The S&P 500 fell 19% after President Trump announced significant tariffs on April 2 but has since recovered slightly due to a 90-day pause on the most aggressive duties. Experts anticipate short-term volatility and uncertainty, with a 45% chance of recession within a year, while long-term consequences may include reduced economic growth and living standards. Analysts warn that these tariffs could represent a major policy mistake, leading to economic fragmentation and lasting harm, especially to the U.S. technology sector.
