Tin Breaks Below $50,000 for the First Time Since June as Chip Selloff Rocks the Complex

Tin has become the weakest link in the base metals complex this week. LME three-month tin settled at $50,215 a tonne on October 14, down $1,185 or 2.31% on the day, after closing at $51,400 on October 13 (-2.87%) and $52,920 on October 12, according to Xinhua Finance's daily LME wrap. On October 15 the contract broke below $50,000 a tonne for the first time since June, Cailianshe reported. The slide in China has been steeper in local terms: the domestic tin series carried on Market Pulse Scope fell 10.02% over seven days to CNY 373,650 a tonne, while the most-active SHFE contract was quoted at 378,380 yuan a tonne in Mysteel's October 16 morning read.

The proximate cause is macro rather than physical. US producer prices and retail sales both came in above expectations, energy prices pushed inflation pressure higher, and the dollar index swung around the 102 mark before long-dated Treasury yields dropped back. MINING.COM reported that South Korea's Kospi fell almost 8% on October 15, dropping into a bear market as investors questioned how long the AI spending boom can last, and that the memory-chip selloff that began earlier in the week spread across Asian technology stocks. Xinhua Finance noted that the chip-stock volatility directly hit demand expectations for copper and tin, the two metals most leveraged to computing hardware.

Supply-side support has not disappeared, which is why the drop looks like a valuation washout rather than a fundamental reversal. SMM's tin morning summary put LME tin inventory at 4,310 tonnes, down 15 tonnes on the week and at a five-year low, with SHFE warrants at 4,326 tonnes. Myanmar's Wa State restart is running below expectations at roughly 40-50% of capacity because of the rainy season and explosives controls, a large Yunnan smelter is in extended maintenance, and Customs data show Indonesia shipped 3,835 tonnes of tin ingot through the exchange in September with only 1,140 tonnes in the first half of October. SMM expects October domestic refined tin output to fall materially month on month as smelters enter annual maintenance.

Demand is the soft leg. Traders described thin post-holiday restocking, with most buyers covering only immediate needs after a heavy round of replenishment earlier in the week, and the traditional 'silver October' pickup still unproven. Alphamin reported third-quarter tin-in-concentrate output of 5,030 tonnes at an average realised price of $54,374 a tonne against all-in sustaining costs of $20,642 a tonne, showing how far prices would have to fall before primary supply is genuinely threatened. Chinese research houses now frame the market as a wide, weak range with SHFE tin between 380,000 and 405,000 yuan and LME between $49,500 and $54,000 until either electronics orders or Myanmar supply resolves the balance.
