Inventory: According to SMM statistics, as of August 20, the combined daily social inventory of secondary aluminum alloy ingots in Foshan, Ningbo, and Wuxi totaled 31,596 mt, up 164 mt from the previous trading day but down 16 mt from Wednesday last week (August 13).
Summary: Aluminum prices pulled back slightly yesterday, while the SMM ADC12 price held steady at 20,350 yuan/mt. Currently, aluminum scrap supply remains tight, leading to a slower decline in aluminum scrap prices, and high raw material costs continue to support secondary aluminum alloy prices. In addition, recent news of tax rebate cancellations in multiple regions of Anhui and Jiangxi has prompted companies to maintain firm offers in response to rising cost pressures. Demand side, the traditional off-season sentiment persists, with sluggish improvement in actual consumption and mediocre transaction performance. In the short term, cost support and policy disruptions may continue to underpin prices, but weak demand coupled with inventory buildup pressure will limit upside room. Going forward, close attention should be paid to the implementation of policies and the recovery pace of demand in the peak season.
