Primary lead: inventory at primary lead smelters continued to decline, while suppliers held firm on quotes and showed a clear reluctance to sell. Secondary lead: as losses widened, most secondary lead enterprises stayed on the sidelines and were reluctant to sell, tightening effective supply in the market overall. Downstream battery plants: after restocking demand was met, the procurement pace slowed down, and downstream demand remained weak. Overall, the market still showed a pattern of weak supply and weak demand. In the short term, lead prices are expected to remain in the doldrums, and close attention should be paid to changes in secondary lead operating rates in late March and shifts in downstream purchasing strength.

[Macro Pressures Combined With High Inventory, SHFE Aluminum Remained Under Pressure at Elevated Levels in the Short Term] Continued destocking in LME inventory provided bottom support for LME aluminum, but amid tightening fund liquidity and profit-taking by bulls, upward momentum was insufficient, and the backwardation structure weakened somewhat. In China, social inventory rose to a high for the same period in nearly five years, and the inventory buildup cycle had not ended. High inventory and weak spot fundamentals jointly weighed on upward momentum. The divergence between domestic and overseas drivers continued, the SHFE/LME price ratio kept weakening, and SHFE aluminum fell below the key threshold of 25,000 yuan/mt, remaining mainly under pressure at elevated levels in the short term.
