Report Summary 1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints - This week, the spot price of domestic butadiene rubber in the market dropped from a high level. Due to strong demand for raw material butadiene and unexpected shutdown of some plants, the production cost of butadiene rubber has increased significantly. Although most private butadiene rubber plants in North China have reduced their production to varying degrees, the weak downstream demand has led to increased inventory in production enterprises and sample trading enterprises. It is expected that the inventory of trading enterprises will decline in the short term. The capacity utilization rate of domestic tire enterprises has continued to increase this week, but the production schedule of some enterprises has been slightly adjusted, and a few enterprises have maintenance plans at the end of the month, which may affect the overall capacity utilization rate. The br2507 contract is expected to fluctuate in the range of 11,500 - 12,000 in the short term [7]. 3.

Group 2: Glass and Soda Ash Industry Report Industry Investment Rating No information provided. Core View - **Soda Ash**: The supply of soda ash has new pressure with the output of Lianyungang Alkali Industry. Although the production decreased significantly due to maintenance last week and the market has a strong expectation of maintenance from May to June, the inventory is expected to remain flat in the short term. In the medium - to - long term, there is still pressure for further inventory accumulation after the maintenance. From May to June, the implementation of maintenance can be tracked. If the maintenance is implemented, it will be beneficial to the June - July contracts. For single - side trading, short - term high - selling operations on the far - month contracts are recommended, and for inter - month trading, a long - July and short - September strategy can be considered [3]. - **Glass**: The spot market of glass is generally weak, and the market sentiment is still pessimistic. The spot price of glass has further declined recently. Although the downstream deep - processing orders have gradually improved from April to May and the demand of processing plants has seasonally recovered, the market expectation is poor, and there is an expectation of a summer rainy - season off - peak from June. The actual fundamentals have marginally improved, but the expectation and sentiment are moderately weak. It is expected that the glass price will continue to be under pressure and fluctuate weakly in the short term. It is necessary to observe whether the 1000 level can provide support for the 09 contract [3]. Summary by Directory - **Glass - related Prices and Spreads**: On May 22, the North China quotation remained unchanged at 1,180 yuan/ton, the East China quotation decreased by 10 yuan/ton to 1,310 yuan/ton, a decline of 0.76%, the Central China quotation remained unchanged at 1,130 yuan/ton, and the South China quotation remained unchanged at 1,320 yuan/ton.

Group 3: Industrial Silicon Industry Report Industry Investment Rating No information provided. Core View The spot price of industrial silicon in East China continued to decline by 100 yuan/ton, and the futures price continued to be under pressure and declined. The price has been continuously falling mainly because, even at low prices, the supply is still expected to increase while the demand remains weak. The fundamentals have not shown signs of improvement, and the price may continue to be under pressure. The price fluctuation range is adjusted down to 7,500 - 9,500 yuan/ton. If the price continues to fall, attention can be paid to the capacity clearance [4]. Summary by Directory - **Spot Prices and Basis of the Main Contract**: On May 21, the price of oxygen - passing SI5530 industrial silicon in East China decreased by 100 yuan/ton to 8,700 yuan/ton, a decline of 1.14%.

The 2507 - 2508 spread increased by 5 yuan/ton to - 25 yuan/ton, a rise of 16.67%. The 2508 - 2509 spread decreased by 5 yuan/ton to - 35 yuan/ton, a decline of 16.67%. The 2509 - 2510 spread increased by 5 yuan/ton to - 30 yuan/ton, a rise of 14.29%. The 2510 - 2511 spread decreased by 10 yuan/ton to - 30 yuan/ton, a decline of 50.00% [4]. - **Fundamental Data (Monthly)**: In April, the national industrial silicon production decreased by 41,400 tons to 300,800 tons, a decline of 12.10%. Xinjiang's production decreased by 43,300 tons to 167,500 tons, a decline of 20.55%. Yunnan's production increased by 1,200 tons to 13,500 tons, a rise of 9.35%.

Group 4: Polysilicon Industry Report Industry Investment Rating No information provided. Core View The SMM - quoted price of N - type re - feed material decreased by 1,000 yuan/ton to 36,500 yuan/ton, and the price of PS2507 increased by 235 yuan/ton to 35,860 yuan/ton. From the perspective of supply - demand fundamentals, the demand is highly likely to decline in May, and attention should be paid to the inventory accumulation expectation due to the non - decreasing supply. It was originally expected that production enterprises would increase maintenance and reduce production in May and postpone the restart plan, and slow inventory reduction was expected according to industry self - discipline. However, the uncertainty of joint production reduction has increased, and the polysilicon production is expected to increase with the restart of some enterprises. As it gradually enters mid - May and the first delivery is approaching in June, the warehouse receipts are expected to gradually increase. The warehouse receipts increased significantly by 310 to 450. Attention should be paid to the digestion ability of the market. Although the quality of the warehouse - receipt products traded in the futures market is higher, and special production lines need to be planned in advance for producing delivery products, which will increase the reduction power consumption and cost, so the expected price of deliverable products by enterprises will have a significant premium compared with ordinary spot products. The overall decline in the spot price will also lower the expected futures price. It is expected that the main fluctuation range of the futures price will move down to 34,000 - 40,000 yuan/ton, and the fundamentals will weaken [5]. Summary by Directory - **Spot Prices and Basis**: On May 21, the average price of N - type re - feed material decreased by 1,000 yuan/ton to 36,500 yuan/ton, a decline of 2.67%.
