Zinc falls on weak steel demand; Nexa drops, Buenaventura holds
A drop in galvanised steel demand pushed zinc prices lower this week, exposing a divergence among Latin American mining equities as investors await clarity on second-half construction cycles.
Zinc prices eased into the weekend as weaker demand from the construction and manufacturing sectors offset declining warehouse stocks. London Metal Exchange cash zinc fell from $3,591 a tonne on July 16 to $3,549 a tonne the following day. The retreat extended to Asia, where Indian MCX zinc July futures dropped 0.57 percent to 375.15 rupees per kilo on Friday.
The price drift reflects cooling orders for galvanised steel rather than any sudden surge in mine supply. When builders delay projects or manufacturers slow purchases, demand for the rust-proofing metal drops. Although LME inventories have declined from 119,200 tonnes at the start of July to 111,725 tonnes, traders are currently focused on the demand side.
For equity investors, the softening tape created a clear split among Latin American mining stocks. Nexa Resources, a Brazil- and Peru-based producer heavily leveraged to zinc, closed at $12.19, down 3.02 percent on the day. Buenaventura, a more diversified Peruvian miner with significant gold and silver exposure, bucked the trend to close at $30.24, up 0.23 percent.
This divergence matters because portfolio managers often use these tickers as a shorthand for zinc risk in the region. Nexa’s pullback comes after a sharp rally from roughly $8.86 at the start of the year, suggesting investors are trimming exposure to the pure zinc play as momentum fades. Buenaventura’s resilience, after an 87.3 percent gain over the past 12 months, highlights how commodity mix can insulate diversified miners from single-metal price swings.
Latin America remains central to global zinc supply, producing roughly 3.5 million tonnes of unwrought zinc in 2024. Peru, Mexico and Bolivia rank among the world’s top ten producers, with Peru alone accounting for about 10 percent of global mine output in 2020. Because this metal ultimately serves the automotive and infrastructure sectors, the region's exports are leveraged to multiple macroeconomic narratives, from Chinese steel mills to United States industrial demand.
Prices remain elevated by historical standards, with Trading Economics pegging zinc near $3,528.60 a tonne, keeping Latin American mines economically attractive. However, the immediate direction for both the metal and its equity proxies now depends on whether construction pipelines re-accelerate in the second half of the year. Until then, zinc miners are likely to trade on company-specific fundamentals rather than broad commodity momentum.
