The Luxembourg Commission de Surveillance du Secteur Financier published its monthly statistics on Luxembourg undertakings for collective investment (UCIs), reporting total net assets of EUR 5,618.885 billion at 30 April 2025, down 2.28% from 31 March 2025 but up 3.64% over the past 12 months. The EUR 130.894 billion monthly contraction reflected a small net outflow and a larger negative market impact. Net capital investment was negative at EUR 4.342 billion (-0.08%), while the development of financial markets contributed a further EUR 126.552 billion decrease (-2.20%). The population covered totalled 3,112 UCIs, including 2,060 umbrella structures with 12,402 sub-funds, for a total of 13,454 active fund units in the financial centre. Equity UCIs saw overall net outflows with European equities the main exception, while fixed income UCIs recorded net inflows driven by money market categories and the largest outflows in high yield bonds; April’s market effects were framed around volatility linked to US trade tariffs and their partial suspension, widening credit spreads and a seventh consecutive 25 basis point European Central Bank rate cut. During the month, seven UCIs were added to the official list and nineteen were removed, comprising additions of one UCITS, three Part II UCIs, two specialised investment funds and one SICAR, and removals of nine UCITS, seven specialised investment funds and three SICARs.
