Macro Headwinds and Supply Constraints in a Tug of War, Tin Prices Mainly Move Sideways [SMM Tin Morning Meeting Minutes]

SMM Tin Morning Meeting Minutes, August 31, 2026

Market review: The most-traded SHFE tin contract saw heavy turnover near 427,000 yuan early last week. It then pulled back as PCE data came in slightly above expectations, the probability of a September Fed rate hike rose, and macro sentiment weighed on the market. Mid-week it dipped to near 417,000 yuan, turning the 420,000-yuan round level into an immediate battleground. Overall, after a rapid rise, prices retreated and then consolidated on a subdued note, with the trading range roughly between 417,000 and 430,000 yuan. In the tin ingot spot market, the off-season pattern continued. Buying interest from downstream and end-user enterprises was limited. At high futures levels, actual transactions were sluggish. The mid-week pullback only triggered a small release of rigid-demand point-pricing and restocking orders. The mainstream quotation range was concentrated at 425,000–428,000 yuan, and almost no transactions were done above 430,000 yuan. Overall trading was dominated by cautious rigid demand.

Market forecast:

On the international macro front, the latest US inflation data came in slightly above expectations, core inflation accelerated MoM, expectations for US Fed interest rate hikes rose marginally, and a stronger US dollar weighed on the nonferrous metals sector; however, holding rates steady remains the base case, and the tone of the Jackson Hole central bank symposium will be key for the near-term policy path. Although tin inventories outside China remained at historical lows, they rebounded during the week, and the squeeze support from low inventories eased at the margin. China’s tin market generally displayed a pattern of supply constraints providing a floor and repeated off-season demand weakness. On the supply side, the tail end of the rainy season in Myanmar’s Wa State limited the release of tin concentrates. Production resumptions progressed more slowly than expected, and full-year supply remained constrained. Yinman Mining’s production suspension has not yet been lifted, causing regional reductions in China’s mine supply. Indonesia’s export controls continued and its recovery remained limited. Raw material tightness at smelters eased somewhat but was not fundamentally relieved. On the demand side, the traditional consumption off-season and high tin prices once suppressed downstream purchasing, and social inventories still faced upward pressure; however, after prices pulled back during the week, solder producers saw more orders, restocking willingness improved, and spot transactions recovered somewhat. In summary, the tin market is locked in a tug-of-war between macro headwinds and hard supply constraints. It lacks a clear one-sided driver in the short term. Tin prices are expected to continue moving sideways next week. If macro policy signals turn hawkish, prices may test lower support; if inventory destocking and downstream restocking continue, downside room will be limited. We suggest investors maintain a range-trading approach, focusing on macro policy signals, inventory changes, and policy developments in Wa State and Indonesia, and avoid chasing rallies or selling into declines.
