Zinc Tops US$4,100 in London as Nearby Supply Tightens

Zinc prices surged on August 26, 2026, with LME cash zinc settling at US$4,107 per tonne, up 3% from the previous day. The backwardation of US$174 indicates tight supply. Nexa Resources fell 1.52% to US$15.58, while Buenaventura rose 0.67% to US$36.18. Supply tightness in Latin America, particularly from Nexa's Cajamarquilla plant, contributed to the price increase.
