Copper — Deep Resource Analysis¶

Disruption Scale¶

Pre-existing structural deficit now compounded by war. The global copper market entered 2026 already running a ~330,000 tonne refined deficit (J.P. Morgan estimate). The war has added three simultaneous pressure vectors: Iran's ~400,000 tonnes/year mine output at risk, sulphur disruption spiking smelting costs worldwide, and energy price inflation hitting every mine and smelter on earth. Copper is the single most important metal for electrification — and the war is making the energy transition more urgent while simultaneously making it harder to execute.

Iran's Copper Complex — What's At Risk¶

Iran operates three major copper mining complexes, all run by the National Iranian Copper Industry Company (NICICO):

Mine	Province	Concentrate Output (2022)	Reserves	Status (Day 24)
Sarcheshmeh	Kerman	729,000 t concentrate	826M t proven; 1.2B t estimated	World's 2nd-largest copper deposit. ~550 km from nearest strike zones. Operational but exports frozen
Sungun	East Azerbaijan	334,000 t concentrate	470M t proven; 1B t potential	Northern Iran; closer to conflict zones
Miduk	Kerman	153,000 t concentrate	170M t proven	Adjacent to Sarcheshmeh complex

Combined reserves: 3.4 billion tonnes of ore across three sites.

Iran's production trajectory: Output rose from 315,000 metal tonnes (2017) to ~410,000 metal tonnes (2025). The government's Seventh Development Plan targeted 700,000 t/yr cathode capacity — now indefinitely frozen.

War Impact on Iranian Copper¶

Mines physically intact (as of Day 24): Located in Kerman and East Azerbaijan provinces, distant from primary strike zones around Tehran, Isfahan, and military installations
Export routes severed: Hormuz blockade prevents seaborne copper concentrate shipments; overland routes to Turkey/Pakistan theoretically open but logistically degraded
China connection minimal: China imports only tens of thousands of physical tonnes of Iranian copper concentrate annually (~0.1% of China's total imports) — SMM analysis confirms limited direct supply chain impact
Net loss to global market: ~350,000-400,000 t/yr of mine output functionally offline due to export disruption, even if mines continue operating

The Smelting Crisis: Sulphur → Copper Cascade¶

This is where the war's real copper impact lies — not in Iran's mines, but in the chemistry of copper processing.

How Copper Smelting Works¶

80% of copper production uses pyrometallurgical processing (smelting sulphide ores)
Smelting generates 3-4 tonnes of sulphuric acid per tonne of copper produced (byproduct)
Sulphuric acid is also a critical input for hydrometallurgical copper extraction (SX-EW process, ~20% of production)
Sulphur/sulphuric acid represents 20-25% of copper smelting costs

The Disruption Chain¶

Gulf sulphur disrupted (44% of global production, 50% seaborne trade)
  ├──→ Sulphuric acid prices spike globally
  │     ├──→ Hydrometallurgical copper production costs surge (SX-EW plants)
  │     ├──→ Fertilizer production falls (phosphates need sulphuric acid)
  │     └──→ Indonesia loses 75% of sulphur imports → nickel smelting hit
  ├──→ Chinese smelters squeezed (40% of China's sulphur is imported)
  │     └──→ Already operating at zero TC/RCs — now cost-negative
  └──→ Global refined copper output constrained regardless of mine output

China's Smelter Dominance — Already in Crisis Pre-War¶

China operates ~50% of global copper smelter capacity
China produced 47.4% of global refined copper (27.5 Mt total, 2025)
Treatment charges (TC/RCs) collapsed to $0/tonne for 2026 — unprecedented (Antofagasta-China benchmark)
China's top smelters already cutting output >10% before the war due to unprofitable processing fees
40% of China's sulphur is imported — Middle East disruption transmits directly into Chinese smelting economics
CSPT (China Smelters Purchase Team) refused to set Q1 2026 TC/RC guidance — fourth consecutive quarter of non-guidance

The war didn't create the smelter crisis. It poured gasoline on it.

Price Trajectory¶

Period	LME Copper ($/tonne)	COMEX ($/lb)	Context
Late Nov 2025	~$11,000	~$5.00	Pre-rally
Dec 2025	$12,000+	~$5.45	Record broken; +40% annual gain (largest since 2009)
Jan 29, 2026	$14,527.50	~$6.60	All-time high (intraday); China speculation + AI/data center demand
Early Feb 2026	~$13,000	~$5.90	Goldman target; tariff front-running
Feb 28, 2026	~$12,800	~$5.80	War begins
Mid-March 2026	~$11,750	~$5.44	-8% crash; panic selling on LME; copper wipes out 2026 gains
March 20, 2026	$11,750	$5.44	-5.25% YTD; war demand destruction fears dominate

Price paradox: The war should be bullish for copper (supply disruption, Iran offline, sulphur squeeze) but the demand destruction from a potential global recession is currently winning. Markets are pricing in the demand hit faster than the supply hit — for now.

Forecasts: - J.P. Morgan: $12,500/mt Q2 2026, ~$12,075/mt full-year average - Goldman Sachs: decline to $11,000/mt by year-end - StoneX: $11,490/mt average for 2026

Demand by Sector¶

Current Consumption (~28 Mt refined copper, 2025)¶

Sector	Share	Key Applications
Building & construction	~28%	Wiring, plumbing, HVAC, roofing
Electrical equipment	~26%	Power cables, transformers, grid infrastructure
Electronics	~13%	PCBs, connectors, semiconductors packaging
Transportation	~12%	Vehicle wiring, EV motors/batteries, rail
Industrial machinery	~11%	Motors, heat exchangers
Consumer products	~10%	Appliances, coins, cookware

Energy Transition Copper Intensity¶

Technology	Copper Required	vs. Conventional
Electric vehicle	53-83 kg per vehicle	2.4-4x more than ICE vehicle (~22 kg)
EV charger (standard)	0.7 kg each	New demand category
EV charger (fast DC)	up to 8 kg each	New demand category
Onshore wind turbine	~4.7 tonnes per turbine	2.5x more than gas plant per MW
Offshore wind turbine	~8-10 tonnes per turbine	5x+ more than gas plant per MW
Solar farm	~5.5 tonnes per MW	4x more than gas plant per MW
Data center	20-40 tonnes per MW capacity	Growing exponentially with AI

Key projections: - EV copper demand alone: >2.5 Mt by 2030 - Data center copper demand: ~475 kt in 2026 (+110 kt YoY) - Total copper demand by 2040: projected 42 Mt (vs ~28 Mt today — 50% increase) - S&P Global (Jan 2026): copper supply shortfall is a "systemic risk" to the economy

The Green Transition Paradox¶

The war simultaneously: 1. Increases urgency for energy independence → accelerates renewable/EV investment 2. Disrupts the supply chain needed to build renewables → sulphur, energy costs, shipping 3. Destroys demand through recession fears → copper prices fall despite supply tightening

This creates a coiled spring: when the war ends, pent-up green transition demand will hit a supply chain that has been degraded during the conflict. The post-war copper price spike could exceed the wartime one.

Defense Applications¶

Copper is embedded throughout the weapons systems currently being consumed in this war:

Application	Copper Use	Relevance
155mm artillery shells	~0.5 kg copper per shell	Rotating band, driving band, fuze components
Ammunition casings	Brass (70% copper alloy)	Small arms through naval guns
Guided missiles (Tomahawk, etc.)	Wiring, motor windings, connectors	Precision guidance systems use beryllium copper
Patriot missile system	SmCo magnets + copper wiring	Guidance, control, radar
Naval vessels	Copper-nickel alloys	Corrosion resistance, heat exchangers
Military PCBs	Copper traces on all boards	Every smart weapon, drone, radar, comm system
F-35 wiring harness	>60 km of copper wire per aircraft	Flight systems, weapons, avionics

The US has expended 5,197+ precision munitions in the first 96 hours alone. Each munition consumes copper that must be replaced from a market already in deficit. The Pentagon identified copper as a critical mineral for national defense — the war is simultaneously consuming and constraining it.

Supply-Demand Balance (2026 Projections)¶

Category	Volume (kt)	Notes
Global mine production	~23,400	Pre-war trajectory; actual now lower
Iran offline	-350 to -400	Export disruption even if mines run
Indonesia Grasberg cut	-200 (approx)	Pre-war mudslide; 35% output reduction
Smelter capacity cuts (China)	-300 to -500 (refined)	>10% output cut; zero TC/RCs; sulphur squeeze
Demand (pre-war forecast)	~28,000 (refined)	Includes EV, grid, AI data center growth
Demand destruction (war)	-500 to -1,000	Recession fears, construction slowdown
Net refined deficit	~330-600 kt	Range: J.P. Morgan (330 kt) to ING (600 kt)

Goldman Sachs is the outlier, projecting a 160 kt surplus — they're betting on deeper demand destruction.

Cascade Effects Summary¶

Immediate (Days 1-30) — Current phase¶

Iran copper exports frozen (Hormuz blockade)
Copper prices crash 8% on demand destruction fears (counterintuitive)
Chinese smelters face sulphur supply tightening
TC/RCs already at zero; further squeeze unsustainable

Medium-Term (Months 2-6)¶

Sulphur shortage fully transmits to copper smelting costs
Chinese smelter cuts deepen beyond 10%
Refined copper availability tightens globally
EV and renewable manufacturers face input cost escalation
Defense restocking competes with civilian demand

Long-Term (6-18 months post-war)¶

Coiled spring effect: pent-up green transition demand meets degraded supply chain
Post-war copper price spike likely exceeds wartime levels
Iran reconstruction requires copper (self-consuming its own supply)
Energy transition timeline pushed back 12-24 months
China's smelter dominance becomes geopolitical leverage point

Strategic Implications¶

Copper is the energy transition's bottleneck — S&P Global called it a "systemic risk" in January 2026. The war validates this assessment in real time.
The sulphur-copper link is underappreciated — Most analysis focuses on mine output. The real constraint is smelting economics. A mine can produce all the concentrate in the world; if smelters can't process it profitably, refined copper doesn't reach markets.
China controls the refining chokepoint — 50% of smelter capacity, 47% of refined output. China's decisions on smelter output, sulphur purchasing, and strategic stockpiling will determine global copper availability more than any mine.
Defense vs. green transition competition — Both need copper. Both are being prioritized by Western governments. There isn't enough copper for both at current production levels. The war forces a prioritization that governments don't want to make explicit.
Post-war is worse than wartime for copper — The demand destruction masking the supply problem will reverse. When it does, the structural deficit reasserts with a degraded supply chain behind it.
