How the U.S. has used tariffs through history — and why Trump is different, economists say

Key Points

  • President Trump imposed broad tariffs on China, with threats of tariffs on other major trading partners like Canada, the EU, and Mexico.
  • Historically, the U.S. has used tariffs for revenue, restriction of imports, and reciprocity in trade negotiations.

Summary

President Donald Trump's recent imposition of tariffs on China, alongside threats of similar actions against Canada, the EU, and Mexico, has sparked discussions on the historical use of tariffs in the U.S. Since the nation's founding, tariffs have served multiple purposes, encapsulated by what Douglas Irwin, an economics professor, calls the "three Rs": revenue, restriction, and reciprocity. Initially, tariffs were crucial for federal revenue, funding up to 90% of government operations until the Civil War. Post-war, the U.S. diversified its revenue sources, reducing reliance on tariffs. However, tariffs continued to be used to protect domestic industries from foreign competition, notably through acts like the Smoot-Hawley Tariff of 1930. The post-World War II era saw a shift towards using tariffs as bargaining tools in international trade agreements, promoting lower tariffs globally. Trump's approach, however, is described as unusual due to its broad application and the linking of trade policy with issues like the U.S. drug crisis, marking a significant departure from recent presidential norms.
