Do you feel the global economy is heading in a positive direction for commodity prices?

Zinc prices increased 2.0% on September 25, 2026, settling at US$4,060 per tonne. Tight concentrate supply supported the valuation despite ongoing soft demand from Chinese construction and infrastructure sectors.

Why it matters

Supply constraints provided a price floor for the metal, helping values recover from recent lows even as high exchange inventories and weak industrial demand from Chinese galvanisers capped gains.

The LME zinc price rose to US$4,060 per tonne, a 2.0% increase from the previous day. Total LME zinc stocks currently sit at 121,600 tonnes.

The players

Nexa Resources

Nexa Resources is a significant global zinc mining and smelting company with operations in South America.

Buenaventura

Buenaventura is a major Peruvian precious metals mining company that also maintains significant interests in base metal production.

Boliden

Boliden is a major European metals company currently involved in a corporate deal with Nexa Resources.

The details

Market activity reflected a tug-of-war between sellers attempting to limit downward pressure due to supply constraints and buyers avoiding aggressive purchases due to elevated stocks. While Peruvian production grew in the first quarter, the broader market remains sensitive to industrial demand signals from China.

Q1 2026 saw Peru national zinc production grow by 2 percent.
September 9, 2026, marked a previous zinc high of US$4,186 per tonne.
September 24, 2026, saw the zinc cash price close at US$3,981 per tonne.
September 25, 2026, was the date the zinc price reached US$4,060 per tonne.
Early 2027 is the anticipated closing date for the Boliden-Nexa deal.

Market Dynamics

Zinc pricing remains tethered to the 2026 Q1 Peruvian production growth levels as the industry balances output with fluctuating demand. This movement mirrors a broader shift in base metal markets that are attempting to find a price floor amidst volatile industrial consumption cycles.

Individual investors holding mining equities may see volatility as the market reacts to shifting inventory levels and future demand projections. Diversified portfolios with exposure to base metals are currently being recalibrated based on these supply-demand signals.

The takeaway

Zinc prices are currently supported by supply-side tightening despite headwinds from cooling construction demand. Investors should watch Chinese industrial data closely, as it remains the primary catalyst for a potential return to price levels seen earlier this month.
