JPMorgan Chase CEO Jamie Dimon sees an end on the horizon. But not yet.

The elegant, amenity-filled interior of the Norman Foster-designed 1,388-foot tower belies the real work still to be done; Dimon’s remit has arguably never been more challenging. It isn’t just war in the Middle East, or that the Trump administration poses unprecedented uncertainty, or that the bank faces a raft of new competitors in payments, crypto, private equity and credit, and fintech. And it isn’t just that many of JPMorgan’s competitors, even Citigroup and Wells Fargo, are in good shape, too, or that artificial intelligence could reorder the bank’s business, or that risk from exposure to private-credit loans could worsen. It isn’t even that, yes, Dimon needs to name a successor at some point.
