Chile Copper Output Hits Worst Q2 Since 2007

Chile

Chile copper output slumped to 1.27 million metric tons in the second quarter, a 7.7% year-on-year decline that marks the country’s weakest April-June performance since 2007, according to data stretching back nearly two decades. The drop highlights how persistent mine-grade deterioration and operational woes at state-owned Codelco and major private producers are choking supply from the world’s biggest copper supplier.

Codelco’s Struggle Deepens Across Key Mines

State giant Codelco remains at the center of the downturn. An internal company document indicated that El Teniente’s 2025 output fell 13% to 310,100 tons, and the decline accelerated into 2026. In the first quarter, Codelco’s total production reached just 272,000 tons, down 8.1% year-on-year, according to industry summaries using Cochilco data.

The weakness was widespread across Codelco’s portfolio. El Teniente recorded a 26% drop, Chuquicamata fell 18%, Gabriela Mistral declined 14%, Ministro Hales slipped 10%, and Andina was down 6%. Reuters reported in January that Codelco expects to produce only 1.344 million metric tons in 2026, barely 10,000 tons above its 2025 level, dashing hopes for a strong rebound.

Private Miners Also Under Pressure

The production slump extends beyond Codelco. Escondida, the world’s largest copper mine, saw a sharp decline in May, according to industry reporting. Other major operations, including Collahuasi, Anglo American Sur, and Quebrada Blanca, also faced production pressure.

For the first quarter of 2026, Chile’s total mine output fell 5.8% to 1.21 million tonnes, with the largest declines concentrated at El Teniente, El Abra, Spence, and Escondida. Cochilco data showed that January-May production was down 11.3% year-on-year, signaling that the weakness persisted well into the second quarter despite a modest recovery in June.

Global Supply Implications

Chile’s underperformance removes a critical source of expected growth from the global copper market. The country accounts for a little over one-fifth of global copper production and roughly 22% of global mine output, according to Cochilco-linked forecasts. A sustained Chilean shortfall can materially tighten both the refined metal and concentrate balances worldwide.

Cochilco’s 2026 outlook projects Chile will produce about 5.3 million tons, but the agency has warned that lower ore grades, maintenance requirements, operational constraints, and weak early-year performance will keep output subdued. The persistent gap between expected and actual production has become a defining feature of the market.

Price Response and Market Tightness

The supply constraints have already influenced price forecasts. Cochilco raised its 2026 copper price forecast to US$5.55 per pound, explicitly citing supply tightness and unstable concentrate availability as driving factors. The agency’s upward revision reflects the growing recognition that Chilean output is not recovering as quickly as previously anticipated.

Reuters and Bloomberg reporting on the weak Chilean quarter fits into a broader narrative of global supply tightness. Persistent Chilean shortfalls have been one of the key factors supporting copper prices, alongside broader constraints in global mine supply and concentrate markets. The country’s struggles continue to remove a cushion that markets had been counting on.

Outlook: A Structural Challenge

The second-quarter figures reinforce concerns that Chile’s copper output challenges are structural rather than temporary. Aging mines, declining ore grades, and the technical complexity of major projects have made it difficult for producers to maintain historical production levels, let alone grow them.

With Codelco’s 2026 guidance showing essentially flat output and private miners facing their own operational hurdles, the global copper market is likely to remain tightly supplied. Any unexpected demand recovery or further supply disruption could amplify the price effects of Chile’s prolonged production weakness.

Frequently Asked Questions

Why did Chile's copper output fall to its worst Q2 since 2007?

Chile’s second-quarter copper output dropped 7.7% year-on-year to 1.27 million metric tons due to declining ore grades, operational constraints, and maintenance issues at both state-owned Codelco and major private mines. Codelco’s El Teniente, Chuquicamata, and other divisions recorded double-digit declines in early 2026.

How does Chile's copper production affect global prices?

Chile accounts for roughly 22% of global mine output, so its production shortfall materially tightens world copper supply. Cochilco raised its 2026 copper price forecast to US$5.55 per pound, explicitly citing supply tightness and unstable concentrate availability linked to Chilean underperformance.

What is Codelco's production outlook for 2026?

Codelco expects to produce approximately 1.344 million metric tons of copper in 2026, only about 10,000 tons above its 2025 level, according to Reuters. The company faces ongoing challenges with falling ore grades and operational issues across its major mines, including El Teniente and Chuquicamata.
