Strategic Analysis: The zinc spot market has not shown significant improvement, with downstream consumption indicating signs of entering a seasonal lull. Affected by invoice quotas, spot supply in the market is relatively tight, leading traders to hold firm on prices and be reluctant to sell. The supply side continues to evolve favorably. Following an explosion at a smelter in Kazakhstan, a fire at a Peruvian smelter has caused partial facility damage and a temporary operational halt, potentially reopening export opportunities. The downward trend in ore prices persists, with imported ore offers at -$60 per tonne and metal content priced separately. Domestic zinc concentrate treatment charges (TC) are expected to decline further, compressing overall smelting profits. Consequently, ore costs are providing substantial support to zinc prices. Energy supply issues in Peru have not yet materially impacted ore supply, but risks remain. On the consumption side, short-term factors are relatively bearish. Domestic inventories have not entered a significant destocking phase, exerting some downward pressure on prices. Market attention is on whether changes in US-Iran relations could alter the current pessimistic consumption outlook.
Risks: 1. Unexpected disruptions to overseas ore supply. 2. Domestic consumption falling short of expectations. 3. Liquidity changes exceeding forecasts.
