That progress came too slowly for Buffett. His pullback from the bank started in 2017, a year after the scandals began erupting, and then accelerated during the pandemic. The reduction probably reflects Berkshire rethinking its bank exposure amid Covid-19’s fallout, and a shift toward Bank of America, in part because of frustration with the pace of Wells Fargo’s cleanup, said David Kass, a professor of finance at the University of Maryland’s Robert H. Smith School of Business.
Buffett has “very high ethical standards” when it comes to stock picks, Kass said.
Buffett has hinted at other considerations as well. When Wells Fargo was seeking a new CEO in 2019, he warned the lender not to pick someone from Wall Street. Its board chose Scharf, who previously ran Bank of New York Mellon Corp. and was a former lieutenant to Jamie Dimon at JPMorgan Chase & Co. Charlie Munger, Buffett’s longtime business partner and a Berkshire vice chairman, later criticized Scharf for planning to run the San Francisco-based bank from New York.
