Pre-Market Briefing — Tuesday, Aug 11, 2026

1. Overnight Hormuz Activity

Shipping activity in the Strait of Hormuz has reached a critical inflection point as the blockade enters its 163rd day. According to Gulf shipping traffic via Strait of Hormuz falls to six vessels, commercial traffic through the maritime choke point fell to just six vessels on Monday, August 10. This represents a significant decline from the 10-day average of 11 vessels and is a fraction of the pre-crisis baseline of 73 transits per day Strait of Hormuz Status: August 11, 2026 | Straits Daily Brief.

On the ground, the situation remains tense as Iran's Foreign Ministry declared that the strait will not reopen until the United States lifts its naval blockade and "corrects" its behavior Iran says Strait of Hormuz won't open until the U.S. "corrects" behavior. Currently, 239 vessels are holding position away from berth in the region, excluding those within 25 kilometers of working ports Strait of Hormuz Status: August 11, 2026 | Straits Daily Brief. The physical transit deviation remains the primary contributor to the "extreme" band rating on the Hormuz Index Crisis Pressure composite.

2. Asian Session Oil Moves

Brent crude futures surged to $89.73 per barrel, a 6.33% increase over the last 24 hours Strait of Hormuz Status: August 11, 2026 | Straits Daily Brief.

The primary catalyst for this rally was the introduction of new, sweeping demands by President Donald Trump. The U.S. administration has signaled it will now require financial compensation from Iran as a prerequisite for continuing peace talks Oil Holds Three-Day Gain as Trump Demands Cloud Hormuz Outlook. This move has effectively extinguished near-term hopes for a diplomatic resolution that seemed possible last week when Iranian and Omani negotiators were finalizing a draft deal Iran and the US say a deal on the Strait of Hormuz is near.

3. Three Things to Watch at the US Open

1. The "Compensation" Deadlock: Markets will closely monitor any response from Tehran regarding President Trump's demand for compensation. If Iran views this as a non-starter, the geopolitical risk premium—which had briefly compressed on news of Omani mediation—is likely to expand further toward the $95 Brent level August 10, 2026 — Trump says he would require compensation from Iran as condition for talks | CNN.

2. EIA Inventory and Forward Curves: Traders are shifting focus to weekly EIA inventory data to gauge the impact of the prolonged Hormuz closure on domestic stockpiles. Analysts suggest that without a resolution, the forward curve could see accelerated moves toward $65–$70 averages only if a breakthrough occurs by late 2026; otherwise, the current spot premium will persist What will WTI Crude Oil (WTI) hit in August 2026? - Polymarket.

3. Logistics and Insurance Surcharges: With war risk insurance effectively canceled for Gulf transits since March, any further drop in the vessel count (currently at 6) could signal a total cessation of commercial traffic.
