Markets in Crypto-Assets Regulation (MiCA)

Authority

ESMA · National NCAs

Effective

June 30, 2024

Overview

The world's first comprehensive crypto-asset regulation

The big picture: MiCA creates a unified regulatory framework across all 27 EU member states plus the EEA — one rulebook, one passport.

How it works: Stablecoins fall into two categories:

  • EMTs (Electronic Money Tokens) — pegged to a single fiat currency, regulated as e-money
  • ARTs (Asset-Referenced Tokens) — backed by multiple assets, require separate authorization

Why it matters: Issuers need e-money or credit institution authorization, 1:1 reserve backing, segregated custody, and quarterly disclosure. Significant EMTs (daily transactions exceeding €200M or holders exceeding 10M) face enhanced requirements including higher capital buffers and ECB oversight.

Key Provisions

What MiCA requires for stablecoin issuers

01

EMT / ART Classification

The big picture: Classification determines the entire compliance regime.

  • Single-currency stablecoins (USDC, USDT) are EMTs — regulated as e-money
  • Multi-asset tokens are ARTs — require separate authorization

02

Authorization Requirement

What's required:

  • EMT issuers — must be authorized as e-money institutions or credit institutions in an EU member state
  • ART issuers — require specific CASP authorization

Why it matters: Passporting allows operation across all member states from a single authorization.

03

Reserve Requirements

The big picture: 1:1 backing with safe, low-risk assets.

  • Segregation — reserve assets must be separated from the issuer's own funds
  • Custody — held by authorized credit institutions
  • 30% minimum in bank deposits spread across multiple institutions

04

Significant Token Thresholds

The big picture: Tokens are classified as "significant" if they hit any of these thresholds:

  • €5B in issuance
  • 10M holders
  • €500M daily transaction value

Why it matters: Significant tokens face enhanced prudential requirements, including ECB involvement in supervision.

Compliance Impact

What changed when MiCA took effect

Tether (USDT)

What happened: Delisted from major EU exchanges for failing to obtain EMT authorization. Limited to grandfathered holdings.

Why it matters: USDT's dominance in emerging markets does not extend to regulated EU venues.

Circle (USDC)

What happened: Obtained e-money institution license in France via Société Générale partnership.

Why it matters: USDC is the first major stablecoin fully MiCA-compliant and available across all EU exchanges.

Exchanges

What happened: Binance, Kraken, and OKX restricted USDT trading pairs in the EU. Coinbase Europe positioned USDC as the default stablecoin.

What's next: New euro-denominated stablecoins (EURC, EURI) gaining share.
