Erste Group board member Thomas Schaufler will take over Commerzbank's retail banking division, while Joerg Oliveri del Castillo-Schulz, currently an independent consultant, will become chief operating officer.

Germany's No. 2 lender is trying to turn over a new leaf under new Chief Executive Manfred Knof. It is carrying out a 2 billion euro ($2.36 billion) restructuring that also involves hundreds of branch closures.

Schaufler assumes the retail responsibilities of Sabine Schmittroth, who will continue to oversee human resources.

Oliveri del Castillo-Schulz takes over the COO job from Joerg Hessenmueller, who was also responsible for technology.

Hessenmueller will resign, Commerzbank said.

That move comes after the bank in July abandoned a project to outsource securities settlement to HSBC and, as a result, wrote off 200 million euros in the second quarter.

The German lender's supervisory board agreed on the moves at a meeting on Wednesday.

Commerzbank, which is still partially owned by the state after a bailout during the financial crisis more than a decade ago, is expected to post a loss for the full year, according to analysts.
