Deutsche Bank (DBKGn.DE) faces a long and costly battle, analysts say, to sell Postbank (DPBGn.DE) and pare investment banking, the new strategic goals it outlined late on Friday. Deutsche will face an especially difficult challenge in selling off Postbank without having to post losses. “We’re worried about jobs at Postbank,” Carsten Schneider, finance expert and deputy SPD parliamentary floor leader, told Reuters. Postbank could fetch close to 3.6 billion euros ($3.9 billion) if it sells for a multiple of 0.8 times a book value of 4.5 billion euros, according to analysts’ calculations.
