Fresh US-Iran military strikes drive up oil prices

European shares fell on Monday as fresh US-Iran military strikes drove oil prices and bond yields higher, though the benchmark STOXX 600 marked its fifth consecutive monthly gain.

The pan-European STOXX 600 was down 0.6% at 651.1 points on the day, with trading volumes subdued as London markets were closed for a bank holiday.

Germany's DAX dropped 1.2%, the steepest decline among major regional indexes, after data showed German inflation accelerated in August as the Iran conflict lifted energy prices. However, the increase was smaller than expected and core inflation remained stable.

US forces struck two missile launchers on Iran's Larak Island in the Strait of Hormuz on Sunday, the first known US military action against Iran since late July, prompting Tehran to launch attacks on two US air bases in Jordan, Iranian media reported.

The rise in energy prices has reinforced inflation concerns at a time when investors are already bracing for further policy tightening. Still, a strong earnings season and continued enthusiasm around artificial intelligence helped the STOXX 600 to rise 0.3% in August.
