Silver depends on two Metals that just fell

Global silver supply is facing structural headwinds due to declining mine output from lead and zinc operations, where 73.9% of world mined silver is produced as a byproduct. Data from the International Lead and Zinc Study Group (ILZSG) revealed that first-half 2026 world zinc mine production dropped 2.6% while world lead mine output fell 3.0%, concentrated in major operations like Antamina in Peru and Garpenberg in Sweden. Furthermore, Chinese spot treatment charges for imported zinc concentrate dropped to a record low of minus $117.50 per dry tonne, signaling severe concentrate shortages. Because only 26.1% of global silver originates from primary silver mines, higher silver prices cannot easily incentivize new output from lead and zinc operators. This byproduct dependency constrains the market's ability to balance its structural deficit, projected by Metals Focus and the Silver Institute at 46.3 million ounces for 2026—marking a sixth consecutive year of shortage. Although Western visible inventories in London vaults and COMEX have not yet reflected physical tightness, the supply-side bottleneck provides strong underlying bullish fundamentals.
