The US Supreme Court’s decision striking down tariffs imposed by President Donald Trump has done little to ease pressures on the global economy, with analysts warning that uncertainty over future trade policy may instead intensify. Economists said the ruling, while limiting Trump’s use of tariffs under emergency powers, is unlikely to change the broader trajectory of global trade tensions as Washington explores alternative ways to impose duties, reported Reuters.
“In general, I think it will just bring in a new period of high uncertainty in world trade, as everybody tries to figure out what the U.S. tariff policy will be going forward,” said Varg Folkman, analyst at the European Policy Centre think tank. “In the end it’s going to look pretty much the same.”Following the judgment, Trump announced new global tariffs of 10 per cent for an initial 150-day period and acknowledged uncertainty over whether funds collected under the annulled levies would be refunded.Analysts said multiple questions remain unresolved, including what new tariffs could emerge and whether countries that negotiated agreements with the US to soften tariff impacts may reopen those arrangements.Economists at ING bank said, as quoted Reuters, the ruling does not mark an end to tariff-driven trade policy. “The scaffolding has come down, but the building remains under construction. No matter how today’s ruling reads, tariffs are here to stay.”The court’s decision applies only to tariffs introduced under the International Emergency Economic Powers Act (IEEPA), legislation designed for national emergencies. Those levies are estimated to have generated more than $175 billion in revenue.According to Global Trade Alert, the ruling reduces the trade-weighted average US tariff rate from 15.4 per cent to 8.3 per cent. Countries facing higher tariffs — including China, Brazil and India — could see double-digit percentage-point reductions, though duties remain elevated.Countries that struck bilateral deals with Washington to mitigate tariff impacts are now expected to assess whether the ruling offers grounds to renegotiate terms.Bernd Lange, chair of the European Parliament’s trade committee, said lawmakers would evaluate the implications while moving toward ratification of the EU-US trade pact.“The era of unlimited, arbitrary tariffs … might now be coming to an end,” Lange said on X. “We must now carefully evaluate the ruling and its consequences.”Britain, meanwhile, said it expects its preferential trading arrangement with the United States — including a baseline 10 per cent tariff — to remain unchanged.Despite years of tariff disruptions, the global economy has broadly held up. A Federal Reserve Bank of New York report indicated that much of the tariff burden has been absorbed by US consumers.The International Monetary Fund projected global growth at a “resilient” 3.3 per cent in 2026 in its latest World Economic Outlook update.China reported a record trade surplus of nearly $1.2 trillion in 2025, supported by stronger exports to markets outside the United States as producers adapted to tariff pressures.Some countries may therefore opt to retain existing bilateral deals rather than risk renewed instability, Folkman said, referring to the uncertainty triggered by Trump’s “reciprocal” tariffs in 2025.However, Niclas Poitiers, research fellow at economic think tank Bruegel, told Reuters political uncertainties surrounding the EU-US trade agreement remain significant.“There could be circumstances in which the deal unravels,” he noted.
