U.S. 10% tariff faces court test
Judges at the U.S. Court of International Trade are questioning whether the administration’s 10% global tariff can legally rest on a routine trade deficit, injecting fresh uncertainty into import costs and compliance rules for lenders and borrowers. Bloomberg also warns the tariff episode is nudging the expected global rate path higher, which raises the cost of capital assumptions behind many lending programmes. (reuters.com) (bloomberg.com)
A court in New York spent Friday asking a basic question with billion-dollar consequences: can a president put a 10% tax on almost everything the country imports just because the United States runs a trade deficit. The case is at the U.S. Court of International Trade, and the tariff has been in effect since February 24. (reuters.com) The administration switched to this tariff after the U.S. Supreme Court ruled on February 20, 2026 that the International Emergency Economic Powers Act does not let a president create tariffs by declaring an emergency. That ruling wiped out the broader tariff program the White House had been using since 2025. (congress.gov) (bloomberg.com) The replacement tool is Section 122 of the Trade Act of 1974. That law lets a president impose a temporary import surcharge of up to 15% for 150 days, but only to deal with what the statute calls “fundamental international payments problems,” not just any trade complaint. (whitehouse.gov) (law.cornell.edu) The White House set the new surcharge at 10%, not the 15% ceiling, and said it was needed because the United States has a persistent trade deficit and faces “nonreciprocal” treatment from trading partners. The proclamation says the measure lasts no more than 150 days unless Congress extends it. (whitehouse.gov) (federalregister.gov) The plaintiffs are 24 mostly Democratic-led states plus two small businesses. They told the court that a normal goods trade gap is not the same thing as the kind of balance-of-payments crisis Congress had in mind in 1974, so the president cannot use Section 122 as a shortcut around Congress. (reuters.com) (politico.com) Judges pressed government lawyers on that exact point during oral argument on April 10. Reuters reported that the panel challenged whether a large trade deficit by itself is enough legal basis for a broad tariff that hits most imports from most countries. (reuters.com) That sounds technical, but the bill shows up in ordinary places. A 10% tariff works like a new tollbooth at the border, so importers have to guess whether to raise prices, absorb the hit, or rewrite contracts that were priced before February 24. (reuters.com) (federalregister.gov) Banks and nonbank lenders get pulled in because trade finance, inventory loans, and working-capital lines are built on assumptions about landed cost. If the legal basis for the tariff is shaky, the borrower’s cost base and the lender’s collateral math can change in the middle of a loan. (reuters.com) Bloomberg says the tariff shock is also pushing the expected global interest-rate path higher. The logic is simple: if tariffs lift import prices, central banks worry more about inflation, and higher expected policy rates feed straight into the discount rates used to price loans, projects, and leveraged deals. (bloomberg.com) That is why this case is bigger than one courtroom fight over one trade statute. If the judges strike the tariff down, importers may get relief from a border tax that began on February 24; if they uphold it, the White House keeps a fast 150-day tariff tool that Congress wrote half a century ago for a much narrower problem.
