#TradeWarEases Trade war eras refer to periods of economic conflict between nations where countries impose tariffs or other trade barriers on each other to protect domestic industries. One notable era was during the 1930s Great Depression, marked by the U.S. Smoot-Hawley Tariff Act, which worsened global economic conditions. In recent history, the U.S.-China trade war (2018–2020) is a key example, involving tariffs on billions of dollars' worth of goods. Trade wars can disrupt global supply chains, increase consumer prices, and create economic uncertainty. They often arise from disputes over trade imbalances, intellectual property rights, or national security concerns in international commerce.
