The US stock market opened lower as oil prices surged and Treasury yields climbed sharply, triggered by recent comments from former President Trump rejecting an Iran peace proposal. This has rekindled fears of escalating US-Iran tensions, contributing to a dip in major indexes, including the Dow Jones, S&P 500, and Nasdaq. Investors expressed concern over inflation as bond yields reached new heights, exacerbating market unease. Oil prices have rebounded, further dragging down US futures as the market adjusts to these geopolitical developments and their potential economic repercussions.
