Deutsche Bank earned net income of €1.4bn ($2.09bn) in the third quarter to the end of September, Germany’s biggest bank said on Wednesday as it brought forward key details of its expected quarterly results.

The results were in line with those of the second quarter and confirmed the consistent earnings at Deutsche Bank in spite of any lingering effects of the financial crisis. But investors reacted with caution, sending shares in the bank 4 per cent lower in morning trading in Frankfurt.
