Wall Street Climbs Toward Record Highs as Hopes Grow for Iran Peace Deal

By Anietie anii-bassey

U.S. stocks moved higher Tuesday as investors reacted positively to signs that negotiations aimed at ending the war between Iran and the United States could be gaining momentum, lifting confidence across global financial markets despite continued military clashes in the Middle East.

The rally on Wall Street came after President Donald Trump said talks with Iran were “proceeding nicely,” fueling hopes that the months-long conflict that has shaken global energy markets and driven inflation higher could eventually come to an end.

The S&P 500 climbed 0.8% after trading resumed following Monday’s market holiday. The Nasdaq composite surged 1.3%, powered by strong gains in major technology companies, while the Dow Jones Industrial Average hovered near the flatline, slipping by 25 points in late morning trading. All three major indexes remained close to record territory.

Investors appeared willing to focus on the possibility of diplomacy succeeding, even as fighting continued across the region. The U.S. military confirmed that it carried out what it described as “self-defense” strikes in southern Iran targeting missile launch facilities and boats allegedly involved in placing naval mines.

The renewed military activity highlighted the fragile nature of the ceasefire that has repeatedly shown signs of strain. Financial markets have repeatedly surged on optimism surrounding potential peace negotiations, only for renewed violence to spark fresh uncertainty.

Energy prices remained volatile as traders continued reacting to developments surrounding the Strait of Hormuz, the strategically critical waterway that has become central to the conflict.

Brent crude, the international oil benchmark, rose 3.8% Tuesday to reach $99.80 per barrel, recovering some of the steep 7.1% decline recorded a day earlier. Meanwhile, U.S. benchmark crude oil prices fell 3% to $93.74 per barrel in choppy trading that reflected uncertainty about future supply conditions.

Oil markets have dominated global financial sentiment since the United States and Israel launched strikes against Iran earlier this year. In response, Iran effectively closed the Strait of Hormuz to most oil tanker traffic, severely restricting the movement of crude exports from the Persian Gulf.

The disruption has sharply increased oil prices worldwide, worsening inflation pressures already troubling major economies and central banks.

Investors welcomed signs that negotiations could eventually reopen the vital shipping route and stabilize energy flows. Companies heavily dependent on fuel costs were among the strongest gainers on Wall Street.

United Airlines rose 6.6% as investors anticipated lower jet fuel costs if tensions ease, while cruise operator Carnival climbed 3.5% on hopes for reduced energy expenses and stronger travel demand.

Lower oil prices also helped calm the U.S. bond market after recent weeks of heavy volatility. Treasury yields fell as investors adjusted expectations for inflation and economic growth.

The yield on the benchmark 10-year U.S. Treasury note dropped to 4.49% from 4.56% at the close of trading last Friday.

The decline offered relief to investors after a recent surge in bond yields raised concerns about tighter financial conditions. Higher borrowing costs have already pushed average U.S. mortgage rates to their highest levels since last summer, adding pressure on homebuyers and businesses alike.

Analysts have also warned that persistently high borrowing costs could slow investment in artificial intelligence infrastructure, one of the major drivers supporting economic growth and stock market gains in recent years.

Technology stocks once again played a major role in lifting the broader market.

Micron Technology soared 17.7%, making it one of the strongest performers in the S&P 500 after analysts at UBS dramatically increased their price target for the semiconductor company. Analysts said they expect demand for computer memory chips to remain exceptionally strong as artificial intelligence systems continue expanding worldwide.

Micron shares have already tripled in value this year amid booming investor enthusiasm for AI-related companies and hardware suppliers.

The gains in technology shares helped offset losses elsewhere in the market.

AutoZone fell 11.6% after reporting quarterly revenue that slightly missed Wall Street expectations, despite posting stronger-than-expected profits. Company executives said weaker sales performances in Brazil and Mexico weighed on results during the quarter.

Despite ongoing geopolitical tensions and rising inflation concerns, most major American corporations have continued reporting stronger-than-expected earnings for the beginning of 2026. The resilient corporate performance has helped propel U.S. stock indexes toward repeated record highs even as uncertainty surrounding oil prices and the Middle East conflict persists.

Still, signs of economic strain among consumers remain visible.

A report released Tuesday showed U.S. consumer confidence slipped slightly in May, though the decline was smaller than economists had forecast. The data followed another survey released Friday indicating consumer sentiment had fallen to its lowest level on record as households continue grappling with rising prices and uncertainty about the economy.

Global markets outside the United States delivered mixed performances.

South Korea’s Kospi index jumped 2.5% as traders there reacted to Monday’s global rally after returning from a holiday closure.

In Europe, Britain’s FTSE 100 rose 0.5%, though gains were tempered by a sharp decline in shares of oil giant BP. The company’s stock dropped 5.1% after BP announced the removal of its chairman amid what it described as serious concerns involving governance standards, oversight and conduct.

In Japan, the Nikkei 225 slipped 0.2%, pulling back slightly after reaching a record high during the previous trading session.

Investors worldwide now remain focused on whether diplomatic talks with Iran can produce a lasting agreement capable of easing tensions in the Middle East, reopening critical oil shipping routes and reducing the inflationary pressures that have weighed heavily on the global economy for months.
