U.S. stock index futures fell on Monday as tariff uncertainty spooked investors anew after President Donald Trump announced new 15% tariffs despite a Supreme Court ruling canceling widespread taxes.
In a 6-3 decision Friday, the Supreme Court struck down most of the tariffs President Trump imposed last year, ruling that the emergency law he relied on did not authorize the imposition of the tariffs.
Using separate legislation, President Trump announced a global tax, first at 10% and then at 15%, that could last for five months while his administration looks for a more permanent workaround.
“When you’re in a company and you don’t even know what your suppliers are going to be or what your supply chain is going to be or what the tariffs are going to be, it’s very difficult from a business standpoint to know how to plan,” said Arthur Laffer Jr., president of Laffer Tengler Investments.
“This is a major concern for American businesses, and that’s why it’s so important that we resolve this issue as soon as possible so that businesses know what the playing field actually is and can plan accordingly.”
All three major stock indexes posted weekly gains on Friday, as the market accepted the Supreme Court’s decision, and the Nasdaq ended its five-week losing streak.
At 5:22 a.m. ET, the Dow E-mini was down 125 points, or 0.25%, the S&P 500 E-mini was down 15.5 points, or 0.22%, and the Nasdaq 100 E-mini was down 91 points, or 0.36%.
