Fundamentally, the resonance between minerals, smelting, and inventory is exacerbated by the combination of financial factors.
Supply side:
Mining sector: Supply gap continues to widen
Geopolitical ‘black swan’: The escalation of the situation in the Middle East directly blocks the external transportation channels of Iranian zinc mines, with an estimated monthly impact of about 15000 to 20000 tons of metal in the market;
Domestic mining production reduction: Several small and medium-sized mines in major production areas such as Inner Mongolia and Yunnan have gradually stopped production due to safety and environmental inspections and declining grades, resulting in a significant decrease in daily production of domestic mines compared to the previous period;
Imported ore ‘quantity reduction and price increase’: The transaction price of processing fees for imported zinc concentrate in August has fallen to -117.50 US dollars per ton, which means that smelters not only cannot receive processing fees, but also need to pay fees to the mining end. This is the first time since 2008 that there has been a sustained negative processing fee, directly reflecting the extreme level of shortage in the mining end.

Smelting end: Negative processing fees force production reduction
Under the dual pressure of high raw material procurement costs and low prices of by-products such as sulfuric acid, more than half of domestic smelters are already in a cash flow deficit state;
According to incomplete statistics, it is known that the total annual production capacity of refineries involved in maintenance and planned production cuts in September exceeded 800000 tons. It is expected that the refined zinc production for the month will decrease by 25000 to 30000 tons compared to the previous month, and the supply contraction is moving from expectations to reality.
Inventory end
LME zinc registered warehouse receipts have dropped to below 100000 tons, the lowest level in nearly three years.
SHFE inventory decreased by 9497 tons per week to 102672 tons, and the destocking slope accelerated.
comprehensive analysis
The internal and external markets have formed a resonance upward pattern. A structurally strong market trend where the supply and demand fundamentals are transmitted and confirmed layer by layer from the mining end to the smelting end. Above 27000 yuan belongs to the high valuation area, with a high risk of chasing after high prices. It is expected to experience strong fluctuations at high levels and intensify volatility.
