Tin prices fell significantly across major global markets on September 11, 2026, as expectations for aggressive US Federal Reserve interest rate hikes weighed on risk sentiment and dampened demand from downstream electronics and solder manufacturers. On the Shanghai Futures Exchange, the most-traded tin contract opened at 418,900 yuan per metric ton during the daytime session on September 11, reaching a high of 419,790 and a low of 408,030 before closing at 410,290 yuan/mt. This represented a decline of 15,480 yuan/mt, or 3.64 percent, from the previous close of 425,770 yuan/mt on September 10.
The weakness extended into the night session, which closed at 404,090 yuan/mt on September 12 at 02:30, marking an additional pullback of 1.51 percent from the previous close and breaking below the psychologically important 410,000 yuan level for the second consecutive session. London Metal Exchange tin similarly declined, closing at $53,200 per metric ton on September 11, down $915/mt or 1.69 percent from $54,115/mt on September 10, with trading volume of 1,080 lots. Positioning data showed notable adjustments in market positioning.
Bulls reduced their combined positions by 1,170 lots during the daytime session, while bears cut net positions by 1,036 lots. However, leading institutions added notably to short positions, reflecting bearish sentiment. Open interest in the most-traded contract remained near 35,000 lots.
The sharp selloff was primarily attributed to macroeconomic headwinds. The US released August Consumer Price Index data on September 11, showing a 3.4 percent year-over-year increase in line with expectations. However, core CPI rose 0.3 percent month-over-month, marking the highest monthly increase since May.
CME FedWatch tools indicated that the probability of a 25 basis point Federal Reserve rate hike at the September 15-16 FOMC meeting jumped to between 86.5 and 90 percent. In response, the 10-year Treasury yield touched 4.9915 percent intraday and closed at 4.97 percent, while the 30-year yield broke above 5.42 percent, reaching a 19-year high. The US dollar index edged up 0.07 percent to 99.122, maintaining support above the 99 level.
Crude oil prices pulled back from recent highs, with WTI settling at $100.05 per barrel, down 2.37 percent, and Brent crude at $104.61, down 2.81 percent, as the Gulf Cooperation Council and Iran planned consultations on passage through the Strait of Hormuz. Fundamental factors also weighed on tin sentiment. China's tin social inventory shifted to destocking on September 11, while LME tin inventory hit a fresh stage low.
The Ministry of Natural Resources announced that China ranks first globally in reserves of 14 minerals, including rare earths, tungsten, and tin. However, downstream solder and electronics enterprises turned more cautious in procurement amid stagflation trading concerns tied to elevated oil prices and expected interest rate hikes. On the supply side, Myanmar's Wa State exported 4,569 metric tons in physical content of tin concentrates to China in July, equivalent to 1,077 metric tons of metal, representing a 27 percent month-over-month decline.
Indonesia's Timah saw August exports to China recover to the expected range, providing some stability to supply flows. Technically, the failure to hold above the 410,000 yuan level in both the daytime and night sessions confirmed a breakdown of this key support level. Market participants will monitor the 400,000 round-number level as the next critical support target.
