The DAX 40 fell 0.4% to around 26,140 on Tuesday, the lowest since August 24, as September began with investors wary that a prolonged US-Iran conflict could fuel energy-driven inflation and prompt tighter monetary policy. Oil prices continued to rise on the back of flared-up hostilities in the Middle East, with traders increasingly pricing in interest rate hikes by major central banks. Eurozone flash inflation figures are expected to reinforce expectations for near-term rate hikes by the ECB. Sectorally, energy-sensitive industrials, banks and autos were the hardest hit. Software giant SAP led losses among stocks, slipping 2.5%. Rheinmetall, MTU Aero Engines, Scout 24, BMW, Mercedes-Benz Group and Volkswagen posted losses between 0.8%-2.1%. Deutsche Bank and Commerzbank fell more than 1% each.
