Zinc Steadies as LatAm Miners Diverge on Friday

On Friday, September 11, 2026, zinc trading was influenced by a mix of soft industrial demand and zinc's crucial role in rust-proofing steel. The benchmark settlement decreased by 0.26% to US$3,865.15 per tonne, while a later New York quote indicated a price of US$4,035.66 per tonne, marking a 0.45% increase. Latin American zinc proxies, however, did not follow the metal's price.

Nexa Resources, a Peru/Brazil-focused zinc miner, experienced a 1.29% increase, closing at US$13.31, while Buenaventura, a Peruvian miner with zinc exposure, rose by 0.56% to US$34.04. The driving forces behind this divergence were galvanised-steel and construction demand, as zinc is primarily employed to protect steel from corrosion.

For foreign investors, the disparities between zinc and miner shares serve as a reminder that proxy trades entail company-specific risks. The majority of global zinc supply remains centered in Peru, Bolivia, and Mexico, and their miners will continue to be of interest for those monitoring infrastructure spending in the Americas.

The zinc market experienced a cooling effect on Friday, September 11, 2026, with the benchmark settlement falling 0.26% to US$3,865.15 per tonne. This decline suggests that industrial buyers were hesitant, rather than reacting to a significant shift in fundamentals. Later in the day, a New York quote of US$4,035.66 per tonne demonstrated that some traders remained interested in purchasing the metal.

The discrepancy between these two quotes highlights a market without a clear direction. While zinc itself declined in the main settlement, the shares of two Latin American miners increased, indicating that equity investors may be pricing a stronger demand outlook for zinc than the metal's price alone suggests. The cautious outlook among Latin American mining stocks, despite the benchmark price's dip, suggests that investors are not overly worried about the metal's soft settlement.

Peru, Bolivia, and Mexico are the primary sources of zinc in the region, making regional policy and logistics important factors for global buyers. Nexa Resources, a Peru/Brazil-focused zinc miner, is the most direct listed proxy for investors seeking exposure to Latin American zinc. Buenaventura, on the other hand, offers zinc exposure in addition to precious metals, and its share price can be affected by movements in gold and silver prices.

The divergent performance of Nexa Resources versus the zinc metal itself underscores the fact that no proxy is perfect. Monitoring mine output news from Peru, Bolivia, and Mexico is crucial for understanding regional supply dynamics, as disruptions in these countries can quickly impact galvanised-steel supply chains. The outlook for zinc will depend on whether construction demand strengthens sufficiently to absorb supply from Latin America.

While the New York quote above US$4,000 per tonne suggests the market is not yet convinced that a deeper decline is imminent, the benchmark settlement indicates that buyers are still cautious.
