Introduction
U.S. President Donald Trump has announced new 25% tariffs on all steel and aluminum imports, effective immediately. Additionally, he plans to introduce reciprocal tariffs on countries he deems to have unfair trade practices.
This move intensifies global trade tensions, especially as it follows the recent 10% duties on China and growing concerns about potential retaliatory measures from affected nations.

Key Announcements

25% tariffs on steel and aluminum imports will take effect Monday.
Reciprocal tariffs on select countries will be announced on Tuesday or Wednesday.
Canada, Brazil, Mexico, South Korea, and Vietnam are the biggest steel exporters to the U.S.
Canada is the top aluminum exporter to the U.S.

Market Reactions & Global Implications

Asian steel stocks declined after the announcement, with POSCO (NYSE:PKX) and Nippon Steel (TYO:5401) seeing notable drops.
China’s retaliation is expected, given recent U.S. tariff escalations.
U.S. metal producers may benefit, while manufacturers dependent on imported steel could see higher costs.

Looking Ahead: Economic Impact & Policy Shifts
Trump’s first-term tariffs had led to duty-free quotas for key allies. It remains to be seen whether Canada and Mexico will negotiate exemptions again or retaliate.
