Platts proposes launch of new USGC pipeline unleaded 87 segregated batch assessments, eWindow instrument

Platts, a part of S&P Global Energy, is proposing to launch new assessments for segregated batches loading onto Colonial Pipeline for US Gulf Coast unleaded 87 regular gasoline, effective July 13, 2026.

Platts would continue to assess prompt-cycle fungible batches for regular unleaded 87 (M2 grade) gasoline in the Platts Market on Close assessment process (MOC).

As part of this proposal, Platts would assess segregated batches, currently designated as 2M grade, as a differential to NYMEX RBOB futures, an outright price, and a spread to the fungible M2 assessment expressed in cents/gal.

Platts would also launch a related eWindow instrument to reflect segregated batches. The new instrument would be under the product name "Platts Gasoline 2M Seg" in the Platts eWindow.

In line with Colonial Pipeline rules, the minimum volume for segregated batch assessments would be 50,000 barrels.

Bids and offers in the MOC would be for a minimum volume of 50,000 barrels and could be increased in 50,000-barrel increments. Similar to other US gasoline eWindow instruments, participants would be able to improve their bids or offers by 0.25 cent every 30 seconds and would have the option to repeat their bid or offer in the event of a trade.

The minimum volume considered for Platts unleaded 87 regular gasoline fungible assessments (PGACT00) would not be impacted by this change and would remain 25,000 barrels.

From July 13, the Platts Gasoline M2 eWindow instrument would strictly reflect fungible batches for Colonial Pipeline's prompt cycle

FOB USGC Waterborne unleaded 87 and swap assessments would reflect the fungible unleaded 87 assessment as the basis for the calculations.

The new segregated batch price assessments would be published on Platts Global Alert and Platts Refined Products Alert pages 28, 156, and 330, as well as in US Marketscan and the Oilgram Price Report.
