U.S. stock futures fell Wednesday as President Donald Trump threatened more action against Iran after negotiations stalled, with chip stocks adding to the pressure ahead of a closely watched inflation report.

The S&P 500 futures contract was off 0.91%, while the Nasdaq 100 futures contract lost 1.32%. Dow Jones Industrial Average futures pointed to an opening decline of around 449 points, equivalent to roughly 0.9%. Oil prices moved higher alongside the equity declines, with West Texas Intermediate crude futures rising about 1.4% to around $89.37 a barrel and Brent crude futures climbing about 1% to above $92 a barrel.
