President Trump announced the increase of global tariffs to 15% after the Supreme Court declared his previous tariffs illegal.

President Donald Trump announced that he will raise global tariffs to 15%, from 10%, "effectively immediately", after a decision by the Supreme Court which found that his tariffs imposed under the International Emergency Economic Powers Act were applied illegally. In a post on Truth Social, Trump expressed disappointment at the Court's decision, which was voted 6-3, and criticized the Republican judges who did not support him. He announced that he will use the Trade Act of 1974 to continue his tariff policy, although this limits tariffs to 15% and has a maximum duration of 150 days. Trump praised the judges who supported him, calling Brett Kavanaugh his "hero". The Court's decision underscored the need for clear authorization from Congress to impose tariffs.
