Spot tin on the London Metal Exchange trades at a premium to the three-month contract, the widest spread since the 2023 squeeze. Exchange stocks are down nearly 60% since June, yet the outright price has barely moved.
Spot tin on the London Metal Exchange is rising relative to forward prices. Friday's prompt price traded at a $670-a-ton premium to the three-month contract, a structure called backwardation. The spread is the widest since the 2023 squeeze, though far below the year-long backwardation of 2021.
Why spot supply is tight
Backwardation signals that metal available now is scarcer than metal for later delivery. The stocks that underpin LME contracts are down nearly 60% since June.
Tin is tiny next to copper and aluminum, so minor imbalances cause outsized moves, and it is routinely the most volatile LME metal. As short positions approach expiry, holders face pressure to find deliverable metal, which often fuels a scramble. Falling exchange stocks have also driven big backwardations in copper and aluminum in recent months.
Spread widens while price holds
However, the stress shows in the spread, not the outright price. The three-month price rose 0.1% to $46,700, while most other LME metals traded lower.
Tin's 52-week range is $36,752 to $57,760, so $46,675 sits roughly 19% below the top. Tin is down about 16% over three months, yet spot tightness is rising. Physical scarcity and falling outright prices can coexist when financial demand fades.
Bulls and bears weigh the squeeze
The bull case rests on sharply lower exchange stocks, squeezes that have recurred across metals, and tin's illiquidity, which can amplify any scramble for delivery. The bear case points to three months of falling outright prices, rising demand risk from electronics and rate hikes, and a spread still far below 2021's extreme. A squeeze can fade quickly if metal arrives.
Tin's main use is solder for electronics, which ties it to the chip cycle. Rates are also a headwind for industrial metals: a Fed hike in December looks nearly certain, according to the report.
The watch points are further LME inventory declines, the cash-to-three-month spread near expiry, and the Fed's Dec. 8-9 meeting.
