MiCA Phase 2 takes effect in November. Here’s what changes for the EU stablecoin market.
MiCA Title III and Title IV become fully applicable on 30 November 2026. We unpack the issuer caps, the EBA RTS, and what Circle, Tether and the RWA stablecoin issuers actually have to do.
On 30 November 2026, the second tranche of Regulation (EU) 2023/1114 — better known as MiCA — becomes fully applicable across the twenty-seven Member States. Title III, governing asset-referenced tokens (ARTs), and Title IV, governing e-money tokens (EMTs), have technically been in force since 30 June 2024, but the transitional regime under Article 143 expires this November. After that date, an issuer that wants to offer a euro- or dollar-denominated stablecoin to EU residents needs an authorisation from a competent national authority — BaFin in Frankfurt, the AMF in Paris, the CSSF in Luxembourg — or it needs to leave the market. The European Banking Authority published the final batch of Regulatory Technical Standards on reserve composition in July 2025, and the European Securities and Markets Authority closed the last of its Level 3 Q&A consultations in February 2026. The architecture is finally complete.
What is at stake is roughly $165 billion of stablecoin market capitalisation, of which the EBA estimates somewhere between $18 and $24 billion is held by EU-resident wallets. That is the addressable market the regulation is trying to bring on-balance-sheet. Two issuers — Circle, which obtained an EMI licence in France in July 2024, and Société Générale-FORGE, which has issued EURCV since 2023 — already operate inside the perimeter. Tether does not, and has been openly hostile to MiCA’s reserve rules. The interesting question for the next ninety days is not whether USDT gets delisted from Binance EEA and Kraken — it largely already has — but whether the secondary issuers (Agora, Ripple’s RLUSD, Ethena’s USDe, BlackRock’s BUIDL feeder shares) choose Paris, Frankfurt, or Dublin, and what each regulator is willing to wave through.
What actually changes on 30 November
The legal mechanism is unglamorous. Article 48 of MiCA prohibits the offering or admission to trading of an EMT by anyone other than a credit institution or an authorised electronic money institution. Article 16 does the same for ARTs. The transitional regime in Article 143(3) gave issuers operating before 30 June 2024 an eighteen-month grandfathering window — that window closes on 30 November 2026. From 1 December onward, a crypto-asset service provider (CASP) authorised under Title V cannot list a stablecoin whose issuer lacks the corresponding Title III or Title IV authorisation. In practice that means the order book disappears, not that any user holding the token is forced to sell. Self-custody remains untouched; the regulation is an issuer- and venue-level instrument, not a wallet-level one.
The reserve rules are where the engineering shows. Article 36 requires EMT issuers to hold reserves of at least equal value, segregated from the issuer’s own funds, and — this is the bite — at least 30% of those reserves must sit in deposits with credit institutions for non-significant EMTs, rising to 60% for significant ones (Article 45 read with the EBA RTS on own funds and liquidity finalised in early 2025). The rest can sit in highly liquid financial instruments with minimal market and credit risk. There is a daily redemption-at-par obligation under Article 49, and no interest may accrue to holders. That last point — no yield — is the provision that pushed BUIDL and other tokenised T-bill funds toward the ART regime rather than the EMT regime, with all the disclosure and white paper requirements that come with Title III.
The “significant” threshold and why €200m matters
Article 43 and Article 56 introduce a two-tier regime. A stablecoin is “significant” if it meets three of seven criteria, but in practice two thresholds dominate the conversation: a customer base above 10 million holders, and an average daily volume of transactions used as a means of exchange above €500 million, or an average daily number of transactions above 2.5 million. The EBA’s Implementing Technical Standards further specify that the relevant volume threshold for triggering reinforced supervisory scrutiny — including direct EBA oversight under Article 117 — kicks in at an average daily transaction volume of €200 million across all EU Member States combined, measured on a rolling 90-day basis.
Once a token crosses that threshold, the issuer faces additional own funds requirements (3% of the average amount of the reserve assets, against 2% for non-significant), interoperability obligations, and a recovery and redemption plan reviewed annually by the EBA Joint Supervisory Team. For non-EUR-denominated EMTs, Article 58 — the most controversial provision in the whole regulation — caps the number of transactions used as a means of exchange within the EU at 1 million per day and the aggregate value at €200 million per day. Above those caps, the issuer must stop issuing new tokens until volumes fall back below the threshold. That is the article the US Treasury, in its October 2024 comment letter, called “unprecedented in international financial regulation.”
Issuer-by-issuer: who is ready, who is not
| Issuer | Token | MiCA status (as of Nov 2026) | Likely Art. 58 impact |
|---|---|---|---|
| Circle | USDC / EURC | EMI licence, ACPR (France), July 2024 | USDC volumes near €200m/day cap; EURC unaffected |
| Tether | USDT / EURT | No authorisation sought; delisted from EU CASPs | Out of scope by exit, not compliance |
| Société Générale-FORGE | EURCV | Credit institution, authorised pre-MiCA | Below significance thresholds |
| Paxos / Agora | USDG / AUSD | Authorisation pending, MFSA (Malta) route | Volumes well below cap |
| Ripple | RLUSD | EMI application filed Q1 2026, Ireland | Below cap; growth-constrained by design |
| BlackRock / Securitize | BUIDL | Treated as MiFID II fund unit, not EMT | Out of MiCA stablecoin perimeter |
| Ethena | USDe | No EU authorisation; not a stablecoin under Art. 3(7) | May be treated as ART or other crypto-asset |
Circle is the only major dollar-stablecoin issuer that played the regulation as written. Its EMI authorisation from the Autorité de Contrôle Prudentiel et de Résolution covers both USDC and EURC, and gives it passporting rights into every Member State. The trade-off is the Article 58 cap. USDC’s measured EU on-chain volume — what the EBA’s monitoring methodology counts as “used as a means of exchange” rather than as collateral or as a trading pair — sits around €140–180 million per day depending on the week. The market has been watching that number creep upward all year. The first issuer-imposed mint pause under Article 58, when it comes, will be a real-world test of whether the cap can hold a credible peg or whether it generates an arbitrage premium of the kind we used to see in the offshore renminbi market.
What the EBA Q&As actually say
The interesting Level 3 guidance landed quietly. The EBA’s single rulebook Q&A 2025_7341 clarified that algorithmic stabilisation mechanisms — the category that killed UST in May 2022 — fall outside the EMT definition entirely and are prohibited from being marketed as stablecoins under Article 19(2)(b). That formalises what ESMA had been signalling since the FTX collapse: there is no path to authorisation for a Terra-style design in the Union, full stop. Separately, Q&A 2025_7402 confirmed that wrapped tokens (wBTC, wETH) are not in themselves EMTs because they do not aim to maintain a stable value by reference to an official currency, which removes one source of legal uncertainty for CASPs running cross-chain bridges.
The Q&A that matters most for the next six months is 2026_7588, which clarifies how the Article 58 transaction count is measured for tokens used in DeFi. The EBA’s view — and it is a view, not a clear textual reading — is that swaps within an automated market maker pool count toward the cap if the EU-resident user can be identified through the CASP onramp, but contract-to-contract transfers between two non-custodial addresses do not. In practice that means Uniswap volumes on Arbitrum and Base are partially in scope, depending on how the front-end attributes the user. Expect litigation. For traders, the practical effect is that any EU-facing CASP will start filtering and reporting volume the moment the running 90-day average hits €160 million, which is the EBA’s informal early-warning level.
How this diverges from the US approach
The US payment stablecoin framework that emerged from the GENIUS Act (P.L. 119-12, signed July 2025) takes a structurally different route. Federal qualified payment stablecoin issuers can choose between a national bank charter from the OCC, a state trust charter recognised under the federal preemption provisions, or — for issuers under $10 billion in outstanding tokens — a state-only regime supervised by the relevant state banking regulator. There is no equivalent of Article 58. There is no volume cap on non-USD-denominated stablecoins. The reserve composition rules are stricter on paper — only cash, insured deposits, T-bills under 93 days, and overnight repos — but the supervisory architecture is single-jurisdiction federal-or-state rather than the dual EBA/national competent authority model in the Union.
The result, twelve months from now, will be a bifurcated global market. A US-chartered Circle, Paxos or Anchorage stablecoin will be freely usable as a means of exchange in any US jurisdiction, with single-regulator supervision and no volume caps. The same token, offered into the Union, will be subject to the €200m/day brake — unless it is denominated in euro. That is not an accident; the Article 58 mechanism was explicitly designed to protect monetary sovereignty by limiting the substitution of foreign-currency stablecoins for euro deposits. Whether it succeeds depends on whether euro-denominated EMTs reach the liquidity threshold needed to be a credible alternative. As of November 2026, the answer is “not yet.” EURC and EURCV combined sit below €500 million in circulation. The market the regulator wants to exist is the market the regulator now needs to wait for.
Three practical consequences for the next ninety days
- Order-book reshuffling on EU CASPs. Expect Binance EEA, Kraken EU, and Coinbase Germany to publish updated supported-asset lists in the first week of November. Tokens without an authorised issuer disappear from spot pairs first, then from custody.
- USDC’s first taste of Article 58. If on-chain volume continues at the current trajectory, Circle will be forced to either pause EU minting or accept an EU-issued sub-balance with separate accounting. The technical solution is already drafted; the political question is whether ACPR is willing to be the regulator that imposed the first mint freeze.
- RWA stablecoins routed away from MiCA. BUIDL and similar tokenised money market funds are being structured as MiFID II fund units rather than EMTs, which gives them yield-bearing status that EMTs cannot have. That is a regulatory arbitrage the Commission is aware of and may close in the MiCA review under Article 140 due in 2027.
For our readers monitoring depeg risk and on-chain liquidity, the relevant pages are the stablecoin peg monitor, the market dashboard, and the regulatory calendar, which now lists every Member State authorisation date through 2027. The full text of the regulation, including the consolidated version incorporating the 2024 corrigenda, sits on EUR-Lex. The EBA’s RTS and ITS are at eba.europa.eu. Read the actual articles. The secondary commentary, including most of what circulated on crypto Twitter last week, is wrong in interesting ways.
