According to Reuters, Wells Fargo reported a 62% increase in problem loans primarily due to weakness of oil and gas companies.

Reuters reported Wells Fargo’s loans that regulators would classify as “criticized” increased to almost $30 million as of March 31, up from $18.5 billion at the same time last year.

Reuters said that Wells Fargo’s total exposure in the energy-related sector fell to $43.5 billion in Q1/16, a drop of $317 million.
