黑色建材日报：悲观情绪退坡，黑色底部反弹-20250605

Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core Views - The pessimistic sentiment in the black commodities market is receding, leading to a bottom - up rebound. The glass and soda ash markets show a divergence between futures and spot prices due to cautious downstream procurement. The double - silicon market has a stabilized sentiment with alloy prices oscillating [1][3]. - Glass has a severe supply - demand contradiction with high inventory and lack of substantial production cuts. Soda ash faces continuous supply - demand surplus pressure and strong de - stocking pressure [1]. - For silicon manganese, low production due to profit issues and high inventory suppress prices, while manganese ore cost provides support. Silicon iron production is at a low level, but demand has some resilience, and short - term prices are affected by costs [3]. 3. Summary by Related Catalogs Glass and Soda Ash - Market Analysis - Glass: Futures rebounded significantly yesterday, but spot trading was weak with mainly rigid demand procurement and low speculative sentiment. Soda ash: Futures rose sharply following black commodities, while downstream procurement was cautious with mainly rigid demand replenishment [1]. - Supply - Demand and Logic - Glass: The supply - demand contradiction is severe, high inventory suppresses prices, and there is no substantial production cut. Long - term losses are needed to clear excess capacity, and later changes in production lines and raw material prices should be monitored. Soda ash: With new production projects coming online, the supply - demand surplus persists, and there is strong de - stocking pressure. Prices will be under pressure until the surplus situation eases, and attention should be paid to intermittent production line maintenance and new production [1]. - Strategy - Glass: Oscillating. Soda ash: Oscillating. No cross - period or cross - variety strategies are recommended [2]. Double - Silicon (Silicon Manganese and Silicon Iron) - Market Analysis - Silicon Manganese: Futures oscillated and rebounded with black commodities yesterday. The spot market was stable, and factories were reluctant to sell at low prices. The price in the northern and southern markets was 5400 - 5500 yuan/ton. Silicon Iron: Futures oscillated. The cash - inclusive ex - factory price of 72 - grade silicon iron in the main production areas was 5150 - 5200 yuan/ton, and the price of 75 - grade silicon iron was 5750 - 5850 yuan/ton [3]. - Supply - Demand and Logic - Silicon Manganese: Production is at a low level due to industry profits, iron - water production has slightly declined but remains high, and demand has some resilience. High factory inventory and registered warehouse receipts suppress prices, while low - level manganese ore port inventory has slightly increased, and falling manganese ore prices support alloy costs. Attention should be paid to the manganese ore supply side. Silicon Iron: Production has dropped to the lowest level in recent years due to enterprise losses, high iron - water maintains demand resilience, factory inventory de - stocking is weakening, downstream inventory is low, and short - term prices are affected by costs. Attention should be paid to electricity price changes and industrial policies [3]. - Strategy - Silicon Manganese: Oscillating. Silicon Iron: Oscillating [4].
