September WTI crude oil futures posted their most significant weekly gain in several months, climbing above $80 per barrel after beginning the week near $72.50. The rally represented a sharp reversal from the previous two weeks, when market sentiment had been driven by expectations of improved oil flows through the Strait of Hormuz, which had weighed on prices. The renewed upward momentum reflected traders’ reassessment of geopolitical risk factors affecting global crude supplies.
The primary market catalyst emerged over the weekend when military confrontations between U.S. and Iranian forces escalated significantly. U.S. airstrikes targeted military facilities located near Iran’s southern coastal regions, prompting retaliatory Iranian missile and drone strikes against American positions throughout the area. These developments triggered heightened apprehension regarding potential disruptions to crude oil exports originating from the Persian Gulf region.
Iran’s stated intentions to potentially obstruct major shipping corridors added further to market concerns. The country threatened to interfere with transit through both the Strait of Hormuz and the Red Sea, with the latter threat potentially involving Houthi allied forces. Given that approximately one-fifth of globally traded seaborne crude oil passes through the Strait of Hormuz, market participants rapidly incorporated the possibility of supply constraints into their pricing calculations.
Additional support for crude prices came from newly released U.S. inventory statistics published by the Energy Information Administration. The data provided further reinforcement for the upward price trajectory established by the geopolitical developments during the period.
