The lender said that the decline in profit for the first six months is mainly due to the weaker interest rate environment and higher loan loss provisions.

Commenting on the financial performance, Commerzbank board of managing directors chairman Martin Blessing said that the company is incorporating the measures of its strategic program and it is expected that the result will be visible in future.

"Thus we are establishing the basis for a further improvement in the future profitability of the Bank," Blessing added.

For the first six months ended on 30 June 2013, the bank posted revenues before loan loss provisions of €4.8bn, which was €400m lesser compared to €5.2bn during the comparable period, earlier year.

The Private Customers segment operating profit was €123m, compared to €167m, while revenues before loan loss provisions stabilized and stood at €1.7bn.

As per the phase-in regulations of Basel 3, the ratio was at 10.3%, as the end of June 2013, compared to 10.1%, as the end of 31 March 2013.

Mittelstandsbank operating profit reduced to €542m, against €874m, while the Central & Eastern Europe segment operating profit was slashed to €127m versus €146m, during the year ago period.
