CSSF Concludes Thematic AML Review of Fund Distribution, Faults Three Quarters of Sample
The supervisor's findings, published Wednesday, pressure ManCos to overhaul source-of-wealth controls before the 2026 SREP cycle.
The Commission de Surveillance du Secteur Financier (CSSF) on Wednesday concluded an 18-month thematic review of anti-money-laundering controls across Luxembourg's fund-distribution chain, identifying material weaknesses at 73% of the 84 management companies in the supervisory sample.
The headline finding: while screening of investors at onboarding has improved markedly since the 2021 review, ongoing-monitoring and source-of-wealth verification remain "patchy and procedurally underweight," in the regulator's phrasing. Sixty-one out of 84 ManCos received supervisory letters, and the CSSF said it is opening enforcement proceedings against an unnamed subset.
Where the gaps are
Three structural weaknesses recur: reliance on intermediaries' AML files without contractual access rights; inconsistent treatment of nominee structures originating in jurisdictions on the EU's grey list; and weak secondary checks on cumulative subscription thresholds.
What ManCos should expect next
The 2026 SREP cycle will give CSSF inspectors access to the same documentation under a tighter scoring rubric. Industry counsel at Arendt & Medernach told Étude they expect at least a dozen ManCos to face dissuasive financial sanctions in 2026 — up from three in 2024.
