Germany's largest lender said about two weeks ago it would fight a $14 billion (£10.80 billion) demand from the U.S. Department of Justice to settle claims it missold the securities.

An agreement could be announced in the next couple of days, a person familiar with the matter told AFP.

The final amount of the settlement could be slightly different, the source said. (http://yhoo.it/2dfHX74)

Deutsche Bank and DoJ officials declined to comment.

The bank's U.S.-listed shares were up 13.4 percent at $13.02 in heavy midday trading. The stock rose as much as 15.16 percent, its best intraday percentage gain in nearly five years.

Deutsche Bank's Frankfurt-listed shares closed 6.4 percent higher at 11.57 euros after the AFP story emerged.
