Oil Surges to $113 and Tech Stocks Plunge Amid Rising Iran Tensions
Geopolitical tensions with Iran and tech sector sell-offs rattled global markets, driving Brent oil to $113 and plunging U.S. Treasury yields. Despite broad gains in the S&P 500, mega-cap tech losses dragged the index down.
Geopolitical tensions involving Iran and Hezbollah have returned to the forefront of investor focus, driven by reports that Israel and the United States are weighing plans for military strikes against Iran. According to foreign sources cited in U.S. media, the prospect of renewed action has been discussed at military levels, though a final decision rests with U.S. President Donald Trump. The White House has clarified that the U.S. will not strike Iran prior to the elections. Concurrently, the U.S. State Department ordered non-essential personnel and their families to depart diplomatic missions in Saudi Arabia amid heightened regional security threats.
Financial markets reacted with pronounced nervousness. Brent crude oil prices climbed roughly 4% on Thursday to reach approximately $113 per barrel, fueled by fears of military escalation and potential disruptions to global energy supplies. Meanwhile, the yield on 10-year U.S. Treasury bonds plunged by 19.3 basis points to approximately 4.95%, marking the sharpest daily decline since the regional banking crisis of March 2023.
The simultaneous drop in yields and surge in oil prices presented a complex picture, as higher energy costs typically stoke inflation and push yields upward. However, investors appeared to seek a safe haven in government bonds amid growing anxieties over conflict and economic deceleration. Consequently, analysts noted that this movement should not be interpreted as the market pricing in a deflationary shock.
Simultaneously, technology and semiconductor stocks suffered heavy losses. The Philadelphia Semiconductor Index tumbled 6.7%, with Advanced Micro Devices (AMD) shares dropping 8.1%, Micron falling 6.26%, Nvidia down 4.4%, and CoreWeave losing about 10%. The Nasdaq Composite index dropped 2.6%, its steepest daily decline since June. Beyond geopolitical friction, investors expressed increasing concern over the sheer scale of capital expenditures in artificial intelligence infrastructure and whether corporations can successfully monetize those investments.
An exceptionally rare phenomenon unfolded within the S&P 500 index: approximately 337 out of its 500 constituent companies finished the trading session in positive territory, yet the index itself declined by 1.2%. Because the index is weighted by market capitalization, steep losses among a handful of mega-cap technology firms easily outweighed gains across hundreds of smaller components. Market analysts pointed out that this divergence is a rare occurrence observed only a few times since 1996.
The confluence of military tension, elevated energy prices, and weakness in tech equities underscores how regional developments continue to ripple through global financial systems. Even as potential military actions face delays, market uncertainty is already driving high volatility across oil, bond, and equity markets.
