Crude oil prices fell sharply on Tuesday as traders viewed the latest U.S. sanctions campaign against Iran as posing less immediate risk to global oil supplies than a further military escalation. Brent crude fell $3.59, or 3.9%, to $88.58 per barrel, while WTI declined $2.65, or 3.1%, to $82.36 per barrel. Both benchmarks reached their lowest levels since August 13.
The market’s focus shifted toward economic pressure after the United States announced expanded sanctions targeting Iran and its trading partners. The measures were viewed as less immediately disruptive to oil supplies than renewed military action, particularly as details surrounding the targeted countries and the timing of potential penalties remain unclear.
Despite the sharp decline, supply risks remain elevated. An oil tanker was struck and disabled by an unidentified projectile near Oman’s coast, while shipping activity through the Strait of Hormuz continued to deteriorate. Only two commodity tankers transited the waterway on Monday, the lowest daily total since early May.
The Strait of Hormuz remains a critical concern for global energy markets, as roughly one-fifth of global oil consumption moved through the waterway before the conflict began on February 28. Continued restrictions have contributed to the drawdown of both commercial and strategic petroleum inventories as countries work to offset disrupted supplies.
Additional disruptions were reported outside the Middle East. Ukraine struck the Novoshakhtinsk oil refinery in Russia’s Rostov region, forcing the facility to suspend operations, while a fire broke out at Kazakhstan’s Atyrau refinery.
While the shift toward economic pressure reduced some immediate concerns about further military escalation, severely restricted shipping through the Strait of Hormuz and continued attacks on energy infrastructure leave significant supply risks in place.
