Platts to launch US Midwest Aluminum Transaction Premium on PlattsView March 17

Platts, part of S&P Global Energy, will launch the PlattsView market communication tool for its US Midwest Aluminum Transaction Premium (MMAKE00) Platts Market on Close assessment process on March 17, 2026.

Reviewed participants in the MOC will be able to submit bids, offers and trades for publication directly through the PlattsView communication tool or through an editor, who would then publish the information using the software.

The PlattsView instruments to be launched for the US Midwest Aluminum Transaction Premium MOC process will be P1020 Aluminum Net- 30 DDP US Midwest and P1020 Aluminum Net- Cash DDP US Midwest, respectively, for delivery via truck or rail seven to 30 days forward from the day of publication.

Market participants will have the ability to price their bid or offer as a premium over LME Cash over the period coinciding with seven to 30 days forward. Bids or offers should reflect a minimum of 100 metric ton to a maximum of 1,000 mt in 20-mt increments.

Platts US Midwest Aluminum Transaction Premium assessment reflects delivery duty paid (DDP) to a typical freight consumer in a broad US Midwest region via truck or rail. Platts will publish bids or offers that reflect delivery to the list of US Midwest average-freight locations as per established methodology , accessible here.

The PlattsView instruments will generate a different format for headlines of bids, offers and trades published on Platts Metals Alert and via other Platts services.

Timing:

All bids and offers will continue to have to be submitted prior to 15.00.00 Eastern time.

Following any trade, market participants will have 5 minutes to rebid or re-offer.

No price changes are allowed from 15:55:00 to the close of the MOC at 16.00.00 Eastern time.

A rebid or re-offer, following a trade, in the last 60 seconds prior to the close of the MOC will trigger a 120-second extension from 16.00.01 to 16.02.00, in order to fully test the repeatability of the rebid or re-offer with the wider market.

Incrementability:

Bids and offers can be improved by a maximum of 0.25 cents/pound and a minimum of 0.05 cents/lb every 5 minutes.

As per Platts editorial guidelines, buyers or sellers can withdraw bids and offers at any time when communicating through PlattsView, provided no prior interest to transact has been expressed by any potential counterparty.

All bids and offers are firm from the moment submitted into PlattsView to the moment they are traded or the market close, unless the bid or offer is withdrawn from the software by the trader or a Platts editor.

Market participants may still report transparent named bids and offers directly to a Platts editor for publication via PlattsView.

The PlattsView timer will be used to determine the correct sequence of events when a bid or offer is amended, withdrawn, or traded by an interested counterparty.

Bids or offers submitted by email, or any other medium, such as instant messaging software, shall be measured at the time the bid, offer or trade indication is actually transmitted through the PlattsView software via the editor.

Guidelines:

Guidelines for the publication of bids and offers in the Platts Metals MOC are published on its online specification guide, available here.

Full information relevant to these assessments can be found in the Platts Global Nonferrous Metals specifications guide available here.

Platts expects credit relationships that prevail inside its assessment environment to fully reflect relationships in the market as a whole.

PlattsView provides direct entry and management of credit filters, which should mirror those normally applied in the marketplace.

Where Platts editors publish bids and offers on behalf of a company that submits data to an editor, counterparty credit settings are set to 'open' for reviewed participants in the assessment process unless companies have notified Platts in advance of any credit restrictions.

If a counterparty submitting information through an editor has not already notified Platts of any counterparty credit restrictions, it should notify Platts at least one hour prior to the price submission cut-off timing of 15.00.00 Eastern time if any counterparty credit filters need to be modified.
