ART or EMT? How MiCA Sorts a Stablecoin, and Why the Label Matters

Two boxes, one test

MiCA does not regulate “stablecoins” as a single product. It divides them into e-money tokens and asset-referenced tokens, and the division is made by a single question: what does the token reference?

The Latvijas Banka classification guidance states the test in two short definitions.

An asset-referenced token is a type of crypto-asset that aims to maintain a stable value by referencing another value or right, or a combination of them, including one or more official currencies. It can be referenced to another asset, one or more official currencies, other crypto-assets or a combination; it can be redeemed at market value; and it cannot be subject to interest payments.

An e-money token is a type of crypto-asset that purports to maintain a stable value by referencing the value of one official currency. Its issuers can only be credit institutions or e-money institutions; it cannot be subject to interest payments; and all EMTs are considered e-money under the Electronic Money Directive, though not all e-money is an EMT.

The ART definition in the regulation itself is drafted as a residual category: an ART is a crypto-asset that is not an EMT and that references another value or right. That ordering matters. A token that references a single official currency is an EMT first; it does not become an ART because its issuer would prefer the ART rulebook.

Why the issuer restriction is the real difference

The reference test sounds technical. The consequence is institutional.

An EMT can only be issued by a credit institution or an e-money institution. That is a narrower set than “any firm with a MiCA authorisation”, and it is the reason a dollar-pegged token is not simply a product decision. The issuer has to be a bank or an electronic money institution, which brings its own capital, safeguarding and supervisory obligations.

An ART issuer is not confined to those two institution types, but it needs the relevant authorisation under MiCA. The EBA’s page on ARTs and EMTs states the requirement directly: issuers of asset-referenced tokens and electronic money tokens are required to hold the relevant authorisation to carry out activities in the EU, and the requirements are set out in MiCA and complemented by the EBA’s technical standards and guidelines.

The supervisory consequence follows the label. An EMT is, by definition, e-money, so the regime that already governs electronic money applies in addition to MiCA. An ART is a newer object, and the EBA has built out a body of standards for it: regulatory technical standards on the highly liquid financial instruments eligible for the reserve of assets, guidelines on liquidity stress testing, guidelines on recovery plans and guidelines on redemption plans. The existence of those documents is a useful signal of what supervisors expect an ART issuer to be able to demonstrate.

Reserves are not a single rule

Both categories require backing, but the legal form differs, and a reader comparing two stablecoins should not assume that “backed 1:1” means the same thing in both boxes.

For an ART, the EBA’s standards speak of a reserve of assets, with technical standards defining which financial instruments count as highly liquid enough to be held in it. The same body of work includes liquidity stress testing and redemption planning, which are about what happens when the reserve has to be converted quickly rather than about what it holds on a calm day.

For an EMT, the token is e-money, and the prudential framework for e-money institutions applies. That framework is about safeguarding funds received in exchange for the e-money, not about assembling a portfolio of eligible assets. The two regimes can produce similar-looking balance sheets and very different legal claims on them.

This is why a reserve report alone does not settle the safety question. The report says what is held; the regime says who has a claim on it and what happens if the issuer fails. Our guide to what a reserve attestation does and does not prove covers the limits of the document itself, and stablecoin reserve composition covers what the assets inside it mean for liquidity.

Significance is a second label, and it is earned

MiCA adds a category on top of the two: the significant ART or EMT. The EBA makes the determination, and the Latvijas Banka guidance lists the criteria. At least three must be met:

• more than 10 million holders of the token;
• a value of the token issued, market capitalisation or size of the reserve above EUR 5 billion;
• an average of more than 2.5 million transactions per day and more than EUR 500 million in average aggregate daily value;
• the significance of the issuer’s activities on an international scale, including use for payments and remittances;
• the issuer is a provider of core platform services;
• the interconnectedness of the token or its issuers with the financial system.

The numeric thresholds are easy to quote and easy to misread. They are a conjunction, not a checklist of alternatives: a token with 11 million holders but a EUR 1 billion reserve does not qualify on two criteria alone. The qualitative criteria are deliberately open, and the EBA, not the issuer, decides.

Significance changes the supervisory intensity rather than the definition. A significant token is still an ART or an EMT; it is one that has crossed a threshold into a heavier regime.

What the label does not decide

Three things that users often assume follow from the label do not.

It does not decide whether the token is safe. An EMT issued by a credit institution and an ART issued by a well-capitalised specialist can both fail to redeem at the expected value. The label tells you which rulebook applies and which institution may issue; it does not tell you how much risk the reserve carries.

It does not decide whether the token is redeemable by you. MiCA governs the issuer’s obligations and the offering in the EU. Whether a particular holder can redeem, on which chain, with which minimum, and at what cost is a matter of the issuer’s terms and the distribution channel. Our guide to stablecoin redemption and network compatibility covers the operational side.

It does not decide the tax or accounting treatment. A token classified as an EMT for MiCA purposes can still be a different kind of asset for tax, and the classification does not change what a broker reports.

How to read a stablecoin’s MiCA status

A practical checklist, in the order the questions become answerable:

1. Read the reference. One official currency or a basket? The answer puts the token in one box before any marketing claim is considered.
2. Identify the issuer and its licence. For an EMT, the issuer should be a credit institution or an e-money institution. For an ART, the issuer should hold the relevant MiCA authorisation.
3. Check the register. The ESMA interim MiCA register publishes white papers and lists of authorised ART and EMT issuers, and it is the primary source for whether a claim of authorisation is current.
4. Read the reserve standard, not just the reserve. An ART’s reserve is governed by eligible-asset and liquidity rules; an EMT’s backing is governed by e-money safeguarding. The two are not interchangeable.
5. Check the significance label. If the issuer describes the token as significant, the EBA’s determination is the source, not the issuer’s own description.
6. Separate the token from the venue. Holding an EMT on an exchange is a claim on the exchange, not a direct claim on the issuer. The distinction is the same one that separates money market funds from stablecoins: similar stability, different legal claim.

The comparison between the two largest dollar tokens is a useful test of the framework. USDT and USDC: how the two differ is about issuers and reserves; MiCA adds a third question — which box each one occupies in the EU, and which institution is allowed to stand behind it.

Risk note. The definitions, issuer restrictions, authorisation requirement, reserve standards and significance criteria in this article were read from Latvijas Banka’s MiCA classification guidance, the EBA’s ART and EMT page and ESMA’s MiCA page on 2026-11-02. MiCA is being implemented in stages and national competent authorities apply it; the text of Regulation (EU) 2023/1114 remains the authoritative source. Nothing here is legal or investment advice.
