China’s Acid Ban: The Hidden Trigger for Silver’s Next Squeeze
Most investors watching silver right now are focused on geopolitical tensions, safe-haven demand, and the green energy transition. But a potential development out of Beijing over the next few weeks could be the most consequential supply shock nobody in the silver market is talking about yet.
According to industry reports, China could be set to ban exports of sulphuric acid starting next month. On the surface, that sounds like a chemicals story, but it is not; it is a silver story.
The connection nobody is making is that sulphuric acid is the lifeblood of copper mining. The heap leach process, dominant across Chile, Morocco, and Indonesia, works by pouring acid over crushed ore to dissolve the copper out. No acid could mean no copper. China supplied 4.6 million tonnes of it in 2025, with 32% going to Chile alone, and now that supply could be gone.
Less copper mined means less silver produced. Approximately 70% of newly mined silver is a byproduct of copper mining. When copper output slows, silver supply slows with it and with the Strait of Hormuz disruption already squeezing the elemental sulphur needed to manufacture acid independently, copper miners in these regions have nowhere left to turn.
The silver market was already running a structural deficit, with 2026 marking the sixth consecutive year demand has exceeded newly mined supply. Now add a structural reduction in byproduct silver from acid-starved copper mines. Industrial buyers who cannot substitute away from silver in solar panels and EVs may find themselves competing for whatever physical metal remains. That competition is what could turn a supply deficit into a price event.
Whether or not the Middle East conflict resolves, the structural damage to copper mine acid supply chains means less silver is coming out of the ground. Traders looking to get ahead of that move may want to consider these two example silver setups.

Example 5000-ounce Silver Futures Options Strategy
For example purposes only, one could purchase the December 2026 Silver futures $100.00 call option while selling a December 2026 $110.00 call against it. This bull call spread costs $7,500 plus commissions and fees, with a maximum gain of $50,000, less your initial cost, if silver futures close above $110.00/oz at expiration on November 24, 2026. We believe this strategy offers a low-risk, high-reward profile.
We also see value in systematically purchasing the 100-ounce silver contract at regular intervals, layering into a position over time to potentially average in ahead of the next rally. The 100-ounce Silver futures offer a pocket-sized product with full-sized potential.
