US equity indexes traded mixed amid sliding crude oil prices as details of the Iran peace deal began to emerge.

The tech-heavy Nasdaq Composite fell 1% to 26,409.6, with the S&P 500 down 0.5% to 7,517.5, while the Dow Jones Industrial Average rose 0.7% to 52,037.9 ahead of Tuesday's close.

Technology was the standout decliner, while financials and industrials led the gainers.

The US will allow Iran to immediately begin selling oil and fuel under the deal to end the war, offering Tehran an early financial incentive to wind down the conflict, people familiar with Sunday's announcement of an interim deal with Iran told The Wall Street Journal.

A $300 billion private fund designed to trigger investment into Iran is outlined in the framework agreement, and more than half that sum has already been committed, a source with direct knowledge of the deal told Reuters.

Iranian Foreign Minister Abbas Araghchi said Israel's continued occupation of southern Lebanon would violate the deal, according to a report from the Associated Press. "Without the withdrawal of Israeli forces from the territories they occupied during this war, the war has not fully come to an end."

Crude oil futures traded at levels that are the lowest in more than three months. Front-month global benchmark North Sea Brent slumped 4.1% to $79.80 per barrel, and US West Texas Intermediate dived 4.6% to $77.03 per barrel after midday.
