President Trump Raises Global Tariff To 15% After Reviewing Supreme Court Ruling

President Trump announced Saturday that he is increasing his newly imposed worldwide tariff from 10 percent to 15 percent following what he described as a complete review of the Supreme Court’s decision blocking his earlier reciprocal tariffs.

In a Truth Social post, President Trump said the Court’s ruling was poorly written and anti American, and declared that he would immediately raise the tariff to what he called the fully allowed and legally tested 15 percent level. The increase takes effect immediately under the authority he is invoking.

The White House previously clarified that the administration is acting under Section 122 of the Trade Act of 1974. That provision allows the president to address certain fundamental international payment problems through temporary import surcharges and other trade restrictions. The initial proclamation imposed a 10 percent ad valorem duty on most imported goods for 150 days, beginning February 24.

According to a White House fact sheet, the purpose of the tariff is to stem the outflow of U.S. dollars to foreign producers, encourage domestic manufacturing, and correct the nation’s balance of payments deficit. Officials argue that strengthening domestic production will create good paying jobs and help stabilize the economy.

The tariff hike comes one day after the Supreme Court ruled 6 to 3 that President Trump exceeded his authority under the International Emergency Economic Powers Act when he imposed broad reciprocal tariffs on dozens of countries. The Court held that the 1977 statute does not authorize the president to levy sweeping tariffs.

President Trump sharply criticized the justices who ruled against him and said he was ashamed of their decision. At the same time, he praised Justices Clarence Thomas, Samuel Alito, and Brett Kavanaugh for their dissenting opinions, calling them strong defenders of the country.

The administration has indicated that additional legally permissible tariff actions could follow in the coming months as it continues its effort to reshape international trade and prioritize American manufacturing and national economic security.
