Brent Surges to Four-Month High as U.S.-Iran Naval Standoff Near Hormuz Escalates
ICE Brent November surged 6.3% on Thursday (2026-09-10) to a four-month high of $107.60 amid intensifying U.S.-Iran naval standoffs near the Strait of Hormuz.
ICE Brent November crude settled at $107.60 a barrel on Thursday (2026-09-10), up 6.3% on the session, after touching an intraday high above $108, the highest in nearly four months according to Rigzone. The front-month contract stood at $104.32 as of Saturday (2026-09-12) morning. Weekly gains across the major contracts ran between 11% and 13%, the sharpest advance in nearly two months, Blockonomi reported.6,7
Maritime confrontations between U.S. and Iranian forces near the Strait of Hormuz intensified sharply during the week, Blockonomi reported. The intraday high of $109.97 was the highest Brent had reached since early May. Diplomatic discussions between Iran and other parties remained inconclusive.7
The mechanical buyers added momentum. Trend-following commodity trading advisers flipped to 100% maximum long positions, Rigzone reported, while algorithmic traders in WTI futures held a 91% net long stance. As prices pushed through technically significant levels, options dealers with short-gamma exposure were buying futures to hedge, layering additional pressure on top of a move that began with genuine supply disruption concerns.6
EIA weekly data showed distillate stockpiles rose 2.1 million barrels, yet supplies remained at the lowest seasonal level on record, Rigzone noted. That limits the inventory cushion refiners draw on when crude supply tightens.6
ICE Brent front-month has gained more than 75% in 2026, though at $104.32 it remains well short of the April wartime peak of $126 a barrel, reached when Hormuz transit disruptions were at their most severe and Persian Gulf producers were rerouting cargoes on longer alternative passages. The partial restoration of flows since April has contained the rebound.6
The Strait of Hormuz has not been the only pressure point. Around Wednesday (2026-07-22), Houthi rebels in Yemen threatened a maritime blockade on Saudi Arabia, opening a second front at the Bab el-Mandeb. An analyst at MarineTraffic said that same day that "the Bab el-Mandeb risk picture is deteriorating," referring to the waterway that forms the gateway to the Red Sea. By Thursday (2026-07-23), Houthis had claimed strikes on two Saudi oil tankers in the Red Sea, pushing front-month Brent for September delivery above $100 for the first time in nearly two months as traders priced simultaneous disruption risk at both chokepoints.1,3,2
That Thursday (2026-07-23) session closed front-month Brent at $100.69, up 7% on the day, while U.S. crude settled at $92.19, up 6.2% and at its highest close since June 4, NBC News reported. By that point, Brent had climbed roughly 20% in about two weeks as repeated attacks on commercial shipping, renewed fighting involving Iran and mounting export disruptions steadily erased expectations of a quick return to normal oil flows, oilprice.com reported.4,2
Prices retreated briefly. Around Thursday (2026-07-30), crude edged lower as investors weighed reports of progress in talks among the United States, Iran and Oman. Analysts said any confirmed peace agreement and Hormuz reopening could weigh on crude prices. No agreement emerged, and the subsequent rally more than covered that retreat.5
Goldman Sachs said in late July (2026-07-23) that it expected Brent to retain most of its summer gains, citing declining global inventories, lower Middle East production, seasonal travel demand and a slowdown in strategic petroleum reserve releases, RTE reported. Those supports have proved durable, and the latest Hormuz escalation has added fresh pressure to an already tight physical market.3
What crude prices have not yet fully reflected is a confirmed reduction in actual throughput at the strait itself. A market participant cited by Rigzone was direct: "In order to see prices moving significantly higher, we would need to see recent escalation feeding through to renewed disruptions in oil flows through the Strait of Hormuz." ICE Brent front-month at $104.32 as of Saturday (2026-09-12) has absorbed substantial geopolitical risk. Whether actual flows at Hormuz narrow over the coming sessions is the signal traders are watching.6
