Why copper prices move.

Electrification underpins the price

The deepest driver of copper prices is demand that is structural rather than cyclical. Grid expansion and reinforcement — which Wood Mackenzie's copper research head calls the single most important demand driver over the coming decades — is embedded in regulation and industrial policy across the US, Europe, China, and India. Unlike the old cycle, when Chinese construction swung copper demand up and down, today's demand growth comes from electrification commitments that governments have already made: EV adoption curves, renewable buildouts, and data-center construction. BMI forecasts EV copper demand of 2.2 million tons in 2030 versus 1.2 million in 2025; CRU sees data-center demand exceeding 650,000 tons by 2030. This policy-embedded demand does not guarantee high prices — supply can always catch up, and recessions still bite — but it sets a firm floor under the long-term thesis that has carried copper to records. When sellers ask why copper is "expensive now," the honest answer starts here: the world committed to using much more of it, all at once.

Mine disruptions and declining grades

Above that structural floor, supply shocks do the moving. Copper mining is a concentrated, politically exposed business, and disruptions are routine: in the first half of 2026, global mine output fell 1.1% and concentrate output 2.6%, with sharp declines in Chile, Indonesia, and the DRC, while the Cobre Panama closure continued to tighten concentrate markets. Underneath the headlines runs a slower squeeze: ore grades have declined more than 25% over two decades. Chilean grades average 0.6 to 0.7%, the giant Escondida mine sits below 1% and may fall toward 0.5%, and each tenth of a percent means more rock, more energy, and more cost per ton of copper. Permitting delays and rising energy costs restrain new supply from responding quickly. The result is a market where physical tightness lives in ore and concentrate — the 2025–2026 negative treatment charges are the proof — even when refined metal looks statistically comfortable. For scrap sellers, mine tightness is quietly bullish: when primary supply struggles, secondary supply — scrap — becomes structurally more important, and roughly a third of global copper supply already comes from recycling.

Tariffs, inventories, currency, speculation

The defining market event of 2025–2026 has been US trade policy. The Section 232 copper investigation — ordered February 25, 2025, covering all forms from mined ore to derivatives — led to Proclamation 10962 (July 30, 2025): 50% tariffs on semi-finished copper products (pipe, wire, rod, sheet, tube) and copper-intensive derivatives, effective August 1, 2025, covering $15.5 billion of 2024 imports. Refined cathode was exempted — a decision that imploded the $1-per-pound COMEX premium overnight — but a phased refined-copper tariff (15% from January 2027, 30% from 2028) plus a 25% domestic-sales requirement for high-quality scrap remain on the table, with the Commerce Department's June 30, 2026 update deadline passing with no White House decision announced as of early September 2026. Tariff anticipation has distorted physical flows: July 2026 US refined imports hit a record 225,094 tons (highest since 1990 records began), COMEX inventories hit a record 764,597 short tons after 53 straight days of increases, and LME stocks rose 61%. CRU estimates the tariff threat turned a projected 639,000-ton 2026 global surplus into at best a balanced market. Around these fundamentals orbit the usual amplifiers: a stronger US dollar weighs on commodities, and traders repeatedly position around tariff expectations — the July 2025 premium spike and implosion, the 2026 re-widening of the CME-LME arbitrage — showing how policy speculation amplifies physical tightness. Ironcrest does not publish price forecasts or per-pound prices; the point of understanding these drivers is timing and context for your selling decision, not prediction.
