Frankfurt-based Commerzbank increased its private banking client base by 6 per cent during 2006 to end the year with 22,400 clients, according to the bank’s annual report. Assets under management rose by 12 per cent to €25.3 billion. Commerzbank now has private banking 37 offices in Germany. Separately, Commerzbank is examining all strategic options for its French asset management unit CCR, according to the asset management division's head Achim Kassow. Commerzbank may sell the unit, invest in it to boost growth or maintain the status quo, Mr Kassow said. Kassow also said the company is examining options for its Asian asset management business, whose contribution is “only marginal”.
