Kiel Institute Study Finds Americans Bear 96% of Tariff Costs

A study by the Kiel Institute for the World Economy concluded that 96% of the cost of import tariffs imposed by President Donald Trump is borne by American importers and consumers. Analyzing 25 million shipment records worth approximately $4 trillion, researchers found that foreign firms shouldered only 4% of the burden, as they reduced export volumes rather than lowering prices. The report characterizes the $200 billion surge in customs revenue as a consumption tax on Americans, contradicting administration claims that foreign entities pay the levies.

Despite these findings, Donald Trump has expanded his tariff strategy. He announced a 25% import duty on goods from India, citing India's continued purchase of Russian oil and defense equipment. He also instituted a 10% import tax on eight European countries starting in February, citing their opposition to U.S. control of Greenland, with threats of 25% duties in June if Denmark transfers the territory.

Critics, including Bloomberg News Editor-in-Chief Emeritus Matt Winkler, have described the tariffs as punitive and counterproductive. Winkler noted that India experienced its largest five-month export decline since 1960 between April and August 2025. While the administration suggested tariffs would significantly reduce the national deficit or fund citizen checks, the $200 billion generated remains minor compared to a 2025 deficit of $1.7 trillion and a national debt exceeding $38 trillion. The Supreme Court of the United States is expected to rule on the legality of several tariffs instituted under emergency national security laws.
