Silicon Valley Bank's collapse , as well as the closure of crypto-focused Signature Bank and Silvergate Capital, all in March, "takes us further away from risks being idiosyncratic," analyst Betsy Graseck wrote in a note Monday.
The end result is lower net interest margins, net interest income and return on equity across the industry, Graseck wrote.
Among the large-cap banks, JPMorgan Chase , Wells Fargo and Regions Financial are buys, she said.
Wells Fargo sank 8.7% and Regions Financial tumbled 11.8%, while American Express lost 5.5% over the same period.
Of that total, JPM and Wells Fargo contributed $5 billion each.
