算力金属锡突发异动，半个月暴涨4万元/吨！月内大涨超11%

Core Viewpoint - The recent surge in tin prices, driven by supply constraints and geopolitical factors, has raised concerns within the industry regarding the impact on downstream companies and overall market stability [1][11]. Group 1: Price Trends and Market Dynamics - Tin prices have reached new highs, with LME tin increasing by 11.5% and SHFE tin by over 13% since December 2025, with a notable rise of over 40,000 yuan per ton in just half a month [1][5]. - The LME tin futures contract and SHFE tin main contract have both seen significant price increases, with the highest prices breaking through $43,900 per ton and 349,000 yuan per ton, respectively [5]. - The recent price movements have prompted the Tin Industry Association to issue a statement highlighting the irrational price increases and their disruptive effects on the supply chain [11]. Group 2: Supply and Demand Analysis - Supply from major producing countries like the Democratic Republic of Congo and Myanmar is stabilizing, with exports from Wa State reaching nearly 1,000 tons per month, and domestic smelting capacity utilization is high, with refined tin production reaching 189,000 tons, a 6.2% year-on-year increase [7]. - Despite growth in emerging sectors like photovoltaics and automotive electronics, traditional demand remains stable, with global tin consumption expected to grow by nearly 3% in 2025, slightly below production growth [7]. - The current global tin supply-demand balance shows a surplus of about 10,000 tons, indicating that the recent price increases are more driven by market sentiment and speculation rather than fundamental supply-demand changes [7][9]. Group 3: Impact on Downstream Industries - Downstream industries, particularly small and medium-sized enterprises in sectors like solder, tinplate, and chemicals, are facing significant cost pressures due to rising tin prices, leading to challenges in fulfilling long-term contracts and maintaining product quality [3][11]. - The electronics manufacturing sector, a major consumer of tin-based solder, is experiencing acute cost increases, which are eroding profit margins [12]. - The Tin Industry Association, along with the China Electronic Industry Association, has called for a rational and cautious approach to pricing, urging all market participants to avoid blind speculation and work towards stabilizing prices [12].
