Tensions with Iran Weigh on Global Markets

European stocks reversed early gains on Monday as escalating tensions between Washington and Iran outweighed relief from dovish U.S. Federal Reserve expectations.

The Stoxx Europe 600 fell 0.1%, while Germany's DAX, the UK's FTSE 100, and France's CAC 40 each slipped 0.1%.

Japanese stocks were mixed as weaker-than-expected second-quarter GDP growth weighed on sentiment amid ongoing geopolitical and inflation concerns.

The U.S. dollar fell 0.3% to a more than two-month low of 99.33, while gold prices edged higher, trading just below $4,400 an ounce.
