Commerzbank's market share is too narrow, says CEO

Commerzbank's market share is too small and organic growth is too slow, the lender's chief executive told employees as he weighs a tie-up with Deutsche Bank. "That's why we are also currently look at alternative options for growth," CEO Martin Zielke told employees, according to comments posted on the bank's intranet and seen by Reuters.

"The alternative of doing nothing is not an option," he said. Bloomberg first reported the comments.
