President Donald Trump announced plans to raise the U.S. global tariff rate to 15 percent on all imports after the U.S. Supreme Court invalidated key parts of his earlier tariff program this week, forcing the government to refund billions of dollars in duties already collected.

The Supreme Court ruled that Trump exceeded his authority by imposing broad tariffs on imports without clear approval from Congress, saying that such sweeping action must be authorized. This decision means that the government will have to return significant amounts of money to companies that have already paid the invalid tariffs, a refund process that will cost American taxpayers billions.

In response, Trump said he plans to implement a temporary global tariff of 15 percent instead of the current 10 percent, which is the maximum level allowed within his authority, in an effort to maintain leverage and protect U.S. industries. He called the Supreme Court’s ruling “unjust” and framed the move as a way to continue pushing back against what he says is unfair trade.

Trade experts say a 15 percent tariff applied across a wide range of products will lead to even higher prices on imported goods for American consumers and will cause retaliation from trading partners. By raising the rate, Trump is hoping to signal that his trade policy will continue despite the setback.
