Dow Futures Slide Amid Iran Sanctions Uncertainty

US stock index futures slipped lower on Monday as investors weighed the potential impact of new US sanctions on Iran, awaited Nvidia's quarterly earnings, and looked ahead to Federal Reserve Chair Kevin Warsh's speech at the Jackson Hole symposium.

Market participants are also watching fresh US inflation data for clues about the central bank's next interest-rate move. Reuters reported that futures for the Dow, S&P 500, and Nasdaq were under pressure as markets assessed the possible economic consequences of new US sanctions on Iran.

The Treasury Secretary Scott Bessent is scheduled to provide details, while Tehran has warned of possible retaliation involving oil exports from the Gulf.
