Quick answer: the line between MiCA and MiFID II comes down to a single question: does the token embed a financial instrument? If it represents a share, a bond, a fund unit or a derivative, it falls under MiFID II (Directive 2014/65/EU) and, in Spain, under Ley 6/2023 (Spain's Securities Markets Law, LMVSI); MiCA is excluded. If it is not a financial instrument, it falls within the scope of MiCA, as an asset-referenced token (ART), an e-money token (EMT) or another crypto-asset (MiCA, Regulation (EU) 2023/1114, Art. 2(4)).
The question that decides the regime
Before looking at the technology, look at the law. MiCA and MiFID II do not overlap: they divide the field according to the legal nature of the token. MiCA governs crypto-assets that are not financial instruments; MiFID II governs financial instruments, whether or not they are represented on a blockchain. MiCA itself says so explicitly: it does not apply to crypto-assets that qualify as financial instruments (Regulation (EU) 2023/1114, Art. 2(4)).
The most common mistake is asking whether a token complies with MiCA before establishing which right it represents. If the token confers a right to dividends, to interest, to a fund unit or to a position in a derivative, it is a financial instrument, and MiCA is not its rulebook. It falls under MiFID II (Directive 2014/65/EU, Annex I, Section C).
Decision tree
- Step 1. Does the token embed a right typical of a financial instrument (a share, a bond, a collective investment scheme unit, an Annex I derivative under MiFID II)? If yes, it is a security token: it falls under MiFID II and the LMVSI; where it is represented through DLT/blockchain, it needs an ERIR (the entity responsible for the registration and recording of DLT-based securities) to keep its register (Ley 6/2023, BOE-A-2023-7053). MiCA does not apply.
- Step 2. If it is not a financial instrument, is it referenced to one or more official currencies? It is an e-money token (EMT), governed by Title IV of MiCA and supervised by the Banco de España.
- Step 3. Is it referenced to a basket of assets, currencies or commodities in order to keep a stable value? It is an asset-referenced token (ART), Title III of MiCA.
- Step 4. Is it none of the above but still a crypto-asset, for example a utility token? It falls within MiCA's general regime for other crypto-assets (Title II), with a white paper obligation and CNMV supervision.
- Step 5. Is it a genuinely unique, non-fungible asset (a true NFT)? It sits outside MiCA, unless in practice it behaves as a fungible series or disguises a financial instrument (Regulation (EU) 2023/1114).
If, after working through this, the classification is still unclear, you are in a grey area: a legal analysis before issuance is advisable, because substance prevails over form (Art. 4 MiFID II).
MiCA and MiFID II, side by side
MiFID II and LMVSI (security tokens)
- What it governs: financial instruments (shares, bonds, fund units, derivatives), including when they are tokenised.
- The rules: MiFID II (Directive 2014/65/EU) and, in Spain, Ley 6/2023 (LMVSI). Prospectus under the Prospectus Regulation (EU) 2017/1129.
- On-chain registration: through an ERIR; the trading infrastructure may rely on the DLT Pilot Regime (Regulation (EU) 2022/858).
- Authority: CNMV.
MiCA (crypto-assets that are not financial instruments)
- What it governs: EMTs, ARTs and other crypto-assets, including utility tokens.
- The rules: MiCA (Regulation (EU) 2023/1114), applicable to EMTs and ARTs from 30 June 2024 and to the rest from 30 December 2024.
- The document: a crypto-asset white paper, not a securities prospectus.
- Authority: CNMV, and the Banco de España for EMTs and ARTs.
Worked examples
- Token over a company's shares: a financial instrument, so MiFID II and the LMVSI apply, with an ERIR. MiCA excluded.
- Tokenised EUR 50M five-year bond: a debt security, so MiFID II and the Prospectus Regulation apply. MiCA excluded.
- Tokenised fund units: a financial instrument (a collective investment scheme), so MiFID II and CIS rules apply. MiCA excluded.
- Euro-referenced stablecoin: an EMT, so Title IV of MiCA and the Banco de España apply.
- Service-access token (utility): another crypto-asset, so Title II of MiCA applies, with a white paper.
Common mistakes
- Believing MiCA governs security tokens. It does not: it excludes them expressly (Art. 2(4)).
- Classifying by the type of blockchain rather than by the right the token embeds.
- Assuming that tokenising avoids prospectus or authorisation obligations. Tokenisation changes the medium, not the nature of the asset.
- Treating as a utility a token that in fact confers economic rights. The CNMV looks at substance.
What this means for you
Classification drives both cost and regulatory path: a prospectus and an ERIR if it is a security; a MiCA white paper if it is a crypto-asset; an additional authorisation if services are also provided. Settling this before you design the token avoids reworking the structure later.
Frequently asked questions
Is a security token governed by MiCA or by MiFID II?
By MiFID II and, in Spain, by the LMVSI. MiCA excludes financial instruments (Regulation (EU) 2023/1114, Art. 2(4)).
What is the ERIR and when is it needed?
It is the entity responsible for the registration and recording of securities tokenised through DLT. Any issuance of blockchain-represented securities in Spain needs one (Ley 6/2023).
Is MiCA already in force?
Yes. The EMT and ART rules apply from 30 June 2024 and the rest from 30 December 2024, with a transitional regime for crypto-asset service providers (CASPs).
Is a stablecoin the same as a security token?
No. A currency-referenced stablecoin is an EMT under MiCA; a security token is a financial instrument under MiFID II.
