Oil prices spike as U.S. ramps up pressure on Iran

Global oil prices surged on August 20, 2026, after a ballistic missile strike in the United Arab Emirates triggered nationwide alerts—the first such warning in weeks—fueling fresh geopolitical jitters. Brent crude, the international benchmark, jumped 2.5% to $93.90 per barrel, up from roughly $72 before the Iran-linked conflict escalated. U.S. benchmark crude also climbed 2.8%, reaching $86.72 per barrel. The spike followed President Donald Trump’s threat to escalate economic pressure on Iran, deepening concerns over a prolonged regional crisis and potential disruptions to oil supply through the Strait of Hormuz. Meanwhile, the U.S. Treasury Department announced plans to at least double the size of its bond buybacks, a move aimed at easing pressure on share prices by pushing bond yields lower. U.S. stock futures showed little movement: the S&P 500 was flat, the Dow Jones Industrial Average slipped 0.1%, and Nasdaq futures edged up 0.1%. U.S. government bond yields fell after the announcement, with the 10-year Treasury yield dropping to 4.68% and the 30-year yield easing to around 5.22%. In Asia, bond yields also retreated, with Japan’s 10-year government bond yield falling to approximately 2.85%. The national debt surpassed a record $40 trillion on August 19, driven by soaring defense spending and U.S. military engagement in the Middle East. Walmart’s stock dropped more than 6% before the market opened as the retail giant issued a cautious full-year outlook, serving as a bellwether for consumer spending. Investors are also awaiting the latest U.S. unemployment data after jobless claims rose to 209,000 two weeks ago, up from 200,000 the prior week and above expectations. In European markets, Germany’s DAX fell 0.5% to 25,960.44, France’s CAC 40 slipped 0.4% to 8,466.75, and the UK’s FTSE 100 dropped 0.3% to 10,707.92. Asian equities, however, traded higher. The U.S. dollar strengthened to 158.50 Japanese yen from 158.16 yen, while the euro rose to $1.1696 from $1.1677.
