Oil prices fell to a three-week low on Tuesday, August 4th, 2026, following announcements by senior US officials that talks with Iran have advanced toward reopening the Strait of Hormuz, a critical shipping route for global oil supplies.

US Secretary of State Marco Rubio and Treasury Secretary Scott Bessent both confirmed that discussions had progressed to potentially allow shipments to resume as soon as this week. Rubio noted progress in talks involving Iran and Oman to increase the passage of ships through the strait.

The cost of Brent crude, the global benchmark for oil prices, dropped by nearly 5% to below $80 (£60) per barrel. Similarly, US West Texas Intermediate prices fell more than 5% to $76 a barrel. This decline reflects hopes that supply disruptions could ease amid the conflict between the US and Iran.

However, the failure of previous negotiations to de-escalate tensions has contributed to a volatile oil market, impacting fuel prices worldwide. In the UK, petrol prices have returned to levels seen at the start of the conflict, with an average cost of £1.60 per litre, according to the RAC motoring group. In the US, gasoline prices remain above $4 per gallon, as reported by the AAA.

Adding to regional tensions, a projectile sank an Indian-flagged vessel near Yemeni waters on Tuesday, though all 14 crew members were rescued, according to India's shipping minister.

Danni Hewson, head of financial analysis at AJ Bell, commented, "Investors are acutely aware of how many times we've already been at this point in the war and how fragile the process of securing lasting agreements can be."

The developments come amid ongoing uncertainty, with officials hopeful that a deal to normalize shipping through the Strait of Hormuz may be reached imminently.
