US stock market futures plummeted on Wednesday. The Dow Jones futures dropped by 1.9%, with S&P 500 and Nasdaq futures falling over 2%. This sharp dip is driven by growing investor fears as the yield on US Treasury securities surged to 4.4% overnight, briefly surpassing 5% for the 30-year bond. The rise in yields signals stress within the bond market. The new tariffs imposed by President Trump on goods from Europe, Japan, Vietnam, and China are significantly impacting trade. These actions have increased overall taxes, pushing Chinese products to face over 100% in total tariffs due to multiple increases and retaliations. This escalating trade tension could severely impact economic ties between the two countries.
