Federal Reserve's Williams: Trump's tariffs could push inflation up to 4%.

The Federal Reserve's Williams has warned that Trump's tariffs will cause US inflation to soar to as high as 4% this year and push up unemployment and hit economic growth amid "pervasive" uncertainty. He also said he expects economic growth to "slow significantly from last year, probably just under 1%", while unemployment could rise to 4.5% -5% from the current 4.2%. Williams' gloomy assessment comes as the US financial marekt has been hit over the past week by Trump's announcement of extremely protectionist trade policies, which he has only partially rolled back.
