President Donald Trump announced that he will raise the existing 10% global tariff to 15% to make up for a Supreme Court ruling that blocked other tariffs one day after the decision was issued.

Trump lambasted the high court in a Truth Social post on Saturday morning, calling the decision “ridiculous, poorly written, and extraordinarily anti-American.”

“Please let this statement serve to represent that I, as President of the United States of America, will be, effective immediately, raising the 10% Worldwide Tariff on Countries, many of which have been “ripping” the U.S. off for decades, without retribution (until I came along!), to the fully allowed, and legally tested, 15% level,” the president asserted.

“During the next short number of months, the Trump Administration will determine and issue the new and legally permissible Tariffs, which will continue our extraordinarily successful process of Making America Great Again,” he explained. “GREATER THAN EVER BEFORE!!!” 

The court ruled in a 6-3 vote on Friday to reject the president’s authority to issue tariffs under the International Emergency Economic Powers Act, a decision seen as a major test of the executive branch’s power concerning trade.

Trump made several posts in the hours after the decision came down on Friday evening, expressing his disappointment in the court.

“Those members of the Supreme Court who voted against our very acceptable and proper method of TARIFFS should be ashamed of themselves. Their decision was ridiculous but, now the adjustment process begins, and we will do everything possible to take in even more money than we were taking in before!” he wrote, hinting at his tariff increase, which came mere hours later. 

Tariffs have been central to Trump’s economic strategy in his second presidential term, as the president tries to clean up after the affordability crisis and record-high inflation Americans faced during the Biden administration. Trump has argued that his tariffs decrease trade deficits and protect American workers from foreign countries that have been taking advantage of the U.S. for decades.

He has cited Section 122 of the Trade Act of 1974 for enabling the 10% — soon to be 15% — tariffs he currently imposes, though he plans to explore other legal pathways.
