Oil prices advanced on Thursday, October 22, as escalating tensions in the Middle East renewed concerns about disruptions to global energy supplies following a drone attack targeting Saudi Aramco’s Shaybah oil field.
Brent crude, the international benchmark, traded around $111.40 a barrel, up approximately 2.4%, while U.S. West Texas Intermediate (WTI) rose to about $99.30, gaining 2.2%, according to market figures reported by Anadolu Agency and Trading Economics.
The gains followed a series of attacks on Saudi infrastructure, increasing uncertainty over the security of energy facilities and shipping routes across the region.
Drone Attack Targets Saudi Oil Facility
Saudi authorities said air defenses intercepted a drone attempting to strike the Shaybah oil field on Wednesday. Falling debris killed two people and injured two others, while a vehicle caught fire outside the facility.
The Saudi Energy Ministry said the incident did not affect oil field operations, according to Reuters.
The attack occurred amid renewed strikes by Yemen’s Iran-aligned Houthi movement against Saudi infrastructure, including energy installations and airports.
Washington also ordered some diplomatic personnel and family members to leave Saudi Arabia as security concerns intensified.
Although the latest attack did not interrupt production at Shaybah, it reinforced concerns about the vulnerability of critical energy infrastructure during the continuing regional conflict.
Reports of Potential New Strikes on Iran
Geopolitical uncertainty increased following reports that the United States and Israel had developed plans for possible renewed military strikes against Iran after the U.S. midterm elections in November.
The New York Times reported the planning, citing U.S. officials and individuals familiar with the discussions.
The reported plans do not establish that new strikes have been authorized or will take place. Nevertheless, the possibility of further escalation has added uncertainty to oil markets already sensitive to developments involving Iran and its regional allies.
Any expansion of military operations could threaten energy production, shipping activity and transportation routes in the Persian Gulf.
Strait of Hormuz Remains Central to Supply Outlook
Despite the security concerns, crude oil shipments through the Strait of Hormuz have increased in recent weeks, approaching levels recorded before the conflict, according to Trading Economics.
The recovery in shipments could help limit further increases in oil prices, although refined petroleum product flows remain constrained.
Saudi Arabia’s crude exports increased 7.9% in August, reaching their highest level since March, providing an additional indication that some regional supply flows have recovered.
However, renewed attacks on tankers, ports or production facilities could quickly reverse those improvements.
The Strait of Hormuz remains a critical transportation corridor for global energy markets, making developments in the surrounding region particularly important for international oil prices.
Global Energy Markets Face Continued Volatility
The latest increase in crude prices reflects a combination of geopolitical risks and uncertainty about the stability of regional supplies.
Higher oil prices can raise transportation and manufacturing costs, increase pressure on consumer prices and complicate the inflation outlook for major economies.
For energy-importing countries, sustained increases in crude prices can also affect trade balances and economic growth.
The direction of oil prices will depend partly on whether attacks continue, whether regional export flows remain stable and whether diplomatic or military developments change expectations for future supply.
While the latest incident did not disrupt production at Shaybah, the market reaction illustrates how threats to energy infrastructure can influence prices even before measurable supply losses occur.
