Fastmarkets invited feedback from the industry on the pricing methodology for its International Organization of Securities Commissions (IOSCO)-audited manganese ore indices, via an open consultation process between March 25 and April 27, 2026.

May 8, 2026

This consultation was done as part of Fastmarkets’ published annual methodology review process.

No feedback was received during the consultation period and therefore no changes will be made to the methodologies at this stage.

This consultation sought to ensure that our methodologies continue to reflect the physical market for our audited physical markets for steel scrap, in compliance with IOSCO’s principles for Price Reporting Agencies (PRAs). This includes all elements of our pricing process, our price specifications and publication frequency.
