FRANKFURT (dpa-AFX) - Concerns over the conflict involving Iran continue to weigh on investor sentiment this Monday, keeping the Dax under pressure as oil prices climb further. Approximately two hours before the Xetra open, broker IG signaled a 0.2 percent decline for the German benchmark index, pointing to a level of 24,289 points. This suggests the Dax will continue to retreat from its post-February peak of 25,152 points reached just last week.

Diplomatic efforts between the U.S. and Iran to end the hostilities remain deadlocked. U.S. President Donald Trump described Iran's latest response to the American proposal for a diplomatic resolution as 'completely unacceptable' and issued further threats against the Islamic Republic.
