Amendment to UG2/MG chrome ore index

Fastmarkets will amend the baseline chrome to iron ratio in its MB-CHO-0003 chrome ore South Africa UG2/MG concentrates index, cif China as of the calculation on Tuesday November 14.

After a consultation, which closed on Thursday November 2, along with data examination, Fastmarkets will amend the base chrome to iron ratio in its chrome ore South Africa UG2/MG concentrates index, cif China to 1.3:1, from 1.27:1.

In the calculation of the index, if price data is received for material with chrome to iron ratios different from that of the index basis, this is normalized using in-house developed models based on regression analysis.

The change in the base chrome to iron ratio is aimed at increasing the predictability of the index calculation by helping to reduce the degree of normalization required to adjust prices for the most liquid products to the index base specification.

Fastmarkets will not proceed with the proposal to expand the range of ratios accepted to include 1.37:1 on the upper end, from 1.35:1 currently, because of a lack of clear support.

The changes to the specification will be as follows:

MB-CHO-0003 Chrome ore South Africa UG2/MG concentrates index, cif China, $/tonne
