Oil Prices Slide Further After U.S.-Iran Peace Deal

Global oil prices extended their decline after the United States and Iran finalized an initial agreement to end their war, with Brent crude dropping $1.19 to $78.36 per barrel on June 18, 2026. U.S. benchmark crude also fell, slipping $1.56 to $74.45 per barrel. The deal includes a 60-day negotiating period to reach a final accord on Iran’s nuclear program and requires Tehran to dilute its stockpile of highly enriched uranium. In exchange, the U.S. will waive sanctions, allowing Iran to resume unrestricted oil sales—a major concession that immediately boosted market sentiment. Oil prices remain above pre-war levels of around $70 but are well below the $100-plus range seen weeks earlier. The easing of geopolitical tensions sent ripples through financial markets, with U.S. stock futures rebounding ahead of the opening bell. The S&P 500 futures rose 0.6%, the Dow Jones Industrial Average edged up 0.2%, and the Nasdaq futures gained 1.3%, clawing back losses from the previous day driven by speculation over potential Federal Reserve interest rate hikes. Fed Chair Kevin Warsh, in his first news conference, avoided forecasting the federal funds rate for 2026 but announced plans to overhaul how the central bank communicates rate expectations, removing forward guidance from Fed statements. Nine of the 18 members of the Fed’s rate-setting committee signaled support for higher rates this year, with six favoring two or more quarter-point increases. Higher rates could curb inflation but risk slowing economic growth and depressing asset prices. The oil price drop provided a tailwind for travel-related stocks, with Delta, United, and American Airlines rising between 1.5% and 2%, while cruise lines Royal Caribbean and Carnival climbed more than 2%. In Asia, Japan’s Nikkei 225 surged 1.7% to a new closing high of 71,053.49, fueled by optimism over the war’s end and strong demand for high-tech shares amid the AI boom. South Korea’s Kospi also set records, gaining 2.3% to 9,063.84, driven by gains in chipmakers Samsung Electronics (up 4.6%) and SK Hynix (up 6.5%). Taiwan’s Taiex rose 1.3%, while Australia’s S&P/ASX 200 slipped 0.6% to 8,911.10. In Europe, Germany’s DAX edged 0.1% lower, France’s CAC 40 ticked down 0.2%, and Britain’s FTSE 100 shed 1%. Hong Kong’s Hang Seng fell 2.1% to 23,792.35, and China’s Shanghai Composite dipped 0.4% to 4,090.48.
