Core Viewpoint - Recent fluctuations in tin prices on the Shanghai Futures Exchange have been characterized by significant volatility, with prices rising over 10% in the first quarter and reaching a 34-month high before experiencing a drop of over 20% in just five trading days, driven by macroeconomic shocks and supply-demand mismatches [1][2]. Group 1: Market Dynamics - The sharp decline in tin prices is attributed to two main factors: the U.S. "reciprocal tariff" policy raising concerns about increased global trade costs and demand contraction, and supply expectation adjustments from major producing regions like Myanmar and the Democratic Republic of Congo [2]. - The ongoing trade war and changing tariff policies have led to heightened market risk aversion, significantly impacting tin as a high-volatility commodity [2]. - The tightening of dollar liquidity and geopolitical conflicts have further exacerbated market fluctuations, with LME tin inventories dropping to their lowest point in 2023 [2]. Group 2: Supply and Demand Analysis - Current supply-demand dynamics indicate a "tight but not lacking" supply situation, with demand showing signs of recovery from weakness [6]. - Data shows that China's tin ore imports in January-February 2025 fell nearly 50% year-on-year, with a sharp 81.07% decline in imports from Myanmar, influenced by recent earthquakes affecting supply [6]. - The global mining capital expenditure growth rate for tin-related projects from 2019 to 2024 is only 1.2%, indicating a mismatch between existing project recovery and new project development timelines against demand growth [6]. Group 3: Future Outlook - The demand for tin is expected to significantly improve in the medium to long term, supported by growth in sectors such as semiconductor chips, 5G communications, photovoltaic cells, and AI chip soldering materials [6][8]. - The International Tin Association predicts a "non-linear leap" in tin demand from AI servers, with consumption per server expected to be three times that of traditional devices by 2025 [8]. - Despite the ongoing global trade tensions, tin is recognized as a strategic resource, with its overall value anticipated to rise as macroeconomic concerns are gradually absorbed by the market [8].
