Goldman cuts copper forecast on soft demand, warns of potential price declines

Goldman Sachs cut its 2026 copper price forecast to $12,650/tonne from $12,850 and now expects a 2024 global refined copper surplus of 490,000 tonnes (up from 380,000t), trimming demand growth to 1.6% from 2%. The bank projects a 0.4 percentage-point drag to global GDP from Middle East energy shocks, sees Q2 2026 averaging $12,700/t before drifting to a $12,000 fair value in H2, but retains a long-run $15,000/2035 target. Analysts warn current prices are well above their 2026 fair value (~$11,100) and vulnerable if the economic outlook deteriorates, while noting supply risks if Strait of Hormuz disruptions to sulfur shipments to the DRC are prolonged.

Analysis

Near-term copper price dynamics will be dominated by two non-linear supply channels that markets are underpricing: logistics/insurance risk through maritime chokepoints and the fragility of smelter/refinery feedstock chains. A short disruption in seaborne inputs can paper-over itself via inventory drawdowns, but a >2–3 month interruption has outsized probability of forcing temporary smelter curtailments in higher-cost refining hubs, producing sharp spot spikes and backwardation rather than a gradual tightening.

Structurally, electrification creates durable demand growth but delivery is lumpy because new mine supply has long lead times and capital discipline keeps marginal expansion slow. That disconnect amplifies calendar spread moves — near-dated contracts react violently to geopolitical shocks while longer-dated contracts reflect the multi-year build-out of copper-intensive grid and EV infrastructure, creating repeatable carry/arbitrage opportunities.

Key catalysts and time horizons to watch are distinct: days–weeks for shipping incidents, insurance rate jumps, and headline geopolitics that can flush risk-premia; months for Chinese industrial demand shifts and rolling maintenance/refinery throughput changes; 12–36 months for new mine ramps and permitting timelines that ultimately control structural balances. Reversals come from rapid diplomatic de-escalation or an aggressive macro slowdown that collapses industrial metals demand, both of which would liquidate the current risk premium quickly.

Positioning should marry asymmetric option structures with directional exposure to low-cost, balance-sheet-strong producers and selected calendar spreads. Hedging is essential: this is a market where headline risk drives outsized intraday moves but the multi-year structural story remains intact, so size for volatility, not just direction.

Key Decisions for Investors

• Overweight low-cost producers: initiate a 6–18 month tactical overweight in FCX and SCCO (equal-weight) sized to 2–3% of portfolio each. Rationale: high operating leverage to copper plus balance-sheet optionality; risk: 15–20% drawdown if macro demand collapses; reward: 30–60% upside if supply disruption/backwardation reasserts over next 12 months. Use staggered entries on 5–10% price retracements.
• Buy COPX (copper miners ETF) with downside protection: purchase COPX and finance a 3–6 month out-of-the-money put (collar) to limit 20% downside while retaining most upside into a supply shock. Timeframe: 3–9 months to capture volatility rerating. Cost: small premium paid or sold call to fund puts; trade-off: capped high-end but protected tail risk.
• Copper calendar spread (futures): buy 1–3 month prompt COMEX/LME copper and sell the 9–12 month contract sized 1:1 to capture near-term supply shock premium. Timeframe: 0–6 months. Risk: contango steepening if macro weakens — cap exposure to 2% of portfolio and exit on 3–5% realized move against position.
• Relative-value pair: long COPX / short XLI (materials exposure vs broad industrials) for 3–6 months to exploit divergence where energy/geopolitics lift metals but compress industrial margins. Position size small (1–2% net) with stop-loss if broader equity risk premium spikes; expected asymmetric payoff if commodity-specific shock occurs while broader industrial activity holds.
