Frankfurt’s DAX 40 fell 0.3% to trade below 25,500 on Tuesday, reversing some of its strong start to the week in line with other European markets. Rising oil prices and geopolitical risks kept investors cautious as attention shifted to the UN General Assembly for signs of diplomatic progress toward ending the Iran conflict. US President Donald Trump is scheduled to address the assembly later Tuesday and has left open the possibility of meeting Iranian President Masoud Pezeshkian.
