03:52 PM EDT, 04/07/2026 (MT Newswires) -- US equity indexes traded moderately lower while crude oil futures were mixed ahead of Tuesday's close as investors weighed the likelihood of a ceasefire deal with Iran before a deadline at 8 p.m. ET.

The Nasdaq Composite fell 0.4% to 21,894.1, with the S&P 500 down 0.3% to 6,589.2 and the Dow Jones Industrial Average lower by 0.5% to 46,461.3. Most sectors fell, with consumer discretionary and consumer staples leading the decliners.

On Polymarket, the implied probability of traffic through the Strait of Hormuz returning to normal before the end of April is 17%, implying a lack of confidence in the imminence or durability of a ceasefire, according to a Tuesday note from Macquarie.

"A whole civilization will die tonight, never to be brought back again. I don't want that to happen, but it probably will," Trump said in a Truth Social post as his Tuesday deadline for Iran to reach a ceasefire deal with the US and open the Hormuz chokepoint loomed. "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 mediators continue, the Wall Street Journal reported.

The US conducted more than 50 strikes on military targets on Iran's Kharg Island early Tuesday, the WSJ cited two US officials as saying. The Israeli military said it had struck eight bridge segments across Iran, and Prime Minister Benjamin Netanyahu said train tracks were also struck, the news report added.

West Texas Intermediate crude oil futures rose 0.5% to $113.01, while Brent crude futures declined 1.3% to $108.28.
