Copper and silver have been intertwined for centuries, rooted in their shared mining origins. They often come from the same polymetallic ore deposits, meaning shifts in copper mining historically influenced silver supply. This structural link predates modern markets, embedding a deep connection based on geology and production.

Société Générale’s analysis shows this physical relationship translates into price behavior. Data since 1850 reveals a strong long-run correlation, with major exceptions only during crises like the 1980 Hunt brothers’ squeeze or the 2008 financial crash. Outside these events, prices generally move together.

The connection isn’t just geological. Silver is often a byproduct of copper smelting, tying its output to copper processing infrastructure. Advances in refining have improved silver recovery, further linking supply. While silver’s precious metal status can cause divergence, the core structural relationship remains intact.

Looking ahead, this historical tie offers a framework for analyzing commodity cycles. Investors watching copper demand for construction and manufacturing might gauge silver’s industrial trajectory. The link suggests that major copper price swings could still ripple through silver markets, barring another extraordinary shock.
