Markets in Crypto-Assets Regulation
MiCA
The world's first comprehensive regulatory framework for crypto-assets. Fully applicable since 30 December 2024, MiCA establishes harmonised EU rules for the issuance, offering, and trading of crypto-assets, the authorisation of crypto-asset service providers, and the supervision of stablecoin issuers -- replacing a fragmented patchwork of 27 national regimes with a single rulebook.
MiCA is the EU's answer to a simple question: how do you regulate crypto without killing it? Before MiCA, each of the 27 EU member states had its own rules -- or none at all -- for crypto exchanges, token issuers, and stablecoin providers. That patchwork meant a company licensed in one country might be operating illegally in another. MiCA replaces all of that with a single EU-wide rulebook that has been fully in force since 30 December 2024.
If you run a crypto exchange, custody platform, or advisory service in the EU, you now need a formal licence called a CASP authorisation. The good news is that once you have it in one member state, you can passport it across the entire EU. The less good news is that the application process is thorough, capital requirements are meaningful, and you must comply with the Travel Rule for every single transfer -- no minimum threshold.
Stablecoin issuers face the tightest rules. If your token is pegged to a currency, the issuer must hold an e-money or credit institution licence and back every token with fully segregated, liquid reserves. Tether has not obtained such a licence, which is why USDT was delisted from most EU-regulated exchanges in late 2024 -- one of MiCA's most visible real-world impacts so far.
For everyone else in crypto -- utility token issuers, NFT projects, DeFi protocols -- MiCA's reach depends on the specifics. Utility tokens need a white paper but no licence. Truly unique NFTs are excluded. Fully decentralised protocols without an identifiable operator are currently outside scope, though the Commission's expected MiCA 2 proposal may change that. The bottom line: if you touch crypto and serve EU customers, MiCA is now the baseline you must meet.
Switzerland has its own well-regarded crypto framework -- the DLT Act (2021) and FINMA's licensing regime -- which predates MiCA and is widely seen as one of the more progressive in Europe. Swiss crypto companies do not need MiCA authorisation to operate domestically. However, any Swiss CASP actively soliciting or serving customers in the EU will likely need to obtain MiCA authorisation in a member state, as MiCA applies to services provided to EU-based clients regardless of where the provider is established.
The practical impact is significant for Swiss exchanges, custodians, and stablecoin projects with EU ambitions. The CASP passporting regime -- one licence for the entire EU -- is a strong incentive for Swiss firms to set up an EU subsidiary and obtain authorisation. Swiss-issued stablecoins referencing EUR or USD will need to comply with MiCA's reserve and redemption requirements if offered to EU residents. Swiss firms should also monitor the MiCA 2 discussions, which may further clarify the treatment of DeFi and cross-border service provision.
MiCA divides crypto-assets into three regulated categories plus an explicit out-of-scope carve-out. Correct classification determines which obligations apply.
MiCA defines ten categories of crypto-asset services. Each requires CASP authorisation from a national competent authority. Authorisation in one Member State passports across the entire EU.
The stablecoin framework is MiCA's most prescriptive regime, designed to prevent a Terra/Luna-style collapse. ARTs and EMTs face strict reserve, redemption, and capital rules.
MiCA's stablecoin provisions triggered the most visible market disruption: the widespread delisting of USDT (Tether) from EU-regulated exchanges.
All crypto-asset offers to the public must be accompanied by a white paper -- MiCA's equivalent of a securities prospectus. The process differs by token type.
Prepare the crypto-asset white paper containing all disclosures required by MiCA Annex I (for other crypto-assets), Annex II (for ARTs), or Annex III (for EMTs). Include project description, rights and obligations, technology used, risks, and the issuer's financial information.
Review the white paper for compliance with MiCA content requirements. The white paper must contain a clear warning that the crypto-asset may lose its entire value, that it is not covered by deposit guarantee schemes, and that investors may have no recourse.
Notify the competent authority of intention to offer by submitting the white paper and any marketing communications. Authority has 20 working days to request amendments for other crypto-assets. ARTs require authorisation (longer timeline).
Publish the white paper on the issuer's website before the start of the public offering or admission to trading. Must remain available for as long as the crypto-asset is held by the public.
Update the white paper whenever a significant new factor, material mistake, or material inaccuracy arises that could affect the assessment of the crypto-asset. Publish modified white paper and notify the competent authority.
The issuer is liable for damages arising from misleading, inaccurate, or inconsistent information in the white paper. This right cannot be waived by contract. Limitation period: at least 12 months from publication.
MiCA Title VI brings crypto-asset markets under a market abuse regime modelled on MAR (Market Abuse Regulation) for traditional securities. Four pillars of prohibition.
MiCA splits supervisory responsibility between ESMA, EBA, and national competent authorities. The division depends on the type of entity and significance of the token.
