The Smoot-Hawley Tariff Act of 1930, intended to protect American farmers and industries from foreign competition, dramatically increased tariffs on thousands of imported goods. A significant consequence was retaliatory tariffs imposed by other nations, notably Canada and European countries. These nations increased duties on American exports, effectively closing off foreign markets to American goods and exacerbating the global economic downturn of the Great Depression.
This retaliatory action reduced international trade substantially, contributing to a global decline in production and consumption. The decreased trade volume further deepened the economic woes of the period, highlighting the interconnectedness of global economies and the dangers of protectionist trade policies. The Smoot-Hawley Tariff serves as a historical example of the negative consequences of escalating trade barriers.
