MiCA Stablecoin Rules: ART and EMT Regulation Explained

MiCA stablecoin regulation governs every fiat-pegged token offered to the public in the European Union. Under Regulation (EU) 2023/1114 (MiCA), a stablecoin is classified as either an e-money token (EMT), pegged to one official currency, or an asset-referenced token (ART), pegged to a basket or other value. That single split decides who may issue the token, how it is redeemed, and who supervises it.

This page explains the rules precisely, citing the article numbers in the MiCA text itself. It covers the ART versus EMT definitions, issuer eligibility, the reserve and own-funds requirements, redemption rights, the no-interest rule, when a stablecoin becomes "significant" and passes to European Banking Authority supervision, the distinctive non-euro usage cap, and when the rules started to apply. The aim is to give founders, compliance officers and would-be issuers an authoritative reference before they decide whether and where to seek authorisation.

What MiCA stablecoin regulation means (and the ART vs EMT split)

MiCA is the Markets in Crypto-Assets Regulation, Regulation (EU) 2023/1114. It regulates stablecoins through two distinct regimes: Title III governs asset-referenced tokens (Art. 16 to 47) and Title IV governs e-money tokens (Art. 48 to 58). A stablecoin is an EMT if it references one official currency, or an ART if it references a basket or any other value. This classification is the fork on which the entire stablecoin regime turns.

The terms are not interchangeable marketing labels. They are defined legal categories in Art. 3 of MiCA, and the category a token falls into determines its issuer eligibility, its reserve and own-funds obligations, its redemption mechanics and its supervisory authority. Getting the classification right is the first compliance decision any stablecoin project must make.

Asset-referenced token (ART) defined

An asset-referenced token is defined in Art. 3(1)(6) of MiCA as a crypto-asset that is not an e-money token and that purports to maintain a stable value by referencing another value or right, or a combination of them, including one or several official currencies. In practice that means a token backed by a basket: multiple currencies, a commodity such as gold, other crypto-assets, or a mix. If a token is pegged to anything other than exactly one official currency, it is an ART.

E-money token (EMT) defined

An e-money token is defined in Art. 3(1)(7) of MiCA as a crypto-asset that purports to maintain a stable value by referencing the value of one official currency. A euro-pegged coin or a USD-pegged coin is an EMT. The regulation treats an EMT essentially as electronic money in token form, which is why only e-money issuers and banks may issue one.

Why the classification matters

The ART versus EMT distinction is not academic. It drives three things at once: who is allowed to issue the token, how holders may redeem it, and which authority supervises the issuer. An EMT can be issued only by a credit institution or an authorised electronic money institution, and is redeemable at par. An ART can be issued by a wider class of EU-authorised issuer, but is redeemable at the market value of its reserve rather than at par. Every other rule on this page flows from this initial classification.

ART vs EMT at a glance

The two regimes share a backbone (a full-backing reserve, a notified white paper, no interest to holders, single-market passporting) but diverge on the points that matter most to a project planning an issuance. The table below summarises the core differences, each tied to its MiCA article.

These four rows are the decision points most projects weigh first. The full detail on each follows in the sections below, drawn from Title III and Title IV of the consolidated MiCA text.

Who can issue a stablecoin under MiCA?

Issuer eligibility is one of the strictest gates in the regime, and it differs sharply between the two token types. An EMT can be issued only by an existing regulated financial institution. An ART can be issued by a broader class of EU-established and authorised issuer. In both cases the issuer must be inside the EU and authorised before offering the token to the public.

Who may issue e-money tokens (EMT)

Art. 48 of MiCA restricts EMT issuance tightly. An EMT may be offered to the public or admitted to trading in the EU only by an issuer that is either a credit institution authorised under Directive 2013/36/EU or an authorised electronic money institution under Directive 2009/110/EC. The issuer must also have notified a crypto-asset white paper to its competent authority. There is no separate "stablecoin licence" for an EMT; eligibility flows from already being a bank or an e-money institution.

Who may issue asset-referenced tokens (ART)

Under Title III of MiCA, an ART issuer must be a legal person or other undertaking established in the EU and authorised by the competent authority of its home Member State, or be a credit institution. Authorisation covers governance, fit-and-proper assessment of management, and review of the reserve and own-funds arrangements. This is a dedicated authorisation route, unlike the EMT path which reuses existing banking or e-money licences.

Can a non-EU company issue a MiCA stablecoin?

No. Both regimes require the issuer to be established in the EU and authorised before offering the token to the public. A company incorporated outside the EU cannot directly issue a MiCA-compliant ART or EMT; it would need an EU-established, authorised entity to act as issuer. This requirement, set out across Title III and Title IV, is one of the main structuring questions a non-EU project must resolve early.

Reserve of assets and safeguarding requirements

Both ARTs and EMTs must be fully backed, but the legal mechanism differs. ART issuers maintain a segregated reserve of assets. EMT issuers safeguard funds under the e-money and payment-services regime. Neither may pay interest to holders. Together these rules ensure a stablecoin is always redeemable and behaves as a payment instrument rather than a deposit or an investment.

ART reserve of assets (Art. 36)

Art. 36 of MiCA requires an ART issuer to constitute and maintain a reserve of assets that is segregated from the issuer's own assets, that fully backs the liability to holders, and that is composed of low-risk and highly liquid assets. The reserve must be held with regulated custodians. The point of the reserve is that holders can always be made whole: the value backing the token sits ring-fenced from the issuer's commercial risk.

EMT safeguarding of funds (Art. 54)

For EMTs, Art. 54 of MiCA requires the funds received in exchange for the tokens to be safeguarded in line with the e-money and payment-services regime, and invested only in secure, low-risk assets denominated in the same currency as the token. This mirrors the protection already applied to electronic money. We deliberately do not assert any fixed percentage split of where the funds must sit; the often-repeated "30% with credit institutions" figure is not confirmed in the Art. 54 text reviewed and should not be stated without a primary source.

No interest to holders (Art. 50)

Art. 50 of MiCA prohibits issuers from granting interest to holders of EMTs, a rule mirrored for ARTs. The effect is that a MiCA stablecoin behaves as a payment token, not as a deposit or a yield-bearing instrument. Any "rewards" structure that functions as interest on the token holding is incompatible with the regime, a point projects frequently misjudge when they design token economics.

How much capital must a stablecoin issuer hold? (own funds)

Beyond the reserve that backs the token, an issuer must hold its own funds as a prudential buffer. This is one of the most concrete planning numbers in the regime, and it is often missing from generic stablecoin explainers. The figure scales with the size of the reserve, so a large issuance carries a materially larger capital requirement.

ART own funds (Art. 35)

Art. 35 of MiCA requires an ART issuer to hold own funds at all times equal to the highest of three measures: EUR 350,000; 2% of the average amount of the reserve of assets, averaged over the preceding six months and calculated at the end of each calendar day; or one quarter of the prior year's fixed overheads. For a small issuance the EUR 350,000 floor usually applies. For a large reserve the 2% figure dominates, so a sizeable stablecoin is a capital-intensive product.

EMT own funds via Art. 58

EMT issuers do not face the Art. 35 own-funds rule by default, but Art. 58 of MiCA applies the equivalent 2%-of-average-reserve requirement to significant EMTs and to EMTs denominated in a non-EU official currency. A heavily used or non-euro EMT is therefore pulled into the same capital regime as an ART. Where an issuer is classified as significant, the percentage may be raised by the supervisor, so the 2% base should be treated as a floor for significant issuers rather than a fixed cap.

Redemption rights: at par or at market value?

Redemption is where the ART and EMT regimes diverge most visibly, and where the old marketing content most often blurred the line. An EMT is redeemable at par. An ART is redeemable at the market value of its reserve. Both give the holder a permanent right to redeem, but the amount returned differs because the backing differs.

EMT redemption at par (Art. 49)

Art. 49 of MiCA gives EMT holders a claim against the issuer. EMTs are issued at par value and must be redeemable at any time and at par value, free of charge, in the official currency they reference. There is no discretion: a one-euro EMT is redeemable for one euro on demand. This par-value guarantee is what makes an EMT function as electronic money.

ART redemption at market value (Art. 39)

Art. 39 of MiCA gives ART holders a permanent right of redemption at any time, but the issuer redeems either by paying an amount equal to the market value of the referenced assets or by delivering the referenced assets, under a documented redemption policy. Because an ART references a basket, its redemption value moves with that basket. An ART is not guaranteed to redeem at par, which is the key practical difference from an EMT.

When does a stablecoin become "significant" under MiCA?

MiCA applies a tougher supervisory layer to the largest stablecoins. A token is classified as "significant" when it meets a threshold number of quantitative criteria, after which prudential supervision moves to the European Banking Authority. This is the rule that separates a national-scale stablecoin from a systemic one.

The significance thresholds (Art. 43 / Art. 56)

An ART or EMT is classified as significant when it meets at least three of the criteria in Art. 43(1) for ARTs and Art. 56(1) for EMTs. The confirmed quantitative thresholds, drawn from the consolidated text and the Delegated Regulation on significance criteria, are:

• More than 10 million holders.
• Value issued, market capitalisation or reserve of at least EUR 5,000,000,000.
• More than 2,500,000 transactions per day.
• More than EUR 500,000,000 in average aggregate transaction value per day.

Meeting at least three of these triggers significance. Additional qualitative criteria (gatekeeper status, importance for international payments, interconnectedness with the financial system) can also bear on the assessment.

Who supervises significant stablecoins? (EBA)

Once a stablecoin is classified as significant, supervisory responsibility transfers to the European Banking Authority, with the transition handled within 20 working days under the procedure. Non-significant ARTs remain supervised by the home-state national competent authority, with coordination from ESMA and the EBA. ESMA maintains the EU register and coordinates but is not the prudential supervisor of stablecoin issuers, a correction to the looser claim that "ARTs are supervised by ESMA." Significant ART issuers also face enhanced obligations under Art. 45, including remuneration policy, multi-custodian holdings and liquidity management for redemptions.

The non-euro stablecoin usage cap (the most distinctive MiCA rule)

The single most distinctive rule in the MiCA stablecoin regime is a cap on how widely a non-euro stablecoin may be used as a means of exchange inside the EU. It exists to protect EU monetary sovereignty, and it is the rule most generic explainers omit entirely.

How the means-of-exchange cap works

Art. 23 of MiCA provides that where an ART denominated in a currency that is not an official EU-area currency is used as a means of exchange and exceeds both 1,000,000 transactions per day and EUR 200,000,000 in average aggregate value of transactions per day, the issuer must stop issuing the token and submit a plan to the competent authority to bring usage back below the thresholds within 40 working days. Art. 58 applies the same restriction to EMTs denominated in a non-EU currency. The cap bites only when both limits are exceeded together.

What it means for USD-pegged stablecoins in the EU

In practice, the cap targets the most widely used dollar stablecoins. A USD-pegged EMT used heavily for everyday payments in the EU hits the same ceiling of 1,000,000 transactions per day and EUR 200,000,000 per day. Once both are exceeded, the issuer is forced to halt issuance and remediate within 40 working days. The rule does not ban USD stablecoins; it caps their use as a general means of exchange, while leaving their use for trading and investment largely untouched.

When MiCA stablecoin rules started applying (and passporting)

The stablecoin provisions came into force ahead of the rest of MiCA, and authorisation under either regime grants single-market access. Both points matter to an issuer planning a launch timeline and an EU-wide rollout.

Application dates

The ART and EMT provisions, Titles III and IV, began to apply on 30 June 2024, with the remainder of MiCA applying from 30 December 2024. These are the dates from which the stablecoin rules described on this page have legal effect. Issuers should confirm the exact date precision against the EUR-Lex text for any time-sensitive filing, as transitional arrangements can affect specific obligations.

Passporting and the white paper requirement

A MiCA authorisation grants single-market access: an authorised issuer can offer its token across the EU without re-authorising in each Member State. Both ART and EMT issuers also need a notified or approved crypto-asset white paper before offering the token to the public. The detail of the document is set out in our MiCA white paper rules, and the cross-border mechanics are covered in our explainer on how MiCA passporting works. For the full application sequence, see our MiCA transition timeline.

How Crypto Valley Partners AG helps stablecoin issuers

From our practice advising crypto and fintech projects out of Zug, the hardest part of a stablecoin engagement is rarely the headline figure. It is the structuring decision that comes before it: whether a token is an EMT or an ART, whether the issuer needs a bank, an e-money institution or a dedicated ART authorisation, and which Member State should host the authorisation that then passports across the EU.

Crypto Valley Partners AG works through that classification first, then maps the reserve, own-funds and redemption obligations onto the project's economics, and flags the significance thresholds and the non-euro cap before they become a problem at scale. Founders planning a stablecoin in the EU typically pair this MiCA analysis with a broader MiCA compliance checklist and, where the project has decided to proceed, with licensing for stablecoin issuers. For issuers choosing an EU base, our guide to CASP authorization in Germany and the broader MiCA regulation guide set out the surrounding framework. We do not publish a price list; every engagement is scoped to the token type and the chosen jurisdiction.
