Deutsche Post may wait until next year to sell Deutsche Postbank, the German retail bank, as bankers caution against further deals this year after Commerzbank agreed on Sunday to buy Dresdner Bank from Allianz for €9.8bn ($14.2bn).

There had been strong indications since the beginning of the summer that Deutsche Post was planning to carry out a sale of Postbank, although there has been little movement in recent weeks.
