Global copper mine output fell 1.1% in H1 2026, and Morgan Stanley now expects the first full-year mine-supply decline since 2017, led by Chile's weakest quarter in 19 years.
At a glance
- Global copper mine production fell 1.1% in the first half of 2026, and Morgan Stanley now projects flat-to-lower full-year output -- the first annual decline in global mine supply since 2017
- Chile, source of just under a quarter of the world's mined copper, posted its weakest second quarter in at least 19 years and has cut its full-year guidance twice this year, now pointing to a 2.6% annual decline
- Output also fell in Indonesia and the Democratic Republic of Congo, while Chile's state miner Codelco and Freeport-McMoRan both posted double-digit production declines at their operations
- Copper exploration economics have deteriorated sharply: the industry found 714.8 million tons of copper in the 1990s alone, versus only 687 million tons across the 26 years since 2000
What happened
Global copper mine production fell 1.1% in the first half of 2026, according to the International Copper Study Group (ICSG), and Morgan Stanley now expects full-year output to come in flat to slightly lower -- what would be the first annual decline in global copper mine supply since 2017. Chile, which supplies just under a quarter of the world's mined copper, posted its weakest second quarter in at least 19 years and has cut its full-year production guidance for a second consecutive quarter, now pointing to a 2.6% annual decline. Output also fell in Indonesia and the Democratic Republic of Congo over the same period, while Chile's state miner Codelco and Freeport-McMoRan, the largest US-listed copper producer, both reported double-digit production declines at their own operations. Three-month copper on the London Metal Exchange (LME) touched a fresh record of $14,779 a tonne this week, up roughly 24% year-to-date and 51% over the past 12 months, with COMEX futures trading near $3.74 a pound. Frank Holmes, chief executive and chief investment officer of US Global Investors (NASDAQ: GROW), argues in his Frank Talk column that this supply-side deterioration -- not tariff speculation -- may be the more durable force behind copper's advance.
The details
The headline number sounds modest: global copper mine output fell 1.1% in the first half of 2026. What makes it significant is the context Morgan Stanley attaches to it. The bank started the year expecting global mine supply to expand and has since revised that view to production running flat or slightly lower for the full year -- which, if it holds, would be the first annual decline in global copper mine supply since 2017.
Much of that decline traces back to one country. Chile supplies just under a quarter of the world's mined copper, and its second quarter was the weakest in at least 19 years. The state has cut its own full-year guidance for a second consecutive quarter, arriving at an expected 2.6% annual decline. Indonesia and the Democratic Republic of Congo, two of the other largest copper-producing nations, posted lower output over the same period, while Codelco, Chile's state miner, and Freeport-McMoRan, the largest US-listed copper producer, both reported double-digit production declines at their own operations. When the world's top producer, its state miner, and the largest US-listed copper company all report shrinking output in the same window, that is a broad-based supply problem, not one mine's bad quarter.
The deeper issue sits upstream of any single mine's results: exploration has become dramatically less productive. Companies found 714.8 million tons of copper in the 1990s alone. Across the 26 years since 2000, they have found only 687 million tons combined -- less total discovery spread over nearly three decades than in one. The cost of finding that copper has climbed just as sharply: roughly $8 a ton in the 1990s versus close to $1,889 a ton in exploration spending since 2020, a roughly 225-fold increase. Rigs are also drilling deeper to find what remains -- average drilling depth is up nearly 50% since 2010, to around 600 meters -- which adds cost and years to every discovery before a mine is even permitted. From discovery to first production now averages 17.5 years, meaning today's thin exploration results will not show up as new mined tonnage until well into the next decade.
That timeline mismatch is what separates this from an ordinary supply hiccup. Copper demand is not waiting for exploration to catch up: S&P Global projects global copper demand climbing from about 28 million tons in 2025 to 42 million tons by 2040, a roughly 50% rise, as grid buildouts, electrification and data-center construction keep pulling on the metal. A market that just produced less copper than it did a year earlier, running into a demand curve that keeps climbing, is a structurally different setup than the US tariff-driven stockpiling that has dominated copper headlines in recent weeks -- that story is about where existing metal sits, not about how much of it the world can actually mine.
None of this locks in where prices go from here. A single mid-year bank revision is not a certainty, Chile's second half could stabilize, and sustained high prices could eventually pull fresh capital into exploration or speed up permitting faster than the 17.5-year average suggests. But the ICSG's 1.1% figure and Morgan Stanley's revised call describe a supply condition that would persist regardless of how any single country's tariff policy resolves -- a distinction that matters for separating a temporary price spike from a longer shift in how much copper the world can actually produce.
Why it matters
Indian wire, cable and EV-component manufacturers who buy copper priced off the LME and COMEX benchmarks are exposed to a cost base that may not simply normalize once the US tariff question is resolved. If Morgan Stanley's revised call holds, part of copper's current price strength reflects an actual, multi-country contraction in mined supply -- a slower-moving problem than a stockpiling trade, and one that a single policy decision in Washington cannot undo.
Our read
Outlook: bullish. Global mine production fell 1.1% in the first half of 2026, and Morgan Stanley now projects the first annual decline in copper mine supply since 2017, with Chile's guidance cuts and double-digit declines at Codelco and Freeport-McMoRan pointing to a broad-based supply contraction rather than a single country's shortfall -- a structural tightening alongside record LME and COMEX prices, tempered by the possibility that Morgan Stanley's 'flat to slightly lower' framing describes only a shallow decline, and that higher prices could eventually draw fresh exploration investment.
What to watch
- ICSG's full-year 2026 global mine production data, to see whether the 1.1% first-half decline holds or deepens
- Chile's subsequent quarterly guidance updates, given two consecutive downward revisions already this year
- Codelco and Freeport-McMoRan production reports for signs of stabilization or further double-digit declines
- New exploration and permitting announcements that could signal a faster supply response than the historical 17.5-year average

Supply Drivers
Morgan Stanley began 2026 expecting global copper mine supply to expand but now projects full-year output running flat to slightly lower -- which would be the first annual decline in global mine supply since 2017. Underlying that shift, exploration economics have deteriorated sharply: explorers found 714.8 million tons of copper in the 1990s alone but only 687 million tons combined across the 26 years since 2000, the cost of finding a ton of copper has risen roughly 225-fold (from about $8 in the 1990s to about $1,889 since 2020), and it now averages 17.5 years to carry a discovery through to production.
Mining Production
Chile, which supplies just under a quarter of the world's mined copper, posted its weakest second quarter in at least 19 years and has cut its full-year production guidance for a second consecutive quarter, now pointing to a 2.6% annual decline. Output also fell in Indonesia and the Democratic Republic of Congo over the same period, while Chile's state miner Codelco and Freeport-McMoRan both reported double-digit production declines at their own operations.
Global Consumption
S&P Global projects global copper demand rising from about 28 million tons in 2025 to 42 million tons by 2040, a roughly 50% increase driven by grid buildouts, electrification and data-center construction -- a demand trajectory that keeps climbing even as mine supply contracts for the first time in years.
What could lift prices
- Global copper mine production fell 1.1% in the first half of 2026, and Morgan Stanley now expects the first full-year mine-supply decline since 2017
- Chile has cut its production guidance twice this year to a 2.6% annual decline after its weakest quarter in 19 years, while Codelco and Freeport-McMoRan both posted double-digit output declines
- Exploration economics have deteriorated sharply -- discovery costs are up roughly 225-fold since the 1990s, and it now takes an average of 17.5 years to bring a discovery to production, limiting how quickly new supply can respond even at higher prices
- S&P Global projects global copper demand climbing about 50% by 2040, adding a rising demand curve on top of a contracting supply base
What could weigh on prices
- Morgan Stanley's own framing describes production running "flat to slightly lower," a shallow decline rather than a sharp contraction, and sustained high prices could eventually pull fresh capital into exploration or speed up permitting
Country impact
| Country | Impact | Reason |
|---|---|---|
| Chile | High | As the source of just under a quarter of the world's mined copper, Chile's own guidance cuts are the single largest driver of the projected global mine-supply decline. |
| United States | Medium | Freeport-McMoRan, the largest US-listed copper producer, reported a double-digit production decline at its own operations, and Morgan Stanley's revised supply outlook shapes how US investors and manufacturers price in copper availability. |
| Indonesia | Medium | One of the countries where mined copper output declined in the first half of 2026, contributing to the global 1.1% production drop. |
| Democratic Republic of Congo | Medium | Another major copper-producing nation reporting lower output in the first half of 2026, adding to the broad-based nature of the global decline. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Mining | Positive | Producers with stable output stand to benefit from record prices even as several of the industry's largest names -- Chile's state sector, Codelco and Freeport-McMoRan among them -- report their own production declining, while the roughly 225-fold rise in exploration cost per ton since the 1990s raises the bar for any new project to reach production. |
Who gains, who loses
- Copper miners with producing assets not facing their own output declines: A contracting global supply base against record prices favors producers able to maintain or grow output while peers including Chile's state sector, Codelco and Freeport-McMoRan report declines.
- Copper-consuming manufacturers, including Indian wire, cable and EV-component makers: A supply base that is contracting rather than merely relocating, as in the tariff-driven stockpiling story, raises the risk that elevated input costs persist independent of any single country's trade policy.
Other ways this could play out
- If Chile's output stabilizes in the second half of 2026 and no further country-level declines emerge, global mine supply could land flat rather than negative for the year, softening Morgan Stanley's downside case
- If elevated copper prices persist long enough to justify investment in deeper, costlier deposits, exploration output could eventually recover, though the 17.5-year average discovery-to-production timeline limits how quickly that would show up as mined supply
Price risks
- A deeper-than-expected decline in Chilean output, or further downgrades from Codelco or Freeport-McMoRan, could tighten supply further and add to upward price pressure
- A second-half rebound in Chilean production or faster-than-average project approvals could ease the supply narrative and reduce the premium currently building around mine-supply scarcity
Historical comparison
- 2017: The last time global copper mine supply posted a full annual decline, according to Morgan Stanley -- a gap of roughly nine years before the currently projected 2026 downturn.
- 1990s vs. since 2020: Copper exploration found 714.8 million tons in the 1990s alone at roughly $8 a ton; discoveries since 2020 have cost close to $1,889 a ton, a roughly 225-fold increase in the cost of finding new copper.
