SHANGHAI, Oct. 17 (SMM) – Mainstream traded prices for spot aluminum in south China rose RMB 40/mt to RMB 14,370-14,430/mt on Thursday. Aluminum stocks in the region began to drop as more aluminum ingot has been shipped to east China. This eased oversupply pressure there. Meanwhile, downstream producers purchased as needed, pushing prices up. Offers were reported at RMB 14,370-14,400/mt before noon. As cargo holders began to hold off from selling, quotations rose to RMB 14,400-14,450/mt in the afternoon. However, higher offers watered down buying interest.
