US equity indexes closed mixed, albeit off session lows, as President Donald Trump agreed to delay a "large-scale" attack on Iran on Tuesday at the request of leaders from the Middle East negotiating with Tehran.
The Nasdaq Composite fell 0.5% to 26,090.73, with the S&P 500 down less than 0.1% to 7,403.05 on Monday. The Dow Jones Industrial Average rose 0.3% to 49,686.12. Technology and industrials led decliners at the close. Energy, financials, and consumer staples were among the top gainers.
President Trump will "hold off" on a Tuesday plan to attack Iran, citing a request from Qatar, Saudi Arabia, and the United Arab Emirates as he said negotiations to end the war grow more "serious," CNN reported Monday. "This Deal will include, importantly, NO NUCLEAR WEAPONS FOR IRAN," Trump was cited as saying.
Trump also instructed his leadership "to be prepared to go forward with a full, large-scale assault of Iran, on a moment's notice" if a deal isn't reached, according to the president's Truth Social post.
Meanwhile, Iran offered an updated peace proposal, which the White House adjudged lacking meaningful improvement over the previous offer, rendering the latest version insufficient to reach a deal to end the war, a senior US official and a source briefed on the issue told Axios.
Separately, the US has agreed to release a quarter of Iran's frozen funds - totaling tens of billions of dollars - held in foreign banks, a senior Iranian source told Reuters. Washington has shown more flexibility in allowing Iran to continue some peaceful nuclear activity under the supervision of the International Atomic Energy Agency, the source told the news agency.
