Copper Supply Chain Thermodynamics as a Leading Indicator of Geopolitical Instability

Every ton of refined copper carries two measurable costs: a financial cost denominated in US dollars on the London Metal Exchange (LME), and a thermodynamic cost measured in gigajoules (GJ) of energy consumed across mining, concentration, smelting, refining, and maritime transit. Under stable conditions, these two costs correlate closely. This paper identifies conditions under which they diverge and argues that persistent divergences between dollar cost and energy cost serve as leading indicators of geopolitical instability in the copper supply chain. Five categories of supply-chain chokepoint are examined: maritime (Hormuz, Malacca, Panama), chemical (sulphuric acid), processing (Chinese smelter concentration), institutional (Codelco, social license in Peru), and hydrological (Atacama desalination). Analysis of the 2026 Hormuz crisis, the concurrent sulphuric acid supply failure, and the structural divergence between Chinese and Western smelting costs demonstrates that the copper supply system is currently experiencing simultaneous stress at multiple nodes. The paper concludes that thermodynamic cost analysis offers a complementary framework to conventional commodity-price analysis for anticipating supply-chain failure and geopolitical realignment.
