Copper Prices Surge Amid Tariff Uncertainty, Triggering Market Volatility

Core Event: Record-High Prices Followed by a Sharp Reversal
Copper futures hit all-time highs earlier this week—$6.89 per pound on the New York exchange and about $14 800 per metric ton on the London Metal Exchange (LME). Within days, the same contracts slipped 3–5 %, with LME prices near $14 300 per ton and COMEX futures at $6.59 per pound. The reversal coincided with fresh reports that the U.S. administration has not yet finalized a proposed 15 % tariff on refined copper imports.
Background & Context
Demand for copper has been buoyed by electric-vehicle production, data-center construction for artificial-intelligence workloads, and broader grid-modernisation projects. Mine output fell 1.1 % in the first half of 2026, driven by poor weather and declining ore grades, with Chile’s production down 6.6 % according to the International Copper Study Group (ICSG).
President Donald Trump’s 2023 decree imposed a 50 % tariff on semi-finished copper products and left open a staged tariff on refined copper—15 % to begin later this year, rising to 30 % the following year. The prospect of that higher duty has spurred “stockpiling” of metal for fear of future scarcity.
Data & Statistics
- Record-high LME price: ~ $14 800/ton; current price: $14 300/ton (? 3 % drop).
- COMEX price fell from $6.89 to $6.59 per pound (? 4 % decline).
- Copper futures are up > 15 % year-to-date, outpacing gold, silver, bitcoin and the S&P 500.
- Global copper mine production down 1.1 % in H1 2026; Chile’s output down 6.6 % (ICSG).
- U.S. copper inventories in COMEX warehouses have risen for 57 consecutive days, reaching a record 767 495 short tons.
- Freeport-McMoRan shares fell 8 % to $70.43; Southern Copper down 7 % to $195.66; Teck Resources down 7 % to $65.08.
- The Global X Copper Miners ETF (COPX) dropped 7 % as its three largest U.S. constituents repriced in unison.
Official Statements & Responses
Michael Cuoco of StoneX Financial observed fresh buying from speculative funds and Chinese manufacturers after the initial sell-off, indicating that market participants are still seeking exposure despite policy doubts.
On-the-Ground Reports
Mining stocks reacted sharply: Freeport-McMoRan, the largest U.S. copper producer, dropped 7.2 % after the tariff-uncertainty report; other majors such as Southern Copper, Teck Resources, Hudbay Minerals and Rio Tinto posted declines of 4–8 %. The sector-wide sell-off erased billions of dollars in gains accumulated over the summer.
Conflicting Reports & Gaps
Price coverage varies between exchanges: LME contracts traded near $14 200/ton, while COMEX prices were $6.49 per pound (? $14 308/ton). The spread between cash and three-month forward contracts narrowed from $41 to $5 per ton, but the exact timing of any tariff implementation remains unspecified. No definitive government timetable has been disclosed, leaving market participants to speculate on policy timing.
What’s Next
The administration is expected to issue a final decision on refined-copper tariffs before the start of 2027. Analysts will watch the LME afternoon fix for signs of price stabilization; a concrete tariff announcement could either cement the scarcity premium or remove it, reshaping inventory flows and mining-sector valuations.
