Deutsche Bank, Germany's largest lender, has been engulfed in crisis since the DoJ demanded up to $14 billion to settle claims that the bank missold U.S. mortgage-backed securities before the global financial crisis.

A DoJ spokeswoman declined to comment.

The DoJ is also looking into whether UBS Group AG mis-sold residential mortgage-backed securities.

Credit Suisse and Barclays are in mortgage-settlement talks with the DoJ, Bloomberg reported in September.
