European stocks finished lower on Wednesday, September 23, 2026, as a surge in global bond yields pressured markets. The primary driver was stronger-than-expected US Purchasing Managers' Index (PMI) data, which saw the flash composite PMI jump to 58.4 from 56.0, suggesting robust economic growth. This, combined with persistent inflation concerns, put further Federal Reserve interest rate hikes into focus, consequently lifting bond yields across both the US and Europe. Fed officials, including Richmond Fed President Tom Barkin and Governor Michael Barr, indicated that inflation could be stubborn and further policy adjustments might be necessary.

European markets also saw growth, with flash PMIs indicating continued expansion across France, Germany, the Eurozone, and the UK. For instance, Eurozone services rose to 53.0 from 51.6, beating estimates, and German services sharply improved to 52.9 from 49.7. Despite these encouraging growth readings, the rise in bond yields overshadowed the positive economic data, leading to a decline in stock indices. Germany's DAX fell by 0.66% to 25,410.64, France's CAC 40 was down 0.39% to 8,123.42, and the UK's FTSE 100 edged down 0.03% to 10,705.25. Spain's IBEX 35 dropped 0.62% to 19,632.20, and Italy's FTSE MIB decreased by 0.21% to 51,897.50.

Bond yields climbed significantly, with Germany's 10-year yield increasing by 11.6 basis points to 3.560%, France's by 16.8 basis points to 4.660%, and Italy's by 16.0 basis points to 4.506%. The US 10-year Treasury yield also rose by 11.6 basis points to 5.083%. This yield surge bolstered the US dollar against major currencies, with the euro falling 0.48% to $1.1392 and the pound dropping 0.68% to $1.3248. Gold and silver, considered non-interest-bearing assets, declined, with gold falling $76.70 (1.76%) to $4,282.80 and silver dropping $2.49 (3.72%) to $64.53. Rising yields make interest-bearing assets more attractive and a stronger dollar further weighs on precious metals.

Oil prices, however, were an exception, with West Texas Intermediate (WTI) rising $2.91 (approximately 3.24%) to $92.75, recovering from near a technical swing level of $88.72. The broader pan-European Stoxx 600 index ended 0.44% lower at 639.92, reversing earlier gains. Energy stocks were the only sector on the Stoxx 600 to show gains, increasing by 1.3%, while heavyweight bank stocks fell 0.4%. Insurance and construction/materials sectors experienced the steepest declines, down 1.7% and 1.3% respectively. Geopolitical tensions, specifically the lack of progress in US-Iran peace talks and upcoming US-China discussions, also contributed to market caution.
