Tin prices experienced a significant decline on September 14, 2026, as stronger-than-expected US inflation data boosted expectations for an imminent Federal Reserve rate hike, according to Shanghai Metals Market (SMM) analysis. The most-traded SHFE tin contract fell sharply, hitting an intraday low of 398,920 yuan/mt and closing the morning session at 400,490 yuan/mt, down 13,330 yuan/mt or 3.22% from the previous trading day. This represented a breach below the psychologically important 400,000 yuan/mt mark.
Meanwhile, SMM number one tin spot prices were quoted at 401,000-404,200 yuan/mt, with an average price of 402,600 yuan/mt, down 8,000 yuan/mt from the previous day. On the London Metal Exchange, LME tin 3M edged lower to $53,100/mt, down $100/mt or 0.19%. The primary driver of the selloff was US August consumer price inflation data released on September 14.
The US August CPI rose 3.4% year-over-year in line with expectations, but the month-over-month increase of 0.4% was the highest since June. Core CPI rose 0.3% on a monthly basis, exceeding market expectations of 0.2%. Following the data release, market-implied probability of a 25 basis point rate hike at the September 15-16 US Federal Reserve meeting rose to approximately 90%, according to market participants.
The 10-year Treasury yield reached 4.986% intraday, approaching the 5% mark, while the US dollar index remained firm and risk assets came under pressure broadly, with nonferrous metals including tin facing headwinds. On the spot market, activity remained brisk despite the price decline. After prices broke below the 400,000 yuan mark, downstream buyers and traders actively restocked, though some clients remained cautious and on the sidelines, watching for further potential price declines.
End-user demand showed early signs of recovery, but order growth remained limited. Downstream demand displayed a clear bifurcation: high-end applications such as AI servers, advanced packaging, and semiconductor-grade tin materials maintained stable demand from a relatively fixed partner base with steady demand release, providing limited incremental supply to the market. In contrast, traditional applications including ordinary solder, tinplate, and tin chemicals were affected by end-use consumption trends, with demand release significantly limited compared to previous years, perpetuating an "underperform in peak season" pattern.
On the supply side, fundamental considerations remained mixed. Although the rainy season has ended in Myanmar's mining areas, water levels and ore grade issues continue to constrain the pace of mining resumption, with China's tin concentrate imports from Myanmar requiring ongoing monitoring. On the Indonesian side, according to Indonesia Exchange data, July and August tin ingot exports were revised to 4,795 mt and 4,510 mt respectively, exceeding 4,500 mt for two consecutive months.
This represented a notable upward revision from earlier market expectations and prompted market reassessment of the probability that Indonesia will meet its full-year production target, though the specific pace still requires confirmation from official data from Indonesia's statistics bureau. Looking ahead, SMM analysts expect the most-traded SHFE tin contract to consolidate on a subdued note in the 395,000-408,000 yuan/mt range in the near term. On the downside, rigid demand support is anticipated near 395,000-400,000 yuan/mt.
A directional breakout will require guidance from the US Federal Reserve meeting decision scheduled for September 15-16, including the dot plot and chair's press conference, as well as further impact from Indonesia's August export data from the statistics bureau on supply-side expectations.
