Trump introduced substantial tariffs on imports from countries including China, the European Union, Japan, Canada, and Mexico. These tariffs aimed to protect domestic industries and reduce trade deficits but led to significant market volatility. U.S. stock futures experienced sharp declines, with the Dow Jones futures dropping 3.4%, indicating a potential 1,300-point decrease at market open. The S&P 500 and Nasdaq futures also saw declines of 4% and 5%, respectively. Additionally, Bitcoin's price fell to $78,300, reflecting the broader market's reaction to these trade policies.
