The social inventory is expected to decline, and the macro - situation is favorable [6]. - The alumina price is neutrally treated due to factors such as ore - end disturbances, winter storage expectations, and the Guinea election event. The supply - demand balance is slightly in surplus [7]. - The production profit of aluminum alloy is significantly repaired, indicating actual consumption recovery. Attention can be paid to the spread arbitrage of the 11 - contract [7]. Group 3: Summary by Related Catalogs 1.

Market Analysis Electrolytic Aluminum - The supply side remains unchanged, consumption shows positive signs, and the spot discount is slightly repaired. The downstream processing enterprises' production and operating rates are increasing, showing signs of a transition from the off - season to the peak season. The social inventory accumulation has slowed down, and de - stocking is expected. The macro - situation is favorable, and overseas consumption remains strong [6]. Alumina - In Guangxi, 5,000 tons of alumina were traded at a spot - cash price of 3,180 yuan/ton. The rainy season affects the import of Guinea ore and domestic ore mining.

The alumina price is neutrally treated [6][7]. Aluminum Alloy - The supply of scrap aluminum is tight, but the production profit is significantly repaired, and the price difference between the spot price and aluminum ingots shows a seasonal repair trend, indicating actual consumption recovery. The increase in social inventory is mainly due to the transformation of invisible inventory to visible inventory. Attention can be paid to the spread arbitrage of the AD2511 - AL2511 contract [7]. 3. Strategy Unilateral - Aluminum: Cautiously bullish; Alumina: Neutral; Aluminum alloy: Cautiously bullish [8] Arbitrage - Shanghai aluminum positive spread arbitrage; Long AD11 and short AL11 [8]

Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Core Views - The methanol market has a loose supply situation, with high domestic methanol开工率 and increasing imports.

Core Viewpoint - The rebar steel market is experiencing a downturn due to various negative factors, despite some supportive policies in the real estate sector. The overall market sentiment is shifting, leading to a decline in prices and increasing inventory levels [1][2][3]. Group 1: Price Trends - Since mid-August, rebar futures prices have weakened significantly, with the main contract dropping from 3274 CNY/ton to 3097 CNY/ton, a decline of nearly 5.4% [1]. - Spot prices have also decreased, with mainstream regions in East China seeing declines of 80 to 110 CNY/ton [1]. - As of August 22, the total inventory of rebar reached 6.0704 million tons, an increase of 198,500 tons week-on-week, marking four consecutive weeks of accumulation [1]. Group 2: Production and Supply - The weekly production of rebar is reported at 2.1465 million tons, a decrease of 65,300 tons over two weeks, primarily due to long-process steel mills shifting production to steel billets [2]. - The average capacity utilization rate of 90 independent electric arc furnace steel mills is at 75.69%, indicating limited room for supply contraction [2]. - There are expectations of production restrictions around Beijing, which could boost market sentiment if implemented [2]. Group 3: Demand Indicators - Rebar demand remains weak, with weekly demand recorded at 1.9480 million tons, continuing to be at a low level compared to recent years [2]. - Key indicators such as cement dispatch and concrete delivery have also shown declines of 16.5% and 7.8% year-on-year, respectively, further confirming the sluggish demand in the construction market [2]. Group 4: Market Outlook - Despite the re-emergence of favorable policies in the real estate market, the overall industry remains in a weak recovery phase [3]. - The recent increase in rebar futures arbitrage activity may lead to a profit-taking window, potentially increasing pressure on demand [3]. - The current supply-demand imbalance suggests that steel prices will remain under pressure, although rising costs may limit further declines, with expectations of a fluctuating bottoming-out trend in prices [3].
