The United States doubled tariffs on steel and aluminium imports on Wednesday, activating a hike in the duties on the imported metals to 50% from the 25% rate introduced in March. The day also marks the Trump administration’s deadline for trading partners to submit their “best offers” to avoid further steep import duties set to take effect in early July.

New economic analyses, several conducted by the federal government using official data sources, point to slowing economic growth and increased consumer prices brought on by Trump’s trade war.
