From the story here:
Investment bank JPMorgan estimated in a report on Tuesday that Trump’s tariffs on China would have only modest effects on the broader U.S. economy. It based its analysis on a 12 percent average U.S. tariff on $450 billion of imports from China, estimating that this would add just 0.4 percentage points to U.S. consumer price inflation if the additional costs of the duties were passed on to consumers in their entirety.
