Copper prices fell on Thursday despite the tight supply.
Global exchange stocks, comprising those in LME, CME and Shanghai Futures Exchange warehouses, have fallen for the last two months.
They stood at a cumulative 232,550 tonnes at the end of October, down 30,000 tonnes since the start of 2021 and down almost 150,000 tonnes from October 2020. Shanghai stocks currently total less than 50,000 tonnes.
Copper for delivery in December fell 0.5% on the Comex market in New York, touching $4.30 per pound ($9,461 per tonne) on Thursday afternoon.
