A new Harvard study reveals that the U.S. tariffs imposed on April 10th have triggered broad-based price hikes across the retail sector, according to Benzinga. Researchers tracked over 330,000 daily prices at four major retailers and found that prices of Chinese imports spike following the 125% tariff. U.S.-made goods also rose in price due to reliance on imported inputs like packaging and components. The study notes that price increases began before the tariffs took effect, as retailers braced for demand shifts and cost pressures. U.S. manufacturing contracted for the second consecutive month in April, according to early May data from the Institute for Supply Management.
