Oil Hits $100 as Houthi Tanker Strikes and U.S.-Iran Threats Rattle Markets
Global oil prices surged past $100 a barrel on Thursday as fears of a widening war between the United States and Iran sent stocks tumbling [203300]. The spike follows a series of escalating attacks by Iran-backed Houthi forces on Saudi oil tankers in the Red Sea, combined with fresh U.S. threats to strike Iranian infrastructure.
The Iran-aligned Houthi group struck two Saudi oil tankers in the Red Sea this week, part of a declared naval blockade against Saudi Arabia [202517]. The attacks threaten a second major chokepoint for global oil supplies—the Bab al-Mandeb strait—where Houthi forces have already prepared drones and missiles for potential strikes, causing some cargo ships to turn back [202167]. The strait, a narrow 20-mile-wide passage linking the Red Sea to the Gulf of Aden, handles nearly 10 percent of global seaborne oil [202167].
In response, U.S. President Donald Trump repeated a warning to Iran that any further attacks on ships in the Strait of Hormuz will be met with strikes on Iranian bridges and power plants [202923]. Trump also announced "major combat operations" against Iran involving massive joint U.S.-Israeli strikes, though no details on timing or scope were provided [203276]. Meanwhile, the U.S. military struck a tanker from Iran's "shadow fleet" in the Strait of Hormuz—a vessel used to transport Iranian oil in violation of sanctions—marking a significant escalation [201688].
Iran has warned that any attack on its infrastructure will be met with strikes on regional facilities, though it did not specify which countries or targets [198705]. A U.S. airstrike at Iran's Shalamcheh border crossing with Iraq killed two people, Iranian officials confirmed [202461]. The U.S. has also informed Israel that it plans to escalate airstrikes near the city of Qom in the coming days [202476].
The conflict has now directly threatened global economic stability, with analysts noting that the surge in oil prices has become too significant for investors to ignore [203300]. Gulf states are watching with growing fear as the pattern of strikes and counterstrikes risks spilling into a broader regional war [200164].
