NEW YORK (AP) — The nation’s most influential banker, JPMorgan Chase CEO Jamie Dimon, told investors Monday that he continues to expect the U.S. economy to be resilient and grow this year. But he worries geopolitical events including the war in Ukraine and the Israel-Hamas war, as well as U.S. political polarization, might be creating an environment that “may very well be creating risks that could eclipse anything since World War II.”

The comments came in an annual shareholder letter from Dimon, who often uses the letter to weigh in broad topics like politics, regulation and global events and what it might mean to JPMorgan Chase, as well as the broader economy.

Dimon also used his letter to forcefully defend the firm’s diversity and equality efforts, pushing back on the arguments from Republicans who have said such efforts at Fortune 500 companies, colleges and universities are discriminatory and promote left-wing ideology.
