Physical crude oil cargoes have fallen into steep discounts across global markets as a surge in Middle Eastern supply changes the prompt market dynamic. The increase in available barrels follows a 60-day interim agreement between the U.S. and Iran intended to end the conflict that began on February 28. That accord has produced a temporary easing of U.S. sanctions and permitted some shipping to resume through the Strait of Hormuz - the narrow waterway through which about one fifth of global oil and liquefied natural gas shipments moved before the conflict.
As Tehran moves to ramp up exports and seeks buyers beyond China under the temporary sanction relief, physical crude benchmarks that had traded at premiums are now under pressure. When the war began and transit through the strait was effectively halted, many crude grades traded at record premiums because of concerns about constrained supplies. The re-entry of cargoes previously stranded in the Gulf, combined with a flood of offers from Abu Dhabi National Oil Co, Kuwait Petroleum Corp and Iraq's SOMO, has bolstered prompt availability.
The additional Middle Eastern barrels have pushed regional markers - Dubai, Oman and Murban - into discount territory. That change in pricing dynamics is reflected in activity across Asian markets, where refiners that commonly secure crude two months ahead have already booked shipments for delivery as far forward as August.
Meanwhile, U.S. crude exports to Asia are expected to ease in the third quarter after reaching a record high in May. Ship tracking data from Kpler showed U.S. shipments to Asia hit 2.634 million barrels per day in May, a peak that market participants now expect will moderate as Middle Eastern barrels increase prompt availability.
The widening of discounts is not limited to Middle Eastern benchmarks. European and West African grades have also seen their discounts widen during the same period, reflecting the broader effect of increased Gulf supply on global cargo valuations.
The market reaction observed to date stems from the temporary relief in shipping and sanction constraints created by the 60-day interim deal. The movement of previously stranded cargoes and fresh offers from major Gulf producers are the primary drivers cited for the shift from premiums to discounts across multiple benchmarks and grades.
