Wall Street set to open lower as oil, banks weigh

Wall Street was set to open lower on Friday, in tandem with oil prices, and as financial stocks came under pressure in the wake of a massive $14 billion fine slapped on Deutsche Bank. The far bigger-than-expected fine was levied by the U.S. Department of Justice to settle claims that the German bank missold mortgage-backed securities. Deutsche Bank's U.S.-listed shares were down 8.5 percent in premarket trading.
