The EU has implemented MiCA as a fully operational, passportable crypto licensing regime. The UK, by contrast, is constructing a phased, FCA-driven framework under traditional financial services law. For crypto providers, merchants, and regulators, understanding these structural differences is essential for cross-border strategy, licensing, and risk management.

Key Findings

• The EU’s MiCA regime is fully applicable and introduces a harmonized CASP license with passporting across Member States.
• The UK does not have MiCA; it operates an AML registration regime while building a broader authorization framework under FSMA.
• MiCA authorization is mandatory now in the EU; full UK authorization for core crypto activities is expected to apply from 2027.
• The UK framework is likely broader in scope (including lending and certain DeFi intermediation).
• MiCA includes dedicated token issuance rules (ARTs/EMTs); the UK regulates stablecoins under payment and systemic frameworks.
• Cross-border providers must pursue separate authorization tracks in the EU and the UK.
• Market-abuse and consumer protection regimes differ in structure but converge in intensity.

1. The EU Framework: MiCA as a Unified Licensing Regime

MiCA (Markets in Crypto-Assets Regulation) establishes a comprehensive regulatory framework across the EU.

Licensing Path (EU – MiCA)

Who must be licensed?
Crypto-Asset Service Providers (CASPs), including:

• Exchanges (trading platforms)
• Custodians
• Brokers
• Portfolio managers
• Transfer services
• Placement services

Authorization Process:

• Application to national competent authority (e.g., BaFin, AMF, Bank of Lithuania).
• Assessment of governance, capital, AML systems, IT resilience.
• Once approved → EU passporting rights.

Capital Requirements:

• Tiered own-funds requirements depending on service type.
• Ongoing prudential monitoring.

Timeline:

• Transitional regimes expired or are expiring across Member States.
• Grandfathering windows (e.g., Lithuania end-2025) have closed.
• By 2026, full MiCA compliance will be the norm across the EU.

Reporting & Consumer Protection (EU)

• Whitepaper requirements for token issuance.
• Strict marketing disclosure obligations.
• Complaint handling mechanisms.
• Segregation of client assets.
• Prudential reporting to national authorities.
• ESG disclosure obligations for certain tokens.

Market Abuse (EU)

MiCA introduces a crypto market-abuse framework:

• Prohibition of insider dealing.
• Prohibition of unlawful disclosure of inside information.
• Prohibition of market manipulation.
• Surveillance obligations for trading platforms.

However, the EU crypto MAR regime is somewhat lighter than traditional securities MAR.

2. The UK Framework: AML Registration Today, Full Authorization Tomorrow

The UK currently operates a two-stage regulatory structure:

Stage 1: AML Registration (Active)

Crypto firms must register with the Financial Conduct Authority (FCA) under AML regulations to operate legally.

This is not full authorization but compliance with:

• KYC/AML controls
• Suspicious activity reporting
• Financial crime risk management

The FCA has rejected a high percentage of applicants, demonstrating strict supervisory scrutiny.

Stage 2: Full FSMA Authorization (Planned, ~2027)

The UK government is implementing a broader regime under the Financial Services and Markets Act (FSMA).

Activities likely to require authorization:

• Operating trading platforms
• Dealing in cryptoassets
• Custody services
• Lending and staking intermediation
• Arranging transactions
• Certain centralized DeFi models

This will transform crypto firms into FCA-authorized financial services entities.

Key Differences Between MiCA and the UK Model

3. Strategic Impact for Cross-Border Crypto Providers

Providers operating in both jurisdictions must prepare for:

• Dual authorization processes
• Separate prudential capital requirements
• Distinct reporting obligations
• Divergent consumer-protection regimes
• No passport equivalence between EU and UK

The UK is deliberately not mirroring MiCA. Instead, it is embedding crypto into the traditional financial regulatory architecture.

This could lead to:

• Higher governance expectations in the UK
• More granular supervisory engagement
• Broader enforcement perimeter

6. Regulatory Convergence or Competitive Divergence?

The EU model prioritizes harmonization and passporting.

The UK model prioritizes supervisory control and integration into mainstream financial regulation.

While objectives are aligned (consumer protection, market integrity), execution differs.

There is currently no regulatory equivalence regime between MiCA and the UK framework.

Cross-border crypto activity therefore requires parallel compliance architecture.

Conclusion: Two Systems, One Compliance Reality

The EU offers regulatory clarity through MiCA, but with strict filtration and capital requirements.

The UK offers phased integration into traditional financial regulation, potentially with broader activity coverage.

Crypto providers must now operate as regulated financial institutions — not experimental technology platforms.

The era of light-touch crypto regulation in Europe and the UK is over.
