Zinc is defying the demand-side gravity that has weighed on most industrial metals this year. LME three-month zinc is trading in the $3,400–3,500/t range in late May — perched near multi-year highs — while global construction activity contracts and manufacturing PMIs in both Europe and China signal persistent weakness. The rally has surprised consensus forecasts and forced a reassessment of how the zinc market actually clears. (FACT: Reuters, May 2026)
The answer lies on the supply side. LME inventories, which collapsed below 50,000 tonnes in October 2025, have rebuilt to roughly 138,000 tonnes — but a full 11% of that registered stock is tied up as cancelled warrants, meaning the metal is already earmarked for physical delivery and effectively unavailable to the spot market. The real freely available inventory is far thinner than headline numbers suggest, creating a structural bid under the cash-to-three spread. (FACT: Fastmarkets, S&P Global, May 2026)
The premium for prompt physical delivery tells the same story. In the US Midwest and European markets, physical premiums for zinc have widened as buyers compete for limited on-warrant tonnage. This is not a demand-driven recovery — it is a supply squeeze masquerading as one. The zinc concentrate market remains tight, with treatment charges (TCs) for concentrate dropping sharply and signalling limited raw material availability for smelters. When smelter feed is scarce, refined metal output naturally contracts regardless of what end-users are doing. (FACT: Fastmarkets, May 2026)
The April 2026 average LME cash settlement of $3,355/t, up 5.4% from March, captures the trajectory well. Each subsequent month has seen the floor ratchet higher as the market reprices the risk of sustained tightness. Downstream consumers — galvanizers, construction suppliers, automotive component manufacturers — are absorbing higher costs not because they can pass them through to their own customers, but because supply availability is the binding constraint, not price. (FACT: Nasdaq, 2026)
Yet the rally has limits. Morgan Stanley forecasts a full-year average of $2,900/t for 2026, well below current spot levels, implying a significant H2 correction. Fastmarkets similarly expects H1 firmness to give way to softening in the second half as a global surplus emerges — particularly if Chinese smelters, which hold substantial surplus metal behind a closed arbitrage window, begin exporting. The tension is between today's spot reality and tomorrow's fundamental forecast. (FACT: FocusEconomics, Morgan Stanley, 2026)
The zinc market is pricing supply risk, not demand strength. Buyers should not assume the current price level reflects genuine end-use pull — it reflects a structurally thinned spot market where cancelled warrants have removed material from accessible inventory. The key risk in H2 2026 is a sudden price correction if Chinese surplus metal is finally released onto the seaborne market. Buyers with fixed-price contracts at current elevated levels should consider hedging downside exposure. For spot buyers, the strategy is to secure volumes early where possible, as physical premiums are likely to remain elevated as long as cancelled warrant ratios stay above 10%.
