Supply Constraints: Structural, Not Cyclical
The copper market faces a structural supply bottleneck. ICSG projects refined output growth at just 0.9% in 2026, constrained by declining ore grades, chronic underinvestment in new mines, and a severe shortage of concentrate feed. Treatment and refining charges (TC/RCs) have fallen to historic lows, confirming the squeeze at the smelter level is real and deepening.
Major mine disruptions have compounded the deficit. Grasberg's transitional output, Kamoa-Kakula ramp delays, and operational issues across Chilean assets have removed significant tonnage. JPMorgan projects a 330kt deficit for 2026; ING is even more bearish at 600kt. Goldman Sachs sits at the other extreme with a 160kt surplus, but the consensus has clearly moved toward scarcity.
[FACT] ICSG projects refined output growth at 0.9% in 2026. [ESTIMATE] The true deficit likely falls between 150kt and 330kt, depending on Chinese import demand in H2.
Demand: Electrification, AI, and the China Question
Demand growth is driven by three structural forces: the energy transition (grid modernization, EVs), AI data-center buildout, and China’s decarbonization push. JPMorgan estimates AI data centers alone could consume ~475,000 tonnes of copper in 2026. Combined with grid investments and EV charging infrastructure, these sectors represent multi-year demand acceleration.
China remains the swing factor, accounting for 58% of global refined consumption. ICSG projects Chinese apparent use rising 0.8–2.0% in 2026, with solar and EV sectors offsetting persistent real estate weakness. The risk is asymmetric: stronger Chinese stimulus could push copper above $14,000/t; a deeper property downturn could test the downside below $9,500/t.
[FACT] Global refined usage projected at 28.7Mt in 2026, up 2.1% YoY (ICSG). [ESTIMATE] AI data-center copper demand could add 300–500kt of incremental consumption annually through 2030.
Price Scenarios: Bull, Base, Bear
Base Case ($10,000–12,000/t): The market oscillates between small surplus and deficit as Chinese demand stabilizes and mine restarts partially compensate. LME trades in a $2,000/t range with a tightening bias into year-end. Probability: ~50%.
Bull Case ($12,000–14,000/t): A supply shock (Grasberg delays, Chilean disruption, or Section 232 tariffs) coincides with Chinese stimulus-driven restocking. LME prices re-test all-time highs. Probability: ~25%.
Bear Case ($9,000–10,500/t): Chinese property defaults accelerate, copper-intensive manufacturing contracts, and mine supply returns faster than expected. The deficit narrative breaks. Probability: ~25%.
The Section 232 Wildcard
The US is expected to decide by late June whether to impose Section 232 tariffs on copper. Comex stocks have surged 550% since the probe was ordered, reflecting pre-tariff stockpiling. A 15% tariff on copper imports would distort global trade flows, widen COMEX-LME spreads, and segment the market into US and ex-US price zones.
Decision Matrix
| Action | Role | Timeline |
|---|---|---|
| Lock H2 supply contracts before Section 232 ruling | Procurement | Before late June 2026 |
| Evaluate LME hedging vs fixed-price terms | Treasury | Q3 2026 |
| Diversify concentrate sources away from Chile/Peru | Supply Chain | Q3–Q4 2026 |
| Model $2,000/t copper price swing in contingency budget | CFO | June 2026 |
| Increase scrap-copper procurement as substitute | Procurement | Immediate |
| Monitor Chinese property stimulus announcements | Market Intel | Weekly |
The window for locking in H2 supply at current levels is narrowing. The Section 232 decision, combined with structural deficit dynamics, creates asymmetric upside risk. Buyers should extend contract coverage through Q4 2026 before the ruling and prepare for a potential $2,000/t price swing. Scrap procurement and alternative sourcing should be prioritized.
