BHP's Escondida, the world's largest copper mine, has reached a deal with its supervisors' union that averts a strike, easing one supply worry in Chile. Copper slipped 0.6% in New York after the news.
At a glance
- Copper settled at $14,490.50 a ton in New York, down 0.6%.
- Two unions at Antofagasta's Centinela mine have been on strike for about a week.
- Chile had its worst month for copper output in more than 15 years in August.
Background
Escondida, operated by BHP in northern Chile, is the world's largest copper mine. Its supervisors negotiate their own labour contract, and they had voted 95% to authorise a strike before mediation broke down this week. Near-record copper prices have encouraged workers across Chile to seek a bigger share of mining profits.
What happened
BHP and the supervisors' union at Escondida reached a deal that averts a strike, Reuters and Bloomberg reported on Wednesday. The union had said a day earlier that mediation had failed and that it would walk out.
Copper slipped on the news. It settled 0.6% lower at $14,490.50 a ton in New York, Bloomberg reported, and zinc, nickel and aluminium also fell.
Why it matters
A stoppage at Escondida would have added to a difficult year for Chilean supply. Production has been hit by labour actions and weather, and in August Chile had its worst month for copper output in more than 15 years.
Other risks remain. Two unions at Antofagasta's Centinela mine have been on strike for about a week, and copper is still close to the record near $14,900 it reached last month.
What it means
The deal removes one of the biggest near-term supply threats, which helps explain the dip in prices. But the market is still tight: Europe's top smelter Aurubis said large shipments of copper to the US have left warehouses elsewhere quite empty.
Interest rates are another headwind. US consumer prices rose at their fastest pace in five months in September, and New York Fed President John Williams said he still sees one more rate hike as appropriate this year.
Our read
Outlook: bearish. Averting a strike at the world's largest mine removes a major supply risk. Tight inventories and the Centinela strike still support prices.
What to watch
- Whether the Escondida agreement is formally ratified.
- Progress in talks to end the strike at Antofagasta's Centinela mine.
- US interest rate decisions, which affect demand for metals.
