NEW YORK — U.S. stocks posted their strongest daily gains in two months on Thursday after signs of a potential diplomatic breakthrough involving Iran raised hopes that disruptions to global oil supplies could ease and help reduce inflationary pressures.
The rally accelerated after President Donald Trump announced on social media that discussions with Iran’s leadership had reached an advanced stage and that details of a potential agreement would be revealed soon. Investors interpreted the comments as a signal that tensions threatening energy markets could diminish.
The benchmark S&P 500 climbed 1.8%, while the Dow Jones Industrial Average advanced nearly 930 points, or 1.9%. The technology-heavy Nasdaq Composite led major indexes with a 2.5% gain.
Oil Prices Retreat on Diplomatic Optimism
Energy markets responded quickly to the prospect of a deal that could restore more stable oil flows through the Strait of Hormuz, a critical shipping route for global crude exports.
U.S. benchmark crude oil fell 2.6% to $87.71 per barrel, while Brent crude, the international standard, dropped 2.9% to $90.38. Although prices remain significantly above levels seen before the conflict, the decline offered investors relief after months of concerns about supply disruptions.
Market participants have closely monitored developments involving Iran because interruptions in Middle Eastern oil shipments have contributed to higher fuel costs worldwide and increased inflationary pressures across major economies.
Inflation Remains a Key Concern
The market rally came despite fresh economic data showing inflation remains elevated.
A Labor Department report released Thursday indicated wholesale prices increased more than economists had expected in May, highlighting ongoing cost pressures within the economy.
Higher energy prices have played a major role in pushing inflation higher in recent months. Rising fuel costs have affected businesses, consumers and policymakers alike, increasing uncertainty over the future path of interest rates.
Investors are particularly sensitive to inflation developments because higher prices can prompt central banks to maintain restrictive monetary policies, slowing economic growth and weighing on financial markets.
Treasury Yields Fall as Rate Fears Ease
Bond markets reflected growing optimism that lower oil prices could help reduce inflation risks.
The yield on the 10-year U.S. Treasury note fell to 4.45% from 4.55% a day earlier, a notable move that signaled increased demand for government bonds.
Lower oil prices could reduce pressure on the Federal Reserve to raise interest rates further. Following Trump’s comments, traders scaled back expectations that the central bank would need to tighten monetary policy later this year.
Investors are also watching whether the Federal Reserve, now led by Chair Kevin Warsh, could eventually consider easing policy if inflation trends improve.
Technology and AI Stocks Lead Gains
Technology companies and semiconductor-related stocks were among the market’s strongest performers.
Chip equipment manufacturers posted some of the biggest advances of the session. Shares of Lam Research jumped 12.7%, while KLA rose 12.9%.
Marvell Technology gained 11.1%, extending a period of unusually volatile trading linked to investor enthusiasm surrounding artificial intelligence infrastructure and semiconductor demand.
AI-related stocks have experienced sharp swings in recent weeks as investors weigh enormous spending commitments against questions about future profitability and long-term returns.
Oracle Falls Despite Strong Earnings
Not all technology companies participated in the rally.
Oracle shares dropped 8.5% despite reporting quarterly profit results that exceeded analyst expectations. Investors focused instead on the company’s plans to raise an additional $40 billion through borrowing and stock sales to support artificial intelligence investments.
The decline reflects broader market concerns about the significant capital expenditures being undertaken by companies seeking to expand their AI capabilities.
Some investors remain cautious about whether current spending levels can generate the revenue growth and profitability necessary to justify lofty valuations across the sector.
Small-Cap Stocks Outperform
Smaller companies benefited from the prospect of a less aggressive interest-rate environment.
The Russell 2000 index, which tracks smaller U.S. businesses, climbed 3%, outperforming major large-cap benchmarks.
Small-cap stocks tend to be more sensitive to borrowing costs because many rely on external financing to fund growth and expansion. Lower interest-rate expectations can therefore provide a meaningful boost to the sector.
Global Markets Mixed
Outside the United States, stock market performance was more subdued.
European indexes finished modestly higher, with London’s FTSE 100 gaining 0.5%.
Asian markets delivered mixed results. Hong Kong’s Hang Seng Index declined 0.7%, reflecting continued caution among investors despite improving sentiment in U.S. markets.
Market Outlook
Thursday’s rally underscored how closely financial markets remain tied to developments in global energy markets and monetary policy expectations.
Investors will continue monitoring diplomatic efforts involving Iran, oil price movements and upcoming inflation data for clues about the direction of interest rates and economic growth.
For now, hopes that geopolitical tensions could ease and energy costs might stabilize have provided Wall Street with a significant boost after weeks of heightened volatility.
