Wells Fargo’s operational risk capital requirement soared almost 10% in 2018, while many of its peers posted reductions.

The San Francisco-based lender increased op risk-weighted assets (RWAs) to $328 billion from$300 billion at end-2017, which translates to a capital requirement of $26 billion. Op RWAs jumped$9 billion in the last three months of 2018 alone, reversing a slight drop recorded in the third quarter.
