JPMorgan CEO Jamie Dimon has warned that there's a 50-percent chance of the U.S. slipping into a recession, pointing to President Donald Trump's tariff policies as a key driver of inflation and economic slowdown. Dimon praised the recent U.S.-UK trade deal for calming markets but noted ongoing uncertainty with China. He called for dialing back aggressive policies through dialogue, adding that it's too early to predict the severity of any potential recession.
