The EU MiCA framework, Regulation (EU) 2023/1114, governs stablecoins in 2026 under two classes: e-money tokens (EMTs), pegged to a single fiat currency, and asset-referenced tokens (ARTs), backed by a basket. ESMA technical standards are live, setting reserve segregation, custody, white paper, and redemption-at-par rules. EMT issuers must be authorized credit institutions or EMIs; ARTs face stricter capital and governance duties. Reserves must be bankruptcy-remote and held with qualifying custodians.
​

The EU's Markets in Crypto-Assets Regulation (MiCA) entered full effect on 30 December 2024, with the stablecoin rules under Titles III and IV applying earlier from 30 June 2024. By April 2026, MiCA has produced a tiered authorization regime, prudential thresholds for non-euro tokens, and the first wave of enforcement actions against non-compliant issuers. This article summarizes the current state of MiCA stablecoin regulation: how the regulation distinguishes asset-referenced tokens (ARTs) from e-money tokens (EMTs), what reserve composition issuers must hold, where the transaction caps bite, and which enforcement decisions have shaped the regime so far.
​

MiCA scope: ART vs EMT
​

MiCA splits stablecoins into two regulated categories. Asset-referenced tokens (ARTs), governed by Title III of Regulation (EU) 2023/1114, reference any value, right, or basket , multiple fiat currencies, commodities, crypto-assets, or a combination. E-money tokens (EMTs), governed by Title IV, reference the value of one official currency. A single-fiat USD-pegged token like USDC or USDT falls under EMT rules. A basket-pegged token or commodity-backed token falls under ART rules.
​

The classification matters because the two regimes carry different obligations. EMT issuers must be authorized as either a credit institution or an electronic money institution under Directive 2009/110/EC, and they face the strictest reserve and redemption rules. ART issuers must obtain a separate ART authorization from their home-state competent authority. The European Banking Authority (EBA) oversees significant ARTs and significant EMTs (where issuance crosses thresholds tied to user base or transaction volume), while smaller issuers stay under national supervision.
​

A third category sits outside MiCA entirely: tokens that meet the definition of a financial instrument under MiFID II, or tokens issued by central banks. The ESMA published a final report on classification guidelines in December 2024 clarifying when a tokenized instrument crosses the line into MiFID territory. Algorithmic stablecoins that do not maintain stable value through reserves are explicitly carved out of the EMT category and may instead be treated as crypto-assets under MiCA's general regime, or banned outright depending on design.
​

Issuer authorization requirements
​

To issue an EMT in the EU, an entity must be authorized as a credit institution under CRR (Regulation 575/2013) or as an electronic money institution under Directive 2009/110/EC. The applicant submits a crypto-asset white paper to the home-state national competent authority at least 40 working days before issuance. The white paper requirements are codified in Article 51 of MiCA, with content templates in Commission Delegated Regulations published through 2024 and 2025.
​

ART issuers face a heavier authorization burden. Article 18 of MiCA requires an applicant to submit a programme of operations, governance arrangements, a description of the reserve of assets, complaints-handling procedures, business continuity plans, internal control mechanisms, and a recovery plan. The competent authority has 60 working days to assess completeness, then 25 working days to consult the EBA and ESMA, and then a decision window. EBA published final guidelines on recovery plans for issuers in November 2024, setting expectations for triggers, indicators, and recovery options.
​

Capital requirements scale with issuance. Article 35 of MiCA imposes own funds of at least EUR 350,000, or 2% of the average amount of the reserve of assets, whichever is higher. Significant ARTs and EMTs face an enhanced 3% own-funds requirement. The threshold for a "significant" classification is set in Article 43: more than 10 million holders, issuance value above EUR 5 billion, more than 2.5 million transactions per day, or daily transaction value above EUR 500 million, among others. Once triggered, supervision shifts from the national competent authority to the EBA.
​

Third-country issuers cannot offer ARTs or EMTs to EU residents without going through this authorization process or partnering with an EU-authorized entity. Tether's USDT was delisted from several EU venues in late 2024 because Tether had not obtained EU EMT authorization. Circle obtained French EMI authorization in July 2024, allowing EURC and USDC to remain available across the EEA.
​

Reserve composition under MiCA
​

Both ARTs and EMTs must be backed by a reserve of assets that is segregated from the issuer's own assets and held in custody with a credit institution or qualifying custodian. The reserve must equal or exceed the value of tokens in circulation at all times, and the issuer must publish a monthly attestation of the reserve composition.
​

EMT reserves face a tight composition rule. Under Article 54 of MiCA, at least 30% of the reserve for non-significant EMTs and 60% for significant EMTs must be held as deposits in commercial banks. The remainder may be held in highly liquid financial instruments with minimal market and credit risk, as defined in Commission Delegated Regulation (EU) 2024/2730. The EBA's regulatory technical standards on prudential requirements further specify concentration limits , no more than 25% of the cash reserve may sit with a single credit institution for non-significant tokens, dropping to 10% for significant tokens.
​

ART reserves can hold a wider range of assets, but with proportional risk controls. Reserve assets must be invested only in highly liquid financial instruments, with maturities and credit quality matched to redemption obligations. Article 38 mandates daily reconciliation between the reserve and outstanding token supply, and at least one independent audit per year. Where the underlying basket includes commodities or other crypto-assets, additional valuation and custody rules apply under Commission Delegated Regulation (EU) 2024/2820.
​

The redemption right is unconditional and at par. Article 49 (EMTs) and Article 39 (ARTs) require the issuer to honor redemption requests at face value, with no fees that exceed the cost of execution. This is a notable departure from earlier stablecoin practice where fees on bulk redemption were common. It also creates a structural difference from non-EU stablecoins where redemption is gated by minimums or KYC tiers.
​

Transaction caps for non-euro stablecoins
​

Article 23 (ARTs) and Article 58 (EMTs) impose what the regulation calls "monitoring measures" on stablecoins denominated in a non-EU currency once usage crosses defined thresholds. The cap is the most-discussed feature of MiCA among dollar-stablecoin issuers because it directly limits how much USD-pegged volume can flow through EU rails.
​

The thresholds, set out in MiCA and clarified in EBA regulatory technical standards on methodology for estimating quarterly average number and aggregate value, kick in when an EMT is used as a means of exchange for goods and services within a single quarter at:

Once breached, the issuer must stop issuing the EMT until usage drops below the threshold, and the competent authority may impose corrective measures. The cap applies only to use in payment for goods and services , not to use in trading, custody, or onchain settlement between counterparties. The distinction between "means of exchange for goods and services" and other use cases is defined in EBA's final RTS on EMT thresholds published in 2024.
​

For dollar stablecoins entering EU payments, the practical effect is that growth in EU consumer payment volume is bounded. Wholesale crypto trading, treasury settlement, and B2B onchain transfers fall outside the cap. As of Q1 2026, no dollar-pegged EMT has publicly reported breach of the threshold, but the methodology requires quarterly self-reporting and any false reporting carries administrative penalties under Article 111.
​

Disclosure and white paper requirements
​

MiCA requires every issuer to publish a crypto-asset white paper before offering tokens to the public or seeking listing on a trading platform. The white paper is the central disclosure document. Required content is set out in Articles 19 (ARTs) and 51 (EMTs), with structure and templates in Commission Delegated Regulation (EU) 2025/305.
​

White paper sections include: the issuer and any group structure; the type of crypto-asset and rights attached; the underlying technology including consensus mechanism and incentive structure; risks specific to the token, the issuer, and the project; environmental impact, broken out by per-transaction energy use and total annual consumption; and the governance arrangement of the reserve. The environmental disclosure rules , specified by ESMA's RTS on sustainability indicators finalized in March 2025 , require disclosure of energy mix, renewables share, and carbon footprint methodology.
​

Material changes after publication trigger a duty to notify holders and the competent authority within 30 days, and to publish an updated white paper. There is no equivalent of the SEC's Form 8-K material-event filing, but the duty operates comparably for token-related events: change of custodian, change of reserve composition exceeding defined deltas, change in issuance pace, or any event affecting redemption capacity.
​

The white paper is not pre-approved by the competent authority. The authority has the right to suspend or prohibit an offer where the white paper does not meet requirements, but the default model is notification, not approval. ART white papers, by contrast, must be approved before publication under Article 17. EBA released a 2025 guidelines update on what constitutes a complete ART authorization application, addressing recurring gaps in early submissions.
​

Cross-border passporting
​

An issuer authorized in one EU member state may offer the token across the EEA under MiCA's passporting regime. The home-state authority notifies host-state authorities, and the host has the right to request additional information but cannot block the offer absent breach. The mechanic mirrors banking and MiFID II passporting and is set out in Article 21 (ARTs) and Article 50 (EMTs).
​

Passporting in practice has concentrated authorizations in a small number of member states. France (AMF and ACPR), Germany (BaFin), Ireland (Central Bank of Ireland), the Netherlands (DNB), Luxembourg (CSSF), and Malta (MFSA) have processed the bulk of public ART and EMT authorizations through Q1 2026. Circle's EMI authorization sits in France; Société Générale-Forge's EUR CoinVertible holds a French authorization too. The ESMA register of published white papers lists every notified ART and EMT, with links to the underlying documents.
​

Crypto-asset service providers (CASPs) authorized under Title V of MiCA can also passport. A CASP authorized in Lithuania can offer custody, exchange, or transfer services across all 27 member states without seeking separate authorizations. The first wave of CASP authorizations in 2025 included Coinbase Germany, Bitpanda, and Kraken Ireland. Existing service providers benefit from a transitional regime under Article 143, allowing them to continue operating until 1 July 2026 (or earlier if a member state shortens the window) while their full MiCA authorization is processed.
​

Routing stablecoin payments across EU member states does not, on its own, trigger any per-state authorization. Once the EMT issuer is authorized and passported, the token moves freely. Where a payment institution or CASP is in the loop, that intermediary needs its own passport. Cross-border execution networks, including Eco Routes, treat the EMT as the unit of value moving onchain , the regulatory perimeter sits with the issuer and any CASP intermediary, not with the routing layer itself.
​

Enforcement update (2025-2026)
​

The first 18 months of MiCA enforcement have produced a mix of delistings, withdrawn authorizations, and a small number of administrative fines. The pattern is more disciplinary than punitive , authorities have leaned on suspension and remediation orders rather than headline penalties.
​

Tether's exclusion from compliant EU venues remains the most visible event. From late 2024 through Q1 2025, major exchanges including Coinbase, Crypto.com (in some jurisdictions), and Bitstamp delisted USDT for EU residents because Tether did not pursue EMT authorization. Tether's stated reason, summarized in CEO Paolo Ardoino's July 2024 Reuters interview, was that the reserve composition rule (60% bank deposits for significant EMTs) was incompatible with Tether's existing reserve mix.
​

BaFin issued the EU's first MiCA-related cease-and-desist against a smaller stablecoin issuer in March 2025, suspending issuance on the grounds that the white paper omitted reserve attestations. The issuer remediated within 90 days and resumed issuance.
​

Verify the specific EU compliant-stablecoin float figure against the ESMA TRV report cited; replace with the exact number from the source. Verify against the ESMA TRV Q1 2026 publication; replace with the exact figure cited in that report.
​

For dollar-stablecoin issuers entering EU rails, the operational reality is that compliance is a precondition, not an option. For EUR-stablecoin builders, MiCA has produced a relatively rare outcome: clear rules, a workable authorization process, and a passport that scales offerings across 27 markets. The next phase of enforcement, expected through 2026 and 2027, will test the transaction cap once a major dollar-stablecoin approaches the daily threshold and the suite of significant-EMT supervisory tools that flow from that.
​

Frequently asked questions
​

MiCA does not ban USDT. It requires any EMT offered to EU residents to be issued by an authorized credit institution or electronic money institution. Tether has not pursued EU EMT authorization, so EU-regulated venues have delisted USDT for EU users. USDT remains legal to hold and transact peer-to-peer onchain.
​

An EMT references one official currency (USD, EUR, GBP). An ART references any other value or basket , multiple currencies, commodities, crypto-assets, or combinations. EMTs follow Title IV of MiCA and are issued by credit institutions or EMIs. ARTs follow Title III and require separate authorization. EMT rules are stricter on reserves; ART rules are stricter on authorization scope.
​

For non-euro EMTs used as a means of exchange for goods and services, MiCA imposes a cap of 1 million transactions per day or EUR 200 million in aggregate daily value. Once breached, the issuer must halt new issuance until usage drops below the threshold. The cap does not apply to trading, custody, or onchain B2B settlement.
​

Yes, if the issuer establishes an EU subsidiary with credit institution or EMI authorization, or partners with an EU-authorized entity. Circle obtained French EMI authorization in July 2024 and operates USDC and EURC across the EEA. Direct cross-border issuance from a US entity to EU residents without EU authorization is not permitted.
​

An EMT issuer must hold reserves equal to the value of tokens in circulation, with at least 30% in commercial bank deposits for non-significant EMTs and 60% for significant EMTs. The remainder must sit in highly liquid financial instruments. Reserves are segregated, audited, and reconciled daily, with monthly public attestations.
​

The ESMA register of published crypto-asset white papers lists every notified ART and EMT with links to the white papers and the issuing entity. Each EU national competent authority also maintains a register of authorized credit institutions, EMIs, and CASPs. Authorization details , including any conditions or restrictions , are public.
