases. Rules for asset-referenced tokens (ARTs) and e-money tokens (EMTs) have applied since 30 June 2024, and the remaining provisions — including the crypto-asset service provider (CASP) regime — apply from 30 December 2024.
What is the difference between an ART and an EMT?
An e-money token (EMT) references the value of one official currency (a single-fiat stablecoin). An asset-referenced token (ART) references any other value or right, or a combination — such as multiple currencies, commodities, or other assets — and is not an EMT.
Does MiCA apply to NFTs?
Generally no. MiCA does not apply to crypto-assets that are unique and not interchangeable with other crypto-assets (NFTs). However, assets issued in a large series or that are fungible in substance may still fall in scope; assessment is fact-specific.
What is a CASP and does it get an EU passport?
A crypto-asset service provider (CASP) is an authorised entity providing services such as custody, exchange, or brokerage of crypto-assets. Once authorised in one Member State, a CASP can passport its authorised services across the EU by notifying its home authority, without separate authorisation in each country.
Who supervises significant stablecoins under MiCA?
Asset-referenced tokens and e-money tokens classified as 'significant' (based on size and usage criteria) are supervised directly by the European Banking Authority (EBA), with enhanced capital, liquidity, and reserve requirements. Other issuers and CASPs are supervised by national competent authorities.
