Oil prices likewise seesawed between gains and losses amid continued uncertainty about what will happen in the war with Iran and how long it will slow the global flow of oil and natural gas. Iran on Monday rejected the latest ceasefire proposal and instead said it wants a permanent end to the war, though the talks may not have collapsed.
"We won't merely accept a ceasefire," Mojtaba Ferdousi Pour, head of the Iranian diplomatic mission in Cairo, told The Associated Press. "We only accept an end of the war with guarantees that we won't be attacked again."
Fighting is continuing, meanwhile, including an Israeli attack on an Iranian petrochemical plant. And in the background is the clock ticking toward a deadline, which Trump has moved multiple times, where he has threatened to attack Iran's infrastructure if it does not open the Strait of Hormuz. A fifth of the world's oil typically sails through the strait during peacetime.
"Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran," Trump said on his social media network over the weekend, threatening Iranian leaders that "you'll be living in Hell - JUST WATCH!"
Monday also offered the first chance for U.S. stock prices to react to a report from Friday that said U.S. employers hired more workers last month than economists expected. The unemployment rate unexpectedly improved.
