Brent crude surged past $100 per barrel, closing near $100.69 after reports of tanker attacks in the Red Sea, triggering a swift shift to risk-off sentiment in the stock market. This roughly 7% single-day spike rattled investors, particularly hitting growth stocks sensitive to rising input costs and inflation fears.
The S&P 500 ended the day down 1.21%, with tech giants leading the downturn. The Nasdaq Composite dropped about 2.15% as concerns grew over the balance between escalating AI spending and the rising price pressures tied to oil’s jump. Tesla shares plunged roughly 14 15%, while Alphabet’s stock fell around 7%, following earnings reports that reignited doubts about future capital expenditures in AI infrastructure.
Energy stocks and certain defensive sectors saw some buying interest, contrasting with the sharp declines in long-duration growth stocks. The spike in oil prices added to inflation worries, hinting at sustained rate increases and tighter financial conditions ahead. This dynamic compounded the pressure on technology stocks, whose valuations depend heavily on future earnings discounted back to present value.
Higher oil prices impact equities through three main channels: inflation expectations rise, corporate margins get squeezed as transportation and energy costs increase, and geopolitical risks push investors to demand higher risk premiums. The rapid nature of the oil price jump amid ongoing supply concerns intensified these effects, particularly in sectors reliant on growth narratives.
The tech sector’s selloff was exacerbated by earnings results that fueled debate over whether AI-driven revenue growth can offset the substantial infrastructure costs. Growth stocks, behaving like long-duration assets, suffered as rising rates and inflation fears lowered the present value of expected earnings. This effect was most visible in companies with the highest valuations.
