[SMM Tin Midday Review: Liquidity Expectations Continue to Weigh on Metal Prices, SHFE Tin Contract Center Continues to Decline]

"Tin" Leads the Future: Industrial Transformation and Value Reshaping in a New Cycle **Conference Background** Currently, the global tin industry stands at a historic turning point, where traditional cyclical logic has been fundamentally disrupted and strategic value has become fully prominent. The tin market in 2026 presents an unprecedented complex pattern and profound transformation: **I. Deep Restructuring of the Supply-Demand Pattern with Unprecedented Enhancement of Strategic Attributes** The global static reserve-to-production ratio of tin resources is only 14 years, with scarcity becoming increasingly prominent. The supply side faces "triple pressures": repeated setbacks in Myanmar's production resumptions, continued policy tightening in Indonesia, and elevated geopolitical risks in the DRC — resource constraints have become the new normal. Meanwhile, the demand structure has undergone a fundamental shift, and tin has become a strategic resource connecting traditional manufacturing with the digital future. **II. Price System Breaking Historical Records with the Industrial Ecosystem Facing Reshaping** In early 2026, SHFE tin prices broke through 470,000 yuan/mt, hitting a record high. This price breakthrough is not only a reflection of supply-demand imbalance but also a hallmark of the revaluation of the tin industry. Traditional trade models, risk management systems, and supply chain collaboration approaches all urgently require innovative breakthroughs. **III. Technology-Driven and Green Transformation Giving Rise to a New Symbiotic Ecosystem** Digital and intelligent technologies are deeply empowering the tin industry chain. The global green transformation requires the tin industry to upgrade towards low-carbonisation and circular economy, making recycled tin recovery and green smelting processes an inevitable path. All segments of the industry chain must shift from competition to collaboration, building an open, resilient, and innovative symbiotic system. Against this backdrop, August 19-21, 2026 in Changsha, Hunan , the 2026 SMM (16th) Tin Industry Chain Conference will bring together global industry elites for in-depth discussions.
