Oil price spike risks slowing power-hungry AI expansion

Oil's sharp rally amid the Iran war has injected fresh volatility into semiconductor stocks and prompted new questions about the cost and pace of the AI boom. Shares of TSMC, Samsung Electronics, and SK Hynix swung sharply, at one point falling between 9% and 22%, as investors weighed rising energy and supply risks.

AI data centers are highly energy-intensive, driven by power-hungry graphics processing units and advanced cooling systems, making them vulnerable to rising power costs. Oil accounts for roughly 38% of total US energy consumption, and the US hosts most of the world's AI data centers.

While oil is not the primary source of electricity generation, higher crude prices tend to ripple across energy markets. Phelix Lee, an equity analyst at Morningstar, warned that higher energy costs for AI data centers could slow infrastructure buildouts, while fabs in Taiwan and South Korea would face growing cost pressures from higher LNG prices.
