US President Donald Trump revealed details of new tariffs targeting various sectors and countries, with reciprocal customs duties set to take effect. The move seeks to stimulate American jobs and businesses, but experts warn potential market volatility and long-term economic impacts are yet to be fully understood. This follows a history of similar trade actions against China, Canada, and Mexico, with an additional 25% tariff on automobile imports. Stocks showed mixed reactions, with the S&P 500 experiencing fluctuations throughout the day. Despite gains briefly reaching highs of over 1%, analysts caution that this may only be a temporary relief, predicting lasting negative effects on both growth and inflation.
