MiCA and DeFi Vaults: What the EU Consultation Means for Accounting Teams
The European Commission has opened a targeted consultation asking stakeholders whether crypto lending and decentralised finance should be pulled inside the MiCA regulatory perimeter. For accounting firms, auditors and CFOs who hold or service DeFi positions, the stakes are real: the outcome could transform how lending vault exposures are classified, measured, and disclosed under both IFRS and internal control frameworks. The consultation closes 30 September 2026, and the window to shape the result is short.
Why Lending Vaults Sit Outside MiCA Today
When the Markets in Crypto Assets regulation took effect, crypto lending was deliberately left outside its scope. The Commission's view at the time was that the space was too nascent and too architecturally diverse to regulate cleanly. That position has held, but only because of non-binding interpretations that vault structures fall outside both MiCA and EU fund law. Those interpretations are not legally guaranteed, and Brussels is now formally questioning them.
The "fully decentralised" carve-out
MiCA does include a limited exemption for crypto asset services provided in a "fully decentralised manner." In practice, however, very few protocols meet a strict reading of that test. The regulation is explicit that where any part of an activity is performed in a centralised way, the exemption can fall away. That creates a grey zone that the consultation is, in part, designed to address.
What the May 2026 consultation covers
On 20 May 2026, the European Commission invited stakeholders to comment on areas left outside the original MiCA framework. The two headline topics are DeFi broadly and crypto lending and borrowing specifically. The Commission wants to understand the economic functions these activities perform, who exercises meaningful control over them, and whether existing regulatory categories can accommodate them or whether new ones are needed.
The Vault Architecture Problem
Lending vaults channel capital into on-chain credit markets at scale, sometimes routing billions of dollars, without looking or behaving like a conventional lender. That is precisely the challenge for regulators and, by extension, for accounting teams trying to understand what they are actually holding.
How responsibility is distributed
Decentralised lending infrastructure illustrates why identifying a single "provider" is so difficult. Advanced vault architectures divide responsibility across distinct roles: a curator that sets strategy and risk parameters, an allocator that executes capital deployment, and a sentinel role intended to reduce downside risk. No single participant appears to be providing a regulated lending service as MiCA currently defines it, yet the combined system performs the economic function of credit intermediation.
EU digital assets lawyer Yuriy Brisov, a partner at Digital & Analogue Partners, frames the problem clearly: EU law has no category called a "vault," so a lawyer must define it the way a regulator would qualify it, by function rather than by label. That is not a comfortable starting point for firms that need to map positions to recognised accounting categories.
Not all vaults are the same
Jonathan Galea, a partner at Cahill Gordon & Reindel, has warned policymakers against treating lending vaults as a single regulatory category. His concern is that structures performing very different economic functions could end up captured together under a broad "DeFi lending" label. Some vaults direct fragmented liquidity into lending markets; others buy and sell crypto assets and should be treated differently. Collapsing them into one definition risks producing regulatory outcomes that are simultaneously over-inclusive and under-inclusive.
The Decentralisation Spectrum and Its Accounting Consequences
One proposed solution inside the consultation debate is to use the degree of decentralisation as the dividing line: protocols that are sufficiently decentralised stay outside the perimeter, while those with identifiable control points come in. Galea argues this approach would disadvantage newer protocols that have not yet had time to distribute governance and control, while entrenching mature incumbents. Brisov offers a structural test instead, focusing on whether there is an identifiable undertaking, an appointed manager, and whether users hold a direct coded claim on the pool with the ability to exit before any parameter change takes effect.
From an accounting standpoint, the decentralisation question matters enormously. Where a protocol has identifiable governance participants who exercise discretion over risk parameters, consolidation analysis under IFRS 10 becomes relevant. A firm that holds vault tokens and also sits on a committee with power to redirect capital allocations may face a very different accounting treatment than a purely passive holder. The answer will depend on the specific facts, but the analysis needs to happen now, before any regulatory classification is imposed.
IFRS crypto assets and the classification question
Under IAS 38, most crypto assets held by an entity are treated as intangible assets measured at cost or revaluation. Vault tokens, however, are not straightforward: they represent a proportional claim on a pool of assets that changes in composition over time. Whether a vault token is an intangible asset, a financial instrument, or something else entirely depends on the specific contractual rights it confers. IFRS has not issued definitive guidance on vault tokens specifically, which means preparers must exercise judgment and document their reasoning carefully. If the Commission's consultation results in vault structures being classified as collective investment schemes under EU fund law, IFRS 9 or IFRS 27 may become relevant, potentially requiring fair value measurement and consolidated reporting obligations.
MiCA Compliance: What Firms Need to Assess Now
Even before the consultation concludes, accounting firms, auditors and CFOs should be conducting a structured assessment of their DeFi exposures. The regulatory outcome is uncertain, but the audit and disclosure risks are present today.
Identify and map vault positions
The first step is inventory. Any entity holding vault tokens, providing liquidity to on-chain credit markets, or earning yield from DeFi lending protocols needs a clear record of what it holds, which protocol issued the position, what the underlying assets are, and what rights (if any) the entity holds over governance or parameter-setting. This is foundational for both MiCA compliance analysis and financial statement preparation.
Assess control and consolidation risk
For entities with governance roles in vault structures, IFRS 10 consolidation analysis is not optional. The existence of a sentinel, curator, or allocator role could, depending on the facts, constitute power over relevant activities. Even a minority governance role can trigger consolidation if it amounts to de facto control. Firms advising clients with these exposures should document the analysis and revisit it as governance structures evolve.
Review disclosures and fair value measurement
Where vault positions are material, IFRS 13 fair value disclosures will need to address the specific liquidity characteristics of vault tokens, which may trade in thin or illiquid secondary markets. Level 3 classification is likely for many vault tokens given the absence of observable inputs. The accounting policy note should explain the measurement basis, the key assumptions, and the sensitivity of the valuation to those assumptions. Auditors should be pushing for this level of documentation already, regardless of how the consultation resolves.
Watch the consultation response deadline
The Commission's consultation closes 30 September 2026. Any accounting firm, industry body or CFO with a view on how vault structures should be treated has a narrow window to submit. The framing of a future regulatory instrument, if one is proposed, will be shaped by the quality of the input the Commission receives. Silence is itself a choice, and not a neutral one.
The Broader Regulatory Picture
The MiCA DeFi consultation does not sit in isolation. The EU's broader digital finance agenda includes ongoing work on crypto asset service provider authorisation, stablecoin supervision, and the intersection of DeFi with AML obligations. For firms already navigating MiCA compliance across their crypto portfolios, the lending vault question adds another layer of uncertainty to manage.
Curve Finance founder Michael Egorov has made the point that DeFi lending genuinely differs from conventional finance in ways that matter for regulation. He argues that a dedicated framework, rather than forcing DeFi into existing categories, could improve safety and expand access, provided it avoids imposing requirements that some protocols structurally cannot meet. That view aligns with what several lawyers and protocol developers have submitted informally to Brussels, though whether it translates into policy will depend on political dynamics as much as technical analysis.
For accounting professionals, the practical message is the same regardless of how the political debate resolves: the absence of a final regulatory framework is not a reason to defer the accounting analysis. Vault positions carry measurement uncertainty, consolidation risk, and disclosure obligations that exist independently of what Brussels ultimately decides. Firms that have done the work will be better placed to adapt when the rules arrive, and to defend their positions if they don't.
You can review how the broader EU MiCA authorisation landscape has developed for context on which EU VASPs have been licensed under MiCA and where residual risk sits. For firms also tracking the stablecoin dimension of the DeFi consultation, the earlier analysis of how MiCA is affecting stablecoin accounting teams in Europe provides useful framing.

Frequently Asked Questions
Is MiCA currently applicable to DeFi lending vaults?
Not directly. MiCA includes a carve-out for crypto asset services provided in a fully decentralised manner, and current non-binding interpretations suggest most lending vaults fall outside its scope. However, that position rests on interpretations rather than explicit legal text, and the Commission's 2026 consultation is specifically examining whether lending should be brought inside the regulatory perimeter.
How should vault tokens be measured under IFRS?
There is no specific IFRS guidance on vault tokens. Most entities treat them as intangible assets under IAS 38, but the proportional-pool claim embedded in a vault token may, depending on its contractual terms, point toward a financial instrument classification under IFRS 9. Preparers need to document their classification rationale carefully and consider whether fair value measurement is required or permitted under their chosen policy.
When does IFRS 10 consolidation become relevant for vault positions?
IFRS 10 requires consolidation where an entity has power over the relevant activities of another entity, exposure to variable returns, and the ability to use that power to affect those returns. A vault curator, allocator, or governance participant who can direct capital allocation or change risk parameters may meet the power criterion depending on the specific facts. Firms with such roles should conduct a consolidation assessment and document it.
What is the deadline for the European Commission's MiCA consultation?
The targeted consultation on areas outside the original MiCA framework, including DeFi and crypto lending, closes on 30 September 2026. Accounting firms, industry associations, and affected companies can submit responses directly to the Commission during this period.
How does the decentralisation spectrum affect regulatory classification?
The degree of decentralisation matters because MiCA's carve-out applies only where a service is fully decentralised. Lawyers and protocol developers have flagged that using decentralisation as the primary dividing line creates problems: it would disadvantage newer protocols that have not yet distributed governance, and it rewards incumbents that have had time to do so. A structural test focusing on whether there is an identifiable undertaking and whether users have direct, exitable claims may be more workable, though the Commission has not yet signalled which approach it prefers.
