Silver and its ascent is a structural repricing driven by the thermal wall of AI data centres. But as global markets panic, South Africa’s mining sector faces its own reality check of infrastructure bottlenecks and missed renewable targets. Silver’s historic rally was supposed to stop at $75.
At least that’s what an obviously AI-generated video on X tried to convince me of while I was eating next-day trifle – the official breakfast dish of the Day of Goodwill. There was an apparent secret deal among institutional bankers to cap the price. What we are witnessing is not just a speculative mania, but what analysts are calling a “structural repricing” of the metal.
It is a collision between the thermodynamics of artificial intelligence and a financial system caught on the wrong side of a physical shortage. For decades silver traded as a safe-haven asset tethered to interest rates. That logic has fractured.Silver is now trading as a critical industrial component for the “AI factory”.

The driver is simple physics. As data centres transition to processing large language models, the chips powering them are simply getting too hot for traditional soldering. The industry solution is silver sintering – using pastes of nanoscale silver particles that fuse at the atomic level.
This shift has created perfectly inelastic demand. The logic is brutal: the difference between using expensive silver versus cheap solder is irrelevant if the cheaper option risks a thermal failure, which is whyNvidia uses about 3g of silver in each of its H100 AI processors. Tech giants cannot afford to let a multibillion-dollar data centre melt to save a few cents on metal.
This is a story of the physical reality of the cloud – a massive industrial edifice constructed from specific geological inputs. McKinsey’sGlobal Materials Perspective 2025puts hard numbers to this buildout. It projects that global data centre capacity could expand by 2.7 times from 2025 to 2030.
While silver handles the heat, copper handles the power. The firm estimates that data centres alone could account for up to 3% of global copper demand by 2030. This demand shock is hitting a market where supply is already constrained, contributing to what they call a “cyclical reset” where value pools are shifting away from traditional bulks like steel and coal towards energy-transition metals.
