Trump Raises Global Tariff To 15%, Calling Supreme Court Ruling 'Anti-American'

US President Donald Trump announced an immediate increase of the proposed global tariff rate from 10% to 15%, citing a recent "ridiculous, poorly written, and extraordinarily anti-American decision" by the US Supreme Court. The Supreme Court had ruled 6-3 that his administration lacked the legal authority to impose sweeping global duties under the International Emergency Economic Powers Act (IEEPA).

Key points

• The new 15% global tariff is being imposed under Section 122 of US trade law (balance-of-payments tariff), which allows tariffs up to 15% for up to 150 days.
• Trump accused several countries of exploiting the US for decades and claimed the revised rate is legally sound.
• The Supreme Court setback involved ruling that IEEPA does not authorize the president to unilaterally levy broad, economy-wide tariffs.
• Justices Clarence Thomas, Samuel Alito, and Brett Kavanaugh dissented from the Supreme Court ruling.

Why it matters

This action represents a significant escalation in trade policy following a major judicial check on presidential authority, likely increasing economic uncertainty.
