In a significant move, President Trump has announced plans to double tariffs on imported steel and aluminum to 50%, prompting a surge in U.S. steelmaker stocks while drawing sharp criticism from international leaders and market analysts. The announcement has raised U.S. aluminum and steel prices sharply, causing concerns about potential impacts on consumer goods and job cuts, particularly in Canada and the EU. Financial markets have reacted with mixed signals; some stocks have jumped, particularly those related to steel production, while concerns loom over broader market stability. Experts warn that the tariff hike could complicate trade relationships and impact housing market costs as Trump attempts to position the U.S. as a leading steel producer once again.
