Today’s Focus
Zinc-linked shares rose on Monday as Latin American markets sold off. Nexa Resources, which runs zinc mines and smelters in Peru and Brazil, gained 1.39% to US$11.64.
Buenaventura, a Peruvian gold, silver and base-metals group, rose 1.86% to US$28.44. The two names moved against the regional trend.
Brazil’s Ibovespa fell 13.88% on the same day, yet Nexa, which has Brazilian operations, still closed higher.
What matters today. Nexa’s gain on a day of Brazilian turmoil shows how a dollar-earning metals producer can behave differently from domestic Brazilian shares.
01 The session in one read
Zinc-related shares finished Monday, 26 October 2026, higher. Nexa Resources rose 1.39% to US$11.64, and Buenaventura gained 1.86% to US$28.44.
Zinc is used mainly to galvanise steel, which protects it from rust. Its price depends on construction, car production and mine supply.
We have no verified zinc price for the session, so we do not state one.
Assessment — Producers rise, no price signal MEDIUM
The evidence points to producer shares trading on dollar earnings and Peruvian exposure rather than on Brazil’s shock. Without a verified metal price, the move cannot be tied to zinc itself. The variable to watch is whether Nexa keeps rising if the Brazilian real slides further.

The session read
The Ibovespa eased 13.88%, with breadth negative — 1 of 4 names higher. BVL PERÚ led, while IPSA lagged.
03 What moved it
Brazil’s political shock hit domestic-facing shares hardest. Nexa earns US dollars from metals, so it fell less than banks and consumer names.
The dollar jumped 8.79% against the real, which lowers Nexa’s local costs in dollar terms.
US markets were calm, with the S&P 500 up 0.70% and the US dollar index, a gauge of the dollar against major currencies, up 0.22%.
04 The Latin American read
Peru is a major zinc producer, and Nexa operates mines there as well as in Brazil. That makes the group a regional proxy for the metal.
Brazil’s market fell sharply, but Peruvian mining shares in New York held up. That suggests investors separate metal producers from Brazilian domestic risk.
Chile and Argentina also fell on Monday, with the IPSA down 1.59% and the Merval down 3.0%.
05 The names to watch
Nexa Resources is the most direct listed zinc proxy in the region, with operations in Peru and Brazil.
Buenaventura offers wider Andean mining exposure, including gold and silver, so zinc is only one of its drivers.
06 The outlook
The zinc outlook depends on construction demand, mine supply and the dollar. None of these changed on Monday in our verified data.
The Federal Reserve meets this week, and a firmer dollar would usually weigh on metals.
07 What to watch
- Federal Reserve meeting: Rate guidance could move the dollar and base metals.
- Nexa: Whether it holds above US$11.45, Monday’s low.
- Brazilian real: A slide could affect Nexa’s Brazilian costs and earnings.
- Peru mining shares: Whether they keep rising while Brazil is under pressure.
Frequently Asked Questions
What is Nexa Resources?

Why did zinc shares rise while Brazil fell?
Producers earn dollars from metals, and Brazil’s shock was about its politics and currency, not about metal demand.

Zinc is mainly used to coat steel so it does not rust, which links it to construction and manufacturing.
Does this wrap state a zinc price?
No. A verified zinc price was not available for the session, so only listed producers are shown.
