供需端双增，铅价高位震荡

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Views of the Report - The market's optimistic sentiment has cooled as the positive impact of the Fed's rate cut has materialized. The fundamentals are expected to show a situation of both supply and demand increasing. Primary lead smelters will resume production in the second half of the month, and some secondary lead smelters will resume production due to profit recovery, leading to an expected increase in supply. At the same time, the pre - holiday stocking demand of downstream enterprises has improved, and purchases have increased. With multiple factors at play, it is expected that lead prices will remain volatile at high levels in the short term, and there may be a slight adjustment after the downstream stocking ends [3][7] Group 3: Summary by Directory Transaction Data - From September 12th to September 19th, the SHFE lead price rose from 17,040 yuan/ton to 17,150 yuan/ton, an increase of 110 yuan/ton; the LME lead price fell from 2,019 dollars/ton to 2,003 dollars/ton, a decrease of 16 dollars/ton; the Shanghai - London ratio increased from 8.44 to 8.56, an increase of 0.12; the SHFE inventory decreased by 9,229 tons to 57,332 tons; the LME inventory decreased by 9,275 tons to 220,300 tons; the social inventory increased by 0.35 million tons to 3.94 million tons; the spot premium increased by 10 yuan/ton to - 115 yuan/ton [4] Market Review - Last week, the main contract of SHFE lead switched to PB2511, and the futures price fluctuated narrowly at a high level, closing at 17,180 yuan/ton, a weekly increase of 0.76%.
