Tin, the Forgotten Metal of the AI Era: Three Supply Bottlenecks Collide with Solder Demand in Every Server
The small, concentrated tin market enters a deficit: Myanmar, Congo, and Indonesia choke supply while the AI hardware boom boosts solder demand, enriching pure-play miners.

Causal chain: Myanmar: sluggish restart of Man Maw mine → Indonesia: licensing turmoil and depleting deposits → Congo: Bisie in the shadow of M23 conflict → AI hardware boom drives solder consumption → Deficit in a small market, inventories near lows → Tin prices remain structurally elevated → Scarce pure-play tin miners expand margins
What this thesis rests on
Each one is a statement that has to be true. We go back to every live thesis on a schedule and check these against public sources, so each leg carries either what we found or the date we look next.

The Invisible Metal of Electronics
Tin represents one of the smallest and most neglected metal markets globally: annual worldwide consumption stands at roughly 370,000–380,000 metric tons, approximately one-hundredth the size of copper. Roughly half of this demand is consumed as solder—the indispensable conductive glue holding together every printed circuit board, from smartphones to AI accelerator clusters. A market of this miniature scale lacks buffers: a disruption of merely a few percentage points of global supply suffices to tip the physical balance into acute deficit.
