Brent at $83.55 and WTI at $78.18 After 7 Percent Weekly Drop as Iran-Oman Corridor Progress Deflates Hormuz Premium

Brent crude settled at $83.55 per barrel Friday, down 7 percent on the week as Iran-Oman corridor talks trimmed Hormuz risk premium; WTI ended at $78.18.

Brent crude futures closed at $83.55 per barrel on Friday, August 7, per ICE Futures Europe, up 1.29 percent on the day but down more than 7 percent for the week. WTI settled at $78.18 per barrel on the same session, per CME Group, up 1.15 percent on Friday. The week's net decline reflects a rapid repricing of Hormuz disruption risk as diplomatic progress on an Iran-Oman shipping corridor trimmed the geopolitical premium embedded in crude futures since July.

From Above $100 to $79.45: The Week's Price Arc

Brent crossed above $100 per barrel as recently as July 23, driven by a near-total shutdown of Strait of Hormuz transits. Iran-Oman corridor negotiations then knocked Brent to $79.45 per barrel by Tuesday, August 5, a 20.6 percent decline from the July peak, as Oil Authority reported on August 5. Friday's recovery to $83.55 reflects a partial restoration of risk premium after ADNOC reported 15 separate vessel attacks in the region this week, per OilPrice.com. Brent ended the week $6.20 below its August 1 open, despite regaining ground on Thursday and Friday.

The Brent-WTI spread widened to $5.37 per barrel by Friday's close, above the $2 to $4 range typical in less disrupted markets. Brent carries more Hormuz-specific geopolitical content, while WTI responds more directly to domestic US inventory signals. An EIA report this week confirmed US commercial crude inventories rose 2.5 million barrels in the week ending July 31, a bearish signal that weighed on WTI without equivalent pressure on Brent.

Measuring the Residual Geopolitical Risk Premium

When the Iran-Oman corridor deal was announced on August 5 and Brent touched $79.45, that trough likely reflected a near-zero Hormuz disruption scenario priced into futures. Friday's settlement of $83.55 represents $4.10 per barrel above that floor. The market is pricing in a $4.10 residual risk that Hormuz shipping does not normalize as quickly as the corridor timeline suggests.

The framework requires a 30-day mine-clearing operation in the median lane before commercial traffic resumes, according to Oil Authority reporting from August 7. Hormuz vessel traffic stood at 33 transits across Monday through Thursday this week, compared with a pre-conflict baseline of 130 to 140 daily transits. At 3 to 4 percent of normal volume, any disruption to the corridor timeline would pull prices back toward the $100 level seen in late July.

Corridor Progress and Continued Attacks

ADNOC's report of 15 vessel attacks this week illustrates the central tension in the market. Diplomatic progress is advancing and geographic coordinates for the corridor lanes are agreed between Iran and Oman. Yet physical attacks on vessels continued through the week. The 30-day mine-clearing requirement creates a window in which the Hormuz risk premium cannot fully unwind regardless of diplomatic goodwill, because the physical hazard remains until removal is complete.

From Brent's July 23 high above $100 to the August 5 low of $79.45, the market extracted roughly $20 per barrel of geopolitical risk premium over three weeks. Since then, $4.10 per barrel has returned. Whether additional premium comes back depends on whether attack reports escalate, whether the mine-clearing schedule holds, and whether Iranian compliance with corridor terms is confirmed by independent observers.

What to Watch This Week

The EIA Weekly Petroleum Status Report covering the week ending August 8 publishes on Wednesday, August 12. A draw in US crude inventories would put upward pressure on WTI and narrow the Brent-WTI spread. A further build would widen it. On the geopolitical side, any confirmation that mine-clearing operations have begun in the Hormuz median lane would signal the corridor is on track and Qatari cargo flows could resume toward the end of August.
