The Consumer Financial Protection Bureau may fine Wells Fargo WFC, -1.62% several hundred million dollars and as much as $1 billion for auto insurance and mortgage lending abuses, Reuters reported, citing sources with knowledge of the plans. The fine would be the first since Mick Mulvaney was named interim director of the CFPB. Mulvaney is eyeing a penalty that would dwarf the $100 million the CFPB fined Wells Fargo in September 2016 to settle its phony accounts scandal, the report said.
