The Luxembourg Commission de Surveillance du Secteur Financier published its September 2025 statistics for Luxembourg undertakings for collective investment (UCIs), covering UCIs under the 2010 Law, specialised investment funds and SICARs. Total net assets stood at EUR 6,025.044 billion as at 30 September 2025, up 1.26% from 31 August 2025 and 6.46% over the past 12 months. The EUR 74.753 billion monthly increase combined EUR 9.104 billion of positive net capital investment and a EUR 65.649 billion positive market effect. The number of UCIs fell to 3,071 from 3,079, with 2,052 umbrella structures representing 12,327 sub-funds and 13,346 fund units in total. CSSF attributed September’s market backdrop to continued equity gains and a 25 bps Federal Reserve rate cut, alongside unchanged European Central Bank rates, and noted that fixed income UCIs delivered positive performance with net inflows across bond categories while EUR and global money market categories recorded outflows. Six UCIs were registered on the official list during the month and 14 were deregistered.
