Copper Nears Record High Amid US Supply Drain and Aurubis Warning
London — Copper prices advanced toward record levels on Wednesday as Aurubis AG, Europe’s largest smelter, warned that massive shipments diverted to North America are draining global inventories. The red metal edged up 0.2% to $14,612 per metric ton in London, remaining within striking distance of its all-time high set last month.
The rally reflects growing anxiety over physical market availability. Benchmark Minerals reported that Hamburg-based Aurubis offered a record premium of $347 per ton for 2027 delivery—a 10% increase over current contract levels. Regional premiums, which buyers pay above cash pricing on the London Metal Exchange (LME), serve as a closely watched barometer of physical market tightness.
Key Takeaways
- Supply Squeeze: Traders are shipping record volumes of copper to the US to front-run prospective tariff policies, leaving European warehouses significantly depleted.
- Record Premiums: Aurubis proposed a record $347/ton surcharge for 2027 supplies, signaling persistent structural deficits.
- Labor Relief: Gains were capped after union leaders signaled an agreement to avoid a disruptive strike at Chile’s Escondida mine, the world's largest copper operation.
Front-Running US Tariffs Drains European Inventories
The surge in US-bound shipments comes as market participants rush to establish physical positions ahead of anticipated trade tariffs on imported industrial metals.
"There is a degree of tightness in the market, and significant volumes of metal have been redirected to the United States, leaving warehouses virtually empty," an Aurubis spokesperson stated, while declining to comment on specific contractual premiums.
LME three-month copper rose as much as 0.8% earlier in the session to reach $14,695 per ton—its highest intraday level since September 23. Prices spiked near $14,900 per ton last month before consolidating amid broader economic uncertainty and geopolitical friction in the Middle East.

Chilean Mine Stoppages and Fed Rate Uncertainty
Momentum softened slightly after union leadership at BHP Group’s Escondida mine in Chile indicated that a deal to avert a strike was virtually finalized. Any operational halt at Escondida would have exacerbated an already fragile supply line in South America. Chile previously recorded its weakest monthly output in over 15 years during August, hit hard by worker disputes and adverse weather conditions.
Concurrently, commodity traders are keeping a close eye on macroeconomic signals out of Washington. Federal Reserve Bank of New York President John Williams indicated that an additional interest rate increase remains appropriate before year-end to rein in inflation, though he signaled no further hikes would be required in 2027.
Elevated benchmark interest rates typically impose headwinds on industrial metals by increasing carrying costs and dampening manufacturing activity.
Structural Squeeze or Temporary Bottleneck?
The physical copper market is facing a double pressure point: long-term demand driven by energy transition infrastructure and immediate logistical distortions caused by tariff speculation. While a strike avoidance at Escondida offers short-term relief, record producer premiums in Europe suggest that physical availability will remain constrained well into 2027.
FAQ
- Why are copper prices surging toward record highs in 2026? Prices are driven by heavy physical shipments to the US ahead of expected tariffs, tight European warehouse inventories, and long-term supply constraints out of South America.
- What is the significance of Aurubis raising its premium to $347 per ton? The surcharge paid above LME cash prices reflects severe physical scarcity. A 10% year-over-year increase indicates that industrial buyers expect supply tightness to persist through 2027.
- How does US monetary policy affect copper valuation? Higher interest rates increase holding costs for physical metal inventories and slow down industrial activity, which can temporarily weigh on futures prices even amid tight supply fundamentals.
