Wall Street closed lower on Tuesday as fading optimism surrounding a potential U.S.-Iran diplomatic deal and a broader technology sector sell-off weighed on major indices. According to preliminary data from The Economic Times, the S&P 500 fell 25.32 points, or 0.33%, to finish at 7,727.79. The Nasdaq Composite dropped 160.36 points, or 0.60%, to close at 26,445.00, while the Dow Jones Industrial Average lost 188.41 points, or 0.35%, ending the session at 53,787.57.
Strait of Hormuz Standoff Dims Market Sentiment
Investor optimism evaporated following remarks from Tehran regarding the ongoing conflict in the Middle East. The newly appointed secretary of Iran’s Supreme National Security Council stated that the Strait of Hormuz will remain closed until the United States changes its behavior and accepts Iranian conditions to end the war, as reported by The Economic Times.
Brent crude futures held near one-week highs during choppy trading sessions, while the S&P 500 energy sector index climbed. Ross Mayfield, investment strategy analyst at Baird in Louisville, Kentucky, noted the persistent friction in reaching a diplomatic consensus. “As has been the case for months, it’s just really hard to come to an agreement that works for everyone. Oil is a little higher, pricing in more uncertainty around that,” Mayfield said, adding that while the market gyrates around the conflict, it has not proven to be the severe headwind many initially feared.
Technology Sector Losses and Corporate Moves
Weighing heavily on the S&P 500 and Nasdaq, major technology and retail giants stumbled during the Tuesday session. Amazon and Alphabet each experienced declines, dragging down major benchmarks alongside shares of SpaceX. The losses interrupted momentum from the previous week, when strong corporate earnings pushed the S&P 500 to all-time highs and the Nasdaq was down about 2% from its record high close on June 2.
Amid the broader market retreat, alternative asset managers bucked the trend. Apollo Global and Blackstone both rallied after recent announcements that financial institutions partnered with Nvidia to establish compute-financing platforms aimed at mobilizing more than $500 billion, according to The Economic Times. In individual stock movements, Jabil climbed after UBS upgraded the electronics firm’s stock from “neutral” to “buy.” Conversely, sportswear brand On saw its U.S.-listed shares tumble after missing sales estimates, and liquefied natural gas company Venture Global fell following a slight miss on second-quarter revenue.
Upcoming Inflation Data and Federal Reserve Policy
Market participants are now turning their attention toward crucial consumer and producer price inflation reports scheduled for release over the next two days. These figures will heavily shape expectations regarding the Federal Reserve’s monetary policy path, particularly given Chair Kevin Warsh’s goal of reducing guidance on monetary policy. According to the CME FedWatch tool, traders remain closely divided on the likelihood of an interest rate hike at the central bank’s upcoming September meeting.

Rising energy costs driven by the Iran conflict have complicated inflation forecasts for central banks globally, leaving investors vigilant as they parse incoming economic data for clues on future borrowing costs.
