MiCA CASP authorisation in Luxembourg (CSSF)

Why teams look at Luxembourg

Luxembourg is a major European financial center, especially for funds and institutional custody, with a regulator experienced in sophisticated cross-border structures. It also registered crypto-asset service providers before MiCA. Under MiCA’s crypto-asset service provider regime, applying from 30 December 2024, the Commission de Surveillance du Secteur Financier (CSSF) is the authorising authority. Luxembourg suits institutional and custody-oriented firms that value a credible, finance-deep jurisdiction.

The authorisation route

A firm that is not already an EU-authorised financial entity applies to the CSSF for authorisation as a CASP under Article 62. A firm already authorised under EU financial law can use the lighter Article 60 notification.

Under Article 63 the CSSF has 25 working days to confirm completeness and then 40 working days to decide once the file is complete.

What the CSSF expects

Local substance

A registered office in Luxembourg and management effectively based there under Article 59(2).

Governance and fit-and-proper

Collective crypto-asset competence and sufficient time under Article 68, with detailed assessment of directors and qualifying shareholders.

Custody and client assets

Luxembourg’s institutional-custody depth means close attention to segregation, reconciliation, the custody policy, and strict liability for loss under Article 75.

Prudential safeguards

Own funds, an insurance policy, a comparable guarantee, or a mix under Article 67, at the higher of the class minimum or one quarter of fixed overheads.

Capital and the Article 67 question

The minimum is 50,000 euro, 125,000 euro, or 150,000 euro depending on the services you are authorised for, or one quarter of the previous year’s fixed overheads if higher. If you are weighing insurance against capital, build the evidence first: see the CASP insurance evidence pack and own funds vs insurance.

Coming from a CSSF crypto registration

Firms registered under the pre-MiCA CSSF crypto regime do not convert automatically to a MiCA authorisation. They transition through a process the CSSF manages within a national transitional window. Confirm the current cut-off date and the exact transition steps with the CSSF.

Transitional dates have moved at the member-state level. Confirm any date against current CSSF guidance before planning around it.

FAQ

Is a Luxembourg CASP licence valid across the EU?

Yes. A CASP authorisation passports to all 27 member states under Article 65. You authorise in Luxembourg and notify the host states before providing services there.

Why do institutional firms choose Luxembourg?

Deep fund and custody infrastructure, a regulator experienced with complex cross-border structures, and a credible finance brand. MiCA substance rules still apply.
