The EU Regulated Stablecoins First
MiCA's stablecoin provisions (Titles III and IV) became applicable on 30 June 2024 — six months before the broader CASP regime — reflecting how seriously the EU took stablecoin risk after earlier market failures. The result is the world's first stablecoin rulebook, and it sets a template other jurisdictions are following.
For issuers and exchanges, the message is simple: in the EU, a stablecoin is a regulated financial product, not a free-floating crypto-asset.
Every Stablecoin Is an EMT or an ART
MiCA does not have a category called "stablecoin." Instead, every stablecoin falls into one of two regulated buckets:
- E-money token (EMT): references a single official currency — a euro or dollar stablecoin. Governed by Title IV. See our EMT guide.
- Asset-referenced token (ART): references a basket, commodity, or mix of assets. Governed by Title III. See our ART guide.
Single-currency fiat stablecoins — the vast majority of the market — are EMTs, and EMTs can only be issued by credit institutions or electronic money institutions.
The Core Rules for Compliant Stablecoins
Across both categories, MiCA requires:
- Full reserve backing — 1:1 for EMTs; a reserve of assets for ARTs — segregated and held with qualified custodians;
- Redemption rights — at par and on demand for EMTs;
- Authorized issuers — credit institution / EMI for EMTs; authorized issuer for ARTs;
- A compliant, regulator-engaged white paper;
- No interest paid to holders;
- Transparency and audit of reserves.
These rules exist to guarantee that a stablecoin can always be redeemed for what it claims to be worth.
Why Exchanges Delisted Some Stablecoins
As MiCA's stablecoin rules took effect, EU exchanges restricted or delisted stablecoins whose issuers were not authorized under MiCA — because offering a non-compliant EMT to EU users is itself a breach. Some major dollar stablecoins were affected where their issuers had not (yet) obtained EU authorization, while euro and dollar tokens from MiCA-authorized issuers remained available.
For a crypto exchange, listing eligibility is now a compliance question: you can only offer stablecoins from issuers that meet MiCA's requirements. That makes issuer authorization a commercial gatekeeper to the EU market.
The Non-Euro Transaction Caps
To protect the euro's role, MiCA limits how widely non-euro stablecoins can be used as a means of exchange in the EU. Where a non-euro EMT or ART used as a means of exchange exceeds roughly 1 million transactions and €200 million per day within a currency area, the issuer must stop issuing until usage falls back. Euro-denominated stablecoins are not subject to this cap.
This is a structural advantage for euro stablecoins in the EU and a key planning factor for any dollar-pegged project, as we explain in the EMT guide.
What Stablecoin Issuers Must Do
To bring a compliant stablecoin to the EU market, an issuer must: classify the token (EMT vs ART), obtain the right authorization (EMI for an EMT; ART authorization otherwise), design and custody a compliant reserve, build the redemption mechanism, publish a compliant white paper, and plan for the significant-token regime if scale is the goal.
