Jamie Dimon trades jabs with banker he called a 'jerk'

Jamie Dimon

Independent Community Bankers of America President Camden Fine and the JPMorgan Chase CEO trade blame for "bank-on-bank violence."

Not everyone in banking is intimidated by Jamie Dimon , it turns out.

Camden Fine, president and CEO of the Independent Community Bankers of America, a trade organization for thousands of smaller banks, hit back after being called a "jerk" Wednesday morning on CNBC .

[Programming note: Camden Fine is slated to appear on "Squawk Box" at 6:30 a.m., ET, Thursday.]

During his appearance on CNBC, an anchor read a statement from Fine regarding a column Dimon, CEO of JPMorgan Chase , wrote in April in The Wall Street Journal calling for large and small banks to come together. Fine ridiculed the column, saying in a statement that Dimon was trying to deflect intensified regulatory pressure on big banks.

"I think the guy who wrote that's a jerk, OK." Dimon said.

"We are one of the biggest banks to community banks," Dimon said Wednesday morning. "I'm completely sympathetic to the community bank saying that 'some of these regulations are killing us' ... I agree with that."

Dimon's "remarks reflect Wall Street's inability to take responsibility for the economic crisis it caused and the taxpayer-funded guarantee against failure it continues to enjoy," Fine said in a statement provided to CNBC.com after Dimon's appearance. "The nation's financial and economic stability should not be at the mercy of a few large financial institutions, regardless of whether they process checks for other banks."

For his part, Dimon went on to say that he wants regulatory burdens for community banks reduced, even if the pressure isn't eased on bigger banks — like his.

But it's probably too little, too late for JPMorgan or Dimon to get any sympathy from Fine.

"ICBA engages not in 'bank-on-bank violence,' which seems to be the new mantra of the too-big-to-fail banks and their hired-gun trade representatives," Fine said in his statement, repeating a term Dimon used during the interview. "Rather, we are in the pursuit of a level playing field for banks and financial services providers of all sizes."

JPMorgan declined to comment further after being provided a copy of Fine's statement.
