The Markets in Crypto-Assets Regulation (Regulation 2023/1114)
The Markets in Crypto-Assets Regulation (MiCA), formally Regulation (EU) 2023/1114, is the European Union’s comprehensive regulatory framework for crypto-assets, crypto-asset service providers, and stablecoins. Adopted on 31 May 2023 and entering into force in stages through 2024–2025, MiCA establishes uniform rules for the issuance, public offering, and trading of crypto-assets as well as the provision of services related to crypto-assets across the EU. The Regulation aims to provide legal certainty, support innovation, protect consumers and investors, and ensure financial stability in the rapidly evolving crypto-asset market. MiCA replaces the divergent national regulatory approaches that had emerged across Member States and establishes a single rulebook for the EU’s crypto-asset sector.
Scope and Classification of Crypto-Assets
MiCA applies to crypto-assets broadly defined as digital representations of value or rights that may be transferred and stored electronically using distributed ledger technology or similar technology. The Regulation distinguishes three principal categories of crypto-asset. Asset-referenced tokens (ARTs) are crypto-assets that aim to maintain a stable value by referencing another value or right, including multiple fiat currencies, commodities, or a basket of such assets. E-money tokens (EMTs) are crypto-assets that aim to maintain a stable value by referencing a single official fiat currency, functioning as electronic money. Utility tokens are crypto-assets intended to provide digital access to a good or service available on distributed ledger technology, not functioning as a means of payment or store of value. Crypto-assets that qualify as financial instruments, deposits, structured deposits, or securitisation positions under existing EU financial services legislation are excluded from MiCA’s scope and remain regulated under the applicable sectoral regimes.
Stablecoin Regulation: ARTs and EMTs
Asset-referenced tokens and e-money tokens — collectively referred to as stablecoins — are subject to the most stringent requirements under MiCA, reflecting their potential to affect financial stability and monetary sovereignty. Issuers of ARTs must be established in the EU and obtain authorisation from the competent authority, with additional requirements where the ART is “significant” — a classification based on criteria including number of holders, value of the reserve, volume and value of transactions, and interconnectedness with the financial system. Significant ARTs are subject to enhanced supervision by the European Banking Authority (EBA).
Issuers of ARTs must maintain a reserve of assets at least equal to the value of the tokens in circulation, composed of low-risk assets held in custody with a regulated credit institution. The reserve must be segregated from the issuer’s own assets and managed to absorb losses. Holders of ARTs must have a permanent right of redemption at par value. Marketing communications concerning ARTs must be identified as such and must not contradict the information in the white paper.
E-money token issuers must be authorised as credit institutions or electronic money institutions under the Electronic Money Directive (2009/110/EC). EMTs are treated as electronic money and holders have a right to redeem at par value at any time. Significant EMTs are subject to enhanced supervision by the EBA. Prohibitions on granting interest or other benefits to holders of EMTs are maintained to preserve the distinction between crypto-assets and deposits.
Crypto-Asset White Papers
Any person offering crypto-assets to the public or seeking admission to trading on a trading platform in the EU must publish a crypto-asset white paper (Articles 6–19) containing prescribed information: details of the offeror and the issuer, information about the project, the amount of crypto-assets to be offered, the rights and obligations attaching to the crypto-assets, the underlying technology, the risks, and the environmental impact. The white paper must be fair, clear, and not misleading. For offers below €5 million over 12 months, Member States may exempt issuers from the obligation to produce a white paper. White papers for ARTs and EMTs are subject to prior review and approval by the competent authority; white papers for other crypto-assets are notified but not pre-approved.
Crypto-Asset Service Providers
Crypto-asset service providers (CASPs) — entities that provide services such as custody and administration of crypto-assets, operation of trading platforms, exchange services, and advice on crypto-assets — must obtain authorisation from the competent authority of their home Member State. Authorised CASPs may passport their services throughout the EU through the single licence passport. CASPs must comply with organisational requirements, prudential safeguards (own funds requirements of at least €50,000 to €150,000 depending on the type of service), and conduct of business rules including obligations to act honestly and fairly, provide clear information to clients, publish prices, and handle complaints.
CASPs are subject to anti-money laundering and counter-terrorism financing (AML/CFT) obligations under the revised AML framework, including customer due diligence, transaction monitoring, and reporting of suspicious transactions. The Transfer of Funds Regulation (TFR) has been amended to require CASPs to collect and transmit information on the originator and beneficiary of crypto-asset transfers, implementing the “travel rule” recommended by the Financial Action Task Force (FATF).
Market Abuse and Investor Protection
MiCA incorporates rules against market abuse in crypto-assets, including prohibitions on insider dealing, unlawful disclosure of inside information, and market manipulation. Persons discharging managerial responsibilities must notify the competent authority of transactions conducted on their own account. The prohibitions apply to crypto-assets admitted to trading on a trading platform and to any related auction platform.
Regulatory Oversight: ESMA and EBA
The European Securities and Markets Authority (ESMA) is responsible for developing regulatory technical standards and guidelines for crypto-asset markets, maintaining a register of non-compliant CASPs, and coordinating national competent authorities. The EBA is responsible for the supervision of significant ARTs and significant EMTs, exercising direct supervisory powers over their issuers. National competent authorities remain the primary supervisors of CASPs and non-significant crypto-asset issuers.
Enforcement and Penalties
MiCA requires Member States to establish effective, proportionate, and dissuasive penalties for infringements. Maximum administrative fines for natural persons must be at least €700,000 for breaches of ART/EMT provisions and €5,000,000 for legal persons. Member States may also impose periodic penalty payments, public warnings, cease-and-desist orders, and suspension or withdrawal of authorisation. The Regulation entered into force on 29 June 2023, with the stablecoin rules applying from 30 June 2024 and the remaining provisions applying from 30 December 2024.
