Ackermann is bullish now, but in March he was on his knees

Horst Köhler, German president, heated up the debate over the credit crisis last week by attacking financial markets as a monster. The markets’ unacknowledged champion, Deutsche Bank CEO Josef Ackermann, hit back a few days later, saying the crisis would soon be over and banks should not be demonised. Much of what he said may be right, but it would be more persuasive if he had not led calls for the public sector to bail out the financial markets.
