How did the Hawley smoot traff help spread the depression overseas?

The Hawley-Smoot Tariff, enacted in 1930, significantly raised U.S. tariffs on imported goods, prompting other countries to retaliate with their own tariffs. This led to a decline in international trade, worsening the global economic downturn. As countries struggled to export their goods, economic conditions deteriorated worldwide, contributing to the spread of the Great Depression beyond the United States. The resulting trade barriers further isolated economies, exacerbating the financial crisis on a global scale.
