11:45 AM EDT, 03/24/2026 (MT Newswires) -- US equity indexes were mixed in midday trading on Tuesday as confusion surrounded the state of truce talks with Iran.

The Nasdaq Composite declined 0.3% to 21,889.1, while the S&P 500 rose less than 0.1% to 6,585.2, and the Dow Jones Industrial Average climbed 0.3% to 46,352.5.

All three gauges jumped while crude oil futures sank with US government bond yields on Monday after President Donald Trump said in a social media post that the US will not attack Iran's energy infrastructure for five days amid ongoing productive talks between the two countries that could result in a deal to end the war.

CNN reported Tuesday, citing an unnamed Israeli official, that a deal to end the Iran war "does not appear to be tangible right now," as another wave of strikes were carried out across Iran while Tehran launched attacks on Tel Aviv.

The state of talks remains unclear, with Iran disputing Trump's assertion that the US and Tehran held discussions over the weekend, the CNN news report said. Other countries are pushing for a diplomatic solution, with Pakistan offering to host talks involving Iran, Israel and the US, the report added.

West Texas Intermediate crude oil futures jumped 3.7% to $91.38.

Most US Treasury yields rose, with the 10-year up 3.2 basis points to 4.37% and the two-year higher by 4.9 basis points to 3.88%.
