LME three-month tin traded at $50,325/mt on June 27, consolidating near the stratospheric levels that have made tin the best-performing base metal of 2026. The contract touched an all-time nominal high of $58,750/t earlier in June and is up 35% year-to-date and 49% year-on-year, according to TradingEconomics data. The rally has been driven by a near-perfect storm of supply destruction and demand acceleration from the semiconductor and AI sectors.
Indonesia — the world's largest refined tin exporter — saw exports plunge over 40% year-on-year to just 3,246 tonnes in May 2026, according to Indonesian trade ministry data. The collapse follows President Subianto's order to close approximately 1,000 illegal tin mines in Sumatra and ongoing bottlenecks in the export licensing system. Crux Investor estimates the crackdown could remove up to 80% of Bangka-Belitung's output from the global market. LME time-spreads have flipped into backwardation, signaling acute near-term physical scarcity — buyers are paying a premium for immediately available metal over future delivery.
On the supply side, Myanmar — the world's third-largest tin producer with reserves of 700,000t — remains offline. Mining at the Man Maw operation in Wa State has been suspended since August 2023, and while the International Tin Association (ITA) reported in mid-2025 that several operators had secured three-year mining permits, BMI notes that shipments have stabilized at only about 1,300 tonnes of tin-in-concentrate per month, a fraction of pre-suspension levels. The ITA has stressed that recent price spikes are partly driven by speculative investor activity, particularly on the SHFE, but acknowledges the market is in a prolonged structural deficit.
Demand is the multiplier. Tin's primary use is solder in semiconductors and PCBs, and the global semiconductor recovery that began in mid-2023 is accelerating. Industry players cited by TradingEconomics expect tin demand for AI servers to triple by 2030. Procurement Resource reports tin prices in Asia above $55,000/t in April 2026, driven by tight ore availability and strong demand from advanced semiconductor packaging. BMI revised its 2026 average tin price forecast to $45,000/t from $35,000/t in February. Crux Investor's base case sees $36,000–40,000/t through 2026, but the conservative scenario — with some Myanmar supply returning — is now outdated given the severity of the Indonesian crackdown.
Tin procurement has entered crisis mode. Solder buyers and electronics manufacturers need to act immediately. The Indonesian export collapse shows no sign of resolution — licensing bottlenecks and the illegal mining crackdown are structural, not temporary. If you buy tin on spot, you are competing with semiconductor manufacturers who can absorb price increases more easily than smaller fabricators. For Q3 and Q4 volumes, secure contracts now at whatever premium is required. Explore secondary supply channels: Chinese smelters are still producing but facing concentrate shortages; consider direct relationships with Peruvian and Bolivian suppliers. Inventory hedging is essential — the backwardated LME curve means holding physical stock is cheaper than buying forward. Revisit solder specifications: reducing tin content marginally (e.g., from SAC305 to SAC105 where technically feasible) can lower exposure without compromising performance.
