Disruption in Oil Pricing Amid Strait of Hormuz Conflict

The Platts Dubai benchmark, which prices approximately 18 million barrels of oil per day—nearly 20% of global supply—faces significant challenges due to halted exports through the Strait of Hormuz. Despite U.S. claims that the strait is open, the reality remains that tanker traffic has slowed dramatically, leading to a disconnection between the benchmark and actual market conditions. In response, Platts has reduced the deliverable grades from five to two—Murban and Oman—resulting in a 40% decrease in the pricing basket's supply. Market participants have described the benchmark as "effectively broken," with many traders withdrawing from Dubai-linked transactions.

The pricing structure of the Platts Dubai benchmark has evolved, particularly influenced by TotalEnergies's trading activities, which saw the company dominate the market by acquiring 77 out of 82 cargoes in March. This concentration of trading raises concerns about competitiveness, as a limited number of transactions can allow a single entity to shape prices. Historically, Murban crude was priced at a premium due to its ease of processing, but recent supply dynamics have altered this relationship. OPEC+ production cuts have constrained the availability of heavier sour grades, making Murban more accessible and often the cheapest deliverable crude in the Dubai basket.

Refiners, especially in China, have invested heavily in upgrading capabilities, allowing them to process heavier, cheaper crudes while maximizing output of lighter products. This shift has diminished the structural advantages previously held by light sweet crudes like Murban, enabling refiners to substitute based on availability rather than quality. Consequently, the pricing behavior within the benchmarks has changed, with Murban increasingly becoming a pivotal factor in setting prices.

The conflict surrounding the Strait of Hormuz has led to significant disruptions, with Iran asserting tighter control over the strait following U.S. military actions. The immediate impact has been severe, with around 13 million barrels per day of oil supply trapped in the Gulf, forcing producers to shut down fields and refineries. Even if hostilities cease, restoring flows to pre-war levels is expected to take months or years due to logistical challenges, including tanker availability and the need to repair damaged infrastructure.

U.S. President Donald Trump has indicated that negotiations are ongoing, while also threatening military action if shipping disruptions continue. Meanwhile, analysts predict that even with a resolution, oil prices may not return to pre-war levels, with shortages of products like jet fuel and natural gas likely to persist.

Critics argue that the current pricing mechanisms are unsustainable and call for reforms to address the vulnerabilities exposed by the ongoing conflict. The concentration of trading power among a few entities raises concerns about market fairness and transparency, prompting calls for a reevaluation of the Dubai benchmark's structure.

As the situation evolves, the pace of recovery in oil flows will depend on diplomatic efforts between the U.S. and Iran, as well as logistical factors such as tanker insurance and freight rates. The International Energy Agency estimates that while some Gulf oil fields could return to pre-war output levels within weeks, others may face prolonged challenges due to infrastructure damage and low reservoir pressure.
