On February 10, 2025, President Trump formally announced a 25% tariff on all steel and aluminum imports, revitalizing international trade tensions. Amid existing 10% tariffs on China, these new tariffs are aimed not only at strengthening domestic manufacturing but also at unifying U.S. tax levels with those of other nations. Experts warn of rising inflation and retaliatory trade barriers, particularly from the EU, which has already indicated a preparedness to respond. Shares in U.S. steel companies surged, while businesses reliant on these materials, such as auto manufacturers, faced declining stock prices.
