Chairman and CEO, JPMorgan Chase
Jamie Dimon runs the largest bank in the United States and is the longest-serving CEO of a major American bank. He is the only bank leader still in post who lived through the 2008 credit crisis from the corner office. His annual shareholder letter is read well beyond the financial sector as an economic essay, and his quarterly commentary is treated as an early indicator of US consumer health and the credit climate.
JPMorgan sees the payments, credit cards and corporate loans of a large share of the US economy. When Dimon comments on consumer spending or defaults, he is speaking from data that runs months ahead of official statistics.
