MiCA Article 100 professional secrecy checklist

A source-backed, conservative evidence checklist for CASPs mapping professional-secrecy assumptions around competent-authority exchanges, business or operational information, economic or personal affairs, and supervisory-response handoffs.

What Article 100 changes operationally

Professional secrecy: ESMA's Interactive Single Rulebook publishes Regulation (EU) 2023/1114 Article 100 with the title “Professional secrecy”. Public Article 100 text states that information exchanged between competent authorities under MiCA that concerns business or operational conditions and other economic or personal affairs is considered confidential and subject to professional secrecy requirements.

Article 100 also describes bounded disclosure contexts, including where the competent authority states at the time of communication that information may be disclosed, where disclosure is necessary for legal proceedings, or where cases are covered by national taxation or criminal law. For CASP evidence packs, the safe operational move is a provenance and handling log, not a conclusion that any record can or cannot be shared.

This page is a record-handling checklist. It is not a legal interpretation, disclosure recommendation, supervisory-response instruction, authorisation opinion, tax or criminal-law assessment, provider endorsement, broker recommendation, or assurance about any firm, authority, information exchange, confidentiality status, legal-proceeding exception, taxation case, criminal-law case, person, communication, or fact pattern.

FAQ

What does MiCA Article 100 cover?

Article 100 is publicly titled “Professional secrecy”. Public text covers confidentiality and professional-secrecy requirements for information exchanged between competent authorities under MiCA, especially information concerning business or operational conditions and other economic or personal affairs.

Why does Article 100 matter for CASP evidence packs?

Supervisory cooperation, information requests, register updates, and other-authority maps can contain sensitive operational, economic, or personal-affairs material. A CASP evidence pack should preserve provenance, handling status, review ownership, and unresolved external-advice questions.

Does this page decide whether information may be disclosed?

No. This page does not decide disclosure status, confidentiality status, or professional-secrecy outcomes. It helps teams preserve a source-backed handling record for qualified legal, regulatory, competent-authority, partner, broker, insurer, auditor, or internal-risk review.
