Spot Aluminum Prices Struggle to Break Through Supply-Demand Constraints; Trading in South China Aluminum Market Shows Divergence [SMM South China Spot Aluminum Daily Review]

Published: Dec 17, 2025 19:34 (GMT+8)

SMM December 17:

For aluminum ingots in South China, the average SMM A00 aluminum (Foshan) price on December 17 was 21,640 yuan/mt, up 120 yuan/mt on the day, at a discount of 215 yuan/mt against the front-month contract, widening by 5 yuan/mt from the previous day. A sharp decline in social inventory today supported suppliers to hold prices firm. However, driven by the core year-end need for destocking and cash flow, market willingness to sell remained strong, keeping circulation loose. Morning offers were mainly concentrated at -10 to 0 yuan/mt. Downstream rush to buy amid continuous price rise provided a floor, but the incomplete implementation of new long-term contracts dampened traders' purchase willingness, leading to weak initial transactions. Later, continued futures gains pushed offers to around +100 yuan/mt, prompting some buyers to replenish low-priced cargo, marginally improving transactions.

For aluminum billets in South China, on December 17, the processing fees for various specifications of SMM 6063 aluminum billets (Guangdong) were stable to lower. The average fee for Φ90/100 was 450 yuan/mt, while for Φ120 and above it was 400 yuan/mt, flat from the previous day , with price differences persisting in market quotes. A significant rise in the base price failed to spur downstream rush to buy amid continuous price rise. Enterprises prioritized securing low-priced cargo, resulting in limited overall demand. Subsequent offers were gradually lowered, leading to mixed transaction performance throughout the day, with processing fees lacking upward momentum.

Inventory side, on Wednesday, aluminum ingot and billet inventories in major consumption areas decreased by 10,500 mt and 2,000 mt WoW, respectively, with South China seeing destocking of 2,000 mt and 1,000 mt. Short term, the pullback in absolute prices supports sellers' willingness to hold prices firm, but weakening demand reduces downstream purchase willingness, and spot discounts are expected to fluctuate.

Yantai Port Breaks Global Bauxite Discharge Record with Arrival of Winning Ambition Vessel
On September 19, the Winning Ambition, carrying 320,000 mt of Guinean bauxite, successfully berthed at Berth 502# in the West Port Area of Yantai Port, Shandong Port Group, to begin discharge operations, marking the fourth time Yantai Port has refreshed the global record for the largest single-vessel bauxite discharge volume. The Winning Ambition is the first vessel in Winning International's WINNINGMAX Sirius series, built by CSSC Qingdao Beihai Shipbuilding. The vessel is equipped with an integrated hull methanol fuel tank, has received DNV methanol-ready certification, and its EEDI is 33.9% lower than the baseline. As a green VLOC giant designed for future zero-carbon shipping, it undertakes long-haul ocean transport of Simandou iron ore and Guinean bauxite, connecting overseas resource supply sources with port logistics hubs and setting a model for building an efficient, low-carbon, and secure global mineral supply chain. This first call once again demonstrates Shandong Port Group's resolve to accelerate the development of a bulk dry cargo storage, transfer, and distribution hub, as well as its strong capability in handling ultra-large vessels. To date, Yantai Port has received a cumulative total of 82 bauxite vessels of the 300,000 mt class, marking the sustained and stable operation of the China-Africa ultra-large ore carrier bauxite transport project. This further consolidates Yantai Port's advantage as the leading port for China-Africa trade and injects strong momentum into accelerating the development of a key hub in the domestic and international dual circulation and advancing high-quality Belt and Road cooperation.
