MiCA Implementation Timeline: Key Dates and Milestones

The Markets in Crypto-Assets Regulation did not enter force all at once. Its phased implementation — driven by the perceived urgency of stablecoin risk relative to the broader CASP landscape — created distinct compliance windows that vary by asset type, service category, and the member state in which a firm operates. For compliance officers, understanding exactly when each obligation applied, and to whom, is the necessary foundation for any MiCA gap analysis.

Legislative Milestones

MiCA’s legislative journey began with the European Commission’s proposal in September 2020. The trilogue negotiations between the Commission, Council, and Parliament concluded in June 2022. The Regulation was formally adopted by the European Parliament on April 20, 2023, and published in the Official Journal of the European Union on June 9, 2023 (OJ L 150). It entered into force 20 days after publication: June 29, 2023.

Entry into force, however, did not mean immediate application. MiCA’s substantive provisions applied in a phased schedule set by Article 149.

Phase 1: Stablecoin Provisions — June 30, 2024

Title III (Asset-Referenced Tokens) and Title IV (E-Money Tokens) became applicable on June 30, 2024 — exactly 12 months after the Regulation entered into force.

From this date:

• New issuers of ARTs must obtain authorization from their home NCA before offering tokens to the public in the EU
• New issuers of EMTs must be authorized as a credit institution or e-money institution under applicable EU law
• Existing ART issuers operating under pre-MiCA national frameworks must apply for MiCA authorization or wind down EU issuance
• Reserve asset requirements apply from this date for all authorized ART and EMT issuers
• The EBA’s supervisory role over significant stablecoin issuers becomes operative

ESMA published its first package of regulatory technical standards (RTS) under MiCA on June 30, 2024, covering the content of whitepapers for ARTs and EMTs, conflicts of interest disclosure for ART issuers, and the information required for authorization applications.

Phase 2: Full CASP Authorization — December 30, 2024

The full MiCA framework, including Title V (Crypto-Asset Service Providers), became applicable on December 30, 2024.

From this date:

• Any person providing crypto-asset services in the EU on a professional basis requires either CASP authorization under MiCA, or a valid transitional arrangement, or an existing authorization under a pre-MiCA national regime that a member state has recognized as equivalent for the transitional period
• Whitepaper requirements apply to new public offerings of crypto-assets other than ARTs and EMTs
• Market abuse prohibitions (Title VI) apply in full
• ESMA’s public CASP register becomes operative

Transitional Arrangements: Up to June 30, 2026

MiCA Article 143(3) gave member states the option to apply a transitional period of up to 18 months — meaning until June 30, 2026 — during which firms already registered under pre-MiCA national regimes may continue providing services without full MiCA authorization.

This transitional period is not automatic and is not uniform across member states. Critically:

Not all member states availed of the transitional period. Several NCAs, including France’s AMF and Germany’s BaFin, chose shorter transitional windows or required firms to apply for MiCA authorization immediately upon December 30, 2024.

Transitional arrangements apply only to existing registered firms. A new entrant setting up operations after December 30, 2024 cannot rely on transitional provisions. It must obtain full CASP authorization.

Transitional arrangements are service-scope-limited. A firm registered under a pre-MiCA national regime to provide exchange services cannot rely on that registration to provide custody services under the transitional arrangement if custody was not covered by its prior registration.

The June 30, 2026 deadline is absolute. There is no further extension. Firms that have not obtained CASP authorization by June 30, 2026 must cease EU operations if they are relying on transitional arrangements.

NCA Processing Timelines

The 40-working-day assessment window (extendable to 60) sets the formal maximum for NCA review. In practice, processing times vary significantly. Several NCAs with high application volumes — Lithuania’s Bank of Lithuania in particular — experienced backlogs in Q1 2025 as firms submitted applications ahead of the December 2024 deadline.

Firms targeting a June 30, 2026 deadline for transitional arrangements should plan for a submission no later than Q4 2025, allowing time for the NCA completeness review (25 working days), the 40-day assessment period, and any requests for additional information. Applications submitted in Q1 2026 risk not being determined before the transitional deadline.
