Global refined zinc market surplus set to widen through 2026

Zinc

The global refined zinc market surplus is forecast to widen sharply as supply growth outpaces a modest demand recovery. According to ILZSG projections, refined zinc will move from an 85,000t surplus in 2025 to a 271,000t surplus in 2026. As a result, the global refined zinc market surplus will increasingly shape treatment charges, pricing power and smelter utilisation, especially outside China. The refined zinc balance already showed a 47,000t surplus in the first half of this year, confirming the shift from earlier tightness.

However, demand for refined zinc is still expected to grow, even under pressure from weak construction and patchy industrial activity. ILZSG forecasts refined zinc use to rise by 1.1pc to 13.71mn t in 2025, led by a 1.3pc increase in China on stronger vehicle output. Meanwhile, European demand should finally stabilise, rising by 0.7pc after three years of contraction, with France, Germany, Norway and Poland offsetting declines in Italy and Russia. Emerging markets including India, Saudi Arabia, Thailand and Vietnam will also support consumption, even as Brazil and South Korea lag.

Supply expansion drives global refined zinc market surplus

The global refined zinc market surplus is driven primarily by a clear upturn in mine and smelter supply. ILZSG expects zinc mine production to rise by 4.6pc to 12.51mn t in 2025, with 5pc growth outside China. Therefore, higher output from Bosnia and Herzegovina, Ireland, Portugal, Russia and Sweden joins gains in China, South Africa, Peru and the DRC. Further mine growth in 2026 will be underpinned by the reopening of Aljustrel in Portugal and higher production in Australia, Brazil, the DRC and China.

At the smelter level, refined zinc output is forecast to rise by 2.7pc to 13.8mn t in 2025, then by 2.4pc to 14.13mn t in 2026. The biggest driver is China, where new capacity is being commissioned and is expected to lift output by 6.2pc in 2025. Meanwhile, European production receives a structural boost from Boliden’s 150,000 t/yr expansion at the Odda smelter in Norway. These increases will outweigh declines in Italy, Japan, Brazil, Canada, Mexico and South Korea, locking in the global refined zinc market surplus unless demand surprises to the upside.

Refined lead market also tips into surplus

The surplus story extends beyond zinc, with refined lead also moving into a looser balance. ILZSG projects refined lead supply to exceed demand by 91,000t in 2025 and 102,000t in 2026. Demand for refined lead is still expected to rise by 1.8pc this year to 13.25mn t, and by 0.9pc to 13.37mn t in 2026, driven mainly by Europe, Vietnam and the US. However, supply will grow faster, with refined lead output seen rising by 2pc to 13.34mn t in 2025 and by 1pc to 13.47mn t in 2026, supported particularly by Brazil and India. As a result, both zinc and lead markets are heading into a multi-year period of oversupply.

The Metalnomist Commentary

The global refined zinc market surplus projected for 2025–26 signals a prolonged phase of buyer’s market dynamics in galvanising and alloy segments. Smelters with high energy costs or weaker integration into mine supply will face the greatest margin pressure as treatment terms and premiums adjust. For lead, surpluses underline the importance of battery recycling economics and regional policy support, especially as EV and energy storage value chains reshape traditional lead-acid demand.
