Report Industry Investment Rating - Not provided in the given content Core Viewpoints - The resumption of tin mines in Wa State, Myanmar, and the Democratic Republic of the Congo, along with the increasing operating rate of domestic refined tin production capacity, but the decrease in refined tin inventories both at home and abroad compared to last week, may lead to an adjustment in Shanghai tin prices. It is recommended that investors hold their previous short positions cautiously and pay attention to the support and resistance levels [3]. - The positive basis and negative monthly spread of Shanghai tin, as well as the negative (0 - 3) and positive (3 - 15) contract spreads of LME tin, are within reasonable ranges. Due to various factors, it is suggested to temporarily wait and see for arbitrage opportunities [6][11]. Summary by Related Catalogs Supply Side - On July 11, Wa State, Myanmar, decided that the first batch of 40 - 50 mines would resume production after paying fees (with an initial incremental output of no more than 10,000 metal tons and a transmission period of 2 - 3 months, totaling 108 mines). Alphamin Resources announced the phased resumption of the Bisie tin mine in North Kivu Province, Democratic Republic of the Congo, on April 9 (with production volumes of 17,300 and 20,000 tons in 2024 and 2025 respectively). These factors may cause the domestic tin ore production (import) volume in July to decrease (increase) month - on - month. Coupled with the decline in domestic tin concentrate processing fees, it may indicate a tight supply expectation of domestic tin ore [3][22]. - China's recycled tin production in July may increase month - on - month [23][25]. - The operating rates of refined tin production capacity in Jiangxi and China (Yunnan) increased (remained flat) compared to last week; China's refined tin production (inventory) volume in July increased (decreased) month - on - month [3][29]. - Indonesia's Ministry of Finance's mining license approval is affected by a corruption investigation and may reduce long - term export quotas, causing the export volume in July to decrease month - on - month. China's refined tin import (export) volume in July may increase (decrease) month - on - month [3][33]. Demand Side - The operating rate (inventory) of China's tin solder production capacity in July may increase (increase) month - on - month [3][36]. - China's solder strip import (export) volume in July may increase (increase) month - on - month [3][38][40]. - China's tinplate production (import, export) volume in July may increase (decrease, decrease) month - on - month [3][44]. Inventory - The social inventory of China's refined tin decreased compared to last week. The inventories of refined tin in the Shanghai Futures Exchange, Chinese tin ingot social inventory, and LME refined tin also decreased compared to last week [12][14]. Price and Spread - The basis of Shanghai tin is positive and within a reasonable range, and the monthly spread is negative and within a reasonable range. The (0 - 3) contract spread of LME tin is negative and within a reasonable range, while the (3 - 15) contract spread is positive and within a reasonable range. The Shanghai - London tin price ratio is lower than the 50% quantile of the past five years [6][11]. Investment Strategy - It is recommended that investors hold their previous short positions cautiously and pay attention to the support level around 248,000 - 260,000 and the resistance level around 274,000 - 280,000 for Shanghai tin, and the support level around 30,000 - 32,000 and the resistance level around 34,000 - 36,000 for London tin [3]. - It is suggested to temporarily wait and see for arbitrage opportunities regarding the basis and monthly spread of Shanghai tin, as well as the (0 - 3) and (3 - 15) contract spreads of LME tin [6][11].
