Brent crude oil prices rose above $90 per barrel on Monday as intensifying hostilities between the U.S. and Iran sparked supply concerns [1].

The price surge reflects growing market anxiety that military escalation could disrupt oil shipments through the Strait of Hormuz, a critical global transit point. Any significant blockage in this corridor typically triggers immediate volatility in energy markets.

Brent crude reached approximately $90.8 per barrel during early Asian trading [1]. Depending on the reporting source, the price rose between two percent and three percent on the day [1, 2]. West Texas Intermediate (WTI) also saw gains, rising to just over $85 per barrel [3].

The market volatility follows a series of fresh airstrikes and missile attacks. Iranian missile strikes resulted in the deaths of two U.S. service members, while a third is presumed dead [4]. These represent the first U.S. combat deaths in the region since April 2024 [4].

Trading desks in Asia reported the price movements as the geopolitical situation deteriorated over the weekend [1, 2]. The risk of tightened shipments remains a primary driver for the current spike, as traders hedge against potential closures, or attacks on tankers in the Middle East [1, 4].

U.S. and Iranian forces continue to engage in the region, contributing to the uncertainty. Market analysts are monitoring the Strait of Hormuz closely, as the majority of the world's exported oil passes through this narrow waterway [1, 2].

The breach of the $90 threshold indicates that oil markets are now pricing in a high probability of physical supply disruptions rather than just geopolitical tension. Because the Strait of Hormuz is a single point of failure for global energy transit, continued U.S.-Iran combat operations could lead to sustained price inflation, impacting global transport costs and consumer inflation rates.
