USO is trading at $134.24, up 3.50% from the August 28 close of $129.70 as U.S. strikes on Iranian launchers on Larak Island near the Strait of Hormuz and Iran’s reported missile retaliation raise fears of disruptions to global crude shipments.

  • Reuters reported Brent above $90 and WTI up more than 2% early August 31.
  • The catalyst is geopolitical, not company-specific; mixed equity futures and no major U.S. release leave oil’s supply-risk premium dominant.
