Global oil markets saw a sharp decline on Tuesday as officials signaled that diplomatic efforts to reopen the strategically vital Strait of Hormuz could bear fruit as early as this week. The price of Brent crude, the international benchmark, fell by nearly 5% to drop below $80 per barrel. Simultaneously, US West Texas Intermediate prices also slid by more than 5%, reaching $76 a barrel. Both benchmarks hit their lowest levels since July 13.
US Secretary of State Marco Rubio and Treasury Secretary Scott Bessent announced that discussions aimed at restoring shipping movement have progressed. Rubio confirmed that talks involving Iran and Oman have moved forward, though he cautioned that a final agreement has not yet been reached.
When asked about potential transit fees for ships, Rubio emphasized that the goal is to ensure freedom of movement. Iran, meanwhile, has maintained that it is not negotiating directly with the US, instead engaging with Oman as a mediator.
An Iranian foreign ministry spokesperson described these talks regarding a new mechanism for vessel transit as positive. Qatar, another key mediator, confirmed it remains committed to diplomatic efforts, though it noted no direct talks between Washington and Tehran are currently planned.
The Strait of Hormuz previously facilitated approximately one-fifth of the world's daily oil and liquefied natural gas supplies before the conflict began in late February. Since then, Iran has suspended most traffic through the waterway, while the US has maintained a naval blockade on Iranian ports.
The situation is further complicated by a separate blockade of Saudi ports in the Red Sea, enforced by Yemen’s Iran-backed Houthis since July 20.
This alternative route has become increasingly perilous, with a recent surge in maritime attacks. On Tuesday, the Indian shipping minister reported that an Indian-flagged vessel was sunk by a projectile near Yemeni waters, though all 14 crew members were successfully rescued.
Analysts describe the current risk to Middle Eastern shipping as the most severe since the start of the conflict. Danni Hewson, head of financial analysis at AJ Bell, noted that investors remain wary due to the fragility of previous negotiations. The ongoing instability has caused significant fluctuations, with prices surging above $120 during escalations and dropping whenever diplomatic breakthroughs appear possible.
While these price spikes have generated record profits for major energy firms like BP, Shell, Chevron, and Exxon Mobil, Hewson noted that these companies remain at the mercy of the broader political landscape.
The market volatility has had a direct impact on consumers worldwide. In the UK, the RAC motoring group reports that petrol costs have reached £1.60 per litre. In the United States, AAA data shows gasoline prices averaging above $4 per gallon, with diesel costs nearing $5.40.
President Donald Trump has previously stated he called off major strikes against Iran to allow for these diplomatic discussions, adding another layer of uncertainty to the market as investors monitor both geopolitical developments and broader economic indicators.
"There's been progress made in those talks, but not finality yet. We're hoping that will happen very shortly," he told reporters at the State Department.
Investors have experienced jitters on Wall Street as results from Big Tech firms indicate spending on the technology is set to continue to soar.
