MiCA

DEFINITION

Markets in Crypto-Assets — the European Union's harmonized rulebook for crypto-asset issuers and service providers. It replaces 27 separate national regimes with one licensing framework valid across the whole EU.

Before MiCA, an exchange licensed in Germany had no automatic right to serve customers in France or Italy — each country ran its own registration regime. MiCA replaces that patchwork with a single "CASP" (Crypto-Asset Service Provider) authorization: get licensed in one EU member state and passport that license across all 27, the same logic the EU already uses for banking and investment licenses.

The regulation is split into two tracks. Stablecoin rules — covering e-money tokens and asset-referenced tokens — took effect first, in June 2024. The broader CASP licensing regime, covering exchanges, custodians, and brokers, applied from December 30, 2024. Firms operating under national "grandfathering" transition rules had until mid-2025 in most member states to come into full compliance.

Crucially, MiCA regulates issuers and intermediaries — not decentralized, issuerless assets. Bitcoin has no issuer to license, so it sits outside MiCA's token-issuance disclosure rules the way a stablecoin or exchange-listed token doesn't. But any exchange, broker, or custodian serving EU retail customers — including Kraken, Binance, and Coinbase's EU entities — needs CASP authorization regardless of what assets it lists.

IN A SENTENCE

"MiCA doesn't touch bitcoin itself — it licenses the exchanges and custodians that hold it for you."
