Answer:
The most significant impact of the Great Depression on the rest of the world was the drastic decrease in world trade. The collapse of the American economy led to a sharp decline in the American market for European goods, and the U.S. Congress imposed high tariffs on imported goods. This protectionist policy was intended to keep American dollars in the United States and pay for American goods, but it backfired, as other nations responded by imposing their own higher tariffs. This caused world trade to drop by 65 percent, which contributed significantly to the economic downturn and led to high unemployment rates.
The decrease in world trade had a ripple effect, causing many countries that depended on exporting goods to the United States to suffer. Germany and Austria were particularly hard hit, given their war debts and dependence on American loans and investments. In Asia, both farmers and urban workers suffered as the value of exports fell by half between 1929 and 1931. Similarly, in Latin America, as European and U.S. demand for products such as sugar, beef, and copper dropped, prices collapsed.
Overall, the decrease in world trade had a significant impact on the global economy during the Great Depression, as it led to high unemployment rates, a decline in economic growth, and widespread economic hardship.
