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

Recently, China’s manganese-based battery materials market has shown an overall pattern of cost-driven dynamics, product differentiation, and gradually recovering demand.

SMM News on March 31: According to SMM statistics, China’s aluminum production in March 2026 (31 days) was up 1.6% YoY and up 10.7% MoM. This was mainly driven by the recovery in calendar days and the gradual resumption of production by downstream enterprises after the Chinese New Year. Operating rates across downstream industries moved higher overall, and the proportion of liquid aluminum rebounded in tandem, up about 9.3 percentage points MoM to 73.7%, exceeding expectations at the beginning of the month. The main reason was that some aluminum plants saw considerable liquid aluminum sales, while sentiment toward casting ingot was weaker than expected at the beginning of the month. Based on SMM data on the proportion of liquid aluminum, China’s aluminum casting ingot volume in March was up 5.3% YoY and down 18.1% MoM. Capacity changes: As of month-end March, SMM statistics showed that China’s existing aluminum capacity was about 46.209 million mt, with no MoM change. Production forecast: Entering April 2026, as the peak season deepens, downstream enterprises are expected to see gradually stronger demand for primary aluminum. The proportion of liquid aluminum is expected to edge higher. Overall, the proportion of liquid aluminum is expected to rise 1.8 percentage points to 75.5%.

[SMM Daily Brief Review of Coking Coal and Coke] In terms of supply, coking coal costs charged into coke ovens at coking enterprises remained high. Coupled with solid demand for coke from steel mills and increased procurement volumes, coke inventory at coking enterprises continued to decline. On the demand side, blast furnace production resumptions at steel mills continued to advance, and hot metal production kept rebounding, strengthening rigid demand for coke. In summary, the supply-demand structure of coke remained tight. In the short term, the coke market may continue to hold up well, and the first round of coke price increases is expected to be implemented soon.

SMM News, March 31: According to SMM statistics, total aluminum production outside China in March 2026 edged up 0.2% YoY, while daily average production fell 2.7% MoM, mainly due to widespread production cuts and shutdowns at aluminum plants in Mozambique and the Middle East during March. According to an announcement on Hydro's official website, Qatalum smelter in Qatar initiated an orderly shutdown on March 3, and announced on March 12 that it had decided to stop further production cuts and maintain a 60% operating rate. On March 16, according to South32's official website, Mozal Aluminium (Mozal) was confirmed to have entered maintenance status on March 15, involving 580,000 mt of capacity. On March 15, according to an announcement on Alba's official website, Alba initiated the shutdown of Lines 1, 2, and 3 under controlled and safe conditions, involving capacity equivalent to 19% of its total capacity of 1.623 million mt, or about 310,000 mt; around March 25, the market reported that its Line 4 might also see production cuts or shutdowns, involving 320,000 mt of capacity; on March 28, according to an announcement on Alba's official website, its aluminum plant facilities were hit on March 28, the extent of equipment damage was still being assessed, and it would maintain operational flexibility and employee safety. On March 28, according to EGA's official website, facilities at its Al Taweelah aluminum plant suffered severe damage, with the extent of the damage still under assessment. The market expects large-scale production cuts and shutdowns there, and the plant has aluminum capacity of about 1.55 million mt. Looking ahead to April 2026 , although the Mount Holly aluminum plant in the US and the Grundartangi aluminum plant in Iceland are expected to begin resuming production, production resumptions at Spain's San Ciprián aluminum plant continue to advance, and operating capacity at new aluminum projects in Indonesia and Angola is expected to continue ramping up, given the large scale of production cuts and shutdowns at aluminum plants in the Middle East and Mozambique in March and the further emergence of their impact, aluminum production outside China in April is expected to decline significantly both YoY and MoM. Overall, if the situation in the Middle East proves difficult to ease, monthly aluminum production is expected to shift into sustained negative YoY growth from Q2 to Q4 2026. Continued attention should be paid to subsequent announcements from relevant aluminum plants in the Middle East and trends in global aluminum inventory.

China’s PMI Returned to Expansion Territory in March — Huo Lihui, Chief Statistician of the Service Industry Survey Center of the National Bureau of Statistics, Interprets China’s PMI for March 2026 On March 31, 2026, the Service Industry Survey Center of the National Bureau of Statistics and the China Federation of Logistics and Purchasing released China’s PMI. In this regard, Huo Lihui, Chief Statistician of the Service Survey Center of the National Bureau of Statistics, provided an interpretation. In March, the manufacturing PMI, the non-manufacturing business activity index, and the composite PMI output index all returned to expansion territory, coming in at 50.4%, 50.1%, and 50.5%, respectively, up 1.4, 0.6, and 1.0 percentage points from the previous month, indicating a rebound in the overall economic prosperity level in China. I. The Manufacturing PMI Rose to Expansion Territory In March, as enterprises accelerated the resumption of work and production after the Chinese New Year and market activity increased, the manufacturing PMI came in at 50.4%, returning to expansion territory. (I) Production and demand expanded simultaneously. The production index and the new orders index stood at 51.4% and 51.6%, respectively, up 1.8 and 3.0 percentage points from the previous month, and both rose into expansion territory. Manufacturing enterprises stepped up production activities, and market demand improved markedly. By industry, the production index and new orders index for such industries as agricultural and sideline food processing, non-ferrous metal smelting and rolling processing were both above 55.0%, and production and demand in related enterprises were released relatively quickly; the two indices for such industries as textile and apparel, chemical fibers, and rubber and plastic products remained below the critical point, with relatively weak market activity. Driven by the recovery in production and demand, enterprises’ purchase willingness strengthened, and the purchasing volume index was 50.9%, up 2.7 percentage points from the previous month. (II) The PMI of large, medium-sized, and small enterprises all rebounded. The PMI of large enterprises was 51.6%, up 0.1 percentage points from the previous month, with the prosperity level rising steadily; the PMI of medium-sized and small enterprises was 49.0% and 49.3%, respectively, up 1.5 and 4.5 percentage points from the previous month, with the prosperity level improving significantly. (III) The three key industries expanded relatively quickly. The PMI of high-tech manufacturing was 52.1%, up 0.6 percentage points from the previous month, and remained above the critical point for 14 consecutive months, indicating continued positive development momentum in the industry; the PMI of equipment manufacturing and the consumer goods industry was 51.5% and 50.8%, respectively, up 1.7 and 2.0 percentage points from the previous month, and both rose to expansion territory; the PMI of high energy-consuming industries was 48.9%, up 1.1 percentage points from the previous month, with the prosperity level showing some rebound. (IV) Price indices rebounded significantly. Affected by factors such as the continued rise in prices of some bulk commodities in the recent period and the acceleration of enterprise procurement activities, the purchase price index of major raw materials and the ex-factory price index stood at 63.9% and 55.4%, respectively, up 9.1 and 4.8 percentage points from the previous month, and the overall price level in the manufacturing market rebounded markedly. By industry, the two price indices for such industries as petroleum, coal and other fuel processing, and chemical raw materials and chemical products were both above 70.0%, and the overall level of purchase and sales prices in related industries rose significantly. (5) Market expectations remained stable with a slight increase. The index of expectations for production and business activities was 53.4%, up 0.2 percentage points MoM, indicating that manufacturing enterprises became somewhat more confident about near-term market developments. By industry, the index of expectations for production and business activities in sectors such as special-purpose equipment, automobiles, railway, shipbuilding, aerospace equipment, and other industries remained in a relatively high expansion range above 56.0%, and the related enterprises were more optimistic about future industry development. The survey results also showed that, affected by factors such as the current geopolitical conflicts in the Middle East, prices of related raw materials such as petroleum and chemicals rose sharply. Coupled with higher logistics freight rates, the proportion of enterprises reporting high raw material costs and high logistics costs both increased MoM this month. II. The Non-Manufacturing Business Activity Index Rebounded In March, the non-manufacturing business activity index was 50.1%, up 0.6 percentage points MoM, indicating an improvement in the prosperity level of the non-manufacturing sector. (1) The service sector business activity index rose above the threshold. The service sector business activity index was 50.2%, up 0.5 percentage points MoM. By industry, the business activity indexes for railway transportation, telecommunications, broadcasting, television and satellite transmission services, monetary and financial services, and insurance all remained in a relatively high expansion range above 55.0%, with total business volume growing relatively fast; after Chinese New Year, the business activity indexes for retail, accommodation, catering, and other industries related to residents' travel and consumption fell below the threshold, and market activity weakened somewhat. In terms of market expectations, the service sector business activity expectations index was 54.8%, continuing to remain at a relatively high level, indicating that service sector enterprises remained optimistic about near-term market developments. (2) The construction sector business activity index improved. As construction projects across various regions gradually resumed work after the holiday, the construction sector business activity index was 49.3%, up 1.1 percentage points MoM. In terms of market expectations, the construction sector business activity expectations index was 50.5%, above the threshold, indicating that construction enterprises remained confident about future industry development. III. The Composite PMI Output Index Rose Above the Threshold In March, the composite PMI output index was 50.5%, up 1.0 percentage points MoM, indicating that the overall level of production and business activity across China's enterprises continued to improve. The manufacturing production index and the non-manufacturing business activity index, which together constitute the composite PMI output index, were 51.4% and 50.1%, respectively.
