DRC Bisie Tin Mine Halts Production; SHFE Tin Hits Limit-Up in Early Trading [SMM Tin Midday Review]

March 14, 2025 SHFE Tin Futures Most-Traded Contract Midday Commentary On March 14, 2025, the most-traded SHFE tin futures contract hit the daily limit during the morning session, surging by 10% to 291,510 yuan/mt, marking the highest level since May 2022. By midday, the market hovered at highs, with open interest increasing by 10.08% compared to the previous day and net capital inflows exceeding 10 billion yuan, indicating highly active market sentiment. Supply-Side Sudden Impact DRC Bisie Tin Mine Halts Production: Alphamin Resources' Bisie mine, with an annual output of 17,000 mt, has suspended operations due to security concerns, accounting for approximately 6% of global supply, exacerbating expectations of a global tin ore shortage. Market Sentiment and Capital Resonance Inflows of Safe-Haven and Speculative Funds: COMEX gold surpassed $2,200, and tin, as a niche metal, became a focus of speculative trading. After breaking through the key technical resistance level of 280,000 yuan/mt, prices accelerated upward. Short-Term Risks: High prices may suppress downstream purchase willingness, and a pullback in spot premiums could trigger a correction. A rapid easing of the situation in the DRC might alleviate supply concerns. The current SHFE tin market is driven by supply disruption events. In the short term, it may continue to hover at highs, but attention should be paid to the progress of production resumption in the DRC, inventory changes, and macro policy directions. Investors should balance short-term fluctuations with medium and long-term supply-demand imbalances and respond rationally to changes in market sentiment.
