LME tin settled at $50,325/mt on June 28, holding above $50,000 for the fourth consecutive week. SHFE tin rose 0.27% to ¥425,060/mt, equivalent to approximately $59,000/mt at current exchange rates — the persistent SHFE premium signaling stronger physical demand in China than the LME price suggests. Tin is the most structurally bullish base metal in mid-2026. Its supply is concentrated in a handful of unstable jurisdictions, its demand is tied to the unstoppable growth of electronics miniaturization, and its inventories are too small to absorb a supply shock. The market has been living this reality since Myanmar's Man Maw mine suspended operations, and nothing in the June 2026 data suggests it is about to change.
The Myanmar supply disruption is now entering its second year. The Man Maw mine in Wa State — Myanmar's largest tin producer and historically the source of approximately 10% of global tin mine supply — was suspended for a formal resource audit in late 2024. The audit, ordered by the Wa State authorities who control the region, was initially expected to conclude within six months. As of late June 2026, the suspension remains in effect with no firm restart date. The impact on global tin supply has been severe: Myanmar's tin ore exports to China, which averaged approximately 4,000-5,000 tonnes of contained tin per month in 2023, have fallen to less than 1,000 tonnes per month in 2026. Chinese smelters, particularly in Yunnan province which borders Myanmar, have been forced to source concentrate from alternative origins — Australia, Bolivia, the DRC — at significantly higher cost.
Indonesia's export enforcement adds a second layer of supply constraint. The Indonesian government has tightened its export licensing requirements for tin, requiring producers to demonstrate compliance with environmental standards and domestic processing obligations before receiving export permits. The crackdown has reduced Indonesia's refined tin exports by an estimated 15-20% in 2026 compared to 2025 levels. PT Timah, Indonesia's state-owned tin producer and the world's largest integrated tin miner, has seen its export volumes decline as the new licensing requirements create administrative delays. Unlike Myanmar's suspension, which could reverse if the Wa State audit concludes, Indonesia's enforcement represents a structural shift toward tighter regulation of the country's mineral exports — a policy direction that is unlikely to change regardless of the commodity price.
The concentrated nature of tin supply makes it uniquely vulnerable to disruption. Unlike copper, where production spans dozens of mines across multiple continents, tin's production base is narrow: Myanmar, Indonesia, China, and Peru account for approximately 80% of global mine output. The Man Maw mine alone represented roughly 10% of global supply before its suspension. The CRU Group noted in its 2025 tin market assessment that the metal's small market size — approximately 380,000 tonnes of refined production per year globally — amplifies geopolitical risk. A 10,000-tonne supply disruption, which would be a rounding error in the 25-million-tonne copper market, represents nearly 3% of global tin supply.
Demand for tin is structurally growing, driven by three secular trends. First, semiconductor and electronics miniaturization: tin solder is essential for circuit board assembly, and the number of solder joints per device continues to rise as electronics become more complex. A modern smartphone contains approximately 1-2 grams of tin; a data center server rack contains 1-2 kilograms. The global semiconductor industry is projected to grow at 6-8% annually through 2030, driving proportional growth in tin solder demand. Second, the energy transition: solar panels use tin in soldered connections, and the average EV contains approximately 2-3 kilograms of tin compared to 0.5 kilograms in an internal combustion vehicle. Third, tin's substitution into lead-free solders, driven by environmental regulation (RoHS, REACH), continues to expand tin's addressable market as lead is phased out of electronics manufacturing.
The International Tin Association (ITA) estimates that the global refined tin market will remain in structural deficit through at least 2027. The cumulative deficit over 2024-2026 is estimated at approximately 25,000-30,000 tonnes, which has been met by drawing down exchange and non-exchange inventories to critically low levels. LME tin stocks sit at approximately 2,500 tonnes — representing less than three days of global consumption. SHFE tin stocks are similarly depleted. The inventory buffer that historically absorbed supply disruptions has effectively been exhausted.
The CRU Group's base case, published at the November 2025 International Tin Conference, projects tin prices in the $36,000-$40,000/mt range through 2026 under the assumption that Myanmar's Man Maw mine returns to partial production within six months. That assumption has not materialized. A more realistic base case, with Myanmar supply remaining constrained and Indonesian exports tightening, supports prices in the $45,000-$52,000/mt range. The bull case — a complete loss of Myanmar supply combined with a surge in semiconductor demand driven by AI infrastructure buildout — could push tin to $60,000-$65,000/mt. The bear case — an unexpected resolution of the Myanmar audit and normalization of Indonesian exports — would bring prices back to $38,000-$42,000/mt. The probability distribution is skewed to the upside given the depletion of inventory buffers.
Analyst views are uniformly bullish but cautious on entry levels. The ITA's market report for mid-2026 describes the supply situation as 'precarious' and notes that even a modest demand recovery would accelerate the inventory draw. CRU's analysts have raised their 2026 average price forecast to $42,000/mt, up from $36,000 at the start of the year. Crucially, the analysts that were bearish on tin in 2024 — arguing that high prices would incentivize new supply — have been proven wrong. The supply response has been negligible because tin projects, like copper projects, face multi-year development timelines. The Alphamin Bisie mine expansion in the DRC is the only major new supply expected before 2028, and it will add only approximately 5,000-8,000 tonnes per year — insufficient to close the deficit.
For the week ahead, tin traders are focused on two signals. First, any news from Wa State on the Man Maw audit status. The Wa authorities have been silent since April 2026, and the market interprets silence as continued deadlock. Second, Indonesian export data for June, due in the second week of July, will confirm whether the licensing crackdown is intensifying or easing. Tin is a market where the fundamentals point unambiguously higher, but the small market size and illiquidity mean that a sudden rally or correction can happen quickly and without warning.
Tin buyers are in the most difficult procurement position of any base metal. Global inventories are critically low, supply is concentrated in unstable jurisdictions, and the demand growth trajectory from electronics and energy transition is secure. The traditional buyer response to high prices — wait for a correction — has been punished repeatedly over the past 18 months. Three recommendations: First, accept that tin above $50,000/mt is the new normal until Myanmar supply returns or a recession destroys demand. The probability of Myanmar supply returning in H2 2026 is low, and the probability of a recession deep enough to cut semiconductor demand is also low. The logical conclusion is that tin prices are likely to stay elevated or move higher. Second, hedge your exposure. A simple call spread — buy a $55,000 call, sell a $65,000 call — would protect against a supply-shock spike to $60,000+ while limiting premium cost. The options market in tin is thin, so work with your bank early to structure this. Third, investigate solder recycling and recovery programs within your supply chain. Secondary tin from recycled solder already accounts for approximately 30% of global supply, and increasing this share is the most realistic way to reduce primary tin dependence without waiting for new mines that won't arrive until 2028 or later. If you have not audited your tin supply chain's geographic exposure to Myanmar and Indonesia, do it now — a further escalation in either country would cut off supply with minimal warning.
