Stock Market Today: Dow, S&P 500, Nasdaq Futures Waver as Oil Rises Amid US-Iran Energy Conflict

US stock futures fluctuated overnight Sunday as investors sought to stabilize after another weak week for equities, while closely monitoring surging oil prices driven by the ongoing conflict between the US and Iran.

Futures tied to the Dow Jones Industrial Average (YM=F), S&P 500 futures (ES=F), and Nasdaq 100 futures (NQ=F) all hovered near the flatline.

This cautious start to the week follows a third consecutive weekly decline for the S&P 500 (^GSPC), which closed Friday at its lowest level of the year and its lowest point since November.

Oil prices continued to rise as the US-Israeli conflict with Iran disrupts traffic through the Strait of Hormuz. Both crude benchmarks surpassed $100 a barrel for the first time since 2022. In the latest development, US attacks on Kharg Island—Iran's main export hub—have intensified immediate supply concerns and raised future risks, as Iran has vowed retaliation against US energy facilities in the region.

In early Monday trading, West Texas Intermediate (CL=F) crude rose about 2% to approximately $100.90 per barrel, while Brent (BZ=F) crude increased roughly 2.6%, hovering above $105.

Investors will also be watching key domestic corporate and policy events this week. Nvidia’s (NVDA) annual GTC conference begins Monday with a keynote speech from CEO Jensen Huang. Additionally, the Federal Reserve is scheduled to hold its second policy meeting of the year, with markets widely expecting the central bank to keep interest rates unchanged.
