黑色建材周报：市场谨慎观望，玻碱震荡偏弱-20251012

Report Industry Investment Rating - Glass: Oscillating weakly [3] - Soda Ash: Oscillating weakly [3] Core Viewpoints - The glass and soda ash markets are both in a state of cautious waiting and oscillating weakly. The fundamentals of both are under pressure, with supply and demand contradictions remaining prominent. Attention should be paid to policy changes, supply dynamics, and downstream demand [1][2][3] Summary by Directory Market Analysis - Glass - Price: The glass main contract 2601 oscillated weakly, closing at 1,207 yuan/ton on Friday. The weekly average price of the domestic float glass market was 1,263 yuan/ton, a week-on-week increase of 85.17 yuan/ton [1][5] - Supply: Glass capacity utilization and output increased slightly, and the post-holiday supply was relatively stable [1] - Demand: The float glass market is in the traditional peak season, with stable shipments. After the holiday, the market is cautious, and purchases are mainly based on rigid demand [1] - Inventory: The total inventory of national float glass sample enterprises was 62.82 million heavy boxes, showing a significant increase. Continued attention should be paid to the inventory situation in October [1][33] - Supply and Demand Logic: Glass production is stable, and some production lines have been ignited. It is expected that production will continue to increase. The production and sales data weakened significantly during the holiday, and although there was a certain increase after the holiday, the overall situation remains weak. The glass price is at a relatively low level and is greatly affected by policies, but the weak fundamentals still strongly suppress the price [1] Market Analysis - Soda Ash - Price: The soda ash main contract 2601 oscillated weakly, closing at 1,240 yuan/ton on Friday. Some spot prices were lowered, and the spot-futures trading was good [1][5] - Supply: This week, the soda ash capacity utilization rate was 88.41%, a week-on-week decrease of 0.76%. The output was 770,800 tons, a week-on-week decrease of 0.85%. Some enterprises had short shutdowns during the holiday, resulting in a decrease in supply [2][29] - Demand: Demand is relatively stable. With the decline in spot and futures prices, market transactions have increased, but overall supply-demand contradictions still exist [2][31] - Inventory: This week, the inventory of domestic soda ash manufacturers was 1.6598 million tons, a 3.74% increase from before the holiday, indicating inventory accumulation [2][33] - Supply and Demand Logic: The supply-demand contradiction in soda ash remains severe. The second phase of Yuanxing's project was successfully ignited, and the subsequent supply pressure of soda ash will further increase. Demand is still weak due to the decline in photovoltaic glass and float glass. In the short term, soda ash will maintain a weak operation [2] Strategy - Glass: Oscillating weakly [3] - Soda Ash: Oscillating weakly [3] - Cross-variety: None [3] - Cross-period: None [3]
