Zinc Hits 4-Year High as Global Market Shifts to Deficit

Key Facts

1Zinc prices have surged 31% since March to $3,966 a ton, driven by declining mine output and operational disruptions.

2The ILZSG revised its 2026 global zinc market forecast to a 19kt deficit from a previously expected 271kt surplus.

3Zinc's cash-to-three-month spread widened into a steep backwardation of over $190 per ton, signaling extreme physical tightness.

Amid escalating pressures on industrial metal supply chains, zinc prices have surged by 31% since March, reaching a four-year high of $3,966 per ton. This rally is primarily driven by declining mine output and operational disruptions, including fires and project delays, which have resulted in extremely thin physical liquidity across global markets.

According to reports, the International Lead and Zinc Study Group (ILZSG) has drastically revised its 2026 global market forecast to a 19kt deficit, reversing a previously anticipated surplus of 271kt. This structural shift has pushed zinc's cash-to-three-month spread into a steep backwardation of over $190 per ton, signaling intense competition among smelters for limited concentrate as treatment charges hit record negative levels.

While prices recently eased by 0.8% to $3,861 per ton according to available data, analysts suggest that high smelting costs will provide a strong floor for the metal. With current price data unavailable for a real-time snapshot, market participants are focusing on physical supply stability and previous industrial signals, such as the Manufacturing PMI data from Germany and the US (as of August 21, 2026), to gauge future demand trends.
