U.S. stock markets edged lower, giving back part of their recent gains, as investors grappled with volatile oil prices and conflicting signals around potential negotiations between the United States and Iran.
The S&P 500 fell 0.4%, while the Dow Jones Industrial Average slipped 0.2% and the Nasdaq dropped 0.8%, reflecting renewed caution after a brief rally earlier in the week.
Markets had initially been buoyed by President Donald Trump’s comments suggesting that talks with Iran were underway, raising hopes of easing tensions that have disrupted global energy supplies. However, those gains proved short-lived as uncertainty resurfaced, with Iranian officials denying any such negotiations.
Oil prices, a key driver of market sentiment, have been swinging sharply. After an initial drop in hopes of diplomacy, crude prices rebounded by more than 4%, underscoring continued concerns about supply disruptions linked to the conflict.
The volatility reflects broader fears that the war could keep energy markets tight, feeding inflation and complicating the outlook for interest rates. Treasury yields moved higher, with the 10-year yield rising to around 4.39%, signalling a shift in expectations that borrowing costs may remain elevated for longer.
The conflict has already disrupted flows through critical energy routes such as the Strait of Hormuz, which handles a significant share of global oil shipments, amplifying risks for both markets and policymakers.
Analysts say the market remains highly sensitive to geopolitical developments, with investor sentiment swinging between optimism over potential diplomacy and concern over prolonged conflict.
For now, the interplay between oil prices and geopolitical risk continues to dominate market direction, leaving equities vulnerable to further volatility as the situation evolves.
