SHANGHAI, Dec. 21 (SMM) – The most active SHFE aluminum contract prices rose to test RMB 15,800/mt on Wednesday. Since aluminum inventories in spot market in South China were still relatively low, cargo holders’ selling interest remained low, pushing aluminum prices to rise above RMB 16,000/mt. Main transactions were done at RMB 16,030-16,050/mt. Downstream buyers purchased on as-needed basis with heavier financial pressure. Limited transactions were done on Wednesday.
