LONDON – If there were any doubt that the zinc supply chain is tightening, it should be dispelled by this year’s benchmark smelter treatment charge. The treatment charge is the fee paid by a miner to a smelter for converting mined concentrates into refined metal and it is probably the best indicator of raw material availability; high during times of surplus and low during times of scarcity.
This year’s headline fee of $172 per ton is the lowest in a decade, a firm swing of the negotiating pendulum in favor of miners and a tangible sign that the much-anticipated concentrates crunch has arrived.
Indeed, miners have used the squeeze on availability to make what might turn out to be a historic change in how these annual benchmark contracts are structured. Zinc bulls have been waiting a long time for this supply squeeze and they may have to wait a bit longer before it moves from raw materials to refined metal parts of the chain.
