What is MiCA and What Does It Mean for Finance Teams?

Introduction

If you work in finance and your organisation operates in the EU, or deals with EU-based counterparties, MiCA is now your problem to understand. The Markets in Crypto-Assets Regulation (Regulation (EU) 2023/1114) is the most significant piece of crypto regulation ever enacted and it is already in force.

This article explains what MiCA is, what it requires, and what your finance function needs to do to stay compliant.

What is MiCA?

MiCA is an EU-wide regulatory framework for crypto-assets and the businesses that issue or provide services relating to them. It was adopted in May 2023 and came into full effect on 30 December 2024.

Before MiCA, crypto regulation in the EU was fragmented — different member states had different rules, creating a patchwork that was difficult for businesses to navigate. MiCA replaces this fragmentation with a single, harmonised framework applying across all 27 EU member states.

MiCA covers:

• Asset-Referenced Tokens (ARTs) — tokens referencing multiple assets (e.g. a basket of currencies)
• E-Money Tokens (EMTs) — stablecoins pegged to a single fiat currency
• Other crypto-assets — including utility tokens and most cryptocurrencies not covered by existing financial services regulation

Note: MiCA explicitly excludes security tokens (which fall under MiFID II), DeFi protocols, and NFTs (for now — the Commission is monitoring this).

Key Requirements Under MiCA

Authorisation and Licensing

Any business providing crypto-asset services in the EU — exchanges, custodians, portfolio managers, advisers — must be authorised as a Crypto-Asset Service Provider (CASP). This involves applying to the national competent authority (e.g. the Central Bank of Ireland, BaFin in Germany) and meeting ongoing capital, governance, and conduct requirements.

If your organisation provides any of these services, or is considering doing so, the authorisation process needs to be on your roadmap now.

Stablecoin Rules (ARTs and EMTs)

Issuers of stablecoins face the most stringent requirements under MiCA. Key obligations include:

• Publishing a detailed white paper with information about the issuer, the token, and associated risks
• Maintaining a reserve of assets to back the token at all times
• Segregating reserve assets and holding them with authorised credit institutions or custodians
• Quarterly reporting on reserve composition
• Volume limits for EMTs not denominated in euros — once daily transaction volume exceeds €200 million, the issuer must halt issuance

From a finance team perspective, if your organisation holds stablecoins issued by EU entities, you need to verify those issuers are MiCA-compliant. Non-compliant stablecoins may need to be unwound.

Disclosure and White Paper Requirements

Any public offer of crypto-assets (other than ARTs/EMTs, which have their own rules) requires a crypto-asset white paper. This must include information on the issuer, the project, the rights attached to the token, and prominent risk warnings. The white paper must be notified to the competent authority before publication.

Market Conduct and Insider Dealing

MiCA introduces market abuse rules for crypto-assets — prohibition on insider dealing, unlawful disclosure of inside information, and market manipulation. These rules apply to anyone involved in crypto-asset markets, not just licensed CASPs. Finance professionals who have access to material non-public information about token projects or issuers need to be aware.

Key Timelines

• June 2024: Title III (ARTs) and Title IV (EMTs) came into force
• 30 December 2024: Full MiCA application — all titles including CASP requirements
• Transitional periods: Member states could allow existing crypto businesses to continue operating under national regimes for up to 18 months (so until mid-2026 at the latest)

What Finance Teams Need to Do Now

1. Map your crypto exposure: Identify all digital asset holdings, transactions, and service relationships your organisation has with CASPs
2. Verify CASP authorisation: Check that any exchanges, custodians, or service providers you use are authorised under MiCA (or operating under a valid transitional exemption)
3. Review stablecoin holdings: Assess whether any stablecoins held are compliant with MiCA's reserve and issuer requirements
4. Update internal policies: Your digital assets policy, AML procedures, and market conduct policies should all reference MiCA obligations
5. Train staff: Finance, compliance, and legal teams need to understand MiCA basics — especially market abuse rules which apply broadly
6. Monitor ESMA guidance: The European Securities and Markets Authority (ESMA) is issuing ongoing technical standards under MiCA — subscribe to updates

MiCA and UK Finance Teams

The UK has not adopted MiCA — post-Brexit, the UK is developing its own crypto regulatory framework under the Financial Services and Markets Act 2023. However, if you work for a UK firm that operates in the EU, or that deals with EU-based CASPs or clients, you will need to understand MiCA's requirements as they apply to your EU counterparties and activities.
