Middle East Oil Pricing Is Cracking Under Pressure

Key Points:

• The Platts Dubai benchmark, which prices nearly a fifth of global oil supply, is under severe strain due to halted exports through the Strait of Hormuz, disrupting tanker traffic and disconnecting the benchmark from physical oil flows.
• Platts has reduced deliverable crude grades from five to two (Murban and Oman), cutting supply in the pricing basket by about 40%, leading market participants to describe the benchmark as "effectively broken" and prompting some Asian buyers to shift to alternative pricing methods.
• Murban crude has taken on a dominant role within the benchmark as medium and heavy sour grades become scarce due to OPEC+ production cuts, causing a historic inversion where Murban sometimes trades below sour grades, reflecting supply dynamics rather than quality.
• Refinery upgrades in Asia, especially in China, have lessened the traditional premium for light sweet crudes like Murban by enabling processing of heavier sour grades, altering long-standing pricing relationships and forcing Platts to adjust its benchmark methodology.
• Platts introduced a Murban Quality Adjustment in January to allow flexible pricing within the basket but suspended negative adjustments in March amid the Iran war to maintain supply flow, highlighting ongoing challenges in maintaining a reliable and competitive Middle East oil benchmark.
