铅周报：资金离场持仓下行，沪铅重回运行中枢-20251129

Report Investment Rating - No investment rating for the industry is provided in the report. Core Viewpoint - From the perspective of industrial data, the visible inventory of lead ore has increased, but the smelting start - up rate of primary lead has declined, while that of secondary lead has continued to rise. The weekly start - up rate of downstream battery enterprises has increased marginally, and the visible inventory of domestic lead ingots has decreased marginally. In terms of funds, after two consecutive weeks of decline, the lead price has returned to the oscillation center of 17,000 yuan. Considering the Fed's interest - rate cut cycle, the sentiment in the non - ferrous metals industry is relatively positive, and the short - term lead price is expected to be strong [11].

Although new energy vehicles are gradually replacing lead - acid start - up batteries, the high stock of existing vehicles still provides support for lead consumption. In the base station sector, the increasing number of communication base stations and 5G base stations driven by the development of communication technology has led to a steady increase in the demand for lead - acid batteries [49][51][54]. 5.
