[Worsening Supply Concerns and Gradual Demand Recovery Stabilize the Center of Aluminum Prices with Geopolitical Premiums ]Overall, the market's core focus in the period ahead is on whether key aluminum smelters in the Middle East will further expand production cuts. If the cuts continue to materialize, they will provide strong upward momentum for global aluminum prices, coupled with support from expectations of a gradual release of demand during China’s peak season. In the short term, aluminum prices are expected to remain in a high-level consolidation pattern.

[SMM Cast Aluminum Alloy Morning Comment: Slightly Pessimistic Demand Expectations Cap Upside Room for ADC12 Prices]: On Thursday, ADC12 market prices remained largely stable. Downstream procurement is currently staying cautious, and overall market transactions were mediocre. Some enterprises are pessimistic about April order expectations, with wait-and-see sentiment intensifying and demand continuing to provide weak support for prices. The market’s primary contradiction has shifted from raw material cost-driven factors to insufficient consumption momentum. The increase in finished alloy ingot prices has clearly lagged behind the raw material side, and industry profit margins have consequently narrowed.

[SMM Aluminum Express News] Vedanta Aluminium is advancing a major expansion in Odisha with a planned investment of around ₹1.8 lakh crore (~US$21–22 billion), reinforcing its strategy to scale up an integrated aluminum value chain. The project includes a 3 MTPA aluminum smelter, 6 MTPA alumina refinery, and a 4,900 MW captive power plant, alongside downstream facilities—strengthening its position as a fully integrated producer.

[SMM Aluminum Express News] PT Bukit Asam (PTBA) is seeking partners to build a 1.25 GW coal-fired power plant in Mempawah to support Inalum’s 600,000 tpy aluminum smelter. The project, backed by an MoU between PTBA and Inalum, will require ~5.5 million tons of coal annually (180–200 million tons over 30 years). PTBA targets FID by end-2026, with potential project start in 2027. The smelter itself is part of a larger integrated bauxite–alumina–aluminum chain, with US$2.4 billion investment for the smelter and US$890 million for SGAR Phase 2. It will process 3 Mt bauxite into 1 Mt alumina, then into 600 kt aluminum, supplied by Antam mines. Overall, this strengthens Indonesia’s downstream strategy, boosting domestic alumina capacity to 2 Mt/year and bauxite absorption to 6 Mt/year.

The current global aluminum market showed a clear divergence between markets outside and inside China. LME remained strong amid supply-side disruptions, while the Chinese market also strengthened under supply disruptions, though its overall performance was still relatively weaker than LME. Details on supply and demand, trade flows, and market structure are as follows: I. Overseas Aluminum Market: Tight Supply Became More Pronounced, Inventory Remained Under Pressure The core issue in the overseas aluminum market centered on supply contraction and low inventory, compounded by disruptions from geopolitical conflicts, with the tight supply pattern continuing to intensify. Based on LME inventory data, current inventory remained on a sustained downward trend, and the support provided by inventory to the market weakened significantly. Historical and recent data showed that LME cancelled warrants previously peaked at 178,000 mt, accounting for as much as 39 of total inventory. As a result, LME's actually available effective inventory fell to the lowest level since May 2025, further highlighting the tight supply situation outside China. The contraction on the supply side further amplified the deficit in markets outside China, with the impact of production cuts at the two key projects, EGA and Alba, being particularly prominent. On March 28, EGA's Al Taweelah production site in the UAE and Alba's plant in Bahrain were both attacked, and equipment damage sharply increased the risk of capacity disruptions. In addition, Alba had already started production cuts on three lines on March 15 due to shipping disruptions in the Strait of Hormuz, while Qatar's Qatalum aluminum smelter shut 40 of its capacity on March 12 due to a natural gas supply interruption. Against this backdrop, the supply gap in overseas aluminum ingot is expected to continue widening. Meanwhile, high energy costs in Europe also led to production cuts and volume reductions in local fabricated products, further exacerbating supply tightness. Tight supply directly pushed premiums in overseas spot markets sharply higher. Affected by supply concerns triggered by the escalation of geopolitical conflict in the Middle East, the Q2 MJP price rose by about $156.5/mt to $351.5/mt. Specifically, by month-end, premiums in major regions all showed a significant upward trend: CIF South Korea premiums rose from $168/mt at the beginning of the month to $292/mt; CIF Thailand premiums rose from $183/mt to $317/mt; Europe duty-unpaid premiums rose from $345/mt to $400/mt; and US Midwest DDP premiums rose from 103.75¢/lb at the beginning of the month to 105.5¢/lb, fully reflecting that current expectations of tight overseas aluminum ingot supply pushed sellers to raise offers. From the perspective of downstream demand and procurement pace across overseas regions, clear divergence was evident: South Korea: phased restocking had already been completed earlier, and downstream purchase and restocking sentiment was currently weak, with demand providing limited support to the market; Southeast Asia: the market was currently focused on digesting inventories, with only partial spot order restocking demand, and overall momentum for new purchases was insufficient; Europe: affected by production cuts in Qatar and Bahrain's aluminum industries, market concerns over a supply deficit continued to intensify, and downstream players were gradually carrying out restocking purchases, with demand showing relatively strong performance; US: inventory was currently at a low level and was entering a restocking cycle, providing some support to the market. II. China’s Aluminum Market: Under Pressure from Inventory at High Levels, with Suppressed and Weak Demand In contrast to the strength of the LME, although China’s aluminum market was likewise supported by supply disruptions and showed an upward trend, its overall performance remained relatively weaker than the LME, with the core pattern characterized by “elevated inventory and suppressed demand.” On the price front, persistently high aluminum prices in China continued to restrain downstream purchasing demand. At present, the downstream procurement pace is mainly driven by order-based just-in-time procurement, while willingness to restock proactively remains subdued, making it difficult to form stronger demand support. China has not effectively eased inventory pressure—domestic aluminum ingot remains at inventory at high levels, and the pace of inventory drawdown was slower than expectations. Inventory drawdown is expected to take even longer going forward. Inventory at high levels and high aluminum prices have formed a dual constraint, leaving the Chinese market with upward momentum, but weaker than that of the LME. In the short term, spot premiums in China are expected to remain under pressure and widen further. Source: SMM

[Supply Tightening Coupled With Macro Tailwinds Keeps Aluminum Prices Firmly at High Levels] Overall, the geopolitical situation in the Middle East remains the core factor affecting the global aluminum market. A series of production cuts and damage incidents at Middle Eastern aluminum plants is expected to provide strong upward momentum for aluminum prices in and outside China, together with support from expectations of gradually releasing peak-season demand in China. In the short term, aluminum prices are expected to remain in a high-level consolidation pattern.
