Germany’s Commerzbank logged an operating profit of €2.1 billion (around $3.0 billion) in the first six months of 2011, up from €1.0 billion a year before, while the Frankfurt-listed bank booked €760 million of impairments linked to Greek debt.

The bank said it has made “considerable progress” in its Private Customers, Mittelstandsbank, Central & Eastern Europe and Corporates & Markets segments.

The bank, which received public funds in a bailout in the aftermath of the 2008 credit crisis, has had to spin off non-domestic assets as a condition of such aid, selling businesses such as UK-based private bank Kleinwort Benson, for example.

In the Private Customer business, the operating profit has increased over the second quarter to 30 June by €66 million to €79 million. Positive factors included the improved interest rate environment and a drop in loan loss provisions, it said.
