In July 2015, Wells Fargo became the world's largest bank by market capitalization, edging past ICBC, before slipping behind JPMorgan Chase in September 2016, in the wake of a scandal involving the creation of over 2 million fake bank accounts and illegal manipulation of other accounts by Wells Fargo employees.
