At 8:00 a.m. on August 11, Chile local time, the Prillex plant of explosives supplier Enaex, located in Mejillones, Chile, officially commenced a lawful strike. A total of 89 union members participated in the strike and blockaded the plant entrance, temporarily disrupting traffic on nearby roads. The plant produces ammonium nitrate, an essential raw material for blasting agents used at copper mines in northern Chile. Enaex stated that it has taken measures to ensure client deliveries, and production is currently being maintained by non-striking employees and an emergency team.

Low-priced non-registered copper trades actively, while weak end-user demand suppresses SHFE copper premiums.
Looking ahead to tomorrow, with delivery approaching, the intermonth backwardation spread is expected to widen further. The cost of contract rollover for some suppliers will rise significantly, strengthening their willingness to sell spot copper and pushing quotes for standard-quality copper to quickly drop into discount territory. Meanwhile, amid relatively strong front-month contract prices, some deliverable material is inclined to be converted into warrants, resulting in divergent spot cargo flows. As of August 11, SHFE copper registered warrants stood at about 23,200 mt. As of the morning session close on August 12, open interest in the SHFE copper 2608 contract remained at about 23,000 lots. The pace of the pullback in open interest and changes in warrants ahead of delivery still warrants close attention. On the demand side, end-use consumption remained weak, with downstream procurement still largely need-based. Low-priced non-registered copper attracted active trading on the back of its price advantage, but this has yet to lead to a significant improvement in overall procurement. Overall, amid the widening backwardation spread, increased supplier willingness to sell, and weak end-use demand, quotes for Shanghai spot copper against the 2608 contract are expected to remain under pressure tomorrow, with spot copper likely staying at a discount.

[SMM Shanghai spot copper] Looking ahead to tomorrow, as delivery approaches and the inter-month backwardation spread widens further, the cost of rolling over positions for some suppliers has risen noticeably, boosting their willingness to sell spot cargoes, which has pushed mainstream standard-quality copper quotes quickly down to a discount range. Meanwhile, against the relatively strong front-month contract price, some deliverable material is being shifted to warrants, leading to a divergence in spot cargo flows. As of August 11, SHFE copper registered warrants stood at approximately 23,200 mt; as of the morning close on August 12, open interest in the SHFE copper 2608 contract remained around 23,000 lots. The pace of open interest pullback and warrant changes ahead of delivery still warrants close attention. On the demand side, end-use consumption remains sluggish, with downstream purchases still largely need-based, and low-priced non-registered copper trading relatively actively on price advantage but not yet driving a noticeable improvement in overall procurement. Taken together, with the widening backwardation spread, increased willingness to sell among suppliers, and weak end-use demand, spot copper prices against the SHFE 2608 contract are expected to remain under pressure tomorrow, and the spot is likely to stay at a discount.
