Oil Plunge and Chip Selloff Create Dueling Forces as Markets Await Fed and Mega-Cap Earnings
Crude oil fell sharply after the US paused its strike campaign against Iran, easing geopolitical tensions. However, a semiconductor selloff, led by Nvidia's decline on news of financing guarantees for OpenAI's data center, erased the early relief rally, leaving the S&P 500 slightly lower.

The S&P 500 is caught between lower energy costs from de-escalation and tech weakness from AI capex concerns, with mega-cap earnings and the Fed decision looming as pivotal catalysts.
Markets are navigating a complex setup as an 8% oil crash from a US-Iran pause sparks an initial relief rally, but a semiconductor rout led by Nvidia caps gains ahead of a Fed decision and Magnificent Seven earnings.
