Platts to discontinue Chicago Unleaded 87, 89 assessments

S&P Global Platts will discontinue its Chicago Unleaded 87 and Unleaded 89 gasoline assessments, effective June 1, 2021.

Platts understands there is limited spot market liquidity for regular and mid-grade unleaded gasoline, as the finished grades are no longer used in the Chicago gasoline market, which has switched primarily to CBOB or RBOB blends over the years as part of the US federal Renewable Fuel Standard program.

The assessments affected by this decision are as follows:

These assessments appear on Platts Global Alert pages 160 and 320, and also in Platts US Marketscan and Platts Oilgram Price Report, and in the Platts price database under the codes above.

Platts proposed discontinuing the Chicago Unleaded 87 and Unleaded 89 gasoline assessments in a subscriber note published Jan. 29, 2021: https://www.spglobal.com/platts/en/our-methodology/subscriber-notes/012921-platts-proposes-to-discontinue-chicago-unleaded-87-and-unleaded-89-assessments

Platts will continue to assess CBOB, RBOB, PBOB and Premium 91 in the Chicago pipeline market, as well as CBOB and RBOB in the Chicago BCX market and CBOB on the Wolverine pipeline.

Platts would like to clarify that its Chicago Premium 91 gasoline assessment (PPASQ00) reflects Premium CBOB (also known as P91) with octane of minimum 91, lead of maximum 0.01 g/gallon, and gravity of 62 API.
