Liberation Day Tariffs Use a Crude Formula to Reshape Global Trade

Trump announced a universal 10 percent tariff along with substantially higher country-specific tariff rates, calculated largely from countries' bilateral trade deficits with the United States rather than from those countries' actual tariff schedules on U.S. goods.

The announcement triggered sharp market declines and led companies to delay investment decisions amid the uncertainty. Economists and trade specialists criticized both the legal authority cited for the tariffs and the methodology used, arguing that a formula based on trade deficits mischaracterized what the administration described as reciprocal foreign trade barriers.

A U.S. trade court later blocked the Liberation Day tariffs, indicating a judicial body found grounds to halt their implementation.
