The commercial side of DB is rock solid. They are considered a powerhouse corporate lender, deeply embedded within the German economy. On the whole (compared to other highly advanced economies), Germany companies prefer to borrow money from corporate banks directly, instead of issue bonds. (The aversion to capital markets in Germany is bizarre to me.) And corporate borrowers prefer a national champion, rather than a foreign competitor. (Massive lending [infra, etc.] that requires syndicates of commercial banks are another story.)
On the other hand, the investment bank side of DB... Sigh, that is another story. Wildly incompetent management. (See also: Credit Suisse) I cannot believe that the regulator or Bundestag (Parliment) did not force them to spin out the IB. If the corporate bank sinks with the IB, it would cause serious economic damage in Germany.
