US equity futures fell Tuesday, with Dow contracts dropping more than 400 points, as energy prices climbed toward $100 a barrel and stoked inflation worries before this week's price data. S&P 500 and Nasdaq 100 futures posted smaller declines.

Dow futures dropped 400 points, or 0.7%, as crude oil climbed toward $100 a barrel, reviving inflation concerns before US price data due this week.
The slide tracked a surge in energy costs after Iran's navy chief warned vessels passing through the Strait of Hormuz could require approval or face targeting, raising the risk of disruption through the chokepoint that carries a large share of the world's seaborne oil. WTI crude has pushed past $100 a barrel, according to market reports, extending a rally that has redrawn the inflation outlook for the second half of the year.
S&P 500 contracts lost 0.2% and Nasdaq 100 futures slipped about 0.1%, a shallower decline than the Dow as investors weighed the energy-driven inflation scare against the broader market's recent gains. The repricing rippled across assets, with Asian equities under pressure — Japan's Nikkei 225 fell about 2% — and gold holding near elevated levels as investors sought havens.
The stakes for equities hinge on this week's US price data, including the PCE inflation gauge the Federal Reserve tracks most closely. A hot reading would reinforce the oil-driven inflation concern and push back expectations for rate cuts, pressuring the rate-sensitive corners of the market that have driven much of this year's advance. Fed Chair Kevin Warsh is also scheduled to speak at Jackson Hole, offering a fresh read on the policy path after the energy shock.
For portfolio managers, the move reopens a question that had faded through the summer: whether inflation is genuinely returning to the Fed's 2% target. Crude near $100 feeds directly into headline inflation and consumer expectations, and sustained prices at that level would force the central bank to hold borrowing costs higher for longer than markets currently price. The coming data will determine whether Tuesday's futures slide marks a one-day repricing or the start of a broader pullback in an equity market that has been pricing in a steady easing cycle.
