El cobre del COMEX se dispara, el del LME baja; los diferenciales se amplían en medio de la incertidumbre sobre el arancel de la Sección 232.

Chilean miner AMSA and some core copper smelters in China finalised the pricing scheme for mid-year long-term contract copper concentrate TCs on July 1, abandoning the traditional fixed TC model for the first time and switching to a floor-index-linked pricing mechanism. It is reported that, as spot copper concentrate TCs had been consistently hitting historic lows, this brought multiple divergences to the mid-year long-term contract negotiations. China’s smelters have historically used fixed TCs for mid-year long-term contracts, but AMSA insisted on switching to index-based pricing this time, and ultimately the two sides reached an innovative compromise.
