Global oil prices edged higher on Wednesday, driven by mounting concerns over supply chain disruptions in the Middle East. Traders are increasingly wary as attacks on maritime vessels continue to expand beyond the traditional flashpoints of the Strait of Hormuz, raising significant risks for shipping lanes and critical energy infrastructure.
As of 0022 GMT, Brent crude futures saw an increase of 85 cents, or 0.78%, reaching $109.64 per barrel. Similarly, U.S. West Texas Intermediate (WTI) crude rose by 76 cents, also marking a 0.78% gain to trade at $98.58 per barrel. This upward movement follows a volatile trading session on Tuesday, where Brent crude had previously settled lower at $108.79 after hitting a five-month peak of $111.99.
The security situation at sea has deteriorated, with a supertanker reportedly catching fire after striking a sea mine south of the Strait of Hormuz. Iran’s Revolutionary Guards Navy claimed the vessel was “violating” Iranian regulations. According to data provided by the shiptracker Kpler, there have been at least 18 attacks on vessels reported over the past two weeks, indicating a growing threat to global energy transit.
Analysts at LSEG noted that the targeting of vessels has moved as far south as the Gulf of Oman, which complicates loadings outside of the Arab Gulf. These attacks also threaten ship-to-ship transfers that have been essential in supporting Middle East supply volumes as regional conflicts persist. In addition to maritime risks, the Houthis claimed responsibility for attacks on a Saudi Aramco site in Yanbu, the Shaybah oilfield, and airports in Riyadh and Abha.
Efforts to de-escalate the situation have so far yielded limited progress. Iranian Foreign Minister Abbas Araqchi stated in a recent television interview that Iran has not received any response from Saudi Arabia or the Houthi forces regarding its offer to help broker peace talks. Meanwhile, internal conflict in Yemen has also intensified, with the death toll from a Houthi attack on government forces rising to 73 earlier this week.
The current market environment is further complicated by challenges in the domestic U.S. energy sector. Officials from the U.S. Department of Energy confirmed they are actively working with refiners globally to boost fuel output, as ongoing diesel shortages continue to exert upward pressure on prices. Additionally, an extended Reuters poll suggested that crude oil stockpiles likely fell by approximately 800,000 barrels in the week ended October 16, adding further supply-side strain.
Investors remain focused on whether diplomatic mediation might offer a path to stability. Price volatility has been evident, with markets previously dipping when Iran’s president discussed potential mediation efforts during a meeting with Pakistan's army chief in Tehran. However, the lack of a tangible breakthrough, combined with the escalation of tactical military incidents, keeps the market outlook highly sensitive to regional developments.
Moving forward, the primary concern for the energy market remains the security of critical transit corridors and oil installations. As analysts and traders monitor the frequency and geographical reach of maritime incidents, the persistence of these regional risks is expected to continue influencing global crude pricing. Market participants are also keeping a close watch on U.S. inventory data, as supply-demand imbalances in the product market could further exacerbate the current price pressures.
