Platts, part of S&P Global Commodity Insights, will launch eWindow instruments for the 7.8 RVP gasoline grades in Chicago as differentials against front-month NYMEX RBOB futures, effective June 2, following the implementation of a removed RVP waiver in six Midwest states earlier this year.

The addition of the new eWindow instruments follows previously announced changes to Platts Midwest gasoline assessments resulting from the RVP waiver removal. Following extensive consultation with the market, the changes to the assessments were announced on Dec. 30, 2024, in a subscriber note available here(opens in a new tab). The launch of related new assessments was announced on Feb. 3, 2025, in a note found here(opens in a new tab).
