Proposal to increase frequency of Shanghai equivalent-grade copper cathode premium

Fastmarkets invites feedback on a proposal to increase the publication frequency of the MB-CU-0412 non-exchange-deliverable equivalent-grade (EQ) copper cathode premium, cif Shanghai to twice weekly.

Fastmarkets, which currently assesses the premium every Tuesday, proposes to publish the Shanghai EQ copper cathode premium every Tuesday and Friday.

Fastmarkets began to track the Shanghai EQ copper cathode market in November 2019, and increased its assessment frequency from fortnightly to weekly in July 2023 following increased market interest.

This proposal to increase the pricing frequency to twice weekly will bring more market transparency amid continually rising demand and increased spot liquidity.

The proposed specifications for the premium will be as follows (proposed change in italics):
