September WTI crude oil futures were trading at $84.12 late Thursday, down $6.35, or 7.02% for the week. With Friday's session still ahead, the weekly result is not yet final. However, the week's dominant narrative is clear: crude sold off sharply when traders believed diplomacy could restore a workable transit route through the Strait of Hormuz, then partially rebuilt the risk premium when military escalation resumed.

The Strait of Hormuz, located between Oman and Iran, is one of the world's most critical energy chokepoints, through which roughly a fifth of global oil consumption transits daily. Any disruption to shipping lanes there carries significant implications for global energy supply. The strait also handles significant volumes of Qatari liquefied natural gas, meaning any closure or disruption would affect both oil and natural gas markets simultaneously.

The week opened with Washington's pause in military strikes and Oman's proposal for a regional management framework for Hormuz. That development gave traders a concrete catalyst to sell crude. If the shipping route could reopen under an arrangement accepted by both Tehran and the Gulf states, the current supply disruption would be reclassified as a temporary shock rather than a lasting constraint. WTI came under heavy pressure as that possibility gained traction in the market. The price reaction underscored how sensitive crude valuations are to geopolitical narrative shifts: market participants moved rapidly from pricing a prolonged disruption scenario to discounting it, even though no physical shipping data had confirmed a return to normal tanker traffic.

That optimistic trade broke down quickly. Iran rejected the Oman plan and launched missiles at U.S. forces. The United States and Saudi Arabia struck Iran-backed groups in Iraq, and U.S. Central Command followed with attacks on Revolutionary Guard targets inside Iran early Thursday.

The reversal demonstrated that the earlier selling was built on diplomatic hope rather than an actual restoration of crude flows. The risk premium returned, but it has not recovered all the ground lost earlier in the week, leaving WTI sharply lower week to date even after the conflict moved back to the center of the trade. The partial recovery suggests the market continues to assign a meaningful probability to eventual de-escalation, even as the immediate security picture deteriorates. Historical precedent from prior Hormuz tensions—including incidents during the Iran-Iraq War in the 1980s and periodic confrontations since—shows that the chokepoint has rarely been fully closed, but even brief disruptions have triggered sharp price spikes followed by equally rapid declines once shipping resumed.
