Platts launches US Aluminum Midwest Premium forward curve
Platts, part of S&P Global Energy, has launched a daily forward curve reflecting assessments of P1020 aluminum financial derivatives settling against the Platts Aluminum P1020 Transaction Premium delivered US Midwest benchmark (MMAKE00), effective Jan. 2, 2026.
New derivative assessments for Months 1-5
Platts' new daily derivative assessments reflecting a quantity specification of 25 metric ton lot size are published for Month 1, Month 2, Month 3, Month 4 and Month 5, along with related monthly averages. Platts also amended and renamed the prior six-month premium assessment (MMANJ04) to reflect a daily derivative assessment for Month 6, from the previous weekly (Thursday) cadence. The new Month 6, named MW US Transaction Premium Financial Mo06, reflects a quantity specification of 25-mt lot size.

The US Midwest Premium derivatives assessments are based on bids, offers or trades seen during the Platts Market on the Close assessment process. In the absence of any bids, offers or trades in the MOC, information from derivative exchanges, brokers or heard in over-the-counter markets may be taken into consideration.
Price information reflecting forward curve bids, offers and trades is reported in real time throughout the day on Platts electronic information service, Platts Metals Alert (PMA), along with other relevant market information.
The forward premium assessments for Month 1, Month 2 and Month 3, as well as related monthly averages, are published in Metals Daily and Metals Week, and on the PMA413 and MTL413 fixed pages. Forward premium assessments for all assessment months (Months 1-6) and related monthly averages and $/mt conversions are available in the Platts pricing database, as well as Platts Risk Market Data packages.
The assessments follow the Platts US holiday calendar and reflect a 4 pm US ET timestamp.
Platts previously proposed the new assessments in a subscriber note published Nov. 20, and announced its decision in a subscriber note published Dec. 5, available here.
