The essentials
- The European crypto-asset regulation applies by exclusion: first you check whether the token is a financial instrument.
- Two tests decide it: negotiability and fungibility. Restricting transfers technically does not avoid classification as a transferable security.
- In a hybrid token the financial instrument nature prevails. There is no mixed regime and no proportional split.
- The classification is documented in writing, with the criteria applied and the elements that would change it if they changed.
The principle: the crypto-asset regime is residual
The European regulation on markets in crypto-assets does not apply to crypto-assets that qualify as financial instruments. Those sit under MiFID II and, in Spain, under Law 6/2023.
The relationship between the two regimes is not one of choice but of exclusion. First you check whether the token is a financial instrument. If it is, the crypto-asset regulation does not come into play. If it is not, you examine whether it fits one of its categories: an asset-referenced token, an electronic money token or the rest of crypto-assets.
In March 2025 ESMA published its guidelines on the conditions and criteria for qualifying a crypto-asset as a financial instrument. They are the reference document for this classification across the European Union.
The four possible fits
| Category | What is assessed | Typical example |
|---|---|---|
| Transferable security | Three cumulative conditions: that it is not an instrument of payment, that it belongs to a class of securities and that it is negotiable on the capital market | Tokenised shares or bonds |
| Money market instrument | Features comparable to treasury bills or certificates of deposit, with short-term repayment and a predefined maturity | Tokenised commercial paper |
| Unit in a collective investment undertaking | Capital from several investors pooled together, a defined investment policy, a collective return and no day-to-day control by the unitholders | Tokenised investment vehicles |
| Derivative | A future commitment, a value derived from an underlying and settlement arrangements in line with MiFID II | Perpetual futures, options, swaps |
The two tests that decide most cases
Negotiability. The token must be capable of being transferred. ESMA clarifies a point that is often misread: restrictions on transfer, such as whitelists of authorised addresses or geographical limitations, do not in themselves rule out negotiability. The assessment is case by case. An issuer does not avoid classification as a transferable security by adding a technical restriction on transfers.
Fungibility and standardisation. Tokens of the same class must be interchangeable and confer the same rights: the same dividend or coupon, the same vote, the same position on a winding-up. It is the feature that turns an individual contract into a class of securities.
A general criterion operates over both: technological neutrality and substance over form. The digital format does not change the classification, and the label the issuer puts on the token is not decisive. A tokenised financial instrument is still a financial instrument, and calling it something else in the marketing material does not change the applicable regime: it only adds a problem with the information given to the investor.
Where each type of token sits
| Type | Usual regime | Note |
|---|---|---|
| Tokenised shares or bonds | MiFID II and Law 6/2023 | They require a registry entity, an issuance document and, where applicable, a prospectus |
| Unit in an investment vehicle | MiFID II and collective investment legislation | May require an authorised management company |
| Electronic money token | The crypto-asset regulation | Referenced to an official currency |
| Asset-referenced token | The crypto-asset regulation | Referenced to a basket |
| Utility or consumption token | The crypto-asset regulation, with transparency obligations | Crosses the line if it incorporates rights of a financial nature |
| Unique NFT | Outside that regulation, unless it fits as a financial instrument | Depends on the uniqueness test |
The three grey areas
Utility tokens. Giving access to a service, a discount or a feature does not turn a token into a financial instrument, not even when buyers speculate on its price rising. The buyer's expectation is not the criterion; the right embedded in it is. A utility token crosses the line when it reproduces rights typical of a security: a share in profits, a corporate vote or a commitment to a financial return.
The usual mistake is to design a utility token and then, to sell it better, communicate it as an investment with a return. That communication does not change the nature of the token, but it can turn the transaction into an irregular offer of securities.
Hybrid tokens. When a token combines features of a financial instrument with utility functions, the financial instrument nature prevails. There is no proportional split and no mixed regime: it is enough for the financial component to be substantively present for it to pull the whole thing along.
NFTs and fractionalised NFTs. A genuinely unique and non-fungible NFT falls outside the crypto-asset regulation. The test ESMA applies is that of interdependent value: if the unique features of the asset contribute to an intrinsic value that is not comparable with that of other assets, there is uniqueness.
Fractionalised NFTs do not inherit that uniqueness automatically. You have to check whether the fractions represent a partial interest in a unique asset, whether they share identical attributes with each other and whether they can be recombined to reconstitute full ownership. When the fractions are identical to each other and negotiable, they look far more like a class of securities than like a unique work.
What happens if the classification is wrong
The consequences are not gradual. Classifying a token wrongly means having operated for months under the wrong regime.
| Scenario | Consequence |
|---|---|
| What was a transferable security was treated as a crypto-asset | A public offer of securities with no prospectus and no applicable exemption, no registry entity and none of the intervention required in the placement |
| It was marketed without the corresponding licence | Provision of investment services without authorisation |
| Marketing material was distributed without controls | Issuer liability for the information addressed to the investor |
| What was not a financial instrument was classified as one | Unnecessary cost and timeline, and a structure oversized for the product |
The last row is less serious but more frequent than it looks. Not every tokenisation needs the full apparatus of the securities market. A loyalty programme with a token is not an issuance, and treating it as one is throwing money away.
How the classification is documented
It is not an internal opinion or a box on a slide. It is a document that has to be capable of being shown to a supervisor, a bank, an institutional investor or an auditor, with four contents.
- An exact functional description of the rights the token embeds, drafted from the contract and the code, not from the marketing material.
- A reasoned application of ESMA's criteria, category by category, including the ones ruled out and why.
- A conclusion on the applicable regime and on the licences and entities it requires.
- The elements that, if they changed, would change the classification. It is the section most often left out and the most useful: a feature added in version two of the product can reclassify everything.
Signed by a law firm, dated and filed. It costs a few thousand euros and it is the piece that lets you answer in ten minutes a question that, without it, takes weeks.
Three questions that settle almost every case
- Does the holder have a right to a financial return, to a share in results or to the repayment of a principal? If yes, it is almost certainly a financial instrument.
- Are the tokens of the same series interchangeable and do they confer identical rights? If yes, there is a class of securities.
- Can it be transferred to a third party, even with restrictions? If yes, there is negotiability.
Three yeses point to MiFID II and Law 6/2023. Three noes point to the crypto-asset regulation or outside both regimes. The combinations in between are exactly the cases where you pay for the legal opinion instead of deciding internally.
Frequently asked questions
Is a token that gives access to a service a financial instrument?
Not on its own. Giving access to a service or a discount does not turn a token into a financial instrument, even if buyers speculate on its price. It crosses the line when it embeds rights typical of a security: a share in profits, a corporate vote or a commitment to a return.
Can I stop my token being a security by restricting transfers?
Not reliably. ESMA points out that restrictions on transfer, such as whitelists or geographical limitations, do not in themselves rule out negotiability. The assessment is case by case and looks at substance, not at the technical barrier.
Which regime applies to a token that is half utility and half investment?
The financial instrument nature prevails. There is no mixed regime: if the financial component is substantively present, it pulls the whole thing into the securities markets regime.
And fractionalised NFTs?
They do not automatically inherit the uniqueness of the original NFT. You have to check whether the fractions represent a partial interest in a unique asset, whether they share identical attributes and whether they can be recombined. When they are identical to each other and negotiable, they look like a class of securities.
