Chinese Zinc Exports Ease Pressure on London Shorts as Prices Hit Four-Year High

London: Chinese refined zinc exports are providing some relief to traders betting on lower prices in the London market, but the global zinc market remains under significant pressure as tight exchange inventories and strong investor positioning push prices higher.

Three-month zinc on the London Metal Exchange (LME) climbed to a fresh four-year high of $3,858 per tonne on August 25, highlighting the difficulties faced by short-position holders who had expected prices to weaken this year.

China Emerges as a Key Source of Supply

China has traditionally been a major importer of refined zinc, but rising domestic smelter capacity and attractive international prices have encouraged Chinese producers to export more metal. The shift has created an additional source of supply for the LME market, particularly through warehouses in Hong Kong.

The exports are helping replenish stocks available for delivery and could reduce some of the immediate pressure on traders holding short positions. However, the quantities remain relatively limited compared with the scale of the global zinc market.

Global Production Outpaces Demand

The rally is occurring despite signs of a broader refined-zinc surplus. Global zinc consumption increased by only about 1.5% in the first part of 2026, while refined production grew by approximately 3.5%, with China accounting for much of the increase.

The problem for bearish traders is that surplus metal is not evenly distributed. LME warehouse inventories remain relatively tight, while zinc stocks accumulated inside China are much higher. This geographical imbalance has helped keep readily available metal in London under pressure.

Record Bullish Positioning Adds to Volatility

Investor positioning is another major factor supporting zinc prices. Funds have accumulated more than 110,000 tonnes worth of net long positions, the highest combined bullish position since the LME began publishing its market-participant positioning data in 2018.

At the same time, treatment charges for zinc concentrates have fallen sharply, squeezing smelter margins and raising questions about whether Chinese producers can maintain their current production rates.

Outlook Hinges on Chinese Supply

Chinese exports could continue to provide relief to the London market if the price incentive remains strong. However, analysts and traders are watching whether Chinese smelters can sustain output amid weak processing economics.

For now, the combination of limited LME inventories, strong speculative buying and constrained mine supply continues to favour higher zinc prices. Increased Chinese exports may ease the squeeze on short sellers, but they have yet to fundamentally change the market’s bullish momentum.
