Global oil prices rose sharply on September 10, with Brent crude settling at $107.63 a barrel and U.S. West Texas Intermediate closing at $102.48 a barrel, according to market data reported by major financial outlets. Both benchmarks reached their highest levels since mid-May.

The gains followed reports of intensified attacks on shipping near the Strait of Hormuz and the Red Sea. Iran said it had targeted multiple vessels after U.S. forces struck Iranian oil tankers earlier in the week. The capture of the Yemeni port of Mokha by Houthi forces the same day added to concerns about the Bab al-Mandab Strait.

Traders cited prolonged disruption risk in key Middle East energy corridors. Gasoline prices in the United States also moved higher. Analysts noted that supply volumes through the Strait of Hormuz remain below pre-conflict levels. No immediate change in production quotas from major producers was announced.

The price movement marks the largest single-day advance in nearly two months and reflects ongoing uncertainty surrounding the multi-month conflict involving the United States, Iran, and regional actors.
