Brent crude futures climbed 99 cents, or 1.2%, to $83.48 a barrel as traders weighed fresh concerns regarding the operational status of the Strait of Hormuz.
Reports indicate that both Iran and Oman are considering potential restrictions on the waterway, a development that threatens to disrupt one of the world's most vital energy chokepoints.
The Strait handles roughly a fifth of global oil consumption, making any threat to its openness a primary driver of supply-side anxiety.
The price move extends a broader rally in energy markets that has been fueled by escalating tensions in the region.
Oil prices had already surged following reports that Iran struck "hostile targets" within the Strait, a significant escalation in the ongoing conflict with the United States.
The current repricing reflects market anxiety that the narrow waterway could face a blockade or severe disruption, triggering a broad reassessment of supply risks across global energy flows.
