In February 2026, the United States Supreme Court struck down the import tariffs imposed by the Trump administration in April 2025 under the International Emergency Economic Powers Act (IEEPA), eliminating the import charges that had been applied to specific countries but leaving in place those imposed on certain products. While the White House is now working to replace those tariffs to ensure that countries follow through on the trade deal commitments they made over the last year, the time that these tariffs have been in place has helped shed light on their overall impact.
In 2025, we wrote a report called “The Tariff Trilemma,” in which we focused on three types of tariffs — reciprocal, revenue, and restrictive — and their respective trade-offs and purposes. Now that these tariffs have been in place for over a year, we have actual data to assess how the administration’s trade policies have affected the economy and what they may mean going forward, even after the Supreme Court ruled the IEEPA tariffs unconstitutional.
This report briefly reviews the three different types of tariffs and what sets them apart. We then focus on how these tariffs have changed trade flows, investment spending, and domestic inflation. We also discuss the impact of trade on financial markets, including domestic and international equity markets, global currencies, and interest rates.
