Iran conflict engulfs Gulf bases and Hormuz while Micron expands AI-chip capacity

U.S. markets were closed on Saturday. The United States and Israel launched strikes on Iran, Iran and allied forces extended the confrontation to Gulf military sites, and reports later described the death of Ayatollah Ali Khamenei and other senior Iranian officials. Oil-tanker traffic through the Strait of Hormuz stopped before Iran announced the strait's closure, while OPEC+ considered a larger output increase. Away from the conflict, Micron opened a $2.75 billion assembly-and-test facility in India for AI-driven memory demand.
