Why lead is being left behind
Lead's underperformance relative to other base metals is a structural story. The automotive battery market — which consumes 80% of global lead — is mature, and substitution from lithium-ion starter batteries is slowly gaining traction. The International Lead and Zinc Study Group (ILZSG) estimates that lithium-ion substitution displaced 120,000 tonnes of lead demand in 2025, growing to 160,000 tonnes in 2026.
The market narrative has become self-fulfilling. Speculators are short, consumers are destocking, and the price has drifted lower. But the physical market tells a different story.
Secondary supply is the binding constraint
Approximately 60% of global lead supply comes from recycling (secondary), with the remainder from mining (primary). The secondary supply chain — scrap battery collection and recycling — is operating at full capacity globally. In North America, the Battery Council reports that recycling rates have reached 99%, leaving no room to increase secondary output without expanding collection infrastructure.
The constraint is becoming visible in China, where scrap battery prices have risen 12% year-on-year despite falling LME prices. Secondary smelters are paying a premium for feedstock, and margins are being squeezed. If LME lead falls further, marginal secondary smelters may cut output, reducing supply and stabilizing prices.
The primary supply side is not responding
Primary lead mine production is not growing because lead is mostly a by-product of zinc and silver mining. With zinc and silver prices elevated, lead mine output is increasing — but by-product lead is less responsive to price signals. The ILZSG projects a modest 2% increase in global lead mine output in 2026, insufficient to create a meaningful surplus.
The result is a market that looks balanced on paper but is tight in the secondary supply chain. The headline LME surplus of 50,000-80,000 tonnes masks a market where availability of specific grades and delivery points is constrained.
Bull, bear, and base cases
The bull case: secondary supply constraints intensify, scrap prices drive marginal smelter closures, and the headline surplus evaporates. LME lead rallies to $2,200/mt. This scenario requires a catalyst — such as a large smelter outage — that triggers short covering.
The bear case: lithium-ion substitution accelerates, Chinese lead demand falls 5%, and secondary supply remains steady. The surplus grows to 120,000 tonnes. LME lead tests $1,600/mt.
The base case: slow erosion of demand from lithium substitution, balanced by secondary supply constraints. LME lead trades $1,750-2,050/mt. The market is "productively uninteresting" — stable, predictable, and low volatility.
Lead procurement is about supply stability, not price speculation. The secondary supply chain is fully subscribed — do not assume you can increase requirements without paying a premium for scrap-derived lead. For battery manufacturers: build relationships with multiple secondary smelters and consider forward contracting at current levels near $1,850/mt. The downside is limited by recycling cost floors, and the upside spike risk from a smelter outage is underappreciated by the market. For industrial buyers: lead is one of the few commodities where annual fixed-price contracts with a single supplier are actually advisable, given the product's homogeneity and the stability of the secondary supply chain.
