SUBSCRIBER NOTE: Platts proposes to amend assessment methodology for Suez Blend, Syrian Light, Syrian Heavy, Es Sider

Following an extended period of low liquidity for the crude oil grades Suez Blend, Syrian Light and Syrian Heavy (also known as Souedie), Platts is proposing to amend the methodology behind these assessments, as well as that for Es Sider, to maintain their accuracy in the event of market liquidity failing to recover.

Platts currently states for all four grades that in periods of spot market illiquidity the price assessments will be valued as a differential to the Mediterranean sour crude benchmark, Urals CIF Med, taking into account the quality difference between the crudes.

Given the differences in market dynamics and grade quality between the grades and Urals, Platts is proposing to amend this methodology to allow them to be assessed by comparison to other relevant crude oil grades, as well as to other important indicators such as refinery margins.

Platts also proposes that the methodology guide for Libya's Es-Sider be amended to read: "In periods of spot market illiquidity, Es Sider may be valued by comparison to other relevant crude oil grades, as well as to other important indicators such as refinery margins, netbacked where necessary to Es Sider using relevant freight rates as published in Platts Dirty Tankerwire."

No other changes to the four assessments are proposed.
