S&P 500 rallies toward all-time high while Brent crude tumbles amid conflicting US-Iran diplomacy signals

US stock markets surged toward record territory on Monday as President Donald Trump claimed negotiations with Iran were underway, even as Tehran publicly denied any direct talks with Washington. The rally pushed the S&P 500 within striking distance of its all-time closing high, while oil prices tumbled roughly 5 percent before recovering slightly in early Asian trading on Tuesday.

The market movements reflect investor sensitivity to any signals of de-escalation in the US-Israel war on Iran. Trump's assertion that he wants to give Tehran "every last chance" to reach a deal before renewed military strikes has introduced cautious optimism, though the conflicting accounts from both capitals underscore the fragility of any potential diplomatic breakthrough.

Major Market Movements

The S&P 500 climbed 1.5 percent on Monday, ending just below its closing record of 7,620.90 set on June 2. The tech-heavy Nasdaq Composite jumped 2.1 percent, closing 4.3 percent below its all-time peak of 27,093.90, also reached on June 2. The Dow Jones Industrial Average rose 1.3 percent to hit a record high of 53,178.41.

Most of the "Magnificent Seven" tech giants posted substantial gains. Meta Platforms led with a 6 percent rise, while Microsoft, Amazon and Alphabet each climbed between 4.4 percent and 4.9 percent. Nvidia rose 2.9 percent and Tesla jumped 3.5 percent. Apple was the only member of the group not to register a significant gain. After-hours trading extended the rally, with S&P 500 futures rising more than 0.2 percent.

Diplomatic Uncertainty

The market rally unfolded against a backdrop of sharply conflicting narratives from Washington and Tehran. Trump stated on Monday that talks with Iran were underway and that he intended to give Tehran "every last chance" to sign a deal before facing renewed strikes. His remarks came one day after he announced he had called off what he described as the "biggest attack since World War II" following discussions with Gulf leaders.

Iran's Ministry of Foreign Affairs spokesman, Esmaeil Baghaei, directly contradicted Trump's account earlier on Monday, telling a news conference that Tehran was not engaged in talks with Washington and had no meetings with US officials planned. Baghaei confirmed that Iranian officials were negotiating with Oman on allowing ships to transit the Strait of Hormuz, adding that issues between the US and Iran would need to be addressed in "next stages."

Oil and Asian Markets React

Brent crude, the primary international oil benchmark, fell about 5 percent on Monday before recovering as Asian markets opened on Tuesday. Brent futures were trading at approximately $85 per barrel as of 04:00 GMT, up more than 1.3 percent from Monday's close.

Asian equities declined on Tuesday after initial morning gains. South Korea's Kospi fell 1 percent, Japan's Nikkei 225 dropped 0.7 percent, and Hong Kong's Hang Seng Index dipped 0.5 percent. Melissa Brown, managing director of Investment Decision Research at SimCorp, expressed surprise at the magnitude of the US rally, noting it came "against the backdrop of relatively negative sentiment, and without a real fundamental reason to support it."

What Lies Ahead

The situation remains fluid as markets weigh Trump's diplomatic overtures against Tehran's public denials of direct engagement. The gap between the two governments' accounts leaves investors with no clear signal on whether negotiations will materialize. With Brent crude stabilizing around $85 per barrel and US futures holding gains in after-hours trading, markets appear to be pricing in cautious optimism while awaiting concrete developments on the diplomatic front.
