Key Wall Street indices closed higher on Wednesday after reports signalled potential diplomatic outreach from Iran and US President Donald Trump pledged measures to stabilise oil markets.
The rebound was led by technology stocks, with investors encouraged by easing fears of immediate energy disruptions and fresh data showing resilience in the US economy.
Wall Street rebounds as tech stocks lead gains
The Dow Jones Industrial Average rose 238.14 points, or 0.49%, to 48,739.41; the S&P 500 gained 52.87 points, or 0.78%, to 6,869.50, and the Nasdaq Composite climbed 290.79 points, or 1.29%, to 22,807.48.
Technology stocks led the rally, helping the Nasdaq remain in positive territory since the weekend’s US-Israeli strike on Iran escalated tensions in the Middle East. The S&P 500 hovered near its all-time closing high reached in January.
A report by The New York Times said Iranian intelligence operatives had indirectly reached out to the Central Intelligence Agency following the attacks, though U.S. officials remain sceptical about the prospects for near-term de-escalation.
President Trump’s announcement of U.S. naval escorts for oil tankers through the Strait of Hormuz and the provision of political risk insurance helped calm fears of major supply disruptions.
Oil supply concerns ease, lifting market sentiment
Markets had been rattled by concerns that escalating conflict could disrupt oil flows and fuel inflation. The White House measures reduced immediate fears of energy supply shocks, supporting risk appetite.
Jim Awad, senior managing director at Clearstead Advisors LLC, told Reuters that the relief gave investors confidence to buy technology stocks that had sold off heavily in February.
Richard Bernstein, CEO of Richard Bernstein Advisors, said market volatility would hinge on whether the conflict proves short-lived or drags on long enough to affect the U.S. economy.
“That combination is giving the market some optimism, which will be tested over the coming weeks,” Awad said. “It is time to be realistic and not get carried away, either too bullishly or too bearishly.”
“If people think the war will be short-lived or ‘not an issue’ for the U.S. economy, then the stock market will likely rally,” Bernstein said. “The opposite seems true, too. Long-lived and impacting the US economy could mean more volatility.”
Geopolitics and economic data shape outlook
Several Middle Eastern countries have temporarily halted oil and gas production, while the U.S. is considering expanding its campaign inside Iran. The potential for energy supply disruptions has been a key driver of recent market swings.
Meanwhile, the Federal Reserve reported that U.S. economic activity rose slightly in recent weeks, with prices continuing to increase and employment stable. A private survey showed stronger-than-expected growth in private payrolls in February, and another report pointed to robust services-sector activity.
Biotechnology firm Moderna surged 16% after agreeing to pay up to $2.25 billion to settle a long-running legal dispute over a COVID-19 vaccine patent.
Investors will be closely monitoring developments in the Middle East and incoming economic data for clues on inflation and the Federal Reserve’s policy direction. Market sentiment is likely to remain sensitive to headlines on oil supply risks and diplomatic progress.
