JPMorgan CEO Dimon goes after Clinton for attacking 'a whole class of people'

Cooler heads should prevail: Dimon on WFC

Jamie Dimon came to the defense of his fellow bankers on Monday, and went after Hillary Clinton while he was at it.

JPMorgan Chase's chief executive pushed back at the Democratic presidential candidate after she criticized the U.S. banking culture amid Wells Fargo's fake account scandal. "It is outrageous that eight years after a cowboy culture on Wall Street wrecked our economy we are still seeing powerful bankers playing fast and loose with the law," Clinton said on Monday.

In response, Dimon said: "When people blanket a whole class of people...that's just unfair."

Wells Fargo opened credit card, checking and savings account without customers' permission and fired thousands of employees over the course of several years for the deceptive sales practices, without fixing the problem.

Banks have been under a microscope both in the U.S. and abroad. Concerns are enduring about Deutsche Bank, which faces an expected multi-billion dollar fine from the U.S. government for activities prior to the mortgage crisis. Financial markets across the globe were sent into flux last week, amid reports of hedge funds reducing their exposure to Deutsche Bank as well as talks of a possible settlement.

Still, amid market worries that Deutsche is facing a capital squeeze, Dimon said he believes the German lender is going to be fine.

"There is no reason that Deutsche Bank shouldn't get over its problems," the head of the largest U.S. bank by assets said of the fourth-largest European bank by assets.

Deutsche shares have gotten pounded as investors worry that it has a weak capital position that is in even more danger due to a looming settlement with the U.S. Department of Justice involving the firm's mortgage-backed securities operations. The banks American Depositary Receipts are down about 47 percent in 2016 and nearly 53 percent over the past 12 months.

"They have plenty of capital, plenty of liquidity," Dimon said during an telephone interview on CNBC's "Power Lunch." "We want all these banks to get through because it's better for everybody."

Shares of Germany's largest bank ended Monday trading near $13, a decline of less than 1 percent. Wells Fargo shares fell 1.02 percent.
