Tracked byBrokerlist Editorial · Independent review teamUpdated
The Commission de Surveillance du Secteur Financier (CSSF) is Luxembourg's integrated financial-services regulator covering banking, investment firms, fund managers (UCITS and AIF) and other financial-sector entities. Banque centrale du Luxembourg handles monetary policy under the European Central Bank framework; the Commissariat aux Assurances (CAA) supervises insurance separately.

- Dispute resolution
- CSSF mediation is non-binding — recommendations are issued but firms are not legally obligated to comply. Luxembourg courts are the ultimate recourse for unresolved disputes. EU cross-border disputes coordinate via FIN-NET, the network of national financial-services ombudsmen.
- Editor notes
- Luxembourg is the EU's top fund-domicile (UCITS and AIF). For retail FX/CFD activity, CSSF-licensed brokers are relatively uncommon — most international brokers serving Luxembourg residents use CySEC EU passports. CSSF's focus tilts toward institutional fund administration and private banking rather than retail leveraged FX. Luxembourg-domiciled banks may offer FX/derivatives to private-banking clients but rarely market retail-style leveraged FX.
