U.S. Strikes Iran After Ship Attacks; Oil Surges, USO Rises

The U.S. military launched a fresh round of strikes against Iran on Wednesday, retaliating for Tehran's attacks on commercial ships near the Strait of Hormuz. President Trump ended a ceasefire and signaled further action, including a possible blockade. Oil prices jumped on the news. The United States Oil Fund (USO) rose in after-hours trading.

The strikes follow a series of incidents in the strait, a chokepoint for roughly 20% of global oil supply. Iran had targeted tankers over the past week, the Pentagon said. Trump's decision to abandon the ceasefire marks a sharp escalation. He told reporters the U.S. would 'not rule out a blockade' to stop Iranian aggression.

For oil markets, the risk is straightforward: a blockade of the Strait of Hormuz would cut off a significant portion of Middle Eastern crude. Traders said the probability of a sustained disruption remains low but has risen. The last time the strait faced a credible threat, in 2019, oil prices spiked 15% in a week.

USO offers direct exposure to near-term crude futures. The fund's Alpha Score sits at 40 out of 100, labeled Mixed, reflecting neutral sentiment among the quantitative models AlphaScala tracks. The score does not predict direction. It measures the balance of technical and fundamental signals. For traders, the score suggests the setup is not clearly skewed either way heading into the escalation. More detail is available on the USO stock page.

The broader energy sector also moved. Exxon and Chevron led gains among producers as the risk premium repriced. The most direct play remains USO, which rolls futures contracts monthly and can suffer from contango in prolonged disruptions. The fund's structure means it tracks spot prices closely over short horizons.

Whether the strikes expand or de-escalate will determine the next leg for oil. The White House has not set a timeline. The Pentagon said operations would continue as needed.
