有色金属月报(精炼锡):缅甸佤邦锡矿完全复产仍需时间美联储9月降息预期支撑全球锡价-20250901
- Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The Fed's expected rate cut in September and the time needed for the full resumption of tin mines in Wa State, Myanmar, along with weak downstream demand in sectors like home appliances and solders, may cause Shanghai tin prices to weaken first and then strengthen. Investors are advised to buy on price dips, with attention on support and resistance levels [3]. - The negative basis and monthly spread of Shanghai tin are due to weak domestic demand in sectors such as home appliances and solder materials. Given the expected Fed rate cut in September, partial production suspension for maintenance of domestic refined tin capacity, and the decline in domestic refined tin social inventory, investors are recommended to pay attention to short - term, light - position arbitrage opportunities by going long on the Shanghai tin basis at low prices [6]. - The positive spreads of LME tin (0 - 3) and (3 - 15) contracts, along with the Shanghai - London tin price ratio slightly below the 50% quantile of the past five years, are due to the expected Fed rate cut in September and the relatively low inventory of refined tin at the LME. It is suggested to temporarily watch the arbitrage opportunities of LME tin (0 - 3) and (3 - 15) contract spreads [9]. 3. Summary by Related Contents Supply - side - Tin Ore: Namibia's Uis mine's second concentrator started commissioning in late August with a maximum monthly ore - processing capacity of 40,000 tons. In Myanmar's Wa State, the first batch of 40 - 50 mines will resume production after paying fees, with an initial increment of no more than 10,000 metal tons and a 2 - 3 - month transmission period. These factors may lead to a month - on - month increase in domestic tin ore production and a decrease in imports in September [2][20]. - Recycled Tin: China's recycled tin production in September may decrease month - on - month [21][23]. - Refined Tin: The capacity utilization rate of refined tin in Yunnan and Jiangxi has decreased compared to last week. Yunnan Tin will conduct maintenance on smelting equipment from August 30 for no more than 45 days, resulting in a month - on - month decrease in China's refined tin production and an increase in inventory in September. Indonesia's export volume in September may decrease, which may lead to an increase in China's refined tin imports and a decrease in exports [2][27][31]. Demand - side - Tin Solder: China's tin solder capacity utilization rate in September may increase month - on - month, while inventory may decrease [35][37]. - Photovoltaic Welding Tape: China's photovoltaic welding tape imports in September may decrease month - on - month, and exports may increase [39][41]. - Tin - Plated Sheet: China's tin - plated sheet production, imports, and exports in September may all decrease month - on - month [43][45]. - Integrated Circuits and Smartphones: China's integrated circuit and smartphone production in September may increase month - on - month [47][50]. - Lead - Acid Batteries: China's lead - acid battery capacity utilization rate has decreased compared to last week [53][56]. Inventory - The inventory of refined tin in the SHFE has increased compared to last week; China's tin ingot social inventory has decreased; the inventory of refined tin at the LME has increased; the total domestic and foreign refined tin inventory has increased [12]. Price and Spread - China's tin concentrate price has increased compared to last week, and tin concentrate imports are still profitable. The daily processing fee of domestic tin concentrate has decreased, indicating a tight supply expectation [16]. - The basis of Shanghai tin is negative and at a relatively low level, and the monthly spread is negative and basically within a reasonable range [4][6]. - The spread of LME tin (0 - 3) contract is positive and at a relatively high level, and the spread of (3 - 15) contract is positive and basically within a reasonable range. The Shanghai - London tin price ratio is slightly below the 50% quantile of the past five years [7][9].
