The Luxembourg Commission de Surveillance du Secteur Financier published aggregated results for Luxembourg’s banking sector for the first half of 2025, noting that a merger between two banks created a break in series that materially distorts some year-on-year percentage changes in its table. It estimates that profit before provisions and taxes fell by 5% year-on-year, alongside a higher cost-to-income ratio of 45.3% (42.1% in 2024). Net interest income declined by 4.6% to 5,159.2, a decrease observed in 61% of banks and attributed to falling interest rates since the second half of 2024. Net fee and commission income increased by 2.1% to 3,169.4 and other net income rose by 19.7% to 918.8. Reported staff costs and other general expenses increased to 1,837.4 and 2,353.2, but the CSSF said the merger overstates their growth and estimates that, after adjustment, staff costs would have grown by 3% and other general expenses by 2%. As at 30 June 2025, 14 of 118 banks recorded negative results; the sector perimeter excludes foreign branches and subsidiaries.
