Navigating MiCA: a guide for banks entering the crypto era

The digital asset landscape is changing – and banks are no longer on the sidelines.
With the Markets in Crypto-Assets (MiCA) now fully in force across the EU, traditional financial institutions must now grapple with the same expectations of transparency, accountability, and compliance as crypto-native players. For banks and neobanks expanding their digital asset services, MiCA is not just a regulatory hurdle – it’s a roadmap to trust, growth, and institutional credibility.

What is MiCA?

MiCA is the EU’s first comprehensive regulatory framework for crypto-assets. Designed to harmonize rules across member states, it focuses on ensuring consumer protection, market integrity, and financial stability in digital asset markets.

MiCA timeline (updated July 2026):

• 9 June 2023 – Published in the Official Journal.  Entered into force in June 2023.
• June 2024 – Title III & IV provisions on stablecoins and e-money tokens began applying.
• December 2024 – MiCA’s CASP regime (Title V) became applicable EU-wide. Providers already operating under national law before this date could continue under transitional (“grandfathering”) arrangements – length varied by Member State – until authorised, refused, or 1 July 2026, whichever came first.
• 1 July 2026 – Maximum end date for the transitional regime under Article 143. Providers that were still relying solely on pre-MiCA national registration could no longer provide in-scope crypto-asset services after this date unless they had obtained MiCA authorisation or another lawful basis to operate. Several Member States ended their national transitional periods earlier.

Why does it matter for banks?

While much of the regulatory focus has historically been on exchanges and crypto-native startups, traditional banks are increasingly in scope – especially as they begin offering custody, trading, or tokenized asset services.

Banks may not always consider themselves crypto asset service providers (CASPs), but under MiCA, activities like safekeeping private keys, executing crypto orders, or enabling access to trading platforms fall within the regulatory perimeter. As the EU moves to harmonize the treatment of crypto-assets across all providers, banks fall within that same regulatory perimeter as crypto-native businesses like exchanges – though, as covered below, banks typically get there via a different authorisation route.

Whether launching digital asset services in-house or via partnerships, banks offering crypto-related activities will fall within MiCA’s regulatory perimeter – either through the standard CASP authorisation, or, for credit institutions, through the lighter-touch Article 60 notification route covered below.

Key reasons why banks must prepare:

• Regulatory parity: MiCA removes the grey zone. Offering crypto without meeting MiCA standards risks penalties and enforcement.
  
  
• Rising consumer demand: Clients expect both crypto access and the security and trust often associated with traditional banking.
  
  
• Future-proof infrastructure : Building controls for crypto now also prepares treasury and ops teams for tokenised securities and on-chain collateral that will likely follow.

MiCA’s requirements are driven principally by the asset and activity being provided, rather than whether the provider is crypto-native or a traditional financial institution. Banks therefore fall within the regulatory perimeter when they provide covered crypto-asset services, although credit institutions use the Article 60 notification route and are exempt from parts of the standard CASP authorisation framework.

Key MiCA requirements for banks

MiCA introduces a structured compliance framework, but many of its requirements rely on interpretation by national regulators—making adaptability critical.

Here are the major areas where banks must prepare:

Authorization & registration

Before offering crypto services, CASPs must obtain CASP authorization from their national competent authority (NCA). This includes submitting governance documentation, operational workflows, internal controls, and evidence of robust compliance capabilities.

That said, banks and certain other financial entities (investment firms, e-money institutions, etc.) can sometimes leverage their existing licenses to provide crypto services by notifying their regulator instead of undergoing a full new CASP authorization (Article 60).

Capital adequacy

Credit institutions using the Article 60 route are exempt from MiCA’s separate Article 67 prudential-safeguard requirement, but must continue to identify, assess and capitalise their crypto-related risks under the applicable banking prudential and supervisory frameworks.

Other CASPs must maintain prudential safeguards equal to the higher of the applicable permanent minimum capital requirement – between €50,000 and €150,000 depending on the services provided – and one quarter of the preceding year’s fixed overheads.

Client asset segregation

Banks offering custody services are expected to implement wallet architecture that supports segregation. This often involves using distinct blockchain addresses or sub-accounts for client holdings versus the bank’s treasury holdings, or maintaining robust on-chain tagging and off-chain bookkeeping to delineate ownership. MiCA does not prescribe the technical method, but the arrangements must be sufficient to ensure clear ownership.

MiCA mandates strict segregation of client-held crypto-assets from the firm’s proprietary holdings, both technically and legally. This applies to hot and cold wallet structures.

Example: Each client’s on-chain assets must be independently identifiable, with sub-ledgers reflecting balances that can be reconciled against on-chain data.

Record keeping & periodic reporting

Banks must maintain detailed, immutable records for a period of 5 years (or up to 7, where requested by a NCA prior to 5 years being elapsed- Article 68 section 9) of:

• All crypto transactions, activities, services and orders
• Wallet balances (internal & external)
• Reconciliation logs
• Communications and complaints
• Governance and compliance records

Daily reconciliation is a strong operational practice, although MiCA does not prescribe a universal daily reconciliation frequency. Custodians must also provide clients with a statement of their crypto-asset positions at least once every three months and upon request.

Risk management & internal governance

MiCA requires comprehensive internal controls across:

• Operational risk: such as procedures for managing system outages, transaction errors, wallet malfunctions, and other operational incidents.
  
  
• Custody controls: a formal custody policy must be in place to prevent loss or theft of crypto assets/keys, with defined processes for key generation, storage (e.g. use of HSMs or multi-signature wallets), and transaction authorization.
• Market abuse prevention (including insider trading): firms professionally arranging or executing crypto-asset transactions are required to have systems in place to detect and prevent market abuse, and to report suspicious orders and transactions (Article 92). 

Operational resilience under DORA 

Since 17 January 2025, the Digital Operational Resilience Act (DORA) has applied alongside MiCA. Banks are already in scope as credit institutions, while authorised CASPs are also covered as financial entities. In practice, DORA adds an ICT-focused control framework covering operational resilience, incident management, testing and third-party technology risk.

• ICT risk management frameworks covering crypto infrastructure, wallets and custody systems, not just traditional banking IT.
• Incident classification and reporting on timelines that are tighter than anything MiCA requires on its own.
• Third-party ICT oversight extending to custodians, node operators, and blockchain data vendors the bank relies on.
• Resilience testing at a cadence proportionate to the scale of the crypto activity. 

For banks, this isn’t a side track to MiCA authorisation – MiCA and DORA are closely connected: MiCA expressly incorporates DORA requirements for ICT systems and business continuity, while Article 60 notifications require technical documentation on ICT systems and security arrangements.

White paper for issuance of crypto-assets:

If a bank (or any entity) issues a crypto-asset or offers one to the public, MiCA often (with some exemptions) requires a crypto-asset white paper that includes detailed information about the project, underlying technology, risks, rights of investors, and costs/fees associated with the asset.

For example, if a bank were to issue its own stablecoin that qualifies as an electronic-money token (EMT), it would need to publish a MiCA-compliant whitepaper disclosing all relevant risks (volatility, tech risk, governance, etc.) and any fees. 

AML & CTF compliance

Any MiCA-regulated activity must meet EU Anti-Money Laundering (AML) and Countering the Financing of Terrorism (CTF) standards, including:

• Customer due diligence (CDD): banks must conduct full KYC on customers using crypto services, verifying identity, assessing the purpose of accounts, and understanding the source of funds/wealth as appropriate.
  
  
• Transaction monitoring: banks are expected to implement systems to monitor crypto transactions for red flags such as structuring (smurfing), sudden large movements, or transfers involving known suspicious addresses.
  
  
• Suspicious activity reporting: as with any financial activity, if a bank detects signs of money laundering or terrorist financing in its crypto business, it must file suspicious transaction reports with the national Financial Intelligence Unit (FIU).
  
  
• Exception to the typical travel rule: alongside MiCA, the EU approved revisions to the Transfer of Funds Regulation (TFR) which require that originator and beneficiary information accompany all crypto-asset transfers between CASPs, regardless of amount​. This goes beyond the FATF’s recommendation (which set a €1000 threshold)

Challenges and opportunities for banks

Key challenges

• Data fragmentation: banks must reconcile on-chain and off-chain records across siloed systems.
  
  
• Legacy infrastructure: traditional core banking systems weren't designed to ingest and classify crypto data.
  
  
• Unclear guidance: the core MiCA framework is now settled, but supervisory convergence is still developing – particularly on reporting formats, the MiCA/DORA overlap, and treatment of newer structures such as tokenised deposits and novel custody models.
  
  

Opportunities

• Client trust: MiCA compliance signals safety, professionalism, and transparency, helping differentiate credible institutions from riskier players in the crypto space.
  
  
• New services: token custody, stablecoin integration, and crypto investment services are easier to pursue within a clear legal framework.
  
  
• Regulatory advantage: early movers can help shape best practices and build lasting relationships with regulators, establishing market leadership.
