What happened

The European Securities and Markets Authority launched a coordinated review of crypto custody providers on 8 July 2026. National regulators will examine how authorised firms manage private keys, storage, and operational risks under the EU's MiCA framework.

Confirmed

Global impact / market context

The EU regulator is checking how crypto‑custody firms protect private keys and run their operations, which could tighten rules and affect the safety and cost of storing digital assets for investors.

Confirmed

The review comes as the MiCA (Markets in Crypto‑Assets) regime finishes its transition period, meaning firms must now fully comply with the new EU crypto rules that aim to standardise the market.

Confirmed

What to watch

  1. National regulators may require custody firms to upgrade key‑management systems, which could raise operating expenses and lead to higher fees for clients. Proposed
  2. Firms that cannot meet the new security standards might lose their authorisations, potentially reducing the number of crypto‑custody providers in the EU. Analyst inference
  3. Investors should monitor any announced penalties or remediation plans, as they could signal which providers are better positioned under MiCA and affect capital allocation decisions. Analyst inference
