Just In: Trump Raises Global Tariffs to 15% After Supreme Court Strikes Down Earlier Trade Measures. Read more

In a swift response to a major judicial setback, Donald Trump announced Saturday that he is increasing global tariffs from 10% to 15%, effective immediately.

The announcement was made on Truth Social, where the president framed the move as necessary to protect American industries and national interests.

The decision follows a ruling issued Friday by the Supreme Court that struck down Trump’s sweeping tariff policy, finding that the administration had exceeded its statutory authority in imposing broad trade levies without explicit congressional approval.

In his post, Trump characterized the Court’s decision as a temporary obstacle and asserted that his administration would pursue alternative legal mechanisms to maintain what he described as “strong, reciprocal trade enforcement.

” By raising the baseline tariff rate to 15%, the White House appears to be recalibrating its trade strategy while signaling it does not intend to retreat from aggressive economic measures.

The original tariff framework, which applied across a wide range of imported goods, had drawn criticism from business groups, trade partners, and several members of Congress.

Opponents argued that the measures increased consumer prices and strained diplomatic relationships, while supporters claimed they were necessary to counter unfair trade practices and revive domestic manufacturing.

Legal experts say the Court’s ruling could set a significant precedent regarding executive authority in trade policy.

The Constitution grants Congress the power to regulate commerce with foreign nations, though lawmakers have historically delegated portions of that authority to the executive branch.

The Court’s decision suggests limits to how broadly that delegated authority can be interpreted.

Global markets reacted cautiously to the announcement, with analysts warning of potential retaliatory measures from key trading partners.

Economists note that a 5-percentage-point increase in baseline tariffs could have wide-ranging implications for supply chains, import costs, and inflation.

Administration officials have not yet released detailed guidance on how the new 15% tariff rate will be implemented or whether exemptions will apply to certain countries or sectors.

Further legal challenges are widely expected as the policy takes effect.
