Escalating geopolitical tensions across key Middle Eastern shipping lanes have sent global oil prices surging toward the $100 per barrel threshold, sparking widespread uncertainty across international financial markets on Thursday. The latest upward price movement came in response to continued attacks on Red Sea commercial shipping by Iran-aligned Houthi rebels, paired with a sharp threat of major military retaliation against the group from former U.S. President Donald Trump.
Brent Crude, the global benchmark for international oil trade, jumped more than 5.7% to settle near $99.42 per barrel by 1100 GMT, just a hair below the psychologically significant $100 mark that investors and analysts have warned would signal a major shift in global energy market dynamics. U.S. benchmark West Texas Intermediate crude also climbed 4.5% to reach $90.75 per barrel.
The disruption to Red Sea shipping has emerged as a critical flashpoint for energy markets, as Saudi Arabia has re-routed millions of barrels of oil exports through the waterway that normally pass through the Strait of Hormuz – another strategically vital energy choke point already facing elevated geopolitical risk. A prolonged closure or sustained disruption to either route would pull substantial volumes of oil off the global market, tightening supplies even further.
Neil Wilson, a UK-based investor strategist at Saxo, noted that there are currently no visible signs of a diplomatic breakthrough to de-escalate tensions, as both the U.S. and Iran have adopted hardened positions. “Investors are in a wary mood, as fresh jitters over the ongoing energy crunch hit market sentiment,” added Susannah Streeter, chief investment strategist at Wealth Club. “With both the Strait of Hormuz and the Red Sea now under increasing pressure, markets are bracing for the possibility that the conflict could disrupt key energy routes and keep oil prices elevated for an extended period.”
Higher sustained oil prices also raise the specter of renewed global inflationary pressure, which could force central banks around the world to hold interest rates higher for longer – or even implement additional rate hikes. This dynamic was on full display Thursday, as European Central Bank President Christine Lagarde confirmed that some policymakers had considered a rate hike at the bank’s latest monetary policy meeting before the governing council ultimately voted to hold rates steady.
Major U.S. stock markets tumbled in early trading, with all three primary benchmark indices falling more than 1% by mid-session. The tech-heavy Nasdaq Composite led the declines, dropping 1.8%, as all of the so-called Magnificent Seven large-cap technology stocks ended the day in negative territory. Shares of Alphabet fell 6% after the company raised its full-year artificial intelligence capital expenditure forecast to as much as $205 billion, a figure far higher than Wall Street analysts had projected. Tesla shares slumped 9.6% following a weaker-than-expected quarterly profit report and an announcement that the firm would double its capital expenditure compared to the same quarter in 2025.
Patrick O’Hare, an analyst at Briefing.com, pointed out that the scale of the index-level losses was not out of line with broader market conditions, noting that many non-tech stocks received a boost from positive earnings reports and that weekly U.S. unemployment claims data offered a reassuring signal about the strength of the domestic labor market. Even so, investor confidence in the AI sector has been tested in recent months, as concerns mount over stretched valuations and questions linger over when the trillions of dollars invested in the space will generate meaningful returns. Market participants are now turning their attention to next week’s earnings reports from Microsoft, Meta, and Amazon, which will be closely scrutinized for details of the companies’ planned capital spending.
Global market performance was mixed across regions on Thursday. Most major Asian stock markets recorded modest gains, buoyed by a long-awaited bounce for regional technology firms. Japan’s Nikkei 225 closed up 0.5%, while Hong Kong’s Hang Seng Index gained 1.3% and Shanghai’s Composite index edged up 0.3%. In contrast, European markets traded lower across the board in afternoon dealing, with London’s FTSE 100 falling 0.9%, France’s CAC 40 dropping 1.8%, and Germany’s DAX declining 1.5%.
In currency markets, the U.S. dollar strengthened against most major peer currencies. The Japanese yen hit a fresh four-decade low against the dollar, as investors priced in the persistent gap between the Bank of Japan’s ultra-low interest rate policy and the higher rates maintained by the U.S. and other major advanced economies. Rising oil prices and broader concerns over the outlook for Japan’s economy have added additional downward pressure on the yen in recent trading sessions.
