World shares are mixed, with markets in Greater China closed for holidays. U.S. futures declined as optimism over the U.S.-Iran deal to end their war was dimmed by the postponement of high-stakes talks on reopening negotiations over Iran’s nuclear program and getting oil moving through the Strait of Hormuz. Sentiment has also been hit by expectations that central banks including the Federal Reserve will keep raising interest rates to try to curb inflation. On Thursday, the S&P 500 rose 1.1% and the Dow industrials added 0.1%. The Nasdaq composite jumped 1.9%. U.S. markets will be closed Friday for Juneteenth.
