The Luxembourg Commission de Surveillance du Secteur Financier (CSSF) regulates banks, investment firms, fund managers, payment institutions, and professional fund service providers in one of Europe's largest financial centres.
Luxembourg's CSSF supervises over 4,000 financial entities — the largest fund domicile in Europe (and second globally after the US) and a leading location for investment banking, private banking, and payments infrastructure. The CSSF is known for rigorous but commercially pragmatic regulation, making Luxembourg the jurisdiction of choice for EU fund management, payment services, and financial holding structures.
Marensa Advisory advises on CSSF regulatory strategy for non-EU financial groups establishing Luxembourg presence — fund managers, payment institutions, investment firms, and digital asset businesses.

Luxembourg provides a single regulated presence from which financial groups can access the entire EU market under AIFMD, UCITS, MiFID II, PSD2, EMI, and MiCA passports — making it the most efficient European regulatory entry point for non-EU groups.
Marensa Advisory advises on Luxembourg CSSF licensing strategy with a full understanding of the EU regulatory landscape — ensuring that the Luxembourg entity is structured to maximise the commercial value of the EU passport.

Yes. CSSF requires Luxembourg payment institutions to have genuine substance — including at minimum an approved management function and sufficient Luxembourg-based governance to satisfy CSSF's substance expectations.
Crypto-asset service providers operating in Luxembourg must register as CASPs under MiCA. Luxembourg EMIs and investment firms already licensed under existing directives may benefit from transitional provisions, but full MiCA compliance is required by the applicable MiCA transitional deadlines.
CSSF accepts applications in French, German, English, or Luxembourgish. In practice, most non-EU applicants file in English.
