Wild Trading Day at Deutsche Bank Raises Questions on Risk

U.S. regulators have spent much of the past decade trying to get a better handle on beleaguered Deutsche Bank AG. Traders at the German lender’s U.S. unit suffered a one-day loss in the first quarter that was 12 times what internal risk officers estimated for regulatory purposes it might lose on a typical day, according to a previously unreported May filing. Deutsche Bank’s U.S. trading loss was offset by related gains in London, according to people with knowledge of the bank’s operations.
