Conclusion of Fastmarkets’ open consultation on IOSCO-audited non-ferrous price assessments, indices

Fastmarkets opened a consultation on October 1, inviting feedback on its IOSCO-audited non-ferrous materials methodologies in line with our annual methodology review process.

The consultation, which closed on October 31, sought to ensure that the specifications and methodology for our audited alumina, aluminium, cobalt, copper, lithium and manganese ore prices continue to reflect the physical market. This includes all elements of our pricing process, our price specifications and the publication frequency.
Full details of the prices covered by this consultation can be found via at this link.
No new comment or feedback was received by October 31 suggesting that any immediate material change was required to the existing methodologies, with one exception related to alumina pricing.
Fastmarkets has therefore decided to extend the consultation period on its alumina indices methodology until December 3 to invite further industry feedback. A separate notice on this can be found here. No further consultation on any other IOSCO-audited prices is open at this stage.
Following a consultation, Fastmarkets has also since confirmed that, from Wednesday December 1, it will publish its seaborne Asia battery-grade lithium carbonate and hydroxide assessments on a daily basis.
Fastmarkets invites feedback on a continuing basis throughout the year. To provide comment or feedback on the content of the Iosco-audited non-ferrous methodologies, or if you would like to provide price information by becoming a data submitter to these prices or indices, please email
