Chile's Q3 Copper Output Hits Lowest in Over 20 Years, Full Year May Be Worst in Decades
nashnova research
Chile's Q3 copper output fell to 1.16 million metric tons, down 12% year-on-year — the lowest quarterly figure since late 2006. The world's largest copper producer is tightening global supply just as electrification demand accelerates.
How steep was the Q3 drop?
Chile's national statistics agency (INE) data shows Q3 copper output totalled 1.16 million metric tons, down 12% year-on-year and 8.7% quarter-on-quarter.
That is the lowest quarterly output on record since late 2006.
This means → Chile's mines are not wobbling slightly; they have hit a production gap not seen in nearly two decades.
Why did output fall so sharply?
Three forces combined: frequent accidents, extreme weather, and steadily declining ore grades.
In plain terms = mines shut down after accidents, bad weather disrupts operations, and the copper content underground keeps dropping year after year — all three hit at once.
Ore-grade decline is a long-term trend: the same volume of rock yields less copper over time, and that cannot be quickly reversed.
How bad could the full year get?
Year-to-date output through Q3 is down 8.6% versus the same period last year.
At this pace, Chile's 2026 full-year copper output could mark the worst in decades.
This means → it is not a one-quarter accident but a systematic weakening across the entire year.
What does this mean for global copper?
Chile accounts for more than one-fifth of the world's mined copper — it is the largest producer.
This reflects pressure building on both sides: supply is tightening as Chile produces less, while demand is accelerating as electrification — electric vehicles, grid upgrades — consumes more copper.
In plain terms = the world's biggest copper tap is running slower, and the queue of users is growing longer — the supply-demand gap could widen further.
