[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.

[Silicon Metal Price Center Remained in the Doldrums]: This week, the silicon metal market stayed weak, with the transaction center for some silicon metal grades edging lower. As of April 2, SMM east China prices were oxygen-blown #553 silicon at 9,000-9,200 yuan/mt, down 100 yuan/mt WoW; 441# silicon at 9,300-9,400 yuan/mt, down 50 yuan/mt WoW; and 3303# silicon at 10,100-10,300 yuan/mt, down 100 yuan/mt WoW. In the futures market, the most-traded silicon metal contract remained weak, with the SI2605 contract closing at 8,300 yuan/mt on Thursday, down 435 yuan/mt WoW. Spot declines were narrower than futures prices, and the advantage in supplier shipments shifted from silicon enterprises to trading firms engaging in both spot and futures market. During the week, market prices were under pressure, while procurement volume from some downstream users and export traders increased, with transactions in some grades remaining moderate.

According to SMM data, total aluminum production outside China in March 2026 edged up 0.2% YoY, while daily average production outside China fell 2.7% MoM, mainly due to extensive production cuts and suspensions at aluminum plants in Mozambique and the Middle East during March. Looking ahead to April, although aluminum plants in the US and Iceland are expected to resume production, the resumption of production at a Spanish aluminum plant continues to advance, and operating capacity at new projects in Indonesia and Angola continues to ramp up, given the large-scale production cuts and suspensions at aluminum plants in the Middle East and Mozambique in March and the further emergence of their impact, aluminum production outside China is expecte

SMM News, March 31， In Q1 2026, amid macro tailwinds, expectations of a supply gap, and successive geopolitical conflicts in the Middle East, aluminum prices repeatedly hit new highs. The quarterly average SMM A00 aluminum price reached 24,028 yuan/mt, up 17.5% YoY; the quarterly average closing price of the LME aluminum 3M contract at 15:00 Beijing time reached $3,196/mt, up 21.8% YoY. High prices suppressed downstream consumption: At the end of 2025, SMM expected China’s primary aluminum consumption growth in 2026 to be 2.0%; as of February, that growth rate had fallen to 1.1%. As a result, the proportion of liquid aluminum in the aluminum industry declined significantly, and aluminum social inventory hit a nearly three-year high. As of March 31, the inflection point in China’s aluminum social inventory was still unclear, while the absolute inventory level had already entered the upper range of SMM’s previous forecast of 1.35-1.4 million mt. However, affected by geopolitical conflicts in the Middle East, aluminum supply and demand were both weak, fundamental risks increased, and prices saw wild swings. Under the impact of high prices, aluminum ingot inventory may continue to build further. According to SMM, as of the end of March, some aluminum ingots in certain regions were still backlogged at rail platforms and outside warehouses. High prices also accelerated supply growth: As of the end of Q1, average profits in China’s aluminum industry exceeded 8,000 yuan/mt. Stimulated by high profits, China’s aluminum supply growth is expected to exceed expectations. At the end of 2025, SMM expected China’s aluminum supply growth in 2026 to reach 1.7%; as of the end of Q1 2026, SMM expected that growth rate had risen to 1.9%. Outside China, supply growth was also boosted by high prices: 1) A smelter in Spain had originally planned to resume full production by 2026, and according to foreign media reports in March, it had already resumed to 90% of operating load; 2) In October 2025, an Icelandic smelter cut production on one line due to equipment failure. It had originally planned to resume production in September-October 2026, but has now moved the plan forward to start by the end of April; 3) At the end of 2025, expectations were that Indonesia’s operating aluminum capacity would reach 2 million mt by the end of 2026; that expectation has now been raised to 2.2-2.5 million mt. Q2 Outlook: At present, one of the decisive factors for global aluminum fundamentals and price trends is the geopolitical situation in the Middle East. SMM analysis showed that outside China, aluminum capacity that had already cut production or faced substantial production reduction risk exceeded 3 million mt. If subsequent production cuts from this portion of capacity are confirmed, outside China aluminum supply is expected to maintain negative YoY growth for an extended period, and global aluminum fundamentals are expected to face a large gap, with the gap outside China far exceeding that in China. In this case, aluminum prices in and outside China are expected to rise sharply again, with overseas prices expected to outperform domestic prices. China’s net aluminum imports are expected to decline, while exports from downstream aluminum plants are expected to increase. However, if actual production cuts come in below expectations, while consumption sees a marked reduction due to factors such as energy and inflation, the upward move in aluminum prices may face insufficient momentum. At present, geopolitical conflicts in the Middle East are disrupting the global aluminum supply-demand pattern, and SMM will continue to follow related developments.

I. Review of SHFE Aluminum Price Trends in Q1 2026 (by Stage) January: The market’s core trading logic deviated from fundamentals and centered on macro expectations for US Fed interest rate cuts Fundamentals: Chinese New Year off-season + demand vacuum + inventory buildup Aluminum prices continued to climb and hit a record high for the period, while downstream profit margins came under pressure, leading to weaker demand for primary aluminum. Repeated environmental protection-driven production restrictions in some regions constrained demand for raw materials. Aluminum social inventory continued to accumulate. As of end-January, SMM aluminum ingot social inventory rose to 782,000 mt, a high for the same period in the past three years. Macro front: In January, the US Fed was in an interest rate cut cycle, and the US dollar weakened significantly. Large amounts of capital flowed into the commodities futures market, driving broad commodity prices higher; together with favorable support from China’s consumption stimulus policies, this jointly supported aluminum prices. February: The market’s core trading logic deviated from fundamentals and centered on macro expectations for the US Fed to keep interest rates unchanged Fundamentals: Aluminum prices were generally in the doldrums. Affected by the Chinese New Year holiday, procurement demand from China’s downstream processing enterprises dropped sharply, aluminum plants showed stronger willingness to cast ingots, and aluminum social inventory continued to accumulate. After the Chinese New Year holiday, SMM aluminum ingot social inventory rose to 1.108 million mt. Elevated inventory levels struggled to provide effective upward support for aluminum prices. Macro front: Cooling expectations for US Fed interest rate cuts pushed the US dollar index higher, and profit-taking outflows triggered a pullback in aluminum prices, further reinforcing their weak and rangebound trend. March: The market’s core trading logic repeatedly switched between supply-side disruptions in the Middle East and demand-side suppression. The tug-of-war between longs and shorts intensified, dominating aluminum prices in a volatile pattern of “surge - correction - rebound.” Supply side: I. Production cut events occurred frequently on the overseas supply side, and disruptions continued to intensify. Mozal entered maintenance status. Qatar Aluminium Smelter announced its decision to stop further production cuts and maintain a 60% operating rate. Aluminium Bahrain initiated shutdowns of Production Lines 1, 2, and 3 under controlled and safe conditions, and the market later heard that Line 4 might also face production cuts or suspension. EGA’s aluminum plant facilities suffered severe damage, and the extent of the damage was still under assessment. The market expected it to undergo large-scale production cuts or suspensions. Ongoing concerns over continued tightening on the overseas supply side became the core driver pushing aluminum prices higher in stages. II. As the Middle East conflict continued to escalate, shipping security in the Strait of Hormuz drew widespread market attention, further increasing uncertainty over global aluminum supply and continuously injecting a geopolitical risk premium into aluminum prices, supporting prices fluctuating at highs. Demand Side: 1. From a macro perspective, concerns over stagflation continued to intensify, risk-off market sentiment picked up, dragging aluminum prices into a pullback and limiting upside room. 2. Hidden concerns on the demand side outside China became more prominent. Some downstream processing enterprises were constrained by multiple factors, triggering market concerns over weak demand: 1) high aluminum prices significantly suppressed downstream purchase willingness, hindering demand release; 2) shortages of energy resources such as natural gas and oil put some processing enterprises under pressure to reduce or suspend production; 3) costs such as freight rates rose sharply, and together with higher smelting costs, further squeezed the profit margins of downstream enterprises, indirectly suppressing demand release.

PT Inalum, Indonesia's state-owned aluminum giant, called on the government to suspend the construction of new alumina and aluminum plants on Tuesday, citing concerns about oversupply and pressure on the country's bauxite reserves. Melati Sarnita, CEO of Inalum, pointed out that Inalum is concerned that the aluminum industry will face similar problems to the nickel industry after rapid growth, such as oversupply affecting global prices and environmental issues. Inalum cited market data to estimate that once all the alumina projects under construction start operating, Indonesia's alumina capacity will increase from the current about 9 million tons to 29.8 million tons. Melati said that once all projects are completed, the original aluminum capacity is expected to increase from the current
