US stocks tumble as Israel-Iran escalation drives oil surge
Brent crude breaches $73 amid fears of Strait of Hormuz disruption, reigniting inflation concerns
US stocks fell sharply on Friday as military escalation between Israel and Iran sent crude oil prices surging, reigniting concerns about inflation and economic growth just as investors were grappling with broader market headwinds.
The S&P 500 dropped 0.5% to 6,878.88, while the technology-heavy Nasdaq Composite sank 0.9% to 22,668.21, marking its worst monthly performance since March of last year with a 3.4% decline for February. Technology and financial stocks led the losses, with Nvidia tumbling more than 5%, extending a recent slide despite strong earnings results.
Brent crude oil surged more than 3%, briefly exceeding $73 per barrel, after Israel launched preemptive airstrikes on Iran citing an anticipated missile and drone attack. Explosions were reported in Tehran, and Israel closed its airspace in anticipation of retaliation. The escalation raised fears of potential disruption to shipping through the Strait of Hormuz, the critical waterway through which approximately 21% of global petroleum liquids transit, according to energy analysts.
The sudden spike in energy prices compounded existing market concerns over elevated inflation. US wholesale inflation data released earlier in the week showed producer prices rising 2.9% last month, significantly higher than the 1.6% increase economists had anticipated. The combination of higher energy costs and stubborn inflation has fueled speculation that the Federal Reserve may delay interest rate cuts that investors had been counting on for 2026.
"Even without direct supply disruptions, geopolitical tensions in the Middle East often embed a 'risk premium' into oil prices," energy analysts noted. Past escalations have seen Brent crude jump 6-13%, with prices reaching into the $70-$78 per barrel range. Should the conflict lead to a full shutdown of Iranian oil exports or threaten shipping through the Strait of Hormuz, analysts warn prices could settle closer to $90 per barrel or potentially exceed $130 in severe disruption scenarios.
The financial sector also faced pressure, with Apollo and Jefferies falling between 8.6% and 9.3% on fears surrounding private credit contagion. However, not all markets moved in lockstep—London's FTSE 100 hit a new record high, boosted by rising energy and resources stocks that benefit from higher commodity prices.
Investors are now watching for further developments in the Middle East while also monitoring upcoming economic data releases for clues about the Federal Reserve's next moves. The confluence of geopolitical risk, elevated inflation, and concerns about artificial intelligence's disruptive impact on various business models has created a challenging environment for risk assets.
