Tin is the least-discussed critical metal essential to every electronics supply chain — used as solder in virtually all semiconductor packaging — and decades of under-investment in new mine supply have collided with an Indonesian export collapse and a Myanmar feedstock shortage to push the market into its first deficit since 2021 and prices to record highs.

| Indicator | Score | Reading |

| Evidence Strength higher is better · high confidence | 55/100 | Corroborated by company disclosures, an industry association, and financial press, but reliant on one specialist trade body for supply-share statistics. |
| Commercial Proximity higher is better · high confidence | 85/100 | Established producers already earn at scale on record prices; the wedge is the deficit itself, not a new product. |

| Crowding Risk lower is better · high confidence | 75/100 | A small, thin market that has become the object of intense speculative and financial-flow attention, well beyond its physical size. |
| Reflexivity Risk lower is better · high confidence | 64/100 | A small market where single-country policy headlines and financial (largely Chinese futures) flows dominate short-term price formation more than fundamentals. |
