Donald Trump will trigger a “period of chaos” and sharp price rises if he scraps Joe Biden’s manufacturing tax credits and increases tariffs as planned, the White House’s top economic adviser said.

Lael Brainard, director of the National Economic Council, told the Financial Times that Trump’s plan to gut the Inflation Reduction Act and the Chips and Science Act — President Biden’s signature legislation — would harm US manufacturing capacity.

“What would be very disruptive is if you saw sweeping across-the-board tariffs,” Brainard said in an interview. “We want to strengthen our manufacturers through [the] protection of the credits in the historic investment laws enacted by this administration and not throw us back into a period of chaos and price increases.”
