12:21 PM EDT, 04/07/2026 (MT Newswires) -- US equity indexes fell while crude oil futures rose in midday trading on Tuesday after President Donald Trump reiterated his warning to Iran, exhorting them to reach a ceasefire deal before a deadline that expires later in the day.

The Nasdaq Composite fell 0.8% to 21,829.1, with the S&P 500 down 0.5% to 6,576.2 and the Dow Jones Industrial Average lower by 0.6% to 46,404.5.

Energy, Utilities, and Communication Services led gains, while Consumer Discretionary, Technology, and Materials were among the top decliners.

"A whole civilization will die tonight, never to be brought back again. I don't want that to happen, but it probably will," President Donald Trump said in a Truth Social post as his Tuesday 8 p.m. ET deadline on Iran to make a deal and open the Strait of Hormuz approaches. "Maybe something revolutionarily wonderful can happen, WHO KNOWS? We will find out tonight."

Iran cut off direct communications with the US over the threat, though talks with cease-fire mediators continue to reach a deal and reopen the Hormuz chokepoint, the Wall Street Journal reported.

West Texas Intermediate crude oil futures advanced 1.8% to $114.41, and Brent crude futures advanced 0.7% to $108.99.
