Platts to launch new FOB Arab Gulf (Inside Strait) spot differential assessments April 1, maintain existing FOB Arab Gulf differentials

  • Platts to launch additional Inside Strait spot differential assessments reflecting value of refined products at ports inside the Strait of Hormuz
  • Existing FOB Arab Gulf differential assessments are maintained, will reflect loadings from the Gulf of Oman
  • Platts continues to seek feedback on the methodology of existing FOB Arab Gulf differentials
  • MOPAG netback assessments methodology remains unaffected

Platts, part of S&P Global Energy, will publish 9 new FOB Arab Gulf (Inside Strait) spot differential assessments for clean refined products -- including naphtha, gasoline, gasoil, and jet fuel -- effective April 1, 2026, amid continued disruption to shipping operations through the Strait of Hormuz.

Meanwhile, Platts will maintain its existing suite of FOB Arab Gulf differential assessments to reflect loadings outside of the Strait of Hormuz.

This follows market feedback to a consultation published March 20, which sought immediate feedback on the deliverability of clean refined products loading at Middle East ports outside the Strait of Hormuz, as well as on the FOB AG spot differential assessment methodology approach in the event of sustained disruption to loading operations outside the Strait. This decision follows market feedback gathered around differences in market values between refined products traded for loading inside the Strait of Hormuz, relative to outside the Strait of Hormuz.

Platts continues to consult on the underlying methodology for the existing FOB Arab Gulf differentials, including methodology approaches in the event of further market disruption.

FOB Arab Gulf (Inside Strait) spot differential assessments

Effective April 1, Platts will launch nine new daily FOB Arab Gulf (Inside Strait) spot differential assessments for naphtha, gasoline, jet/kerosene, and gasoil, as well as their respective monthly averages. These assessments will be published as spot market premiums/discounts to Platts established benchmark MOPAG netback assessments, and reflect the value of cargoes for loading 20-40 days forward from the date of publication.

In the absence of observable market activity for cargoes loading from Inside Strait ports, Platts may default to using editorial judgment based on all available information, including reference to historical assessments and spreads.

The new FOB Arab Gulf (Inside Strait) assessments will reflect the same specifications and terms as the existing FOB Arab Gulf differentials.

These assessments are intended to support market participants in valuing cargoes currently stored within inside Strait terminals and provide an interim reference point for parties engaged in extended long-term contract negotiations.

Existing FOB Arab Gulf spot differentials

The existing suite of FOB Arab Gulf spot differential assessments for naphtha, gasoline, gasoil, and jet fuel will reflect loadings at safe ports in the Gulf of Oman, including Fujairah, Sohar, and Duqm. These assessments will maintain their current specifications and terms and continue to represent tradable levels of the marginal barrel outside the Strait of Hormuz.

Platts continues to seek feedback on the March 20 consultation and may look at data from related markets when no direct market data is observed.

TIMESTAMP: All price assessments will reflect the tradable value of these markets at 12:30 pm Dubai time. This timestamp will align the new assessments with the respective netback values that Platts already publishes in the Middle East, corresponding to the 4:30 pm Market on Close timestamp in Singapore.

MOPAG NETBACKS : Platts Arab Gulf netback assessments (MOPAG) for the Middle East derive their values from the price assessments at the regional trading hub of Singapore (and Japan for naphtha) after adjusting for shipping costs. The launch of the new FOB Arab Gulf (Inside Strait) differential assessments will not affect these netback values, which Platts is committed to continuing to publish.

The new FOB Arab Gulf (Inside Strait) assessments will appear in the Platts Asia Pacific/Arab Gulf Marketscan and on Platts Global Alert pages 2004, 2018, 2302, 2304, 2320, 2402, 2420, and 2404. The monthly averages will appear on Platts Global Alert pages 2005, 2019, 2303, 2305, 2321, 2403, 2405, and 2421.
