Amendment to US HRC index methodology

Fastmarkets is changing the way it calculates its daily hot-rolled coil index, fob mill US, to align its methodology with other Fastmarkets indices.

Effective Monday October 31, the US HRC index will employ a two sub-index approach, categorizing and weighing inputs simply as sellers and buyers.

This marks the end of the 90-day consultation period that began on Thursday July 21.

Fastmarkets does not expect this change to materially affect the daily published price, based on internal analysis.
