MiCA Stablecoin Detail
How the EU's Markets in Crypto-Assets Regulation (MiCA) treats stablecoins — the ART and EMT categories, issuer requirements, reserve rules, and the practical effect on Tether, Circle, and other stablecoin issuers in Europe.
What MiCA Is
MiCA — the Markets in Crypto-Assets Regulation — is the European Union's comprehensive regulatory framework for crypto assets. It was adopted in 2023 and its main provisions came into force during 2024. Unlike US crypto regulation (which is scattered across the SEC, CFTC, and state agencies), MiCA is a single framework covering issuance, service provision, market abuse, and stablecoins. For stablecoins specifically, MiCA introduces two categories with distinct rules: Asset-Referenced Tokens (ART) and E-Money Tokens (EMT). Understanding this distinction is essential to understanding why Tether disappeared from many EU-based exchanges in 2024 while USDC continued to be widely available.
ART vs EMT — the Core Distinction
An **E-Money Token (EMT)** references a single fiat currency (e.g., 1 EMT = 1 EUR or 1 EMT = 1 USD). It's regulated similarly to electronic money — the issuer must be an authorised credit institution or e-money institution, reserves must be held in specific low-risk assets, and redemption rights must be guaranteed 1:1. An **Asset-Referenced Token (ART)** references multiple assets, a basket of currencies, or non-fiat assets like commodities. ARTs face heavier requirements: prospectus approval, ongoing capital requirements, and additional oversight when volumes exceed certain thresholds. USDT and USDC each fall under EMT once operating in the EU; multi-asset stablecoins would fall under ART.
The Practical Impact
Since MiCA's stablecoin provisions came into effect in mid-2024, EU-based exchanges have had to delist stablecoins whose issuers don't hold the required authorisation. Binance, Coinbase, Kraken EU, and others delisted or restricted USDT trading in the EU because Tether does not currently hold an EU EMT authorisation. Circle obtained an EMI license in France and issues USDC and EURC in compliance with MiCA, so those tokens remain fully tradeable. Users physically in the EU should assume that only MiCA-compliant stablecoins are available on regulated platforms; the rest may still be accessible via DEXs but not via licensed EU venues.
- MiCA is the EU's comprehensive crypto regulatory framework
- EMT = single-fiat stablecoin (regulated like e-money)
- ART = multi-asset or commodity-referenced token (heavier rules)
- EU exchanges have delisted non-compliant stablecoins, notably USDT for many users
Key Takeaways
- MiCA is the first comprehensive stablecoin regulation in a major jurisdiction
- The EMT vs ART distinction determines the specific rules that apply
- Circle's EMI license in France enables MiCA-compliant USDC and EURC
- Tether's lack of EU authorisation has led to USDT delistings on EU-regulated exchanges
