The derived prices are:
MB-CU-0508 copper concentrates TC implied smelters purchase
MB-CU-0509 copper concentrates TC implied traders purchase
MB-CU-0510 copper concentrates RC implied smelters purchase
MB-CU-0511 copper concentrates RC implied traders purchase
.

These numbers will be derived from the MB-CU-0287 copper concentrates TC index, cif Asia Pacific, and the MB-CU-0288 copper concentrates RC index, cif Asia-Pacific, which price the mid-point of the market every Friday, and from the MB-CU-0422 copper concentrates counterparty spread, a coefficient updated at the end of every month to reflect the gap between smelter and trader purchases.

Fastmarkets’ index methodology screens outliers and applies a quantity-weighted model to ensure that the copper concentrate index is the most robust in the industry. Fastmarkets has no financial interest in the level or direction of the index.

Specifications for the implied prices, listed below, are consistent with the TC/RC index and the coefficients of counterparty spread and copper value-in-use.
