Jamie Dimon, CEO of JPMorganChase, the United States' largest bank, has a financial stake in almost everything. Unlike many CEOs, he says it’s his job to speak out on many things.This week, Dimon released his annual letter to shareholders — a document that comments on banking issues and also assesses risks to the economy, from inflation to the war in Iran. The letter asserts his company is ready for anything, noting, among other things, that it has profited during economic booms and also during recessions. In this episode of NPR’s Newsmakers, Dimon tells host Steve Inskeep that he doesn’t worry much about the way President Trump’s contradictory statements tend to send financial markets sliding and soaring again, saying, “I have to deal with the world I got.” NPR's Newsmakers is where you'll find NPR's biggest interviews.
