Oil prices ticked down and futures on the S&P 500 rose slightly on Sunday as investors reacted to continued uncertainty surrounding talks between the United States and Iran. President Trump said on Saturday that he was reviewing a peace proposal from Iran, but that he doubted it would be acceptable.
On Sunday evening, Mr. Trump signaled there could be some progress in moving ships out of the Strait of Hormuz, the vital oil trade route south of Iran. He wrote on social media that, beginning Monday morning, the United States would “use best efforts” to get ships out of the strait that were not involved in the conflict. Mr. Trump offered scant details about how the process would unfold.
