Trump to raise global tariff from 10% to 15%… “To take effect within months”

U.S. President Donald Trump, strongly pushing back against a Supreme Court ruling that put the brakes on a key plank of his trade agenda, announced he would immediately raise a universal tariff applied worldwide from 10% to 15%.

On the 21st (local time), Trump said on his social media account, “I thoroughly and in detail reviewed the absurd, poorly written, and extremely anti-American tariff ruling handed down by the Supreme Court yesterday,” adding, “As President of the United States, I state through this statement that I will raise tariffs with immediate effect.”

He stressed, “I will immediately lift the 10% universal tariff imposed on various countries that exploited the United States for decades without any penalty before I came along, to 15%—the highest level that is fully legally permitted and verified.”

He added, “The Trump administration will determine and announce new, legally permissible tariffs within the next few months,” saying this “will carry forward our tremendously successful process of making America great again to an even greater extent than ever before.”

Earlier, the U.S. Supreme Court ruled that Trump’s reciprocal tariff policy was unlawful. Some in the market had viewed the decision as easing trade uncertainty.

However, immediately after the ruling, Trump signed an executive order imposing a 10% global tariff worldwide, citing Section 122 of the Trade Act. With his announcement that the rate will be raised to 15%, additional executive measures are expected to follow.

Section 122 of the Trade Act allows the president, in response to economic emergencies such as a deteriorating balance of payments, to impose tariffs of up to 15% for up to 150 days. To keep the measures in place beyond 150 days, however, congressional approval is required.

The move is expected to intensify tensions between the administration and the judiciary, while also reigniting uncertainty in the global trade environment.
