MiCA and stablecoins: what issuers need to know
MiCA treats stablecoins as a distinct, higher-risk category of crypto-asset and imposes its most demanding requirements on their issuers. This guide covers the ART and EMT classifications, reserve requirements, redemption rights, and what the significant token designation means in practice.
Why stablecoins get their own regulatory treatment
The Markets in Crypto-Assets Regulation (MiCA), Regulation (EU) 2023/1114 (CELEX: 32023R1114), covers a wide range of crypto-assets and the firms that issue or service them. But within that framework, stablecoins occupy a distinct and more demanding tier. They came into force six months ahead of the broader CASP provisions, in June 2024, reflecting the EU’s view that stablecoins present systemic risk that general crypto-assets do not.
The concern is straightforward. A widely adopted stablecoin used for everyday transactions can, in practice, function as a parallel payment instrument at scale. If a large stablecoin fails to maintain its peg, or if redemptions cannot be met, the consequences extend beyond the token’s holders into the broader financial system. MiCA’s stablecoin framework is a direct response to that risk: it applies bank-like prudential requirements to stablecoin issuers and places the most significant ones under direct European Banking Authority (EBA) supervision.
MiCA does not use the term “stablecoin” as a legal category. Instead it defines two regulated token types: asset-referenced tokens and electronic money tokens. Understanding which category applies to a given token is the first compliance question any issuer must answer, because the obligations that follow are materially different.
For context on MiCA’s overall scope and the CASP framework, see what is MiCA and who does it affect. For the authorisation process specific to crypto-asset service providers, see MiCA for crypto asset service providers: what authorisation actually requires.

The two classifications: ART and EMT
Asset-referenced tokens
An asset-referenced token (ART) is a crypto-asset designed to maintain a stable value by referencing one or more assets, or a combination of assets. The reference may include fiat currencies, commodities, or other crypto-assets, but it is not pegged to a single fiat currency. Stability is achieved through exposure to a composite reference rather than a one-to-one currency peg.
Typical ART structures include tokens referencing a basket of fiat currencies, a combination of fiat currencies and commodities such as gold, or non-currency assets alone. The defining feature is the basket or composite reference. A token that references only the euro is not an ART under MiCA; it is an electronic money token.
Only EU-established legal persons may issue ARTs. A non-EU entity cannot become an ART issuer; it would need to establish an EU legal entity and obtain authorisation before bringing an ART to market.
Electronic money tokens
An electronic money token (EMT) is a crypto-asset that maintains a stable value by referencing a single fiat currency. The practical effect is to make EMTs digital representations of fiat money: a euro-referenced EMT is the regulatory equivalent of electronic money in token form.
Because of that equivalence, only credit institutions and electronic money institutions (EMIs) may issue EMTs under Article 48 of MiCA. This is the most significant structural difference from the ART regime, where a broader range of EU-established legal persons can obtain authorisation. To issue an EMT, a firm must either already hold a banking or EMI licence, or obtain one. The stablecoin authorisation and the payment institution authorisation are not separate tracks that can be pursued independently.
Why the distinction matters
The classification is not merely taxonomic. It determines who can issue, which regulator supervises, what reserve rules apply, and what the token’s holder rights look like in practice. A firm that misclassifies its token at launch, and then builds a business model and reserve structure around the wrong category, faces a significant remediation problem when the error is identified.
Where the classification of a proposed token is genuinely ambiguous, the question should be resolved with legal advice before any public offering is made and before any authorisation application is submitted. NCAs are not obliged to accept a reclassification after authorisation has been granted.
Authorisation requirements
For ART issuers
Non-bank ART issuers must obtain authorisation from the national competent authority (NCA) of their home member state. The authorisation process is comparable in scope and depth to a full financial services licence application. The applicant must demonstrate governance readiness, capital adequacy, reserve management capability, and operational resilience before the NCA will grant authorisation.
The application must include, among other things: a programme of operations describing the proposed ART and its issuance mechanics; a white paper meeting the content requirements specified in MiCA’s Level 2 technical standards; detailed governance documentation including fit and proper assessments for management body members; an AML and counter-terrorist financing programme mapped to the issuer’s specific onboarding and transaction flows; and a complete description of the reserve structure.
One exemption applies: ARTs offered exclusively to qualified investors, or where the total average outstanding value does not exceed EUR 5 million over a 12-month period, are exempt from the full authorisation requirement under Article 16(2) of MiCA. Issuers in this category must still notify the competent authority and publish a white paper, but they do not need prior authorisation. This exemption is narrow and its conditions must be monitored on an ongoing basis. An issuer whose token grows beyond the threshold is no longer exempt.
Credit institutions issuing ARTs do not need a separate MiCA authorisation, but they must comply with notification requirements and ongoing MiCA obligations applicable to ART issuers.
For EMT issuers
As noted above, only credit institutions and EMIs may issue EMTs. The practical implication is that the authorisation question for EMT issuers is usually a question about the entity’s existing licensing status, not the MiCA authorisation process in isolation.
An EMI issuing an EMT must notify its supervisory authority and publish a compliant white paper before the public offer begins. The MiCA obligations then layer on top of the EMI’s existing regulatory requirements: reserve rules, redemption rights, and recovery and redemption planning all apply, in addition to the conduct and governance obligations the entity already carries.
Reserve requirements
The reserve rules are where MiCA’s stablecoin framework most visibly diverges from the general crypto-asset regime, and they are among the most consequential requirements for issuers to understand before structuring a product.
EMT reserves
EMT issuers must hold reserves equal to the value of outstanding tokens at all times. At least 30 percent of reserves must be held as deposits at credit institutions. The remainder may be invested in highly liquid financial instruments with low market, credit, and concentration risk, with a weighted average maturity not exceeding three months for non-significant EMTs.
The EBA’s regulatory technical standards on reserve liquidity set a daily liquidity floor: issuers must be able to meet redemptions at any point without requiring prior notice or conversion of illiquid assets. This is a practical constraint on how reserve assets can be structured, not just a compositional requirement.
ART reserves
ART reserve requirements follow the same general principles but with category-specific overlays that reflect the more complex reference structures involved.
A commodity-backed ART must hold the underlying commodity in custody with a regulated custodian, with daily inventory reconciliation and periodic third-party audit requirements. A multi-currency ART must hold each reference currency in proportion to the basket weights specified in the white paper, with rebalancing rules disclosed.
For all ART issuers, at least 30 percent of reserves must be held as deposits at credit institutions. Reserve assets must be segregated from the issuer’s own assets and held in a manner that protects token holders in an insolvency scenario.
The interest prohibition
One feature of the MiCA stablecoin regime that has material implications for certain business models: issuers are prohibited from paying interest to holders of ARTs or EMTs. This is an explicit provision in MiCA, not an interpretation. Yield-bearing stablecoin structures that remunerate holders directly from the reserve are not permissible under the framework. Issuers whose existing or planned product designs include holder remuneration need to restructure before seeking authorisation.
Redemption rights
Both ART and EMT holders have a direct redemption right from the issuer. Token holders can require the issuer to redeem their tokens at par value. For EMTs, this means redemption at the face value of the referenced fiat currency. For ARTs, redemption must be at the current value of the reference basket.
The redemption right is not contingent on market conditions or secondary market liquidity. Issuers cannot structure a product that withholds or delays redemption except under explicitly defined circumstances set out in the approved white paper, and those exceptions are subject to regulatory scrutiny.
To operationalise redemption rights, MiCA requires all ART and EMT issuers to draw up and maintain both a recovery plan and a redemption plan. The recovery plan sets out how the issuer would survive a severe financial stress event. The redemption plan details the exact procedures for how holders can redeem their tokens for the underlying assets, ensuring that the redemption right can be exercised in practice rather than just on paper. Both documents must be submitted to the competent authority.
Significant token designation
The most consequential tier within MiCA’s stablecoin framework is the significant token designation. ARTs and EMTs can be classified as significant by the EBA when they meet at least three of the criteria specified in Article 43(1) of MiCA and further detailed in Commission Delegated Regulation (EU) 2024/1506.
The quantitative significance thresholds are:
- More than 10 million token holders
- Outstanding value, market capitalisation, or reserve size exceeding EUR 5 billion
- More than 2.5 million transactions per day averaging more than EUR 500 million in daily volume
Two further qualitative criteria relate to the interconnectedness of the issuer’s activities with the financial system and the international scale of those activities. An EBA assessment against all five criteria determines significance.
The significance designation changes both who supervises and what is required.
Supervisory consequences
For significant ARTs, the EBA takes over direct supervision from the home NCA. For significant EMTs, the EBA and the home NCA supervise jointly: the EBA takes responsibility for compliance with the additional requirements applicable to significant tokens, while the NCA retains responsibility for the underlying EMI obligations.
The EBA establishes a supervisory college for each significant ART and EMT issuer. The college includes the home NCA, relevant national authorities from member states where the token is widely held or used, and the ECB in appropriate cases.
Additional obligations for significant issuers
Significant ART issuers face capital requirements scaled to their reserve size, set at 3 percent of average reserve assets. This is higher than the standard requirement of 2 percent.
Significant EMT issuers must hold higher capital buffers, conduct more frequent reserve attestations, and meet interoperability requirements that enable holders to transfer to another significant EMT through standardised interfaces.
The most consequential operational constraint on significant tokens denominated in non-EU currencies is the transaction volume cap. A significant EMT referenced to a non-EU fiat currency, such as a dollar-referenced stablecoin, is subject to a hard cap of 1 million transactions per day or EUR 200 million in daily transaction volume, whichever threshold is reached first, when used as a means of exchange within the EU. This cap is an explicit mechanism for protecting EU monetary sovereignty. It does not apply to the token being held as a store of value or to transactions through crypto-asset venues for trading purposes.
For large non-EU stablecoin issuers, the significance designation and the associated volume cap represent a genuine commercial constraint that must be factored into EU market strategy before entry, not after.
What to watch in 2026
The ART and EMT provisions of MiCA entered into force in June 2024. The framework is now past its first full year of operation, and the EBA’s supervisory priorities for 2026 signal where active attention is being directed.
EBA supervisory priorities for 2026 include ongoing offsite and onsite supervisory activities for significant ART and EMT issuers, with particular focus on reserve composition, liquidity management, and governance of multi-issuance models. The intersection of PSD2 and MiCA for EMT issuers remains an area of interpretive development, particularly where EMT transfer architectures involve the movement of fiat funds.
The EBA published opinions in October 2025 on proposed Commission amendments to the reserve liquidity technical standards, signalling continued regulatory development in this area. The liquidity requirements for reserve assets are not static, and issuers should monitor EBA publications for changes to the instruments that qualify as highly liquid financial instruments for reserve purposes.
For non-EU stablecoin issuers with EU market ambitions, the question of the significance designation and the volume cap requires early analysis. A stablecoin approaching significance thresholds should understand the supervisory and commercial consequences before crossing them.
The intersection of MiCA with the Digital Euro project is also a developing area. The ECB moved to the next phase of the Digital Euro project in October 2025. The relationship between central bank digital currency and MiCA-regulated EMTs will shape the regulatory landscape for euro-referenced stablecoins over the medium term.
