机构：宏观和基本面施压 6月锡价或震荡偏弱

Core Viewpoint - The tin market is experiencing downward pressure on prices due to seasonal demand weakness and the resumption of tin mining in Myanmar, leading to a significant price drop at the end of May [1][2]. Supply Side Analysis - The supply side remains a key focus, with rumors of resumed tin mining in Myanmar's Wa region contributing to price declines. The International Tin Association reported that production in Wa has fully resumed since late April, with the first batch receiving export permits by the end of May [2][3]. - China's tin concentrate imports hit a near-record low in April, with the Democratic Republic of Congo surpassing Myanmar as the largest source of imports. The recovery of Myanmar's production is expected to take time to reach historical capacity levels [2][3]. - As of the end of May, processing fees for tin concentrate in Yunnan and Jiangxi have dropped to their lowest levels in five years, indicating tightening supply affecting smelting profits. The overall refined tin supply may tighten due to reduced imports and ongoing inventory consumption [2][3]. Demand Side Analysis - Despite some resilience in demand, the overall performance is mixed. The photovoltaic sector shows growth, while the semiconductor industry has seen production increases but faces weakening in end-product demand [3][4]. - The PVC sector is operating at high rates but is experiencing significant losses, and the real estate market remains sluggish, impacting demand for PVC and related products [3][4]. - Domestic tin social inventory continues to decline and is at historically low levels, with increased replenishment willingness observed as prices drop significantly [3][4]. Market Outlook - The outlook for June indicates that while short-term price stabilization may occur, uncertainties regarding tariffs and the anticipated recovery in supply, coupled with marginal demand declines, will likely exert downward pressure on tin prices [2][4].
