CAC 40 Slips as Eurozone Bond Yields Climb to Multi-Decade Highs

The CAC 40 index fell by 0.39% to close at 8,123.41 on Wednesday, September 23, 2026, after a mixed session marked by an early gain followed by a steady decline.

The index opened higher due to falling oil prices and upbeat French services data, but this momentum was short-lived as sovereign bond yields surged to multi-decade highs in response to stronger-than-expected eurozone PMI readings.

This rise in yields led to increased expectations of further ECB rate hikes, which weighed heavily on the CAC 40, particularly on luxury and consumer stocks such as L'Oreal and LVMH.
