Zinc Hits Four-Year High As "Extremely Thin" Physical Supply Fuels Squeeze
Zinc has rallied 31% since March to $3,966, driven by declining mine output, operational disruptions, and limited supply outside China. The ILZSG revised its 2026 forecast from a 271kt surplus to a 19kt deficit, signaling structural tightness. Physical liquidity on the LME is at extremely thin levels, evidenced by steep backwardation ($190+ per ton) and negative treatment charges (−$110 per ton), which could trigger further smelter production cuts and deepen the squeeze.
