[SMM Tin Midday Review: Tin Prices See Roller Coaster Ride Again, Tug-of-War Between Longs and Shorts Leads to High-Level Stalemate] The most-traded SHFE tin contract showed a fluctuating downward trend. By the midday close, SHFE tin prices were clearly under pressure, down more than 1% from the previous day's settlement price. This movement extended the previous trading day's correction, with the most-traded SHFE tin contract closing overnight at 290,940 yuan/mt, down 3,310 points, a decline of 1.12%. From a macro perspective, recent market sentiment fluctuations have intensified significantly, becoming a key factor affecting short-term tin price movements. US Fed officials Logan and Schmid released strong hawkish signals, explicitly opposing a December interest rate cut, which cooled market expectations for a shift in the US Fed's monetary policy. This change boosted the US dollar index, thereby putting pressure on dollar-denominated metal prices. Meanwhile, domestic economic data for October showed mediocre performance, with industrial added value of enterprises above designated size up 4.9% YoY, and demand boost remaining insufficient, making it difficult to provide effective support for tin prices.
