Jamie Dimon’s not-so-subtle warning for Bernie Sanders

Jamie Dimon waved a placard at Bernie Sanders in his annual shareholders letter on Wednesday.

It says, in effect: “Don’t Bite the Hand That Feeds Us.

With the Democratic presidential primary battle coming to New York on April 19, including firebrand Sanders who frequently bashes Wall Street, the JPMorgan Chase chief executive sang a different tune in the letter.

Dimon argued that big banks such as JP Morgan, with structures that span corporate and investment banking, perform “mission-critical services . . . that regional and community banks simply cannot do.”

He also noted that attempts to undermine big banks could threaten US global leadership in financial services.

In addition, he raised the alarm about lower levels of liquidity, saying they have “gotten worse.”
