CSSF Licensing Explained: From Application to Operational Launch

CSSF Licensing Is Rigorous — But Highly Predictable

Luxembourg’s CSSF (Commission de Surveillance du Secteur Financier) is one of the most respected fund regulators in the world.
Its licensing process is:

• Transparent
• Structured
• Documentation-driven
• Substance-oriented

Unlike some jurisdictions where personal relationships play a larger role, Luxembourg places primary importance on:

• Governance
• Operational substance
• Risk management
• Internal controls
• Technology infrastructure
• Independence of functions

This guide explains the full CSSF licensing cycle, from the initial planning phase all the way to operational launch.

1. Who Needs CSSF Authorization?

The CSSF regulates:

A. Alternative Investment Fund Managers (AIFMs)

• Infrastructure fund managers
• Hedge fund managers

B. UCITS Management Companies

• Retail and institutional liquid funds
• Multi-asset funds
• SICAV/umbrella UCITS structures

C. Investment Firms Providing MiFID Services

Some AIFMs and ManCos may also apply for limited MiFID permissions.

CSSF may conduct onsite inspection visits.

Stage

Duration

• Pre-Application | 1–3 months
• Application Review | 6–12 months

• Operational Setup | 1–3 months
• Go-Live | Month 13–15

Large AIFMs or UCITS ManCos may take longer.

Required Tools
