U.S. airstrikes on Islamic Revolutionary Guard Corps targets in Iran sparked market concerns. U.S. stocks closed lower on Tuesday, with the Dow Jones Industrial Average falling 412 points (0.8%), the S&P 500 down 0.7%, and the Nasdaq Composite down 0.9%. International oil prices surged by approximately 4%, with U.S. crude breaking above $89/barrel and Brent crude exceeding $93/barrel. Global bond markets faced pressure, as the U.S. 10-year government bond yield hit a new high since January 2025, and Japan's 10-year government bond yield touched 3% for the first time since 1996. Gold prices fell 1.9% to $4396/ounce. The airstrikes occurred a day after an oil tanker in the Strait of Hormuz was attacked by an unidentified projectile, and President Donald Trump had vowed retaliation.
