MiCA versus MiFID: Fluid Boundaries and the Risk of Double Qualification for Tokenised Assets
Designed as parallel regimes, MiCA and MiFID collide when assets are tokenised: the same digital container can carry rights that drift between “crypto-asset” and “financial instrument,” creating unstable boundaries and the prospect of double qualification.
Tokenisation exposes a structural fault line in EU financial regulation. MiFID classifies instruments by the rights they embody; MiCA classifies tokens by what they are not and by how they move on distributed ledgers. When those logics meet, tokenised assets can slip, overlap or oscillate between regimes, with real consequences for issuers, CASPs and investors.
Introduction
The coexistence of the Markets in Crypto-Assets Regulation (MiCA) and the MiFID II framework constitutes one of the most complex and structurally unstable elements of the European Union’s digital asset regulatory architecture. Although the two instruments are designed to operate in parallel—MiCA covering crypto-assets that do not qualify as financial instruments, and MiFID governing financial instruments regardless of technological form—the practical interaction between them reveals shifting boundaries, conceptual tensions and legal uncertainties. Tokenised assets challenge the neat separation that legislators attempted to create, because tokenisation disrupts the conventional assumptions underlying both regimes: the definition of instruments, the nature of rights, the relevance of technology and the meaning of markets.
MiCA and MiFID embody two different regulatory logics. MiFID rests on a substantive, rights-based taxonomy of instruments, rooted in the economic function of securities, derivatives and structured products. MiCA, by contrast, adopts a residual and technologically anchored approach: it captures digital representations of value that do not fall within MiFID, provided they circulate on distributed ledgers. These divergent conceptual foundations set the stage for friction. A token can be technologically identical whether it represents a utility right, a governance right or a transferable security. The legal regime, however, shifts depending on the economic function attributed to the token by the issuer, by market behaviour or by supervisory interpretation.
This article argues that the boundary between MiCA and MiFID is inherently unstable, not because of legislative oversight, but because tokenisation fundamentally undermines the traditional distinction between financial instruments and non-financial digital assets. As a result, numerous tokenised assets risk falling into a zone of dual interpretive vulnerability where they could, depending on context, fall under both frameworks or oscillate between them. This dynamic creates an environment of legal uncertainty for issuers, service providers and investors, and raises structural concerns about regulatory arbitrage and coherence.
I. Divergent Regulatory Foundations: Residual versus Substantive Classifications
MiFID II relies on a taxonomy that identifies financial instruments based on the rights they embody. Shares, bonds, transferable securities, units in collective investment undertakings and derivatives each correspond to specific economic functions and legal characteristics. The technology through which these instruments are represented is immaterial. A financial instrument remains a financial instrument whether embodied in paper form, an electronic registry or a distributed ledger.
MiCA, however, adopts a fundamentally different approach. Its scope is defined through exclusion: any digital representation of value or rights on a distributed ledger constitutes a crypto-asset unless it is already classified as a financial instrument, an e-money instrument or another regulated category. The law thereby constructs a residual normative perimeter, capturing assets by virtue of their technological form rather than their substantive economic function.
This asymmetry creates conceptual instability. MiFID categories are substantive and timeless, grounded in long-standing doctrines of patrimonial rights. MiCA categories are functional and technologically anchored, reflecting a contemporary attempt to regulate the rapidly evolving crypto-asset ecosystem. The boundary between the two thus relies on interpretive acts that classify a token’s embedded rights, its economic purpose and its structural design.
Tokenisation destabilises this classification process. When the same technological container—the token—can represent vastly different types of rights, the determination of regulatory perimeter becomes a matter of interpretive nuance rather than structural clarity. This creates fertile ground for boundary friction, particularly for hybrid, multi-use or evolving tokens.
II. Tokenisation and the Emergence of Hybrid Assets: The Structural Challenge to Regulatory Distinction
Tokenisation allows for the digital representation of rights that previously belonged to distinct legal categories. A token may initially represent an access right to a platform, but evolve to carry governance rights, revenue-sharing functions or speculative value. Conversely, a token representing a share may incorporate utility features, confusing its classification.
The hybridisation of token functions creates an unprecedented challenge for regulatory regimes that depend on stable distinctions. Under MiFID, a transferable security is defined by substantive rights such as participation in profits or voting rights. Under MiCA, a utility token is defined by its ability to provide access to a service. But what happens when a utility token is traded widely and acquires investment-like characteristics? Or when a governance token functions economically like equity? The classification oscillates between MiFID and MiCA, depending on whether the economic substance or the technological form is prioritised.
Hybrid tokens illustrate the difficulty of maintaining a binary regulatory system in a programmable environment. Token rights are not static; they may be expanded, restricted or reconfigured by community decisions, code modifications or secondary market practices. This dynamism creates a moving boundary between the two legal regimes, where interpretation must accommodate fluidity rather than stability.
III. The Risk of Double Qualification: A Doctrinal and Practical Vulnerability
The friction between MiCA and MiFID gives rise to the possibility that certain tokenised assets may fall simultaneously within both regimes or may be reclassified after issuance. A token initially presented as a utility token may, through market behaviour or issuer practice, satisfy MiFID criteria for financial instruments. Conversely, a token that appears to be an investment instrument may lack essential financial rights, prompting its treatment under MiCA instead.
This double qualification risk carries significant implications. For issuers, it introduces uncertainty about disclosure requirements, authorisation obligations and liability exposure. An issuer that mistakenly categorises a token as non-financial may find itself retroactively subject to MiFID’s stringent prospectus, governance and conduct norms. For service providers, the ambiguity affects licensing, as operating a CASP under MiCA is fundamentally distinct from operating an investment firm under MiFID. For investors, the risk is informational: the rights they acquire may change classification depending on the regulatory perspective adopted by supervisory authorities.
Double qualification also poses institutional challenges. Enforcement authority may shift between national financial supervisors and authorities responsible for crypto-asset oversight. A token that crosses the regulatory boundary disrupts harmonisation and undermines the internal logic of both regimes. The absence of bright-line criteria means that the risk of inconsistent classification across Member States is real, opening the door to regulatory fragmentation.
IV. Supervisory Interpretation and the Role of ESMA: Stabilising or Deepening the Boundary Tension?
MiCA recognises that interpretive uncertainty is inevitable and grants supervisory authorities significant discretion to determine whether a token falls under MiCA or MiFID. ESMA is tasked with issuing guidelines to facilitate consistent classification across the Union. Yet supervisory discretion, while useful for adapting the law to technological evolution, also introduces variability.
In practice, authorities may rely on economic function, market behaviour or issuer intention when classifying tokens. This multifactorial approach enhances flexibility but diminishes predictability. For instance, tokens that incorporate governance rights or revenue streams may be classified differently depending on their prominence within the token’s economic model. Even identical tokens could face divergent classification if used differently by their communities or integrated differently into financial ecosystems.
ESMA’s role is therefore pivotal. Its interpretive guidance will define the effective boundary between MiCA and MiFID. But this centralisation of authority also reveals the instability of the underlying legal architecture: if classification depends on supervisory interpretation rather than intrinsic characteristics, the boundary is inherently fluid.
Conclusion
The juxtaposition of MiCA and MiFID exposes an unavoidable tension within the European digital asset framework. MiFID is grounded in substantive legal rights; MiCA in technological form. Tokenisation, with its capacity to blur economic functions and embed multiple rights within the same digital container, destabilises the clarity of this distinction. As a result, the boundary between the two regimes is not fixed but contingent, interpretive and dynamic.
The risk of double qualification for tokenised assets is not a marginal concern; it is a structural feature of a regulatory ecosystem attempting to map traditional legal categories onto programmable, multi-layered digital instruments. Unless the EU rethinks the conceptual foundations of asset classification—moving toward a functional, technologically aware taxonomy—the boundary between MiCA and MiFID will continue to shift unpredictably.
What emerges is a picture of regulatory convergence shaped not by deliberate harmonisation but by the intrinsic ambiguity of tokenised rights. In this sense, the friction between MiCA and MiFID is not a failure of drafting but a symptom of a deeper doctrinal challenge: the difficulty of governing digital assets through analog categories whose conceptual foundations predate programmable finance.
Key takeaway. The MiCA/MiFID boundary is less a bright legal line than a moving interpretive frontier: in a world of tokenised, hybrid rights, the same asset can slip between “crypto-asset” and “financial instrument,” exposing market actors to double qualification risks and a permanently fluid perimeter.
